Self-maintenance multi-parameter water quality monitor

Abstract

The invention discloses a self-maintenance multi-parameter water quality monitor, which comprises a shell, detection sensors, a monitoring control module and a water injector arranged in a shell body of the shell and used for cleaning the detection sensors, wherein a control terminal of the water injector is connected with a cleaning control terminal of the monitoring control module; the detection sensors are various water quality physical parameter sensors, and signal input / output terminals of all the sensors are connected with corresponding detection ports of the monitoring control module respectively; the monitoring control module is also provided with a communication interface which is in communication with an external upper computer; the shell is provided with an opening, water to be tested outside enters the shell body from the opening of the shell to submerge and contact all the sensors, and the monitoring control module controls the detection sensors to detect and acquire parameter signals of the water quality and then is in communication with the external upper computer through the communication interface; and meanwhile, the monitoring control module controls the water injector to inject water to wash and clean the detection sensors. According to the self-maintenance multi-parameter water quality monitor, the water quality physical parameters are monitored continuously and precisely in an online manner.

Description

technical field [0001] The invention relates to a water quality monitoring technology, in particular to a self-maintaining multi-parameter water quality monitoring instrument. Background technique [0002] Water quality monitors can be specifically applied to rivers, lakes, reservoirs, groundwater, and water supply plants, and are also widely used in industrial discharge detection and sewage treatment plant monitoring. [0003] At present, the automatic monitoring of water quality mainly relies on the automatic monitoring system of water quality. A water quality monitoring network is formed by building multiple automatic monitoring stations to monitor three types of water quality (sewage, groundwater, and surface water). Although the water quality monitoring system plays an important role in the monitoring of sea, river, groundwater, etc., due to the huge size of the water quality monitoring system, it takes a lot of manpower and material resources to maintain.
