In the midst of the development of transportation such as private cars and passenger cars, subways and trains are becoming important transportation means for resolving urban traffic problems or transporting distances between cities and regions. In addition, subways and trains are preferred by the general public because they have higher safety than other transportation systems by operating on tracks. In addition, since a train connected to a large number of vehicles delivers a large number of people and goods in one operation, safety and accuracy of the operation must be secured first.

This problem makes an unstable train operation that requires absolute safety.

In addition, it is important to monitor and control the entry and exit of the train as a whole. In other words, since a large number of trains are operated at a certain distance on the track, the speed and distance of these trains must be properly controlled to ensure efficient operation.

Therefore, a number of accidents have occurred in the operation control of trains that are considered to be safe, and more advanced and safe control of train operation is required. In addition, there is a demand for a variety of devices to further increase the safety, and research on the train operation system that can carry out safe operation in the academic field is actively being conducted.

Accordingly, an object of the present invention for solving the above-mentioned problems is to transmit driving information via wired and wireless between neighboring occlusion control boxes, and to configure a dual internal circuit to a preliminary operating system in case of malfunction of a commercial operating system. It is to provide the technology for the automatic occlusion electronic unit of the train due to the stability and accuracy of the operation by configuring the automatic switching operation and monitoring the overall train operation status.
