Description

A kind of long-distance meter-reading system based on the GPRS+3G communication technology
Technical field
The present invention relates to tele-control system, be specifically related to a kind of long-distance meter-reading system based on the GPRS+3G communication technology.
Background technology
As everyone knows, traditionally for meterage and the management of domestic water meter, ammeter, calorimeter and gas meter, flow meter four table, major part is all that the personnel that take manually copy several modes to indoor: meter reading personnel register one's residence read user use water number certificate, then carry out statistics charging, then charge in user family.There is a lot of drawback in this method:
1. checking meter, labor intensity is large, efficiency is low;
2. leak to copy copies unavoidably by mistake;
3. the cycle of charging from checking meter to is long;
4. managerial cost are high;
5. easily pretended to be by offender, there is potential safety hazard.
The second meter reading method is IC card type prepayment mode: meter reading personnel is without the need to locating to user, and user buys magnetic card, IC card etc. by bank transfer expense or to water resource management department, provides consumption, complete fee collection by purchase volume.It has limitation water, to pay conveniently function, and do not need again to lay spool with water, easy to install.But external a lot of developed country does not advocate this way of paying, reason is that they not think and allow resident because unpaid water rate and lose the right of the most basic water resource of use for the moment.
Remote automatic meter reading system be supervision department be used for industry and domestic water, electricity consumption, with hot and monitor with gas, manage and control, and to the important means that user's consumption situation is added up, analyzed.It is that the data utilizing concentrator to be collected by intellectual water meter carry out preserving, processing, and is connected, can carries out message exchange as requested and between computing machine by network-bus with computing machine.Wherein, the mode that the mode of concentrator collection data of water meter and concentrator are connected with computing machine is divided into wired and wireless two kinds of transmission modes, wherein wired mode input cost is large, needs the data center of laying a large amount of communication lines large-scale with construction to carry out data maintenance.The water meter of current support remote automatic meter reading mode mainly comprises GPRS radio meter register, power line carrier water meter, make a video recording direct reading remote watermeters, Fixed Telephony formula remote transmitting water meter and gsm wireless are checked meter.
(1) GPRS radio meter register: water meter has data metering and processing capacity, data wirelessly (GPRS/CDMA) realize receiving and sending.This type of water meter, without the need to laying-out, is safeguarded with easy for installation, and great majority use the amateurish wireless frequency of international standard and homemade private communication protocol.But because single table installs wireless transmitter additional, the corresponding raising of cost, and often need to change battery, more because take the wireless frequency of charge, also need to pay certain rent and overhead cost; In addition there is the safety problem of data communication, so application is little on current domestic meter market.
(2) power line carrier water meter: under the impact of power line carrier water meter widespread use abroad, China is also continuous technically strives obtaining further developing at low pressure carrier wave, and a lot of mechanism puts forth effort to work out and utilizes low-voltage power line as the intelligent telemetering water meter of communications carrier.But the power line carrier special chip of key is mostly produced by external company, add that the interference ratio of China's electrical network is comparatively large, so can this water meter reliably use also still in discussion, this remote transmitting water meter widespread use be made also to need further research.
(3) shooting direct reading remote watermeters: install pinhole cameras on intellectual water meter, the image of captured in real-time water meter Water usage, because the electric current of water meter is very little, so the wiring time that is convenient, that use is long.Can by hand-held set or wired mode by with the picture transfer of water number certificate to the pulpit in a distant place.But the cost of this shooting direct reading remote watermeters is comparatively large, restricts in actual applications by development condition.
(4) Fixed Telephony formula remote transmitting water meter: because Modern Family's phone uses frequent, the success ratio of incoming call of checking meter is low, and communication efficiency cannot ensure.
(5) gsm wireless is checked meter: wireless telecommunications have a lot of mode, mainly uses at present and utilizes common mobile.Large user has at the electric energy meter, water meter, the gas meter that use the band gsm wireless network terminal, the covering utilizing existing gsm wireless network and the server having installed GSM modulator-demodular unit additional networking are with the object reaching remote automatic meter reading, though reduce construction period and cost, but because the electric energy meter of the band gsm wireless network terminal, water meter, gas meter are due to the price of costliness, cause and be difficult to large-area in resident promoting the use of.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, technical matters to be solved for provide a kind of low cost, small investment, system Construction cycle short, without circuit maintenance cost, reliability is high, transfer rate is high, dirigibility is good, coverage the is large long-distance meter-reading system based on the GPRS+3G communication technology.
To achieve these goals, the present invention adopts following technical scheme:
A kind of long-distance meter-reading system based on the GPRS+3G communication technology, comprise water meter, ammeter, hotlist, gas meter, data concentrator and remote monitoring terminal, described water meter, ammeter, hotlist and gas meter are respectively by a power line carrier modem access low voltage power line carrier communication LAN (Local Area Network), described low voltage power line carrier communication LAN (Local Area Network) is electrically connected with data concentrator by another power line carrier modem, described data concentrator comprises control module, power line carrier modem, GPRS+3G communication module, power supply, storer and clock circuit, described power line carrier modem, GPRS+3G communication module and storer are electrically connected with described control module is two-way respectively, described power supply is that described control module is powered, described remote monitoring terminal is provided with GPRS+3G communication module, is communicated with described data concentrator by GPRS+3G network.
As improvement of the present invention, described water meter and/or ammeter and/or hotlist and/or gas meter comprise the motorized valve of whether closing for controlling it.
