Description
Technical field
The present invention relates to a kind of vehicle safety relevant device, especially relate to a kind of vehicle safety sound volume regulating system.
Background technology
Reverse Sensor in the market all is external Reverse Sensor, does not connect together with sound equipment, and the sound equipment music is obscured in sound a buzzer when obstacle is run in reversing meeting and the car, can't clearly remind chaufeur, can not guarantee reversing safety in 100% ground.The patent 95245331.2 of having applied for is the reversing automobile safety alarm device in a kind of electronic measurement field, comprise the display control switch part, left side road probe segment, the right wing probe segment, be installed on portion about the indoor and automobile tail of vehicle drive respectively, it is core control processing apparatus with the micro controller system, utilize ultrasonic ranging principle and microelectronic technique, to be shown on the display control switch apart from 2 meters distance branch left and right sides two-way with interior obstacle of the tailstock, and send different chimes of dooms according to the obstacle distance, but this device is an external device, the chimes of doom that sends will certainly with automobile in sound equipment obscure, cause sense of hearing error.
The patent 00251056.1 of having applied for is a reversing security monitoring device, and it is made up of pick up camera, image control desk, monitoring device.Pick up camera and the rear light of this device are contained in vehicle rear, and image control desk and monitoring device are contained in the appropriate location in the operator's compartment, by the DC power supply of vehicle itself, open automatically when reversing.This patent takes up room greatly, and image controller and monitoring device be installed in the operator's compartment, certainly will take space valuable in the car.
The patent 91212187.4 of having applied for is a kind of vehicle backing safety device.It is made up of safety lever, sliding bar, spring, guide thimble, contact, handle, pulley, stay cord, loudspeaker, switch.Be installed in the railway carriage afterbody, handle and switch before the reversing in the operation operator's compartment, safety lever stretches out outside the rear cabinet immediately, when safety lever touches obstacle, sends chimes of doom in the operator's compartment, reminds the driver to note, and emergency brake avoids accident to take place.But this external device mainly relies on the contact of safety lever to transmit signal, and safety lever is not suitable for long-term use in that repeatedly the collision back service life can be very short.
Summary of the invention
Purpose of the present invention be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of take up room little, warning effect obviously, the vehicle safety sound volume regulating system being convenient to produce in enormous quantities.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of vehicle safety sound volume regulating system is characterized in that, comprises distance measuring sensor, micro controller system, LED lamp and digital regulation resistance, and described micro controller system is connected with distance measuring sensor, LED lamp, digital regulation resistance respectively;
Described distance measuring sensor is measured the distance between self and the obstacle during reversing, and an echoed signal that receives is sent to micro controller system, and described micro controller system judges whether to receive echoed signal, if yes, control LED lamp is bright, if not, the LED lamp is in and extinguishes state; Described micro controller system is converted to the echoed signal that receives digital signal and is transferred to digital regulation resistance, and described digital regulation resistance converts thereof into the resistance control signal and amplifies to control resistance value in the sound equipment.
Described distance measuring sensor is HC-SR04 ultrasonic ranging sensor.
Described micro controller system is the STC12C5A60S2 micro controller system.
Described digital regulation resistance is the X9C103 digital regulation resistance.
Described distance measuring sensor is installed in the afterbody shell place of vehicle.
Described digital regulation resistance is installed in audio device for vehicle inside.
Compared with prior art, the present invention has the following advantages:
1: it is little to take up room: digital regulation resistance will be installed in acoustical equipment inside, directly link to each other with the audio regulating control, can not take interior space more than ground, and distance measuring sensor also be mounted in the car outside, so this device can not cause a bit influence to absolutely empty of car.
2: the warning effect is obvious: type of alarm is to remind the occupant by the size of music in the automobile car, does not worry mixed tin of the interior concert of car and chimes of doom, and the warning effect is more obvious, and safety factor is higher.
3: be convenient to produce in enormous quantities: distance measuring sensor and digital regulation resistance manufacture craft are simple, and be very easily integrated, integrated, and various functional circuits are combination and simplification easily, sound construction, steady quality, repeatability and good reliability; Being easy to produce in enormous quantities, is the Eltec development, for installing and package technique all provides condition easily on the surface.
Description of drawings
Fig. 1 is structured flowchart of the present invention;
Fig. 2 is physical circuit figure of the present invention;
Fig. 3 is the working timing figure of distance measuring sensor of the present invention.
The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
