Trackside sensing system and method

The invention provides a trackside sensing system and a trackside sensing method. The system comprises a plurality of trackside sensing devices; the trackside sensing devices are arranged on the outer side of the traveling track, and any two adjacent trackside sensing devices located on the same side are spaced by a first preset distance; any two trackside sensing devices are in Mesh connection; the trackside sensing device is used for collecting sensing data in the area where the trackside sensing device is located, obtaining a sensing result of the area based on the sensing data and then sending the sensing result of the area to the monitoring center server so that the monitoring center server can make a response based on the sensing result of the area. According to the trackside sensing system and method provided by the invention, the related equipment cost and construction cost investment of the trackside sensing system can be reduced, the workload of related later maintenance work of the trackside sensin
