Provided is a synchronous detection device for a step chain wheel of an escalator. A first step chain wheel and a second step chain wheel are installed at the two ends of a main shaft respectively, and the synchronous detection device comprises a first rotating speed sensor, a second rotating speed sensor and a controller; the first rotating speed sensor is arranged to detect the rotating speed of the first step chain wheel and generate a corresponding first rotating speed signal; the second rotating speed sensor is arranged to detect the rotating speed of the second step chain wheel and generate a corresponding second rotating speed signal; and the controller calculates a phase difference between the first step chain wheel and the second step chain wheel based on the received first rotating speed signal and second rotating speed signal. The escalator comprises the synchronous detection device.
