The overtaking signal receiver adopts the general silicon photocell with low cost as the probe of the transducer device; the volume of the transducer device of the overtaking signal receiver and an alternating current amplifier is merely equal to the volume of a match box.

Description

Overtaking signal receiver

The utility model belongs to the power actuated vehicle overtaking device.

Present traffic regulation regulation, the notice of need blowing a whistle when overtaking other vehicles front Overtaken Vehicle is when the front vehicle driver hears when blowing a whistle sound and finding that the back has the vehicle request to overtake other vehicles from light deflector, then whether decision is agreed to overtake other vehicles according to the front particular case, and make corresponding reaction, as stretch out one's hand signal.But in order to reduce the noise in city, the horn trumpet volume has been carried out strict restriction, the important location in some city also has the regulation of no tooting, and domestic most of vehicles have all been changed woofer at present.Because the woofer sound transmission apart from weak point, particularly rains when blowing, vehicle window closes, and be difficult to hear blowing a whistle of back vehicle this moment, and light deflector also has the possibility of being blocked by goods.On narrow highway owing to be difficult to receive the signal of overtaking other vehicles traffic accident usually takes place.

In order to solve the problem that the signal of overtaking other vehicles is difficult to accept, the utility model provides a kind of receiving device of overtaking other vehicles.

The signal receiving device of overtaking other vehicles described in the utility model is characterized in that it is made up of sensor device, signal amplifier and signal indicator.The optical signal of overtaking other vehicles that will be received by sensor device transfers electric signal to, amplifies through signal amplifier, by signal indicator signal is become photoacoustic signal and reminds the driver.Said sensor device is made up of silicon photovoltaic cells (1), filter (2), light hurdle (3) and sleeve pipe (4), as shown in Figure 1.Wherein, silicon photovoltaic cells (1) is used for accepting back vehicle need overtake other vehicles the time by a kind of signal transmitter of overtaking other vehicles with the light pulse signal of overtaking other vehicles with fixed frequency that certain angle of divergence was sent, and changes optical signal into electric signal; Light hurdle (3) is used for blocking a large amount of radiation sunshines, and the search angle (11) that guarantees silicon photovoltaic cells is about 30 °, so that receive the optical signal of overtaking other vehicles efficiently; Filter (2) but also filtering sunshine and does not influence the reception of the optical signal of overtaking other vehicles.It is that electric capacity, a diode of three grades of alternate amplifiers adopting integrated circuit, noise filtering or the resistance of forming the amplitude limit follower and diode and shell are formed that said signal amplifier is amplified by preceding two-stage.Signal amplifier adopts the both-end input mode will to be amplified by the electric signal of sensor device input through alternate amplifier, and by the high frequency noise in the electric capacity filter network filtering electric signal of forming in parallel with the feedback resistance in the alternate amplifier, exports through clipper.Said signal indicator is made up of the signal lamp of overtaking other vehicles (1), loud speaker (2), common power amplification circuit, switch (4) and shell (5), as shown in Figure 3.Wherein, power amplifier will amplify from the electric signal of clipper output, is reported to the police by loud speaker (2) and signal lamp (1), need overtake other vehicles with prompting driver back vehicle.

The utility model is simple in structure.Because it adopts the very low common silicon photovoltaic cells of cost as the remote remote measurement sensitive member in the sensor device, and silicon photovoltaic cells can produce up to a hundred milliamperes electric current under the strong sunlight width of cloth is penetrated, pop one's head in for remote measurement remote sensing, this photocurrent of up to a hundred milliamperes has just become noise, the autoexcitation that causes than high-amplification-factor for the noise that overcomes silicon photovoltaic cells and owing to the preceding two-stage of alternate amplifier, the utility model utilizes common electric capacity just to consider the noise except electric signal, thereby simplified circuit, made its signal sensor and signal amplifier add the volume that together has only the matchbox size.The utility model is highly sensitive, be subjected to the interference of bias light very little, 110, in the bias light of 000 illumination (Lux) (sunlight that is equivalent to period of the day from 11 a.m. to 1 p.m hot summer), it still can receive 60 meters with the interior light pulse signal of overtaking other vehicles with fixed frequency, at bias light is 10 illumination (Lux) when (being equivalent to moonlight), and it can receive 200 meters with the interior optical signal of overtaking other vehicles.The utility model is applicable to multiple power actuated vehicle, as all kinds of automobiles, trac., motor bike etc.

Casehistory is as follows:

Signal transducer and signal amplifier are installed in the automobile tail light, as shown in Figure 1.Five-pointed star plug (3) (see figure 3) on the signal indicator is inserted on socket (5) (see figure 1), the connection diagram of each circuit as shown in Figure 2, storage battery (2) on the use automobile is as power supply, selecting model for use is that amplify as preceding two-stage integrated circuit (3), (6) of LM324, three grades of alternate amplifiers that common 3DG6 aerotron (4) amplifies as the 3rd utmost point.When the automobile of back need be overtaken other vehicles, send a branch of light pulse signal of overtaking other vehicles that fixed frequency is arranged by the signal transmitter of overtaking other vehicles, as 200 hertz the optical signal of overtaking other vehicles.At this moment, signal transducer transfers optical signal to electric signal by silicon photovoltaic cells (1), adopt the mode of both-end input that signal is passed to first order amplifier (3),, suppress noise simultaneously to a certain extent and prevent autoexcitation to improve the common mode inhibition capacity of circuit.Because first order amplifier (3) and the shared virtual earth line of second stage amplifier (6) play buffer action admittedly increase resistance (7).Cond (8) at one 200 μ F of first order amplifier (3) inverting input and output termination～400 μ F, it and feedback resistance (9) constitute feedback and filter network, the high frequency noise that filtering is a large amount of, after the same filtering in the second stage, during to mouth, high frequency noise almost reduces to zero, and does not influence the amplification of 200 hertz signal.Overtake other vehicles signal after first order second stage amplifier amplifies, enter the third stage and amplify, it can play buffer action, so as not to because of the variation of load cause before the normal amplification of two-stage.Export to signal indicator through the electric signal that amplifies by the amplitude limit follower that constitutes by resistance (10) and diode (11).Signal indicator adopts Darlington multiple unit tube (12) as power amplification circuit, electric signal is amplified once more, promoting loud speaker (13) reports to the police, the signal lamp (14) of overtaking other vehicles simultaneously is bright, prompting driver back vehicle will be overtaken other vehicles, this driver hears the back of reporting to the police according to actual conditions toggle switch (15), is agreed to overtake other vehicles or disagree with and overtake other vehicles by the expression permission of two kinds of different colours or signal lamp (16) (17) the signal back vehicle that does not allow to overtake other vehicles.When this automobilist need overtake other vehicles, but toggle switch (18) sends the signalisation fwd automobilist that overtakes other vehicles by the signal transmitter of overtaking other vehicles (5).
