Description
Technical field
The utility model relates to electric-power metering management domain, particularly relates to a kind of Internet of Things intelligent electric meter.
Background technology
Current, the meterage management of China's electricity, that main flow adopts or manual metering mode and IC-card charging way.The manual metering i.e. person of checking meter regularly rushes towards residential block, checks meter one by one, add up and clear out cost components user; IC-card charging, needs user to supplement with money for electricity card to the appointment point of purchase or networking bank, then goes home the remaining sum in each card to brush respectively in ammeter, could continue normal use, if remaining sum is finished and does not supplement with money in time in each table, then can stop supply electricity.The efficiency of these two kinds of meter reading methods is not high, concerning user and fee collection personnel, not only time-consuming but also require great effort, and not only needs to go hither and thither, also there is serious potential safety hazard; For administrative authority, the grasp firsthand data that can not be real-time, is difficult to the statistical study of the science of carrying out, is unfavorable for scientific dispatch to the energy consumption condition of user, and error is large, poor in timeliness, statistical computation workload are large, and with artificial randomness.
Utility model content
The utility model provides a kind of Internet of Things intelligent electric meter, solves the technical matters that meter reading method efficiency of the prior art is not high, waste time and energy.
The purpose of this utility model is achieved through the following technical solutions:
A kind of Internet of Things intelligent electric meter, comprise microprocessor 1, rectifier 2, Ethernet chip 3, wave filter 4, FLASH memory 5, photoelectrical coupler 6 and module for metering electric quantity 7, wherein, described microprocessor 1 is connected with described Ethernet chip 3, described wave filter 4, described FLASH memory 5 and described module for metering electric quantity 7 respectively, described photoelectrical coupler 6 is connected with described microprocessor 1 by described wave filter 4, and described rectifier 2 is connected with described microprocessor 1, described Ethernet chip 3 and described module for metering electric quantity 7.
Technique effect of the present utility model is: achieve remote meter-reading function, and metering accurately in time, decreases artificial input.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in further detail the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, for a kind of Internet of Things intelligent electric meter that the utility model provides, comprise microprocessor 1, rectifier 2, Ethernet chip 3, wave filter 4, FLASH memory 5, photoelectrical coupler 6 and module for metering electric quantity 7, wherein, described microprocessor 1 respectively with described Ethernet chip 3, described wave filter 4, described FLASH memory 5 is connected with described module for metering electric quantity 7, described photoelectrical coupler 6 is connected with described microprocessor 1 by described wave filter 4, described rectifier 2 and described microprocessor 1, described Ethernet chip 3 is connected with described module for metering electric quantity 7.
Ethernet chip 3 coordinate microprocessor 1 realize the modulation /demodulation of electric-power wire communication signal, the modulus/digital to analog conversion of line of electric force modulation signal, output signal drive amplification, Received signal strength by wave filter 4 bandpass filtering and low noise amplification, the electric-power wire communication signal after demodulation is converted to ethernet communication signal or is electric-power wire communication signal ethernet communication signal madulation.
Ethernet chip 3 mainly processes the data of ethernet physical layer, carry out the data conversion between Physical layer and MAC layer, thus the network message realized between central processing unit 1 transmits; Major function has connection detection, auto-negotiation, speed, complete/half-duplex setting, CRC to detect, and cooperation central processing unit 1 realizes the conversion between Ethernet data-signal and power line signal.
Wherein, in order to support checking meter of ordinary electric meter simultaneously, the utility model also comprises RS485 communication module 8, and described RS485 communication module 8 is connected with described microprocessor 1.Like this, only need installation Internet of Things intelligent electric meter, gather multiple user's electricity by RS485 communication module, and concentrate electric quantity data is sent to long-range receiving end by Ethernet.
The utility model also comprises relay 9, and described relay 9 is connected with described microprocessor 1.Microprocessor 1 can carry out switching operation to user power utilization by relay 9, when receiving the instruction that remote control center is sent by Ethernet, can carry out corresponding operating to relay 9.
The utility model achieves remote meter-reading function, and metering accurately in time, decreases artificial input.
Be understandable that, the system architecture shown in figure does not form the restriction to system, can comprise the equipment more more or less than diagram, or combine some equipment, or different deployed with devices.
Above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
