This paper introduces is the focus of the data acquisition system, and the system hardware part is the center of gravity of the microcontroller. In this paper, the more temperature gathering system for example, DS18B20 temperature measuring system is based on AT89C51 single chip microcomputer as control core, intelligent temperature sensor DS18B20 is the object of control, with LM016L liquid crystal display, using C language implementation of various of system function. Design finished DS18B20 temperature selection screen circuit testing and points. Using simulation tools Proteus and single chip microcomputer Keil software programming realized the system software and hardware, realize the interaction of the topic the design purpose. This subject design temperature control system can realize to the remote environment temperature measurement and monitoring, used in electric power industry, coal mine, fire, high-rise buildings and other places, can also be used for the environmental bad industrial control field.
