System and method for ground information acquisition

Abstract

The invention discloses a system and a method information acquisition. The system comprises a wireless sensing network, an information acquisition device and a third wireless communication link, wherein the wireless sensing network is arranged at a ground area; the information acquisition device is fixed on an unmanned plane and wirelessly connected with a ground control center for receiving flight command and task instruction; and the third wireless communication link is connected with the information acquisition device and the wireless sensing network, sends the command information of the information acquisition device to the wireless sensing network, sends data information acquired by the wireless sensing network to the information acquisition device, and is used for monitoring the wireless sensing network of the ground area; and when the unmanned plane enters the space above the ground area covered by the wireless sensing network, a communication unit of the wireless sensing network sends a data transmission command to the wireless sensing network of the ground area by adopting a broadcasting mode, and the wireless sensing network generates ground surface data according to theground data information received by a ground sensor and transmits the ground surface data to the communication unit of the wireless sensing network. The invention forms an aerial non-touch system forquickly monitoring and acquiring ground surface information, which is suitable for acquiring the ground information of large area.

Description

Technical field: [0001] The invention belongs to the field of intelligent control and sensor networks, and relates to a system and method for collecting and monitoring ground data information by using an unmanned aerial vehicle and a wireless sensor network. Background technique: [0002] For the collection of temperature, humidity and pH of ground information, the current main method is on-site measurement. Artificially carry sensors and GPS to the designated area, gradually record the data information and location information of each point, and then draw the ground information distribution map through the computer. Obviously, the field measurement method for ground information collection has very low efficiency, and it is not suitable to use this method when collecting ground information in a large area. [0003] For the collection of ground temperature information, thermal infrared remote sensing image method can be used. This method has the advantages of high efficiency...
