and controlling the side panel and the handheld device to flash the indicator lamp so as to remind a user of faults.
9. The method for detecting the position of the brake state of an operating table according to claim 7, wherein the abnormal in-place detection switch is a second micro switch, and when the brake hydraulic cylinder moves beyond the first micro switch to the set distance, the spring sheet of the second micro switch is pressed, so that the second micro switch generates the abnormal in-place signal.
10. A brake status position detection system for an operating table, comprising:
the hydraulic cylinder assembly comprises a bed body control hydraulic cylinder assembly and a brake hydraulic cylinder, the brake hydraulic cylinder is used for driving the brake action of the operating table, and the bed body control hydraulic cylinder assembly is used for driving other actions of the operating table except the brake action;
the in-place detection switch is arranged in the advancing direction of the brake hydraulic cylinder and is used for generating an in-place signal under in-place triggering of the brake hydraulic cylinder;
the abnormal in-place detection switch is arranged in the travelling direction of the brake hydraulic cylinder and is positioned at a set distance in front of the brake in-place detection switch and is used for generating an abnormal in-place signal under the triggering of the abnormal in-place detection switch;
the main control board is respectively connected and communicated with the hydraulic cylinder assembly, the in-place detection switch and the abnormal in-place detection switch and is used for running a program to realize the brake state position detection method of the operating bed according to any one of claims 1-9.
