The utility model comprises a conventional magnetoelectric electrical meter and a rationing card; besides, the inner of the kilowatt-hour meter is added with a transporting power pre-setting device circuit, a metering simultaneous discrimination circuit, a code circuit and a locking circuit. When the cipher card type rationing kilowatt-hour meter is adopted, the kilowatt-hour meter is not needed to be recorded by the manpower, and the user only need to buy the rationing card. The cipher card type rationing kilowatt-hour meter has the various functions of counting, rationing, rating running out, automatic alarm and code protection. The utility model has the advantages of simple structure, high reliability and low cost. The cipher card type rationing kilowatt-hour meter is suitable for the electric power department.
Description
The utility model relates to a kind of quantitative watt-hour meter of password cassette that is used to measure electric power merit current time integration.
Metering and charge for electric degree in the power department management of power use at present follow the magnetoelectricity machinery metering of spreading, the method for manually making a copy for always.Management disperses, manually copies and accepts contradictions such as workload is big, electricity charge recovery is untimely and can not get solving.
Chinese patent CN88219725.8 discloses a kind of Computerized multifunctional electrical consuming monitor, and each uses the electric power of electric unit rationed with system controlled by computer.But the microcomputer price is higher, can only be rationed, and the electricity charge are reclaimed untimely and metering falls behind to electric degree machinery, and the workload of manually making a copy for is big.
The purpose of this utility model be to provide a kind of reliable, simple in structure, cheap, toll administration is strict, need not manually copy and accept, and has the quantitative watt-hour meter of password cassette of stored count and quantitative two kinds of functions simultaneously.
The purpose of utility model is achieved in that and adopts conventional magneto-electric watt-hour meter that add the quantitative card that is carved with the electronics sample circuit, the electric degree surface has the quantitative card patchhole.Transmission power presetter device, warning acoustical generator and illuminator are arranged in the ammeter.Be connected to prewired circuit, metering synchronousing distinguishing circuit, exclusive circuit and the sound light alarming circuit of transmission power behind the ammeter magnetic coil.
(embodiment) is further described utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model functional-block diagram.
Fig. 2 is the utility model electrical schematic diagram.
With reference to accompanying drawing, its magnetoelectricity sample circuit is with watt-hour meter is consistent at present.But at present watt-hour meter system is by directly output behind the solenoid, and the utility model then behind solenoid, inserts the transmission power prewired circuit, and is transported to electronics sample circuit on the quantitative card by Power Conversion.
Transmission power presets to be preset with the transmission power prewired circuit by transmission power to be formed.One of embodiment presets for a kind of transmission power: install a transmission gear above the stored count transmission gear in watt-hour meter additional, transmission gear drives the transmission of quantitative counting device, the quantitative counting device presets quantitative tooth of injection-compression molding on several positions, quantitatively the position of tooth and quantitative card to read in the hole site corresponding.Another kind of embodiment is for being equipped with quantitative tooth on the accumulative total device, its position is to preset number to subtract 1, quantitatively tooth be contained in position and quantitative card on the stored count device to read in the hole site corresponding.The transmission power prewired circuit is on integrated package ［ 4 ］.
Quantitative card ［ 1 ］ shape is to mould plating silicon-carbon film formation substrate on the sheet firmly, with the raceway groove that is photo-etched into the silicon-carbon film is being merotomized then, forming the electronics sample circuit that connects with transmission power circuit, exclusive circuit and cryptochannel respectively with the computer format floppy sheet.Open one on the substrate and read in the similar small square hole in hole to the computer format floppy sheet, it is corresponding that the position of small square hole and transmission power preset, and with plastic spraying thin film protective substrate.
The transmission power prewired circuit is to deliver to quantitative card from the magnetoelectricity sample circuit through after the Power Conversion, little electric current is handled after quantitative card is delivered to the transmission power prewired circuit, when reaching the current potential that quantitatively presets, the dosing hole of gear cutting simultaneously quantitatively read in the hole time, the transmission power prewired circuit just has signal to output to metering to differentiate electrical equipment synchronously.
Integrated circuit block ［ 4 ］ includes power conversion circuit, metering synchronous other circuit, switch executive circuit and the exclusive circuit before transmission power prewired circuit, the electronics sampling.The metering synchronousing distinguishing circuit only ought be imported transmission power prewired circuit signal, electronics sample circuit signal simultaneously, when the unlocking signal of exclusive circuit and cryptochannel signal, the metering synchronousing distinguishing circuit just has signal output, one the tunnel delivers to the switch executive circuit, one the tunnel delivers to delay circuit, delay time is controlled by supply department, and termination signal of output is stopped power supply to executive circuit, executive circuit starting switch when time-delay goes out eventually.Switch ［ 7 ］ is a belt switch normally closed type relay, a protection diode ［ 6 ］ in parallel.
Cryptochannel integrated package ［ 11 ］ is made up of typical coding circuit and decoding scheme, and digital signal becomes through the conversion of several moulds delivers to the metering synchronousing distinguishing circuit after simulating electric signal, and cryptochannel only just works behind switch trip.
The warning circuit integrated package comprises conventional delay circuit harmony, optical alarm circuit.
Acoustical generator is loudspeaker, and acoustical generator is a light emitting diode.
The utility model working condition is such: before quantitative card ［ 1 ］ did not insert watt-hour meter, circuit was obstructed, and watt-hour meter is not worked.After quantitative card ［ 1 ］ insertion, circuit is connected, and magnetoelectricity sample circuit and electronics sample circuit are started working, and counter begins counting, drives simultaneously quantitatively to take turns to rotate.After integration that counter meter quota is decided electric weight, electronics sample circuit reaches certain numerical value, quantitatively wheel matches with quantitative card ［ 1 ］ in addition, export a stopping pulse, export a sound and light alarm pulse simultaneously, start warning device, after time-delay, stopping pulse of control circuit output, make the relay switch tripping operation, ammeter quits work.Delay time has the sufficient time to insert new quantitative card ［ 1 ］ again under power-off condition to guarantee the user.
When new quantitative card ［ 1 ］ inserts, start cryptochannel, coding circuit is implemented the confidentiality encode management by power supply department to the user, not only can not start watt-hour meter during the error code input, and output alarm signal.When the input proper password, export enabling pulse immediately, exclusive circuit makes sound light alarming circuit and the whole lockings of delay circuit, and circuit is connected.
Adopt the utility model, the ammeter of need not manpower making a copy for, the user buys quantitative card voluntarily and uses continuously, has password to guarantee unlikely misusing.Watt-hour meter have simultaneously counting, quantitatively, quota uses up multiple functions such as automatic warning, cryptoguard.And simple in structure, adopt the only several elements of integrated circuit entire product, reliable, cheap, suitable power department large-scale popularization.
