Summary of the invention
The technical matters that the utility model solves is: bluetooth recording pen adopts single power supply, power supply powers to multiple module simultaneously, the internal resistance of source is easily caused to increase, output voltage reduces, reduce the stability of recording pen work, power-on time is short simultaneously, easily causes information transmission not smooth, or delayed work because changing battery once electricity deficiency.
The technical scheme that the utility model provides is: a kind of bluetooth recording pen, comprise bluetooth equipment and main frame, the first playback unit that described bluetooth equipment comprises the first bluetooth unit, the audio signal processing unit be connected with described first bluetooth unit and is connected with described audio signal processing unit; Described main frame comprises: for the second bluetooth unit connected with described first bluetooth unit; Be connected with described second bluetooth unit, for recording audio signal, to the sound signal recorded or the recording/playback signal processing unit needing the sound signal play to process; Be connected with described recording/playback signal processing unit and described second bluetooth unit, for preserving the sound signal of the recording that described recording/playback signal processing unit exports, or obtain the processor needing the sound signal play to export described recording/playback signal processing unit; To the power module of host supplying power; One end is connected with described processor, the bluetooth opening switch of other end ground connection, and described power module comprises the first switch element, the first battery unit, second switch unit, the second battery unit, an AD unit, the 2nd AD unit; First battery unit by the first switch element be the second bluetooth unit, described recording/playback signal processing unit and described processor power; Second battery unit by second switch unit be the second bluetooth unit, described recording/playback signal processing unit and described processor power; The input end of the one AD unit connects the output terminal of the first battery unit, the output terminal connection handling device of an AD unit; The input end of the 2nd AD unit connects the output terminal of the second battery unit, the output terminal connection handling device of the 2nd AD unit; The first described switch element, second switch unit contain control end, and processor connects the control end of the first switch element and second switch unit.
Further, the first described switch element and second switch unit are triode.This element low price, can the break-make of effective electric control power supply switch circuit.
Further, the described processor microcontroller that comprises audio codec, storage unit and be connected with described audio codec and described storage unit respectively.This processor is integrated with the basic controlling components and parts needed for recording pen, and structure is simple, with low cost.
Further, described microcontroller adopts STC89C58 single-chip microcomputer.
Be compared with the prior art, technique effect of the present utility model is: the utility model has two power supplys, once occur that power supply electricity deficiency or low voltage can change supplying cell automatically; Still have powered battery there will not be when the battery replacement is required and interrupt surveying work situation, the therefore very good machine of the fluency of acknowledge(ment) signal.
Accompanying drawing explanation
Fig. 1, structural representation of the present utility model.
Embodiment
1 further the utility model embodiment is made an explanation by reference to the accompanying drawings.
Embodiment 1 one kinds of bluetooth recording pens, comprise bluetooth equipment and main frame, the first playback unit that described bluetooth equipment comprises the first bluetooth unit, the audio signal processing unit be connected with described first bluetooth unit and is connected with described audio signal processing unit; Described main frame comprises: for the second bluetooth unit connected with described first bluetooth unit; Be connected with described second bluetooth unit, for recording audio signal, to the sound signal recorded or the recording/playback signal processing unit needing the sound signal play to process; Be connected with described recording/playback signal processing unit and described second bluetooth unit, for preserving the sound signal of the recording that described recording/playback signal processing unit exports, or obtain the processor needing the sound signal play to export described recording/playback signal processing unit; To the power module of host supplying power; One end is connected with described processor, the bluetooth opening switch of other end ground connection, and described power module comprises the first switch element, the first battery unit, second switch unit, the second battery unit, an AD unit, the 2nd AD unit; First battery unit by the first switch element be the second bluetooth unit, described recording/playback signal processing unit and described processor power; Second battery unit by second switch unit be the second bluetooth unit, described recording/playback signal processing unit and described processor power; The input end of the one AD unit connects the output terminal of the first battery unit, the output terminal connection handling device of an AD unit; The input end of the 2nd AD unit connects the output terminal of the second battery unit, the output terminal connection handling device of the 2nd AD unit; The first described switch element, second switch unit contain control end, and processor connects the control end of the first switch element and second switch unit.The first described switch element and second switch unit can take triode.This element low price, can the break-make of effective electric control power supply switch circuit.Further, the described processor microcontroller that comprises audio codec, storage unit and be connected with described audio codec and described storage unit respectively.This processor is integrated with the basic controlling components and parts needed for recording pen, and structure is simple, with low cost.Described microcontroller adopts STC89C58 single-chip microcomputer.
Principle of work of the present utility model: battery time is with after having grown, and the internal resistance of battery can become large, the quantity of electric charge reduces, and electromotive force is also in reduction simultaneously, so output voltage can reduce; An AD unit and the 2nd AD unit is adopted to detect the size of the first battery unit and the second battery unit output end voltage respectively in real time, processor according to the voltage signal size of an AD unit and the input of the 2nd AD unit, thus determine second switch unit and second switch unit which need closed which need to disconnect.It should be noted that when the first battery unit is the second bluetooth unit by the first switch element, described recording/playback signal processing unit, when processor is powered, when an AD unit inspection to the first battery cell voltage lower than processor in after pre-set numerical value, controller unit should first closed second switch unit, disconnect the first switch element again, in like manner, when the second battery unit is the second bluetooth unit by second switch unit, described recording/playback signal processing unit, when processor is powered, when the 2nd AD unit inspection to the second battery cell voltage lower than processor in after pre-set numerical value, processor first should close the first switch element, disconnect second switch unit again.First battery unit of the present utility model and the second battery unit are 6V, find that output voltage just changes battery unit automatically lower than 4.5V once detect.
