[0033] The reference detection position of the object to be detected can be a common detection position of the object to be detected, or a key detection position determined according to the structure of the object to be detected. The plurality of detection sites of the object to be detected are other detection positions apart from the reference detection position of the object to be detected, and can be distributed in a plurality of directions of the object to be detected.

[0034] In an embodiment, the detection host 10 can comprise a host body, which is provided with the GNSS positioning module 11, the ultrasonic positioning module 12 and the communication module 13. The GNSS positioning module 11 can adopt a GNSS positioning antenna, which can be an active GNSS positioning antenna provided with a battery supply unit, or a passive GNSS positioning antenna.
