Abstract

Provided is a communication system and a communication method for use in an elevator system, which belong to the field of elevator intelligent control technologies. The communication system of the present invention comprises: a first bluetooth module mounted in an elevator landing area of the elevator system and a second bluetooth module mounted in an elevator car of the elevator system. The communication system and the communication method of the present invention can realize that a passenger completes an elevator calling operation in a completely hand-free mode, which is easy to realize and is low in cost.

First claim

What is claimed is:

1. A communication system for use in an elevator system, wherein the communication system comprises:
a first bluetooth module for broadcasting a first bluetooth signal and automatically establishing a first bluetooth connection with a personal mobile terminal based on the first bluetooth signal, and receiving an elevator calling request command regarding an elevator calling direction sent from the personal mobile terminal when establishing the first bluetooth connection;
a second bluetooth module for broadcasting a second bluetooth signal and automatically establishing a second bluetooth connection with the personal mobile terminal based on the second bluetooth signal, and receiving a target floor registration command sent from the personal mobile terminal when establishing the second bluetooth connection;
wherein the first bluetooth module is mounted in an elevator landing area of the elevator system, and the second bluetooth module is mounted in an elevator car of the elevator system;
wherein the first bluetooth module is further configured to return a first confirmation message to the personal mobile terminal after receiving the elevator calling request command;
wherein the personal mobile terminal is further configured to actively disconnect the first bluetooth connection based on the first confirmation message received;
wherein the second bluetooth module is further configured to return a second confirmation message to the personal mobile terminal after receiving the target floor registration command;
wherein the personal mobile terminal is further configured to actively disconnect the second bluetooth connection based on the second confirmation message received; and
wherein the first confirmation message indicates that the elevator calling request command is successfully accepted by the elevator system, and the second confirmation message indicates that the target floor registration command is successfully accepted by the elevator system.

2. The communication system as claimed in claim 1 , characterized in that the personal mobile terminal is configured to automatically establish the first bluetooth connection or the second bluetooth connection with only one of the first bluetooth module and the second bluetooth module at a certain moment.

3. The communication system as claimed in claim 2 , characterized in that the personal mobile terminal is further configured to automatically establish the second bluetooth connection with the second bluetooth module after the first bluetooth connection previously established thereby with the first bluetooth module is disconnected.

4. The communication system as claimed in claim 2 , characterized in that the personal mobile terminal is further configured to automatically establish the first bluetooth connection when a signal strength of the first bluetooth signal received thereby changes from relatively weak to equal to or greater than a first strength value; and/or
automatically establish the second bluetooth connection when a signal strength of the second bluetooth signal received thereby changes from relatively weak to equal to or greater than a second strength value.

5. The communication system as claimed in claim 2 , characterized in that the personal mobile terminal is further configured to substantially determine a distance from the personal mobile terminal to the first bluetooth module according to a signal strength of the first bluetooth signal received thereby, and automatically establish the first bluetooth connection when the distance is smaller than or equal to a first distance threshold value; and/or
substantially determine a distance from the personal mobile terminal to the second bluetooth module according to a signal strength of the second bluetooth signal received thereby, and automatically establish the second bluetooth connection when the distance is smaller than or equal to a second distance threshold value.

6. The communication system as claimed in claim 5 , characterized in that the second distance threshold value is equal to or greater than 0.7 meter and is smaller than or equal to 1 meter, and the first distance threshold value is greater than the second distance threshold value.

7. The communication system as claimed in claim 4 , characterized in that the personal mobile terminal is further configured to automatically wake up from a sleep mode when the signal strength of the first bluetooth signal received thereby changes from relatively weak to equal to or greater than the first strength value.

8. The communication system as claimed in claim 4 , characterized in that the personal mobile terminal is further configured to automatically wake up from a sleep mode when the distance therefrom to the first bluetooth module is smaller than or equal to the first distance threshold value.

9. The communication system as claimed in claim 1 , characterized in that the first bluetooth module is configured to respectively establish the first bluetooth connection with a plurality of personal mobile terminals in sequence; and/or
the second bluetooth module is configured to respectively establish the second bluetooth connection with a plurality of personal mobile terminals in sequence.

10. The communication system as claimed in claim 1 , characterized in that the personal mobile terminal is further configured to automatically enter a sleep mode after the second bluetooth connection is disconnected.

11. The communication system as claimed in claim 1 , characterized in that the first bluetooth signal and/or the second bluetooth signal comprise(s) a wake-up signal for waking up the personal mobile terminal, and the personal mobile terminal is further configured to automatically wake up from the sleep mode after receiving the wake-up signal.

12. The communication system as claimed in claim 1 , characterized in that the first bluetooth signal comprises a data signal that reflects a universally unique identifier of the first bluetooth module and/or first floor location information about where the first bluetooth module is located; and/or
the second bluetooth signal comprises a data signal that reflects a universally unique identifier of the second bluetooth module and/or second floor location information about where the second bluetooth module is located.

13. The communication system as claimed in claim 1 , characterized in that the first bluetooth module and/or the second bluetooth module are/is bluetooth low energy modules/a bluetooth low energy module.

14. The communication system as claimed in claim 1 , characterized in that the first bluetooth module is integratedly arranged in an elevator calling control panel of the elevator system, wherein a first communication connection is established between the elevator calling control panel and an elevator controller of the elevator system, and a second communication connection is established between the first bluetooth module and the elevator calling control panel; and/or
the second bluetooth module is integratedly arranged in a floor registration control panel of the elevator system, wherein a third communication connection is established between the floor registration control panel and the elevator controller of the elevator system, and a fourth communication connection is established between the second bluetooth module and the floor registration control panel.

15. The communication system as claimed in claim 14 , characterized in that the first communication connection and the third communication connection are remote serial connections, and the second communication connection and the fourth communica
