摘　　要：介绍一种以51系列单片机STC89C52作为核心控制器的便携式高度测量仪的设计方法。其采用气压传感器BMP180采集相应的气压等数据,采取I2C通信协议与单片机进行串口通信,用C语言编写了相关的计算和补偿的软件程序,将气压值转换成海拔高度。实践表明,该设计能够快速并且较准确地测量出测量仪所处位置的气压值和海拔高度。A design method of the portable height measurement instrument with the 51-series microcontroller STC89C52 as the core controller is introduced.The barometric sensor BMP180 is used to collect the corresponding barometric pressure data.The serial port communication between the barometric sensor and SCM is conducted by using the I2C communication protocol.The related software program for calculation and compensation is compiled with C language,so as to convert the barometric pres-sure value to the altitude value.The practice shows that the design method can quickly and accurately measure the barometric value and altitude of the position that the measuring instrument is located at.
