The Two-Meter Long-distance Measurement And Toll Management System

Along with the progress of computer network technique and the coming of information times, the intellectualization of resident community and the modernization of way management are developing rapidly. The used way to manage water and coal gas to copy the meter numbers, make data statement, charge and etc. It is obvious that dose not meet the equipment of ruination and intellect utilization. For that reason, we developed a long-distance measure and charge esteem for water and coal gas. This system is a new generation of administrative coal gas. This systemic a new generation of administrative system with automatic measure and charge in city. It is the certain way to speed up the city development. It accords with people's requirement for huge laity life and the state 2000 spirit of "xiaokang"residence industry. With long-distance measure and charge system, we can prevent disturbing people emerged from copying meter number and charging. We also can simplify management and lighten the burden of woe Management.The design principle of long-distance two-meter measure and charge system is provided. The realization method is also explained in hardware and software programming by this article.Firstly, the article introduces the project source, sign finance, present applied situation and developing tendency in domestic and intonation, secondly, provides the theory analysis and technical research in system compose, function design of the system software is expounded in detail. Finally, I sum up the work. I have done and prospect for the future.The long-distance two meter measure and charge system has the function to manage the water meters and coal gas meters. It can record the pulse signals sent from meters, then change them into measurement data and store them into E~2PROM. It has the function to measure and record the two meters faults. The faults include: short-circuit and open-circuit of data communication, man-made destroy and interfere. This system also has network function. It can exchange data with up machine by interface RS485.This system is on probation in somecommunities. It has strong points of accurate real-time, reliable operate, strong extended ability. So it is worth to popularize in communities towards intelligent and modern management.
