The invention belongs to the technical field of vehicle detection, and provides a semitrailer rotation angle measuring device and method and electronic equipment.The device comprises a stay wire sensor, a processor, a circular sliding rail and a connecting piece, the circular sliding rail is coaxially and fixedly connected with a tractor of a semitrailer and a rotating shaft of the semitrailer, and the connecting piece is connected with the processor. One end of the connecting piece is in sliding connection with the circular sliding rail, the other end of the connecting piece is fixedly connected with the tractor, one end of the pull wire sensor is fixedly installed on the side, close to a trailer, of the circular sliding rail, and the other end of the pull wire sensor is fixedly installed on the connecting piece. A stay wire of the stay wire sensor is always tightly attached to the outer circle of a sliding groove of the circular sliding rail, the stay wire sensor is electrically connected with the processor and used for sending the length change value of the stay wire to the processor, and the processor is used for calculating the deflection angle of the connecting piece. The problems that in the prior art, a scheme for measuring the turning angle of the tractor and the trailer is complex in design and low in precision are effectively solved.
