Problems solved by technology

Setting hardware devices to simulate the sending and receiving signals of RIOM can only simulate a single action, but cannot realize closed-loop control, cannot complete combined tests related to timing and interval time, and cannot complete the hardware test items of the network control system. Full coverage; Secondly, the RIOM docking equipment is relatively fixed, and the applicability and flexibility of the platform are low after replacing the number of RIOM boards / channels
