Below, the present invention will be described by example with reference to accompanying drawing.
The accompanying drawing summary
Fig. 1 roughly illustrates according to a system of the present invention.
Embodiment
Applicant's the F120050501 of patented claim early, the same fashion of submitting in the application is what maintain secrecy, discloses a kind of method, wherein the measurement result of energy meter and qualitative data use mobile phone and RFID agreement to be delivered to Utilities Electric Co..The invention provides a kind of method, wherein by utilizing a kind of local sensor network of identical technical construction, its purpose is to read automatically for example ammeter of apartment.Certainly, the RFID local network of the type of discussing also can be used for other application scenario.
Fig. 1 is illustrated in typical places such as factory, shopping center, apartment, and large quantities of there watt-hour meter 1 are installed in the watt-hour meter box 6.Therefore each watt-hour meter is measured electric energy consumption at least, but generally also can obtain about electric current, voltage, phase place between them and the information of power, as instantaneous value and mean value from these instrument.Problem is how these instrument 1 to be incorporated into economically in the field that automatic remote reads.If the GSM data link is installed in each instrument, system will become very expensive and instrument can not be installed in metallic install bin 6.If the GSM device is installed in the outside, then must use wired or wireless data network that instrument is connected in this GSM device.Based on the wireless network of radiotelegraphy is expensive and the metallic install bin can hinder the propagation of radio frequency.Wired connection can work, but system's necessary protected property ground separation, this can make cable network more be difficult to realize.Optic network is a kind of considerable solution.
In the solution of Fig. 1, adopt the RFID technology to form LAN (Local Area Network).In this method, have RFID circuit 2 in each watt-hour meter 1, or simulate its electron device, in its storer, write down measurement data.Therefore, circuit 2 comprises and is used to write down the necessary storer of measured value.Antenna 3 is connected in each RFID circuit 2.Be positioned at the electron device 2 that the outer acquisition instrument 4 of switch box not only comprises analog RF ID circuit, also comprise and read RFID circuits needed electron device 8 and antenna 3.Read electron device and be used for the measurement result of reading and recording in the RFID of energy meter 1 circuit thus.The conductor loop 5 of the data that RFID circuit 2 by energy meter 1 sends by sealing is sent to the antenna 3 of acquisition instrument 4 and is sent to by it and read electron device 8 and transmit instrument 1 and acquisition instrument 4 that the conductor loop 5 of this sealing is pressed close to be monitored to wait on suitable data network 7.
Can wherein there be the suitable telecommunication installation 10 that is used for transmitting data on data network 7 in acquisition instrument 4 only for being equipped with the RFID unit that RFID reads circuit 8.Telecommunication installation 10 can operate on the line or with wireless mode.The suitable data delivery form for example is that GPRS, GSM, WLAN, RFID and cable data transmit agreement.Yet in preferred embodiment of the present invention, acquisition instrument 4 also is an energy-consumption meter, and its measures generally the energy sum from the instrument 1 of conductor, and the total current of instrument 1 flows through described conductor.
Because the present invention, acquisition instrument 4 can use its reading device 8 to read the measurement data of all watt-hour meter 1 with very frequent interval (for example 1 second).When gauge field was installed, RFID circuit according to the present invention respectively defined an address for each instrument 1.This means that instrument 1 can any order be installed in the casing 6.After this, every apartment or other corresponding energy consumption Charging Detail Record unit can be connected in and the correct corresponding RFID address of instrument by program, and it is generally the address, apartment in the apartment.Owing in acquisition instrument 4, also have the RFID interface, therefore after installation, also can for example use the mobile phone that is equipped with the RFID reader to guarantee acquisition instrument work.The only odd word of installation phase is the conductor loop 5 of constructing closed loop around instrument 1 and 4.Fabrication phase at casing 6 just can form circuit loop 5 in new instrument box.If use 13.56-MHz RFID technology, then acquisition instrument 4 also can be installed in outside the metering house.Certainly, this requires conductor loop 5 by wall, perhaps instrument is installed on the wall, and makes conductor loop 5 appear at the opposite side of wall.
Therefore conductor loop 5 is conductor loops, for example can by any Ampereconductors is connected to form unified loop, short-circuited conducting sleeve is realized.The coating of this conductor is typically insulation.Conductor loop 5 is positioned near watt-hour meter 1 and 4, contacts but do not form electric current with them.Is 5-100mm in order to what fully be connected in instrument 1 or 4 from conductor 5 suitable distances.Suitably distance depends on the emissive power that adopted and the type and the geometric configuration of antenna in essence---except that other factors---.Fig. 1 illustrates and places conductor loop 5 more preferably to select as the present invention is a kind of instrument 1 and 4.The position of the conductor loop 5 certainly relative instrument 1 of alternate manner and 4 is provided with, as long as by keeping instrument 1 to be connected from enough little the considering with the enough signal of conductor loop 5 of the distance of conductor loop 5 with 4.
When beginning at least, it is best utilizing 13.56-MHz RFID technique construction system, if but in the future 869-MHz or 2.45-GHz RFID read electron device and become available in mobile phone, then also can be around their standard constructing system.
In this application, term " electrical equipment " refers to for example energy meter, power meter, galvanometer and voltmeter instrument and the galvanometer instrument of short-circuit and grounding circuit, the perhaps relay or the switch of power distribution network.Term " electrical equipment " for example also refers to maybe can transmit its a plurality of parts of information and receiving control information to the household electrical appliance that are equipped with the RFID circuit.
Term conductor arrangement not only refers to conductor loop shown in Figure 5, also refers to for example to be connected in the wiring of the electrical network of ammeter 1 and 4, and they for example connect in a suitable manner by perception or capacitive uses.In this case, perhaps by between RFID circuit and cable, forming enough big electric capacity in the capacitive mode, perhaps in perceptual mode, the layout from each instrument from the RFID circuit to electrical network connects by the connection that forms similar transformer between the wiring of the RFID of each instrument circuit and electrical network.
By using said process, do not need to change the connection of electrical network; But during connecting each instrument or in the instrument fabrication phase, make change by suitable perception or capacitive interface unit 11.
By suitably selecting transmission power level, the parallel gauge field (for example at adjacent apartment) that is provided with can be not interfering with each other.
