Abstract
A security check instrument motion control system includes an FPGA control chip that receives motion instructions, comprising angle, direction, speed and the like, from an upper computer via an upper computer communication module, realizes quick control to a rotation motion module, and controls a motion state of the rotation motion module according to real-time motion information of the rotation motion module detected by a positioning detection module. The motion state includes a motion stop state and a normal rotation state. The FPGA control chip detects the working state of each module in the security check instrument motion control system in real time, and once the security check instrument motion control system has a fault, each module can be subjected to debugging, repairing and maintenance respectively. If the positioning detection module detects that the rotation motion module is abnormal, the FPGA control chip controls the rotation motion module to stop moving.
