[0025] In the process of automatically traveling along the rail by the self-propelled trolley, the pulse signal sensor arranged on the wheel collects the pulse signal output when the wheel rotates (assuming that 5000 pulse signals are output when the wheel rotates one circle), and sends the collected pulse signal to the laser camera assembly. After the laser camera assembly receives the pulse signal as a trigger signal, the laser sensor in the laser camera assembly is controlled by the control mainboard to emit a laser line to the inner side wall of the rail on both sides when the 1000th pulse signal is collected by the pulse signal sensor, that is, when the wheel rotates one fifth of a circle. At the same time, the camera is controlled to capture the rail profile image formed by the laser line on the rail.

[0028] Preferably, the industrial computer is an EPE-6113LP4 industrial computer, and is connected with the laser camera assembly and the display through cables respectively.
