Usually, it is equipment such as routers, firewalls or routing security integrated machines; DTU (Data Transfer unit) is a wireless terminal device specifically used to convert serial port data into IP data or convert IP data into serial port data and transmit it through a wireless communication network.

[0003] Existing integrated network devices are large in size and expensive, and the troubleshooting of integrated network devices is relatively cumbersome. If there are problems with remote control, it is necessary to analyze the problems of control signals or network signals.

[0004] Therefore, the utility model provides a remote driving control signal transmission system for a new type of loader to solve the above problems. Content of the Utility Model

[0007] Information is transmitted in the system through CAN signals and network signals;

[0008] The network signal is transmitted bidirectionally between the two 5G gateways, and each of the two 5G networks is connected to a CAN to Ethernet module;
