Embodiment
With the following Examples the utility model is further described.
Intelligent electric meter datacast device, comprises box body 2, and as shown in Figure 3, be provided with control circuit in described box body 2, described control circuit comprises processing module, keyboard input module, display translation module, voice broadcast module and carrier communication module.
Described carrier communication module connects the power cable of household internal, is communicated by power cable as transmission medium with intelligent electric meter, and transmits corresponding electricity consumption data-signal to described processing module.
Described carrier communication module comprises and connects rectification reducing transformer, voltage stabilizer, coupling filter and modulator-demodular unit successively, described rectification reducing transformer connects described power cable, power cable communicates with intelligent electric meter as transmission medium, make user can be connected to intelligent electric meter whenever and wherever possible at home, and do not need to carry out wireless or wired connection near ability intelligent electric meter, be very easy to the real-time monitoring of handicapped personage for electricity consumption situation in family.Described rectification reducing transformer comprises transformer and rectification circuit, the 220V alternating current that power cable transmits by described transformer is reduced to the alternating current of 18V ~ 20V, by rectification circuit, 18V ~ 20V alternating current is converted to 18V ~ 20V direct current, is delivered to voltage stabilizer and carries out voltage stabilizing.Direct current is delivered to described coupling filter and carries out photoelectric coupling isolation after voltage stabilizing, the signal of stable DC electrical transmission.Finally, the signal of modulator-demodular unit to DC power transmission is analyzed and decodes, and the signal of DC power transmission is translated as the readable digital signal of processing module, makes processing module correctly can read digital signal, obtains relevant electricity consumption data.
Also power module is included in described carrier communication module, 220V alternating current is down to 15V alternating current by transformer by described power module, then through rectification circuit, 15V alternating current is converted to 15V direct current, 15V direct current passes through circuit of three-terminal voltage-stabilizing integrated voltage stabilizing to 5V, for described processing module.In the present embodiment, described circuit of three-terminal voltage-stabilizing integrated is LM7805.
Described processing module has various modes, the use crowd that different patterns is corresponding different.Described pattern comprises Chinese speech and reports pattern and minority language voice broadcast pattern, can also comprise other patterns.User sets corresponding pattern according to the needs of self, and electricity consumption data-signal carrier communication module collected processes, and transfers to described display translation module and/or voice broadcast module respectively.Described processing module can select the process chip of STM8 series.
Processing module described in described display translation model calling, exports the electricity consumption data that described processing module process draws to external unit.As depicted in figs. 1 and 2, in the present embodiment, described external unit is the screen 1 selecting normal monochrome LED.Described screen 1 connects described box body 2 separably.In addition, described box body 2 is connected with separable Independent keys 3, and described Independent keys 3 connects described keyboard input module.Described keyboard input module connects described processing module, and user, by described keyboard input module input instruction, sets the pattern of described processing module.User can need to determine whether use screen 1 or Independent keys 3 according to self.If when user needs the pattern setting described processing module, Independent keys 3 can be connected described box body 2, facilitate input command.If needs intuitively show from screen 1 while user needs voice broadcast, then described screen 1 can be connected box body 2.If user's set model and only need to carry out voice broadcast, then can dismantle Independent keys 3 and screen 1, thus reduce the weight of broadcast device simultaneously, be easy to carry, be user-friendly to.
Described voice broadcast module comprises the A/D converter, filter amplifier and the loudspeaker that connect successively, and the electricity consumption data in processing module, after A/D converter conversion, transfer to filter amplifier and make filter amplifying processing, play back finally by loudspeaker.Described voice broadcast module memory contains Chinese and at least two kinds of minority languages, and can switch between Chinese and at least two kinds of minority languages.If user sets Chinese speech and reports pattern, described processing module sends a command to described voice broadcast module, and voice broadcast module plays Chinese.Such as, if user sets a kind of minority language pattern, Uygur nationality's language, described voice broadcast module plays Uighur.
In concrete enforcement, described box body 2 is at least provided with one and plays button, the surface of described broadcasting button is provided with the braille of expression " broadcasting ", facilitates blind person to use.Described broadcasting button is provided with hardware Anti-shaking circuit.
Concrete operations of the present invention: connect power cable, in the present embodiment, user described broadcast device being inserted in any supply socket in a certain regional extent, can correctly read the power information of this range areas.
The pattern of described broadcast device default setting is that Chinese speech reports pattern, if user does not change the setting of pattern, directly press broadcasting button, now voice broadcast module can be play with Chinese " current balance is XX unit " and " this month consumption electricity is XX degree ", shows same information on the screen 1 simultaneously.
If user is ethnic group, need the setting of advanced row mode, the pattern of setting has two kinds of modes: a kind of is select corresponding language by Independent keys 3; Another kind is long by more than broadcasting button 5 second, user can hear prompt tone: " select Chinese please loose one's grip (Chinese broadcasting), select Uygur nationality's language please loose one's grip (dimension language is play) ... ", this prompt tone meeting loop play, until user stops after loosing one's grip.Now, described broadcast device can remember the pattern that this user selects, and adopts these languages to play when playing electricity consumption data later.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of the invention technical scheme.
