[0052] Before detailing the specific embodiments of the technical solution of this application, we will first disclose the application scenarios suitable for supporting the lighting control method for implementing the architecture and safe production in the technical solution of this application.

[0053] The technical solution of the present application is applicable to the field of safety production technology, especially to the lighting control and safety management scene under the production workshop. In this context, the technical solution of the present application can be applied in a typical Bluetooth mesh network system, as shown in Figure 1 and Figure 2 The system includes node networking 200, Mesh Bluetooth network 500, cloud platform end 600 and application end 700.

[0054] Among them, the node networking 200 includes a plurality of lighting devices 100 as relay nodes for message broadcasting within the node networking to achieve internal flooding broadcast, wherein each lighting device 100 as a relay node has the function of a message amplifier, until the message within the networking is broadcast to all lighting devices 100 as nodes.

[0055] Specifically, the Mesh network 500 includes node networking 200, proxy node 300 and intelligent gateway 400, wherein the proxy node 300 is used to convert the data format of non-Mesh Bluetooth protocol (such as GATT format) into the Mesh data format of local device interaction, and the data conversion of the proxy node also includes direct communication between the application end 700 and the node networking 200, and the intelligent gateway 400 is used to solve the communication protocol difference and convert the data in the Mesh network into a format recognizable by the cloud platform end and the application end.

[0056] Specifically, the lighting device 100 includes a control unit 110, a communication unit 120, a luminaire 130, a radar sensing unit 140, a flame sensing unit 150 and a light sensing unit 160, wherein the communication unit 120 is used for communication of the lighting device 100 within the node networking 200, the luminaire 130 is used to provide lighting function in the node area, the radar sensing unit 140 is used to detect the trajectory of personnel activity and other object activity in the node area as a trigger basis for judging whether to control lighting, the flame sensing unit 150 is used to monitor whether there is fire in the node area, and the light sensing unit 160 is used to detect the brightness in the node area to control the PWM automatic brightness dimming through the control unit 110. It can be understood that the energy consumption sensor (not shown in the figure) is usually built-in in the lighting device 100 to monitor the energy consumption of the local lighting device 100, and the energy consumption of all lighting devices 100 is calculated through the lighting control system shown in the present application, so as to optimize the energy consumption control of all lighting devices 100 in the production workshop environment.

[0057] In the prior art, with the gradual transformation of traditional factories into intelligent development, the application environment and functional requirements of the lighting system are increasingly complex, and the timing lighting control relying on preset switch time cannot meet the demand of intelligent dimming, especially in the production workshop, the production process of precision operation has higher demand for dynamic softness of lighting.

[0058] At present, most of the lighting areas and lighting brightness of the lighting device are fixedly set, and the lighting cannot be adaptively adjusted according to production activities and environmental perception, wherein the light energy converted from electric energy is not effectively utilized, which not only cannot meet the production lighting demand, but also has low energy-saving efficiency;

[0059] Secondly, the lighting device without data management has the problem of difficult maintenance, and is seriously dependent on manual inspection to monitor the lighting state, resulting in low optimization efficiency of energy efficiency management.

[0060] Finally, the safety monitoring device (such as a fire warning device) is usually arranged sporadically in the production workshop, and cannot cover the entire production area, especially when unattended, the reliability of safety warning is particularly important for safety production.

[0061] Further, in order to solve the above technical problems, the present application provides a safety production lighting control method, which aims to meet the production scene demand of adaptive lighting energy efficiency adjustment and safety warning.

[0062] The technical solutions of the embodiments of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments.

[0063] The specific embodiments below can be combined with each other, and the same or similar concepts or processes will not be described again in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0064] Referring to Figure 3 The present application discloses a safety production lighting control method, and in its typical safety production embodiment, the method comprises the following steps:

[0065] 1100, each lighting device is configured as a node to build a Mesh network, and bidirectional communication between the Mesh network and a terminal is established, wherein the terminal includes a cloud platform end and an application end;

[0066] Optionally, the cloud platform end can include a cloud platform constructed by a server with edge computing function and data storage function, and the application end can be a Web management platform or a mobile device, wherein the Web management platform sets the function strategy through a computer device, and the mobile device sets the function strategy through an APP program. The application end can directly communicate with the node group network composed of various lighting devices in the Mesh network through a proxy node, or can be controlled by the cloud platform end issuing instructions. The application end is mainly used for function strategy generation, and the cloud platform end can be used for function strategy storage and optimization. It can be understood that the application end can directly send function instructions to any single lighting device for lighting control or security warning control, or can send function instructions to multiple lighting devices in a node area for lighting control or security warning control. Each lighting device will be confirmed according to the floor position, area position and installation position of the lighting device when it is connected to the network.

[0067] In a specific embodiment, each lighting device as a node is configured to connect to the network to build a Mesh network, including the following steps:

[0068] Each lighting device is configured to connect to the network through the application program of the terminal, and the network connection configuration includes key exchange, address allocation and security configuration;

[0069] Each lighting device in the Mesh network is configured with node functions, including at least one of the publishing function, the subscription function or the relay function;

[0070] The publishing function, each lighting device as a node, sends a message to a target multicast address, and the message includes one of sensing data, function instructions or encapsulated broadcast packets;

[0071] The subscription function, each lighting device as a node is configured to listen to the message sent to the target multicast address;

[0072] The relay function, each lighting device as a node listens to all messages in the Mesh network, judges whether it is a target lighting device based on the multicast address and TTL value contained in the message, if yes, parses the message, if not, broadcasts the message to other nodes after updating the TTL value.

[0073] Among them, the user can connect each lighting device in the production workshop to the network through the mobile terminal application program during the lighting device network connection process, which is convenient for centralized management of all lighting devices.

[0074] In the networking process, the publishing function of each lighting device can make any lighting device send messages to a specific local multicast address, for example, when lighting device A receives a broadcast packet with multicast address 224.0.0.1, lighting device A can directly forward the broadcast packet to the multicast address, or lighting device A can send a lighting control broadcast packet to the address corresponding to lighting device B, so as to achieve wider coverage and scalability.

[0075] In the networking process, the subscription function of each lighting device can make any lighting device accurately receive the broadcast packet of the function instruction to be executed, which can further expand the coverage of the broadcast message, for example, after the proxy node sends the encapsulated broadcast packet, the lighting device can listen to receive the encapsulated broadcast packet, while realizing the effect of decentralization, making the Mesh network more robust.

[0076] In the networking process, the relay function of each lighting device can make any lighting device capture broadcast information, and all lighting devices can act as relay nodes to rebroadcast the received broadcast information. Specifically, the number of broadcast forwarding can be determined according to the TTL value. If the TTL value is greater than 1 and the target address is not the lighting device, the TTL value is reduced by 1 and the broadcast is continued until the broadcast packet is sent to the target address of the target lighting device. Through relay signals, it can be transmitted very far, far beyond the range of a single Bluetooth device, cover more devices and have a wider range.

[0077] It can be understood that the node transmission topology between all lighting devices as nodes in the present application is not based on fixed parent-child relationship, but based on flooding broadcast. Messages spread like water waves, and each lighting device as a relay node is an amplifier, thereby expanding the network range. Through publishing, subscribing and relaying, efficient and flexible group control is realized, in which different nodes perform their respective functions, thereby optimizing network performance and power consumption.

[0078] In an optional embodiment, the bidirectional communication between the Mesh network and the terminal is established, including the following steps:

[0079] The Mesh network communicates through the built-in intelligent gateway bridge terminal, wherein the Mesh network converts, encapsulates and broadcasts non-Mesh messages through the proxy node, and / or establishes a communication connection between the application end of the non-Mesh device and the Mesh network through the proxy node.

[0080] Specifically, the Mesh network only supports the Mesh protocol format, and based on the communication requirements between the Mesh network and the terminal, non-Mesh messages need to be converted. For example, after setting the automatic dimming function strategy through the application end, the cloud platform server sends instructions to the intelligent gateway through the communication network (such as the Internet), and the intelligent gateway sends the function instructions of the GATT protocol to the proxy node to convert them into Mesh protocol and encapsulate them as broadcast packets for broadcasting within the node networking.

[0081] 2100、Mesh network obtains the sensing data in the node area through the sensor built-in the lighting device, and uploads the sensing data to the terminal;

[0082] In an optional embodiment, the Mesh network obtains the sensing data in the node area through the sensor built-in the lighting device, and uploads the sensing data to the terminal, including the following steps:

[0083] The lighting device corresponding to each node in the Mesh network obtains the sensing data at the current time through the sensor, and the sensor includes an illumination sensor, a flame sensor, a millimeter wave radar, and an energy consumption sensor;

[0084] The lighting device of each node encapsulates the sensing data as a broadcast packet with the proxy node as the target address and broadcasts it to other nodes according to the preset condition triggering the reporting mechanism, until the proxy node receives the sensing data and uploads it to the terminal.

[0085] Optionally, the sensing data can be the illumination brightness collected by the illumination sensor in the node area, the fire detection data collected by the flame sensor in the node area, the moving track of personnel or objects detected by the millimeter wave radar in the node area, and the energy consumption of the lighting device in a period detected by the energy consumption sensor. For example, the user can use a mobile device to view the running state and area state of the lighting device in any node area in the current networking in real time, which facilitates real-time regulation and control. It can be understood that the sensing data is mainly used to provide data support for the function strategy of the application end, so as to feedback to the lighting device in real time to execute the corresponding function instruction.

[0086] Optionally, the node encapsulates the monitored state and energy data as a broadcast packet and actively broadcasts it through triggering and timing mode. Other nodes receive the broadcast packet and perform analysis and verification to determine whether the address is itself. If not, the message is broadcasted again until it is uploaded to the proxy node and then uploaded to the cloud platform through the intelligent gateway.

[0087] Optionally, in addition to uploading the sensing data to the terminal, the lighting device can also broadcast the sensing data among the adjacent nodes in the network, thereby achieving precise adjustment of the lighting to achieve the purpose of adaptive control. It can be understood that the lighting device is pre-set with an automatic control lighting control strategy, and the adjustment data provided by the light sensor and the millimeter wave radar is automatically adjusted by PWM.

[0088] 3100、The terminal pre-sets the first function strategy of the target lighting device, generates a function instruction corresponding to the second function strategy based on the received sensing data, and issues the function instruction to the Mesh network, wherein the function instruction includes at least one of lighting control or safety warning;

[0089] In a specific embodiment, the terminal pre-sets the first function strategy of the lighting device, generates a function instruction corresponding to the second function strategy based on the received sensing data, including the following steps:

[0090] The first function strategy of the lighting device is set according to the production needs of the node area, and the function strategy includes at least one of brightness adjustment, energy consumption adjustment, activity sensing, or safety monitoring;

[0091] The terminal receives the sensing data, determines the adjustment parameter of the lighting control based on the real-time brightness and the target activity trajectory in the node area in the sensing data, and determines the warning parameter based on the safety monitoring value in the sensing data, and combines the adjustment parameter and the warning parameter to generate a function instruction adjusted from the first function strategy to the second function strategy, wherein the warning parameter simultaneously acts on the terminal for safety warning, and the function instruction is provided with a multicast address of the corresponding node according to the target lighting device object of the node area.

[0092] Optionally, each lighting device is usually set with corresponding brightness, energy consumption threshold, activity sensing task and safety monitoring task by the application terminal during working hours, wherein the activity sensing task is used to identify the moving trajectory of personnel activity or object activity in the production workshop, such as Figures 5-6 As shown, when the node A sensor detects the trajectory of personnel or specified volume of goods activity, it will actively respond to the adjacent nodes B, D, E, etc. to send trajectory data, and the nodes B, D, E automatically calculate the distance data and control the brightness of the lamps and lanterns through PWM. After the trajectory weakens or disappears, it automatically returns to the automatic strategy state.

[0093] Further, each lighting device as a node can be marked with the floor or area position of the installation, and after the lighting device networking is completed, a monitoring area is formed below, such as Figure 7As shown, the dotted line area is the detection range of the flame sensor. When an open flame appears within the detection range and is detected by the sensor, it will actively trigger the lighting equipment node to report the fire data. After being processed by the server on the cloud platform, the application on the application device will notify relevant personnel to handle the safety alarm via APP or SMS. Especially in terms of safe production, it enables intelligent networking of fire control areas for timely monitoring and response.

[0094] 4100. In a Mesh network, a first node receives an encapsulated broadcast packet containing functional instructions. The encapsulated broadcast packet is a broadcast packet sent by a proxy node and / or a second node that has received the encapsulated broadcast packet. Based on the multicast address preset by the node, at least one target lighting device is determined from the first node and the second node to execute the functional instructions.

[0095] In one specific embodiment, the first node in the Mesh network receives an encapsulated broadcast packet containing functional instructions, specifically:

[0096] The terminal sends a function instruction to the smart gateway according to the second function strategy. The function instruction is encapsulated into a broadcast packet by the proxy node and broadcast to the Mesh network.

[0097] Within the Mesh network, each node continuously listens for internal network messages until it receives an encapsulated broadcast packet. The node parses the encapsulated broadcast packet to confirm whether the address is its own. If it is, the node is confirmed as the first node; otherwise, the node becomes the second node and continues to broadcast the encapsulated broadcast packet to other nodes.

[0098] In one specific embodiment, based on the multicast address preset by the node, at least one target lighting device is determined from the first node and the second node to execute the functional instruction, specifically as follows:

[0099] Based on the detected target activity trajectory, the multicast address of the target lighting device within the node area is determined, wherein adjacent nodes send activity trajectory data to each other according to the nearest neighbor algorithm;

[0100] Based on the activity trajectory data within the node area, the lighting adjustment parameters of any target lighting device under the current trajectory are calculated, and the target lighting devices in the first node and the second node execute lighting control sequentially according to the function instructions.

[0101] Furthermore, for each node, a region location is marked. When the safety monitoring value of the target lighting device is greater than the warning value, the region location marked in the packet and the monitoring value of that region location are broadcast to other nodes until the terminal receives the packet and performs the warning operation.

[0102] Specifically, the workflow of the lighting control method in the application is as follows: through the web platform or the mobile phone APP, the automatic lighting control strategy is set, the server automatically issues instructions to the intelligent gateway, the instructions are encapsulated into broadcast packets by the proxy node, and the broadcast packets are propagated to several nodes nearby, the nearby nodes listen to all messages in the network, and after receiving the broadcast packets, the broadcast packets are parsed and verified to determine whether the destination is itself, otherwise the message is broadcasted again. If the current destination is correct, the corresponding instruction operation is performed, such as turning on or off the light, adjusting the brightness, etc.

[0103] Further, the node encapsulates the monitored state and power data into a broadcast packet through triggering and timing mode, and actively broadcasts it. After other nodes receive the broadcast packet, they parse and verify it to determine whether the destination is itself, otherwise the message is broadcasted again. Until uploaded to the proxy node, the information data of the lighting equipment in the node area is uploaded to the network platform through the intelligent gateway, so as to realize real-time reporting of the information data of the lighting equipment in the node area.

[0104] Further, the lighting devices between adjacent nodes transmit trajectory data to nodes B, D, E, etc. through the near neighbor algorithm. Node B, D, E automatically calculates distance data and controls the brightness of the lamp through PWM. When the trajectory weakens or disappears, it automatically returns to the automatic strategy state.

[0105] Finally, the lighting device monitors and identifies the ignition point of the node area according to the marked installation position, so as to cover the entire production workshop. Compared with the sporadic arrangement of traditional case monitoring equipment, the flame sensor is set in the lighting device, which can increase the coverage of monitoring, especially when unattended, it can quickly respond and provide alarm information, thereby improving the reliability of safety warning and achieving the purpose of safe production.

[0106] Finally, the unique technical advantage of the present application is that the present application establishes the node networking of the lighting device through the Mesh network, realizes the mutual data forwarding between the devices through the broadcast and relay mode, does not need to be directly connected, and further realizes the cooperative switching, dynamic dimming and safety state monitoring of the lighting device through the function strategy. According to the personnel activity, natural light, production rhythm, the brightness is dynamically adjusted, not only can maintain the stability of the environment light, reduce the visual impact of the production personnel caused by the frequency flash, but also can optimize the energy consumption of the lighting lamp, so as to realize the adaptive lighting energy efficiency adjustment of the production workshop, and each lighting device under the Mesh network achieves the effect of decentralization, there is no single fault point to make the network more robust, at the same time, the network configuration is simple, which can expand more number of devices, and there is no need to worry about the influence of the increase of the number of devices on the message transmission. The transmissible range of the relay signal is wide, and the multi-to-multi communication mode is especially suitable for the group control and linkage scene of the Internet of Things in the production workshop, and has high application prospect.

[0107] Please refer to Figure 4 According to one aspect of the present application, a safety production lighting control device is provided, the device comprises:

[0108] A networking communication module is configured to configure each lighting device as a node to build a Mesh network, and establish bidirectional communication between the Mesh network and a terminal, wherein the terminal includes a cloud platform end and an application end.
