Fig. 2 is a schematic diagram of a train entrance detection system according to an embodiment of the present invention, as shown in fig. 2, in the embodiment of the present invention, whether a train exits from a garage is detected by arranging an entrance detection axle counting outside a parking garage line, when a communication train exits from the garage, the axle counting is occupied, and at this time, an entrance signal may display the occupancy state of the axle counting by lighting up, for example, an entrance signal displays a red light, which indicates that an entrance detection axle counting section is occupied, and the train is not allowed to exit from the garage. At the moment, the train control center TMC controls the train to go out of the warehouse by acquiring the occupation of the entrance detection meter shaft and the lighting state of the signal machine in real time through the object controller OC. The object controller OC is information acquisition and control equipment of outdoor trackside equipment and is used for acquiring the occupation information of the entrance detection axle and the lighting state of the entrance annunciator and sending the acquired information to the train control center TMC.
In addition, the vehicle-to-vehicle communication system does not arrange an axle counting device on a section, and only arranges an entrance detection axle counting section and an entrance signal machine in a transition section from a vehicle section to the section. Generally, only two axle counting devices are required for the entrance detection axle counting section, so that the number of axles counting of the whole line is greatly reduced.
It should be noted that TMC is used as a train information management center, and the operation information (such as occupancy of a counting shaft, a state of a traffic signal, and position information of the train) of the whole train can be acquired at every moment, so that a driver can be prevented from running a red light.
