基于气体传感器的航空液压发电机滑油泄漏检测
Oil Leakage Detection of Aviation Hydraulic Generator Based on Gas Sensor

针对航空液压发电机地面测试实验中液压油泄漏的问题，设计了单片机和气体传感器为核心的液压油气体检测装置，可以检测探测区域内的液压油气体参数，单片机内部编写标准的Modbus-RTU协议，支持与上位机软件组态王内置的Modbus驱动进行通信。系统使用组态王设计人机交互界面，实时显示发电机周围各点位的气体参数、实时趋势曲线和历史趋势曲线，实现液压油泄露的远程检测。
Aiming at the problem of hydraulic oil leakage in aviation hydraulic generator ground test experi-ment, a hydraulic oil gas detection device with single chip microcomputer and gas sensor as the core is designed, which can detect the hydraulic oil gas parameters in the detection area. The standard Modbus-RTU protocol is written in the single chip microcomputer, which supports communication with the Modbus driver built in the upper computer software Kingview. The system us-es Kingview to design man-machine interface, real-time display gas parameters, real-time trend curve and historical trend curve around the generator, and realize remote detection of hydraulic oil leakage.
