Design of Infrared Oil Measuring Instrument Based on STM32

摘要

The water pollution caused by oil substances become more and more serious. In order to facilitate the monitoring of oil substances in water, an infrared measuring instrument based on the principles of infrared spectrophotometry, was developed from STM32F103RC processor. Main components of the hardware are light source system; signal acquisition and processing system; STM32-configuration industrial serial port screen (touch screen) control system. Touch screen is designed for the host computer interface. Through the operation of the touch screen interface, the functions of various modules of the instrument can be achieved. The absorbance, concentration, and draw the standard curve can be automatically calculated. The test is simple, high precision and intelligent.
