Novel water quality on-line monitoring equipment

Abstract

The invention discloses novel water quality online monitoring equipment which comprises a main controller, a power supply module, an RS-485 communication module, a PH signal acquisition module, a conductivity signal acquisition module and an ORP and temperature signal acquisition module. The main controller is responsible for acquiring digital signals of PH, ORP, conductivity and temperature of water, controlling a frequency generator for exciting external impedance when the conductivity is measured, and interacting and analyzing data and commands with the upper computer; the PH signal acquisition module, the ORP and temperature signal acquisition module and the conductivity signal acquisition module output digital signals corresponding to parameters; and the RS-485 communication module realizes communication of the equipment. Several monitoring parameters are integrated, so that the problem of mutual interference among PH, ORP and conductivity is solved; and all the modules exist independently, data communication is isolated, interference of the external environment is avoided, and the collection precision of all the data and the stability of equipment are ensured.

Description

technical field [0001] The invention belongs to water quality online monitoring equipment, specifically a kind of equipment that realizes online real-time monitoring of PH, ORP, conductivity and temperature in water quality. Background technique [0002] With the development of the economy, the problem of water pollution is becoming more and more serious. All walks of life will face water quality related problems. For example, industrial water systems will face problems such as scaling, microorganisms and deposition during use, resulting in a great waste of water resources and equipment. damage, and eventually the water system cannot function properly. In order to better monitor water quality issues, the state has issued a number of policies to actively promote the implementation of related water quality monitoring. [0003] PH, ORP, conductivity, and temperature are several commonly used parameters in the field of water quality, and are widely used in industry, agriculture...
