Description

Shuttle run measurement system {SYSTEM FOR MEASURING SHUTTLE RUN}

The present invention relates to a shuttle run measurement system, and more particularly, to a system capable of simultaneously measuring a plurality of people with a slight error in measuring and evaluating a subject's ability to perform a reciprocating run using a sensor and a microprocessor device. .

In general, the shuttle run (round-trip) to measure the distance of about 20 meters in the gymnasium, such as the gymnasium to draw a line, put the mark on both ends and measure the ability of the subject's shuttle run. As follows.

The subject waits on the 20-meter start line and, when the start signal sounds, jumps to the other side of the 20-meter line. At this point, the subject must extend one foot on or outside the return point marked 20 meters. If the subject arrives on the other side before beeping, wait until the beeping sound before leaving. This measurement process repeats the interval until the subject can no longer hold it. If you do not reach the 20-meter mark before the beeper, you will be admitted that you arrive late on time if you arrive at the next 20 meters quickly before the beep, but 20 meters until two or more consecutive beeps. If no mark is reached, the measurement is terminated. After the measurement is completed, the measurer records the cumulative number of times the subject has repeated the section.

In the conventional shuttle run measurement method, a sound device such as a CD or a cassette tape is turned on, and the test subjects run a shuttle (shuttle run) according to a constant beep and arrange a measurer (supervisor) corresponding to the measurement target to arrive at the return point. Whether or not the naked eye has been checked one by one and the number of runs has been measured depending on the memory of the supervisor. In this conventional method, the larger the number of people to be measured, the larger the number of people must be arranged, so that manpower loss is generated and the measurement must be dependent on the sensor's sense and memory.

In order to solve the above problems, the shuttle run measurement system according to the present invention uses a photoelectric sensor to detect the arrival of the return point of the subject and digitizes it, and then provides a function of outputting the result to the display device. The purpose.

The shuttle run measurement system according to the present invention is a non-contact detection of the arrival of the subject by a photoelectric sensor fixed by the support installed on both sides of the plurality of lanes formed in parallel to detect the detection unit and the measurement to transmit the detection signal to the control unit And a control unit for controlling the system and a display unit for displaying a signal received from the control unit, performing a procedure for transmitting a signal for outputting an instruction and a measurement result to the display unit for each lane.

In addition, the photoelectric sensor is formed of a light-transmitting unit and a light-receiving unit integrally on one side and a reflecting plate formed on the other side of the photoelectric sensor, or a light-transmitting unit is formed on one side, and a light-receiving unit is formed on the other side, respectively, and is configured to be transmissive. .

In addition, the procedure for transmitting a signal for outputting the instruction and the measurement result for the measurement performed by the control unit to the display unit is the step of transmitting the start signal for the first start and repeated start of each section and the detection signal from the sensor The step of receiving input and the step of judging whether the measured object arrived in time and the time of arrival in time, the delay time is cleared, the time of arrival signal and the repetition time counter up signal to the display device and the time of arrival do not arrive in time Step of counting up delay and determining whether delay is 2, and if delay is 2, sending measurement end signal and counter stop signal to display device, and ending procedure and delay is not 2 In this case, the delayed arrival signal and the counter-up signal are transmitted to the display device once, and a series of procedures are repeated to repeat the section. It characterized in that it comprises a system.

In addition, the procedure for transmitting a signal for outputting the instruction and the measurement result for the measurement performed by the control unit to the display unit for setting the measurement time and transmitting the start signal and detecting the arrival signal during the set measurement time And repeating a procedure, a procedure of raising a counter, and a procedure of outputting a counter signal to a display device, and transmitting an end signal.

The display unit may include a digital display device for displaying a counter, a speaker for audibly displaying a start signal, an arrival signal, and a measurement end signal, and a lamp for visually displaying a start signal, an arrival signal, and a measurement end signal. Characterized in that.

In addition, the lamp of the display unit is characterized in that it is installed on the upper end of the sensing unit provided at both ends of each lane, in order to facilitate the user to check during the measurement.

The controller may further include a lamp check function for temporarily supplying power to all lamps by a switch operation in order to test whether there is an abnormality of the lamps.

The shuttle run measurement system according to the present invention can reduce the error of several tens of centimeters that can occur during visual measurement to less than one millimeter by using the photoelectric sensor, and the number of interval repetitions is countered by the digitized signal, which may depend on the memory of the measurer. In addition, it is possible to eliminate the errors that occur in one case, and it is possible to measure whether the shuttle run is performed by several people with one system, and the reliability of the measurement results is high, which requires the reliability of various civil service tests, college entrance exams, selection of players, etc. It can be used for physical verification.

Referring to the preferred embodiment of the shuttle run measurement system according to the present invention in detail as follows.

1 is a view showing a schematic diagram of a shuttle run measurement system according to the present invention.

According to the present invention, the other shuttle run measurement system includes a detection unit 100 that detects whether or not the subject (runner) of the shuttle run (reciprocation) has reached the return point by a non-contact sensor 100 and a controller 200 for controlling the system. And a display unit 300 for displaying various instructions and results, the specific configuration of which is as follows.

In general, a long and parallel lane 10 is formed to allow a plurality of subjects to reciprocate in a flat and wide space for shuttle run measurement. Marked at both return points of the lane 10, the return point is about 20 meters away, and the lane 10 is generally about 2 meters wide. The distance and width may vary depending on the measurement purpose, the space condition, and the sensitivity of the photoelectric sensor 110.

The detection unit 100 is configured to detect the arrival of the subject through the photoelectric sensor 110 is fixed by the support 120 is installed on both ends of the plurality of lanes 10 formed in parallel. The support 120 may use a general tripod for fixing a camera widely used, it may be able to use a support fixed to the floor in a pile method in the place where the shuttle run measurement system according to the invention is always installed. In the case of measuring a plurality of subjects, the support 120 should be installed at an appropriate position so that the return point of each lane is matched and the optical axis emitted from the photoelectric sensor is arranged in a line.

As shown in FIG. 2, the photoelectric sensor 110 may be formed in a reflective type in which a light transmitting part 111 and a light receiving part 112 are integrally formed on one side and a reflecting plate 113 is formed on the other side. The light transmitting unit 111 and the light receiving unit 112 formed on one side of one photoelectric sensor 110 and the reflecting plate 113 formed on the other side of the other photoelectric sensor 110 function as a pair, but the light receiving unit 112 ) And a body having a low reflectance between the reflector and the reflector 113, that is, a body part such as a leg of a subject to block light, generate a detection signal.

When the reflective type is configured as described above, the detection distance is limited to a maximum of 5 meters. However, when the reflective plate 113 is large, the optical axis between the light transmitting portions 111 and 112 and the reflective plate 113 is easily adjusted. There is an advantage that it is easy to process the wiring to be connected.

As shown in FIG. 3, the photoelectric sensor 110 may include a light transmitting unit 110 at one side and a light receiving unit 112 at the other side of the photoelectric sensor 110. In this case, the light transmitting portion 111 formed on one side of the one photoelectric sensor 110 and the light receiving portion 112 formed on the other side of the other photoelectric sensor 110 function as a pair, but the light transmitting portion 111 and When the body part of the subject blocks light between the light receivers 112, a detection signal is generated.

In the case of the transmissive type, it is difficult to adjust the optical axis between the light transmitting part 111 and the light receiving part 112, and the wiring has to be processed twice, but the detection distance is up to 20 meters and the accuracy is very high. .

Shuttle run measurement system according to the present invention to determine the first start, section departure, the end of the measurement, such as the arrival and the arrival time, round trip frequency counter, delay count counter, the end of the measurement, etc. A control unit 200 for processing a signal for output to the display unit for each lane is included, and includes a display unit 300 for displaying a signal received from the control unit, the display unit 300 is included.

The method of measuring using the shuttle run measurement system according to the present invention is a method of measuring endurance and quickness by measuring the accumulated number of round trips without delaying the reciprocating two or more times in a specific section (hereinafter referred to as mode 1) and simply designated There is a method of testing how many round trips can be made to any section during the time (hereinafter referred to as mode 2). To implement this, the controller 200 may include a computer or a microprocessor in which a program for executing the following procedure is embedded. It includes, and the specific procedure for transmitting a signal for outputting the instruction and the measurement result for the measurement performed by the control unit 200 to the display unit is as follows.

The mode 1 method and the mode 2 method can be programmed and embedded together, and the flow of the program by the mode 1 can be easily selected by operating a switch or the like as shown in FIG. And transmitting a start signal for repetitive start of each section (S100), receiving a detection signal from the detection unit 100 (S110), and determining whether the measured object arrives in time (S120). And if it arrives within the time, clear the delay time (S121), and transmit the arrival time signal and the repetition time counter up signal to the display device (S122); and if the time does not arrive within the time step, counting up the delay time (S130). And determining whether the delay number is 2 (S140), and if the delay number is 2, transmitting the measurement end signal and the counter stop signal to the display device (S141), and ending the procedure (S142). If the number of annual non-2 transmits a one-time arrival signal and a delay counter-up signal to the display device, and a step (S150) to re-execute a set of procedures for the repeat section.

In more detail, the step of transmitting the start signal for the first start and the repeated start of each section (S100) is that the subject transmits the first start signal after delaying about 10 seconds after waiting for departure in front of his lane. The buzzer sounds to the speaker of the display unit 300, and the red light for the start indication is turned on.

After receiving the detection signal (S110) and determining whether the measured object arrives in time (S120), if the arrival time arrives within the time, the delay is cleared (S121), and the arrival time signal and the repetition time counter up signal are displayed. In step S122, when the measured object arrives at the return point in time and there is one delay arrival, the delay time is cleared when the next section is reached in time. This is to end the measurement only when there are two consecutive delayed arrivals. After the delay is cleared, display the counter up on the corresponding lane on the monitor and turn on the green indicator of the corresponding lane.

Next, if it does not arrive in time, the counter goes through a step of counting up the delay (S130) and determining whether the delay is 2 (S140), which is a measurement end signal to terminate the measurement when the delay is 2 And transmitting the counter stop signal to the display device (S141) and terminating the procedure (S142). The monitor of the display unit 300 maintains a final counter (section repeat count), and the speaker and the lamp provide a measurement end signal. After the end of the measurement, the recording may be recorded by hand and may be by a well-known digital data storage method that is well known.

If the number of delays is not 2, the number of delays will be 1, so that the measurement is not terminated. The delayed arrival signal and the counter up signal are transmitted to the display device, and the series of procedures are repeated to repeat the section (S150). Done. In this case, the value of the number of delays to determine whether there are two consecutive delays and the counter of how many times the interval is repeated should continue to accumulate in memory until the system is shut down.

The mode 2 method is simpler and simpler than the mode 1 method, and the number of round trips within the time while allowing the subject to run a random section (10m, 15m, 20m, 30m, etc.) for a fixed time It is a counter.

In the mode 2 method, as shown in the flowchart shown in FIG. 5, a step of setting a measurement time (S200), a step of transmitting a start signal to a display unit (S210), and a procedure of detecting an arrival signal during the set measurement time (S221) And repeating a procedure of up the counter (S222), and outputting a counter signal to the display unit (S223) and transmitting an end signal to the display unit (S230). Is programmed for precise and extensive settings from 0.1 seconds to 9999 hours and is embedded in a computer or microprocessor.

The display unit may be implemented by various conventionally known display apparatuses capable of expressing an instruction for measurement and a measurement result, but preferably, a digital display device 310 for displaying a counter and a start signal, an arrival signal, and an end of measurement. By including a speaker 320 for visually displaying a signal and a lamp 330 for visually displaying a start signal, an arrival signal, and a measurement end signal, a digital display device and an audio signal through the visualization speaker by the lamp are included.
