Trolley left-right linear synchronous travelling control circuit, control method and detection device

The invention discloses a trolley left-right linear synchronous travelling control circuit, control method and detection device, relating to a technology used for checking linear synchronous travelling control of a trolley outside various steel box girders, aiming at providing a trolley left-right linear synchronous travelling control circuit with high accuracy, simple structure and good reliability, a control method and a detection device. The invention has the key point that the control circuit comprises an encoder, a controller, a driving unit, a left travelling actuating mechanism and a right travelling actuating mechanism, wherein the encoder is used for detecting relative angles of the left travelling actuating mechanism and the right travelling actuating mechanism of the trolley; the controller is used for receiving angle information output by the encoder, carrying out logical judgment and operation according to the angle information and outputting a driving signal to a driving unit, and the driving unit is used for driving the left travelling actuating mechanism and the right travelling actuating mechanism to move according to the driving signal. The trolley left-right linear synchronous travelling control circuit, control method and detection device in the invention are mainly used for checking linear synchronous travelling control of the trolley outside various steel box girders.
