基于单片机工业锅炉水位控制系统设计 摘 要 锅炉计算机控制是近年来开发一项新技术，它是微型计算机软、硬件、自动控制和锅炉节能等几项技术紧密结合产物，作为锅炉控制装置，其主要任务是确保锅炉安全、稳定、经济运行，减轻工作人员劳动强度。实行微计算机控制，能对锅炉进行自动检测、自动控制等多项功效。因为我国工业锅炉生产操作水平落后，造成很多大量热能丢失，实践证实，工业锅炉实现微型计算机控制，是锅炉安全生产，提升热效率，节约能源一大创举，也为锅炉生产开辟了宽广前景。 本设计实行三冲量水位控制系统，以锅炉水位为主控信号，蒸汽流量为前馈信号，给水流量为控制器反馈信号。经过单片机控制，使锅炉水位维持在正常范围内，当水位超出上限或下限时，能及时报警并采取对应 方法。 关键词：三冲量控制，汽包水位，锅炉温度 The design of industrial boiler water level control stystem base Single Chip Machine ABSTRACT In recent years ,computer control of boiler was a new technology.It is a union product with the close connection of micro-computer hardware and software, automati control and the energy of boiler-saving technology. As a boiler control devices, their main task is to ensure that the boiler security, stability and economic operate, labor intensity of staff.Using of micro-computer control, the boiler can automatically detect,automatic control, and so on.Since the backward of our contry's industrial in boiler operation production, resulting in many lost a lot of heat.Practice shows t industrial boiler controlled by micro-computer is not only a major undertaking in the boiler safety in production, increase thermal efficiency, energy conservation, but the production of boilers opened up a broad prospect. This design uses the control system of three-volume water level, the boiler water level as main control signal, the steam flow as the feed-forward signal, the water flow as feedback signalwater level by the Single Chip Machine c...
