Research And Design On Intelligent Building Water Supply System

At present,with the development of intelligent building in major cities,generally have a higher degree of intelligence,but water supply as an important sub-system of intelligent building automation control system,equipment and water supply due to pipeline constraints,for The water has been relatively backward technology,low degree of automation,with the living standards of a significant increase in people's water quality and supply reliability of the system requirements are rising,so the automatic use of advanced technology to design high-performance,Reliable water supply system is of great significance.This article first analysis of the water supply system in the work of the principle of Frequency on the principle of energy-saving water supply,water supply system for frequency conversion constant pressure control targets accurate mathematical model is difficult to establish,with a system of time-delay and non-linear features,As well as multiple pump runs charged to switch over-voltage generated by the impact of over-current,made use of neural network PID control strategy,as well as simultaneous phase-locked loop switching control strategy.At the same time the needs of the simulation system in order to establish a model similar to the water supply system.PID neural network controller with online self-learning,self-organizing capacity to improve at the same time the traditional neural network learning for a long time and the slow pace of convergence of vulnerability,the traditional solution to the PID control algorithm known less complex systems,using Matlab simulation software,Respectively, the traditional PID control,BP neural network tuning PID control parameters,as well as the use of neural network PID control algorithm of the three control algorithm for the simulation of comparison,the results show that using the neural network PID control algorithm allows water The constant pressure system performance and dynamic characteristics have been improved,control more satisfactory results.In the PLL design,the first phase locked loop described the basic principles of a given phase of the PLL and its mathematical model,and the phase-locked loop performance analysis,using CD4046 constitute a lock-in Loop,given the phase-locked loop control of the synchronous switch schematic.Finally,a design based on the PCC pressure water supply control system using B&R's main control unit for the PCC,the use of the upper IPC,the main station PCC, from the PCC constitutes a multi-station control system,a system for equipment Selection of the PCC and the configuration of modules,and Automation studio to prepare a neural network PID control procedures.PCC and the main station from the station between the PCC use of CAN bus communication.Wang used the software configuration of PC configuration for monitoring the use of B&R PVl,the establishment of Kingview and the main station of communication between the PCC, the design of the site's real-time monitoring data interface.The constant pressure control system can be very good and intelligent construction of other sub-systems together,building water supply has greatly enhanced the level of automation,the system has good control and reliability,will be widely applied.
