Abstract
The management system consists of several terminals, transmission bus, concentrated controller, transmission medium and management computer. The terminals, transmission bus and concentrated controller enclosed in a casing to form a basic unit, and the management computer connected through transmission medium to several basic units forms the management network. The present invention realizes concentrated control of electricity quantity acquisition, processing, storage, display and kilowatt-hour meter state.
Description
Concentrated network type management system for electric quantity of kilowatt-hour meter belongs to collection, the processing of power consumption, the automaton of toll administration.
Existing watt-hour meter generally all is the induction mechanical type, and what the collection of electric weight was carried out is the manual metering mode.Therefore exist inevitably inaccurate, real-time is poor, labour intensity is big, the shortcoming that the input personnel are many.For solving the problem that the induction type mechanical watt-hour meter exists, following several paying watt-hour meter that give appear in recent years, as magnetic card type watt-hour meter, slot meter, single user's electric card type watt-hour meter.But all there is following shortcoming and defect in they, and can not popularize.As magnetic card type watt-hour meter owing to need establish card-reading system, thereby cost height, reliability is low.Slot meter because of coin easily by imitated and must possess coin-feed machine, so be still the cost height, reliability is low, and safeguard difficulty.Though single user's electric card type watt-hour meter is advanced, can finish the automatic collection that user's electric weight gives paying and electric weight, but still have following shortcoming: one, the electricity card is grasped in user's hand, will be blocked by individual subscriber and insert input and the collection that watt-hour meter is finished electric weight, user direct contact ammeter.Therefore, be difficult to prevent power stealing, robber's table and artificial destruction, and form by conventional memory spare, so easily be replicated because of blocking.Two, because of a family one card, difficult management, maintenance workload is big, and is fragile, cost is high.Three, single this height of telogenesis, reduce cost be subjected to table function and limitation of complexity (because of single table to possess data acquisition, storage, to functions such as user's video data, special card).Four, giving further, networking, robotization cause difficulty.
The objective of the invention is to design and a kind of watt-hour meter is adopted the concentrating type structure, and realize electric quantity data is concentrated collection, processing, way to manage.To improve automaticity, accuracy and the real-time of electrical management; Reduce labor intensity, for the user provide intuitively, easily, real-time data with electricity condition.For electric administrative department is implemented the effective management of power use, improve the transparency between electric administrative department and the user, provide effective device for preventing illegal electricity consumption.
The present invention is made up of K terminal, transfer bus, Centralized Controller, transmission medium, supervisory computer.Each terminal is made up of mechanical watt-hour meter, reflective sampling thief, synchronizing pulse sample circuit, data processing and storage circuit, ammeter serial bus interface circuit.The interface circuit of reflective sampling thief, synchronizing pulse sample circuit, data processing and storage circuit, ammeter universal serial bus all is located in the mechanical watt-hour meter.K terminal all linked to each other with Centralized Controller by transfer bus.Centralized Controller is made up of display circuit, central data treatment circuit, clock control circuit, monitoring and reset circuit, controller bus interface circuit, input/output bus interface circuit.K terminal, transfer bus, central controller are arranged in the middle of the housing of a sealing, this unit of primordial.Supervisory computer is communicated with N elementary cell by transmission medium and forms supervising the network.Transmission medium is IC-card or telephone wire and modem interface circuit.IC-card is implemented instantaneous contact separation transmission manner to the central controller of supervisory computer and N elementary cell.And telephone wire implements to fixedly connected the timesharing transmission manner with modulator-demodular unit with the central controller of supervisory computer, a N elementary cell.
The present invention is owing to the centralized control structure of having realized user's electric quantity acquisition, processing, storage, demonstration and ammeter duty are shown, thereby the user need not reading of data from this electric supply meter again, also just realized the concentrated whole closing appliance of electric supply meter and controller.So just can be convenient to manage, stop the damage of illegal electricity consumption and ammeter and controller and lose.Automaticity improves greatly, and whole data handling procedure need not manually to participate in, and accurate measurement is real-time, and unmanned is inaccurate factor.Reduce the meter reading personnel, alleviated labour intensity, improved work efficiency.System cost is low, compares cost with single deck tape-recorder formula watt-hour meter and can reduce about 30～70%.The system expandability is strong, and both supervisory computer and elementary cell can proportionally increase, to realize the large tracts of land network management.Terminal extensibility in the elementary cell is also strong.Terminal can reach 250 at most.Transmission medium also can be selected IC-card or telephone wire according to actual conditions.The system transparency height, but see own last electric weight on user's slave controller at any time, and when last electric weight during less than certain value, status indicator lamp is just alarmed to user prompt, calls the electricity charge.What electrical management personnel slave controller obtained contains much information, comprise Date of Sampling, time, the last electric weight of each user, user's excess power consumption and time of super usefulness.One table multipotency, this element also can have the function of time-sharing electricity meter.The maintainer can determine the duty of each electric supply meter by the status indicator lamp of controller, provides intuitively, safeguards easily and diagnostic information, has made things convenient for the maintainer.
