Embodiment Construction

[0016] figure 1 It is the overall structure of the water sample distribution system, which is divided into three levels, namely the embedded control level (I), the bottom control level (II) and the pipeline level (III).

[0017] 1. Embedded control level system

[0018] The embedded control level system consists of an industrial computer, input and output devices, RS232 serial line for communication with the bottom layer, power supply and so on. The embedded control level system is monitored and controlled by the industrial computer, including the control of system tasks, the control of the collection of signals from various seawater analysis instruments, and the upload of data. The state makes corresponding adjustments to the system action to ensure the stable operation of the automatic water quality station itself.

[0019] It can remotely log in to the industrial computer to send remote commands to realize the human control of the equipment, and has the functions of data ...

Abstract

The invention discloses an automatic seawater quality monitoring and water sample distribution system. The overall framework of the system is divided into three levels which are an embedded control level, a bottom control level and a pipeline level; the pipeline level is the main step; an automatic water sampling system adopts a vertical multistage centrifugal pump to obtain water; the original sample water is divided into four parallel paths after entering a raw water pool; the first path enters a multi-parameter analyzer flow channel through a solenoid valve 1; the second path enters a totalnitrogen total phosphorus flow channel through a solenoid valve 2; and the third path enters nutritive salt analysis through a solenoid valve 3, and multistage filtration can be performed before thethird path enters the nutritive salt analysis; the first three paths can be finally discharged through a total path after passing through pressure-regulating valves of respective branches; and the redundant raw water in the raw water pool can be discharged through a pressure-regulating valve 3.

Description

technical field [0001] The invention relates to the field of marine automation equipment, in particular to the field of an automatic sea water quality monitoring and water sample distribution system. Background technique [0002] For quite a long period of time, the water quality sensors deployed in marine environment automatic monitoring stations are mainly multi-parameter water quality meters, and the monitoring elements are mainly conventional indicators such as temperature, salinity, electrical conductivity, Ph, chlorophyll, and dissolved oxygen. [0003] With the further development of the ocean by humans, more and more indicators are required to be measured and monitored, such as nutrients, total phosphorus, total nitrogen, TOC, COD, etc. Therefore, it is necessary to build an automatic monitoring station for the marine environment with complete monitoring indicators, high integration, and high intelligence. Contents of the invention [0004] The technical problem m...
