A coding circuit is set in said remote control transmitter, the output end of the coding circuit connects with a directional emitting circuit, a receiving circuit is set in the receiver, the output of the receiving circuit connects with a switch decoder, the switch decoder connects with the coding switch control end of the voice circuit, the output end of the voice circuit connects with a loudspeaker. The utility model auto-send out the prompting language of each traffic signs to the driver, reminds the driver and prevents the peccancy running caused by inattention of the driver or the traffic sign unclear.

Description

Vehicle mounted traffic sign prompting instrument

Technical field

A kind of traffic sign suggestion device that is used on the vehicles of the utility model.

Background technology

Along with the prosperity day by day of traffic, traffic administration is more and more tighter, and the thing followed is that various traffic signs are also more and more, present traffic sign all is that the form with nameplate is arranged on the traffic main artery, the driver will notice at any time that in the process of moving a carelessness just may be broken rules and regulations slightly.

Summary of the invention

The technical problems to be solved in the utility model provides a kind ofly can send the vehicle mounted traffic sign prompting instrument of voice suggestion from the trend driver.

The technical scheme that addresses the above problem is: the utility model is provided with the remote control transmitter that is contained in the traffic sign highlight, is contained in the receiver in the vehicles, be provided with coding circuit in the described remote control transmitter, the coding circuit output terminal is connected with the directional transmissions circuit, described receiver is provided with receiving circuit, the receiving circuit output terminal is connected with the switch code translator, the switch code translator is connected with the code switch control end of sound circuit, sound circuit output termination loudspeaker.

Further scheme is: described directional transmissions circuit is the infrared emission circuit that is provided with modulation circuit, and the infrared emission head of infrared emission circuit is provided with and is no less than two infrared transmitting tube.

Principle of work of the present utility model is: the language of different traffic signs is stored in the sound circuit of receiver, for example " note; the front is the one-way road ", " no overtaking ", " the place ahead speed limit " etc., and be provided with respectively and various language corresponding codes signals, be stored in the switch code translator.During use (referring to Fig. 1), remote control transmitter is installed in the place that to carry out the traffic sign prompting, and make emitting head face toward the vehicles must through regional area, send and the corresponding coded signal of traffic sign language, when vehicles process transmitter emitting area, after receiving coded signal, decipher through the switch decoding scheme, the suggestion voice signal that the output of control sound circuit is corresponding with decoding, and send language to the driver by loudspeaker, behind this zone, phonetic order automatically terminates.

The further scheme of the utility model is no less than two infrared transmitting tube in the emitting head setting of infrared emission circuit, can form a fan-shaped surface of emission by a plurality of infrared transmitting tubes like this, makes the remote signal of emission can cover certain zone.

The utility model can send the language of various traffic signs from the trend driver, in time reminds the driver, avoids not concentrating or unclear the driving against traffic regulations of causing of traffic sign because of driver attention.

The further scheme of the utility model can guarantee the necessary overlay area that transmits.

Embodiment

Referring to Fig. 2, Fig. 4, the remote control transmitter 1 that this example is contained in the traffic sign highlight is provided with coding circuit and the modulation transmitter that is made of the PT2262-IR integrated circuit, modulate emission signal output part DOUT is connected with Infrared High-Power power valve 4, this example is provided with 6 Infrared High-Power power valves, PT2262-IR transmitting chip geocoding input end has " 1 ", " 0 ", " open circuit " three kinds of states, the data input is determined by " 1 " " 0 " two states, integrated circuit OSC1 end and OSC2 end are circumscribed with the resistance of decision radiating circuit carrier frequency, coding is from output terminal DOUT output, and the coded signal of this routine DOUT end output is modulated on the 38KHZ carrier wave.

The infrared receiving terminal output terminal that is contained in the receiver in the vehicles is equipped with the switch code translator of demodulator circuit by amplifying circuit, this routine switch code translator is by forming with the PT2272 remote control decoding special IC of PT2262-IR chip pairing use, this circuit be provided with demodulator circuit and with various traffic sign language corresponding codes memory circuits, PT2272 demodulation coding output terminal D0-D5 is connected with the code switch control end A0-A5 of ISD2500 audio record circuit, the sound circuit output terminal is connected to loudspeaker, also is provided with the Mike who is connected with the sound circuit input end.

By Mike various traffic sign languages being input to the receiver sound circuit also stores within it, to deposit the switch code translator in various language corresponding codes again, the receiver that is contained on the vehicles receives the transmitter coding signal transmitted, amplify, demodulation is with the coding contrast of storing in the switch code translator, output decoded signal, decoded signal is input to sound circuit code switch control end, the promptly exportable suggestion voice signal corresponding with coding.

The scrambler of this routine transmitter 1 and receiver code translator are respectively the PT2272 chips that PT2262 and pairing are used, the scrambler PT2262 of transmitter 1 is the low-power consumption coding circuit that CMOS worker's core is made, use with the PT2272 pairing, has battery saving mode, the PT2272 that uses with scrambler PT2262 pairing is the remote control decoding special IC, this chip adopts the manufacturing of CMOS technology, maximum is gathered around the three-state address pin with 12, can support the nearly coding of individual address, 531441 (or 312), coding be scanned possibility to make it to mate so can greatly reduce the conflict of coding and roach method.The ISD2500 audio record circuit has anti-outage property, E in the built-in 480K sheet ²PROM, in the time of can guaranteeing to cut off the power supply, the voice messaging that records can not lost.

Referring to Fig. 3, the emitting head of infrared remote-control emitter 1 is provided with 6 infrared transmitting tubes 4, the Adjustable device tabula rasa 3 of scalable emission subtended angle is housed on the infrared emission head, this routine Adjustable device tabula rasa is contained in the infrared emission tube side part, be used to control the emission subtended angle of infrared emission signal, prevent that it is transmitted in the zone that should not point out.
