海拔高度测量仪设计

Design of the altitude measurement instrument

采用嵌入式STM32F103RBT6微处理器,通过I2C接口总线读取数字气压传感器BMP085数据,并实现传感器BMP085的初始化参数配置。根据海拔高度与大气压力及温度的转换关系,换算成海拔高度,并通过RS485总线,将测量数据传送给上位机MCGS触摸屏,完成多点大气压力、环境温度、海拔高度的显示与实时曲线绘制。

Using embedded STM32F103RBT6 microprocessor,digital pressure sensor BMP〈085 data read through the I2 C interface bus,and realizes the initialization parameter sensor BMP〈085 configuration.According to the elevation and the atmospheric pressure and temperature of conversions,the data was converted to altitude. And through the RS485 bus,the measuring data transmitted to the PC MCGS touch screen,complete more atmospheric pressure,temperature,altitude and real- time curve drawing shows.
