| Abstract |
The electronic interlocking system controls train routes to ensure the safe operation of trains. This system analyzes and regulates the interdependent sequential locking conditions of the elements constituting a train route to prevent overlaps, conflicts, or unsafe conditions with other train routes. Additionally, it is used to control field signaling equipment during frequent shunting or maintenance operations within station yards. This paper examines the architecture and operational method of the electronic interlocking system and proposes a method to remotely manage control inputs while maintaining system reliability. The proposed method enables operators to transmit control inputs to the electronic interlocking system from a remote location and to monitor the status of on-site signaling equipment in real time. This method utilizes wireless communication to transmit control commands, incorporating security measures to ensure data integrity and confidentiality. To verify the proposed method, a remote control device for the electronic interlocking system was developed, and simulations and field tests were conducted. The test results demonstrate that the railway signaling equipment (e.g., switch) can be remotely controlled in a secure and efficient manner. |
