Description
One, technical field
The utility model relates to a kind of laser measurement apparatus for obtaining evidence, especially laser velocimeter is fixedly mounted on speed limit highway section one sides such as highway, the travel speed of motor vehicles is measured, and the measurement apparatus for obtaining evidence that over-speed vehicles is taken.
Two, background technology
Hypervelocity is first killer in the traffic hazard.Therefore the detection that the motor-driven speed of a motor vehicle of specific region is carried out continuous and effective is very important.
The laser velocimeter that present traffic department generally uses is the principle that adopts laser ranging.Laser ranging (be electromagnetic wave, its speed is 300,000 kilometer per seconds) is by to testee emission laser beam, and receives the reflection wave of this laser beam, writes down this mistiming, determines the distance of testee and test point.Laser velocimeter is the laser ranging of driving vehicle being carried out having for twice specified time interval, obtains this period expert and sails the displacement of vehicle, thereby obtain the translational speed of this driving vehicle.This mode need keep aiming at all the time within a certain period of time tested vehicle, has strengthened the working strength of survey crew, and is tired easily, and can not realize the robotization seizure, can not measure continuously, can not measure automatically by vehicle, cause certain difficulty for law enfrocement official's evidence obtaining all.Chinese patent 02207336.1 disclosed a kind of over-speed vehicles laser velocimeter adopts 2 laser detectors to solve these problems, but it is used for handheld operation, as to be used for fixing its power supply of formula be continuous working, power consumption is big, battery short need often replacing service time, and these knotmeter cost height all not to driver's warning function, make people turn a blind eye to speed limitation board.
Three, summary of the invention
The purpose of this utility model is to solve above-mentioned problems of the prior art, a kind of laser measurement apparatus for obtaining evidence is provided, it can carry out robotization to being positioned at vehicle on arbitrary track, installation site, successional seizure is measured, and have the rate accuracy height, simple in structure, cost is low, automatic shooting, handle convenient, characteristics such as efficient is high, overspeed prompting in real time.
The purpose of this utility model is achieved in that it comprises and is installed on highway and other speed limit highway sections and the laser velocimeter and the digital camera of the certain level distance of being separated by, the laser detector that wherein has 2 separated by a distance, parallel installations in the laser velocimeter, power supply adopts dry cell, power switch is connected in series by lead with acoustic control amplifier and vibration amplifier, and laser velocimeter is connected with a flashlamp with digital camera by signal wire.
The socket that also has the high-capacity and high-speed storer on the utility model, laser velocimeter is connected with storer by data line with digital camera, and testing result and content of shooting are stored in the storer, can be accessed by the personnel on duty and handle after gathering again.
Having interface can pass through wireless network card or optical cable or telephone wire on the utility model is connected with the traffic specific computer network, the control center that the testing result and the shooting content of laser velocimeter and digital camera can be sent to traffic police department in real time is so that policeman on duty is understood timely the overspeed of vehicle phenomenon and handled.
Adopt the beneficial effect of such scheme to be: 1) its laser velocimeter of adopting has the laser detector of 2 separated by a distance, parallel installations, system can record the speed of vehicle according to known laser interfascicular distance, therefore can carry out automatic, continuous monitoring, after fixed installation on the road, need not the aiming control of survey crew; 2) judged whether that by acoustic control amplifier and vibration amplifier vehicle will pass through, controlled emission or stop laser beam, need not launch useless laser continuously, can prolong the time that dry cell is kept work, reduced operating cost and change the battery number of times with this; 3) flashlamp is luminous plays the caution reminding effect to the driver, informs that in time it exceeds the speed limit, and supervises its deceleration safe driving; 4) by wireless network card or optical cable or telephone network, be connected with the traffic specific computer network, data in time are sent to control center, can be implemented in the real-time fast network overall treatment of line, efficient is higher.
Four, description of drawings
Fig. 1 is a functional-block diagram of the present utility model;
Fig. 2 is a scheme of installation of the present utility model;
As follows to the label declaration in each width of cloth accompanying drawing:
The 1-power switch; 2-acoustic control amplifier; The 3-vibration amplifier; The 4-laser velocimeter; The 5-flashlamp; The 6-digital camera; 7-traffic specific computer network; 8-high-capacity and high-speed storer; 9-control center.
Five, embodiment
A kind of fixed over-speed vehicles laser velocimeter apparatus for obtaining evidence of the utility model, its structure can see from Fig. 2 that it comprises laser velocimeter 4, digital camera 6, acoustic control amplifier 2, vibration amplifier 3, flashlamp 5, high-capacity and high-speed storer 8 etc.
The laser detector that has 2 separated by a distance, parallel installations as shown in Figure 2 in the laser velocimeter 4 of Cai Yonging, the effect of laser detector is to transmit and receive laser beam, its measuring principle is as follows: by restrainting collimated laser beams to the direction emission two vertical with vehicle heading, reception is through driving vehicle laser light reflected signal, measuring vehicle drives to the used time of another laser beam through a laser beam, then can calculate the speed of vehicle according to known laser interfascicular distance.
This device is fixedly mounted on laser velocimeter 4 and digital camera 6 on highway and other speed limit highway sections by the support of certain altitude, promptly several monitoring points are set at a certain distance in highway one side, certain shooting distance of need being separated by between laser velocimeter 4 and the digital camera 6, acoustic control amplifier 2 is installed on the laser velocimeter 4, vibration amplifier 3 is placed on the ground below the laser velocimeter 4, high-capacity and high-speed storer 8 is installed on the socket, will install by wireless network card or optical cable or telephone wire and be connected with the traffic specific computer network.
Illustrate that in conjunction with Fig. 1 this device course of work is as follows: turn on the power switch 1, the effect of acoustic control amplifier 2 and vibration amplifier 3 is whether emission of lasering beam of control laser velocimeter 4, in case vehicle is close, when the sound that produces reaches certain decibels or ground vibration and reaches certain value, power connection with laser velocimeter 4, emission of lasering beam, test the speed to catching automatically by the vehicle of monitoring point, the conversion back is compared with the critical velocity that sets in advance and is judged whether hypervelocity as calculated, in case hypervelocity just produces a signal and opens digital camera 6 and flashlamp 5 automatically, digital camera 6 is collected evidence by the digital type static image of taking vehicle, warning function is played to the driver in flashlamp 5 luminous backs, simultaneously testing result and content of shooting are stored in the storer 8, access by the personnel on duty and to handle again after gathering, and can testing result and shooting content be sent to the control center 9 of traffic police department in real time by traffic specific computer network 7, so that policeman on duty is understood timely the overspeed of vehicle phenomenon and is handled.
