Design of Gateway in Airport Intelligent Bird-repelling System

Bird collision is one of the important factors threatening aviation safety, which seriously affects the safety of human life and property. Therefore, effective measures must be taken to prevent such incidents. According to the problems existing in the existing ways and methods of bird-repelling, this paper proposes a scheme of building an airport bird-repelling linkage system by using the Internet of Things technology. Because Zigbee network has its own shortcomings and is limited by the characteristics of airport geographic environment, it is necessary to solve the problem of long-distance communication between bird control center and bird repellent equipment. In this paper, STM32 is used as the core processor and combined with CC2530, CC2591 and GPRS modules to construct the gateway of bird-repelling intelligent system. The communication distance between Zigbee terminal and bird-repelling device is about 400 m, while the transmission power reaches the maximum + 22dBm and the acceptance sensitivity is −99.2dBm. In SIM900 terminal, due to its mobile operation, the gateway of bird-repelling intelligent system is constructed. Businessmen networked to achieve full coverage within the airport, and solved the data exchange between bird control center and bird-repelling equipment.
