Description
Technical field
The utility model relates to a kind of electroplating machine circuit, specifically a kind of intelligent electric meter.
Background technology
Electric energy meter is the Application of Power Metering Instruments that every household all possesses, traditional electric energy meter can only be simple metering power consumption, therefore in our life at ordinary times, the mechanical power energy meter originally extensively existed is replaced by electronic electric energy meter gradually, reason is attributed to the former stability, degree of accuracy, sensitivity, linear dynamic, the part such as power consumption all can not show a candle to the latter, but functionally also there is shortcomings in existing ammeter, such as anti-theft capability is poor, anyone can check the information of ammeter, even ammeter is stolen, intelligent electric meter major part uses single-chip microcomputer as information processing component, but general single-chip microcomputer does not have power-off protection function, if generation power-off, data in the chips such as RAM and CPU then in machine in register can all be lost, therefore have much room for improvement.
Utility model content
The purpose of this utility model is to provide a kind of intelligent electric meter, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of intelligent electric meter, comprise protection circuit, power module, host scm, from single-chip microcomputer, alarm module, Electro-metering module, sound identification module, acoustic pickup, display screen, button and GPRS module; It is characterized in that; describedly connect protection circuit, alarm module, Electro-metering module and host scm respectively from single-chip microcomputer; described host scm also connects sound identification module, MiniSD card, display screen, button and GPRS module respectively; described GPRS module also connects power supply management department and user's mobile phone respectively, and sound identification module also connects acoustic pickup.
As preferred version of the present utility model: described host scm and the model from single-chip microcomputer are STC12C5A60S2.
As preferred version of the present utility model: the core component of described Electro-metering device is AD7755 computation chip.
As preferred version of the present utility model: described GPRS module connects user's mobile phone and management of power use department by 3G wireless network.
As preferred version of the present utility model: described alarm module is the sound and light alarm of light emitting diode and loudspeaker composition.
Compared with prior art, the beneficial effects of the utility model are: the utility model intelligent electric meter adds speech identifying function on the basis of original intelligent electric meter, prevent the stolen of user power utilization information, and there is the function of remote transmission information, great simplification is checked meter operation, simultaneously circuit uses continual power supply to power for main control singlechip, prevents the single-chip microcomputer caused because having a power failure from damaging, and therefore circuit has diverse in function, the advantage that easy to use, the life-span is long.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of intelligent electric meter;
Fig. 2 is the circuit diagram of power circuit.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, a kind of intelligent electric meter, comprise protection circuit, power module, host scm, from single-chip microcomputer, alarm module, Electro-metering module, sound identification module, acoustic pickup, display screen, button and GPRS module; It is characterized in that; describedly connect protection circuit, alarm module, Electro-metering module and host scm respectively from single-chip microcomputer; described host scm also connects sound identification module, MiniSD card, display screen, button and GPRS module respectively; described GPRS module also connects power supply management department and user's mobile phone respectively, and sound identification module also connects acoustic pickup.
Described host scm and be STC12C5A60S2 from the model of single-chip microcomputer.
The core component of described Electro-metering device is AD7755 computation chip.
Described GPRS module connects user's mobile phone and management of power use department by 3G wireless network.
Described alarm module is the sound and light alarm of light emitting diode and loudspeaker composition.
Principle of work of the present utility model is: from single-chip microcomputer for gathering multi-user's information about power, overcurrent protection, the functions such as burglar alarm, and data message is reached host scm, host scm carries out the process to data, storage, data after process can display screen be checked, user needs to carry out speech recognition before use, gathered by the acoustic information of acoustic pickup by user, and undertaken determining whether former user by sound identification module, if identify successfully, then user can by checking the time by building on liquid crystal, current electric quantity, current power, the of that month electricity charge, peak at times, flat, paddy electricity charge unit price, and the information of ammeter is arranged or deletion action.Host scm is by electricity monthly, on the information store M iniSD cards such as the electricity charge, facilitate the inquiry of later stage user, if speech recognition failure, then abnormal information can be transferred to the mobile phone of user by host scm by GPRS module, send sound and light alarm from single-chip microcomputer simultaneously, prevent ammeter information stolen, when appearance electric leakage, stealing situation and when causing power consumption to increase, can will there is the situation of data exception change in single-chip microcomputer, user's mobile phone and management of power use department is transferred to by GPRS module, prompting has abnormal conditions information, be convenient to staff process in time, prepare in advance, the loss that out-of-the-way gesture is unnecessary, this ammeter is in order to prevent single-chip microcomputer in use because of the damage caused that has a power failure, power module is as shown in Figure 2 used to power, resistance R1 in figure and potentiometer RP1 is for detecting the lower limit of battery tension, R2 and RP2 is used for upper limit of detection value.When cell voltage is lower than lower limit, 555 set, the discharge tube cut-off of IC1 inside, now, diode D2 no current flows through.R4 is the biasing resistor of triode V1, and triode V1 is full closes conducting, then the voltage of power supply VCC is charged to accumulator E by resistance R4 and triode V1.When accumulator E voltage rise is to the higher limit set, when namely 6 pin current potentials of chip IC 1 are higher than its threshold level, chip IC 1 resets, and the discharge tube of IC1 inside is in conducting state, and triode V1 ends.Charging stops.When accidental power failure, when 3 pin voltages of chip IC 2 drop to about 4.8V by+5V.Diode D2 conducting, accumulator E, by D2, powers to single-chip microcomputer, ensures that power supply is uninterrupted.
