针对在现场测试中，机场桥载设备运行安全监控系统存在节点电池消耗过快及数据错误或丢失等问题，根据信道RSSI和电池间的关系特性，并结合系统工作环境，对节点硬件进行优化设计。同时，基于网络超帧和GTS管理机制，提出了按数据分类管理的节点RF增益和休眠优化方法。对优化后的节点进行信号测试和OPNET仿真。结果表明，该方法能有效降低节点能耗，且对其他系统性能没有产生负面影响。

Focusing on the problems of excessive node battery consumption which causes data loss or errors in the field tests of safety monitoring system for airport bridge and ground-borne equipment, the node hardware is designed optimally based on operation environment of the system and in accordance with the characteristic relationship between channel RSSI and battery. In addition, based on network superframe and GTS management mechanism;the optimal method for controlling RF gain and sleep policy of the node is proposed according to the data classification management. The optimized node is tested and OPNET simulation is conducted, the results show that this method effectively reduces energy consumption of the node, and the other performance of the system is not adversely affected.
