It is detected again, it is also possible to not strike metope and no longer be detected rebound information, it is also possible to which the height for hitting metope is insufficient
And infrared signal detection plane is no longer pass through after springing back, or even occur after vollyball impinges upon correct wall section but springs back not
The case where detecting plane by infrared signal.It so cannot be simply by 2 septums secundum when routine processes signal separates number
Disconnected number is denoted as once acting wall dig, and the signal partition number for odd-times occur also can not be simply after subtracting 1 again except 2 obtain
Out to wall dig number, because successfully corresponding signals twice most to wall dig separate every time, and it is unsuccessful to wall
Dig either separates without signal or corresponding signal partition, and thus do not become function is even-times to wall dig number
When, signal partition total degree be finally also even number, and correctly to wall dig movement may also only generate a signal every
It is disconnected, therefore greater than the signal partition that after vollyball diameter, master control borad is counted at a distance from infrared signal detection plane is between metope
The corresponding relationship that number and person under test's dig number do not determine.Certainly, in the partition of signal twice for introducing master control borad record
After time interval, it a degree of can reflect the relationship between signal partition number and person under test's dig number, for example arranging
Ball for the first time by infrared signal detect plane after in a relatively short period of time again by infrared signal detect plane, have it is larger can
It can be primary completely to wall dig movement, even so or in the presence of complicated uncontrollable factor exist certainly, it cannot be accurate
React person under test's dig number.
