Abstract

A system and a method for detecting passenger movement, an elevator-calling control method, a readable storage medium and an elevator system are provided by the present disclosure. The system for detecting passenger movement includes: a Bluetooth matrix installed in an elevator landing area, the Bluetooth matrix including at least three Bluetooth modules, and each of the Bluetooth modules being configured to broadcast a Bluetooth signal to the elevator landing area respectively; wherein the system for detecting passenger movement acquires location information of a passenger carrying a personal mobile terminal by using Bluetooth signals broadcast by at least three Bluetooth modules; the system for detecting passenger movement further includes: a movement prediction unit configured to fit a movement trajectory of the passenger in the elevator landing area based on multiple sets of the location information, and predict the movement trajectory to be a calling trajectory or a non-calling trajectory.

First claim

What is claimed is:

1. A system for detecting passenger movement, comprising:
a Bluetooth matrix installed in an elevator landing area, the Bluetooth matrix comprising at least three Bluetooth modules, and each of the Bluetooth modules being configured to broadcast a Bluetooth signal to the elevator landing area respectively;
wherein the system for detecting passenger movement acquires location information of a passenger carrying a personal mobile terminal by using Bluetooth signals broadcast by at least three Bluetooth modules;
the system for detecting passenger movement further comprises: a movement prediction unit configured to fit a movement trajectory of the passenger in the elevator landing area based on multiple sets of the location information, and predict the movement trajectory to be a calling trajectory or a non-calling trajectory.

2. The system for detecting passenger movement according to claim 1 , wherein the movement prediction unit is configured to predict the movement trajectory to be the calling trajectory in a case that an end point of the movement trajectory falls within a set calling interval; and predict the movement trajectory to be the non-calling trajectory in a case that the end point of the movement trajectory does not fall within the set calling interval.

3. The system for detecting passenger movement according to claim 2 , wherein the set calling interval comprises each elevator door and a first preset length on one side or both sides of the elevator door.

4. The system for detecting passenger movement according to claim 1 , wherein the movement prediction unit is configured to start performing the prediction action when the location information of the passenger is within a set calling range.

5. The system for detecting passenger movement according to claim 4 , wherein the set calling range is within a first preset radius centering at each elevator car.

6. The system for detecting passenger movement according to claim 1 , wherein the Bluetooth modules in the Bluetooth matrix are equally spaced apart.

7. The system for detecting passenger movement according to claim 1 , wherein the Bluetooth matrix is arranged in a form of rectangular or triangular grids, wherein the Bluetooth modules are located at respective intersections of the grids.

8. The system for detecting passenger movement according to claim 1 , wherein the Bluetooth modules in the Bluetooth matrix are spaced apart from each other by 4 to 8 meters.

9. The system for detecting passenger movement according to claim 1 , wherein the Bluetooth signal of the Bluetooth module has a broadcast interval of 0.02 second to 1 second.

10. An elevator system, comprising a plurality of elevator cars, an elevator controller, and a movement detection system; the movement detection system comprises:
a Bluetooth matrix installed in an elevator landing area, the Bluetooth matrix comprising at least three Bluetooth modules, and each of the Bluetooth modules being configured to broadcast a Bluetooth signal to the elevator landing area respectively;

11. The elevator system according claim 10 , wherein the elevator controller is further configured to receive a calling request command transmitted from the personal mobile terminal, and assign an elevator corresponding to the predicted calling trajectory to go to a corresponding floor, based on the predicted calling trajectory.

12. The elevator system according claim 10 , wherein the movement prediction unit is configured to predict the movement trajectory to be the calling trajectory in a case that an end point of the movement trajectory falls within a set calling interval; and predict the movement trajectory to be the non-calling trajectory in a case that the end point of the movement trajectory does not fall within the set calling interval.

13. The elevator system according claim 12 , wherein the set calling interval comprises each elevator door and a first preset length on one side or both sides of the elevator door.

14. The elevator system according claim 10 , wherein the movement prediction unit is configured to start performing the prediction action when the location information of the passenger is within a set calling range.

15. The elevator system according claim 14 , wherein the set calling range is within a first preset radius centering at each elevator car.

16. The elevator system according to claim 11 , wherein the Bluetooth modules in the Bluetooth matrix are equally spaced apart.

17. The elevator system according to claim 11 , wherein the Bluetooth matrix is arranged in a form of rectangular or triangular grids, wherein the Bluetooth modules are located at respective intersections of the grids.

18. A method for detecting passenger movement, comprising:
