The invention discloses a rail transit accident monitoring system and method based on wireless communication, and relates to the technical field of rail transit accident monitoring. The system comprises a data acquisition and processing module, a state evaluation module, a data analysis module, a real-time monitoring module and an accident judgment and response module. The data acquisition and processing module collects historical data of nodes in a monitoring area, obtains log data and marks the historical data; the state evaluation module evaluates the operation state of the wireless sensor node and identifies a key node; the data analysis module analyzes a trend curve according to historical data of the key nodes, extracts trend characteristics and establishes a mapping relation between the trend characteristics and the trend curve; the real-time monitoring module obtains accident notifications and real-time data of the key nodes in real time, generates a trend curve and extracts real-time trend characteristics; and the accident judgment and response module calculates a deviation degree index, judges the accuracy of accident notification and outputs related notification information.
