Data processing system of in-line monitor of environment

Abstract

A data processing system for in-line monitoring water quality and fume is composed of display circuit, watchdog reset circuit, timer, storage, key processing circuit, printer interface, A / D measurer,photoelectrically isolated relay interface, communication interface for remote communication and connecting with network, and single-chip computer for processing input signals, calculation, processing and recording data, dynamic correction and alarm.

Description

technical field [0001] The invention belongs to a measuring device, in particular to an environment online monitoring data processing system. Background technique [0002] Environmental monitoring is a major component of environmental protection work. Environmental monitoring is specifically divided into atmospheric environment monitoring, natural water environment monitoring, sewage discharge monitoring, and waste gas discharge monitoring. As far as the products on the market are concerned, one is the "Environmental Supervision Information System" developed by Xi'an Jiaotong University. This system meets its work requirements from the perspective of environmental supervision, but it has the following deficiencies: (1) Its data processing is based on Every day is the processing interval and lacks real-time monitoring data, so it cannot meet the requirements of environmental management, let alone the requirements of environmental site management and investigation of environme...

Problems solved by technology

As far as the products on the market are concerned, one is the "Environmental Supervision Information System" developed by Xi'an Jiaotong University. This system meets its work requirements from the perspective of environmental supervision, but it has the following deficiencies: (1) Its data processing is based on Every day is the processing interval and lacks real-time monitoring data, so it cannot meet the requirements of environmental management, let alone the requirements of environmental site management and investigation of environmental pollution accidents

(2) Because the system does not have dynamic calibration control and corresponding data processing functions, it cannot meet the online use requirements of current flue gas (atmosphere) monitoring instruments

(3) The monitoring project has been determined to be dead, and new monitoring projects cannot be added, such as the water quality TOC monitoring project proposed by the state, etc.

Among them, the data processor used for water quality monitoring has no dynamic calibration control and corresponding data processing functions; the data processor used for flue gas (atmosphere) monitoring is complicated in its working principle, and each manufacturer uses an industrial control microcomputer to complete the process. Task

Therefore the existing water quality monitoring data processing machine can not complete the network monitoring of flue gas (atmosphere), and the data processing machine of existing flue gas (atmosphere) monitoring is because cost is high, and when being used for water quality monitoring, overqualified and useless, and existing water quality The monitoring data processor cannot compete, and at the same time, compared with the flue gas (atmosphere) data processor manufactured by the single-chip microcomputer, it also has the disadvantages of high cost, complicated use, and short life
