Description

Group control method of smart home system

technical field

The invention belongs to the field of smart home, and in particular relates to a grouping control method of a low-power bluetooth mesh network, which can be applied to intelligent control application fields such as smart home and smart office.

Background technique

With the rapid development of mobile smart devices, the intelligence of household devices has become an inevitable trend of development. A smart home system that integrates technologies such as the Internet of Things, sensors, security encryption, and automatic control has emerged as the times require. The fundamental purpose of smart home is to integrate the equipment in life, build an efficient residential environment and family affairs management system, and improve the flexibility, safety, comfort and efficiency of household equipment. However, there is no uniform standard protocol for the BLEmesh network currently used in smart home systems. Most of the existing smart home systems use single control and global control, and there is no perfect mechanism for group control within the system. It reduces the practicability and flexibility of smart homes; in addition, although some smart home systems also have group control mechanisms, their control methods have strict requirements on the number of nodes in the system, which limits their application in large-scale smart homes.

Contents of the invention

The purpose of the present invention is to provide a grouping control method for smart home, which improves the flexibility and efficiency of user operations in the smart home system, and greatly improves user experience.

The present invention comprises the following steps:

(1) Set up a smart furniture system. Smart home nodes apply for network access through broadcasting. Smart terminals obtain a list of smart home nodes through active scanning, and smart terminals add smart home nodes in the list to the network;

(2) Assign a group control address, the intelligent control terminal assigns the group control address to the smart home node, and the smart home node saves the group control address;

(3) Group control, the smart terminal sends a control command carrying the group control address, the smart home node receives the command, and judges whether to respond and whether to forward the command.

The above-mentioned smart home system includes N smart home nodes, N≥1; each smart home node is a device that supports Bluetooth Low Energy (BLE); the smart terminal is a smart mobile device that supports BLE, such as: smart phone, tablet computer.

The above-mentioned building of the smart furniture system includes two steps:

(a) The smart home node transmits some identification information of itself through the built-in Bluetooth module, and the smart control device actively scans the smart home nodes within the Bluetooth coverage of the smart control device to obtain a list of nodes, and the smart control device selects one of the nodes, and establish a wireless connection with it;

(b) The intelligent control terminal interacts with the connected smart home node through data interaction to determine whether the other party is a device in an existing smart network, and sends corresponding configuration information to the device according to the judgment result. There are two situations at this time :

i. The smart home node has not joined the smart home network, and the smart control terminal needs to configure the node to join the network. The configuration includes: the smart control terminal saves the device ID, the smart control terminal distributes the network key to the smart home node, and the smart control terminal configures the smart home node status information;

ii. The smart home node has joined the smart home network. At this time, the smart home node belongs to the equipment in the network and is in normal operation.

The specific steps for assigning the group control address above are as follows:

(a) The intelligent control terminal performs active scanning to obtain a list of network-connected nodes within its communication range;

(b) The intelligent control terminal opens the network-connected node list, and selects n devices, n≥1, and divides them into a group;

(c) Sending group control addresses to the selected devices in sequence.

The specific steps of the above-mentioned group control are as follows:

(a) The intelligent control terminal sends a control command to the smart home node establishing a wireless connection with it, and the control command has a corresponding group control address;

(b) The smart home node that receives the control command judges the group control address carried by the control command and the group control address saved by the smart home node, and the judgment result is:

b1. If the group control address does not match the local address, the control command is forwarded;

b2. The group control address matches the local address, and it is a single control, then the smart terminal will respond to the control command;

b3. The group control address matches the local address, and it is controlled by the whole group, then the smart terminal will respond to the control command and forward the control command.

The group control address assigned by the above intelligent control terminal to the smart home node includes the following two parts:

A byte-sized group number, used to distinguish different groups, such as: group 1, group 2;

A byte-sized node serial number, which is used to distinguish different nodes in the group, such as: the first node in the first group, and the second node in the first group.

A group in the above-mentioned smart home system can contain multiple nodes, so as to control multiple nodes at the same time.

The aforementioned smart home node can store multiple group control addresses, that is, one smart home node can be divided into multiple groups.

The above-mentioned smart control terminal can group the smart home nodes in the smart home system at any time after the devices are connected to the network.

Compared with the prior art, the present invention has the following advantages:

(1) Since the present invention adds a two-byte group control address in the control command, and adds a corresponding group control processing mechanism in the smart home node, the user's flexibility in controlling the smart home system is greatly improved. Optimized user experience.

(2) The present invention can control multiple nodes at the same time due to the adoption of multiple smart home nodes in a group; multiple group control addresses can be stored in one smart home node, so that one smart home node can be divided into multiple groups, making group control more flexible.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that, in each implementation manner of the present invention, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in each claim of the present application can be realized.

Referring to FIG. 1 and FIG. 2 , step 101 to step 103 are the process of building a smart home system. Intelligent control terminals (such as smart phones, tablet computers) are installed with dedicated applications for building networks, configuring networks, controlling networks, disbanding networks, etc.; smart home nodes are devices that support Bluetooth Low Energy (BLE), such as: LED, sound.

Specifically, in step 101, the smart control terminal establishes a wireless connection with the smart home node. For example, both parties support Bluetooth low energy connection, and a smart home node and a control terminal (such as a smart phone) can establish a wireless communication link through Bluetooth low energy pairing. For example, a smart home node transmits some of its own identification information through a built-in Bluetooth module, and the smart control device opens a dedicated APP to actively scan for smart home nodes within the Bluetooth coverage of the smart control device. Bluetooth (BLE) sends a connection request to the smart home node, and the smart home node responds to the connection request, so that a wireless communication link is established between the control terminal and the smart home node. The manner of establishing the wireless communication link is not limited to the above, and will not be repeated here.

In step 102, the control terminal interacts with the connected smart home node through data interaction to determine whether the other party is a device node in an existing smart network. There are two situations at this point:

1. The smart home node has not joined the smart home network. At this time, the intelligent control terminal needs to configure the node to access the network. The configuration content includes: the intelligent control terminal saves the device ID, the intelligent control terminal distributes the network key to the device, and the intelligent control terminal configures device status information, etc.;

2. The smart home node has joined the smart home network. At this time, the smart home node belongs to the equipment in the network and is in normal operation.

After the network configuration information interaction is completed, the two parties can disconnect, and the smart home node enters the normal working state at this time; the smart home node and the smart control terminal can also continue to be connected, and the devices connected to the smart terminal and that have joined the network will directly receive And forward the message sent by the intelligent control terminal, and other devices in the network are in the listening state.

Step 104 is the process of assigning a group control address. In this step, the intelligent control terminal assigns a group control address to the selected smart home node, referred to as a group control address. As shown in Figure 3, if the user wants to set a device as the third device in the first group, the user only needs to select the device on the smart terminal page, click the group button, and input 0103. address. The data format of the group control address is shown in Figure 4.a, a total of 2Byte data, in which the first byte is the group serial number, and the second byte is the node serial number. set up. As shown in Figure 4.b, 0103 indicates that the node belongs to the first group No. 3 device in the smart home system, and then it will respond to all commands issued by the smart home system for the first group, and at the same time respond to its own The command.

In step 105, the smart home node works normally in the established or joined smart network, such as broadcasting its own information and receiving information sent by other nodes.

Step 106 to step 110 are grouping control procedures. In step 106, the smart home node judges whether it is currently in the following state: receiving a control command for the smart home node; or receiving an instruction that needs to be forwarded; or, the status of the smart home node changes, and other nodes need to be notified .

Specifically, in the same smart home system, a control terminal (such as a smart phone or a remote control) can send a control command with a group control address, and the smart home node that receives the control command will save the data stored in the smart home node. Compared with the group control address carried in the control command, it is judged whether the control command is a control command sent to the smart home node, or whether it is a control command sent to the group where the smart node is located. If the comparison result does not match, it means that the control command is sent to other smart home nodes, that is, the control command needs to be forwarded.

If the comparison result matches, there are two cases: one is that the control command is sent to the smart home node alone, and it needs to respond to the control command, that is, perform the operation indicated by the control command. After the operation is completed, you can Notify the control terminal of the state change of the smart home node as required; the other is that the control command is a control command sent to the group where the smart home node is located. In this case, the smart home node has to respond to the control command In addition, the control command must be forwarded to inform other smart home nodes in the group.

Therefore, the smart home node receiving the control instruction in this embodiment may be in the following three situations:

(1) A control command is received, but the group control command carried by the control command does not match the group control command stored in the smart home node, and the smart home node must forward the command;

(2) Receive a control command for this smart home node alone. The control command may be sent by the control terminal or forwarded by other smart home nodes, and the smart home node must respond to the command;

(3) After receiving a control command for the group where the smart home node belongs, the smart home node should respond to the command and forward the command.

When the smart home node judges that it is currently in one of the above three situations, it makes corresponding processing, and then returns to step 105, and continues to broadcast its own information and receive other node information.

The response instructions described in steps 109 and 110 include executing commands and returning status information. For example, after the smart home node executes the command, it determines that the state of the smart home node has changed (for example, the air conditioner is turned on, the current light color of the BLE lighting device is yellow, etc.), and the change information is sent back to the smart control terminal , the control terminal presents it to the user after receiving the state change information sent by other nodes.

To sum up, in the process of group control, through the forwarding of control commands by smart home nodes, it can be guaranteed that any smart home node (regardless of whether the device is within the signal coverage of the control terminal) can receive the same smart home node. Control instructions in the control terminal in the system.

After the above steps are completed, this control ends.

In the above steps, any smart home node will make the same judgment and process when it receives the control command. This mechanism increases the robustness of the smart home network.

The above process describes how a smart home device establishes (or joins) an intelligent network system, and in this system, how an intelligent control terminal simultaneously controls a group of smart home nodes. The following describes the case where the smart terminal is a smart phone.

An example diagram of a smart home system is shown in Figure 5, the system includes a smart control terminal (smart phone) and 8 smart home nodes. Among them, the first, second and third smart home nodes are device members No. 1, No. 2 and No. 3 of the first group, and the group control addresses are 0101, 0102, 0103 respectively; the fourth, fifth and sixth smart home nodes They are members of device No. 1, No. 2 and No. 3 of the second group, and the group control addresses are 0201, 0202, and 0203 respectively; the seventh and eighth smart home nodes are members No. 1 and No. 2 of the third group, and the group control addresses are 0301, 0302 respectively.

The above grouping situations are all completed in step 104 in FIG. 1 , and the details will not be repeated here.

In the smart home system, all smart home nodes communicate with the smart phone directly or indirectly (through the forwarding of other devices).

When the user wants to turn on the fourth smart home node 0301, the smart phone sends a control command with the group control address 0301, and the node 0301 knows that the command is a control command sent to itself through the above judgment mechanism, so it responds accordingly. In this way, individual control of smart home nodes is realized.

When the user wants to turn on the fourth smart home node 0202 (not within the Bluetooth communication range of the smart phone), the smart phone sends a control command with a group control address of 0202, and other nodes receive the command and make the above judgment to know that it needs to forward This instruction, until the node 0202 receives the control instruction and responds. This enables individual control of smart home nodes that are not within the communication range of smartphones.

When the user wants to turn on all the smart home nodes of the second group, the smart phone sends a control command with a group control address of 0200, and the smart home nodes not in the second group forward the command after receiving the command, and the smart home nodes of the second group In addition to forwarding the command, the node also responds to the command. In this way, the whole group control of smart home nodes is realized.

It should be noted that, in this embodiment, the control terminal can be not only a smart phone, but also other smart devices supporting Bluetooth low power consumption, such as IPad, smart remote controller, and the like. Just install the corresponding APP on the smart device.

At the same time, it should be noted that one smart home node can store one or more group control addresses. For example, the second smart home node can have two group control addresses, which are: 0102 and 0204. In this way, when the second smart home node When a group-wide control command is received for the second group of devices, it will also respond to that command.

Those of ordinary skill in the art can understand that the above-mentioned embodiments are specific examples for realizing the present invention, and in practical applications, various changes can be made to it in form and details without departing from the spirit and spirit of the present invention. scope.
