Description

Anti-collision alarm for cars on the express highway
The present invention relates to the anti-collision alarm for cars on the express highway, also applicable to the collision-proof alarm of other road up train except that express highway.
Utility model patent numbers 95213879.4, the applying date 950531, invention and created name " automobile high-speed safety traffic intelligent observe and control instrument " comprises rang sensor and speed sensor, and the two is connected with primary controller by cable separately, and primary controller is connected with telltale by cable.Rang sensor is made up of near infrared projector, the side's of elephant telecentric beam path receptor and amplifier thereof, speed sensor is Doppler's numeral velometer, and the oscillator that primary controller is transmitted by generation, emission power amplifier, pulse compression coded modulation circuit, decoding circuit, phase comparator, buffer amplifier, oscillator and microprocessor are formed.The observing and controlling distance of this utility model patent is in 200 meters, thereby detection range is near, a little less than the antijamming capability, the false alarm rate height, can not under the various environmental conditionss of vehicle operating, survey the running condition of front vehicles like clockwork, particularly descend, can not use in severe environmental conditions such as rain, mist, snow, can not dynamically show the front vehicles number continuously, car is transmitted the various run signal of front truck and Ben Che backward.
The object of the present invention is to provide the anti-collision alarm for cars on a kind of express highway, this device detection range is far away, anti-various interference, under the various environmental conditionss of vehicle operating, survey the running condition of front vehicles like clockwork, dynamically show the front vehicles number continuously, and with the information of the various information of the front truck that received and Ben Che continuously rearwards vehicle transmit, take various state of kinematic motions to travel for chaufeur scientific basis is provided, when vehicle enters the danger range scope and overtakes other vehicles, this device sends alerting signal respectively, make it have the enough time to remove the dangerous condition, prevent that vehicle from smashing and personal casualty, guarantee the safety of personnel and vehicle.
The object of the invention is achieved through the following technical solutions: signal conditioning display alarm control box is equipped with detection alarm and the warning device of overtaking other vehicles, and the two connects by up-downgoing coding master cock.Detection alarm device comprises emitter, receiver, with emitter, receiver and switch circuit bonded assembly controller, mouth bonded assembly vehicle number telltale with transmitter and receiver, the input end of the output termination demodulation amplifying circuit of the shunt of receiver, the mouth of demodulation amplifying circuit respectively with the receiver module of receiver, comparison controller, range display, the emergency alarm circuit connects, respectively its receiver is carried out automatic gain control, the information of adjusting the distance is carried out distance conversion and range of a signal, signal is compared control, the control annunciator, the mouth of comparison controller is connected with the emergency alarm circuit with range display respectively, difference command range indication range and emergency alarm distance range, the demodulation amplifying circuit, the cable connection of switch circuit and receiver, the mouth of switch circuit is connected with the emergency alarm circuit with range display respectively, and shown range data is carried out gating and sent emergency alarm; The warning device of overtaking other vehicles comprises emitter and connected mission controller, and receiver and connected reception controller with reception controller bonded assembly annunciator, receive controller and are connected with mission controller.
The present invention compared with prior art has following technique effect:
Detection range is far away.Show its detection range greater than 0 to 900 meter according to this device on-board running actual measurement, the relay detection range is greater than 0 to 4000 meter.
Anti-various interference, no false-alarm.Because up, downlink coding controller is the encoding and decoding master cock, it can make the address of the encoding and decoding of the vehicle on the different operations track have nothing in common with each other easily, thereby has eliminated the phase mutual interference of the vehicle arrangement on the different tracks up hill and dale.Simultaneously frequency range is selected, whole device is the composite radar structure, has carried out pulse encoding control and has adopted filtering technique, has selected controller, has solved the interference of other factors effectively.
Can be continuously dynamically, standard separates the relative distance that inerrably shows between front vehicles number and detection vehicle.Detection alarm device has adopted transmitting-receiving pulse code signal load mode separately, front truck car backward sends the pulse code signal, this signal has comprised the relative distance of front vehicles, the front vehicles number, back car receiver shows the signal of receiving and driving enters in the danger range scope and sends alerting signal, make chaufeur have time enough to take crashproof measure, to guarantee the high speed and the safety of hot-short.
Can with the pulse code signal received and the position signal of apparatus of the present invention place vehicle etc. backward car transmit continuously, this is because in the detection alarm device among the present invention emitter is arranged.
The problem that can avoid many high-speed cruising cars to take simultaneously to overtake other vehicles action when overtaking other vehicles accurately and effectively and get into an accident.The pulse code signal load mode that the warning device of overtaking other vehicles also adopts sending and receiving to separate.Vehicle when taking to overtake other vehicles and take action clicks the button of overtaking other vehicles by chaufeur, when the emission actv. indicator lamp of overtaking other vehicles is bright, can take the action of overtaking other vehicles.This car this moment homodromous vehicle in 200 meters scopes sends the frequency modulation on pulse coding signal of overtaking other vehicles, receive the vehicle of the alerting signal of overtaking other vehicles, even alerting signal is pressed the button of overtaking other vehicles in the extended period overtaking other vehicles, button, can not send out the alerting signal of overtaking other vehicles, the emission actv. indicator lamp of overtaking other vehicles does not work, and does not allow to take to overtake other vehicles action yet, accomplish in the same way to have only a car just can take the action of overtaking other vehicles in 200 meters scopes.
The present invention is not descended by adverse weather conditions such as the influence of the various environmental conditionss of vehicle operating, particularly rain, mist, snow, can guarantee the safety of vehicle high-speed cruising yet.This installation cost is low, and is easy and simple to handle, can Fast Installation.
