However, in the prior art, the number of the various modules required to be used by the ZigBee switches with different path numbers is also different, for example, the 1-path switch, the 2-path switch, and the 3-path switch, and in the ZigBee switches with different path numbers, the number of the various modules required is as shown in table 1 below.
TABLE 1
The scene switch is used for binding a plurality of local devices, linking scenes, and controlling one key of the scene switch, such as a user automatically setting a getting-up scene, a leaving scene, a returning scene, a guest-meeting scene, a dining scene and a sleeping scene, and automatically changing light in six scene modes through the scene switch to control the opening of an intelligent scene mode.
Therefore, in the ZigBee switches with different path numbers, the number of keys, L ED lamps, the number of relays and the number of ZigBee switch paths are corresponding, only one zero-crossing detection module is related to a common switch, a buzzer is arranged in each ZigBee switch, namely, in the ZigBee switches with multiple paths, the front panel of each ZigBee switch is a linked switch panel, the rear panel of each ZigBee switch is three independent single linked switch panels, no communication link exists between the three devices, the three devices are independent of each other, three independent ZigBee chip controls are arranged between the three devices, and the three devices are independently communicated with a ZigBee gateway, so that the probability of mutual communication interference is improved, and when the ZigBee switches are controlled by the gateway to be switched on and off simultaneously, the devices with higher probability cannot be normally executed, the linked switch cost of the current scheme is higher, the user experience is poorer, the communication link is complex, the communication stability is poorer, and the like.
Based on the above analysis, an embodiment of the present invention provides a structure of a control system of a multi-functional parallel-row ZigBee switch, as shown in fig. 4, the ZigBee switch includes: a main control module 410 and an expansion module 420.
Wherein, the main control module 410 includes: a ZigBee chip 411, a key input unit 412, a buzzer 413, and a zero-crossing detection unit 414.
The ZigBee chip 411 is responsible for wireless data communication, control of the key input unit 412, the buzzer 413, and the zero-cross detection unit 414. The key input unit 413 may include a plurality of keys for controlling the network entry of the ZigBee switch and controlling the on/off state of the lamp. The buzzer 413 is used for providing prompt tones for the user when the user operates. The zero-crossing detection unit 414 is used for protecting the relay 423 and prolonging the service life of the relay.
The expansion module 420 comprises MCU expansion chips 421, L ED indicator light 422 and relay 423.
The MCU expansion chip 421 is configured to implement expansion control of the ZigBee switch through the I/O interface, and is further configured to receive key input information sent by the ZigBee chip 411, control a controlled device or a control relay 423 connected to the I/O interface to perform an operation corresponding to the key input information according to the key input information, so that the ZigBee switch implements an on/off state, and control L ED indicator 422 to display the information corresponding to the key input information.
It should be noted that, bidirectional data transmission is realized between the ZigBee chip 411 in the main control module 410 and the MCU extension chip 421 in the extension module 420 through Uart (Universal Asynchronous Receiver Transmitter/Transmitter), where Uart is a Universal serial data bus and is also used as one of Asynchronous serial communication protocols, and each character of transmission data is transmitted bit by bit, so that bidirectional transmission and reception of data can be realized.
The ZigBee chip 411 in the main control module 410 is connected with the MCU extension chip 421 in the extension module 420 through Uart, and the MCU extension chip 421 obtains the ZigBee switch control information sent by the ZigBee chip 411 and executes the ZigBee switch control information. For example, there are A, B, C three switch buttons in a triple row switch, wherein switch button a is set as a normal switch for controlling a bedroom light; the switch key B is set as a binding switch and used for controlling the bound switch; the switch button C is a scene switch for controlling a scene of going home. A. B, C the three switch keys correspond to three I/O interfaces on the MCU expansion chip 421 in the expansion module 420, respectively, where the correspondence relationship can be shown in Table 2.
TABLE 2
| Switch push-button | Message field | I/O interface |
| A | 00 | 1 |
| B | 01 | 2 |
| C | 10 | 3 |
When the user presses the switch key a, the ZigBee chip 411 may detect that the switch key a is pressed, and generate key input information in which a field for distinguishing the switch key is set to 00. The ZigBee chip sends the key input information to the MCU expansion chip 421 through Uart. After receiving the key input information, the MCU expansion chip 421 can read the key input information to know that the switch key a is pressed, and find the I/O interface 1 through the table 2, thereby controlling the controlled device corresponding to the I/O interface 1, i.e. the bedroom lamp.
It should be noted that, the user may also set controlled devices that can be controlled by each switch key through the control terminal, then issue a control instruction through the control terminal, send the control instruction to the ZigBee chip 411 by the ZigBee gateway, and send the control instruction to the MCU expansion chip 421 by the ZigBee chip 411 to execute the control instruction.
The embodiment of the invention realizes different functions of a plurality of switch keys by multiplexing one ZigBee chip 411 and one MCU (microprogrammed control unit) extension chip 421 by the plurality of switch keys, reduces communication interference, ensures communication efficiency and accuracy and simultaneously reduces the cost of the ZigBee switch compared with the prior art in which one switch key uses one ZigBee chip 411.
In the embodiment of the invention, a user logs in a control terminal by registering an account number, then the ZigBee gateway is allowed to add a ZigBee switch through the control terminal, the ZigBee switch is controlled and operated to enter a network adding mode, for example, the three-way switch enters the network adding mode, then the interaction binding between the ZigBee gateway and the three-way switch is waited to be successful, the ZigBee gateway stores the ZigBee switch information and updates the ZigBee gateway network information, the information of the successful adding of the three-way switch is informed to the control terminal through a cloud server, and the functions of each path of the ZigBee switch are modified and set through the control terminal (for example, each path of the switch can be respectively set into different functions according to the user requirements, the first path is a common switch, the second path is a scene switch, and the third path is a binding switch) or the functions are expanded (for example, a touch key is added for control according to the user requirements, a screen is displayed, and then the function setting is transmitted to the ZigBee gateway through the cloud server, the ZigBee gateway controls the original three-way switch to change the setting and reports the function setting result to the ZigBee gateway, the ZigBee gateway stores the result in the cloud server, so that the control terminal can also obtain the result information through the cloud server, meanwhile, the original three-way switch can also store related information, the ZigBee switch is restarted, the configuration information is not lost when the power is turned on or off, and the configuration function is required to be reset only after factory setting is restored or the network is added again.
It should be noted that, bidirectional data transmission is realized between the MCU expansion chip and the ZigBee chip through Uart, which does not involve low power consumption, so that data transmission speed is fast and communication quality is stable, and the ZigBee chip is externally connected with Flash for storing additional information or upgrading files, so that system expansion performance is stronger. Therefore, the mode that the gang switch is combined by a single ZigBee chip and an MCU extension chip in the aspect of structure can be realized, so that the system has the following advantages.
1. The price is cheaper. The original mode that three ZigBee modules are changed into the mode that a single ZigBee chip and an MCU (microprogrammed control unit) expansion chip are combined is adopted, and only one main control chip is used, so that peripheral control devices are reduced to 1/3 in the original scheme, and the cost of single ZigBee switch hardware can save about 2 ZigBee modules.
2. The ZigBee switch has higher stability. The mutual interference is reduced to 1 by three zigBees that wireless communication is afraid of most, and the mutual interference between the gang switch no longer exists, and communication between zigBee switch and the gateway is more stable, and user experience is better, and adopts the Uart agreement that supports two-way communication between MCU extension chip and the zigBee chip, and communication rate is fast, and is efficient, and stability is strong.
3. The expansibility is stronger. The ZigBee switch supports setting switch functions for multiplexing and expanding through a mobile phone APP. The multifunctional gang switch can be flexibly set into a common switch, a binding switch or a scene switch according to the requirements of the scheme, and the system has stronger expansibility.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present application without departing from the spirit and scope of the application. Thus, if such modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is intended to include such modifications and variations as well.
