摘  要 [来源:http://www.think58.com]

我国持续、快速的经济增长和人民生活质量的改善,对环境控制提出了更高的要求。对环境温度自动监测、环境污染治理作为环保产业的重要内容,在我国已大力展开,无论在理论上还是在实践上都取得了很大进展。为系统运行服务(自动检测、优化、控制)的控制理论,在环境监测、环境治理中应扮演怎么样的角色呢?我们将环境监测、环境治理过程的自动控制技术称之为环境控制自动化。环境控制自动化对从事控制理论研究的研究者来说,是一个新的应用领域,也是极有发展前景的领域,环境控制自动化的研究不仅具有重要的理论意义,也具有重大的实际应用价值。 [资料来源:www.THINK58.com]

本文主要介绍了由数字温度传感器DS18B20与89S51单片机组成的恒温控制报警系统的组成及其工作原理。

Abstract

Our country continually, fast economic growth and the lives of the people quality improvement, set a higher request to the environment control. To the ambient temperature automatic monitor, the environmental pollution government took the environmental protection industry the important content, has launched vigorously in our country, regardless of in theoretically has all made the very big progress in the practice. Serves (automatic detection for the system movement, optimization, control) the control theory, in the environmental monitoring, how role the environment government should act? We the environmental monitoring, the environment government process automatic control technology call it the environment control automation. The environment control automation to the researcher which is engaged in the control fundamental research said that, is a new application domain, also is has the prospects for development extremely the domain, the environment control automation research not only has the important theory significance, also has the significant practical application value.
