Abstract
The utility model provides a miniature receiver for overtaking signals used for motor vehicles, which is composed of a band pass filter, a photoelectric sensor, a signal amplifier, a monitoring device, and a signal indicator. An optical signal with a specific wavelength, and a fixed frequency or speech modulation is chosen by the filter, and magnified by the amplifier, a message or an indication is transmitted to drivers by a loudspeaker and an indicating lamp, and the drivers decide the driving state according to the condition, or prompt an overtaking purpose by a lamp at the back of the motor vehicle.
Description
The utility model belongs to the miniature signalling apparatus of overtaking other vehicles of automobile-use.
In order to tighten traffic management, guarantee traffic safety, new traffic regulation regulation must be played steering indicating light and the signal of blowing a whistle when power actuated vehicle is overtaken other vehicles.But a lot of luxury car sealing properties are better, add the pneumatic noise when running at high speed, and are difficult to not hear the sound of blowing a whistle of overtaking other vehicles, the time the improper traffic accident that causes of overtaking other vehicles arranged.And automobile is blown a whistle and has been brought serious noise pollution.In order to address the above problem, the utility model provides a kind of miniature signal receiving device of overtaking other vehicles.
The miniature signal receiving device of overtaking other vehicles described in the utility model mainly is made up of the logical coated lens of band, photoelectric commutator, signal amplifier, audiomonitor, signal indicator and shell.By will overtake other vehicles signal or be converted to electric signal of photoelectric commutator, amplify the rear drive loud speaker through signal amplifier, and have indicator lamp to remind the driver simultaneously through the infrared signal of language modulation.The lens of coating film treatment (1) photodiodes (2) shielded leads (3) bases (4) and shell (6) are formed receiving transducer, as shown in Figure 1, wherein, convex lens (1) are used for receiving fixed frequency that the back vehicle sends by the miniature signal transmitter of overtaking other vehicles or through the optical signal of language modulation, after the bias light decay of the logical anti-reflection film of the band that is coated with by lens surface with other frequency spectrum, be transferred to photodiode (2), photodiode (2) is converted to electric signal with optical signal and connects signal amplifier through shielding wire.Like this, it is quite little that receiving transducer just can be done, and is fixed on the vehicle afterbody and do not affect the appearance.Amplifier section then can be placed in the interior tool box of car.The pressure ring of receiving transducer (7) both can fixed lens (1), probe can be fixed on again on the tailstock boxboard (8), and the pressure ring part of protracting can play and shelters from sunshine and antifouling effect.Photodiode seat (4) is a bakelite car system, it be used for fixing photodiode and and casing insulation, base (4) is fixed on the housing rear end with flathead screw (5), housing (6) is a metallic material car system, it has good capability of electromagnetic shielding.Signal amplifier (electrical schematic diagram such as Fig. 2) is by two-stage preamplifier (BG

The utility model is simple in structure, and volume is small and exquisite, has adopted ZDUL as photo-electric conversion element, cooperates filter lens to form photoelectric probe; Have good spectrum character and higher sensitivity, can suppress the interference of spuious bias light preferably, have the electroacoustic frequency band of broad again, to adapt to the requirement of language transmission.The hole that whole probe only needs to make a call to 25 millimeters of diameters at the tailstock just can be installed.Amplifier is contained in another housing internal fixation optional position in car.Amplifier is contained on the miniature printed circuit board, and power driving circuit YZ23 is fixed on the amplifier outside, so that fixing interdigital radiating gill.Because amplifier has higher gain, make ranging coverage daytime greater than 50 meters, be applicable to C-class and other all kinds of power actuated vehicles.
This miniature signal receiving device working process is as follows:
When front vehicle need be overtaken other vehicles, open transmitter supply, signal transmitter sends the infrared light pulse of a fixed frequency, or with the optical signal of language form modulation.Receptor is a normally open when driving, when receiving extraneous signal, becomes electric signal through preposition amplification by photodiode converts, and power gain promotes monitoring loudspeaker, simultaneously indicating device D
