Online monitoring and scheduling system for urban rail transit

The invention relates to an online monitoring and scheduling system for urban rail transit. The online monitoring and scheduling system comprises a sensor network, a monitoring and scheduling center and an expert platform, the sensor network comprises multiple multifunctional signal collectors, each multifunctional signal collector comprises multiple sensors, and the monitoring and scheduling center comprises storage equipment, display equipment, monitoring software and scheduling equipment. Therefore, through the online monitoring and scheduling system, adding or reducing of sensors on a moving rail train at any time can be realized without causing influence on the whole system; various sensors exist on a same wireless sensing node, so that topological structure is simplified, and system cost is lowered; wireless sensors mounted in tunnels and on rails and bridges and sensors mounted on trains traveling at a high speed are enabled to form a huge wireless sensor network.
