Remote quality control system suitable for water quality multi-parameter monitor and using method

Abstract

The invention provides a remote quality control system suitable for a water quality multi-parameter monitor and a using method. The remote quality control system comprises the water quality multi-parameter monitor, a quality control cup, a multi-way valve, a peristaltic pump, an injection pump, a control module, an industrial personal computer, an air filter, a pure water bottle and a plurality ofmother liquor bottles. The pure water bottle, the mother liquor bottles and the air filter are respectively connected to the multi-way valve, the multi-way valve is connected to the quality control cup through a switchable peristaltic pump passage and an injection pump passage, a monitoring pipeline of the water quality multi-parameter monitor is connected to the quality control cup, and a liquidlevel monitoring and overflowing device is arranged in the quality control cup. A second interface at the tail end of the multi-way valve is connected with the pure water bottle; The industrial personal computer communicates with the control module, a quality control system with more complex components is formed, configuration of quality control liquid with various parameters can be provided, solution dosage reminding can also be provided, one system is used, different quality control requirements are met, and the remote quality control system is designed to be modular and easy to expand.

Description

technical field [0001] The invention relates to the field of water quality monitoring, in particular to a remote quality control system suitable for water quality multi-parameter monitors and a usage method. Background technique [0002] During the operation of the water quality multi-parameter monitor, in order to achieve long-term effective and reliable measurement data, regular calibration and quality control are necessary. [0003] There are usually two existing calibration and quality control methods: one is that inspectors bring standard solutions or equipment to the site for manual calibration or quality control, which undoubtedly brings huge workload and labor costs, and cannot guarantee monitoring Long-term reliable operation of the instrument. Another way is remote quality control or online quality control. However, the existing quality control instruments can usually only perform quality control on one monitoring device. If you want to achieve quality control of...

Problems solved by technology

[0003] There are usually two existing calibration and quality control methods: one is that inspectors bring standard solutions or equipment to the site for manual calibration or quality control, which undoubtedly brings huge workload and labor costs, and cannot guarantee monitoring Long-term reliable operation of the instrument

Another way is remote quality control or online quality control, however, the existing quality control instruments usually can only perform quality control on one monitoring device

If you want to achieve multiple parameter quality control, you need to be equipped with multiple devices, which will undoubtedly greatly increase the construction cost, resulting in the inability to be widely used

[0004] In addition, the existing remote quality control or online quality control can usually only be configured with two kinds of solutions, while the existing water quality monitoring equipment mostly has multiple parameter measurement functions

In this case, the existing remote quality control instrument or online quality control instrument cannot meet the quality control or calibration requirements of the water quality multi-parameter monitor

That is to say, the first shortcoming of the existing quality control instrument is that the types of configuration solutions are limited, which cannot meet the needs of water quality multi-parameter monitors

[0005] The second disadvantage of the existing quality control instrument is that it uses a controller, a three-way solenoid valve, a peristaltic pump, a standard addition tank, an air pump, a straight-through solenoid valve, an aeration tube, a liquid level sensor, a waste liquid container, and a liquid dispensing cup. , syringes, syringe brackets, stepper motors and screw sliders, pure water containers, mother liquid bottles, cameras, air filters, air-controlled solenoid valves, refrigeration systems and other equipment to complete the configuration of a quality control solution or standard addition solution, The system is too complicated, the cost is relatively high, and it is inconvenient to maintain
