Ammeter functionally there is also shortcomings, and its function is the most single and does not has power-off protection function, if there is power-off, then
In the chips such as RAM and CPU in machine, the data in depositor can all be lost, and therefore haves much room for improvement.
Utility model content
The purpose of this utility model is to provide a kind of single-phase intelligent ammeter metering circuit, to solve in above-mentioned background technology
The problem proposed.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of single-phase intelligent ammeter metering circuit, including sample circuit, computation chip, single-chip microcomputer, input module, wireless
Emitter, clock chip, communication interface, display lamp, display screen, power supply and memorizer, described sample circuit gathers power circuit and enters
Data in line IN are also transmitted in computation chip, and computation chip is sent into after data being processed and connect in single-chip microcomputer, single
Sheet machine is also respectively connected with input module, wireless transmitter, clock chip, communication interface, display lamp, display screen, power supply and storage
Device.
As preferred version of the present utility model: described power supply is civil power and the dual power supply system of accumulator composition.
As preferred version of the present utility model: described communication interface includes USB interface and RS485 interface.
As preferred version of the present utility model: described input module is matrix keyboard.
As preferred version of the present utility model: described single-chip microcomputer is AT89 series monolithic.
As preferred version of the present utility model: the model of described computation chip is ADE7755.
As preferred version of the present utility model: described sample circuit includes voltage sample and current sample.
Compared with prior art, the beneficial effects of the utility model are: this utility model single-phase intelligent ammeter metering circuit
Simple in construction, adds dual power supply module on the basis of tradition electric energy meter, prevents single power supply power-off from causing metering
Inaccurate, utilize single-chip microcomputer, electric energy computation chip to combine simultaneously, electric energy is carried out Real-time Collection and statistics, passes through wireless parties
Formula is transmitted, and improves intelligence degree, effectively reduces the work load of power worker.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of single-phase intelligent ammeter metering circuit.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, a kind of single-phase intelligent ammeter metering circuit, including sample circuit, computation chip, single-chip microcomputer, input
Module, wireless transmitter, clock chip, communication interface, display lamp, display screen, power supply and memorizer, described sample circuit collection
Data in power circuit inlet wire IN are also transmitted in computation chip, and computation chip sends into order after data being processed
In sheet machine, single-chip microcomputer is also respectively connected with input module, wireless transmitter, clock chip, communication interface, display lamp, display screen, electricity
Source and memorizer.
Power supply is civil power and the dual power supply system of accumulator composition.Power supply is civil power and the dual power supply of accumulator composition
Electric power system.Input module is matrix keyboard.Single-chip microcomputer is AT89 series monolithic.The model of computation chip is ADE7755.Adopt
Sample circuit includes voltage sample and current sample.
Operation principle of the present utility model is: sample circuit includes voltage sample and current sample, gathers electric lines of force respectively
Voltage data in road and current data, and be sent in ADE7755 computation chip, the computation chip merit by himself
Data can carry out metering process, and the data after processing are transferred in single-chip microcomputer, single-chip microcomputer is by its internal decoding/translate
Code device converts input signals into machine language, is shown intuitively by display screen, and the wireless transmitter in system is permissible
Data within remote transmission single-chip microcomputer, thus reduce the workload that manual metering brings, simultaneity factor is also provided with USB and connects
Mouthful and RS485 interface, can in-plant download internal data, be compared to the mode being wirelessly transferred, use interface transmission
Faster, system also uses dual power supply module to speed, prevents single power supply power-off from causing the inaccurate of metering, and input module is used
In manually arranging the time, checking the input that data etc. instruct, display lamp is the normal relay indicating light of ammeter.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
Type.Therefore, no matter from the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, this practicality is new
The scope of type is limited by claims rather than described above, it is intended that by the containing of equivalency in claim that fall
