摘 要
如今,随着人们生活水平的不断提升,车库已经成为人们在选择居家时的一个不小的考虑因素,也是小区物业提升品质的一个方面。地下车库通风系统则更需要智能化联网控制。
针对上述需求,本文结合一个科研项目,提出了一种基于自动检测技术、计算机网络技术和智能控制技术的分布式主从测控网络,来实现对地下停车库CO气体浓度自动检测和调节,并监视地下车库温度的解决方案。本系统结合地下停车库通风系统的特征,在前人的经验基础上,首次将自动控制技术应用于通风系统这一难以建立数学模型的被控对象上,设计了以MSP430单片机为控制核心的智能型通风控制系统。
本文主要研究如何在尽可能节约能源的前提下,结合地下车库的特点,研究开发了一个基于RS-485现场总线,以MSP430单片机为控制器的地下车库智能控制通风系统。该控制系统能进行地下车库内环境参数的采集,并将数据发送到上位机,再通过继电器电路控制诱导风机最佳运转时间,从而调节地下车库内环境参数,达到最佳的节能效果。系统具有CO浓度检测、CO浓度状态显示及温度检测、温度显示等功能。

ABSTRACT
Nowadays,with developing of the consume level,the garage has been one of the factors which determine people choose the house where they live,and one way the district upgrade its quality.Underground garage need intellectualized network control ventilation system.
In response to these needs, this paper, a scientific research project, proposed based on automatic detection technology, computer network technology and intelligent control of distributed master-slave control network, to achieve the CO gas concentrations in the underground parking automatically detect and adjust, and monitor underground garage temperature solution. The system combines underground garage ventilation system characteristics, based on the experience of predecessors, the first time, automatic control technology in the ventilation system that is difficult to establish the mathematical model charged object is designed to control the MSP430 MCU core Intelligent Ventilation Control System.
In order to solve saving energy sources problem,the author aim at thecharacteristic of underground garage,utilizing the result of the research, designed a intelligent ventilation control system which is based on RS-485 bus master-slaver supervisory network,which the controller is MSP430 micro-controller produced by TI.The system can do obtain environment parameters(concentration of CO)of the underground garage through a micro-controller linked with the sensors.Then the data are transmitted into the upper computer and with automatic control method transformed into time length signal,with which a motor is controlled to adjust the concentration of carbon monoxide,then regulate the inner environment of the underground garage.
Keywords: Underground garage No wind induced ventilation Data Acquisition System Master-Slave Control Network
