Abstract

The present invention relates to a motion control system intermediate position detecting protecting device which is provided with an intermediate position detecting switch, a protecting function auxiliary relay and an intermediate position protecting switch, wherein the intermediate position detecting switch and the protecting function auxiliary relay are connected with a controller. The normally closed contact of the intermediate position protecting switch and the normally open contact of the protecting function auxiliary relay are connected in parallel. The normally open contract of the protecting function auxiliary relay is connected in series in the control circuit of the starting relay of the electric motor. The normally open contract of the intermediate position detecting switch is arranged in the control circuit of the protecting function auxiliary relay. The invention uses a simple hardware circuit to establish the system. The resource wastage of the controller is avoided and the moving component breakage risk caused by the confusion of software control is reduced. The position of the fault is expressed openly and the maintenance is facilitated. The invention also has the advantages of reliable protecting function, low cost and broad application sphere.

Description

technical field

[0001] The invention relates to a detection and protection device in a motion control system of medical equipment, in particular to a detection and protection device for an intermediate position of the motion control system. Background technique

[0002] In the prior art, the moving parts of the medical equipment are driven by the motor, and each detection switch is disconnected or turned on by the block running synchronously with the moving part, and the controller sends instructions according to the input signal of each detection switch to control the operation or stop. Each of the detection switches includes a motion control system middle position detection switch and a protection switch for a failure fault, and adopts the following electrical structure, such as figure 1 As shown, the intermediate position protection switch S2 is installed adjacent to the intermediate position detection switch S1, its normally closed contact is connected in parallel with ...
