Abstract

A control system for elevators includes a capture apparatus, a processor and a storage apparatus. The capture apparatus captures images of each floor. The processor performs human detection on images of each floor to calculate the number of waiting passengers of each floor. The processor further calculates waiting time of each floor. The processor calculates weight of each floor based on the number of the waiting passengers and waiting time, and controls the elevator to the floor with maximum weight.

Claims

1. A control system for an elevator, comprising:

a capture apparatus capturing images of each floor;

a processor coupled to the capture apparatus; and

a storage apparatus coupled to the processor and storing a plurality of programs to be executed by the processor to perform certain functions, the storage apparatus comprising a plurality of units configured to be executed by the processor, the units comprising;

a detecting unit configured to perform human detection on images of each floor to determine whether the images of each floor contains passengers; and

a processing unit configured to calculate the number of passengers of each floor, in response to at least one passenger detecting within the images of corresponding floor, and calculating waiting time of each floor beginning at the time a first passenger being detected within the images of corresponding floor;

wherein the processing unit is configured to calculate weight of the passengers at each floor based on the number of passengers and waiting time and control the elevator to the floor corresponding to the maximum weight.

2. The control system of claim 1, wherein the processing unit determines whether a first direction that the elevator running to the floor corresponding to the maximum weight from the current floor is the same as a second direction that the waiting passenger calls on the maximum weight floor;

when the first direction is different from the second direction, the processing unit controls the elevator to the maximum weight floor.

3. The control system of claim 2, wherein when the first and second directions are the same, the processing unit determines whether a third direction that the waiting passengers call between the current floor and the maximum floor is the same as the first and second directions;

when the third direct is the same as the first direction, the processing unit controls the elevator to stop the floors that the waiting passengers call in the third direction.

4. The control system of claim 1, wherein the processing unit calculates the weight of each floor based on a floor prior mode, the weight of the floor gains a first predetermined value by adding each floor.

5. The control system of claim 2, wherein the processing unit calculates the weight of each floor based on an ignoring ride mode, the weight of the floor gains a second predetermined value by ignoring each time.

6. The control system of claim 5, wherein the processing unit determines whether a first direction that the elevator running to the floor corresponding to the maximum weight from the current floor is the same as a second direction that the waiting passenger calls on the maximum weight floor;

when the first direction is different from the second direction, the processing unit controls the elevator to the maximum weight floor.

7. The control system of claim 6, wherein when the first and second directions are the same, the processing unit determines whether a third direction that the waiting passengers call between the current floor and the maximum floor is the same as the first and second directions;

when the third direct is the same as the first direction, the processing unit controls the elevator to stop the floors that the waiting passengers call in the third direction.

8. The control system of claim 7, wherein the processing unit determines whether pre-loading weight of passengers are greater than the maximum-loading weight of passengers of the elevator before the elevator running to the maximum weight floor from the current floor, the processing unit controls the elevator to the maximum weight floor in response to the pre-loading passengers greater than the maximum-loading passengers.

9. The control system of claim 8, wherein the processing unit controls the elevator to stop at the floor of the third direction called by the waiting passengers, in response to the pre-loading weight of passengers less than the maximum-loading weight of passengers.

10. A control method of elevators, comprising:

capturing images of each floor;

performing human detection on images of each floor to determines whether the images of each floor contains passengers;

calculating the number of passengers of each floor, in response to at least one passenger detecting within the images of corresponding floor;

calculating waiting time of each floor beginning at the time a first passenger being detected within the images of corresponding floor;

calculating weight of each floor based on the number of passengers and waiting time; and

controlling the elevator to the floor corresponding to the maximum weight.

11. The control method of claim 10, further comprising:

determining whether a first direction that the elevator running to the floor corresponding to the maximum weight from the current floor is the same as a second direction that the waiting passenger calls on the maximum weight floor;

controlling the elevator to the maximum weight floor in response to the first direction being different from the second direction.

12. The control method of claim 11, further comprising:

determining whether a third direction that the waiting passengers call between the current floor and the maximum floor is the same as the first and second directions, in response to the first direction being the same as the second direction;

controlling the elevator to stop the floors that the waiting passengers call in the third direction, in response to the third direct is the same as the first direction.

13. The control method of claim 12, further comprising:

determining whether pre-loading weight of passengers are greater than the maximum-loading weight of passengers of the elevator before the elevator running to the maximum weight floor from the current floor;

controlling the elevator to the floor corresponding to the maximum weight in response to the pre-loading weight of passengers greater than the maximum-loading weight of passengers.

14. The control system of claim 12, further comprising:

controlling the elevator to stop at the floor of the third direction called by the waiting passengers, in response to the pre-loading weight of passengers less than the maximum-loading weight of passengers.

15. The control method of claim 14, further comprising:

calculating the weight of each floor based on a floor prior mode, wherein the weight of the floor gains a first predetermined value by adding each floor.

16. The control method of claim 15, further comprising:

calculating the weight of each floor based on an ignoring ride mode, wherein the weight of the floor gains a second predetermined value by ignoring each time.
