Multi-Channel And Real-Time Data Acquisition And Processing System On Field Test

With the development of national agriculture, the market puts forward new requirement on the quantity and quality of products of agricultural machinery. We must improve their capabilities and empolder new products to accord with the demand of market. Field test provides strongly gist for this project, but high-speed data acquisition and processing become one of the technological difficulties of the solutions to the above problems. In virtue of agricultural computer technology, and combining the special characters of the field-testing to a disc plough, this paper empolders multi-channel and real-time data acquisition and processing system based on a mobile computer. The keys of this system consist of three parts: confirmation of sampling frequency and read-write control of ports; synchronization of multi-channel and real-time data acquisition and processing; the method of data memory and processing. This paper adopts VC++ as software development tools and designs the reasonable hardware configuration. This makes the key problems solved well.At last, the system is carried out to the field-testing of a disc plough to the point. The outcome of experiment proves that the system is credible and efficient. It can be as a kind of test means of a disc plough experimentation.
