Embodiment 1

[0060] Such as figure 1 As shown, the present embodiment 1 provides a method for dynamically distributing sewage in multiple pools, comprising the following steps:

[0061] Step S1, selecting fuzzy input and output quantities;

[0062] Step S2, setting a suitable fuzzy subset, and performing semantic fuzzification on the input and output quantities;

[0063] Step S3, determining the membership function of the input variable according to self-adaptation; and

[0064] Step S4, establishing a fuzzy rule table for water valve opening.

[0065] Specifically, the method for selecting fuzzy input and output quantities in the step S1 includes:

[0066] Select the amount of sewage Q in a sewage treatment tank, and Q∈[Q min ,Q max ]; sewage treatment complexity C, and C∈[C min ,C max ] are used as the input of the fuzzy controller; and the opening degree Φ of the water valve connected to the sewage treatment pool is selected, Φ∈[Φ min ,Φ max ] as the output of the fuzzy control...

Embodiment 2

[0111] Such as figure 2 As shown, on the basis of embodiment 1, this embodiment 2 provides a sewage treatment system, including: several data acquisition modules for detecting the corresponding component content of sewage in the sewage treatment tank, each data acquisition module will collect each The component content is sent to the host computer; the host computer is suitable for judging the treatment progress of each sewage treatment tank according to the corresponding component content of the sewage in each sewage treatment tank.

[0112] exist figure 2 In each natural village, one or more sewage treatment pools can be set up, and multiple nearby sewage treatment pools can form a local sewage treatment network. The data acquisition module is located at the sewage collection sites of each natural village and collects data in real time through nodes. The ellipse represents the local network formed by multiple sewage treatment pools in each natural village, the circle repr...

Abstract

The invention relates to an adaptive-control multi-pool sewage dynamic distribution method and system based on a fuzzy rule, and the method comprises the steps: S1, selecting fuzzy input and output quantities; S2, setting a proper fuzzy subset, and carrying out the semantic fuzzification of the input and output quantities; S3, determining a membership function of an input variable according to self-adaption; S4, building a fuzzy rule table for water valve opening degree. The method and system achieves the adaptive adjustment of sewage treatment through fuzzy control, and can effectively speed up the speed of sewage treatment. Moreover, the method and system enables a sewage treatment pool with a high speed of sewage treatment to obtain more water based on the connection of a plurality of sewage treatment pools, enables the sewage treatment pool with a low speed of sewage treatment to obtain less sewage properly, and improves the overall speed of sewage treatment, thereby achieving the intelligent adjustment and control.

Description

technical field [0001] The invention relates to a rural sewage intelligent network architecture, monitoring and control system, in particular to a multi-pool sewage dynamic allocation method based on the Internet of Things and fuzzy self-adaptive rules. Background technique [0002] With the continuous development of urbanization and industrialization, industrial wastewater and urban domestic sewage continue to increase. The amount of domestic sewage generated in rural China is about 8 billion per year, and most rural areas have not adopted any domestic sewage collection and treatment measures. Therefore, a large amount of rural sewage discharge is an urgent problem to be solved. It not only seriously affects the living environment in rural areas, threatens human health, but also restricts the improvement of my country's water environment and overall quality. [0003] The composition of rural and village sewage is relatively fixed, mainly containing organic matter such as ca...
