Big data system for environmental monitoring

The invention relates to a big data system for environmental monitoring based on a pump station fault detection system. The big data system includes a big data monitoring center and a plurality of monitoring stations. The big data monitoring center includes a router for being connected with the Internet, a data server mainframe, a data server standby machine and a plurality of working stations. Each monitoring station is connected with the Internet through an exchanger. The monitoring stations are in wireless communication with an unmanned aerial vehicle through a 4G wireless communication network, to obtain environmental data monitored by the unmanned aerial vehicle. The unmanned aerial vehicle includes a central control unit, a GPS module, a 4G communication module, a camera, a PM2.5 sensor or a poisonous gas sensor, wherein the GPS module and the 4G communication module are connected with the central control unit; and the camera, the PM2.5 sensor or the poisonous gas sensor is usedfor obtaining environment
