The working process of the electric control system of the vehicle-mounted radar antenna hydraulic frame withdrawing mechanism is as follows:
after receiving a control instruction from the panel or the lower control box, the upper control box detects whether a corresponding in-place signal meets the action preposition requirement, controls an electromagnetic valve group at the upper part of the vehicle when the in-place signal is normal, and stops acting and transmits fault information to the panel indicator light and the lower control box when the in-place signal is abnormal; after receiving a control instruction from a panel or a remote control handle, an upper control box detects whether a corresponding in-place signal meets the action preposition requirement, when the in-place signal is normal, a control message is sent to the upper control box, the upper control box controls electromagnetic valves at the upper parts of a hydraulic station and a carrier vehicle or directly controls an electromagnetic valve group at the lower part, and when the in-place signal is abnormal, the upper control box stops acting and transmits fault information to a panel indicator light and the remote control handle; the remote control handle is directly connected with the lower control box through a cable, and sends a remote control instruction to the lower control box in a remote control mode.

The upper control box and the lower control box realize the monitoring of the in-place state of each solenoid valve action corresponding to a specific travel switch through autonomous programming software, and in the 'local control' state, when the upper control box and the lower control box receive an output instruction of the solenoid valve group, a control signal can be output only when the in-place signal of the travel switch is normal; and when the abnormal in-place signal of the travel switch is detected, suspending the system action and reporting the fault. In the 'local control' state, each step of each combined action detects the in-place signal state, the next action is carried out only if the in-place signal is normal, and the in-place signals of part of important parts are detected in the whole process (for example, the antenna main tower is required to be in the lodging in-place state in the process of unfolding the antenna array surface, otherwise, potential safety hazards can occur). And when the fault of the position signal of the travel switch is detected, suspending the system action and reporting the fault. When the system is in the 'protection-removing' state, the actions of all the electromagnetic valve groups are not influenced by the travel switches, meanwhile, in the 'protection-removing' state, the combined action on the remote controller cannot be carried out, and the system can only be in the 'local control' state, so that the reliability of the system is ensured.
