Environment monitoring system and vibration sensing device

An environment monitoring system is utilized for monitoring an environmental variation status of a riverbed, a lake floor, or a seabed. The environment monitor system includes a wire drawing device configured at a monitoring point for releasing and tightening a transmission wire; a fixing pipe laid between the monitoring point and a structure layer for containing the transmission wire; a plurality of vibration sensing devices respectively configured on the transmission wire for converting sensed vibration energy to a plurality of electronic signals and transmitting the plurality of electronic signals by the transmission wire; an analyzing device coupled with the wire drawing device and the transmission wire for obtaining a releasing length of the transmission wire by the wire drawing device and determining the environmental variation status according to the releasing length and the plurality of electronic signals to perform monitoring.
