Description of drawings
Below in conjunction with accompanying drawing and preferred implementation the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of generating laser in the utility model;
Fig. 3 is the structural representation of laser pickoff in the utility model.
Embodiment
As shown in Figure 1, collision car speed measurement mechanism of the present utility model comprises laser beam emitting device 1, laser receiver 2 and controller 3, interconnects by communication bus and power lead between described laser receiver 2 and the controller 3; Described laser beam emitting device 1 is used for sending two bundle parallel lasers, and described laser receiver 2 is used for receiving the two bundle parallel lasers that described laser beam emitting device sends; Described controller 3 is used for calculating the speed of tested automobile 4.Wherein, distance between described laser receiver and the laser beam emitting device is 1-50 rice, safe distance between general laser receiver and the laser beam emitting device is arranged on about 15 meters, when this when adjusting, the focal length of laser beam emitting device is also done corresponding adjustment, and the laser that makes it to launch can focus on laser pickoff.
In the time of between tested automobile 4 is by laser beam emitting device 1 and laser receiver 2, because stopping of tested automobile 4, laser receiver 2 can can't receive the first bundle laser that laser beam emitting device 1 sends, when automobile moves on, laser receiver 2 can can't receive the second bundle laser that laser beam emitting device 1 sends, mistiming between controller 3 can record, when carrying out test experiments, only need gap length 300mm with two bundle parallel lasers divided by the mistiming, just the speed of tested automobile 4 as can be known.Be rectilinear motion when crossing laser receiver 2 and laser beam emitting device 1 in order to ensure tested automobile 4, can a vehicle collision traction track 5 be set between laser receiver 2 and laser beam emitting device 1, this vehicle collision traction track 5 is mutually vertical with the laser that laser beam emitting device 1 sends.
As shown in Figures 2 and 3, described laser beam emitting device 1 is provided with two laser emission ports 11, and pitch of holes is 300mm; Described laser receiver 2 is provided with two laser pick-off holes 22 of mutually mating with described laser emission port 11, and pitch of holes is 300mm.When the automobile that is tested the speed is restrainted parallel laser through two, can stop that laser can't correlation.At this moment, the moment of controller reception laser cut-off signal is not identical.According to the formula of speed=distance/time, the parallel distance of two bundle parallel lasers is fixing 300mm, and controller calculates a mistiming according to the moment that two bundle laser disconnect, and just can calculate the velocity amplitude of tested speed automobile at last.
Described laser receiver can be the adjustable laser pickoff of receiving sensitivity; Described laser receiver can be the adjustable laser pickoff of receiving sensitivity; Described controller can operate for Programmable Logic Controller and by touch-screen.So, the laser focal capable of regulating that laser beam emitting device sends, the receiving sensitivity of laser pickoff is adjustable.Controller adopts the Programmable Logic Controller (being commonly called as PLC) of industrial special use, and the equipment operating panel adopts the programmable touch screen of industrial special use.Than common Single-chip Controlling, whole speed measuring device has reached other requirement of shelter of technical grade, has very high stability and antijamming capability like this.By the writing and setting parameter of director demon, make whole equipment have full-automatic and automanual continuous speed measuring function simultaneously.
Below the preferred embodiment of the invention is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the invention spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
