Abstract

The utility model provides a multifunctional intelligent globe, which comprises a voice recognition and playing module, a main control module, a tripod head rotating module and LED lamps. The multifunctional intelligent globe is characterized in that the main control module is respectively connected with the voice recognition and playing module, the tripod head rotating module and the LED lamp. When some user speaks the name of a country, the binary sequence of an identified result is decoded by the voice recognition and playing module and then the decoded result is processed and outputted by the main control module. The tripod head rotating module is then driven by the main control module to rotate the globe to the corresponding position of the country. Meanwhile, the tripod head rotating module is driven to lighten an LED lamp at a corresponding position and the voice recognition and playing module is controlled by the main control module to play MP3 data related to the information of the country and prestored in the voice recognition and playing module.

Description

The multifunctional intellectual terrestrial globe

Technical field

The utility model relates to a kind of terrestrial globe, especially a kind of multifunctional intellectual terrestrial globe.

Background technology

Geographical teaching be unable to do without terrestrial globe, globe can only be realized one-dimensional rotation by external force traditionally, coordinate the teacher to teach geographical knowledge, lack fresh impression on the audiences, the positive learning interest of mobilizing students to geography class, in order to improve the uninteresting of geographical teaching, strengthen its interest, need to be by advanced teaching mould in teaching process, thus motivate students' interest in learning, guarantee quality of instruction.And powerful globe intelligently can be in the aerial rotation without any support and contact electricity, as magnetic suspension tellurian is that a kind of these terrestrial globe complex structural designs of intelligent sound terrestrial globe that can utilize wireless sound production and advanced invisible code optical recognition technique to realize voice control rotation are with high costs.

Summary of the invention

In view of above reason, the utility model provides a kind of order of the acoustic control by the user to be converted into the multifunctional intellectual terrestrial globe of national geography position.

The utility model provides a kind of multifunctional intellectual terrestrial globe, comprise speech recognition playing module, main control module, cloud platform rotation module, LED lamp, it is characterized in that: main control module is connected with speech recognition playing module, cloud platform rotation module, LED lamp respectively.The national title of saying as any user, output after the speech recognition playing module has the binary sequence of the result of identification main control module to process after decoding, drive the cloud platform rotation module to be rotated the globe to the respective country position, and the drive point LED lamp that exposes and answer position, control the MP3 data that the speech recognition playing module is play pre-stored this country's relevant information simultaneously.

The beneficial effects of the utility model are, easy operating is interesting strong, can fully excite student's curiosity and aspiration to knowledge, and design letter simultaneously, single with low cost is more suitable for using each school is universal, has higher practical value.

The accompanying drawing explanation

Fig. 1 is theory diagram of the present utility model .

Embodiment

As shown in Figure 1, the utility model provides a kind of multifunctional intellectual terrestrial globe, comprise speech recognition playing module 1, main control module 2, cloud platform rotation module 3, LED lamp 4, it is characterized in that: main control module 2 is connected with speech recognition playing module 1, cloud platform rotation module 3, LED lamp 4 respectively.The national title of saying as any user, output after speech recognition playing module 1 has the binary sequence of the result of identification main control module 2 to process after decoding, drive cloud platform rotation module 3 to be rotated the globe to the respective country position, and the drive point LED lamp 4 that exposes and answer position, control the MP3 data that speech recognition playing module 1 is play pre-stored this country's relevant information simultaneously.

Speech recognition playing module 1 mainly consists of speech chip LD3320, STC10L08XE single-chip microcomputer and other peripheral circuits.Speech chip LD3320 inside solidification has complete unspecified person speech recognition features storehouse and efficient unspecified person speech recognition search engine modules, does not need precondition and recording.The pinyin string that only needs single-chip microcomputer that the candidate is identified to statement is imported chip internal into, by the DSP algorithm of chip internal, finds out the best identified result.This chip is also supported the MP3 playing function simultaneously, now needs external Flash chip, is used for storing the data such as sound material of playing.The STC10L08XE single-chip microcomputer reads the data of serial storage chip, sending into successively the LD3320 chip internal just can be from the respective pins output sound of chip, adopt parallel communication mode between STC10L08XE single-chip microcomputer and speech chip LD3320, therefore need to use 8 data lines and 4 control signals by speech chip and single-chip microcomputer parallel join on hardware.That main control module 2 adopts is AT89S52, a kind of low-power consumption manufactured and designed by Atmel company, high performance 8 single-chip microcomputers, be used for receiving as the master controller P1 mouth of globe intelligently the rotation that voice identification result is controlled The Cloud Terrace, P2 and P3 mouth are used for controlling the lighting circuit etc. that some peripheral main circuits will comprise the reset circuit lamp.Cloud platform rotation module 3 is designed with 4 ports of controlling rotation direction, be respectively that level is turned left, level is right, turn rising, descend, need the alternating current of 24V to drive, and the binary sequence of voice identification result is exported by the I/O mouth of main control module 2 after decoding, its port level is the direct current of 0-5V.In order to make main control module 2 drive cloud platform rotation according to voice identification result, place a current amplifier part ULN2003 between AT89S52 and The Cloud Terrace.ULN2003 is large electric current, high withstand voltage darlington array, comprises 7 Darlington transistors, under the operating voltage of 5V, can with cmos circuit, directly be connected with TTL, so just can directly process the data that originally need the standard logic impact damper to process.

Claims

1. a multifunctional intellectual terrestrial globe, comprise speech recognition playing module (1), main control module (2), cloud platform rotation module (3), LED lamp (4), it is characterized in that: main control module (2) is connected with speech recognition playing module (1), cloud platform rotation module (3), LED lamp (4) respectively.
