대기오염측정망 원격관리시스템 구축에 관한 연구 = A Study on the Implementation of Remote Management System for Air Quality Monitoring Networks

다국어 초록 (Multilingual Abstract)

Caused by air quality sampling pump networks, results of the studies on solutions of noise and improvement of the work environment, answers in advance for implementing a remote management system , air pollution and air quality monitoring networks time of the inspection and measurement of data reliability and effective management measures for study how to manage are the following.
By attaching Large by pass In-Line Filter in the PM analyzer(R&P, TEOM 1400AB) which is ordinarily thrown away when used for 6 months to one year to sampling extracting pumps and recycling it, the degree of noise has been reduced by 16.6dB(A). In result, suggestion of fundamental solutions of noise and improvement of work environment have been made. Furthermore, with the recycle of used materials, the budget could be reduced.
With gas ventilator idea production establishments of the used gas which is measured in the measurement machinery and tools and then is thrown away, it contributed to PVC(Polyvinyl chloride) material erosion shields which are caused by with ozone where comes out from the workplace improvement and the dioxide nitrogen measurement machinery and tools. And a devide has been developed in order to check the capability of the pumps with outlet tubes.
The Teflon tube and stainless steel pipe used for connection tube between mixture standard gas tank and correction equipment and stainless steel pipe have been tested for 6 months. As a result there was no leakage in the stainless steel pipe compared to the Teflon tube. This stainless steel pipe was used as mixture standard gas tank. So it could avoid leakage of mixture standard gas pipe. Also it reduced disturbance time period of mixture standard gas tank by shortening the length of the pipe.
For the prevention from wrong function of the system which is caused by software related problems but not by hardware related problems of data logger and the minimization of a measurement data discontinuation or being washed away, data logger reset module have been developed for the environment of 100% remote connection and control.
By employing 2-way solenoid valve, it is connected to the condensate issue of compressed air and remotely controlled. The compressed air supply which contains condensate exhaust function that makes condensate water automatically discharged has been developed. Therefore, it has made it possible to create an air pollution measurement network remote system construction environment. In addition, by making the air compressor outlet connected with the 2-way solenoid valve system double, connecting 3-way solenoid valve and having assisting characteristic gas in THC analyzer, the condensate water exhaust device has been developed in order for condensate water not to flow into the meter.
Constructing a remote management system will be able to control both the measuring range of the analyzer and the power of ventilator, which brought work place environment improvement, prevention of the loss of analyzer and finally made it possible to reduce budget.
With the construction of a remote measuring instrument monitoring system, and by monitoring measurement interior environment, the efficiency of analyzer, condition of the analyzer, diagnosis of the broken and its measures and the state of measurement meters at all times, the efficiency and the condition of analyzer are checked without any business trips. After the efficiency and condition of the analyzer and tools are checked, the reliability of measurement data and capability of measurement meter are available by having repair measurement in advance and timely changing the expendable and the degradation materials.
With the Constructed remote reform systems, zero/span drift problems cause by their long time uses are solved by checking zero and span at all times. This has improved the accuracy and a reliability of measurement data.
With remote management system implementation, the case of Gwangju city , it could bring decrease for business trip time for inspection. Generally, it used to take over 30 hours, 4 times a week for inspection. However, it reduced it into once a week and only 4 hours. It also reduced \47,000,000 to \58,000,000 Won every year. Furthermore, if they are installed in 262 measurement path in 16 cities nationwide, it could be reduced \982,000,000 Won or more annually.
