THE STUDY ON AN AUTOMATICMEASURING AND CONTROLLING DEVICE

摘要

In this paper design of hardware and software of the multifunctional agricultural meter is presented. Its controlling center is based on the new type Micro-controller AT89C52. In the A/D converting stage the V/F converter is used and the sensors, which are reliable, cheap and satisfactory to the accuracy, are used. Therefore the system has features such as simpler interface, stronger antjamming feature, more adaptive distant transmission, better measurement accuracy and better control reliability. The system can be applied extensively in the agriculture.
