Abstract
The present invention relates to an anticollision radar for car. It is characterized by that said invention uses the infrared ray scanning light waves to implement automatic detection of pavement obstruction and automatic braking operation of car, and uses super large scale integrated circuit to control automatically transmission, receiving and data treatment. Its detection portion adopts special-purpose infrared transmission and receiving probes, so that it features high sensitivity, high anti-interference property and without limitation of natural environment (condition), therefore it can effectively preventing running car from collision, and can protect driver and passenger.
Description
The present invention relates to the anti-pre-device of a kind of automobile, particularly a kind ofly can predict road barrier thing, the automobile collision avoidance radar of autobrake automatically.
What the anticollision device of present employed automobile did not all have an accident except that guard or anti-collision air bag initiatively prevents pre-equipment, and it is to reach the prevention purpose by driver's driving quality and experience.This anticollision device has only when accident takes place and just can work, and speed is when fast, mostly be that car crash accounts for the overwhelming majority, even also the residual body of limb is broken for the lighter, so this anti-pre-device effect and not obvious, nowadays the car speed of express highway is very fast, snow during as low visibility, rain, greasy weather are easy to get into an accident, at this moment under the situation, this mechanical anti-pre-(guard) device is passive, and role is little.
The objective of the invention is to propose a kind of automatic detection road barrier thing that has, the automobile collision avoidance radar of autobrake, it can solve self preventing in advance and driver and conductor's personal safety of self-propelled vehicle effectively, thereby reduces and avoid the generation of accident.
The object of the present invention is achieved like this: adopting infrared ray dedicated probe and ultra-large data integrated circuit chip and supporting circuitry and annex formation, this IC chip is a kind of duplexing integrated circuit with the function of transmitting and receiving, and possesses the mode of operation of various control output with the control executive circuit.When with the switch connection power supply of circuit, circuit is just started working, at this moment infrared emission head is launched the infrared scan light wave of certain frequency, when obstacle occurring on the road surface, the place ahead that car travels, the infrared scan light wave is by an obstacle institute reflected back part, this infrared scan light wave by backspace is received by infrared receiving terminal, change abundant one-tenth electric signal after receiving this infrared scan lightwave signal, after amplifying, flow to chip (IC1) at last through frequency discrimination again and carry out frequency discrimination once more, amplify, data handing, when determining to be the frequency of this machine emission, just export a control signal, make the solid-state relay conducting, electromagnetic valve work, realize autobrake, automobile halts, and has so just realized preventing accident among possible trouble, have only when obstacle is removed, braking just can stop.
Owing to adopted technique scheme; make the anti-pre-device of automobile realize that electronics prevents automatically; reduce or stopped the incidence of accident; protect automobile to avoid infringement and personal safety effectively, the restriction that autobrake reaction (response) speed is fast, accurate, infrared ray is not subjected to weather and natural environment.
Fig. 1 is an electrical schematic diagram of the present invention.
Fig. 2 is structure distribution figure of the present invention.
Below in conjunction with accompanying drawing this structure of tool of the present invention and working process are specifically elaborated.
The present invention is made up of power circuit (IC1), emitting head (HF), reception head (HJ), a mu balanced circuit (IC2), control circuit (GD) and electromagnetic valve (DF).When running car need be monitored with the obstacle of road pavement of the present invention, (K) closes a switch, power connection, galvanic current of output is pressed and is supplied with chip (IC1) after (IC2) tests pressure, through outer transmitting probe (HF), infrared receiver probe (HJ) and transistor (T), (LED) luminous indictor tube and (GD) solid-state relay make its normal operation, the electric signal of the certain frequency of chip (IC1) output is at this moment given infrared emission head (HF), infrared emission head (HF) just goes out the infrared scan light wave by given frequency emission, at this moment infrared receiving terminal is in the reception mode of operation, obstacle (people appears on the road surface, the car thing, animal etc.) time, the infrared scan light wave is promptly by an obstacle reflected back part, infrared receiving terminal (HJ) just receives this by the infrared scan light wave of backspace, through amplifying, send into behind the frequency discrimination and carry out once more the frequency discrimination amplification in the chip (IC1), when being confirmed to be the scanned infrared light wave at last, just send the automatic guidance instruction number of selling, at this moment transistor (T) conducting, (LED) luminous indicating diode is bright, the solid-state relay conducting, electromagnetic valve (DF) work, automobile brake.Former car gas (braking) valve (SO) of stopping is use in parallel with electromagnetic valve (DF), when not needing the present invention to reflect control automatically, can manually brake, and is artificial and also can use simultaneously automatically, also can use respectively, is independent of each other.(CZ) be the power supply power supply base, it uses with the power supply source coupling.Its glancing impact is limited to when obstacle is removed or and just can stops braking when closing (disconnection) power supply of the present invention.
Claims (3)
1, anti-collision device for automobile, the particularly a kind of automobile collision avoidance radar that can survey the road barrier thing automatically, it is made up of infrared probe, chip (IC1), control solid-state relay (GD), electromagnetic valve (DF), it is characterized in that probe is the reflective detection of infrared waves, and is subjected to chip (IC1) control.
2, automobile collision avoidance radar according to claim 1 is characterized in that braking electromagnetic valve (DF) and former braking air valve (SO) use in parallel.
