Multi-parameter high-precision water quality detection device

Abstract

The invention discloses a multi-parameter high-precision water quality detection device, which comprises a sensor water tank, an overflow plate, a sediment buffer area, a sensor detection area, a water inlet, a water outlet, a water quality analysis sensor set, a lead, a detector, a display screen, a digital signal conditioning module, a temperature sensor, a pH sensor, a conductivity sensor, a dissolved oxygen sensor, a turbidity sensor, an AD acquisition unit, a display device, a power module, a controller unit, a signal conditioning unit and a data communication unit. Each sensor generatesa millivolt-level feedback signal under the action of 12V excitation voltage, multiple characteristic parameters such as water temperature and conductivity can be measured at the same time, and the measured characteristic parameters are conveniently transmitted to the AD acquisition unit for analysis.

Description

technical field [0001] The invention relates to a detection device, in particular to a multi-parameter high-precision water quality detection device. Background technique [0002] Water resources are an important part of natural resources and an important resource guarantee for my country's modernization drive. Both residents' lives and business production require safe water, so real-time online detection of water resources is required. Through the online detection of the conventional characteristic parameters of the water body, the abnormal situation in the water body can be discovered in time, and the early warning can be carried out in time and the detection of other characteristic parameters can be carried out. Routine water quality testing needs to detect routine characteristic parameters such as temperature, pH value, conductivity, dissolved oxygen and turbidity. The pH value indicates the value of the acidity or alkalinity of the aqueous solution; the conductivity is...

Problems solved by technology

Common online water quality detection equipment often uses a single meter to detect a single parameter in a separate way. Multiple parameters require multiple meter heads, and the non-detection data is not concentrated. The meter head has no detection data storage function and historical data query function; and it lacks intuitive and friendly people. Computer interaction interface, powerful data management and maintenance functions and rich data communication capabilities, therefore, to address these problems, a multi-parameter high-precision water quality detection device is provided
