Peak regulation control method and device based on water use curve

Abstract

The invention relates to a peak regulation control method based on a water use curve, and the method comprises the following steps: obtaining historical water data, and generating a water consumptionmode curve through a water curve model; generating a water tank liquid level target curve through a liquid level curve model based on the water consumption mode curve; adjusting the opening degree ofthe adjusting valve in different time periods by combining the actual liquid level data of the water tank, and adjusting the opening degree of the adjusting valve to continuously approach to the target liquid level according to the check difference between the stage target of the water tank liquid level target curve and the actual liquid level data. The invention further relates to a peak regulation control device based on the water use curve. The regulation and storage capacity of the water tank can be fully utilized, and water for residents is guaranteed.

Description

Technical field [0001] The present invention relates to the field of water control technology, and more particularly to a peak control method and apparatus based on water curve. Background technique [0002] With the acceleration of China's urbanization process, the high-rise residential is the advantageous, the secondary water supply is increasing, and the residential water exhibits a typical morning and evening peak water characteristics. As the population continues to increase, the peak gap is increasingly, the water plant and water supply line Relatively fixed, difficulty, so when the peak is used in the water, the amount of water is too high, resulting in the unstable water supply pressure, drastically fluctuated or the end flow rate, and there is no water to use; when using water, water, water tank, water tank Water quality problems such as excessive long, dead water are not obtained. In order to ensure the stable transmission of the pipe network, the uninterruptible water ...

AI Technical Summary

Problems solved by technology

[0004] The water inflow to the water tank is controlled by the float valve. The float valve opens as the water level of the water tank drops. The water tank starts to fill up with water, replenishes as it is used, and goes in and out at the same time. This type of control mode cannot control the water tank according to the water law. Therefore, the liquid level of the water tank is always at a high level. On the one hand, it brings about water quality problems caused by too long water age, and on the other hand, it cannot effectively use the storage capacity of the water tank, which leads to problems such as peak water shortage and trough water retention.

[0005] The water intake of the water tank is controlled by a solenoid valve, which can only be controlled remotely based on manual experience or simple peak-shaving instructions, and cannot intelligently adjust the strategy according to the law of water use, resulting in poor peak-shaving effects; secondly, the solenoid valve only has two states: open and closed , the precise adjustment of the valve opening cannot be achieved, the fineness of the water tank adjustment is not enough, and the flexibility of adjustment and storage is not high
