Description

Remote intelligent meter recording system
Technical field
The present invention relates to the intelligent wireless communication, particularly relate to remote intelligent meter recording system.
Background technology
The meter reading method of present water, electricity, coal three tables still adopts the mode of manual metering, not only brought inconvenience to the user, and order takies the great amount of manpower resource, causes the problem of difficult charge; Emerging IC-card technology overcomes the above problems comparatively up hill and dale, but also very convenient concerning the user buys " water, electricity, gas ", the use information with the user also can't obtain real-time communication simultaneously, so intelligent meter data recording and security monitoring become the direction of industry development.Carry out intelligent meter data recording and security monitoring and just must build the network of transmission data.Traditional data transmission mainly contains data radio station, dialing, satellite communication and lays special line etc., problems such as these transmission modes exist that coverage is little, real-time is poor, investment and operating cost height.The development of GPRS technology and internet Internet technology is for the data transmission and the data network management in industrial monitoring, remote measuring and controlling field provides wide platform.
Automatic data logging technology (Automatic Meter Reading) is that automatic data collection, transmission and processing are applied to a new technology in tap water, electric power, combustion gas (hereinafter to be referred as water, electricity, gas) supply and the management system.It has fundamentally overcome the drawback of traditional manual metering pattern, brings new hope for the management modernization of water, electricity, gas.
Along with water, electricity, gas market management continuous development of the reform, will become focus and direction to the automatic data logging Study on Technology.Abroad, to automatic data logging Study on Technology starting early and more deep, the production from the formulation of standard to the special chip of checking meter is comparative maturity all.In north america such as North America, Canada, Automatic meter reading system is widely used in checking meter among the management system already.Automatic data logging has become a new branch of industry, has many well-known manufacturers to produce the AMR series of products abroad, and also more and more deep to the research of AMR.The U.S. has just set up automatic data logging technological associations (AMRA) in 1986, set up European automatic data logging technological associations (EUROAMRA) and Britain automatic data logging technological associations (UKAMRA) in recent years again.The automatic data logging The Application of Technology has basically formed scale in some developed countries.
All in all, present meter reading method both domestic and external can be divided into manual mode, prepayment mode substantially (by the user by buy magnetic card, IC card etc. in advance to administrative authority, by purchase volume power supply, need not operating personnel and reach the spot), semi-automaticly check meter, automatic data logging mode etc.
China starts late to the automatic data logging Study on Technology, and that is that all right is ripe for technical standard, but country pays much attention to the development of automatic data logging technology.Clearly propose in Ministry of Construction's " fairly well-off urban and rural housing scientific and technological industry engineering city demonstration quarter planning and design criterions (revision) in 2000 ": " applying outdoor metering (moisture, electric, warm, gas meter, flow meter) technology ".In " Chinese dwelling house production development outline ", also clearly propose: " realize conveniently tabling look-up, do not disturb resident family, make the work of manually tabling look-up in a large number progressively carry out the transition to digitizing and transmit the water, electricity, gas of developing intellectual resourceization, heat metering device and interface box-frame ".For now, various meter reading methods all have different research and use at home, but manually meter reading method still is main meter reading method.Though prepayment mode is China's existing use in a lot of areas, this mode needs user oneself to supplement with money, has brought inconvenience to the user, and also has certain defective aspect anti-electricity-theft, should not promote; The semi-automatic meter reading method that cooperates the hand-held collector has been adopted in some area, but still needs artificial the collection, and automaticity is not high; Someone proposes: adopt single table of wired networking or multilist centralized meter-reading system, this need lay netting twine, and cost is too high, and is unfavorable for building installing additional and transforming of sub-district kilowatt meter reading-out system; The somebody proposes power line carrier, PLC automatic data logging mode, but because the power line carrier, PLC quality of channel is relatively poor, is unsuitable for long-distance transmissions, has limited its popularization and development.
Summary of the invention
