Abstract

Provided are a system and a method for positioning a suspected article. The system includes a truss indicating mechanism defining a coordinate system having X, Y and Z directions perpendicular to each other. The truss indicating mechanism includes a first direction moving rail disposed on a truss body in one of the three directions; a second direction moving rail movably disposed on the first direction moving rail in a another of the three directions, the second direction moving rail is movable in the first direction relative to the first direction moving rail; and a ranging indicating device movably disposed on the second direction moving rail, the ranging indicating device is configured to be movable in the second direction relative to the second direction moving rail, and is configured to feed back position information of the suspected article in a to-be-inspected cargo by using coordinate information of the coordinate system.

First claim

What is claimed is:

1 . A system for positioning a suspected article, comprising: a truss indicating mechanism configured to define a coordinate system, wherein the coordinate system has an X direction, a Y direction and a Z direction which are perpendicular to each other; wherein the truss indicating mechanism comprises:
a truss body; a first direction moving rail disposed on the truss body and arranged in a first direction among the X direction, the Y direction and the Z direction; a second direction moving rail movably disposed on the first direction moving rail and arranged in a second direction among the X direction, the Y direction and the Z direction, wherein the second direction moving rail is configured to be movable in the first direction relative to the first direction moving rail; and a ranging indicating device movably disposed on the second direction moving rail, wherein the ranging indicating device is configured to be movable in the second direction relative to the second direction moving rail, and is configured to feed back position information of the suspected article in a to-be-inspected cargo by using coordinate information of the coordinate system.

2 . The system for positioning the suspected article according to claim 1 ,
wherein the position information of the suspected article comprises: coordinate position of the suspected article in the coordinate system, and/or a distance of the suspected article relative to the ranging indicating device in the Z direction.

3 . The system for positioning the suspected article according to claim 1 ,
wherein the first direction is the X direction, and the second direction is the Y direction.

4 . The system for positioning the suspected article according to claim 1 ,
wherein the first direction is the Z direction, and the second direction is the X direction or the Y direction.

5 . The system for positioning the suspected article according to claim 1 , further comprising:
a positioning platform defining one and same coordinate system as the truss indicating mechanism, wherein the positioning platform is configured to place the to-be-inspected cargo on a plane jointly defined by the X direction and the Y direction; wherein the positioning platform comprises an X-direction limiting baffle arranged in the X direction and a Y-direction limiting baffle arranged in the Y direction, and the X-direction limiting baffle and the Y-direction limiting baffle are configured to jointly define a position corresponding to a coordinate origin of the coordinate system.

6 . The system for positioning the suspected article according to claim 5 ,
wherein the positioning platform is provided with a power mechanism configured to move the to-be-inspected cargo on the positioning platform in at least one of the X direction and the Y direction; and/or wherein the positioning platform is provided with a non-power mechanism configured to move the to-be-inspected cargo on the positioning platform in at least one of the X direction and the Y direction.

7 . The system for positioning the suspected article according to claim 5 ,
wherein the ranging indicating device is a laser ranging indicator.

8 . The system for positioning the suspected article according to claim 5 , further comprising:
a CT-type cargo inspection mechanism defining one and same coordinate system as the truss indicating mechanism, wherein the CT-type cargo inspection mechanism is configured to scan the to-be-inspected cargo placed on the positioning platform, and is configured to feed back the position information of suspected article in the to-be-inspected cargo.

9 . The system for positioning the suspected article according to claim 5 , further comprising:
a suspected article placing position disposed close to the positioning platform, wherein the suspected article placing position is configured to place the suspected article taken out from the to-be-inspected cargo; and a non-suspected article placing position disposed close to the positioning platform, wherein the non-suspected article placing position is configured to place a non-suspected article taken out from the to-be-inspected cargo.

10 . The system for positioning the suspected article according to claim 5 , further comprising:
a control mechanism configured to manipulate the ranging indicating device and/or the positioning platform.

11 . A method for positioning a suspected article, which is applied to the system for positioning the suspected article according to claim 1 , comprising:
placing the to-be-inspected cargo at a truss indicating mechanism, so that a position of the to-be-inspected cargo corresponds to the coordinate information of the coordinate system defined by the truss indicating mechanism; and moving the ranging indicating device in at least one of the first direction and the second direction relative to the truss indicating mechanism, so as to determine the position information of the suspected article through the ranging indicating device.

12 . The method for positioning the suspected article according to claim 11 ,
wherein the position information of the suspected article comprises: coordinate position of the suspected article in the coordinate system, and/or a distance of the suspected article relative to the ranging indicating device in the Z direction.

13 . The method for positioning the suspected article according to claim 11 ,
wherein the first direction is the X direction, and the second direction is the Y direction.

14 . The method for positioning the suspected article according to claim 11 ,
wherein the first direction is the Z direction, and the second direction is the X direction or the Y direction.

15 . The method for positioning the suspected article according to claim 11 , wherein the system for the suspected article further comprises: a positioning platform defining one and same coordinate system as the truss indicating mechanism, wherein the positioning platform is configured to place the to-be-inspected cargo on a plane jointly defined by the X direction and the Y direction; wherein the positioning platform comprises an X-direction limiting baffle arranged in the X direction and a Y-direction limiting baffle arranged in the Y direction, and the X-direction limiting baffle and the Y-direction limiting baffle are configured to jointly define a position corresponding to a coordinate origin of the coordinate system; and
wherein in the method for positioning the suspected article, the placing to-be-inspected cargo at a truss indicating mechanism further comprises:
placing the to-be-inspected cargo on the plane of the positioning platform jointly defined by the X direction and the Y direction, and
positioning a position of the to-be-inspected cargo on the positioning platform by using the X-direction limiting baffle and the Y-direction limiting baffle.

16 . The method for positioning the suspected article according to claim 15 , wherein the positioning platform is provided with a power mechanism configured to move the to-be-inspected cargo on the positioning platform in at least one of the X direction and the Y direction; and/or wherein the positioning platform is provided with a non-power mechanism configured to move the to-be-inspected cargo on the positioning platform in at least one of the X direction and the Y direction; and
wherein in the method for positioning the suspected article, the placing the to-be-inspected cargo at a truss indicating mechanism further comprises: moving the to-be-inspected cargo relative to the positioning p
