Environmental protection water quality remote monitoring alarm system

Abstract

This invention relates to a long-distance monitoring and alarming system of the environmental water quality. It is mainly composed of the sensing detection assembly, the data collecting / processing device, the wireless network communication module assembly and the center station of environmental water quality monitoring. The sensing detection assembly is made up of varies water quality indicating detectors and the corresponding sensor feeler. The data collecting / processing device has the functions of collecting and processing the simulate signals of immediately detected various water quality indexes, and transforming them into digital signals. The monitoring center station has the functions of immediate storing and analysis processing, sending out indicating alarm in time when the condition of above-norm., and in virtue of public radio communication network, carrying out mutual data transmitting.

Description

technical field [0001] The invention relates to an electronic remote monitoring system, in particular to an environment-friendly water quality remote monitoring and alarm system which transmits data information through wireless network communication. Background technique [0002] At present, in the environmental protection monitoring of water quality in river basins, important water sources, and key monitoring sewage outlets, wired monitoring systems are usually used. The main disadvantages are: first, it is difficult and costly to establish a system. In addition to the high cost of laying a large number of communication lines, it is very difficult to install, wire, and maintain after installation in some areas with poor environments; Once a point is detected, a wired communication must be carried out. Several times a day, a wired communication must be carried out. The cost of wired communication is relatively expensive, and the more points monitored by the monitoring center...

Problems solved by technology

[0002] At present, wired monitoring systems are usually used in environmental monitoring of water quality in river basins, important water sources, and key monitored sewage outlets. In addition to the high cost of laying a large number of communication lines, it is difficult to install, wire, and maintain after installation in some areas with poor environments; Once a point is detected, a wired communication must be carried out. Several times a day, a wired communication must be carried out. The cost of wired communication is relatively expensive, and the more points monitored by the monitoring center, the more times of detection per day, and the communication volume. The bigger the cable, the higher the operating cost, which is very uneconomical; the third is that the reliability of the work is relatively poor. Since the transmission line is laid out in the field, it is easily affected by climate and environmental changes, such as aging, breakage, loose joints or lightning strikes, etc. Moreover, in the process of signal transmission, it is also easy to cause cross-connection, external interference signal string-in, etc., and transmission data is inaccurate. , time-consuming, laborious, heavy workload, very inconvenient

Moreover, since there are no functions such as continuous transmission of monitoring data and real-time automatic over-standard alarms, it is not conducive to the monitoring center to track and monitor the evolution of water quality in real time and throughout the process, and to find problems immediately and solve them in a timely manner.
