摘　　要：针对传统的pH参数测量仪存在的有线数据传输、操作复杂、不便携带、价格昂贵等问题,提出了基于Android系统的pH参数测量仪研制。该测量仪与Android系统的结合实现了测量的无线传输和在线监控功能。以单片机为控制核心的测量模块完成信号采集和温度采集,并经信号滤波、参数标定、温度补偿等数据处理后由蓝牙与Android系统建立通信。实际测试表明,该仪器能实现对pH精确测量,并通过蓝牙与Android手机准确的收发数据,使用方便、快捷,操作简单,具有很好的应用前景。Regarding the existing problems of traditional measuring instrument of pH parameters like the complexity of cable data transmission and operation,inconvenience of carrying and expensive price,this paper proposed the measuring instrument of pH parameters based on the Android system. This measuring instrument combined with the Android system to achieve the wireless transmission of measurement and online monitoring. Microprocessor completes gathering the pH and temperature signal. Then it established communication with the Android system via the Bluetooth after signal filtering,parameter calibrating,temperature compensating. Tests show that the instrument can accurately measure pH parameter and can send and receive data through Bluetooth and Android mobile phone,which is convenient,quick and also with simple operation and a very good application prospect.
