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.
