In addition, the monitoring board main body 1 is provided with a plurality of external interfaces on the front panel side and the back panel side of the vehicle-mounted monitoring board, for example, an external serial port 15, an external USB interface 21, and an Ethernet interface 12. These external interfaces are arranged on the surface of the shell 20 and are used for providing external connection for each module inside the shell 20 to realize data communication and data transmission.

[0030] Continuously referring to Figure 1 The CPU module 4, the RTC module 5, the FT232 module 6, and the SD card 7 are arranged in the circuit board of the monitoring board main body 1 when designed, the circuit board is integrated inside the shell 20, and the shape of the shell 20 is generally a hexahedron, thereby constituting the monitoring board main body 1. The front panel side and the back panel side of the vehicle-mounted monitoring board are any two corresponding sides of the hexahedron of the shell 20 of the monitoring board main body 1.

[0031] The CPU module 4 can receive the vehicle-mounted data of the monitoring ATC in real time and process it in time in the running process. The FT232 module 6 is connected with the CPU module 4 through a universal asynchronous receiver / transmitter 8, which is used for converting a Universal Serial Bus (USB) interface into a transistor-transistor logic (TTL) level universal asynchronous receiver / transmitter (UART) serial port to realize data communication.

[0032] The RTC module 5 is connected with the CPU module 4 through the integrated circuit bus 9, and the RTC module 5 is an electronic device for measuring time, that is, a real-time clock, specifically a clock chip, which can realize rapid early warning in time after receiving the vehicle-mounted data processed by the CPU module 4, and realize real-time alarm through the LED lamp installed on the LED lamp site 3, so as to facilitate the train staff to understand the fault alarm situation in real time.

And the setting position of the Ethernet interface 12 is on the rear backplate side of the vehicle-mounted monitoring board, which can not be disturbed by human, and ensures the stability of the network line connection, and the Ethernet interface 12 provides network resources for the CPU module 4, realizes network communication, and is used for the train staff to know the running state of the vehicle-mounted monitoring board.

[0036] In some embodiments, as shown in Figure 1 , the FT232 module 6 is further provided with an external serial port 15 on the front panel side of the vehicle-mounted monitoring board. The FT232 module 6 is designed by RS232 circuit, and can be specifically an FT232 chip or an FT232 converter, which mainly provides the external serial port 15 for the CPU module 4, and correspondingly, the FT232 module 6 is on the front panel side of the vehicle-mounted monitoring board, so as to facilitate the train staff to operate. In addition, the external serial port 15 can also be used for debugging the serial port of the CPU module 4 through the FT232 module 6, so as to timely know the equipment running state of the CPU module 4 and timely find possible hardware faults.

[0037] In some embodiments, as shown in Figure 1 The backup power supply 16 is also connected in the circuit of the monitoring board body 1, which can be a battery or a small power storage device, and is used to supply power to the monitoring board body 1 for a short time in case the power module 2 fails or cannot supply power to the monitoring board body 1 due to unexpected situations, so as to ensure that the modules in the monitoring board body 1 can maintain normal operation for a short time, so that the monitoring board body 1 has a certain power failure protection function and is not affected by sudden power failure, and can effectively avoid SD card damage caused by sudden power failure.

[0038] Further, the control switch 17 is also arranged on the front panel side of the vehicle-mounted monitoring board, and the control switch 17 is electrically connected with the monitoring board body 1. The power supply of the power module 2 can be controlled through the control switch 17, and in an unexpected situation, the power supply of the power module 2 can be cut off in time, so that the vehicle-mounted monitoring board is in a power-off state, and further accidents can be avoided.

[0039] In some embodiments, an isolation power module 18 is also arranged on the back panel side of the vehicle-mounted monitoring board, and the isolation power module 18 is electrically connected with the monitoring board body 1. The isolation power module 18 and the power module 2 are both provided with voltage converters, the voltage converted by the isolation power module 18 is greater than the voltage converted by the power module 2, and the output power of the isolation power module 18 is greater than the output power of the power module 2.

[0040] The voltage input into the vehicle-mounted monitoring board is generally 12V, and after the 12V voltage is input into the power module 2, the 12V voltage is converted into 3.3V voltage through the voltage converter, and then used to supply power to each module of the monitoring board body 1. The isolation power module 18 additionally arranged on the basis of the power module 2 is also provided with a voltage converter, which can convert 12V voltage into 5V voltage, and then also used to supply power to each module of the monitoring board body 1. Moreover, the output power of the isolation power module 18 is greater than the output power of the power module 2, and the output power of the isolation power module 18 is generally 15W, while the output power of the power module 2 is 10W. The type of the isolation power module 18 and the type of the power module 2 can be the same, for example, both can be a battery, a battery panel or a power storage device, etc.

[0041] In general, the monitoring board main body 1 is generally powered by the power module 2, and the isolation power module 18 is in an off state, and the power module 2 and the isolation power module 18 are arranged, on the one hand, when one of the power modules fails or cannot supply power, the other can be started to run and supply power in time. On the other hand, it can meet the different needs of the vehicle-mounted monitoring board. When the ATC is running, the vehicle-mounted monitoring board modules are running at full capacity, and the energy consumption of vehicle data analysis and data transmission is large. At this time, high voltage is needed for power supply, so the isolation power module 18 is started to help power supply and provide high power to ensure that the vehicle-mounted monitoring board runs normally under high load. When the ATC stops running, the efficiency of the vehicle-mounted monitoring board modules is reduced, and at this time only low voltage is needed for power supply, so the power module 2 is used for power supply to ensure that the vehicle-mounted monitoring board continuously operates at low power and maintains the monitoring function.

[0042] In some embodiments, the monitoring board main body 1 further comprises a storage module 19 connected with the CPU module 4 through the SDIO interface 11. The storage module 19 can be a large storage device board provided with a plurality of SD card ports, and the SD card 7 can be inserted into the corresponding SD card port. By designing the storage module 19, the number of SD cards 7 can be set according to the data capacity requirement, and the data storage capacity of the vehicle-mounted monitoring board is increased to monitor and store more vehicle data.

[0043] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
