Abstract

The present disclosure relates to a train identification system and method, and a train safety inspection system and method. The train identification system includes: a remote detection component, configured to acquire overall feature information of an inspected train through remote monitoring; and an identification device, configured to determine at least one of a type and a traveling situation of the inspected train according to the acquired overall feature information.

First claim

What is claimed is:

1. A train identification system, comprising:
a remote detection component, configured to acquire overall feature information of an inspected train through remote monitoring; and
an identification device, configured to determine that at least one of a type of the inspected train and a traveling situation of the inspected train according to the acquired overall feature information,
wherein the remote detection component comprises one or more cameras, configured to shoot video information of the inspected train;
the one or more cameras comprise one camera, a video shot by the camera being divided into different areas to correspond to different tracks; or
the one or more cameras comprise a plurality of cameras, the plurality of cameras being configured to shoot different tracks respectively.

2. The train identification system according to claim 1 , wherein
the type of the inspected train comprises at least one of a locomotive, a freight train, a passenger train and an engineering train; or
the traveling situation of the inspected train comprises at least one of: whether the inspected train is arriving, a traveling direction, a traveling route and a traveling speed of the inspected train.

3. The train identification system according to claim 1 , wherein the one or more cameras comprise a plurality of cameras, the plurality of cameras each having various focal distances and being respectively configured to shoot when the inspected train is located in different distance ranges.

4. The train identification system according to claim 1 , wherein at least one of a shooting angle, installation height and focal distance of the one or more cameras are adjustable.

5. A train safety inspection method, comprising:
acquiring overall feature information of an inspected train through remote monitoring by a remote detection component;
determining that at least one of a type of the inspected train and a traveling situation of the inspected train according to the acquired overall feature information by an identification device; and
controlling a working state of an inspection equipment according to a determinationof at least one of the type and the traveling situation of the inspected train;
wherein the remote detection component comprises one or more cameras, configured to shoot video information of the inspected train;
the one or more cameras comprise one camera, a video shot by the camera being divided into different areas to correspond to different tracks; or
the one or more cameras comprise a plurality of cameras, the plurality of cameras being configured to shoot different tracks respectively.

6. The train safety inspection method according to claim 5 , wherein controlling the working state of the inspection equipment according to the determination of at least one of the type and the traveling situation of the inspected train comprises:
judging whether there is a freight train carriage in the inspected train when judging that the inspected train is coming, if yes, turning on the inspection equipment for preparation; if no, the inspection equipment is kept in a closed state.

7. The train safety inspection method according to claim 5 , wherein controlling the working state of the inspection equipment according to the determination that at least one of the type and the traveling situation of the inspected train comprises:
determining the type of the inspected train passing through the inspection equipment when the inspection equipment is turned on, enabling the inspection equipment to emit rays for inspection if a freight train carriage passes through the inspection equipment, and enabling the inspection equipment to stop emitting rays or reduce an emission dosage of the rays if a carriage of a locomotive or passenger train passes through the inspection equipment.

8. The train safety inspection method according to claim 5 , wherein controlling the working state of the inspection equipment according to the determination that at least one of the type and the traveling situation of the inspected train comprises:
enabling the inspection equipment to stop emitting rays or reduce an emission dosage of the rays when a traveling speed of the inspected train is reduced to a preset value or the inspected train stops.

9. The train safety inspection method according to claim 5 , further comprising:
adjusting a scanning frequency of the inspection equipment to be matched with a traveling speed of the inspected train.

10. The train safety inspection method according to claim 5 , wherein judging at least one of the type and the traveling situation of the inspected train according to the acquired overall feature information by the identification device comprises: extracting a feature parameter of the inspected train from the acquired overall feature information, to determine a traveling speed of the inspected train by the identification device;
wherein extracting a feature parameter of the inspected train from the acquired overall feature information, to determine the traveling speed of the inspected train by the identification device comprises:
selecting a first position and a second position along a direction of the inspected train from far to near within a field of view of a camera;
acquiring a frame number and a required time of the inspected train from the first position to the second position in a video, to acquire a frame rate of the inspected train from the first position to the second position in the video; and
comparing the frame rate of the inspected train with the frame rate of the inspected train at a preset traveling speed, to acquire the traveling speed of the inspected train.

11. A train safety inspection system, comprising:
inspection equipment, configured to perform safety inspection on an inspected train;
a train identification system, arranged in an area adjacent to the inspection equipment, wherein the train identification system comprises a remote detection component and an identification device, the remote detection component is configured to acquire overall feature information of an inspected train throgh remote monitoring, the identification device is configured to determine that at least one of a type of the inspected train and a traveling situation of the inspected train according to the acquired overall feature information; and
a radiation control device, configured to control a working state of the inspection equipment according to at least one of the type and the traveling situation of the inspected train determined by the identification device;
wherein the remote detection component comprises one or more cameras, configured to shoot video information of the inspected train;
the one or more cameras comprise one camera, a video shot by the camera being divided into different areas to correspond to different tracks; or
the one or more cameras comprise a plurality of cameras, the plurality of cameras being configured to shoot different tracks respectively.

12. The train safety inspection system according to claim 11 , wherein the radiation control device is configured to turn on the inspection equipment for preparation when the identification device determines that presence of a freight train carriage in the coming inspected train, and keep the inspection equipment in a closed state under the absence of the freight train carriage.

13. The train safety inspection system according to claim 11 , wherein the radiation control device is configured to enable the inspection equipment to emit rays when the identification device determines that a freight train carriage passes through the inspection equipment, and enable the
