Interference detection and positioning method for rail transit wireless network

The invention discloses an interference detection and positioning method for a rail transit wireless network, which is mainly used for wireless network operation and maintenance in a rail transit application scene and aims to solve the problems that wireless signal interference is difficult to detect and an interference source is difficult to position in a long-distance rail line. The method comprises the following steps: (1) in a data collection and preprocessing stage, scanning a wireless signal by using radio hardware equipment; (2) performing signal characteristic analysis and interferencesignal detection; and (3) performing real-time position calculation in combination with wireless signals, an accelerometer sensor and GPS signals. The method is applied to a rail transit system, operation and maintenance of a rail transit wireless network can be assisted with a low-cost system, real-time position information of a train is provided while signal interference detection is effectively carried out, and the oc
