Detailed Implementation
[0022] See Figures 1-4 As shown, the technical solution adopted in this specific embodiment is as follows: It includes a main light module 1, a secondary light module 2, and a host computer platform 3. The main light module 1, the secondary light module 2, and the host computer platform 3 are connected wirelessly. At least one main light module 1 is provided. The lamps used in both the main light module and the secondary light module are intrinsically safe explosion-proof lamps. A gateway 11 is provided in the main light module 1, and a main wireless communication module 12 is provided in the gateway 11. Both the main light module 1 and the secondary light module 2 are provided with a data acquisition module 4. In this embodiment, the main light module is the main processing module, which is provided with a gateway unit as a node connecting the secondary light modules. The data transmitted by the secondary light modules undergoes protocol conversion, data aggregation, and edge computing in the main light module, and is communicated with the host computer. The platform establishes a wireless connection, and both the main and secondary light modules are equipped with data acquisition modules, enabling real-time collection of environmental data within the mine tunnel. Specific processing programs can be set within the main light module, such as sending early warning signals or power outage signals, allowing for timely safety intervention and improving mine production safety. Through the collaborative work of the main light module, secondary light module, gateway unit, and host computer platform, the system achieves real-time monitoring of multiple parameters of the mine environment, intelligent lighting control, and early warning of safety hazards. The multi-sensor fusion technology and edge computing architecture offer high reliability, low power consumption, and strong anti-interference capabilities, making it suitable for safety management in complex mine environments. This allows the system to be used not only in mine production but also in large-scale explosion-proof areas, enhancing its practicality.
[0023] More specifically, the main wireless communication module 12 is a dual-band wireless communication module, including a WIFI module and a 4G module. More specifically, the secondary light module 2 is equipped with a secondary wireless communication module 21, which is either a WIFI wireless communication module or a LoRa wireless communication module based on ESP32, forming a LoRa self-organizing network node and a WIFI self-organizing network node. In this embodiment, a hybrid communication protocol LoRa / Wi-Fi 6 is used, with adaptive switching between the dual bands. Data transmission is also performed via the 4G communication module when needed. The LoRa module can be a 255 LoRa module. The MESH self-organizing network module operates in the 433MHz to 433MHz frequency band with a transmit power of 22dBm. It periodically uploads environmental data to the host computer platform. The Wi-Fi 6 module uses the ESP32-C6, supports MIMO technology, and has a bandwidth of 1.8GHz for real-time control command transmission. The maximum communication distance between the two LoRa modules is 3KM, making this system well-suited for large-scale scenarios. The Wi-Fi 6 module is better for sending short-range control commands with faster response times. The integration of the 4G communication module ensures effective data transmission and command control even in case of unforeseen circumstances. Furthermore, the LoRa module of the secondary light has a relay function, enabling it to receive information from other secondary lights. The signal is forwarded to other LoRa modules within its coverage area, significantly expanding communication and overall coverage. The main light module acts as a node to receive signals from the secondary light modules, and the secondary light modules act as relay nodes to receive information from the secondary lights within their coverage area. The main light module then uploads all the light information to the host computer platform. This not only greatly expands the communication coverage area but also enables intelligent control of all lights. The topology diagram formed by the main light module and the secondary light modules through the network can be clearly seen on the external visualization device of the host computer platform. The main light module is the gateway node G, and the secondary light modules are the secondary nodes N. The topology diagram clearly shows the specific situation of all lights, making intelligent control and management easier.
[0024] More specifically, the data acquisition module 4 includes a light sensor 41, an environmental parameter acquisition sensor 42, and a motion detection sensor 43. The environmental parameter acquisition sensor 42 includes a temperature and humidity sensor and a CO / O2 gas sensor. The temperature and humidity sensor and the CO / O2 gas sensor share a sampling channel and acquire data in a time-division manner through a multiplexer switch. In this embodiment, the temperature and humidity sensor is an SHT35 with an accuracy of ±0.5℃, which can effectively detect the temperature and humidity in the scene environment.
[0025] The CO / O2 gas sensor uses the MQ-2 / MQ-135, with a detection range of 0-1000ppm. It can effectively detect the content of methane gas in the mine, so that it can detect and warn of gas leaks in a timely manner, and take correct measures to prevent safety accidents and improve production safety.
[0026] The light intensity sensor uses the TSL2591, with a range of 0-100k lux, which can effectively detect personnel working in the scene. Especially in the event of an accident, it can better understand the situation of personnel in the area, promptly arrange personnel evacuation, and carry out subsequent rescue work, further improving the safety of the production environment.
[0027] More specifically, the gateway 11 is equipped with a protocol conversion interface, a local storage unit, and an edge computing unit. The gateway 11 also contains a LoRa self-organizing gateway module and a WIFI gateway module. In this embodiment, the main light module contains a gateway unit with a protocol conversion interface, a local storage unit, and an edge computing unit. The protocol conversion interface uses an STM32F407, supporting the mutual conversion of multiple application protocols to enable the host computer platform to interface with sensors of different interfaces and methods for light control, power acquisition, etc. The local storage unit (EEPROM) can store real-time collected data. The edge computing unit is used for lightweight analysis of the gas diffusion model. Since at least one main light module is set, the specific number can be set according to the actual scenario, which is beneficial for the specific control of secondary light modules and the construction of different control system networks.
[0028] More specifically, the main light module 1 and the secondary light module 2 are also equipped with a power metering unit 13, which can measure the power consumption in real time, which is more conducive to energy-saving control.
[0029] More specifically, the main light module 1 is also equipped with a data processing unit 14 based on an ARM Cortex-M3 microcontroller, which not only has a fast processing speed but also lower power consumption.
[0030] More specifically, both the main light module 1 and the secondary light module 2 are equipped with a PWM dimming-based drive circuit. By setting up the PWM dimming-based drive circuit, the light can be better adjusted and controlled according to the light data acquisition, thereby preventing the waste of power resources.
[0031] More specifically, the host computer platform 3 is equipped with a host computer wireless communication module 31, which includes a Wi-Fi 6, a 4G wireless network module, and an Ethernet module. The Ethernet module is a reserved backup module. It communicates with the main lamp module through Wi-Fi 6 or 4G. The host computer platform includes a data layer, an application layer, and a control logic layer. The data layer uses InfluxDB to store time series data and MQTT Broker (Mosquitto) to manage device connections. The application layer adopts a three-dimensional visualization engine: based on WebGL to render the mine tunnel model and mark the device status (normal / fault / offline).
[0032] Intelligent Analysis Module: CO Diffusion Simulation: Predicts hazardous areas using cellular automata algorithm; Control logic includes an automatic dimming strategy: Dynamically adjusts LED brightness based on light sensor data (PID algorithm);
[0033] Emergency evacuation route planning: The optimal route is generated by combining personnel positioning data. The multi-level control system built by the host computer platform in conjunction with the main light module and the secondary light module greatly improves the response speed of system control and also enhances production safety.
[0034] The working principle of this utility model is as follows: The main light module 1 is installed from the mine tunnel exit inwards. The number of main light modules 1 is determined according to the overall scale of the mine tunnel. Secondary light modules 2 are installed equidistantly between the two main light modules 1 along the mine tunnel. The secondary light modules 2 establish a wireless signal connection with the main wireless communication module 12 of the main light modules 1 through a secondary wireless communication module 21. The main light modules 1 then establish a wireless connection with the host computer platform 3, thereby realizing the network construction of the entire mine tunnel lighting system and forming a control system capable of real-time data acquisition and monitoring. In operation, the light sensor 41 transmits light change data to the main light module 1 via the wireless network and uploads it to the host computer platform 3. The processing system within the main light module 1 adjusts the light brightness according to the light changes. The system utilizes electricity resources rationally and prevents waste. Environmental parameter acquisition sensor 42 monitors the working environment, such as temperature, humidity, and CO / O2 gas levels. When values exceed safe limits, the host computer platform 3 will issue an alarm and can be set with specific protection modes to cut off power under certain circumstances to prevent gas explosions. Motion detection sensor 43 can detect moving objects in the work area, especially workers, and can promptly upload personnel location information in case of an accident to facilitate evacuation and rescue. Through the multi-layered network setup of LoRa and Wi-Fi 6 modules, the mine lamp system becomes a real-time adjustable production environment safety monitoring system, greatly improving the safety of mine production.
