Method for positioning and transmitting information of hydrological monitoring equipment in non-signal area

The invention discloses a method for positioning and transmitting information of hydrological monitoring equipment in a signal-free area, which combines a wireless communication technology with hydrological monitoring equipment based on hydrodynamic force, and can solve the problem of hydrological monitoring information transmission in the signal-free area such as a hydraulic tunnel. Firstly, a magnetic mark composed of LoRa (long-distance radio) terminal equipment and a UWB (ultra wide band) technology is arranged above the interior of a tunnel without signals at an interval of 500m, when hydrologic monitoring equipment put into use passes through the range of the magnetic mark, the LoRa terminal equipment in the magnetic mark can automatically start an internal communication protocol, data monitored by the equipment are received, and the data are transmitted to the tunnel through the LoRa terminal equipment; and then data transmission is carried out by using a LoRa communication protocol between the magneti
