Description
Technical field:
The present invention relates to the communications field, specifically is a kind of gas meter, flow meter remote meter reading method, system and intelligent gas meter.
Background technology:
The remote meter reading mode that is used at present gas meter, flow meter generally has following 3 kinds:
1, RS485 bus meter reading method, be illustrated in figure 4 as a kind of bus ammeter processed, water meter and gas meter, flow meter three table kilowatt meter reading-out systems, its gas meter, flow meter kilowatt meter reading-out system forms the gas meter, flow meter network of checking meter by intelligent gas meter+data collection station+computer administration center+internet, the present comparative maturity of this technology, in maintenance and easy construction complete execution system is arranged, but its shortcoming also clearly, it is to adopt the form of wired network to carry out the transmission of data, wiring is comparatively complicated, cost is higher, construction is complicated, quantities is large, and also be difficult in the place that is difficult to connect up to use, and each communication link needs to have the IP address, and because and the internet ease of connection attacked by the hacker distorting user data, security is relatively poor.
2, that a kind of WLAN (wireless local area network) adds the ammeter that the internet forms such as Fig. 5, the remote meter reading network of water meter and gas meter, flow meter, to carry out radio communication with point-to-point form between gas meter, flow meter and the home gateway in this network, belong to typical WLAN (wireless local area network), home gateway is connected with the internet by network interface card, gas company is just checked meter to gas meter, flow meter by the internet like this, its defective is: each user must join the internet, perhaps by cell server is set, each user is connected with cell server, the upper internet of cell server connection, so just there are equally handling cost and the higher problem of equipment cost, and each communication link needs to have the IP address, will be connected with the internet equally, attacked by the hacker and distort user data, security is relatively poor.
3, that a kind of employing mobile communication module carries out ammeter such as Fig. 6, the meter register method of water meter and gas meter, flow meter, it adopts gsm module directly to be contained in the gas meter, flow meter, by mobile public network directly and gas company carry out the meter register method of data transmission, this method need to be installed gsm module in each gas meter, flow meter, namely each gas meter, flow meter needs an independent account, this not only needs a large amount of gsm modules, more need a large amount of mobile communication accounts, cost is higher, and take mobile communication account resource, the account resource can become the bottleneck of Mobile Communication Development naturally, and feasibility is too low.
4, also having a kind of is to adopt minisize pick-up head to aim at gas meter counter, then by vision cable video signal is transferred to gas company and realizes remote concentrated ammeter reading.The equipment that this method needs is more, and cost is too expensive, more inadvisable.、
In sum, requirement according to present Internet of Things, be badly in need of now a kind ofly not depending on the internet, security is higher, and do not need too much IP address, do not need too much mobile communication account resource, lower-cost Gas Meter Reading System, meter register method and the intelligent gas meter that is applied to this kilowatt meter reading-out system.
Summary of the invention:
The technical matters that the present invention will solve is, a kind of internet, safe that do not depend on is provided, and do not need too much IP address, do not need too much mobile communication account resource, lower-cost gas meter, flow meter remote meter reading method, system and intelligent gas meter.
