Description

Data processing method, device and storage medium

This application is a divisional application for a patent with an application date of November 17, 2021, application number 202111359491.5, and invention name "Data processing method, device and storage medium".

Technical Field

The present disclosure relates to the field of communication technology, and in particular to a data processing method, device and storage medium.

Background technique

With the rapid development of the Internet of Things, the number of connected IoT devices, sensors, and actuators will continue to grow. At the edge of the IoT network, there are a large number of terminal nodes. Although these individual nodes may only require very low power and do not need to run continuously (start only when needed), the surge in the number of nodes will generate extremely high total power consumption. Energy harvesting technology refers to the recovery and conversion of unused energy such as thermoelectricity, vibration, motion, solar energy, etc. into electrical energy to power applications instead of batteries. It will become increasingly important in the deployment of the Internet of Things.

The key to realizing the battery-free power supply function of electronic devices through energy harvesting is that the electronic devices need to support low-power technology of ultra-low-power wireless protocols. The wireless data transmission of the Internet of Things includes standard protocols such as Wireless Fidelity (Wi-Fi), low-speed and short-distance transmission of the wireless Internet protocol (Zigbee), and Bluetooth. However, since Wi-Fi and Bluetooth are designed for large-scale data transmission, the biggest problem in applying battery-free electronic devices in the field of the Internet of Things is that the power consumption is too high and cannot meet the special needs of the personalized connection of things in the Internet of Things.

The present disclosure inserts device information and control information into data frames by setting the data format of data frames during wireless transmission between the control device and the controlled device, as well as the wireless transmission method between the control device and the controlled device. In the process of transmitting data frames, the device information and control information of the control device can be directly carried to the controlled device. Compared with data transmission through establishing an additional data channel, the transmission efficiency and accuracy of the data frames can be improved, and the transmission power consumption of the data frames can be reduced, and the standby time can be increased.

In some embodiments, the device information includes: a source identifier of the control device, a device type of the control device, and the control information includes: a control parameter;

The step of generating a first type of data frame according to the device information and the control information includes:

Generate a first type of data frame according to the source identifier of the control device, the device type of the control device and the control parameter; wherein the source identifier is used to determine the address field of the first type of data frame; the method further includes:

Determine the device type of the controlled device;

Determining, according to the device type of the controlled device and the control parameter, a type of command for controlling the controlled device;

generating a second type of data frame according to the device type of the controlled device and the type of the command;

The data types of the data carried by the preset bits in the frame control fields of the first type of data frame and the second type of data frame are different; and the target identifier of the controlled device is used to determine the address field of the second type of data frame.

In the embodiment of the present disclosure, the device information may include at least the source identification of the control device and the device type of the control device, and the control information may include at least the control parameters. The source identification (Source ID) may refer to the identification corresponding to the control device (for example, but not limited to the Internet Protocol address, the device unique number, etc.), and the source identification may be unique. The present disclosure may determine the corresponding control device according to the source identification, or may determine the device type of the controlled device by pre-customizing the device type of the controlled device, etc. The method of determining the device type of the controlled device is not specifically limited. The device type may refer to a single-open self-power switch, a double-open self-power switch, a receiver of 1 channel, a receiver of 2 channels, etc. The control device may receive the device type uploaded by the user, and then store it in the preset storage unit. When generating the first type of data frame, the device type is read from the preset storage unit.

The control parameters can be determined based on the user's operation detected by the control device. For example, if the control device is a single-pole switch, when the user changes the single-pole switch from an open state to a closed state, the control parameter can change from 0 to 1, etc.; if the control device is a pressure sensor, when the user presses the pressure sensor, the control parameter can be generated based on the pressing force detected by the pressure sensor.

The disclosed embodiment can generate a first type of data frame according to the source identifier of the control device, the device type of the control device and the control parameters. For example: the source identifier is used to determine the address field of the first type of data frame, the device type and control parameters of the control device can jointly determine the load part of the first type of data frame, etc. The types of commands used to control the controlled device may include: commands for data processing, or commands for control (also called device control commands), or commands for management (also called device management commands), etc. For example: device control commands such as status query, switch control, brightness control, ring control, and travel control; device management commands such as configuring the gesture sensing function and indicator light of the wall switch, reading the gesture sensing function and indicator light configuration of the wall switch.

The present disclosure can determine the type of command used to control the controlled device according to the device type of the controlled device and the control parameter, and then the electronic device can determine the device type of the controlled device and generate the second type of data frame according to the device type of the controlled device and the type of the command. For example, the device type of the controlled device and the type of the command can jointly determine the load part of the second type of data frame, etc.

The data types of the data carried by the preset bits in the frame control fields of the first type of data frame and the second type of data frame are different. The data carried by the preset bits may refer to data of any length or any position in the data frame. The type of data frame is not limited and can be customized according to actual usage requirements. For example: for the first type of data frame, it may refer to a data frame whose value of the lower 5 bits (b0, b1, ...b4 bits) in the frame control field is 00001, and for the second type of data frame, it may refer to a data frame whose value of the lower 5 bits in the frame control field is 00002. In a possible embodiment, the first type of data frame may refer to a data frame sent from the node end of the control device to the gateway end, and the second type of data frame may refer to a data frame sent from the gateway end to the node end, etc., wherein the gateway end may refer to an intelligent control center.

In the disclosed embodiment, a second type of data frame can be generated according to the device type of the controlled device and the type of the command, which can accurately determine the data structure of different types of data frames, refine the data frame type, reduce the workload of developers, etc.

In the disclosed embodiment, the data frame may be composed of a frame header, a payload (payload) (also referred to as a data portion, etc.), a footer, etc. The frame header may be composed of a frame control field (Frame Control), a frame sequence number (Sequence Number), and an address field (Addressing Fields). The frame control field contains basic frame information and is 16 bits in length. The frame sequence number is used to distinguish successively sent data frames, and the address field is used to determine the transmission direction of the data frame, etc. The payload part has a variable length, and the specific content is determined by the frame type; the footer may be a 16-bit cyclic redundancy check (CRC) value of the frame header and payload data, etc.

In the disclosed embodiment, the address field of the first type of data frame can be determined by the source identifier, and the address field of the second type of data frame can be determined by the target identifier. For example: if the electronic device determines that the data frame is of the first type, then it can be determined that the address field in the data frame is written with the source identifier 192.168.102.7 or a number of a specific number of bits, and if the data frame is of the second type, then it can be determined that the address field in the data frame is written with the target identifier 192.168.202.7 or a number of a specific number of bits, etc. The electronic device can simply and quickly determine the type or transmission direction of the data frame through the address field, which helps to improve the transmission efficiency. The load part of the first type of data frame can be composed of the device type and control parameters of the control device, for example: the control device determines that its own device type is a circular double-key switch (the corresponding number can be marked as D2, etc.), and the control parameter is 01 (that is, key a is disconnected, key b is closed, etc.), then the control device can write the device type D2 and the control parameter 01 into the load part of the data frame, etc.

In the disclosed embodiment, the source identifier can be used to determine the address field of the first type of data frame, the target identifier can be used to determine the address field of the second type of data frame, the device type and control parameters of the control device together constitute the load part of the first type of data frame, and can accurately set the data structure of different types of data frames, refine the data frame type, reduce the workload of developers, etc.

In some embodiments, the second type of data frame is composed of an address field of the second type of data frame and a payload portion of the second type of data frame.

In the embodiment of the present disclosure, the second type of data frame is at least composed of the address field of the second type of data frame and the load part of the second type of data frame, for example: the device type of the controlled device is a single-channel receiver, the first type is a basic status query, the first command content is empty, etc., which are written into the load part in sequence. After the electronic device determines the address field and the load part of the second type of data frame, it inserts other parts such as the frame header or the frame tail according to the preset rules to generate a complete second type of data frame. By adopting the above method, the present disclosure can accurately set the data structure of different types of data frames, clarify various information such as the transmission direction and the type of command, improve transmission efficiency, save operating power consumption, etc.

In some embodiments, the byte length corresponding to the payload portion of the second type of data frame is determined by the type of the command.

In the embodiment of the present disclosure, the byte length corresponding to the payload part of the second type of data frame may be variable, and the byte length may be determined by the type of the command. For example, if the command is a command for data processing, the byte length corresponding to the payload part of the second type of data frame may be 5 bytes, the byte length corresponding to the device control command may be 7 bytes, the byte length corresponding to the device management command may be 9 bytes, etc. The present disclosure can save transmission resources and quickly determine the type of command, etc. by using the payload part of the second type of data frame with different byte lengths.

In some embodiments, when the command is of the first type, the payload portion of the second type of data frame is determined by the device type of the controlled device, the first type and the first command content;

The first command content is determined by the type of the command.

In the disclosed embodiment, the first type may refer to a device control command. After obtaining the data frame, it is possible to first determine whether the address field of the data frame is a source identifier or a target identifier, obtain a determination result, and then determine the corresponding data frame type according to the determination result. After determining that the command carried in the data frame is of the first type (i.e., a device control command) by the data type of the data carried by the preset bit in the frame control field of the data frame, the first command content (Cmd Date) corresponding to the command of the first type can be determined according to the type of command (Cmd Type). When the electronic device determines that the type of command is a device control command, the corresponding command content can be determined only depending on the type of command, for example: the command content corresponding to the basic status query is empty, and the command content corresponding to the basic switch control is the first byte indicating the channel information, the second byte indicating the switching information, etc. (for example, but not limited to Byte 1: Channel, Byte 2: Switch), etc. Then the electronic device can determine the load part (Frame Payload) of the second type of data frame according to the device type (Device Type) of the controlled device, the first type (Cmd Type, 1Byte) and the first command content (CmdDate). The present disclosure sets the first command content to be determined by the type of the command, thereby being able to accurately determine the corresponding command content and the like.

In some embodiments, when the command is of the first type and the control parameter of the control device is empty, the payload portion of the second type of data frame is determined by the device type of the controlled device and the first type.

In the embodiment of the present disclosure, when the command is of the first type and the control parameter of the control device is empty, the load part of the second type of data frame can be determined only by the device type of the controlled device and the first type. For example, if the device type of the controlled device is a curtain motor and the first type is a basic status query, the load part of the second type of data frame can be jointly determined based on the device type being a curtain motor and the first type being a basic status query. The present disclosure can save transmission resources and improve transmission efficiency by adopting the above method.

In some embodiments, when the command is of the second type and the command of the second type has the first attribute, the payload portion of the second type of data frame is determined by the device type of the controlled device, the second type, and the second command content;

The second command content is determined by the type of the command.

The attributes of a command may refer to the indispensable properties of the command, such as encryption attributes and non-encryption attributes, public attributes and private attributes, common attributes and uncommon attributes, etc. In the disclosed embodiment, for commands with different attributes, the method of determining the payload part of the data frame may be different.

In the disclosed embodiment, the second type may refer to a device management command, which may include: configuring the gesture sensing function and indicator light of a wall switch, or reading the gesture sensing function and indicator light configuration of a wall switch, etc. The first attribute may refer to a public attribute, which may be understood as a limited enumeration of general management commands for controlled devices (such as but not limited to switch status, etc.). When the electronic device determines that the device management command is a public attribute, the second command content (Cmd Date) may be determined only by the type of the command (Cmd Type). For example, when the command type is a device management command and has a public attribute, the second command content may be turning the indicator light on or off, etc.

Then the electronic device can determine the payload part (Frame Payload) of the second type of data frame according to the device type (Device Type), the second type (Management Cmd Type) and the second command content (Cmd Data) of the controlled device. For example, the device type of the controlled device is a 3-way wall switch with gesture sensing function, the second type is to configure the gesture sensing function and indicator light of the wall switch, and the second command content is to turn on the indicator light, etc., which are written into the payload part in sequence. After the electronic device determines the address field and payload part of the second type of data frame, it inserts other parts such as the frame header or frame tail according to the preset rules to generate a complete second type of data frame.

In an embodiment of the present disclosure, when the command is of the second type and the command of the second type has the first attribute, the second command content corresponding to the command of the second type can be determined, the payload portion of the second type of data frame can be determined according to the device type of the controlled device, the second type and the second command content, and the second type of data frame can be generated according to the address field of the second type of data frame and the payload portion of the second type of data frame. By adopting the above method, the present disclosure can accurately set the data structure of different types of data frames, clarify various information such as the transmission direction and the type of command, improve transmission efficiency, save operating power consumption, etc.

In some embodiments, when the command is of the second type and the command of the second type has a second attribute, the payload portion of the second type of data frame is determined by the device type of the controlled device, the second type and the third command content;

The third command content is determined by the device type of the controlled device and the type of the command.

In the disclosed embodiment, the second type may refer to a device management command, which may include: configuring the gesture sensing function and indicator light of a wall switch, or reading the gesture sensing function and indicator light configuration of a wall switch, etc. The second attribute may refer to a private attribute, which may be understood as a command specific to a certain type of controlled device (for example, but not limited to detecting facial expressions, etc.). When an electronic device determines that a device management command is a private attribute, the third command content (Cmd Date) needs to be determined by the device type (Device Type) and the type of command (Cmd Type) of the controlled device. For example, when the command type is a device management command and has a private attribute, the second command content corresponding to device type A can be sensing distance, and the third command content corresponding to device type B can be gesture sensing control, etc.

Then the electronic device can determine the payload part (Frame Payload) of the second type of data frame according to the device type (Device Type), the second type (Management Cmd Type) and the third command content (Cmd Data) of the controlled device. For example: if the device type of the controlled device is a dimmable device with gesture sensing function, the second type is to read the gesture sensing function detected by the dimmable device, and the third command content is to turn on the indicator light, the dimmable device with gesture sensing function, the gesture sensing function detected by the dimmable device, and the indicator light turn on can be written into the payload part in sequence. After the electronic device determines the address field and payload part of the second type of data frame, it inserts other parts such as the frame header or frame tail according to the preset rules to generate a complete second type of data frame.

In an embodiment of the present disclosure, when the command is of the second type and the command of the second type has a second attribute, the third command content corresponding to the command of the second type can be determined according to the device type of the controlled device, the payload part of the second type of data frame can be determined according to the device type of the controlled device, the second type and the third command content, and the second type of data frame can be generated according to the address field of the second type of data frame and the payload part of the second type of data frame. By adopting the above method, the present disclosure can accurately set the data structure of different types of data frames, clarify various information such as transmission direction and command type, improve transmission efficiency, save operating power consumption, etc.

In some embodiments, the method further comprises:

Determine a third type of data frame according to the second type of data frame; wherein the data types of the data carried by the preset bits in the frame control fields of the third type of data frame, the first type of data frame and the second type of data frame are different; the third type of data frame comprises: an address field and a load part, the address field of the third type of data frame is determined by the source identifier; the load part of the third type of data frame is determined by the device type of the controlled device, the type of the command and the fourth command content;

The fourth command content is determined by the device type of the controlled device, or by the type of the command, or by both the type of the command and the device type of the controlled device.

In the disclosed embodiment, the electronic device can determine the third type of data frame based on the second type of data frame. The third type of data frame can carry the external environment detected by the controlled device, as well as the current operating status and other information. The third type of data frame can at least include: an address field and a load part. The address field of the third type of data frame is determined by the source identifier and can be used to determine the corresponding control device. The load part of the third type of data frame is determined by the device type of the controlled device, the type of the command and the fourth command content. The third type of data frames corresponding to the second type of data frames generated in different ways may also be different. For example: when the type of command is a device control command, the corresponding type of data frame may be the first type of the third type; when the type of command is a device management command, the corresponding type of data frame may be the second type of the third type; when the device management command has a public attribute, the second type of the third type of data frame also has a corresponding public attribute; when the device management command has a private attribute, the second type of the third type of data frame also has a corresponding private attribute, etc.

For the first type of third-category data frame, the fourth command content can be determined only by the device type of the controlled device; for the second type of third-category data frame with public attributes, the fourth command content can be determined only by the type of the command; for the second type of third-category data frame with private attributes, the fourth command content needs to be determined jointly by the type of the command and the device type of the controlled device.

By adopting the above-mentioned method, the present disclosure can accurately and timely determine the data transmission status of the control device and the controlled device, save the operating power consumption of the electronic device, etc.

In some embodiments, the frame control field of the second type of data frame carries forwarding information;

The forwarding information is used to trigger a function of the controlled device forwarding data to other controlled devices.

In the embodiments of the present disclosure, the forwarding information may include information such as the number of forwarding times and the forwarding time interval. The controlled device may have the function of forwarding data so as to increase the transmission distance of the data frame. For example: the electronic device sends the second type of data frame to the controlled device A at the first position, and then the controlled device A can send the second type of data frame to the controlled device B at the second position, and then the controlled device B can send the second type of data frame to the controlled device C at the third position, etc. In the process of forwarding data, the controlled devices A, B and C can both execute the corresponding command content and forward it, or just forward it without executing the corresponding command content, etc. The controlled devices A, B and C can also filter the second type of data frame or insert new information, etc., and then forward it, etc., which is not specifically limited in the present disclosure.

In the process of forwarding, if the forwarding is unlimited, the forwarding cannot be stopped or the frequency band is occupied too much, which affects the transmission performance of the wireless transmission system. Therefore, a certain forwarding stop rule can be set. The electronic device can be set to write the forwarding number into the frame header (FRAME Header) of the data frame, and when a certain forwarding number (for example, greater than 2 times) is reached, the forwarding is stopped. For example: set the forwarding to stop when it is greater than 2 times. When the controlled device receives the forwarded second-class data frame, but reads the forwarding number as 3, it stops forwarding to other controlled devices, and the controlled device terminates the forwarding process. The controlled device A can update the current forwarding number (Repeater Counter, RC) in the second-class data frame received from the intelligent control center from 0 to 1, and then the controlled device B can update the current forwarding number in the second-class data frame received from the controlled device A from 1 to 2, etc., until the preset forwarding number of 3 times is reached. The present disclosure can improve the transmission distance of the data frame by adopting the above method.

In some embodiments, the payload portion of the second type of data frame carries channel information;

The channel information is used to determine different transmission channels corresponding to different data frames.

In an embodiment of the present disclosure, the payload portion of the second type of data frame carries channel information, and the channel information is used to determine different transmission channels corresponding to different data frames. The electronic device sends the second type of data frame to the controlled device, including: determining the target transmission channel corresponding to the device type according to the device type and a preset mapping relationship; wherein the mapping relationship is used to characterize the association relationship between the device and the transmission channel; and sending the second type of data frame to the controlled device through the target transmission channel. For example: if the device type of the control device is a square single-button switch, then the electronic device can transmit data frames related to the control device through the first channel (Channel); if the device type of the control device is a round three-button switch, then the electronic device can transmit data frames related to the control device through the second channel. The present disclosure, by adopting the above-mentioned method, helps electronic devices to quickly and accurately transmit data frames, avoid the situation of disordered data frame transmission, and improve transmission efficiency.

In some embodiments, at least one of the first type of data frames, the second type of data frames, and the third type of data frames may include a payload portion, and the payload portion or other portions may carry channel information, which is not specifically limited in the present disclosure.

In some embodiments, the first type of data frame and/or the second type of data frame carries verification information;

The verification information is used to: divide the first type of data frame and/or the second type of data frame from a preset position into a first part and a second part, verify the first part to obtain a first verification result corresponding to the first part; verify the second part to obtain a second verification result corresponding to the second part, or verify the first part, the first verification result and the second part to obtain the second verification result.

In some embodiments, at least one of the first type of data frames, the second type of data frames, and the third type of data frames may carry verification information, which is not specifically limited in the present disclosure.

In the disclosed embodiment, a data frame may be checked twice, and the check may refer to a cyclic redundancy check code (CRC), which is a check method with error detection and correction capabilities. The check information may include information such as a check code, and the check information is used to: divide the data frame from a preset position into a first part and a second part, check the first part, and obtain a first check result corresponding to the first part; check the second part, and obtain a second check result corresponding to the second part, or check the first part, the first check result, and the second part to obtain the second check result. For example: if the length of the data frame is 5 bytes, then the electronic device can insert check information A (check code A) and check information B (check code B) after byte No. 1 and byte No. 5, respectively. The electronic device can perform a first check on byte No. 1 according to the check information A, and obtain a check result a. The electronic device can perform a second check on bytes No. 2-5 according to the check information B, and obtain a check result b, or the electronic device can perform a second check on bytes No. 1, bytes No. 2-5, and check result a together according to the check information B, and obtain a check result b, etc. The present disclosure helps to improve verification efficiency and accuracy by adopting the above-mentioned method.

In some embodiments, the first type of data frame and/or the second type of data frame includes a frame header portion, and the frame header portion is determined by protocol version information, and the protocol version information is used to determine a data protocol type for data processing.

In the embodiment of the present disclosure, any data frame of different types such as the first type of data frame and/or the second type of data frame may include a frame header portion, and the frame header portion may be determined by protocol version information, and the protocol version information is used to determine the data protocol type of data processing, for example: the frame header corresponding to the 433 protocol is divided into 0001, and the frame header corresponding to the 2.4G protocol is divided into 0010, etc. The information contained in the payload portion of data frames of different protocols (such as the first type of data frame, or the second type of data frame, or the third type of data frame, etc.) can be exchanged with each other. The present disclosure helps to improve the generation efficiency of data frames between different protocols by adopting the above method.

In some embodiments, at least one of the first type of data frames, the second type of data frames, and the third type of data frames may include a frame header portion, which is not specifically limited in the present disclosure.

The data processing method in the embodiments of the present disclosure may be applied to a control device, an intelligent control center, a controlled device, etc. The present disclosure does not specifically limit the execution subject of the data processing method.

In an embodiment of the present disclosure, it is possible to obtain device information of a control device and control information generated by the control device; a first type of data frame is generated according to the device information and the control information; wherein the first type of data frame includes an address field and a load part, the first part of the device information constitutes the address field of the first type of data frame, and the second part of the device information and the control information together constitute the load part of the first type of data frame. The present disclosure can improve the transmission efficiency and accuracy of data frames by setting the data format of data frames during wireless transmission between a control device and a controlled device, as well as the wireless transmission method between a control device and a controlled device, and can also reduce the transmission power consumption of data frames, increase the standby time, etc.

FIG. 2 is a second flowchart of a data processing method according to an exemplary embodiment. As shown in FIG. 2 , the data processing method is applied to a controlled device and mainly includes the following steps:

In step 201, the state information of the controlled device is sent to the intelligent control center, so that the intelligent control center matches the control device and the controlled device according to the state information of the controlled device and the state information of the control device;

In step 202, a matching result is received from the intelligent control center; wherein the matching result is used to establish a communication connection between the control device and the controlled device.

Here, the controlled device (also referred to as a receiver) may be a device that can receive and execute commands and has a wireless transmission function, for example, it may refer to a device that is used to receive and execute control, management, and other commands and has a wireless transmission function such as radio frequency wireless transceiver, infrared transceiver, Bluetooth transceiver, WiFi transceiver, etc. In some embodiments, the controlled device may include: wall switches, single-channel actuators, multi-channel actuators, electric curtains, lamps, televisions, air conditioners, and other devices.

In the disclosed embodiments, the intelligent control center may include: terminal devices, gateway devices or cloud servers, for example, mobile terminals or fixed terminals. Among them, mobile terminals may include: mobile phones, tablet computers, laptop computers or wearable devices, and may also include smart home devices, for example, smart speakers. Fixed terminals may include: desktop computers or smart TVs. The intelligent control center may refer to a transit device used to match, filter or cut commands during wireless transmission between the control device and the controlled device. The control device may first send a command to the intelligent control center, and then the intelligent control center forwards the processed command to the controlled device that matches the control device. Of course, data frames can also be transmitted between the controlled device and the control device.

In a possible embodiment, the intelligent control center may also refer to a module or chip with intelligent control functions, etc., which may be embedded in other devices, etc. The present disclosure does not specifically limit the representation of the intelligent control center. For example, the intelligent control center may refer to a module or unit in a control device, or the intelligent control center may refer to a module or unit in a controlled device, that is, the control device or the controlled device may include the functions of the intelligent control center, etc.

The controlled device can send the state information of the controlled device to the intelligent control center, so that the intelligent control center matches the control device and the controlled device according to the state information of the controlled device and the state information of the control device. The state information of the controlled device can include the address identification of the controlled device, its own movement, brightness, loudness and other state information, and the state information of the control device can include the address identification of the control device, its own opening and closing degree, detected control parameters and other state information. For example: the intelligent control center matches the control device with a certain address identification and the controlled device with a certain address identification according to the automatic setting of the assumption or certain rules, and sends the address identification information of the control device to the controlled device, so that the controlled device can directly control the controlled device later after storing the address identification information of the control device. Once the matching relationship is established through the address identification, all control information of the control device can be applied to the controlled device. For example, if a control switch is on when it is on and off when it is off when it is on, once the switch is matched with the controlled device, the controlled device is turned on when the top of the switch is pressed, and the controlled device is turned off when the bottom of the switch is pressed. The intelligent control center determines that the state information of the controlled device A is the loudness from high to low, the state information of the controlled device B is the brightness from on to off, etc., the state information of the control device a is from closed to open, the state information of the control device b is the pressure level gradually increasing, etc. The intelligent control center can obtain the controlled device A matching the control device b, the controlled device B matching the control device a, etc. according to the pre-set matching strategy.

In the matching process, matching can be performed based on the common information contained in the status information of the controlled device and the status information of the controlling device. For example: the status information of the controlled device C carries the matching identifier 1, and the status information of the controlling device D also carries the matching identifier 1, then it can be determined that the controlled device C matches the controlling device D. In the disclosed embodiment, matching can also be performed based on the device type carried in the status information of the controlled device and the device type carried in the status information of the controlling device. For example: the device type carried in the status information of the controlled device E is a channel type, and the device type carried in the status information of the controlling device F is a single-open self-power type. By matching a pre-set channel type with the single-open self-power type, it is determined that the controlled device E matches the controlling device F, etc.

After obtaining the matching result, the intelligent control center can send the matching result to the control device and the controlled device respectively, so that the control device and the controlled device can directly transmit signals based on the matching result without passing through the intelligent control center.

The controlled device can receive the matching result from the intelligent control center; wherein the matching result is used to establish a communication connection between the control device and the controlled device, for example: a communication connection between controlled device A and control device B, a communication connection between controlled device B and control device A, etc.

In the disclosed embodiment, the state information of the controlled device can be sent to the intelligent control center, so that the intelligent control center can match the control device and the controlled device according to the state information of the controlled device and the state information of the control device; and receive the matching result from the intelligent control center; wherein the matching result is used to establish a communication connection between the control device and the controlled device. The disclosed controlled device matches with the control device by sending its own state information, which can improve the matching efficiency and matching accuracy between the control device and the controlled device.

In order to avoid air conflicts when multiple controlled devices send status information, the first time interval can be a random number. For example: using the target identifier of the controlled device itself as the source of random numbers, since the target identifier of each controlled device is different, different time intervals can be generated. It is also possible to use a different identifier burned into the controlled device as the source of random numbers when burning the program, or to use data read out of an analog-to-digital converter that is not connected to any input as a random number, etc.

As shown in FIG4A , a transmission schematic diagram of wireless data transmission can be represented. In order to save power, the transmitting device can only transmit signals without performing additional receiving work, ensuring that the transmitting device 401 is in an extremely power-saving state. The transmitting device 401 can refer to a self-generating switch, a battery switch, a sensor and other devices, and the receiving device 402 can refer to a wall switch, a single-channel actuator, a multi-channel actuator, an electric curtain, a lamp and other devices. There are many types of receiving devices 402, and the receiving device 402 and the intelligent control center 403 can communicate bidirectionally, obtain data from each other, and send control commands, etc. The transmitting device 401, the receiving device 402, and the intelligent control center 403 can all communicate with each other, and there are many options for the information flow of the entire system. For example: you can choose to transmit the transmitting device 401 to the receiving device 402, the receiving device 402 to the intelligent control center 403, or you can choose to transmit the transmitting device 401 to the intelligent control center 403, the intelligent control center 403 to the receiving device 402, etc. The specific direction of the information flow can be set by a preset protocol, or it can be configured by the user, and the order of the information flow is executed by simulating the configuration order of the user. For example, if the user configures the intelligent control center 403 first and then configures the receiving device 402, the direction of the information flow is from the transmitting device 401 to the intelligent control center 403 first, then to the receiving device 402, and vice versa.

In a possible embodiment, in the wireless data transmission mode, the corresponding protocol physical layer parameters can be customized. For example, the center frequency can be 300MHz-990MHz, 2GHz-6GHz, the transmission power can be -10dBm-50dBm, the receiving sensitivity can be arbitrary, the modulation mode can be Gaussian Frequency ShiftKeying (GFSK), Amplitude Shift Keying (ASK), Frequency ShiftKeying (FSK), etc., and the data transmission rate (air rate) can be 1kbps-2Mbps.

As shown in FIG. 4B , a schematic diagram of a message data structure can be represented. The physical layer can be composed of a preamble (for example, but not limited to, a length of 4 bytes), a synchronization word (for example, but not limited to, a length of 4 bytes) and a data link layer frame (for example, but not limited to, a custom X-byte length). For the link layer, the data link layer frame may include information such as data length (for example, but not limited to, a length of 1 byte), a message (for example, but not limited to, a custom Y-byte length) and a cyclic redundancy check (CRC check) (for example, but not limited to, a length of 2 bytes). For the network layer, the message may include a frame control field (FRAME CTRL) (for example, but not limited to, a length of 1 byte), a source identifier (SOURCE ID) (for example, but not limited to, a length of 4 bytes), a command type (TYPE) (for example, but not limited to, a length of 1 byte), a command content (DATA) (for example, but not limited to, a custom Z-byte length), and the like.

The data length of the command content of the message transmitted by the transmitter, intelligent control center or receiving device can be changed, and there will be different data lengths according to different message command types. For example, for the transmitter, the length of DATA can be 1Byte. The transmitter needs certain trigger conditions to transmit data. The trigger condition can be that the transmitter is powered on, it can also be timed transmission, or the sensor data in the transmitter changes. The transmitter can load the content of DATA data according to the signal collected by the sensor. If the sensor data is empty, the sensor data is not loaded. Then load the TYPE data. The TYPE data defines the type of the transmitter. For example, the transmitter can be defined as a switch, and the transmitter can also be defined as the type of switch. For example, the switch of the transmitter is defined as a flip type. Every time the switch is pressed, the receiving device performs a flip operation after receiving a flip type message. The type of the transmitter switch can also be defined as a fixed type. Then the receiving device will perform a fixed on or off operation every time it receives a message.

You can also define other types of transmitters, or the type and model of a switch, etc. The receiving device can perform corresponding actions according to the defined type. FRAME CTRL defines the type of transmitted signal, such as: a signal sent by the transmitter, or a device control command, or a device status report command, or a device management command, or a device management command response, etc. SOURCE ID defines the matching information of the transmitted signal. Only when the source identifier of the transmitter matches the target identifier of the receiving device, the receiving device will perform the corresponding function. This information is also the information to be set for the configuration establishment relationship between devices. The data length can be 1 Byte, which defines the overall length of the sent message and provides data length information for subsequent program parsing of the message. The CRC check is 2 Bytes, or it can be 1 Byte or other digits. When the CRC check is correct, the message is considered to be a valid message. If the check is incorrect, it is an invalid message, etc.

In a possible embodiment, the preset bit in the frame control field of the data frame may refer to the lower 5 bits b0-b4, the first type of data frame may include a passive wireless sensor (switch) command, the second type of data frame may include a device control command and a device management command, and the response data frame may include a device status report and a device management command response, etc. The data types of the data carried by the preset bits corresponding to different types of commands may be 0, 0x1F (0b111111), 0x1E (0b111110), 0x1D (0b111101) and 0x1C (0b111100), respectively.

The data format of the integrated link layer + network layer can be: message 1 (M bytes), CRC check (2 bytes), message 2 (N bytes), CRC check (1 byte), etc.

In a possible embodiment, FRAME CTRL can be set to 0x00 and TYPE to 0x55, which means that the command type is a transmitter, and the transmitter type is a switch. The switch can include six buttons, and the corresponding data is the 0th to 5th bit of DATA. When the button is triggered, the corresponding bit of DATA is 1, and when it is not triggered, the corresponding bit of DATA is 0. When all the buttons are triggered, the DATA data is 0x3F. After receiving the signal, the receiver first matches whether it is a controlled switch, and then controls the state of the receiving actuator according to the trigger state of the button.

In a possible embodiment, FRAME CTRL can be set to 0xAA and TYPE to 0xA1, which is a control command for a single-channel receiving device. The first byte of the DATA data is the control command, 0x01 represents the query status, 0x02 represents the need to control the switch, and the second byte of DATA represents the state to be controlled, 0x01 represents on, and 0x02 represents off.

In a possible embodiment, FRAME CTRL can be set to 0xA5 and TYPE to 0xA2, which is a device status report command for a single-channel receiving device. The first byte of DATA represents the specific device type, and the second byte of DATA represents the status of the specific controlled device. There may also be multiple bytes representing the status of the specific controlled device, depending on the type of the controlled device.

In a possible embodiment, FRAME CTRL can be set to 0xA6 and TYPE to 0xA3, which is a single-channel receiver management command.

In a possible embodiment, a FRAME Header can be added before the data of FRAME CTRL to identify information such as the protocol version number. Of course, the information contained in FRAME CTRL and FRAME Header can be exchanged with each other as long as it is clearly defined in advance. It can also include information on the number of forwarding times. In some applications, the receiving executor is allowed to start the forwarding function to increase the transmission distance. However, if the forwarding is unlimited, the forwarding cannot be stopped or too much frequency band is occupied, which affects the transmission performance of the wireless system. Therefore, it is more important to set certain forwarding stop rules. In the protocol, we can design that forwarding stops when a certain number of forwarding times is reached. For example, it is set to stop after forwarding 2 times. When the receiving executor receives the forwarded message, but reads the forwarding number as 3, it stops forwarding outward, and the receiving executor terminates the forwarding process.

In a possible embodiment, for the transmitter, the power generation of the electromagnetic transducer is about 100uJ to 1000uJ, the power generation efficiency of light energy is about 100W/m2, and the collection utilization rate of long-distance wireless transmission power generation is lower, so it is necessary to optimize the wireless transmission protocol (data structure of data frame, etc.) to utilize these energies. The traditional method of increasing the transmission power to achieve long-distance transmission cannot meet the needs of micro-energy power generation. By optimizing the wireless transmission method, the energy utilization rate is improved and energy is saved, but the transmission distance cannot be reduced due to energy saving. Therefore, it is also necessary to ensure that the transmission distance is far enough, and the greater the ratio of distance to energy, the better. In the embodiment of the present disclosure, the distance-to-energy ratio can be guaranteed to be greater than 0.2 meters/uJ at a wireless transmission frequency of 300MHz-990MHz, and greater than 0.1 meters/uJ at a wireless transmission frequency of 2GHz-6GHz. The embodiment of the present disclosure can be applied to the control system of smart homes, and can be used to make smart switches, electric curtains, sensors, smart home appliances, garbage disposers, smart toilets, electric clothes drying racks and other products.
