When automobile travels on a highway, owing to being run at high speed, the safe distance between vehicles between automobile just seems particularly important.Existing laser ranging proximity-warning device can play certain prevention effect to the crashproof of automobile.But there is the little shortcoming of an investigative range in existing laser ranging warning device.This due to laser be that beam heights is concentrated, and the angle of divergence is very little.When detecting with laser, can only carry out distance measurement to sending a car in a direction, existing laser ranging system just aligns back car and detects, and to its proceeds posterolateral send a car do not have detection and forewarning function.In order to solve the defect of this laser ranging warning device, the utility model proposes a kind of laser ranging proximity-warning device on a large scale, expanding the scope of laser ranging, also can report to the police to backward the sending a car of left and right sides, further ensure that traffic safety.
Summary of the invention
The purpose of this utility model solves existing vehicle laser range finding warning device to there is investigative range little, only aligns back car and detect, and send a car to its proceeds posterolateral and do not have the problem of detection and forewarning function.
The utility model is in order to solve the problem, provide a kind of vehicle laser ranging for preventing collision warning device, this device expands mechanism 2 by infrared laser 1, post lens laser, and quantity is the infrared laser receptor 3 of more than three, find range computing module 4, main control module 6, alarm module and power supply 5 form.
Wherein, described infrared laser 1, post lens laser expands mechanism 2 and infrared laser receptor 3 is all installed on automobile tail, and post lens laser expands mechanism 2 is connected with infrared laser 1 transmitting terminal, make the infrared laser launched by infrared laser 1 be shaped as large-scale line laser to disperse to automobile rear, quantity be more than three infrared laser receptor 3 one of them place towards dead aft with infrared laser 1 is coaxial, all the other are placed towards automobile side rear, for receiving the reflective infrared laser coming from automobile dead aft or proceeds posterolateral, and to range finding computing module 4 transmission of signal,
Range finding computing module 4, for sending Emission Lasers signal to infrared laser 1 and receiving the signal of infrared laser receptor 3, to calculate spacing signal transmission after the spacing of rear or proceeds posterolateral to main control module 6 according to the time gap of Received signal strength launched with pass back the soonest; The spacing signal that main control module 6 sends for receiving range finding computing module, and judge that whether this spacing is lower than safety distance, then send signal to the alarm module being installed on Automobile operation panel if yes, alarm module sends warning to automobile driver after receiving this signal; Described power supply 5 is powered for giving other modules.It is the post lens that size is mated with infrared laser 1 output facula size that post lens laser expands mechanism 2.
Preferred version of the present utility model is, infrared laser receptor is wherein three, respectively 45 °, dead aft and 45 °, right abaft towards left back.
Alarm module described in preferred version of the present utility model is made up of phonetic warning module 7 and light warning module 8, is respectively used to send phonetic warning and light warning to automobile driver.
The beneficial effects of the utility model:
Solve existing vehicle laser range finding warning device and there is the little problem of investigative range, expand mechanism by post lens laser and realize the measuring and calculating to the spacing of sending a car of automobile rear all directions towards multiple infrared laser receptors of automobile rear and proceeds posterolateral, realize, to the large-scale spacing monitoring in car rear, improve the safety in vehicle traveling.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1.
Detailed description of the invention
Below by way of example and by reference to the accompanying drawings detailed explanation and description are carried out to the technical solution of the utility model.
Embodiment 1
As shown in Figure 1, vehicle laser ranging for preventing collision warning device in the utility model expands mechanism's 2, three infrared laser receptors 3 by infrared laser 1, post lens laser, range finding computing module 4, main control module 6, phonetic warning module 7, light warning module 8 and power supply 5 form.
Wherein, described infrared laser 1, post lens laser expands mechanism 2 and three infrared laser receptors 3 are installed on automobile tail, and post lens laser expands mechanism 2 is connected with infrared laser 1 transmitting terminal, make the infrared laser launched by infrared laser 1 be shaped as large-scale line laser to disperse to automobile rear, three infrared laser receptors 3 are respectively towards automobile dead aft, 45 °, left back and the placement of 45 °, right abaft, infrared laser receptor 3 wherein towards automobile dead aft is also coaxial with infrared laser 1, for receiving the reflective infrared laser coming from automobile dead aft or proceeds posterolateral, and to range finding computing module 4 transmission of signal.
Range finding computing module 4, for sending Emission Lasers signal to infrared laser 1 and receiving the signal of infrared laser receptor 3, to calculate spacing signal transmission according to the time gap of launching and receiving signal after the spacing of rear or proceeds posterolateral to main control module 6; The spacing signal that main control module 6 sends for receiving range finding computing module, and judge that whether this spacing is lower than safety distance, if yes then to being installed on the phonetic warning module 7 of Automobile operation panel, light warning module 8 sends signal, sends phonetic warning and light warning after phonetic warning module 7, light warning module 8 receive this signal to automobile driver.Infrared laser 1, infrared laser receiving device 3, range finding computing module 4, master controller 6, phonetic warning module 7 and light warning module 8 are powered by power supply 5, and power supply 5 is provided by automobile storage battery.
Concrete working process is as follows:
When the utility model automobile infrared laser ranging proximity-warning device uses, after range finding computing module 4 sends transmit to infrared laser 1, a branch of infrared laser outwards launched by infrared laser 1, large-scale line laser is shaped as, to increase the scope of laser ranging after this bundle infrared laser expands mechanism 2 by post lens laser.Three the infrared laser receiving devices 3 being placed in the tailstock receive the echoed signal that infrared laser 1 sends laser, give range finding computing module 4 by signal transmission simultaneously.Through range finding computing module 4 calculate after, if automobile and back car spacing are lower than safety distance, then signal transmission to main control module 6.Main control module 6 pairs of phonetic warning modules 7 and light warning module 8 control to warn automobile driver.
The above various module or mechanism are vehicle laser ranging for preventing collision warning device prior art or techniques well known except post lens laser expands mechanism 2, can directly can be realized according to the transformation of the utility model content by existing vehicle laser ranging for preventing collision warning device.Only using 3 infrared laser receptors as a kind of scheme in the utility model embodiment, 4,5 even more infrared laser receptors during practical application, can be used all can to reach the identical technique effect of the utility model.
