The Design Of Remote Monitoring And Control System For Variable Frequency Constant Pressure Water Supply

People can’t live without water in their daily life, People’s daily water is closely related to the safety operation of the water supply system. Currently, The safety management of water supply system of many living quarters in our country, it still implements security personnel patrol system. It is not only consume time and labor resources, but also it can’t determine the operating conditions of the water supply system accurately. Remoting and unattended safety management system of water supply system, It is the country’s basic requirements in the implementation of the water supply system to monitoring in the future. Therefore, the research of remote monitoring of water supply system has great social significance. In this thesis, Completing the remote transmission technology of the remote monitoring of water supply system with variable frequency and constant pressure, Achieving remote monitoring and control system of water supply system based on WEB and remote monitoring and control system of water supply system based on configuration software. Main research contents of this article are as follows:According to the operational principle of variable frequency constant pressure water supply, design of variable frequency constant pressure water supply system. The design of variable frequency constant pressure water supply system is divided into hardware design and software design. In the part of hardware design, according to the principle of variable frequency constant pressure water supply define I/O variables in PLC and design of water supply control system. In the part of software design, design of variable frequency constant pressure water supply PLC program. In this paper, the design of the hardware module uses STM32 as CPU, achieving the control of variable frequency constant pressure water supply system, system operation data collection and remote data transmission function.For the current mainstream structure of B/S and structure of C/S about the remote monitoring mode. In this paper, Design of variable frequency constant pressure water supply remote monitoring and control system based on WEB and variable frequency constant pressure water supply remote monitoring and control system based on configuration software. According to the structure characteristics of B/S remote monitoring software, using WEB production technology to complete the remote monitoring and control of variable frequency constant pressure water supply system. In the remote monitoring mode of C/S structure, using OPC interface system complete hardware equipment of variable frequency constant pressure water supply system communicate with configuration software, implementing the remote monitoring and control of variable frequency constant pressure water supply system.
