Abstract
A vehicle-borne alarm used for avoid collision at the intersection of curved roads comprises an antenna (1), a radio frequency receiving/emitting unit (2), a collision avoidance processing unit (3), an audio output unit (4), a photoelectric display unit (5) and a power supply (6). The collision avoidance processing unit processes data signals received and demodulated by the radio frequency receiving/emitting unit on a real-time basis and sends the processed signals to the audio output unit and the photoelectric display unit. The vehicle-borne alarm has the advantages that (1) the alarm can provide acoustic alarming signals, optical alarming signals, etc. for a driver; and (2) the structure is simple, the operation is convenient and the electricity consumption is low.
Description
Technical field:
The utility model relates to vehicle-mounted mountain area detour intersection collision prevention panalarm.
Background technology:
Along with the increase at full speed of China's motor vehicle number, traffic hazard also increases thereupon, and particularly detour confluce in mountain area crashes also all the more outstanding.Only avoid vehicle in the generation of detour confluce, mountain area accident or reduce and take place to seem unable to do what one wishes all the more by driver's vision merely, address this problem at present and seemed very urgent.
Summary of the invention:
The purpose of this utility model provides a kind of vehicle-mounted mountain area detour intersection collision prevention warning device.
A kind ofly be used for vehicle-mounted mountain area detour intersection collision prevention alarm, it comprises antenna 1, radio frequency receipts/bill unit 2, collision prevention processing unit 3, audio output unit 4, photoelectric display unit 5 and power supply 6, and said collision prevention processing unit is delivered to audio output unit and photoelectric display unit respectively after handling in real time through the data-signal that produces behind the radio frequency receipts/bill unit receiving demodulation.
Good effect of the present utility model:
1, can provide alerting signals such as sound, light to the driver, not influence driver's field of view, can improve driver's notice;
2, adopt electronic equipment to be subjected to boisterously to influence very little and can realize that automatic collision prevention reports to the police;
3, the utility model is simple in structure, and is easy to operate, power consumption is little.
Description of drawings:
Fig. 1 is a theory diagram of the present utility model.
Fig. 2 is a specific embodiment of the utility model:
Embodiment:
Below in conjunction with accompanying drawing the utility model is described in further details.
This device adopts the clock control mode, regularly receiving and transmitting signal.Antenna 1 among Fig. 1 is the positioning transceiving antenna.When power connection, the course of work of accepting state is: if antenna 1 receives the signal that the vehicle-mounted collision prevention alarm of the other side sends, by radio frequency receipts/bill unit 2 it is demodulated into digital signal, being input to collision prevention processing unit 3 again handles in real time, audio output unit 4 and photoelectric display unit 5 will be through the live signal that collision prevention processing unit 3 is handled (demonstrations) outputs of being reported to the police, and the prompting driver dodges the forward intersection vehicle.When power connection, the course of work of emission state is: collision prevention processing unit 3 produces one group of code, sends through radio frequency receipts/bill unit 2, positioning transceiving antenna 1 with pulse mode.The 6th, power supply.
In Fig. 2, antenna E1 is that microstrip antenna, its input and output impedance are 50 Ω.
Wireless data transmission module U1 constitutes less radio-frequency receipts/bill unit, realizes the modulation and demodulation to data.During reception, radiofrequency signal enters the link that less radio-frequency receipts/bill unit receives from antenna, and is demodulated into digital signal, by wireless data transmission module TXD pin (4 pin) pass to the collision prevention control module and do checking treatment; During transmission, (this car) data are produced by the collision prevention processing unit, and the RXD pin (3 pin) that is sent to wireless data transmission module by serial ports is modulated to radiofrequency signal, launches from antenna.Single chip computer AT 89C51 (U2) and reset circuit, clock circuit constitute the collision prevention processing unit, realize the processing to transceive data.Said collision prevention processing unit is when receiving, and first verification receives whether signal is setting signal, and there is the intersection vehicle in the words that the are the place ahead of just reporting to the police.In cycle, receive a plurality of uniformity signal at official hour, show the forward intersection vehicle number by the photoelectric display unit; When emission, every a fixing cycle, emission set of pulses signal is used for the forward intersection vehicle detection.Capacitor C 1, resistance R 1 and switch S 1 constitute the reset circuit of single-chip microcomputer U2, realize the reset function to system; Crystal oscillator X1 and capacitor C 2, C3 constitutes the clock circuit of single-chip microcomputer U2.Hummer U3, NPN type triode T1 and resistance R 2 constitute audio output unit, realize audio alarm.When receiving the signal of opposite intersection vehicle, 21 pin of single-chip microcomputer produce the conducting that high level is controlled triode T1, hummer work.Charactron D1, D2 constitute the photoelectric display unit, show the forward intersection vehicle number.2,3,4,7,8,9,10 pin of charactron are the data segments of charactron, and 1 pin is the gating section of charactron, controls charactron D1 according to the front vehicles number that single-chip microcomputer calculates, and D2 shows corresponding number.
