The preconfigured test requirements include: measured position, measured speed, measured angle and measured direction. The measured position represents the collision occurrence position, namely, the measured object is required to perform a collision test at the measured position. The measured velocity represents the collision velocity, namely the running velocity of the measured object at the moment of performing the collision test is required to reach the measured velocity. The measured angle represents a collision angle, namely the running angle of the measured object at the moment of performing the collision test is just the measured angle. The measured direction represents the collision direction, namely the running direction of the measured object at the moment of performing the collision test is just the measured direction. It should be noted that, since the collision occurs between two or more measured objects, the number of measured speeds may be greater than or equal to 1, for example: the measured speed can be one or more, if the number of the measured speeds is 1, the collision of two or more measured objects with the same measured speed is shown; if the number of the measured speed is greater than 1, the measured speed also carries indication information, where the indication information is used to indicate the measured speed corresponding to the measured object, for example: aiming at a measured object A and a measured object B, the measured speed of the measured object A is required to be a, and the indication information of the measured speed can comprise the mark of the measured object A; the measured speed of the measured object B is required to be B, and the indication information of the measured object B can include the identifier of the measured object B. Similarly, the number of the measured angles and the measured directions can be greater than or equal to 1.
The collision test instruction issued by the control equipment can play a role in triggering a collision test process and can control the track equipment and the tested object to cooperatively complete the collision test, so that the control equipment can coordinate and control the whole collision test process.
