Abstract

The present invention relates to automatic elevator call control, and belongs to the field of elevator intelligent control technologies. An automatic elevator call system provided in the present invention calculates duration information from the moment when the personal mobile terminal leaves coverage of the wireless signal to the moment when the personal mobile terminal enters the coverage again, and when the duration information is less than or equal to a preset time threshold, causes the personal mobile terminal to be incapable of automatically sending an elevator call request command in a time period from the moment when the personal mobile terminal enters the coverage again to the moment when the personal mobile terminal leaves the coverage again. The present invention can effectively avoid invalid or abnormal elevator call request operations, and the elevator system achieves high running efficiency.

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 wireless signal apparatus receives an elevator call request command automatically sent by a personal mobile terminal carried by a passenger in the case where the personal mobile terminal senses the wireless signal;
wherein the automatic elevator call system further comprises: a timing circuitry configured to calculate duration information from the moment when the personal mobile terminal leaves coverage of the wireless signal to the moment when the personal mobile terminal enters the coverage again;
an enabling circuitry configured to: when the duration information is less than or equal to a preset time threshold, cause the personal mobile terminal to be incapable of automatically sending the elevator call request command in a time period from the moment when the personal mobile terminal enters the coverage again to the moment when the personal mobile terminal leaves the coverage again; and
an input circuitry disposed in the personal mobile terminal, wherein the input circuitry is configured to input request service information about the elevator call request command.

2. The automatic elevator call system according to claim 1 , wherein the timing circuitry and/or the enabling circuitry are/is disposed in the personal mobile terminal carried by the passenger.

3. The automatic elevator call system according to claim 1 , wherein the enabling circuitry is further configured to: when the duration information is greater than the preset time threshold, cause the personal mobile terminal to be capable of automatically sending the elevator call request command normally in a time period from the moment when the personal mobile terminal enters the coverage again to the moment when the personal mobile terminal leaves the coverage again.

4. The automatic elevator call system according to claim 1 , wherein the time threshold is greater than or equal to 15 seconds and less than or equal to 2 minutes.

5. The automatic elevator call system according to claim 1 , wherein the time threshold is greater than or equal to 30 seconds and less than or equal to 1 minute.

6. The automatic elevator call system according to claim 1 , wherein the automatic elevator call system further comprises a short range communication circuitry disposed in the personal mobile terminal, and the short range communication circuitry is configured to sense the wireless signal and determine whether the personal mobile terminal leaves or enters the coverage.

7. The automatic elevator call system according to claim 6 , wherein the short range communication circuitry is further configured to determine that the personal mobile terminal leaves the coverage in the case where the wireless signal is sensed at first and then not sensed or in the case where signal strength of the sensed wireless signal gradually decreases to approximately 0; and
the short range communication circuitry is further configured to determine that the personal mobile terminal enters the coverage in the case where the wireless signal is not sensed at first and then sensed.

8. The automatic elevator call system according to claim 1 , further comprising an elevator call request command generating circuitry disposed in the personal mobile terminal, wherein the elevator call request command generating circuitry is configured to automatically generate the corresponding elevator call request command when signal strength of the sensed wireless signal is greater than or equal to trigger threshold strength.

9. The automatic elevator call system according to claim 1 , wherein the enabling circuitry is further configured to be capable of automatically sending the elevator call request command only once in a time range from the moment of entering the coverage to the moment of leaving the coverage.

10. 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.

11. An automatic elevator call control method, comprising steps of:
sensing a wireless signal broadcasted by a wireless signal apparatus installed in an elevator landing zone of an elevator system;
calculating duration information from the moment when a personal mobile terminal leaves coverage of the wireless signal to the moment when the personal mobile terminal enters the coverage again;
when the duration information is less than or equal to a preset time threshold, causing the personal mobile terminal to be incapable of automatically sending an elevator call request command in a time period from the moment when the personal mobile terminal enters the coverage again to the moment when the personal mobile terminal leaves the coverage again; and
manually inputting request service information about the elevator call request command.

12. The automatic elevator call control method according to claim 11 , further comprising a step of:
when the duration information is greater than the preset time threshold, causing the personal mobile terminal to be capable of automatically sending the elevator call request command normally in a time period from the moment when the personal mobile terminal enters the coverage again to the moment when the personal mobile terminal leaves the coverage again.

13. The automatic elevator call control method according to claim 11 , further comprising steps of: determining that the personal mobile terminal leaves the coverage in the case where the wireless signal is sensed at first and then not sensed or in the case where signal strength of the sensed wireless signal gradually decreases to approximately 0; and
determining that the personal mobile terminal enters the coverage in the case where the wireless signal is not sensed at first and then sensed.

14. The automatic elevator call control method according to claim 11 , further comprising a step of:
automatically generating the corresponding elevator call request command when signal strength of the sensed wireless signal is greater than or equal to trigger threshold strength.

15. The automatic elevator call control method according to claim 11 , wherein the elevator call request command can be automatically sent only once in a time range from the moment of entering the coverage to the moment of leaving the coverage.

16. A non-transitory computer readable storage medium, storing a computer program, wherein the program can be executed by a processor to implement steps of the automatic elevator call control method according to claim 11 .

17. An elevator system, comprising:
the automatic elevator call system according to claim 1 ; and
an elevator controller configured to control running of one or more elevator cars in the elevator system;
wherein the elevator controller is coupled to the wireless signal apparatus and controls the running of the one or more elevator cars in the elevator system in response to at least the elevator call request command.
