AI Technical Summary

Technical Problem

When faced with fluctuations in visitor traffic and water demand, the existing static scheduling method for rainwater utilization systems in commercial complexes leads to improper resource allocation, resulting in excessive consumption or idleness of rainwater resources and affecting utilization efficiency.

Method used

By adopting rainwater dispatching equipment based on sponge cities, water use strategies are dynamically adjusted by obtaining the water demand and storage volume for the current and future dispatching cycles. This includes implementing water-saving strategies when water shortages are predicted, such as adjusting air conditioning temperatures and greening irrigation volumes, to ensure that water storage is optimized across cycles.

Benefits of technology

It enables cross-cycle optimized scheduling of rainwater resources, improves rainwater utilization efficiency, solves the problem that static scheduling methods cannot cope with dynamic changes in water demand, and realizes intelligent and refined management.

Abstract

The invention discloses a rainwater utilization method and system based on a sponge city, a medium and a product, and relates to the technical field of sponge cities. The method comprises the steps that the air conditioner cooling water demand and the low-water-quality water demand of the commercial complex in the current dispatching period are obtained; on the basis of the weather data of the current scheduling period, the rainwater inflow is calculated and predicted in combination with the catchment area and the runoff coefficient of the commercial complex; determining the predicted water storage capacity of the current scheduling period; obtaining a water demand and a predicted water storage amount of a next scheduling period; and when it is predicted that the water amount in the next scheduling period is insufficient, executing a rainwater-saving utilization strategy in the current scheduling period, including calculating the minimum cooling water demand and the minimum greening irrigation water demand, preferentially making the predicted water storage amount meet the minimum water demand, and storing the remaining water storage amount to the next scheduling period. According to the method, the problem that a static scheduling method based on fixed water level classification cannot cope with water demand fluctuation is solved through prospective prediction and a dynamic saving strategy, and efficient utilization of rainwater resources is achieved.
