The test system mainly consists of five parts: the carrier vehicle 1 and its supporting equipment, the carrier vehicle 2 and its supporting equipment, the line for carrier vehicle 1, the line for carrier vehicle 2, and the control room. The control room contains computers, wireless communication devices, and wired network interfaces, etc. The control room realizes wireless control over the carrier vehicle 1 and the carrier vehicle 2, or receives control from a higher-level computer through the wired network interface to achieve remote control of the test system. The carrier vehicle 1 and the carrier vehicle 2 use the control room to communicate with each other and move in coordination. (1) The overall system participates in planning, overall system design, vehicle design and manufacturing, commissioning, etc.; (2) Specific technologies include very small radius, remote wireless control, high requirements for position and speed accuracy, etc.
