(2) ultrasonic signal and laser guidance are combined, time remote, fireman relies on ultrasound wave to find Way out, relies on laser beam to confirm outlet time closely, ensures that fireman can the finding an exit of fast and reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of this sonar guiding escape emitter;
Fig. 2 is the connection diagram of this emitter control section.
Wherein: 1-housing, 2-ultrasound transmitting transducer, 3-generating laser
Embodiment
To develop simultaneously embodiment below in conjunction with accompanying drawing, the utility model is described in detail.
The present embodiment provides a kind of sonar guiding escape emitter being applicable to scene of fire guiding escape, can in the megastore caught fire, office building etc. scene of fire, the receiving trap carried for fireman provides ultrasonic signal, and provide laser guidance for fireman, to ensure that fire fighter completes fire-fighting operation or in case of emergency can find an exit fast and accurately, realize guiding escape.
This emitter comprises multiple ultrasound transmitting transducer 2, generating laser 3, circuit board, battery, housing 1, The Cloud Terrace and support.The front end face of described housing 1 is quadrant cambered surface, and the supersonic transducer array formed arranged by the ultrasound transmitting transducer 2 that this arc surface is distributed with by 36 frequency of operation is 25kHz by ad hoc fashion.The arrangement that described supersonic transducer array adopts line array and circular array to combine, be specially: 36 ultrasound transmitting transducers 2 are divided into three parts, the axis along this arc surface is uniformly distributed at equal intervals, forms three rows; Often row's 12 ultrasound transmitting transducers 2 are uniformly distributed at equal intervals along the circumference of this arc surface, as shown in Figure 1.Adopt this kind of arrangement that the transmitting source level of this emitter can be made to reach more than 125dB, receiving range reaches more than 70 meters, launches angle of release and reaches more than 120 degree, be applicable to the open area such as megastore, meet the request for utilization of scene of fire.
For the fireman further for the scene of a fire provides outlets direct, this arc surface is provided with three generating laser 3, three described generating lasers 3 for Emission Lasers ray and is spacedly distributed along the circumference of arc surface.
Described circuit board and battery are positioned at the inside of housing 1, and described battery is that the circuit arranged on circuit boards is powered, and described circuit comprises single-chip microcomputer, signal generator, power amplifier and matching transformer, and it connects as shown in Figure 2.Described Single-chip Controlling signal generator produces the signal of the single-frequency of 25kHz, and this signal is inputed to supersonic transducer array, makes it export powerful ultrasonic signal after being amplified by power amplifier and matching transformer.The switch of described Single-chip Controlling generating laser simultaneously.
Described battery adopts rechargeable battery, the dump energy of single-chip microcomputer Real-time Collection battery, when threshold value lower than its inner setting of the dump energy of battery, sends low electricity alarm.
Described housing 1 adopts water proof and dust proof to design, be specially: because its front end face is workplace, when spraying water for preventing the scene of a fire, water is directly from the upper surface of housing 1 along workplace to dirty, hinder the normal work of ultrasound transmitting transducer and the generating laser be arranged on workplace, form convex edge after being extended forward the front end of described housing 1 upper surface, shelter from its workplace.In like manner, end face is button operation face thereafter, for ensureing that water directly from the upper surface of housing 1 along button operation towards dirty, can not enter housing 1 by button inner, extended back the rear end of described housing 1 upper surface and form convex edge, shelter from its button operation face; Button adopts Waterproof push-button simultaneously.
Be connected with dismountable The Cloud Terrace and support at described housing 1 lower surface, be convenient to the direction and the height that adjust ultrasonic signal and laser.
The principle of work of this emitter is:
Place this emitter in each exit of scene of fire, after fire fighter enters scene of fire, open master switch and the laser lamp gauge tap of emitter, this emitter can send ultrasound wave and 3 laser beams of 25kHz thus.Adjusted transmit direction and the height of ultrasonic signal and laser by The Cloud Terrace and support, make it transmit in the horizontal direction, launch angle of release and cover whole market as far as possible.When fire fighter complete fire-fighting task or run into emergency condition need to withdraw time, if scene of fire affects cannot determine Way out by dense smoke, this emitter just can be fire fighter provides ultrasonic signal and laser beam as guide, time remote, fire fighter relies on ultrasound wave to find outlet, can see time closely that laser beam directly confirms outlet, thus enable finding an exit of fire fighter's fast and reliable, ensure its safety.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
