The invention belongs to the technical field of rotor engine control, and particularly relates to a single-signal phase deceleration recognition system for a rotor engine driven by an eccentric shaft, the single-signal phase deceleration recognition system comprises an ECU, a signal processing module and a protective cover, the protective cover is rotatably mounted at the end of a main shaft, and a deceleration mechanism, a phase detection code disc and a phase sensor are arranged in the protective cover; the input end of the reducing mechanism is coaxially and fixedly connected with the main shaft, the output end of the reducing mechanism is coaxially and fixedly connected with the phase detection coded disc, and the reduction ratio of the reducing mechanism is integral multiples of the rotation speed ratio of the main shaft to the rotor; and the phase sensor is used for detecting a phase signal of a detection bit on the phase detection code disc and sending the phase signal to the ECU through the signal pro
