Data Processing and Reporting System for Chemical Analytical Laboratories of Environmental Control

Abstract

The relevance of environmental monitoring and environmental pollution control is justified in the introduction of the article in order to monitor the state of the environment and its protection, on the basis of existing regulatory legal acts. Fundamental principles of these types of environmental activities are given. In order to justify the task, a brief description of chemical analytical laboratories (hereinafter referred to as HAL) activities and the tasks of their information systems is provided. Having analyzed a number of HAL information systems operating in the Russian Federation the authorscame to the conclusion that they mainly perform the functions of automated collecting, storing and processing information. The availability of decision-making support systems (DSS) function in the systems has not been established, for example, none of the software systems issues recommendations on changing the measurement regulations in cases of exceeding permissible values. An information system for data collection, processing and analysis from a chemical analytical laboratory with the DSS functions (monitoring changes in measurement regulations and monitoring the timing of metrologicaldevice verification) is proposed. The article describes the main functions of the proposed system available to the user and the administratorin detail. An example and a detailed description of the regulation changing process based on the MPC excess in samples are given. Regulations, the main blocks of the system, their functions and capabilities are described. The program structure and the system algorithm are presented. All system functions have been successfully tested. The figures show the algorithms of user’s and system administratoractivity when testing the database function, the function of reporting on specified parameters to obtain information about the discrepancy between samplenumbers and devices to the specified parameters, the function of automatic sampling and adding samples from the selected device and the function "Changing the rules". In conclusion, it is emphasized that this information system allows not only data processing from research results of chemical analytical laboratories in an automated mode, but also to perform certain functions of decision-making support systems.
