Abstract

An automatic elevator call system includes: a wireless signal apparatus installed in an elevator landing zone of an elevator system and broadcasting a corresponding wireless signal around; a counting unit configured to count, after an elevator call request corresponding to an identity of the personal mobile terminal is sent or received, the number of times the elevator call request corresponding to the identity is made within a predetermined time period; and an abnormal elevator call request judgment unit configured to judge, based on a comparison result between the number of times the elevator call request is made and a predetermined threshold, whether the elevator call request corresponding to the identity is a normal elevator call request operation. The present invention can effectively determine an intentional or unintentional abnormal elevator call request operation of a passenger.

First claim

What is claimed is:

1. An automatic elevator call system, comprising:
a wireless signal apparatus installed in an elevator landing zone of an elevator system and broadcasting a corresponding wireless signal around;
wherein the automatic elevator call system detects the wireless signal through a personal mobile terminal, and is capable of sending an elevator call request to the wireless signal apparatus automatically; and
the automatic elevator call system further comprises:
a counting unit configured to count, after an elevator call request corresponding to an identity of the personal mobile terminal is sent or received, the number of times the elevator call request corresponding to the identity is made within a predetermined time period; and
an abnormal elevator call request judgment unit configured to judge, based on a comparison result between the number of times the elevator call request is made and a predetermined threshold, whether the elevator call request corresponding to the identity is a normal elevator call request operation.

2. The automatic elevator call system according to claim 1 , wherein the abnormal elevator call request judgment unit is further configured to determine the elevator call request corresponding to the identity as an abnormal elevator call request operation when the number of times the elevator call request is made is greater than or equal to the predetermined threshold, and to determine the elevator call request corresponding to the identity as a normal elevator call request operation when the number of times the elevator call request is made is less than the predetermined threshold.

3. The automatic elevator call system according to claim 1 , wherein the predetermined time period is 30 seconds to 1 minute.

4. The automatic elevator call system according to claim 1 , wherein the predetermined threshold is greater than or equal to 3 times and less than or equal to 10 times.

5. The automatic elevator call system according to claim 1 , wherein the counting unit and the abnormal elevator call request judgment unit are disposed in the personal mobile terminal.

6. The automatic elevator call system according to claim 5 , wherein the automatic elevator call system further stops, through a sending stop unit in the personal mobile terminal, sending the elevator call request corresponding to the identity when the elevator call request corresponding to the identity is determined as an abnormal elevator call request.

7. The automatic elevator call system according to claim 1 , wherein the counting unit and the abnormal elevator call request judgment unit are disposed in the wireless signal apparatus.

8. The automatic elevator call system according to claim 7 , wherein the wireless signal apparatus is further provided with a receiving stop unit configured to stop receiving the elevator call request corresponding to the identity when the elevator call request corresponding to the identity is determined as an abnormal elevator call request.

9. The automatic elevator call system according to claim 7 , wherein the wireless signal apparatus is further configured to cancel the elevator call request when the elevator call request corresponding to the identity is determined as an abnormal elevator call request.

10. The automatic elevator call system according to claim 7 , wherein the automatic elevator call system further sends an elevator call request comprising a corresponding identity to the wireless signal apparatus automatically through the personal mobile terminal.

11. The automatic elevator call system according to claim 1 , wherein the elevator call request can be implemented by a manual operation of a passenger carrying the personal mobile terminal.

12. The automatic elevator call system according to claim 1 , wherein the wireless signal apparatus is a Bluetooth module/Bluetooth Low Energy (BLE) module, and the wireless signal is a Bluetooth signal/BLE signal.

13. A method for determining an abnormal elevator call request of an automatic elevator call system, comprising steps of:
counting, after an elevator call request corresponding to an identity of a personal mobile terminal is sent or received, the number of times the elevator call request corresponding to the identity is made within a predetermined time period; and
judging, based on a comparison result between the number of times the elevator call request is made and a predetermined threshold, whether the elevator call request corresponding to the identity is a normal elevator call request operation;
wherein in the judging step, the elevator call request corresponding to the identity is determined as an abnormal elevator call request operation if the number of times the elevator call request is made is greater than or equal to the predetermined threshold, and
the elevator call request corresponding to the identity is determined as a normal elevator call request operation if the number of times the elevator call request is made is less than the predetermined threshold.

14. The method according to claim 13 , wherein the predetermined time period is 30 seconds to 1 minute.

15. The method according to claim 13 , wherein the predetermined threshold is greater than or equal to 3 times and less than or equal to 10 times.

16. The method according to claim 13 , further comprising a step of:
stopping sending or receiving the elevator call request corresponding to the identity when the elevator call request corresponding to the identity is determined as an abnormal elevator call request operation.

17. The method according to claim 16 , further comprising a step of:
cancelling the elevator call request when the elevator call request corresponding to the identity is determined as an abnormal elevator call request operation.

18. The method according to claim 16 , further comprising a step of: sending an elevator call request comprising a corresponding identity to the wireless signal apparatus automatically.

19. The method according to claim 13 , further comprising steps of:
broadcasting a corresponding wireless signal through a wireless signal apparatus installed in an elevator landing zone of an elevator system; and
detecting the wireless signal through a personal mobile terminal and sending an elevator call request to the wireless signal apparatus automatically.

20. A wireless signal apparatus, wherein the wireless signal apparatus is installed in an elevator landing zone of an elevator system and broadcasts a corresponding wireless signal around, and is capable of receiving, based on the wireless signal, an elevator call request from a personal mobile terminal that detects the wireless signal; wherein the wireless signal apparatus comprises:
a counting unit configured to count, after an elevator call request corresponding to an identity of a personal mobile terminal is received, the number of times the elevator call request corresponding to the identity is made within a predetermined time period; and
an abnormal elevator call request judgment unit configured to judge, based on a comparison result between the number of times the elevator call request is made and a predetermined threshold, whether the elevator call request corresponding to the identity is a normal elevator call request operation.

21. The wireless signal apparatus according to claim 20 , wherein the abnormal elevator call request judgment unit is further configured to: determine the elevator call request corresponding to the identity as an abnormal elevator call
