Problems solved by technology
Most of the high-speed railways are bridges and tunnels. Especially in the northwest region, there are long and dense tunnel groups. Signal equipment, relay stations, and even stations are set up in the tunnels. Complete the maintenance of signal equipment within the specified time, which will cause unsafe train operation. Therefore, it is imminent to establish a set of signal maintenance intelligent control and maintenance technology suitable for high-speed railway long and dense tunnel group conditions

The invention relates to a railway signal comprehensive maintenance system and method based on an intelligent decision-making expert system. To establish an intelligent control and maintenance technology for signal repair and maintenance under a long and large dense tunnel group condition of a high-speed railway is extremely urgent. The railway signal comprehensive maintenance system takes a high-speed railway signal system as the basis; an indoor microcomputer monitoring system is used for realizing acquisition of indoor equipment state information, and an intelligent AGENT unit is used for acquiring voltage and current of outdoor signal equipment in real time; and finally, acquired equipment information is recorded into each grade of database server, and fault information of an expert knowledge base is used for carrying out comparing judgment or pre-judgment or for providing a fault solution fed back to each grade of intelligent display terminal to guide signal maintainers to carry out fault processing. According to the railway signal comprehensive maintenance system, the risks that the system loses efficacy under the influence of manual factors or equipment, environment and other factors in a full life circle process of the signal system are reduced; and the working performance of the signal system is effectively improved, the faults are reduced and the operation risks are reduced.
Description
technical field [0001] The invention belongs to the technical field of railway signal operation maintenance and operation safety, and in particular relates to a comprehensive railway signal maintenance system based on an intelligent decision-making expert system and a method thereof. Background technique [0002] As an important system of high-speed railway train operation control, the signal system is the core to ensure the safety of train operation. Therefore, higher requirements are put forward for the maintenance and repair of signal equipment under high-speed railway conditions. Most of the high-speed railways are bridges and tunnels. Especially in the northwest region, there are long and dense tunnel groups. Signal equipment, relay stations, and even stations are set up in the tunnels. Completing the maintenance of signal equipment within the specified time will cause unsafe train operation. Therefore, it is imminent to establish a set of signal maintenance intelligen...
