The utility model compared with prior art, has the following advantages and effect: the utility model compact conformation, novelty, adopts light-inductive to replace traditional dot method, makes data more accurate, observes measurement more convenient, make student obtain better Experiment Result.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The radium-shine shaven head of label declaration: 1-, 2-light sensor bar, 3-controller, 4-accelerometer, 5-display screen, 6-printer.
Embodiment
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
As shown in Figure 1, the speed measuring device for Physical Experiment of the present embodiment comprises radium-shine bare headed 1, light sensor bar 2, controller 3 and accelerometer 4, radium-shine bare headed 1, light sensor bar 2 and accelerometer 4 are all electrically connected with controller 3, accelerometer 4 is connected with light sensor bar 2, radium-shine bare headed 1 matches with light sensor bar 2, and controller 3 is provided with display screen 5.
Radium-shine bare headed 1 is red laser pen, is easy to differentiate, and is convenient to observation of students.
Light sensor bar 2 is long is 20cm, and experimental needs, light sensor bar 2 also can be other length such as 30cm.
Controller 3 is also provided with Zoom module and measurement module, is convenient to student and carries out observing and measuring.
Accelerometer 4 is provided with driving-belt, and driving-belt is connected with light sensor bar 2, and accelerometer 4 is numerical-control motor.
The present embodiment also comprises printer 6, and printer 6 is electrically connected with controller 3, is convenient to student and prints experimental data and complete laboratory report.
Adopting said structure, when testing the speed experiment, first opening radium-shine bare headed 1 and accelerometer 4 by controller 3, an accelerated mode is inputted to accelerometer 4, as: " uniform motion " or " uniformly accelerated motion " etc., then input the time interval of an induction point record to light sensor bar 2, start experiment.Accelerometer 4 drives light sensor bar 2 to move by the accelerated mode of specifying, light sensor bar 2 is transferred to controller 3 by the time interval of specifying the position of induction point thereof record sensing radium-shine bare headed 1, controller 3 is shown by display screen 5, student just can see a record strip made a little by display screen 5, student can carry out by Zoom module the distribution situation that amplifying observation gets intensive place ready, distance between simultaneously being measured a little by measurement module, compare traditional manually measuring, data more accurately can be obtained, finally, student prints experiment drawing and data by printer 6, be convenient to laboratory report.
Above content described in this instructions is only to the explanation of the utility model example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment; only otherwise depart from the content of the utility model instructions or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
