Description

A kind of easy sound localization module

Technical field

The present invention relates to information communication field of engineering technology, particularly a kind of easy sound localization module.

Background technology

People often judge the position of pronunciation object by the sense of hearing. Sound localization in the daily life of humans and animals significance. Such as, when you walk alone, hearing suddenly a sound. you can expect what meaning of this sound, and to you with or without threat, it is from where etc. Determine that direction and the distance of sound need to compare from two ear information, although you can do very soon than judgement and reaction, but the sound localization process complicated comprehensive function that is auditory system.

Traditional sound localization modular structure relative complex, cost is also higher, and location efficiency is lower, and travelling speed is slower.

Summary of the invention

It is an object of the invention to provide the sound localization module that a kind of cost is lower, simple and reasonable.

The technical solution used in the present invention is:

A kind of easy sound localization module, its innovative point is: main body comprises power supply module, micro-chip, sound module, acoustic reception module, information processing module and display module;

Described power supply module is successively with described micro-chip, sound module is unidirectional is connected, and described acoustic reception module is successively with described information processing module, liquid-crystal display module is unidirectional is connected.

Further, described micro-chip adopts MSP430G2553 chip.

Further, described information processing module adopts MSP430F169 chip.

Further, described sound module comprises LM567 amplifier and LM358 amplifier.

The useful effect of the present invention is as follows:

1) controller module adopts the two panels low-power consumption MSP430G2553 micro-chip of TI company as Master control chip, it is the micro-chip of 16, instruction set (RISC) structure is simplified in employing, having abundant addressing mode, succinct 27 core instructions and a large amount of simulation instructions, many features ensure that and can develop high efficiency source routine;

2) sound module adopts MSP430G2553 micro-chip, in order to produce the square wave signal of a more stable 500Hz, after triode drives, send into high-precision electronic loud speaker sounding, can obtaining the voice signal of more stable 500Hz, its circuit power consumption is very little, simple and convenient;

3) acoustic reception module adopts LM567 amplifier and LM358 amplifier composition; First the faint sound signal received is amplified by acoustic reception module by two-stage amplifier, and then is the bandpass filter filtering clutter of 500Hz by mid-frequency, obtains stable 500Hz square wave; Sound is first amplified by this module by amplifier LM358, LM567 is phaselocked loop circuit tone decoder, extensively for the tone code demodulation of various receiving end, therefore audio frequency amplification is carried out with LM567, by filter network filtering clutter, make the square wave signal received more stable, and the resource making this module needs is few, price is cheap;

4) sound module is located by information processing module according to the transfer voice time difference received. The time that the sound that sound module sends passes to different receptor is different, counts according to the different reception time, does difference, it can be determined that go out the alternate position spike of sound module distance alternative sounds receiver module, so that it is determined that go out the particular location coordinate of sound module.

Embodiment

A kind of easy sound localization module as shown in Figure 1, main body comprises power supply module, micro-chip, sound module, acoustic reception module, information processing module, display module, and unidirectional is successively connected.

Schematic circuit diagram as described in Figure 2, the voltage needed due to each module in system is different, powers for realizing monocell, is accomplished in 7812,7805 and LM317 adjustable voltage on a plank, it is achieved that 12V, 5V, adjustable voltage three road voltage output function.

Sound module circuit diagram as described in Figure 3, first sound module by micro-chip timer, exports the square wave signal of a more stable 500Hz at I/O, after the amplification of triode, sends into high-precision electronic loud speaker sounding.

Acoustic reception module circuit diagram as described in Figure 4, is received by eletrect microphone, and faint sound signal is formed the square wave of 500Hz after the filtering circuit filtering that LM358 two-stage is amplified and LM567 forms.

Main program flow chart as described in Figure 5, from after, station-keeping mode can be divided into static fixing pattern and consecutive tracking pattern, then all passes through to receive 3 tunnel sound signals, then calculates X, Y-axis by the time difference, finally demonstrate coordinate.

The present invention adopts two panels low-power consumption MSP micro-chip as controller, control the co-ordination of whole sound positioning system, utilizing the I/O mouth of MSP430G2553 to export base wave frequency is 500Hz, time length is the voice signal of 1s, then through acoustic reception module, the signal received is delivered to MSP430F169 information processing resume module. One flat plate is puted up the graph paper of a 500*350mm, divide by a fixed installation acoustic reception module outside its corner, sound signal is detected by eletrect microphone, the voice signal that frequency is about 500Hz is sent to information processing module by wire by acoustic reception module, this sound localization module is poor to the sound time of each acoustic reception module by airborne transmission according to sound module, judge X, the Y-coordinate of the position at sound module place, and on liquid crystal, show X, Y-coordinate value in digital form.
