At present, high-speed trains are generally equipped with onboard recorders. Once an incident occurs while the train is in motion, it is generally only necessary to find the onboard recorder on the train, export the data from the recorder, and analyze and query the cause of the incident, whether it is mechanical failure or personnel misoperation.

However, in some incidents, the damage to the train may also lead to the damage of the onboard recorder. Once the onboard recorder cannot be corrected, the internal data cannot be exported, resulting in the inability to determine the cause of the incident. In order to overcome the shortcomings of existing skills, this utility model provides a vehicle mounted recorder that can transmit real-time data of train travel back to the main station through a wireless network.

In order to achieve the above objectives, the present utility model proposes an onboard recorder for high-speed trains, comprising a main control chip, a power circuit separately connected to the main control chip, a power indicator light, and a recorder reset button, characterized in that it also separately includes an Ethernet chip connected to the main control chip.

Decoder, alarm, clock circuit, USB extender, 3G wireless transmission module, SD card slot, console interface, network card indicator light, watchdog circuit; Further comprising a SIM card slot connected to the 3G wireless transmission module. The main control chip is a CPU chip based on RISC architecture.
