Research on All Electronic Interlocking Remote Monitoring System Based on Narrow Band Internet of Things

With the development of all electronic interlocking system and in view of the characteristics of all electronic interlocking system execution units, a remote monitoring system of all electronic interlocking system is designed based on narrow-band internet of things technology from two aspects of system hardware and software, so as to meet the requirements of real-time system monitoring and effective equipment maintenance. On this basis, through the analysis of potential security risks(e. g. theft and forgery that) in the data transmission process of the system during interactive communication, the encryption model of system communication data is proposed and key update algorithm is optimized. The results of system test, communication data encryption model and key update algorithm verification show that all electronic interlocking remote monitoring system can monitor all electronic interlocking system equipment in real time and securely transmit the device status or fault information displayed on the user terminal. The proposed communication data encryption model and key update algorithm effectively guarantee the transmission of communication data, and the system design meets the needs of railway safe operation and maintenance.
