Design Intelligent Temperature Monitoring System Based on DSP

Abstract

This paper introduces a 1-wire interface intelligent temperature sensor DS18B20's characteristics and working principle. The design of the temperature monitoring system based on DSP processor TMS320F2812 and DS18B20 solved the 8 bit data multi computer communication problems. The software flow chart and hardware structure of the 1-wire interface multipoint temperature measurement system are described. Evidences show that the system is scalable, simple configuration, operation convenient, with reliability and generalizes with practicability.
