Description
Technical field
The present invention relates to tele-control system, be specifically related to a kind of long-distance meter-reading system based on cable TV network.
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.In existing long-distance meter-reading system, generally take mixed transport network mode to realize long-distance meter-reading system, such as, show to adopt M-Bus bus or RS485 bus between tool and collector, between collector and concentrator, adopt small wireless, power line carrier etc.Wherein, the above two kinds of modes of employing carry out the communication between collector and concentrator, and its stability has very large relation with site environment, and its shortcoming is as follows:
1, between reading meter collection machine and meter-copy collector, when distance, adopt power line carrier to transmit data, disturbing can be more serious, make power carrier normal communication apart from closer, in the place that the spacing of ammeter and ammeter is distant, speed of checking meter and reliability are not high, even copy less than table.
2, adopt small wireless to transmit data, but there is multilayer water mud wall due to scene, and the site problems such as distance, cause small wireless complete networking success ratio low, effect of checking meter is bad.
3, the place even cisco unity malfunction that some environment is poor,
4, speed of checking meter is also lower, cannot transmit larger data volume, causes whole Automatic meter reading system to have certain manual maintenance.
