Description
Technical field
The utility model relates to a kind of instructional device of three-dimensional map model
Background technology
Seldom have in the market towards the product of middle school geography course China relief map, what have is plane map, and what have does not possess phonetic explaining and the supporting demo function of light, can't realize the multifunction teaching demand.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of Chinese relief map model that phonetic explaining and supporting light show of being furnished with.
In order to solve the problems of the technologies described above, the utility model adopts following technical proposal:
A kind of instructional device of Chinese three-dimensional map model, on the Chinese three-dimensional map model that a width of cloth launches, be provided with many switches according to diverse geographic location, main control chip connects switch, speech chip, main control chip U2, main control chip U3 are connected with main control chip respectively, speech chip is connected with power amplifier, power amplifier connects loudspeaker, and main control chip U2 is connected with the LED display lamp with main control chip U3.
Store the phonetic explaining in corresponding geographic position on the map of China model in the described speech chip in advance, control, select explanation content that should the geographic position by geographic position switch on the map of China model.
Described LED lamp is arranged on the Chinese three-dimensional map model on some geographic position: river, mountain range and Plain, the imagery of being controlled this geographic position by main control chip U2 shows.
Technique effect of the present utility model is: one, can carry out phonetic explaining automatically according to the content of user's picked at random, be furnished with corresponding light simultaneously and show two, simple in structure, with low cost.
The use explanation: the content that the user need demonstrate inputs to main control chip U1 by button, U1 gives the MP3 module according to the button numbering by sending control signal, the MP3 module finds corresponding with it voice according to control signal, and begin to play, the sound signal of MP3 output enters the voice power amplifier and amplifies the pronunciation of back promotion loudspeaker.After confirming the user key-press input, main control chip U1 is when the MP3 module is sent control signal, also simultaneously send control signal to light display chip U2, U2 gives its peripheral triode according to this control signal output control voltage, control corresponding LED etc. and light, thereby reach coupling with the phonetic explaining content.

Fig. 2 is circuit theory diagrams of the present utility model;
Fig. 3 is an audio power amplifier circuit schematic diagram of the present utility model.
Embodiment
As Fig. 1, Fig. 2 and Fig. 3, a kind of instructional device of Chinese three-dimensional map model, on the Chinese three-dimensional map model that a width of cloth launches, be provided with many switches according to diverse geographic location, main control chip connects switch, speech chip, main control chip U2, main control chip U3 are connected with main control chip respectively, speech chip is connected with power amplifier, and power amplifier connects loudspeaker, and main control chip U2 is connected with the LED display lamp with main control chip U3.
Store the phonetic explaining in corresponding geographic position on the map of China model in the described speech chip in advance, control, select explanation content that should the geographic position by geographic position switch on the map of China model.
Described LED lamp is arranged on the Chinese three-dimensional map model on some geographic position: river, mountain range and Plain, the imagery of being controlled this geographic position by main control chip U2 shows.
Specify the course of work of circuit below for example with " river "
On the panel of Chinese relief map, begin from the source 64 blue led lamps equidistantly to be installed successively according to the Changjiang river to this fragment position of estuary, the positive pole of 64 lamps is divided into 16 groups, and negative pole is divided into 4 groups, is controlled its conducting and is extinguished by chip U2, U4.
When the user presses " river " button on the lower panel, when main control chip U1 has detected the signal input, what confirm to press by key scan is the S1 key, main control chip U1 gives mp3 according to the button number by its 11st pin output control signal, the MP3 module is looked for corresponding voice document with it according to this control signal, begin to play, this sound signal is by its 20th pin output, receive the 3rd pin of audio frequency pre-amplification circuit lm386, audio frequency letter after the amplification is by its 6th pin output, by capacitor C 7 be coupled to audio power amplifier circuit U5 the input pin of U6 (TDA2030), wherein R3 R16 be volume control potentiometer, sound signal through amplifying is by its 4th pin output, promote loudspeaker LS1 and LS2 and take place, the content of phonetic explaining comprises: the Changjiang river hydrological characteristics, the regional extent of upper, middle and lower reaches and geographic entity, water development utilizes situation etc.;
At main control chip U1 when the MP3 module sends signal, the 16th of main control chip U1,17 pin send control signal simultaneously and give 16 of light display control chip U2,17 pin, after U2 receives the signal that U1 sends over, according to this signal, control its 20-27, the 32-39 pin is output low level successively, control Q1, Q3, Q5, Q7, Q9, Q11, Q13, Q15, Q17, Q19, Q21, Q23, Q25, Q27, Q29, Q31 is conducting successively, the positive pole positive electricity successively of 16 groups of coupled LED lamps, the control signal of the 1-4 pin of U2 output is simultaneously given chip U3, the first pin output low level of U3, control Q2 conducting, the LED lamp that negative pole links to each other with Q2 is lighted successively, form the flowing water effect, after 16 positive pulses send and finish for the first time, U2 sends control signal again and gives U3, make first pin output high level of U3, the crus secunda output low level, Q2 ends, the Q4 conducting, so circulation, up to the Q8 conducting, repeat above-mentioned cyclic process again, with regard to realized with the effect of running lamp demonstrated the Changjiang river from the cradle until the motion process of estuary.
