基于STM32的无人机雪橇式减震器监测系统设计

Design of Embedded Sled Type Shock Absorber Monitoring System Based on STM32

摘要:

为了能够对飞机雪橇式减震器的压力进行实时监测和数据保存,设计了一种基于STM32F103ZET6的雪橇式减震器检测系统;利用压力传感器和光栅尺完成减震器压力与压缩距离的采集并转换为数字信号,以C#软件平台开发的作为上位机采集,处理压力数据,借助图形用户接口控件实现压力数据和曲线的显示,借助SQL数据库实现将数据保存在数据库中,便于管理员读取;上位机与下位机的传输利用WIFI信号进行;测试结果表明:雪橇式减震器监测系统精度达到0.01%。

Abstract:

In order to real-time monitor pressure of UAV’s shock absorber and save data, a new embedded shock absorber pressure monitoring system based on STM32F103ZET6 is introduced. The pressure sensor and linear encoder is applicated for complete shock absorber pressure and range acquisition and converted into digital signal. The C# software platform as a upper monitor, the data and curves are shown with the graphical user interface widget, with SQL to save pressure data, which help administrator refer to. Data is transmitted to PC through WIFI module. The test results are shown that the accuracy of shock absorber pressure monitoring system reached 0.01%.
