基于单片机的炉温温度控制系统设计 摘要 在工业生产中，需要对各类加热炉、热处理炉、反应炉的温度进行检测和采用单片机对温度进行控制不仅控制可以，从而能够大大提高产品的质量Design of Furnace Temperature Control System Based on Single Chip Microcomputer Abstract In the industrial production process, often require various types of furnace, heat treatment furnace, reactor temperature detection and regulation, so it needs a proper system of precise control of its temperature. as low power consumption single chip, high performance, reliability, easy-to-market commodity and so on, so to control the temperature using SCM not only save on cost, control method of flexible and diverse, and can achieve higher precision, which can greatly enhance the quality of the product, so SCM is widely used in the Small control system. The automatic control technique is a temperature particularly controls technique at domestic and international get the extensive application with develop. Time postpone effect perplex always in fact on the occasion of applied, for this person invents various controls method to resolve the problem of Time postpone. This paper introduces a design of temperature data acquisition system based on single-chip AT89S52. The system collects temperature data through 1-Wire Digital Thermometer DS18B20, and the control algorithm of DDC parameters is presented. This system according to mold a design for turning procedure design toughing, completing to system software part of designs, giving each function mold piece thought with flow chart. A function temperature control system can proceed accurately the data adopts the kind converts, stabilizing the proceeding heat, the control process of the constant temperature, and can satisfy completely to the request of the system accuracy. and can show them to the operators by the way of the Liquid Crystal Display. This system used the present the usage the LCD and actions output equipments, make data kept the view more. The results of the simulation show that the system works stably and meets the expected design r
