多参数水质检测仪的控制系统大多价格昂贵、自动化程度较低、开发周期长。针对这种情况，提出了一种基于树莓派的多参数水质检测仪控制系统，阐述了该系统的架构，设计了光源、微型电机、多位阀、注射泵及RTC控制模块，利用wiringPi集成库实现了树莓派板载GPIO、PWM、UART等硬件的驱动，并在树莓派Raspbian系统下通过QT编写了控制软件，用于控制仪器各个模块。实验测试结果表明：该控制系统实现对了仪器的自动化控制，且操作友好、运行稳定、易升级，满足多参数水质检测仪实际应用需求。

Most of the control systems for multi-parameter water quality monitor have the problems of high cost,low automation and long development period. In view of this, new control system for multi-parameter water quality monitor which was based on Raspberry pi was proposed.The structure of the system was analyzed,and the control modules of light source,micro-motor,multi-po-sition valve,syringe pump and RTC were designed.The wiringPi which is a GPIO access library was used to drive the Raspberry Pi’s hardware including GPIO,PWM and UART.Under the Raspbian system,the control software was programmed to control every module of the instrument.Test results show that the system implements the automatic control of the instrument,and it has the prop-erties of friendly interface,stable operation,and easy updation.It reaches the requirements of practical application.
