The invention relates to the technical field of safety detection, and discloses a rope loosening and disordering safety control circuit and system, which are used for detecting whether a loose rope or a disordered rope occurs or not and performing safety control on an external winch body. The circuit comprises a power supply signal input end which is connected with a control signal input end and a voltage signal input end of a first controller separately, the control signal output end of the first controller is connected with the voltage signal input end of a detection component, the voltage signal output end of the detection component is connected with the control signal input end of a second controller, the voltage signal output end of the first controller is connected with the voltage signal input end of the second controller, and the voltage signal output end of the second controller is connected with the detection signal output end. According to the rope loosening and disordering safety control circuit, when abnormal conditions such as rope loosening or rope disordering, line disconnection, grounding or power loss of a voltage signal input end occur, the abnormal conditions can be detected in time, equipment in operation can be stopped immediately, and safety accidents are prevented.
Description
technical field [0001] The invention relates to the technical field of safety detection, in particular to a loose and messy rope safety control circuit and system. Background technique [0002] In order to perfectly present the effect of artistic expression, stage machinery has become an indispensable artistic means used by more and more stage designers in modern art performances and artistic creations. The switching of various scenes in the performance and the special form of sports art performance All need to be realized by stage machinery, and most stage machinery, especially stage machinery, are basically driven by hoists and wire ropes. [0003] The wire rope drive has the following two dangers. If it is not stopped in time, the consequences will be very serious, and it will directly endanger personal and equipment accidents: When the scene is falling, it is held by a pole or object next to it and cannot continue to fall. If it continues to fall at this time, the wire r...
