As water resource is being more and more precious, and water pollution is becoming serious increasingly, it has been become one important issue which is concerned by society to protect water resource from pollution. The indispensable method to protect water resource is to detect quality of water, and detecting oli concentration of water is the significant aspect of water quality detection, so it is very meaningful in the side of society and economy to implement the Detector of Oil Concentration.In this article, the detailed introduction is shown about design and implementation of oil concentration detector based on microcontroller. There is many a method to measure oil concentration, but the commonly used one is Infrared Absorbance Luminosity Method, so firstly the article illustrates fundamental of Absorbance Luminosity Method for quantitative analysis - Lambert Beer Law, and puts up with the basic model for system measurement, and then designs measure logic of system. In the view of characteristics of basic model, the article gives RBFNN model for system measurement as supplement to the former, the result of test for RBFNN approves that the model is effective. The two models for system measurement coexist in target system; this is maintained by the high-level software perfectly. And then the article gives concrete implementation of system from two aspects of hardware and software. For hardware design, the schematic of system hardware is finished with the strategy of Modeling Schematic Design, and setup HAL (Hardware Abstract Layer) for system hardware. For software, embedded multi-task kernel is introduced as the platform for development. HAL shields complex detail of low-level hardware, and supplies stable and friendly user interface to high-level software. The introduction of Multi-task Kernel reduces the difficulty of system design, and makes target system possess better performance. At last, the article analyzes and designs EMC ( ElectroMagnetic Compatibility ) for target system to enhance its reliability and the ability of anti-disturbance.
