Cloud side-end cooperative intelligent water supply control scheduling method

Abstract

The invention discloses a cloud side-end cooperative intelligent water supply control scheduling method. The method adopts a PLC, an edge gateway and a cloud platform as facilities for controlling and scheduling a secondary water supply system, and the edge gateway is internally provided with a switching module capable of switching the PLC to control the work of the secondary water supply system under the fault condition and controlling the work of the secondary water supply system on the basis that the edge gateway is intact. The cloud platform is provided with an operation evaluation unit, an algorithm optimization unit, a PLC cluster program management unit and a data transceiving unit. The edge gateway is internally provided with a secondary water supply control function program management unit, a data acquisition unit, a local PLC and a gateway secondary water supply program management unit. The edge gateway controls the secondary water supply system to work at ordinary times, the PLC is switched to control the secondary water supply system to work under the fault condition, cloud platform related software can output latest optimal control strategy data to the edge gateway and the PLC, the PLC and the edge gateway control the secondary water supply system to work, and the optimal state can be achieved. The purposes of sufficient water supply and energy consumption reduction are achieved.

Description

technical field [0001] The invention relates to the technical field related to secondary water supply, in particular to a method for intelligent water supply control and scheduling in collaboration with cloud, edge and terminal. Background technique [0002] The secondary water supply system is a system that boosts the water pressure of the municipal tap water pipe network through booster pumps, etc., and then outputs it to the homes of residents in high-rise residential quarters, etc., to ensure normal water use for high-rise residents. The booster pump of the existing secondary water supply system is generally controlled by PLC. PLC belongs to a factory production system control method. It has the advantages of simple application and programming, low cost and high reliability. Considering the economy , Many water supply equipment manufacturers use PLC as the controller. When working, the PLC collects data such as water pressure on the user pipeline side and the municipal p...

Problems solved by technology

[0004] In order to overcome the technical limitations of the existing PLC-controlled secondary water supply system, because the control data of the PLC control system cannot be adjusted according to the on-site water consumption, the water supply pressure and water supply volume in the water supply area cannot be guaranteed, and There are disadvantages of high energy consumption, increased operating costs, and impact on the overall service life of the equipment, as well as the disadvantage that the single-use edge gateway control equipment cannot control the working mode of the electrical equipment if it fails. The present invention provides a combination of cloud platform and edge gateway and PLC’s respective advantages, and manage the system through the cloud platform’s overall planning algorithm and related application units with strong analysis capabilities. In the application, the edge gateway controls the working mode of the secondary water supply system by default, and the PLC is a substitute In the running state, when the edge gateway fails, the control line is handed over to the PLC, and the PLC can receive the fault status and automatically switch to the PLC to control the work of the secondary water supply system. The relevant software units of the cloud platform can receive the edge gateway uploaded by the edge gateway and In the PLC control mode, the data such as water volume and pressure collected by the sensors of the secondary water supply system are calculated and analyzed for a long period of time, and then the latest optimal control strategy data is output to the edge gateway and PLC, and the cloud The platform evaluates each water supply program, and can also control multiple secondary water supply systems with similar water supply parameters to share optimization strategy data with PLC, so that the subsequent PLC and edge gateway control the working mode of the secondary water supply system to achieve the best state and ensure sufficient water supply A cloud-edge-device collaborative intelligent water supply control and scheduling method that can also achieve the purpose of reducing costs under the premise
