Embodiment Construction
[0020] Such as figure 1 As shown, the present invention includes unmanned aerial vehicle, camera, detector, tourist carrying beacon and ground measurement and control station, and unmanned aerial vehicle is the oil-driven type fixed-wing unmanned aerial vehicle equipped with autopilot, with a wingspan of 3 meters , payload 3kg, maximum flight altitude 5500 meters, built-in digital radio. The camera adopts a digital camera with a cable release, and in the present embodiment adopts a Canon mark 5D II single-lens reflex digital camera with effective pixels of 21.1 million, and the ground measurement and control station controls the camera to take pictures.
[0021] The detector is mounted on the unmanned aircraft, searches along the planned route, and transmits wireless signals at regular intervals to activate the beacons carried by tourists on the ground, and at the same time continuously receives the response signals of the beacons (including ID, GPS, and current time informat...

The invention discloses a system for searching tourists in danger in scenic spots, which comprises an unmanned machine, a camera, a detector, a tourist-carried beacon and a ground measuring and controlling station, wherein the detector is mainly composed of a main control chip, a wireless receiving and transmitting module, a SD (Secure Digital) memory card, a voltage conversion module, a lithium battery and an antenna; and the tourist-carried beacon is mainly composed of a main control chip, a voltage conversion module, a wireless receiving and transmitting module, a voice control chip, a GPS (Global Positioning System) module, a horn, an antenna and a lithium battery. In the invention, the unmanned machine is used as a search and rescue platform for searching and positioning tourists in danger through the wireless communication connection between the airborne detector and the tourist-carried beacon by utilizing the GPS technology. Compared with the prior art, the system disclosed by the invention has the advantages that the structure is simple, the manufacturing cost is low, and search signals are basically not limited, so that the search efficiency and the rescue success rate can be obviously improved and the cost and risk in search operation can also be greatly reduced, thereby being favorable for maintaining the excellent image of scenic spots.
Description
technical field [0001] The invention relates to a search system, in particular to a search system for searching based on wireless signals emitted by tourists carrying beacons. The system is especially suitable for scenic spots with complex terrain conditions and large areas such as mountains and deserts. Background technique [0002] With the vigorous development of domestic and foreign tourism, people's demand for tourism is no longer satisfied with general sightseeing tourism, and outdoor adventure tourism is increasing day by day. At the same time, some relatively primitive mountains, deserts, canyons and other areas are gradually being developed into scenic spots due to their mysterious natural scenery and beautiful ecological environment, attracting tourists to visit and explore. Such scenic spots generally have many characteristics such as vast area, high altitude, complex terrain, poor climate conditions, prone to geological disasters, lush vegetation coverage and uns...
