Problems solved by technology

[0003] 1. Time control method: control the water intake by controlling the switching time of the water pump. This method has very low sampling accuracy due to changes in the smoothness of the pipeline, the height of the installation position, and the pumping capacity of the water pump.
[0004] 2. Liquid level control method: use the liquid level sensor installed in the sampling bottle to detect whether it is full. This method can only be sampled to full at one time, and batch sampling cannot be performed.
Due to the influence of the smoothness of the pipeline and the wear and tear of the equipment, it is easy to produce large errors
[0006] At the same time, the current sampler basically adopts the method of manual inspection. Since the installation location is usually very scattered and may be installed underground, it is very inconvenient for personnel to go and inspect, and it is time-consuming and laborious to realize true automation.

Embodiment 1

[0049] join figure 1 A flow chart of a water quality sampling monitoring method shown, the method specifically includes the following steps:

[0050] S101. Obtain the weight and sampling flow of the sampling bottle;

[0051] S102. According to the weight of the sampling bottle, judge whether the weight of the collected sample reaches the standard;

[0052] If the weight of the collected sample reaches the standard, step S103 is executed.

[0053] S103. Control sampling ends;

[0054] Wherein, the closing of the sampling can be manually controlled by a person, or the valve can be closed by a controller.

[0055] S104. Determine whether the sampling channel is blocked according to the sampling flow rate.

[0056] If the sampling channel is blocked, perform step S105;

[0057] S105. Dredge the sampling channel.

[0058] Specifically, the weighing sensor is used to detect the dynamic weight of the sampling bottle during water filling, so as to control the sampling volume, an...

Abstract

The invention provides a water sampling monitoring method and device. A weighing sensor is adopted as a control sensor, sampling quantity is controlled by detecting dynamic weight of a sampling bottleduring water filling, whether water flow exists is detected under assistance of a flow sensor, and water existence or blockage of a pipe or a water inlet is detected.

Description

technical field [0001] The invention relates to the technical field of water quality sampling, in particular to a water quality sampling monitoring method and device. Background technique [0002] In the prior art, the following methods are mainly used for water quality sampling: [0003] 1. Time control method: Control the water intake by controlling the switch time of the water pump. This method has a very low sampling accuracy due to changes in the smoothness of the pipeline, the height of the installation location, and the pumping capacity of the water pump. [0004] 2. Liquid level control method: use the liquid level sensor installed in the sampling bottle to detect whether it is full. This method can only be sampled to full at one time, and batch sampling cannot be performed. Moreover, the liquid level sensor is also easily affected by impurities in the water, and it is easy to fail and must be cleaned frequently. [0005] 3. Flow meter control method: the water inf...
