And the wiring in the explosion-proof box is connected with the outside through a rubber glan wire inlet device. And an external power supply is connected to the inside of the system through an interface a to supply power to the whole system. The antenna of the 4G wireless communication module and the antenna of the WIFI module are connected to the outside of the system through an interface b, and a connection signal is provided for the 4G wireless communication module and the WIFI module. The CAN bus is outside through interface c system, and the CAN bus receives the data service that new forms of energy mine car provided. The audio and video input is connected to the inside of the system through an interface d, and the analog high-definition video receiver and the audio encoder provide audio and video input. The video output is received the system outside through interface d, for with the utility model discloses the explosion-proof display of connecting provides video information.

The MCU processor manages the charging process of the multiple groups of nickel-hydrogen battery packs. When the power supply voltage is suddenly lost, the nickel-metal hydride battery pack provided with the discharge mark discharges to replace the power supply voltage, so that the whole equipment can still normally work within a certain time. The MCU processor receives data provided by the new energy mine car through the CAN bus. The MPU processor receives data provided by the new energy mine car through the MCU processor, receives the states of the multiple groups of nickel-hydrogen battery packs through the MCU, receives audio and video information received and converted by the analog high-definition video receiver and the audio encoder through the audio and video interface, and receives acceleration data and angular velocity data through the gyroscope. And the MPU processor respectively sends the received and processed new energy mine car data, the states of the multiple groups of nickel-hydrogen battery packs, audio and video information, acceleration data and angular speed data to the monitoring center through the 4G wireless communication module or the WIFI module. If the 4G wireless communication module and the WIFI module are not connected with the monitoring center, the MPU processor stores the received and processed new energy mine car data, the states of the multiple groups of nickel-hydrogen battery packs, audio and video information, acceleration data and angular velocity data into the EMMC nonvolatile memory, and the data are reissued when the 4G wireless communication module or the WIFI module can be connected with the monitoring center.

As fig. 6, the MPU processor receives, stores, and transmits data processes are specifically described. The MCU processor manages the charging process of the multiple groups of nickel-hydrogen battery packs. The MCU processor receives data provided by the new energy mine car through the CAN bus. The MPU processor receives data provided by the new energy mine car through the MCU processor, receives the states of the multiple groups of nickel-hydrogen battery packs through the MCU, receives audio and video information received and converted by the analog high-definition video receiver and the audio encoder through the audio and video interface, and receives acceleration data and angular velocity data through the gyroscope. When the 4G wireless communication module and the WIFI module are not normally connected with the monitoring center, the MPU processor stores the received and processed new energy mine car data, the states of the multiple groups of nickel-hydrogen battery packs, the audio and video information, the acceleration data and the angular velocity data into an EMMC nonvolatile memory. When the 4G wireless communication module or the WIFI module is normally connected with the monitoring center, the MPU processor sends the received and processed new energy mine car data, the states of the multiple groups of nickel-hydrogen battery packs, audio and video information, acceleration data and angular velocity data to the monitoring center, inquires whether data stored in the EMMC nonvolatile memory before exists or not, and if yes, deletes the data from the EMMC nonvolatile memory after the completion of data reissue.

Referring to fig. 7, the charging process of the multiple groups of nickel-metal hydride batteries managed by the MCU processor is specifically described. After the device is started, the MPU processor reads information from the EMMC to confirm the discharging nickel-metal hydride battery pack before power failure and sends the information to the MCU processor. The MCU processor sets a discharging mark on the group of nickel-hydrogen battery packs, and the power state mark is a power supply. Every 1 second, the MCU processor reads the power supply voltage and all the nickel-hydrogen battery pack voltages. When the current power supply voltage value is greater than 11.5V, the power supply voltage is normal, and the MCU effectively manages and adjusts the process of charging and discharging the nickel-hydrogen battery pack. When the current power supply voltage value is less than 11.5V, the MCU processor sends the currently discharged nickel-metal hydride battery pack information and the current power supply voltage value to the MPU processor, and the MPU processor writes the discharged nickel-metal hydride battery pack information into the EMMC, and sends a power supply voltage value through 4G to indicate that the external voltage is under-voltage, and then the equipment is turned off.

Referring to fig. 8, the MCU in fig. 7 will effectively manage and adjust the process of charging and discharging the nickel-metal hydride battery pack. When the voltage value of the currently discharged nickel-metal hydride battery pack is less than 3.6V, the MCU processor sets a discharge mark for the nickel-metal hydride battery pack which is not marked as charged and has the highest voltage. If the nickel-metal hydride battery pack is not marked as a charging nickel-metal hydride battery pack, or the voltage value of the nickel-metal hydride battery pack provided with the charging mark is 5.1V, the MCU processor sets the charging mark for the nickel-metal hydride battery pack which has the lowest voltage and is not marked as a discharging nickel-metal hydride battery pack.
