Abstract


In the process of milk collection and production control, it is needed to measure the content of the main constituents in milk accurately and rapidly. As the content of fat and protein in milk is the key quality index, most of work on the milk quality measure placed emphasis on the measurement of two indexs. Currently, there are several ways to measure the constituents of milk, and they have advantages as well as disadvantages. This thesis presents a new way for measuring milk constituents. The new technology utilizes the scattered light to transmitted light ratio of laser light to determine the amount of protein and fat in milk. In this paper, the main content is the develop process of the instrument for the measurement of the milk constituents based on the 32-bit ARM microprocessor-LPC2210 and embedded real-time operation systemμC/OS-II. And also we expatiate this instrument’s material technology and the technology’s corresponding realization methods.The main research contents of this dissertation include:1. Fundamental theories of this new technology and theoretical model are discussed in detail, based on that, the mathematical model is made by experiments between the scattered light to transmitted light ratio of laser and the content of protein and fat in milk.2. Design of instrument hardware as the ARM architecture microprocessor for core, construction of a microprocessor LPC2210, FLASH memory, SRAM memory, keyboard, LCD, data acquisition modules and temperature monitoring module as one ingredient in milk of hardware platforms.3. Design of instrument software as the embedded real-time operation systemμC/OS-IIfor platforms, completed theμC/OS-IIoperating system to the lpc2210 microprocessor transplantation, as well as related hardware drivers, completed applications in theμC/OS-IIoperation system.After designing and debugging the system to achieve the desired goals. This paper presented their test results. In order to further improve and enhance performance, this paper presents a design and its follow-up study on some of the recommendations.
