Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
A kind of intelligent portable sound wave fire extinguisher, including power supply, acoustic emission cylinder and electric control function module；Electric control function module includes MSP430 single-chip microcomputer, temperature sensor, sound wave conversion module, acoustic power amplifier, speaker and gsm wireless communication module；Power supply is arranged on the left side of acoustic emission cylinder；Electric control function module is arranged on the left of acoustic emission cylinder, and is positioned at above power supply；Temperature sensor is arranged on the lower position of acoustic emission cylinder, and is positioned at the right side of power supply；Electronic control module is connected with power supply, and temperature sensor, sound wave conversion module, gsm communication module are connected with MSP430 single-chip microcomputer respectively, and acoustic power amplifier is connected with sound wave conversion module, speaker respectively.
Concrete, including hand holding handle, fire extinguishing switch, frequency of sound wave conversion button, fire alarm switch and low-frequency sound wave outlet, hand holding handle is arranged on above electric control function module, frequency of sound wave conversion button is arranged on the left of hand holding handle, fire extinguishing switch is arranged on the right side of hand holding handle, fire alarm switch is arranged on below acoustic emission cylinder, it is positioned on the right side of power supply on the left of temperature sensor, low-frequency sound wave outlet is arranged on the right side of acoustic emission cylinder, fire extinguishing switch, frequency of sound wave conversion button, fire alarm switch is connected with electric control function module respectively, acoustic emission cylinder be provided externally with one layer of fire proofing material, the frequency of sound wave scope of acoustic power amplifier output is 30-60Hz.
When switch of putting out a fire is in open mode, master controller MSP430 single-chip microcomputer produces low frequency pulse-width modulation PWM acoustic signals, PWM acoustical range 30～60Hz, acquiescence PWM frequency of sound wave 40Hz when fire extinguisher starts, often press a frequency of sound wave conversion button master controller MSP430 single-chip microcomputer and produce low frequency PWM acoustic signals increase 5Hz, returning 30Hz after reaching 60Hz, namely sound wave conversion step-length is 5Hz, and excursion is that 30～60Hz repeats.PWM acoustic signals then through speaker and sound wave launching tube, finally exports output at the low-frequency sound wave of acoustic emission cylinder terminal after acoustic power amplifier amplifies.When switch of putting out a fire is closed, open fire alarm switch, then temperature sensor starts, fire extinguisher is in environmental monitoring state, and during due to breaking out of fire, scene temperature is higher, and temperature sensor monitors is abnormal to ambient temperature, when namely exceeding boundary value, master controller MSP430 Single-chip Controlling gsm wireless communication module sends alarming short message to user mobile phone, until receiving the confirmation note of user, otherwise resends an alarming short message at interval of 1 minute.
Pulse-width modulation PWM signal is the digital signal that one has fixed cycle (T) indefinite dutycycle (t), when producing a certain low-frequency signals, the cycle allowing sampling pulse remains unchanged, 1 dutycycle is changed within each sampling period, the rule changed presses sine table change, and output signal produces the sinusoidal sound wave signal of same frequency after sound wave conversion module.
Pulse-width modulation PWM signal is produced the frequency signal of 30～60HZ by the intervalometer Timer_A or intervalometer Timer_B of MSP430 single-chip microcomputer.
Sound wave conversion module is RC low pass filter, and circuit is connected with the intervalometer Timer_A or intervalometer Timer_B of MSP430 single-chip microcomputer, by being just transformed into corresponding sine wave signal after filtering the higher hamonic wave in pwm signal.
Acoustic power amplifier is formed power amplification circuit by ultra-low noise precision amplifier OPA27.
Temperature sensor is platinum resistance Pt100, working range is (-50～600) DEG C, circuit is connected with MSP430 single-chip microcomputer, owing to this fire extinguisher volume is little, the conductor length that temperature sensor is connected with master controller MSP430 single-chip microcomputer is shorter, the impact of the resistance on wire is negligible, so platinum resistance Pt100 adopts the method for attachment of twin wire.
Gsm wireless communication module adopts the GTM900C chip of Huawei Company, circuit is connected with MSP430 single-chip microcomputer, owing to the I/O mouth logic level of MSP430 single-chip microcomputer is 3.6V, it is more or less the same with the logic level of the I/O mouth 2.85V of GTM900C, so just can carry out hardware docking without level conversion.
This utility model volume is little, lightweight, cost is low, have portable and intelligent two-fold advantage concurrently, employing low-frequency sound wave is put out a fire, not easily felt by human ear, not resulting in noise pollution, electric control function module is provided with temperature sensor and gsm wireless communication module, and sound wave fire extinguisher is once detect that the condition of a fire immediately passes through gsm module and sends alarming short message to user mobile phone, reach monitor in real time, give warning in advance and the effect of alarm, there is very strong practicality.
Above example only in order to the technical solution of the utility model to be described, is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent replacement；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model.
