[0027] like Figures 1 to 10 As shown, the utility model provides a coal mine information guidance and release terminal system, including an information guidance and release terminal device, an underground intrinsically safe switch and a communication base station. The information guidance and release terminal device communicates with the ground core switch through the underground intrinsically safe switch (including Modbus gateway) and the communication base station (4G base station or 5G base station or a fusion base station of WiFi, 4G and 5G), thereby realizing wired and wireless Ethernet connection with the ground information center.

[0028] The information guidance and release terminal device includes a main control communication layer, an environmental perception layer and an information display layer. The main control communication layer is used to transmit data with the underground intrinsically safe switch and communication base station. The environmental perception layer is used to collect underground environmental information by connecting various environmental detection sensors. The information display layer is used to publish and display the collected environmental information and the information transmitted to the information guidance and release terminal device by the ground information center.

[0029] Specifically, the information guidance and release terminal device of the present invention displays information through a splicable LED display screen, wherein the splicable LED display screen is composed of multiple LED display panels, and a main control circuit board is installed in the LED display screen, and the main control circuit board integrates an MCU, a power module, a ground information center communication interface, an LED display panel communication interface and an information collection interface; wherein the MCU serves as the main control center, realizes communication and data transmission with each interface, and can process the data collected by each interface, and then judges abnormal information through a threshold value, displays it on the LED display panel, and can alarm through an audible and visual alarm connected to the main control circuit board.

[0030] The utility model expands the communication interface and functional modules on the basis of a splicable LED display screen to form a set of information guidance and release terminal devices with independent and complete functions, with a main control circuit board as the communication core, an LED display panel and an audible and visual alarm as information display components, and various sensors as environmental perception components.

[0031] The communication interfaces of the ground information center include RS485 interface, Ethernet interface, 4G / 5G interface and WiFi interface. The RS485 interface and WiFi interface back up each other and jointly undertake the tasks of transmitting original data and receiving data from the ground information center. The Ethernet interface and 4G / 5G interface back up each other and jointly undertake the task of receiving multimedia data streams from the ground information center.

[0032] The communication interface of the LED display panel is an independent RS485 interface, which is directly connected to the RS485 interfaces of several spliced ​​LED display panels to form a one-master-to-multiple-slave bus structure. The communication interface of the sound and light alarm is an independent RS485 interface, which is directly connected to the RS485 interface of the sound and light alarm.

[0033] The information acquisition interface includes an RS485 interface and several IO interfaces, wherein the RS485 interface is directly connected to the RS485 interface of the sensor to form a one-master-to-multiple-slave bus structure, and the IO interface is directly connected to the high and low level output ports of the sensor.

[0034] Sensors installed in the environmental sensing layer can be divided into sensors that monitor the underground environment, including but not limited to underground hazardous gas detection sensors (CO sensors, methane sensors, gas sensors, etc.), wind speed and pressure sensors, and water penetration detection sensors; and sensors that monitor underground operating equipment, including but not limited to infrared safety gratings, belt conveyor roller bearing temperature sensors, and belt conveyor roller bearing vibration sensors. The main control circuit board performs on-site data processing. If an environmental parameter anomaly is detected, it immediately sends a text, sound, light, and voice alarm through the LED display and sound and light alarm, ensuring underground safety.

[0035] The main control circuit board of the utility model provides a rich set of communication interfaces to achieve redundant and reliable connection with the ground information center. When one of the communication links fails, the other set of communication links is promptly activated to ensure that key information is reliably transmitted. In addition, the main control circuit board can not only receive data from the RS485 interface, but also receive IO point actions. Taking the infrared anti-beam safety grating as an example, the terminal device can detect on-site whether there is a vehicle entering the area demarcated by the safety grating, and remind the vehicle to evacuate or slow down through it through the sound and light alarm. As a functional expansion, the information collection interface can also have Bluetooth and LORA access capabilities, making it possible to access various sensors with wireless communication.
