Abstract
The utility model provides a fire-fighting evacuation indicating lamp provided with sound-controllable brightness comprising an indicating lamp and a control panel connected with the indicating lamp. The control panel is provided with a voltage stabilization circuit used for supplying the power, and comprises a sampling circuit, a comparison circuit, and a brightness adjusting circuit, which are sequentially connected together. The sampling circuit comprises a sound gatherer, a signal amplification circuit, and a signal conversion circuit, which are sequentially connected together. The fire-fighting evacuation indicating lamp is advantageous in that the brightness of the evacuation indicating lamp can be changed according to the sound intensity; when no one walks, the external sound intensity is weak, therefore the brightness of the indicating lamp can be lowered, and the power consumption can be reduced; when people walk, the external sound intensity of the indicating lamp can be enhanced, therefore the brightness of the indicating lamp can be enhanced, and the evacuation indication effect can be improved; by adopting the novel control method of adjusting the brightness of the evacuation indicating lamp according to the sound intensity, the defects of the conventional indicating lamps such as fixed brightness and high energy consumption can be overcome.
Description
Technical field
The utility model relates to the fire-fighting equipment field, but is specifically related to a kind of fire-fighting evacuation indicator light of brightness acoustic control.
Background technology
Along with the remarkable lifting of the national fire-fighting consciousness of China, the fire-fighting evacuation indicator light has become indispensable fire-fighting equipment.But no matter existing fire-fighting evacuation indicator light still is night by day, and its brightness is constant always, has caused great energy waste.
The utility model content
In order to solve the deficiency of above-mentioned technology, but the purpose of this utility model provides a kind of fire-fighting evacuation indicator light of brightness acoustic control, and it has solved the unalterable deficiency of brightness in the past.
The technical scheme that its technical problem that solves the utility model adopts is:
But a kind of fire-fighting evacuation indicator light of brightness acoustic control, it comprises indicator light and the control board that is connected with indicator light, described control board is provided be used to the voltage stabilizing circuit that power supply is provided, described control board comprises that successively being used for of connecting gather sound intensity signals sampling circuit, be used for relatively the comparison circuit of sound intensity signal and the brightness regulating circuit that is used for regulating the indicator light luminance state, and described sample circuit comprises sound collector, signal amplification circuit and the signaling conversion circuit that connects successively.
Described sound collector is sound intensity transducer or microphone.
Described brightness regulating circuit is current regulating circuit or pwm pulse regulating circuit.
Be provided with delay circuit between described comparison circuit and the sample circuit.
The beneficial effects of the utility model are, determine whether that according to intensity of sound needs change the brightness of evacuating indicator light, and when no personnel walked about, the sound intensity in the indicator light external world was just very weak, so the brightness of indicator light can turn down, and reduce energy consumption; When personnel walked about, the sound intensity in the indicator light external world just increased, so the brightness of indicator light also strengthens raising evacuation indicating effect.Therefore adopt and thisly adjust the new type of control method of evacuation indicator light brightness in real time according to sound intensity size, overcome that existing indicator light brightness is fixed, not energy-conservation deficiency.
Description of drawings
Fig. 1 is logical schematic of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
Referring to Fig. 1, the utility model comprises indicator light 4 and the control board that is connected with indicator light 4, described control board is provided be used to the voltage stabilizing circuit 5 that power supply is provided, described control board comprise successively connect be used for gathering sound intensity signals sampling circuit 1, be used for comparing the comparison circuit 2 of sound intensity signal and the brightness regulating circuit 3 that is used for regulating indicator light 4 luminance states, described sample circuit 1 comprises the sound collector 11 that connects successively, signal amplification circuit 12 and signaling conversion circuit 13, the sound intensity signal that sound collector 11 is collected, amplify processing by signal amplification circuit 12, be input to signaling conversion circuit 13 again through the signal after amplifying, this sound intensity signal is converted to analog signal, be input to comparison circuit 2, adopt the utility model to determine whether that needs change the brightness of indicator light 4 according to intensity of sound, when no personnel walk about, the sound intensity in indicator light 4 external worlds is just very weak, therefore the brightness of indicator light 4 can be turned down, and reduces energy consumption; When personnel walked about, the sound intensity in indicator light 4 external worlds just increased, so the brightness of indicator light 4 also strengthens, and improved and evacuated indicating effect, had overcome constant, the not energy-conservation deficiency of brightness of existing indicator light 4.
Described sound collector 11 is sound intensity transducer or microphone.Can adopt sound intensity transducer to carry out the collection of sound, also can adopt microphone to carry out the collection of sound, select according to the parameter request of indicator light 4.
Described brightness regulating circuit 3 is current regulating circuit or pwm pulse regulating circuit.Brightness regulating circuit 3 can adopt current regulating circuit, by regulating the operating current of indicator light 4, make indicator light 4 present the state that brightness changes, equally also can adopt the pwm pulse regulating circuit, by the adjusting of output pulse signal, indicator light 4 is carried out brightness regulation.
Be provided with delay circuit 6 between described comparison circuit 2 and the sample circuit 1, delay circuit 6 be set, be implemented in the sound intensity signal that collects strong degree after, guarantee that indicator light 4 can keep this luminance state to continue the long period.
The circuit that the utility model adopts is this area circuit commonly used.
Embodiment should not be considered as restriction of the present utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
