Abstract
The invention discloses an automatic recording instrument for a track and field score, which is a high-accuracy and low-cost instrument for automatically recording a running score of a student. The two ends of a finishing line in each athletic track are both provided with vertical columns, and more than two pairs of photoelectric emitting tubes and receiving tubes are arranged on the vertical columns. The instrument is connected with a timer control circuit and is used for stopping timing of the timer. Compared with the manual timing mode, the automatic recording instrument has the advantages of high accuracy and low expense. Compared with the high-speed photography timing method, the automatic recording instrument has the advantage of low cost.
Description
The invention belongs to the physical education articles for use, promptly write down the run instrument of achievement of student automatically.
Up to now, the device of test record running time has two types.One type of high-speed photography that is equipped with for national above athletic meeting equipment that clocks automatically another kind ofly clocks by stopwatch for artificial hand.The former clocks accurately, and artificial cost is few.But because cost is high, general school can't use, and is exactly provincial athletic meeting, has also adopted the artificial method that clocks because there is not this facility.Though latter's cost is low, there is artificial cost big, the shortcoming that the precision that clocks is not high.
The object of the invention just is to above-mentioned weak point, provides a kind of accuracy high, the cheap athletics achievement instrument that clocks automatically.
For achieving the above object, all be provided with column at the two ends of the finishing line of every runway, photoemission cell, receiving tube are housed more than two pairs on the column.It and timer control circuit link, and are used to stop the timing of timer.Radio transmitting apparatus is housed on starting pistol.Radio system and timer control circuit link, and make its starting constantly can be synchronous with the shot of issuing an order.
The invention has the beneficial effects as follows: clock with manual work and compare, have the accuracy height, the advantage that expense is low.Compare with the high-speed photography chronometry, have cheap advantage.
Below in conjunction with accompanying drawing and an embodiment the present invention is described further.
Accompanying drawing 1 is runway pillar construction figure.
Accompanying drawing 2 is the time device structure chart.
In Fig. 1,1. column, 2. photoemission cell, 3. photoelectric receiving tube.
In Fig. 2,4. time device, 5. electric wire.
Have severally to photoemission cell (2), receiving tube (3) on the column (1) at runway finishing line two ends, receiving tube (3) connects time device (4) with electric wire (5).
Operation principle of the present invention is following: when starting pistol rang, the transmitting set on the rifle started time device (4) simultaneously, begins to clock; When the people crossed terminal point, because body blocks receiving tube (3), time device (4) stopped clocking.It is several to receiving tube (3) that column (1) go up to be installed, and can effectively prevent to clock because of crossing stopping that finishing line causes before portable.So just can satisfy " body " and cross the regulation that finishing line stops to clock.
" the automatic chronograph of athletics achievement " provided by the invention uses in middle-size and small-size athletic meeting, can improve the accuracy of timing, and reduces artificial cost; In physical education, be used to test student's dash achievement,, can also alleviate teacher's labour intensity, practice thrift instructional blocks of time except improving the accuracy.
Claims (3)
1. one kind " the automatic chronograph of athletics achievement " is made up of column (1) photoemission cell (2), receiving tube (3), electric wire (5), time device (4); The column (1) that it is characterized in that the runway two ends is equipped with photoemission (2), receiving tube (3) on the column.
2. according to claim 1 or 2 said " the automatic chronograph of athletics achievement ", it is characterized in that said photoemission (2), receiving tube (3) are equipped with more than two pairs on column (1).
3. time device according to claim 1 (4) is characterized in that: time device has wireless electric starter in (4), and the outside is connected with receiving tube (3) with electric wire (5).
