针对双轴或单轴高精度角度测量的工况需要,采用8位单片机为主控芯片,高精度数字MEMS为传感器芯片设计了一种体积小、功耗低的无线数显角度测量仪.远端上位机通过ZigBee无线模块对测量仪进行操作和三维显示,同时集成OLED屏可就地显示测量数据.具有双轴±90°倾角测量和单轴绝对式0°~360°转角测量功能.测试结果表明:该测量仪测量精度为0.1°,具有较高的推广应用价值.%To meet the requirement of high precision double-axis or single-axis angle measurement,present a novel wireless digital display instrument for angle measuring,high precision digital MEMS measuring instrument with small volume and low power consumption for sensor chip by using 8-bit Microcontroller as the main control chip. The measuring instrument and three-dimensional display are being operated through ZigBee wireless module and the remote host computer. Meanwhile,integrated OLED screen can display measurement data on the spot with the function of double-axis ± 90° incline angle measurement and single-axis absolute 0°~360° turn angle measurement. The test results indicate that precision of this measuring instrument is 0. 1°,which has a high application value.
