Abstract


With the development of the city and the increase of population, the growing number of users of natural gas, the sharp increase in the pressure of the gas meter reading, and the traditional manual meter reading charges periodic billing management mode can not meet the industry needs, requires a new intelligent meter reading management system to solve the pressure of the gas company. This project to be completed is the view of this situation and the development of intelligent meter reading system, which is based on existing wireless acquisition hardware development meter reading management system. The system is combined with the gas meter reading status quo, on the basis of the existing architecture, state-of-the-art B / S mode, short-range wireless data collection and remote GPRS transmission data, and gas data monitoring, analysis and management. The system mainly consists of a short-range wireless data acquisition part, the GPRS data transmission portion, data analysis and management software portion of this three-part composition. The data collection, the use of state-of-the-art wireless sensor network technology. Dispersed in each household gas meter through the integration node of the sensor, the data processing unit and a communication module, since the composition of a distributed network, via radio waves for data transfer between adjacent nodes, data can also be transmitted via the relay, the formation of a wireless network to cover the entire cell, the data is aggregated to the district's concentrator, greatly increasing the copy pass rate. Data transmission part, the use of advanced GPRS network data transmission technology, GPRS is a system based on GSM wireless packet switching technology to achieve the best combination of user data to the wireless network resources; transparent transmission of IP protocol. Cell concentrator aggregated user data through the GPRS network to transfer the data to the gas company, the data acquisition computer. Data analysis and management software part of the advanced B / S structure, B / S (Browser / Server) structure browser and server architecture greatly simplifies the client computer load, reducing the cost and effort of system maintenance and upgrade, reducing the user's overall cost. Through the computer network, the data acquisition computer data transfer to the database server, data query the server for data analysis, published in the form of a web page, the gas company outlets via a computer network query in the form of a web page and print the payment notice . The entire system is technologically advanced, full-featured, can well meet the demand of gas companies in the current environment work.
