Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1-2, the present embodiment provides a standing long jump testing system and method:
example one
As shown in fig. 1, a standing long jump testing system includes a controller, a plurality of infrared transmitters and a plurality of infrared receivers.
The infrared emitters are sequentially arranged to form an emitting array for emitting infrared signals; that is, the plurality of infrared emitters are arranged in a daisy chain fashion to form an emitter array. Similarly, the plurality of infrared receivers are sequentially arranged to form a receiving array for receiving the infrared signals; that is, the plurality of infrared receivers are arranged in a daisy chain manner to form a receiving array. The transmitting array and the receiving array are arranged on two sides of the forward extending position of the jump point.
In some embodiments, the spacing between any two adjacent infrared emitters in the emitting array is equal, and the first infrared emitter is arranged on one side of the jump point; in the receiving array, the distance between any two adjacent infrared receivers is equal, and the first infrared receiver is arranged on the other side of the jump point.
Typically, the number of the plurality of infrared transmitters is the same as the number of the plurality of infrared receivers.
The infrared receiver tube is used for controlling the plurality of infrared transmitters and the plurality of infrared receiver tubes to work circularly, judging whether the infrared receiver is blocked or not, and calculating the long jump distance according to the coordinates of the blocked infrared receiver; and if the infrared receiver does not receive the infrared signal in one working period of the infrared receiver, the infrared receiver is considered to be shielded. In one cycle of all the infrared receivers, if the infrared receivers are shielded, the infrared receiver closest to the jump point in all the shielded infrared receivers is used as a reference infrared receiver, and the long jump distance is calculated according to the coordinates of the reference infrared receiver.
In some embodiments, the infrared emitter is an emitting diode, the infrared receiver is a receiving diode, the controller comprises a single chip microcomputer, a plurality of shift registers, a plurality of line decoders, a plurality of infrared receiving driving chips and the like, an anode of the emitting diode is connected with an output end of the shift register, a cathode of the emitting diode is controlled by the line decoder, an anode of the receiving diode is connected with the infrared driving chip, a cathode of the receiving diode is connected with a 5V power supply, and the single chip microcomputer is connected with the plurality of shift registers, the plurality of line decoders, the plurality of infrared receiving driving chips and the like. All the shift registers are connected in a daisy chain mode, namely the last output of the previous shift register is connected with the input of the next shift register, so that the IO ports of the single chip microcomputer can be reduced.
In some embodiments, the standing jump testing system further comprises a power adjustment module for adjusting the transmission power of the infrared emitter. The power adjusting module circularly adjusts the transmitting power of the infrared transmitter, and the transmitting power of the infrared transmitter is circularly adjusted from small to large, so that the test of different spacing distances can be automatically adapted, and the spacing distance is the distance between the transmitting array and the receiving array.
Example two
As shown in fig. 2, a standing jump testing method is applied to the standing jump testing system according to the first embodiment. The standing long jump test method comprises the following steps:
and S1, controlling all infrared transmitters in the transmitting array to circularly work and transmitting infrared signals.
Namely, the power supply of the infrared emitters is periodically and sequentially turned on and off, and all the infrared emitters sequentially and circularly emit infrared signals.
S2, controlling all infrared receivers in the receiving array to work circularly and receiving infrared signals; the work period of each infrared receiver is larger than the period of all the infrared transmitters completing one round of infrared signal transmission.
Namely, the power supply of the infrared receivers is periodically and sequentially turned on and off, and all the infrared receivers are enabled to sequentially and cyclically receive the infrared signals.
Because the work cycle of each infrared receiver is greater than the cycle of finishing a round of infrared signal transmission by all infrared transmitters, when one infrared receiver works, the corresponding infrared transmitter works at least once, thereby ensuring that the infrared signal sent by the corresponding infrared transmitter can be received under the condition of no shielding.
And S3, judging whether the infrared receivers are shielded or not, if the infrared receivers are shielded in one cycle of all the infrared receivers, taking the infrared receiver closest to the jump point in all the shielded infrared receivers as a reference infrared receiver, wherein if the infrared receiver does not receive an infrared signal in a working cycle, the infrared receiver is considered to be shielded.
For example, in one round of operation of all the infrared receivers, 10 infrared receivers are shielded, and the number of the shielded infrared receivers is 056-.
And S4, calculating the long jump distance according to the coordinates of the reference infrared receiver.
And the distance between the reference infrared receiver and the jump point is the long jump distance.
In this embodiment, the infrared transmitter and the infrared receiver do not start at the same time, and both the infrared transmitter and the infrared receiver operate cyclically. For example, there are 300 pairs of infrared transmitters and infrared receivers, with the infrared transmitters being turned on from the 1 st to the 300 th; the infrared receivers are not simultaneously started, and are also started from the 1 st to 300, so that the condition that a plurality of infrared receivers simultaneously receive infrared signals is avoided, and the signal interference of adjacent infrared receivers is avoided.
In some embodiments, the standing long jump testing method further comprises: the power adjusting module circularly adjusts the transmitting power of the infrared transmitter, and the transmitting power of the infrared transmitter is circularly adjusted from small to large, so that the test of different spacing distances can be automatically adapted, and the spacing distance is the distance between the transmitting array and the receiving array.
The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise form disclosed herein and is not to be construed as limited to the exclusion of other embodiments, and that various other combinations, modifications, and environments may be used and modifications may be made within the scope of the concepts described herein, either by the above teachings or the skill or knowledge of the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
