Remote metering standard device of online water pollution source monitoring instrument

Abstract

The invention relates to a remote metering standard device of an online water pollution source monitoring instrument. The device mainly comprises an eight-way valve automatic acquiring system, the online water pollution source monitoring instrument, a 4-20 mA analog-digital conversion module, a 3G data transmission module and a terminal server, wherein the eight-way valve automatic acquiring system consists of a control circuit and hardware equipment; the hardware equipment is an eight-way valve; the control circuit comprises an eight-way valve switching circuit module and a serial port communication module; the 4-20 mA analog-digital conversion module converts measuring values of the online water pollution monitoring instrument-output current into digital signals; the 3G data transmission module sends signals transmitted by a communication module to the 3G network, and completely stores in the terminal server through the 3G network. The remote metering standard device improves the quickness and the accuracy of online real-time data monitoring to achieve real-time monitoring of the measuring data, so that the labor force is saved, the daily detecting efficiency is improved, and the automatic management is realized.

Description

technical field [0001] The invention relates to a standard device, in particular to a remote measurement standard device for an online monitor of water pollution sources Background technique [0002] Water is the source of life for human beings to survive. However, with the acceleration of industrialization and the continuous improvement of urbanization, my country has entered a period of high incidence of water pollution accidents, and the shortage of water resources and damage to the water environment have become increasingly serious. Environmental governance and monitoring tasks are becoming more and more important. Therefore, how to protect water resources and effectively monitor the discharge of polluted water has become one of the important national policies for sustainable development of the country.

[0003] Water environment monitoring is an essential part of water resource management. At present, water pollution on-line automatic monitors are usually used to detect water sources. However, the verification of a water pollution on-line automatic monitor often takes one day, and each water pollution The installation sites of the online automatic monitors are far apart. It is quite difficult, even unrealistic, to solve the daily verification tasks of more than 2,000 sets of online automatic monitors for water pollution in the province with the current manpower and material resources.
