Abstract

The invention discloses a device and a method for sampling suspended matters based on a LabVIEW upper computer. The device comprises an upper computer, a lower computer, a suspended matter collecting device and an RS485 serial port communication module, wherein the lower computer comprises a single chip control module, a data conversion module, a pressure sensor measuring module, a turbidity sensor measuring module and an electromagnetic flow meter measuring module; the upper computer is connected with each module of the lower computer through the RS485 serial port communication module so as to realize the real-time collection, transmission, display and storage of underwater depth, concentration and flow data; the upper computer sends an operation instruction to the lower computer through the RS485 serial port communication module and is used for automatically controlling the data collection process of each sensor and the sampling process of the suspended matter collecting device so as to realize the automatic sampling for a suspended matter sample. The device is simple and convenient to operate and is portable; the LabVIEW upper computer interface is reasonable to design; the problem of complex operation of the present sampling device is avoided; the degree of automation of the whole sampling process is increased.

Description

technical field [0001] The invention belongs to the technical fields of environmental monitoring, environmental governance and computer control, and in particular relates to a suspended matter sampling device and method based on a LabVIEW host computer. Background technique [0002] Suspended solids in water refer to certain substances suspended in water, mainly including inorganic substances, high molecular organic substances, sediment, clay, protozoa, algae, bacteria, and viruses. As the main source of daily water for local residents, water source reservoirs in various places have played a pivotal role in human society for a long time. During the water storage and water supply operation of the water source reservoir for many years, the state of suspended solids in the water body is also constantly changing. Among them, suspended solids with larger particle sizes gradually settle to the bottom of the reservoir, while those with smaller particle sizes are gradually adsorbed...
