Description
Technical field
The invention belongs to the automatic meter reading system of intelligent ammeter field, especially a kind of automatic meter reading system of intelligent ammeter with anti-carrier-in-interference.
Background technology
Intelligent electric meter is just among transformation like a raging fire, and " all standing, the full collection " of low-voltage customer will all realize in 4-5, along with progressively realizing of automatically gathering of low pressure will greatly reduce the check meter input of human and material resources of power supply department.But find in actual use, because the three-phase equipment of low-voltage platform area operation in some 24 hours, as: high frequency water pump etc., meter reading efficiency will descend to some extent, and in order to tackle interference, concentrator can constantly be mended and recruit, change route, namely utilize different intelligent table relaying to check meter, have certain improvement.But because the strong jamming equipment interference strengths such as high frequency water pump are large, and 24 hours hot standby, can produce fatal impact to carrier communication, existing kilowatt meter reading-out system concentrator at zero point every night is by copying and accepting intelligent electric meters all under the concentrator by low-tension supply wire transmission, generally about 300 intelligent electric meters, concentrator constantly circulation is checked meter, the data communication device that the 4:00 AM concentrator regularly will be copied every day cross the GPRS channel issue main website also can be by wired main website that issues.Main website stores data, can login main website by the LAN (Local Area Network) log-on webpage, browses related data, operates.There is interference in institute's carrying device in uploading data because in the circuit, the benefit of concentrator is recruited and trunking mechanism can not play good effect, the rate of copying will greatly descend and generally only have about 60%, through inspection information, find that problems is at low pressure carrier wave field ubiquity, traditional improvement method mainly is to increase concentrator and repeater, not only improved the additional funding input, and only gently disturb the Yuan Tai district certain effect is arranged existing, heavily to disturb the Yuan Tai district helpless to existing, and there is no at home at present effective solution.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of automatic meter reading system of intelligent ammeter with anti-carrier-in-interference is provided, this system architecture is simple, design science is reasonable, and manufacturing cost is lower, and antijamming capability is strong, safe and reliable, the arrival rate of can Effective Raise checking meter.
The present invention solves its technical matters and is achieved through the following technical solutions:
A kind of automatic meter reading system of intelligent ammeter with anti-carrier-in-interference, comprise main website, concentrator, three-phase intelligent electric-energy meter, the power consumer terminal, main website and concentrator communicate, concentrator connects three-phase intelligent electric-energy meter by cable, three-phase intelligent electric-energy meter connects the power consumer terminal by cable, and its cable in three-phase intelligent electric-energy meter and power consumer terminal installs three-phase ac contactor additional, and this three-phase ac contactor is connected with three-phase intelligent electric-energy meter by the space-time switch.
And described main website and concentrator communicate by wired or wireless mode.
And described main website is connected communication with concentrator by optical fiber.
And described main website communicates by letter by the GPRS mode with concentrator.
Advantage of the present invention and beneficial effect are:
1, originally the automatic meter reading system of intelligent ammeter that has anti-carrier-in-interference installs three-phase ac contactor additional at the cable of three-phase intelligent electric-energy meter and power consumer terminal, this three-phase ac contactor is connected with three-phase intelligent electric-energy meter by the space-time switch, when using this kilowatt meter reading-out system, need and power consumer terminal signing time sharing power supply agreement, the emphasis jamming equipment is used this technology, carry out the stopping at fixed time power supply, by to the not power failure of usage time interval of this kind equipment, disturb with check meter time of time period of elimination, thereby greatly improve the rate of copying of low-voltage platform area, allow simultaneously the user economize on electricity, also can play the effect of energy-saving and emission-reduction.
2, the automatic meter reading system of intelligent ammeter that originally has an anti-carrier-in-interference has fundamentally solved check meter a large amount of manpower and materials of dropping into and because solving original follow-up investment problem that the rate problem produces of copying of traditional rural power grids, native system provides guarantee for the efficient stable operation of power information acquisition system, for line loss management and power utility check management provide full and accurate, reliable data, the Marketing management level in raising rural power grids area had important impetus.
3, the present invention is simple in structure, and design science is reasonable, and manufacturing cost is lower, and antijamming capability is strong, and the arrival rate of can Effective Raise checking meter is a kind of safe and reliable automatic meter reading system of intelligent ammeter with anti-carrier-in-interference.
