The utility model content
At can't realize sending a telegram here after the outage defective of continued broadcasting function of MP3 playback equipment in the prior art, the purpose of this utility model provides the integrated audio playing apparatus of a kind of digital intelligent.
According to an aspect of the present utility model, the integrated audio playing apparatus of a kind of digital intelligent, constitute by the integrated automatic player of MP3, it is characterized in that: the integrated automatic player of described MP3 is by the MP3 player, SD card and timing circuit, the wireless receipts of a GPRS/module, power supply and necessary external circuit constitute, described MP3 player, SD card and timing circuit, the wireless receipts of a GPRS/module, power supply and necessary external circuit are built in the cabinet, described MP3 player is by the MP3 decoding chip, NAND FLASH, power supply and other necessary peripheral circuits constitute, described MP3 player is connected with stereo set by signal wire, described timing circuit is connected with described stereo set, the wireless receipts of described GPRS/send out module to be connected with described MP3 player and main control chip.
The utility model is by realizing down Monitor Unit in the voice playing process, voice playing is suspended when making player realize outage, finishes continuity and play after restoring electricity.Be characterized in the place of installation environment power supply less stable having outage continued broadcasting function.This digital intelligent integral audio playing apparatus can provide special-purpose applied environment for the client.
Description of drawings
By reading the detailed description of non-limiting example being done with reference to the following drawings, it is more obvious that other features, objects and advantages of the present utility model will become:
Fig. 1 is the enforcement synoptic diagram of the integrated audio playing apparatus of digital intelligent;
Fig. 2 is the detection of power loss synoptic diagram of the integrated audio playing apparatus of digital intelligent; And
Fig. 3 is the circuit control module structural drawing of the integrated audio playing apparatus of digital intelligent.
Embodiment
As shown in Figure 1, the integrated audio playing apparatus of digital intelligent is made of playing controller, SD storage card, timer, loudspeaker, wireless receiving and dispatching and power supply, wherein, and described wireless receipts/send out module to preferably include the wireless receipts of a GPRS/module.Particularly, described playing controller is connected with described SD storage card, timer, loudspeaker, wireless receiving and dispatching, power supply and source of sound processor system respectively, and further, described equipment is built in the casing.Fig. 2 is the enforcement synoptic diagram of the integrated audio playing apparatus of digital intelligent about detection of power loss.The described LCD device of Fig. 3 is made of LCD screen and liquid crystal display control circuit board.Main control MCU is by the SH69P56 master control, and inside carries liquid crystal drive and real time clock circuit constitutes.The MP3 controller is made of M05-MP3 development board and SD card.Timing circuit is by timer control routine and control circuit.Preferably, power supply is made of detection of power loss and rechargeable battery and Switching Power Supply, wherein, described power loss detection means is used for realizing detection of power loss in the voice playing process, voice playing is suspended when making the integrated audio playing apparatus of described digital intelligent realize outage, finishes continuity and play after restoring electricity.Wireless receiving module cooperates the GRRS/CDMA/WIFI communication module to constitute by ARM9 platform single-chip Embedded System Design.System software is made of main control module, playing module, time block, card reading module, power supply detection module, keyboard processing module, wireless messages receiver module etc.Particularly, described main control MCU changes in the example at one respectively, and any in two-channel power amplifier and loudspeaker, keyboard and the LCD device or a multiple arrangement can be omitted.
In a variation example embodiment illustrated in fig. 1, described power loss detection means can be and described power supply control module independently mutually, correspondingly, the described power loss detection means that comprises in the described power supply can be omitted, particularly, in this variation example, described power loss detection means places in the said machine casing, and it is connected with described playing controller.
With reference to above-mentioned Fig. 2 and Fig. 3, those skilled in the art understand, described power loss detection means writes down the concrete play position of described MP3 controller when power down, and the play position that is recorded during from the last time power down after incoming call once more continues to play, thereby realizes the continued broadcasting function of cutting off the power supply.Particularly, described power loss detection means can be provided with one and break mark in described SD storage card, and breaks mark continuation broadcast from this when sending a telegram here once more; Particularly, described power loss detection means also can be set one and break record identification in other internal memories, for example identify the audio position when breaking, and realizes continuing to play thereby break record identification determine the to continue audio position broadcast according to this when sending a telegram here once more.Those skilled in the art can realize such power loss detection means in conjunction with prior art, do not repeat them here.
Equipment characteristic is in the place of installation environment power supply less stable, has outage continued broadcasting function.Common parts such as this digital intelligent integral audio playing apparatus can be placed in the building elevator, lift lobby, public corridor, public sanitary place, parking place.Public information, background music, service guide, advertising information or the like are play in the rolling of continuous controllable.Can provide special-purpose applied environment for the client.
More than specific embodiment of the utility model is described.It will be appreciated that the utility model is not limited to above-mentioned specific implementations, those skilled in the art can make various distortion or modification within the scope of the claims, and this does not influence flesh and blood of the present utility model.
