Abstract
The invention discloses a museum electronic interpreter. The museum electronic interpreter comprises a microprocessor module, and an audio storage circuit module and a power circuit module which are connected with the microprocessor module; the input end of the microprocessor module is provided with a human detection sensor; an amplifier circuit, a filter circuit and an analog to digital (A/D) switching circuit which are connected in sequence are connected between the microprocessor module and the human detection sensor; the human detection sensor is connected with the amplifier circuit; the output end of the microprocessor module is connected with an audio playing circuit module; the audio playing circuit module is connected with a power amplifier circuit module; and the power amplifier circuit module is connected with a loudspeaker. The museum electronic interpreter is simple in structure, reasonable in design, convenient to use, high in working reliability, high in practicability, and excellent in use effect.
Description
Technical field
The invention belongs to explanation equipment technical field, especially relate to a kind of museum electronics narrator.
Background technology
Along with the progress of society, increasing museum to open for free visit to citizen, but the museum opened for free generally all does not have narrator, and most of visitor also wishes to understand some historical background stories relevant to historical relic at the historical relic visited simultaneously.
Summary of the invention
Technical matters to be solved by this invention is for above-mentioned deficiency of the prior art, provides a kind of museum electronics narrator, and its structure is simple, and reasonable in design, easy to use, functional reliability is high, practical, and result of use is good.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of museum electronics narrator, it is characterized in that: comprise microprocessor module, the audio frequency storage circuit module connected with microprocessor module and the power circuit block for each module for power supply, the input end of described microprocessor module is connected to and is arranged on historical relic both sides and human body detection sensor for whether having people close before detecting historical relic, be connected with for amplifying between described microprocessor module and human body detection sensor, the signal conditioning circuit of filtering and A/D switching signal, described signal conditioning circuit is by the amplifying circuit connected successively, filtering circuit and A/D change-over circuit are formed, described human body detection sensor connects with described amplifying circuit, the output terminal of described microprocessor module is connected to voice playing circuit module, described voice playing circuit module connects with power amplification circuit module, described power amplification circuit module connects with the loudspeaker being arranged on historical relic both sides.
The present invention compared with prior art has the following advantages:
1, structure of the present invention is simple, and reasonable in design, functional reliability is high, practical, and result of use is good.
2, after the present invention installs, automatically can play voice and introduce historical relic and relevant historical background story, meet the demand of visitor.
3, long service life of the present invention, without the need to frequent maintenance maintenance.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.

Embodiment
As shown in Figure 1, the present invention includes microprocessor module 1, the audio frequency storage circuit module 3 connected with microprocessor module 1 and the power circuit block 2 for each module for power supply, the input end of described microprocessor module 1 is connected to and is arranged on historical relic both sides and human body detection sensor 4 for whether having people close before detecting historical relic, be connected with for amplifying between described microprocessor module 1 and human body detection sensor 4, the signal conditioning circuit of filtering and A/D switching signal, described signal conditioning circuit is by the amplifying circuit 5 connected successively, filtering circuit 6 and A/D change-over circuit 7 are formed, described human body detection sensor 4 connects with described amplifying circuit 5, the output terminal of described microprocessor module 1 is connected to voice playing circuit module 8, described voice playing circuit module 8 connects with power amplification circuit module 9, described power amplification circuit module 9 connects with the loudspeaker 10 being arranged on historical relic both sides.
The course of work of the present invention is: when there being people near historical relic, human body detection sensor 4 detects the signal that people is close and detected signal is exported to signal conditioning circuit, amplifying circuit 5 in signal conditioning circuit, filtering circuit 6 and A/D change-over circuit 7 amplify signal successively, micro controller module 4 is exported to after filtering and A/D conversion process, microprocessor module 4 pairs of signals carry out analyzing and processing and have judged that people is close, microprocessor module 4 reads the voice messaging being stored in audio frequency storage circuit module 3, and the historical relic prestored and relevant historical backstory are play by loudspeaker 10 by voice playing circuit module 8 and power amplification circuit module 9, after loudspeaker 10 is play and terminated, when human body detection sensor 4 detects that people leaves or unmanned when historical relic, loudspeaker 10 is in closed condition.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every above embodiment is done according to the technology of the present invention essence any simple modification, change and equivalent structure change, all still belong in the protection domain of technical solution of the present invention.
