| As everyone knows, electricity is already people life indispensable things, if therewere no electricity, people’s normal life would be very difficult to continue. Electricityfrom the moment of its birth has become a commodity, from power generation,transmission, distribution, sale of electricity, need staff a lot of cost and large powerenterprises labor time. Electricity as a commodity to commodity trading, which requiresthe measurement of electric energy, need to use electricity the customer, it is an essentialpart of modern electric power marketing system.Electric energy meter reading in the past, need to use tool for electricians andclimbs up the pole, and then open the meter box, for every meter the display power byreading and clearing. However, with the continuous improvement of people’s livingstandard, people’s safety consciousness increases ceaselessly, have few people want to beengaged in this work. From a reading electrical repeatedly efferent had fallen from thepoles of the news event, dangerous visible meter reading work, at the same time accidentfrequency power supply company caused the accident economic loss a lot. For powersupply companies, the traditional manual meter reading cost is too high, not only needreading a lot of staff, and because of the power supply companies can not supervise thestaff, easy to cause the wrong copy, copy, copy to estimate leakage, even staff collusionelectricity customers stealing electricity phenomenon, it directly to the power supplycompany cause capital the loss of. Manual meter reading system has many disadvantages,it has been unable to meet the power supply company interests.The twenty-first Century is the era of rapid development of the computer network,therefore, the relevant professional and technical personnel to put forward ideas for bold,even if is the modern remote monitoring technology, electric energy measurementtechnology and computer technology together, can be achieved for each city and ruralelectricity usage, and has the advantages of high efficiency, timely and accurately, reducepower supply company loss. Power supply company staff can sit in the control roomcomputer of simple operation, convenient, fast and can be calculated accurately andcollection of regional electricity. Therefore conform to the electric power developmenttrend, a design of remote meter reading system has become a necessity. The remote meterreading system is a combination of modern communication technology, GPRS technology and computer technology. The system uses IP packet, the monitoring centerof the collection good power use information through the GPRS network to the powersupply company, thus realized automatic meter reading and remote wireless controlwork.At present, the remote meter reading system software and hardware system, hasbeen through a series of professional testing, and in many areas of our country hasalready been put into operation and use, by the vast number of customers, obtained theaffirmation and support of electric power enterprises. The core technology of remotemeter reading system--GPRS communication technology is studied and analyzed indetail. By the monitoring center network system, GPRS communication network,computer terminal consists of a set of remote meter reading system, the system usesMC55as the design of the carrier, to realize the data transmission between GPRS andInternet, to meet the basic requirements of remote meter reading system, to achieve thedesign goal. After several regions of the trial of the system, the system can accuratelytransmit the data timely, complete automatic meter reading, and can reduce power loss ofinterests, meet the requirements of customers, but also the liberation of the meter readingstaff a large number of traditional meter reading method. |
