Background technology
Electric energy meter is that a kind of metering user that is used for uses the how many instrument of electric energy; it can be divided into mechanical electric energy meter and the large class of electrical type electric energy meter two; mechanical power energy meter is because often there will be the phenomenon of error; so gradually replaced by the electric energy meter of electronic type; but current electronic electric energy meter also needs manually to check meter, and is very lost labor, its operation interface is also intelligent not; for this reason, we propose a kind of intelligent electric energy meter.
Utility model content
The purpose of this utility model is to provide a kind of intelligent electric energy 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 energy meter, comprise upper cover, lower cover, electric energy chip, forceful electric power terminal, light current terminal, program button, inquire button, liquid crystal display, idle flashlight, meritorious flashlight, alarm lamp, infrared emission hole and infrared receiver hole, described electric energy chip is arranged on down and covers, and described upper cover is connected with lower cover; Next is upper in the right edge of upper cover for described program button and inquire button one, described liquid crystal display is positioned at and covers, and described idle flashlight, meritorious flashlight, alarm lamp, infrared emission hole and infrared receiver hole are positioned at the bottom of the liquid crystal display of upper cover from right to left successively; Described forceful electric power terminal and light current terminal one next upperly to cover in upper.
Preferably, described electric energy chip leaves three waterproof.
Preferably, on described, cover the cutting leaving lower cover, under cover the jack leaving upper cover.
Preferably, described program button, inquire button, liquid crystal display, idle flashlight, meritorious flashlight, alarm lamp, infrared emission hole are all connected with electric energy chip by power lead with infrared receiver hole.
Preferably, described forceful electric power terminal is connected with electric energy chip by power lead with light current terminal.
Principle of work: during electric energy meter work, voltage is through the dividing potential drop of resistance, electric current is after current transformer samples on sample resistance, send into special electric energy chip to process, and be converted into the CPU that digital signal delivers on electric energy chip and calculate, owing to have employed special electric energy process chip, electric current and voltage sampling resolution is greatly improved, and have sufficient time to measure electric energy more accurately, thus the accuracy of measuring of electric energy meter is had remarkable improvement, CPU is used for time-shared charge and the various inputoutput data of process, by the data reading of serial line interface by special electric energy chip, and complete the metering of timesharing active energy and maximum demand metering function according to the period preset, show every data as required, communication transfer is carried out by infrared emission hole and infrared receiver hole, and complete the monitoring of operational factor, record stores various data.
Compared with prior art, the beneficial effects of the utility model are: this intelligent electric energy meter, adopt electric energy chip, infrared emission hole and infrared receiver hole can realize electric energy meter and external unit carries out long-range connection, program button can change the program in electric energy chip, and operator can be operated electric energy meter by inquire button and liquid crystal display very easily.
