Study On Constant Pressure Water Supply Remote Monitor And Controlling System

With the development of the radio telecommunication technology, the computer network technology, the VF speed regulation technology of AC motor, the SCM technology, the controlling level of water supply industry experiences a revolutionary leap. This paper bring forward a new water supply system—constant pressure water supply remote monitor and controlling system basing on VF speed regulation constant pressure water supply system of exiting. It has telecommunication function, remote measuring and controlling function and fault diagnosis function .It can not only control according to the fact of consumer in the distance to solve the contravention of water supply pressure not enough ,but also found fault of it in time. I believe this system will be the development current of water supply system.This system takes the GPRS modem, which was studied and designed by myself ,as its communication equipment. GPRS modem , whose design method is in the bud and secret phase ,is currently one of the most hot and new communication technology and its design and application are the research emphases and innovation point of this paper. This paper considers fully maneuverability, reliability and cost of the GPRS modem. Both the reliability and cost of the GPRS modem are keeping ahead. It designs high-powered communication for constant pressure water supply monitoring and controlling system. In addition, the GPRS modem can apply other fields, such as instrument and meter. This paper introduces in detail not only its design of hardware and software but also its application in water supply system.Because the function of this system is mightiness, the signals, which need measure, include pressure, flux, temperature, vibration, he height of liquid, rotate speed. This paper designs theirs measure circuit and dealing with method of software. This paper also discusses the VF speed regulation technology of AC motor and the fault diagnosis technology.The GPRS modem , which this paper studies and designs ,has application in water supply system and instrument and it works very well.
