Abstract
A positioning and information transmission method of a hydrological monitoring device in a single-free area combines a wireless communication technology with a hydrodynamics-based hydrological monitoring device, which can solve the problem of hydrological monitoring information transmission in a signal-free area such as a hydraulic tunnel. First, magnetic beacons each composed of an LoRa (long distance radio) terminal device and an ultra-wideband technology are arranged at the top of the interior of a signal-free tunnel at an interval of 500 m. When a hydrological monitoring device in use enters a coverage area of the magnetic beacon, the LoRa terminal device in the magnetic beacon will automatically start an internal communication protocol and receive data acquired by the device by monitoring, the data is transmitted based on a mutual LoRa communication protocol between the magnetic beacons, and finally, the data is transmitted to a ground central control system for storage.
