碩士 === 長庚大學 === 資訊工程學系 === 98 === The research mainly integrates the technology of code rule, data security and wireless sensors, and builds up a completed environmental monitoring information management system to assist domestic laboratories in the automation of procedure management. The environmental monitoring information management system is primarily divided into seven subsystems, which are: 1. Quotation subsystem: It supplies detection quotation list according to customers’ requirement. 2. Trusted subsystems: Based on the customers’ requirement, it draws a commission list and commissions the laboratory to work on customers’ detection project or the project on the quotation list. It can systematically classify data of all levels by the application made code rule in the trusted subsystem. 3. Sampling subsystems: It helps sampling personnel to take samples, collect data and reduce time on the work procedure and receipts filing so as to advance the efficiency of work. It also helps the sampling supervisor by dividing work and inspecting sampled information. Sampling personnel can monitor the sampling sites from remote locations and introduce wireless sensor network technology into sampling subsystems for the long term. 4. Sample collecting subsystem: It helps collecting samples personnel to receive the samples by the use of a barcode to promote the effectiveness of samples collecting and also to confirm and delete samples. 5. Analysis subsystems: It helps analysis personnel to calculate the analysis data and analysis supervisor to divide work and inspect analysis results. It has made a uniform data exchange format and operation pattern for the laboratory, making a formula by itself in the analysis subsystem. 6 Quality control subsystem: It helps quality control personnel to compute quality control data and judge quality control standards and draw quality control chart in order to more easily inspect the historical records. 7 Reporting subsystems: It helps laboratory personnel to make decimals alternative and report printing and it uses watermark encryption algorithms to test identity of the report for preventing alterations to the report. The research conducts two experiments for the purpose of testing the system efficiency: 1. the first experiment is to test files’ uploading and disposing of files at the same time. We learn from the experiment result that the system needs 1.5 minutes for disposing of uploaded files whose quantities are 50, while 100 shares of files need 4 minutes, 150 shares of files need 5 minutes, 200 shares of files need more than 6 minutes and 250 shares of files need nearly 7.5 minutes. 2 The second experiment is to test the efficiency of watermark encryption algorithms. We learn from the experiment result that the watermark encryption procedure that was written by our research institution is in the most stable state when it is executed one by one. It needs about 2 seconds to execute once and the longest waiting time is about 4 minutes if 100 people are uploading files at the same time.
