Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 is a schematic flow chart of a master-slave working mode control method according to an embodiment of the present invention, and as shown in fig. 1, the master-slave working mode control method according to the embodiment of the present invention includes:
step S102, an input device in the wireless Mesh network receives communication packets carrying identification information sent by other input devices in the same wireless Mesh network, and sends the communication packets carrying identification information of the input device to other input devices;
step S104, analyzing the received communication packet to obtain identification information of other input equipment, and controlling the input equipment to work in a master mode or a slave mode based on the identification information of the input equipment and the identification information of the other input equipment; the input device confirmed as the master mode controls the lighting states of the Mesh lighting nodes in the wireless Mesh network, and the input device confirmed as the slave mode transmits the input information to the input device working in the master mode for unified processing.
Based on the master-slave working mode control method provided by the embodiment of the invention, the working mode of each input device can be determined through automatic negotiation in a wireless Mesh network comprising at least two input devices and a plurality of Mesh lighting nodes, and then the master input device and the slave input device are determined in the whole wireless Mesh network. The input device confirmed as the master mode controls the lighting states of the Mesh lighting nodes in the wireless Mesh network, and the input device confirmed as the slave mode transmits the input information to the input device working in the master mode for unified processing. The slave input equipment sends various input information detected by the slave input equipment to the master input equipment, and the master input equipment performs overall processing so as to control the working state of each lighting Mesh node in order without ambiguity. Further, the master-slave working mode control method provided by this embodiment can be implemented based on ad hoc network without adding a gateway or other third-party network devices.
The input device in the wireless Mesh network may be preferably a sensor, and the Mesh lighting node may be preferably a bluetooth Mesh lighting node, and certainly, in practical applications, the input device may also select other devices, and the Mesh lighting node may also be other Mesh nodes having a wireless connection function, which is not limited in the present invention.
In the embodiment of the invention, a plurality of input devices in the same wireless Mesh network can communicate with each other, and when any input device receives a communication packet carrying identification information and sent by other input devices, the communication packet carrying the identification information of the input device can also be sent to other input devices.
Optionally, in the above embodiment, the identification information of the input device in the wireless Mesh network may be machine code, internet address, or other identification information that can uniquely identify the input device. When the identification information of the input device is a machine code, the step S104 may include: analyzing the received communication packet to obtain machine codes of other input equipment in the wireless Mesh network; acquiring a machine code of the input device; and controlling the working mode of each input device through an arbitration algorithm based on the machine code of each input device in the wireless Mesh network.
The machine code is a series of sequences formed by a series of encryption and hashing of hardware serial numbers. In the above embodiment, each input device in the wireless Mesh network carries a unique machine code, so that other devices recognize information of each input device according to different machine codes. And the corresponding input equipment can be more accurately determined based on the unique machine code of each input equipment, so that the master equipment and the slave equipment in the wireless Mesh network can be effectively distinguished and determined.
Further, when the operating mode of one input device in the wireless Mesh system is controlled through the arbitration algorithm, the machine codes of all the input devices in the wireless Mesh network can be used for carrying out hash calculation, and the hash value of all the input devices in the wireless Mesh network is obtained through the hash algorithm. Since the machine code of the input device is unique, the hash value calculated based on the machine code is also unique. And sorting the hash values of the input devices obtained by calculation, then sequentially arranging the hash values to generate a hash value sequence, comparing other hash values in the hash value sequence of each input device, and judging the working mode of the input device according to the comparison result.
A hash algorithm is an algorithm that generates a hash value of some piece of data (e.g., a message or a session item). A good hashing algorithm has the property of altering the hash value result in accordance with variations in the input data. Thus, hashing works well to detect any changes in a large information object, such as a message. A good hashing algorithm makes it computationally infeasible to construct two independent inputs with identical hashes. Typical hashing algorithms include MD2, MD4, MD5, and SHA-1. And the hashing algorithm may also be referred to as a hashing function.
Calculating the hash value of the input device and the hash values of other input devices, and comparing the calculated hash values, wherein when the input device is the input device with the largest hash value in the wireless Mesh network, the input device can be controlled to work in a master mode, namely, the input device is used as the master input device in the wireless Mesh network; and when the input device is not the input device with the largest hash value in the wireless Mesh network, controlling the input device to work in a slave mode, namely, as the slave input device in the wireless Mesh network. After the working modes of all the input devices in the wireless Mesh network are determined, only one input device works in a master mode, and other input devices all work in slave modes. That is to say, after the operating mode of the input device is determined, the whole wireless Mesh network only has one main input device, so that when a control event occurs subsequently, the main input device and the slave device perform information synchronization, and ambiguity cannot occur.
After the operation mode of the input device is determined, if the input device operates in the master mode, the input device may be used as a master input device to control the lighting states of the multiple Mesh lighting nodes in the wireless Mesh system, such as the brightness, the color temperature, the color and the power-on state of the Mesh lighting nodes. Optionally, the master input device in the wireless Mesh system may collect input information of the slave input device, and control the lighting state of each Mesh lighting node in the wireless Mesh network according to a preset application logic. The input information from the input device may be user information detected by a sensor, environmental data information, and the like. The preset application logic may be a preset lighting instruction executed based on a triggering action of a user, for example, after someone triggers the infrared sensor, the lighting lamp needs to be turned on; the present invention may also be a preset combined lighting control for different application scenes, such as controlling the combined brightness of one or more Mesh lighting nodes, combining color matching, and the like, which is not limited in the present invention.
And if the input device works in the slave mode, the input device serves as the slave input device to transmit the input information of the input device to the input device working in the master mode, and the preset application logic controls the illumination state of each Mesh illumination node after the input information is collected by the input device working in the master mode.
In the embodiment of the invention, the master-slave input equipment in the wireless Mesh network does not need to be fixed, has strong adjustability, can be replaced by other modules or components, and has higher practicability. It should be noted that, in the foregoing embodiment, the communication between the input nodes may be a bluetooth chip with a wireless communication function, zigbee, or the like, and the specific logic operation may be processed by a logic device with a calculation function or other integrated chips with corresponding functions, which is not limited in the present invention.

2. the negotiation is only needed once, the communication back and forth is not needed, each input device can analyze the information in the packet after receiving the communication packets of other input devices, and then the input device arbitrates whether the input device needs to work in a slave mode or not through an algorithm;
3. when the negotiation is completed, only one input device in the network works in the master mode, and the other input devices work in the slave mode; the input device working in the slave mode needs to transmit the state to the input device working in the master mode, so that the subsequent master-slave synchronization is facilitated;
4. and judging the working mode of the input equipment, and if the input equipment works in the master mode, uniformly informing the collected transmission messages of the slave equipment to other Mesh nodes in the network by the input equipment working in the master mode according to preset application logic so as to realize the control of the illumination state of the Mesh nodes.

The input equipment is set as an infrared sensor, after the master-slave mode of each equipment is determined, the slave equipment informs the master equipment of the event when sensing that the area controlled by the slave equipment is unmanned, the master equipment performs overall logic processing on transmission messages of all other slave equipment, and then sends control commands to lamps in all areas to perform control actions.
