Embodiment 1

[0034] Embodiment 1 provides a digital twin-based intelligent dosing control method for water purification plants, including:

[0035] Based on the physical structure, operation process and historical operation data of the physical dosing room, a digital twin of the dosing room is established; the digital twin of the dosing room is a virtual dosing room model bidirectionally mapped with the physical dosing room;

[0036] Collect the real-time monitoring data during the operation of the physical dosing room through the data collection equipment, and transmit the real-time monitoring data to the management platform through the network transmission system;

[0037] The management platform transmits the real-time monitoring data to the digital twin of the dosing room through the network transmission system;

[0038] Driven by the real-time monitoring data, the digital twin of the dosing room operates synchronously, and dynamically maps the production status of the physical dosing ...

Embodiment 2

[0047]Embodiment 2 provides an intelligent dosing control system for a water purification plant based on digital twins, including: a physical dosing room, a digital twin of the dosing room, data acquisition equipment, a network transmission system, a three-dimensional visualization system, and a management platform.

Abstract

The invention belongs to the technical field of water treatment and discloses a water purification plant intelligent chemical adding control system and method based on digital twinning. The method comprises steps that digital twins of a dosing room is established; real-time monitoring data in the operation process of the physical dosing room is acquired through data acquisition equipment, and is transmitted to the management platform through the network transmission system; the management platform transmits the real-time monitoring data to the digital twins of the dosing room through the network transmission system; the digital twins of the dosing room dynamically map the production condition of the physical dosing room; three-dimensional visual monitoring and display on the digital twinborn body in the dosing room are carried out through a three-dimensional visual system; the management platform predicts the dosage by using an LSTM neural network based on the real-time monitoring data to obtain the dosage prediction information, and obtains the adjustment control information according to the dosage prediction information and the real-time monitoring data; and the physical dosing room adjusts the dosing amount according to the adjustment control information. The method is advantaged in that a problem of serious waste of a flocculation dosing mode in a water plant can be solved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and more specifically relates to a digital twin-based intelligent dosing control system and method for a water purification plant. Background technique [0002] As an indispensable part of production and life, tap water has a large-scale consumption every year. In the water purification process of the water plant, the flocculation and dosing link is the core process in the purification process, and the flocculation and sedimentation effect directly affects the quality of the factory water. However, the current water plants usually add flocculant at a fixed dosage rate in actual operation, and the dosage rate is often too high, which leads to serious waste in the existing water plant flocculation and dosing methods. [0003] In addition, establishing an appropriate mathematical model will be of great help to accurately control the dosage of chemicals and improve the operation level of wat...
