重庆大学 重庆大学硕士学位论文 英文摘要 PAGE PAGE IV ③ This paper realized the control to each module of the measurement and control system.The functions of bubble disturbing, cleaning, discharging, constant temperature control were realized for the sample reaction and detection module, and the strength of bubble disturbing can be switched. The sequent inject and the self-detection circuit were designed, and this paper realized the leakage self-checking, power-off protection, chassis temperature control. ④ The embedded platform which based on Raspberry Pi was completed, including the development environment, wiringPi library development, touch screen, remote control. The hardware resources of measurement and control system can be controlled through GPIO, USB and I2C interface on Raspberry Pi board. ⑤ This paper completed the debugging of the motherboard of the measurement and control system, built the system testing platform, completed the commissioning of each module, completed the experiment of cleaning and water quality parameters testing.
