Claim 0:
1. A control device of a lifting platform of a detection device, for controlling the lifting platform of the detection device, wherein the control device comprises:
a first distance measuring sensor, arranged at top of the detection device;
a first processor connected with the first distance measuring sensor, wherein the first processor is configured to obtain a first distance measurement instruction, and control the first distance measuring sensor to measure a first distance between the top of the detection device and an obstacle directly above the detection device according to the first distance measurement instruction;
wherein the first processor is further configured to obtain the first distance sent by the first distance measuring sensor, generate an elevation instruction according to the first distance, and control a lifting motor of the detection device to drive the lifting platform to rise to a target position from a current position according to the elevation instruction, such that the lifting platform does not collide with the obstacle,
wherein the control device further comprises:
a lifting motor drive circuit, wherein one end of the lifting motor drive circuit is connected to the lifting motor;
a safety redundant control circuit, connected with a power supply module for supplying power for the lifting motor drive circuit,
wherein the safety redundant control circuit is configured to generate a power-off instruction when it is determined that a second distance between a top of the lifting platform and the obstacle is smaller than a target distance during a process of the lifting platform rising to the target position, and control the power supply module to stop supplying power for the lifting motor drive circuit according to the power-off instruction.
