Based On At89s52 Temperature Measurement And Control System Design And Implementation

In recent years, with the development of the technology of communications, computer and sensor, it is possible to control remote temperature in real-time by using technology of collecting remote data. Temperature measuring system is the international hot field, which involves sensors, computer, communications and other subjects in various fields. The Based on AT89S52 temperature measuring system designed in this paper has the advantage that is out of the effect of geography,climate,time. By using transmission, the system also has more advantage such as lower cost in project, lower humanity resources, high reliability and free of maintenance, etc.This system mainly realizes the measurement for multi-point temperature and the communication with upper computer. This paper described the design idea and the realization method, analyzed the design principle of every part and introduced the design process in detail. This Based on AT89S52 temperature measuring system make up of the part of collecting data, transmitting data and the communication among upper computers. The collection part use low-power and high-performance CMOS 8-bit single chip AT89S52 as control center,used the temperature sensor DS18B20 sending the collected T data to single chip to be processed. Because of the most temperature control system on market today is controlled by a temperature high or low, few based on time control regulation and control. We have included in the hardware design of timing control, that you can set the system in the work within the stipulated time,which in order to increase the security of the system.
