Design Of Indoor Environmental Quality Monitoring System Based On ARM

Since the reform and opening up, the economy has been presenting rapid andsteady development in our country, the resulting environmental problems have becomethe focus of attention. Among them, the Indoor environment is the prominent one. Thequality of indoor environment will directly affect people’s health and productivity,therefore, it comes very important to design a real-time monitoring equipment ofindoor environment quality status.This topic experiments on the platform of total heat exchanger fan, which is in thelaborary of Intelligent buildings and Building Automation of Xi’an University ofArchitecture and Technology, and designs the indoor environment quality monitoringsystem based on ARM. This system will real-time monitor the indoor environmentalfactors and comprehensively evaluate its air quality level. While the indoor air qualitystatus is "poor", this system will timely remind people of preventive measures, andautomatically trigger the total heat exchange ventilator for indoor environmentalquality improvement.This article firstly describes several important factors that influence the quality ofindoor environment, and gives a brief introduction on the related technologies andresearch status at home and abroad; secondly, with the theory of intelligent control, theindoor air quality evaluation algorithm is presented based on genetic neural network;thirdly, combining with actual cases, the genetic neural network model for indoor airquality evaluation is implemented, and Matlab simulation is carried out for verification,results show that, this algorithm can well grade the indoor air quality situation,sequence the different room air qualities in level. and provide the reliable basis for thenext chapter of the intelligent control; afterwards, they are all introduced whichincluding the overall design scheme of the system, each sensor module, ARM embedded system, and the total heat exchange hardware interface design of fan;Finally, the embedded and integrated environment ADS1.2is adapted to write softwarein this paper and test the entire device, test results show that the monitoring system hasstrong availability...
