Abstract
The invention relates to an energy-saving electronic watt-hour meter which comprises a display screen, wherein the display screen is connected with a display driving module of the watt-hour meter, and the display screen is connected with a display screen power. The watt-hour meter is characterized in that a power control switch is connected between the display screen and the display screen power, and the power control switch controls the power supply of the display screen part. Ordinarily, the display screen is set to be in an off state, and the display screen can be turned on through the switch when the display screen needs to be watched. The energy-saving method only aims at the processing of the display of the watt-hour meter, thereby being easy in technical realization. The display (especially the LED display) is off all the day, the display can be activated in a correlative trigger mode (such as key pressing, communication awakening and the like) when the displayed information content needs to be watched, and the display continues to be off after the completion of watching.
Description
Technical field
The present invention relates to a kind of electronic electric energy meter, relate in particular to a kind of energy-saving electronic watt-hour meter that is provided with electric energy meter display screen switch.
Background technology
All electric energy meter (single-phase, three-phase) man-machine interface displays have three kinds at present: the commentaries on classics of mechanical type wheel, LED charactron, LCD LCD.Wherein moreover mechanical type wheel commentaries on classics display should tradition not show soon superseded in this patent discussion scope; The LCD LCD is low in energy consumption, display effect is pretty good but be subjected to weather temperature effect bigger, tends to cause the LCD liquid crystal display to bring unnecessary trouble for unusually user, power department at the most of area of northern China cold low temperature in winter; The LED charactron shows that anti-weather ability is good, display effect is good, but the power consumption of itself is bigger.
According to present relevant criterion, electric energy meter must have display, though what the power consumption of much electricity table own had been done now is very low, but display apparatus module has just accounted for the very big proportion (mainly being the LED display module) of this power consumption, and electric energy meter is one in huge numbers of families one family, and it is exactly a huge power consumption that integral body counts that.If a LED charactron display shows average power consumption (because all charactron positions not necessarily show entirely) 0.05W, one family will consume 24 * 0.05 * 0.001=0.0012kWh electric energy in one day in vain so.1 year is exactly 0.0012 * 365=0.438kWh electric energy so. and 1 year national 0.438 * 300,000,000=1.314 hundred million kWd electric energy that just consumed in vain so calculates by 300,000,000 families in China.And actual this power consumption is higher than these data far away.
At the reality of this embarrassment, do not offer some clarification on hard and fast rule on the standard of the power department promulgation in department of State Grid, relevant province with regard to this piece of display yet.And below do man of Watch Factory and can not run counter to relevant criterion, the operation of economize on electricity more voluntarily.
Summary of the invention
The present invention is directed to above-mentioned problems and correct, make that product structure is simple, reduce electric energy meter power consumption, electric power energy-saving.
Concrete technical scheme is:
A kind of energy-saving electronic watt-hour meter, it comprises display screen, described display screen is connected with the driver module of electric energy meter, described display screen is connected with the display screen power supply, it is characterized in that: be connected with power control switch between described display screen and the described display screen power supply, described power control switch is the power supply of control display screen part.Display screen is set to closed condition at ordinary times, by switch display screen is opened when needs are seen display screen.
Described power control switch is a button, and described button is arranged on the panel of described electronic electric energy meter.
Described power control switch is the software trigger switch, and described software trigger switch Long-distance Control triggers.Described power control switch is to realize display screen dump and connection partly by software instruction.
Described display screen is a LED display.
This power-economizing method is only at the processing of electric energy meter display, so be easy on technology realizes.Be round-the-clock the closing of display (especially light-emitting diode display), when needs are checked the display message content, activate demonstration (waking up etc.) such as button, communication by the associated trigger mode.Check and continue to close demonstration after finishing.
Reduce power consumption, the many electric energy of saving of electric energy meter greatly, but do not influenced the serviceability of electric energy meter itself.
It is as follows that this electric energy meter power-economizing method is specifically implemented mechanism:
1, the electric energy meter display screen is wanted round-the-clock closing, and just opens demonstration when needs are checked display message, checks and continues to finish after finishing.
2, guarantee that electric energy meter can operate as normal under the situation of round-the-clock pass screen.
3, display screen must can be opened in real time in the time of need checking.
Description of drawings
Fig. 1 is the structured flowchart of the embodiment of the invention.
Embodiment
Describe the present invention by the following examples, should be noted that, cited embodiment should not understand the restriction to invention.
As shown in Figure 1: a kind of energy-saving electronic watt-hour meter of present embodiment, it comprises display screen, display screen is connected with the driver module of electric energy meter, described driver module has electric quantity data dynamic scan device, described electric quantity data dynamic scan device is connected with power control switch, display screen is set to closed condition at ordinary times, by switch display screen is opened when needs are seen display screen.
When electronic electric energy meter adopts the LED charactron to show, generally all be to be 6,5 integer-bit and 1 decimal place.Software adopts dynamic scan mode to show electric quantity data, just constantly remove to refresh video data in the regular hour, this time can regularly interrupt realizing by timer, 4ms regularly interrupts such as timing, every 4ms carries out once and interrupts, according to the zone bit execution refurbishing procedure that interrupts putting refurbishing procedure.Close the power supply that can close this display screen when screen shows, this moment, the LED screen did not just show.When showing if desired, open this power supply by button and get final product.
Obviously, foregoing is just in order to illustrate characteristics of the present invention, and is not limitation of the present invention, and the variation that the those of ordinary skill in relevant technologies field is made in the corresponding techniques field according to the present invention should belong to protection category of the present invention.
