Summary of the invention: technical matters to be solved by this invention is, provide a kind of networking simple, expensive cheap, practical, and can get involved the on-Line water quality monitoring network system of various physics, chemical parameters and the total amount of pollutant of ground monitoring water body synchronously in real time, flexibly.
For this reason, technical scheme of the present invention is: a kind of on-Line water quality monitoring network system, be from top to bottom by central station computer, base station computer, three levels of on-line monitoring instrument, under the programmed control of each level is coordinated, interconnect composition by serial line interface, it is characterized in that: the network between described central station computer and described base station computer is gone up formation by modulator-demodular unit at Internet (INTERNET); Network is to interconnect by expansing serial interface to form between described base station computer and described on-line monitoring instrument; The outlet line of described on-line monitoring instrument is equipped with mould/number conversion circuit, is to output to above-mentioned expansing serial interface after the digital signal with analog signal conversion.
Described on-line monitoring instrument comprises water body physical parameter sensor, water body chemical pollutant levels analyser and online flowmeter.
Described water body physical parameter sensor comprises PH instrument, turbidimeter, dissolved oxygen meter, conductivity meter, water temperature sensing instrument; Described water body chemical pollutant levels analyser belongs to automatic photometric titrator or automatic colorimetric analysis instrument, and it comprises permanganate index instrument, nitrite blood urea/nitrogen analyzer, nh 3-n analyser, phosphate analysis meter, sexavalent chrome analyser, total arsenic analyser; Described online flowmeter is Electromechanically integrated.
The program of described each level has two kinds of control models: i.e. total system automatic control mode and manually intervention control model; Described artificial intervention control model comprises three levels intervention controls again: i.e. central station computer intervention control, base station computer are got involved and are controlled, the on-line monitoring instrument is got involved and controlled.
Owing to taked above-mentioned technological improvement, the present invention has following advantage;
Network between central station computer and base station computer is to form by Internet (INTERNET), thereby greatly saved the networking cost, and modulated analog signal is convenient to carry out the control operation of overlength distance, makes water quality and even environmental monitoring Control Network huge system become the reality possibility suddenly; And the outlet line of all kinds of on-line monitoring instruments is equipped with mould/number conversion circuit, with analog signal conversion is the expansing serial interface that outputs to base station computer after the digital signal, in the base station, directly adopt the digital signal contact, make various physics, chemistry and total amount testing tool in the energy united and coordinating control station of base station, and make inner control relatively independent, stable, be not vulnerable to external interference; Control program makes artificial intervening mode flexibly, conveniently, can carry out functions such as data acquisition, result's demonstration, parameter setting, daily record Wen Yin, data transmission, statistic of classification, printing backup, system alarm, command remote control as required.
