Air Environment Quality Testing Methods And Monitoring Software Design

With the development of social economy and cities, the pollution of the city atmosphere is becoming more and more serious. This situation has called out great attention. It is of great value either in theory or in reality to research the detecting methods of air pollutants and establish auto air monitoring systems which is of high quality.This paper first does an analysis and research work to the detecting methods of the air pollutants, and then designs and develops an auto air monitoring system. The main fruits are as bellow:Made a detailed analysis to the sorts and harms of the main air pollutants;Combining with the "Air Pollutants Detecting Methods Criterion of the Nation" studied the common detecting methods and the makeup of the typical detecting apparatuses.Designed and developed a highly intelligentized "air quality auto monitoring system" which is based on the new advances in computer, internet, telecommunication, on-line detecting apparatus etc. It is a system that integrates real-time-data-obtain, intelligence, network and systematization. The system constructed with a multi-nodes-and-layers structure is made up of 3 parts: a high intelligent auto spot monitoring system, a one-to-multi faraway monitoring system, and a group of data transfer software which is based on the Client/Server mode.The network of the system can transfer data by many ways such as Ethernet, modem, radio-communication etc. Combing with the measures such as CRC-checkout, order-affirmance, overtime-resend and Des-encrypt, the validity, reliability and security of data transfer are guaranteed. Besides, in order to make the manipulation more convenience, we designed the human-machine-interface in specific ways for different users.The system has successfully implemented the initial requirement and shown great advantages in validity, reliability, security and efficiency. It has been in use in many cities and towns in ZheJiang province .The "air quality auto monitoring system" has received good comments from many aspects and passed the check-and-accept of the users.
