Meanwhile, the first microprocessor module controls the first image acquisition module to acquire images of the train head, and the train type of the train is identified by matching the acquired images with the train type images stored in the indicator light module database. After the type of the train is identified, the first micro-processing module controls the multi-degree-of-freedom adjusting module to act according to the type of the train, so that the first red light indicating module and the first green light indicating module are arranged opposite to a cab of the train, a driver can conveniently and smoothly observe the first red light indicating module and the first green light indicating module, and safety accidents caused by the fact that the driver cannot observe the first red light indicating module and the first green light indicating module can be effectively avoided.
