Abstract

A security inspection system and method are disclosed. The security inspection system comprises: at least one baggage cart comprising at least one compartment for containing a baggage and configured to pass through a scanning channel; and a scanning device configured to inspect the baggage cart passing through the scanning channel and containing the baggage, at least based on a traveling speed of the baggage cart.

First claim

We claim:

1. A security inspection system, comprising:
at least one baggage cart comprising at least one compartment for containing a baggage and configured to pass through a scanning channel; and
a scanning device configured to inspect the baggage cart passing through the scanning channel and containing the baggage, at least based on a traveling speed of the baggage cart;
wherein the baggage cart comprises:
a sensing sub-system configured to sense at least one physical attribute information of the baggage carried by the baggage cart; and
a communication module configured to send the at least one physical attribute information to the scanning device,
wherein the scanning device is further configured to adjust a scanning parameter for the baggage cart based on the at least one physical attribute information.

2. The security inspection system of claim 1 , wherein the at least one physical attribute information comprises at least one of a weight of the baggage; one of a density, an electron density, an equivalent atomic number and a material composition of a part of interest in the baggage; and a size and a location of the part of interest in the baggage; and
wherein the scanning parameter comprises at least one of a radiation dose, a radiation energy, a scanning speed, a beam exit frequency, numbers of views, numbers of CT scanning angles, a distribution of CT scanning angles.

3. The security inspection system of claim 1 , wherein the communication module is further configured to transmit information on the traveling speed of the baggage cart to the scanning device, and the scanning device is further configured to adjust the scanning parameter based on the traveling speed of the baggage cart.

4. The security inspection system of claim 3 , wherein the traveling speed of the baggage cart is set depending on at least one of a weight and a size of the baggage.

5. The security inspection system of claim 1 , wherein in response to detecting that the baggage has no danger by the scanning device, the baggage cart is configured to travel to a baggage counter and push a checked-in baggage in the compartment to a baggage carousel, or move the checked-in baggage onto the baggage carousel by an external mechanism.

6. The security inspection system of claim 1 wherein in response to detecting that the baggage has no danger by the scanning device, the baggage cart is further configured to travel to an exit of a passenger security check channel while carrying a carried-on baggage, and wait until the passenger security checking is completed.

7. The security inspection system of claim 6 , wherein the baggage cart is further configured to travel to a boarding gate by following a passenger.

8. The security inspection system of claim 1 , wherein in response to detecting that the baggage is suspicious by the scanning device, the baggage cart is further configured to travel to a manual inspection area, so as to enable performing a manual unpacking inspection on the baggage by an inspector.

9. The security inspection system of claim 8 , wherein the baggage cart further comprises:
a locking device coupled to a door of the compartment and configured to lock the door in response to detecting that the baggage is suspicious by the scanning device.

10. The security inspection system of claim 1 , wherein the locking device is further configured to lock the door of the compartment in response to a security inspection starting signal.

11. The security inspection system of claim 1 , wherein the scanning device is further configured to inspect a plurality of baggage carts simultaneously, if the plurality of baggage carts pass through the scanning channel in parallel.

12. The security inspection system of claim 1 , wherein the baggage cart comprises a first compartment and a second compartment, wherein the first compartment is configured to contain a checked-in baggage and the second compartment is configured to contain a carried-on baggage.

13. A security inspection method, comprising steps of:
receiving, by at least one baggage cart, identification information and flight information of a passenger, and loading the baggage of the passenger into at least one compartment of the baggage cart;
passing through a scanning channel of a scanning device by the baggage cart, in response to a security inspection starting signal;
inspecting the baggage cart that passes through the scanning channel and contains the baggage, at least based on a traveling speed of the baggage cart, so as to obtain a scanning result;
storing the scanning result in association with the identification information and flight information of the passenger;
sensing, by the at least baggage cart, at least one physical attribute information of the baggage carried by the baggage cart and transmitting the at least one physical attribute information to the scanning device; and
adjusting a scanning parameter for the baggage cart, based on the at least one physical attribute information.

14. The security inspection method of claim 13 , further comprising the step of:
transmitting information on the traveling speed of the baggage cart to the scanning device; and
adjusting, by the scanning device, the scanning parameter based on the traveling speed of the baggage cart.

15. The security inspection method of claim 14 , wherein the traveling speed of the baggage cart is set depending on at least one of a weight and a size of the baggage.

16. The security inspection system of claim 13 , further comprising the step of:
locking, by a locking device of the baggage cart, a door of the compartment in response to a security inspection starting signal.

17. The security inspection method of claim 13 , further comprising the step of:
inspecting, by the scanning device, a plurality of baggage carts simultaneously, if the plurality of baggage carts pass through the scanning channel in parallel.
