Abstract

The invention discloses a shunting monitoring system for a railway, which belongs to the technical field of railway safety monitoring and comprises vehicle-mounted equipment and ground equipment, wherein the vehicle-mounted equipment comprises a shunting monitoring host and locomotive sensors, the ground equipment comprises the ground sensors, the locomotive sensors are in communication connection with the ground sensors, and the shunting monitoring host comprises a monitoring host and a machine case, and a plurality of functional reserved bits are arranged on the machine case. Compared with the prior art, the shunting monitoring system for the railway constructs full-link redundancy from data processing and communication to power supply through the hot standby redundancy of the information processing unit, the double-set parallel operation of the machine-induced communication unit and the double-path power supply and the standby battery, and greatly improves the fault tolerance capability and uninterrupted operation time of the system. The key train-ground communication data is encrypted by adopting the industrial AES encryption algorithm, so that the data is effectively prevented from being maliciously stolen or tampered in the transmission process, and the safety of a shunting instruction is ensured.
