Abstract

The present invention relates to a video analysis system for an energy-consuming building equipment. The video analysis system includes a camera and an image processing unit to monitor people who appear in a target region, and in an actual space where the camera coexists with the energy-consuming building equipment, a height from the camera to a bottom surface of the actual space ranges from 2 to 10 meters. The present invention further relates to an intelligent building management system provided with the video analysis system for the energy-consuming building equipment. With the video analysis system of the present invention, a security system of a building is combined with the energy-consuming building equipment by means of an optimal camera design/arrangement, which can improve the operation efficiency of the whole building significantly and achieve a desirable energy-saving effect.

First claim

What is claimed is:

1. An intelligent building management system, wherein, the intelligent building management system is configured with a video analysis system for an energy-consuming building equipment, the video analysis system comprising a camera and an image processing unit to monitor people who appear in a target region, wherein, in an actual space where the camera coexists with the energy-consuming building equipment,
wherein the intelligent building management system comprises a controller, the controller has a control module and a number of people calculation module to maintain a communication with the image processing unit, when the energy-consuming building equipment is an elevator, the number of people calculation module receives video data from the image processing unit and calculate an actual number of people in the target region, and the control module instructs the elevator to stop at a floor where the actual number of people in the target region is greater than or equal to one.

2. The intelligent building management system of claim 1 , wherein, the energy-consuming building equipment is an elevator, and an angle between a lens of the camera and a horizontal plane ranges from 15 to 90 degrees.

3. The intelligent building management system of claim 1 , wherein, the energy-consuming building equipment is an escalator, a height from the camera to an upper bottom surface of the escalator in the actual space ranges from 2 to 10 meters, and an angle between a lens of the camera and a horizontal plane ranges from 30 to 90 degrees.

4. The intelligent building management system of claim 1 , wherein, the energy-consuming building equipment is an escalator, a height from the camera to a lower bottom surface of the escalator in the actual space ranges from 2 to 10 meters, and an angle between a lens of the camera and a horizontal plane ranges from −60 to 60 degrees.

5. The intelligent building management system of claim 1 , wherein, an area of the target region ranges from 5 to 200 square meters.

6. The intelligent building management system of claim 1 , wherein, the energy-consuming building equipment is an air conditioning system.

7. The intelligent building management system of claim 1 , wherein, when the number of the elevators is more than two, the controller further comprises a crowd density detection module, wherein the crowd density detection module receives the video data from the image processing unit and acquires a density level, and the control module adjusts a sequence of the floors where the elevator stops or the number of the elevators in operation according to the density level.

8. The intelligent building management system of claim 1 , wherein, the control module maintains a communication with an air conditioner control unit of an air conditioning system in the target region, so that the control module instructs an air conditioner in the target region to turn on or turn off or adjusts an air volume of the air conditioner according to the actual number of people.

9. An intelligent building management system, wherein, the intelligent building management system is configured with the video analysis system of claim 1 , the intelligent building management system comprises a controller, the controller has a control module, an abnormal behavior detection module and an alarm module to maintain a communication with the image processing unit, when the energy-consuming building equipment is an escalator, the abnormal behavior detection module receives video data from the image processing unit and detects human behaviors, and if when an abnormal situation going against normal human behaviors occurs, the control module sends an alarm signal to the alarm module.

10. The intelligent building management system of claim 9 , wherein, the abnormal behavior detection module further comprises a tumble detection unit to receive the video data from the image processing unit and detect a human tumble behavior, and when there exists a human tumble behavior, the control module sends an alarm signal to the alarm module.

11. The intelligent building management system of claim 9 , wherein, the abnormal behavior detection module further comprises a congestion detection unit to receive the video data from the image processing unit and detect a congestion level, and when the congestion level exceeds a preset value, the control module sends an alarm signal to the alarm module.

12. The intelligent building management system of claim 9 , wherein, the control module maintains a communication with an air conditioner control unit of an air conditioning system in the target region, and the controller further comprises a number of people calculation module to receive the video data from the image processing unit and calculate an actual number of people in the target region, so that the control module instructs an air conditioner in the target region to turn on or turn off or adjusts an air volume of the air conditioner according to the actual number of people.

13. The intelligent building management system of claim 1 , wherein a height from the camera to a bottom surface of the actual space ranges from 2 to 10 meters.
