Based On Sms Scheduling Of Urban Water Supply Telemetry System Design

Pipe network as the important part of the urban water supply industry, takes charge of distributing water to users, and ensures the water flow, pressure and quality. The optimization function of the pipe network lies in the application of the monitor and measure system. That is the data acquisition to the every monitor point. So, this problem is worthy while researching.According to the characteristics of wide distribution area, large quantity, long distant and scatter in the urban water supply industry, and the application and development of wireless communication technology, this paper presents a system of wireless data acquisition based on SMS. This system can realize the collection of pipe network parameters automatically. The most important advantage of this system is low cost. This advantage embodies in several points, low investment, low equipment, low consumption and low maintenance cost etc.This paper mainly resolves the problem of wireless remote transmission of data based on the analysis of the theory about short message transmission. The realization of data automated acquisition and transmission will provide the basis for the optimization function of urban water supply industry. The main points of this paper are as follows.1. Communication between monitor computer and SMS block. Monitor center realizes the spot data acquisition and monitor commands transmission by communicating with the Lower-computer.2. Single-chip computer controls the SMS block receive or send the short message. This part sends spot data to SMS block of Upper-computer, and receives the monitor commands.3. Data acquisition system. It can realize the parameters acquisition of pipe network pressure and the flow by single-chip computer system. Then these data are stored by certain formal for transmission.4. Software design about monitor system. According to the simple and directly perceived technological process pictures, workers can operate easily.
