Embodiment 1
[0056] This embodiment discloses a dynamic wireless monitoring and positioning method for rockfall disasters on slopes, including the following steps:
[0057] Step 1. Arrange more than one rockfall monitoring terminal in the slope monitoring area;
[0058] Each rockfall monitoring terminal is installed on each potential rockfall surface of the slope monitoring area by manual arrangement or drone sowing (if multiple potential rockfalls need to be monitored, a rockfall monitoring terminal is installed on each potential rockfall surface, Such as figure 1 As shown; each rockfall monitoring terminal has a fixed and unique number; when the potential rockfall moves, the rockfall monitoring terminal installed on its surface will move accordingly;
[0059] Step 2. The rockfall monitoring terminal cooperates with the UAV cruise positioning system to obtain rockfall monitoring data;
[0060] In the UAV cruise positioning system, cruise in the slope monitoring area; during each round o...
Embodiment 2
[0064] This embodiment is on the basis of embodiment 1, as figure 1 As shown, the cruise route is planned in advance in the slope monitoring area; on the planned cruise route, a signal emission point is determined at a certain distance; during each round of cruise, the UAV cruises according to the pre-planned cruise route , and transmit a wireless electromagnetic wave signal at each signal transmitting point.
Embodiment 3
[0066] In this embodiment, on the basis of Embodiment 2, the UAV cruise positioning system performs positioning through the GPS high-precision positioning module, and transmits a wireless electromagnetic wave signal of a specific frequency band to the rockfall monitoring terminal through the signal transmission module at the planned signal transmission point, and According to the GPS high-precision timing positioning module, the time for each emission of radio electromagnetic wave signals is determined.
