[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0023] Please refer to Figure 1 The train-mounted communication device provided in the embodiment comprises a bus, a control module, a train positioning module, a power module, a signal processing module and a communication connection module, wherein:

[0024] The bus is connected with the signal transceiving port of the communication connection module and the control module respectively; the power module is connected with the power input end of the control module; the first signal output end of the control module is connected with the first signal input end of the communication connection module, the second signal output end / input end of the control module is connected with the signal output end / input end of the train positioning module, and the third signal output end / input end of the control module is connected with the first signal output end / input end of the signal processing module; the second signal output end / input end of the signal processing module is connected with the second signal output end / input end of the communication connection module.

[0025] As shown in Figure 2 The combination of the MCU module and the UART module can form a control module with high integration, flexibility, reliability and low cost. The MCU module can control logic algorithm or data processing algorithm according to the specific requirements of train communication. The UART module provides an additional serial port, which can expand the train-mounted communication device and support more communication links or devices, thereby providing stable signal control and transceiving functions, especially suitable for electrically isolated environments and improving the anti-interference ability of the train-mounted communication device.

[0026] The UART module adopts a UART008 3U CompactPCI 8 serial port board; and the UART008 3U CompactPCI 8 serial port board is connected with the bus.

[0027] The UART008 3U CompactPCI 8 serial port board adopts RS232, RS422 and RS48 serial communication protocols to connect with the bus. The electrical isolation provided by the UART008 enhances the anti-interference ability of the system and improves the stability of the communication. The interfaces of the UART008 3U CompactPCI 8 serial port board and the corresponding connection relationship comply with the corresponding user manual.

[0028] The communication connection module includes a train-train communication submodule and a train-control station submodule in parallel. The train-train communication submodule adopts wireless communication technology to connect with the bus. The train-control station submodule adopts wireless communication technology or Ethernet to connect with the bus. Since the distance between the train and the control station gradually increases as the train runs, wireless communication technology is more suitable. If the running route of the train is short, Ethernet is more suitable for data transmission.

[0029] When the train performs any one or both of train-train and train-control station communication, the communication connection can be performed through the train-train communication submodule or / and the train-control station submodule. When the train needs to receive the on-board information inside the train or the status information of the trackside equipment, the front panel or the rear panel of the UART008 3U CompactPCI 8 serial port board is used for signal transceiving. For different data types, different modules are used for receiving or transmitting, which can optimize the efficiency and reliability of data transmission, reduce communication delay, increase the reliability of the device, and when one submodule or front panel or rear panel fails, the remaining submodule or front panel or rear panel can replace the function of the failed submodule or panel, support the train to complete the running task on time, and reduce the risk of communication failure of the train.

[0030] The signal processing module includes a signal filtering circuit and a signal amplification circuit connected in series.

[0031] As shown in Figure 3 The train-mounted communication device in another embodiment further includes an overvoltage protection module; the overvoltage protection module is connected to the power supply module.

[0032] The positioning module uses the Beidou satellite navigation system or the ground enhancement system for positioning. Since the train runs in tunnels or remote areas during the running process, the Beidou satellite navigation system or the ground enhancement system can accurately position the train, effectively increase the contact between the train and the train and the train and the ground control station, and prevent the problem of being unable to locate the position.

[0033] As shown in Figure 4 The train-mounted communication device in another embodiment further includes a monitoring module and a coding-decoding module.

[0034] The monitoring module can adopt a microcontroller or a processor to detect the running state of the signal processing module, the MCU module and the UART module, collect the running state of the modules in real time and improve the working efficiency of the modules by monitoring the running state, so that the train can not lose contact with the train or the ground control, thereby preventing the problem of loss of social resources.

[0035] The encoding-decoding module is used for decoding the signal received by the communication connection module or the UART module or encoding the signal emitted, and different encoding / decoding formats are used to express the signal in each encoding or decoding process, so that the anti-interference ability of the signal in the transmission process can be improved, and the problem of repeated transmission of the same data to cause the communication error of the train and the failure of the train to be arranged correctly in time can be prevented.

[0036] In summary, the MCU and the UART008 serial communication control board are combined to form a modular control module, so that the flexibility and maintainability of the system are improved, a plurality of communication standards such as RS232, RS422 and RS485 are supported, different communication distances and environmental requirements are adapted, two communication modes are provided, the UART008 serial communication control board or the communication connection module can be selected for data transmission according to the size of the data, the application range of the device is widened, the effective communication between the trains, the effective communication between the trains and the ground control console and the intelligent traffic purpose are achieved.
