Abstract
A movement detection system for a passenger in the present invention includes: a first Bluetooth module (150) mounted in an elevator landing area; and a movement prediction unit (270) configured to predict, based on Bluetooth movement data, that a movement of a passenger in the elevator landing area is a normal movement or an abnormal movement. The movement detection system and a movement detection method in the present invention can automatically detect an abnormal movement of a passenger, and are especially applicable to an elevator system that completes an elevator call operation without an input operation.
Claims20
A movement detection system for a passenger, comprising:
- a first Bluetooth module mounted in an elevator landing area and configured to broadcast a first Bluetooth signal to the elevator landing area, wherein
- the movement detection system receives the first Bluetooth signal by a personal mobile terminal carried by the passenger, and generates Bluetooth movement data corresponding to a movement of the passenger in the elevator landing area;
- and
- the movement detection system further comprises:
- a movement prediction unit configured to predict, based on the Bluetooth movement data, that the movement of the passenger in the elevator landing area is a normal movement or an abnormal movement;
- wherein the movement detection system further comprises a signal strength determination module and a movement tracking module that are disposed in the personal mobile terminal;
- wherein:
- the signal strength determination module is configured to determine the signal strength of the first Bluetooth signal received by the personal mobile terminal;
- and
- the movement tracking module is configured to track the movement of the passenger in the elevator landing area by means of changes in the determined signal strength of the first Bluetooth signal, and generate the Bluetooth movement data corresponding to the movement.
A movement detection method for a passenger, the method comprising:
- receiving, by a personal mobile terminal carried by the passenger, a first Bluetooth signal broadcasted by a first Bluetooth module mounted in an elevator landing area;
- generating Bluetooth movement data corresponding to a movement of the passenger in the elevator landing area;
- predicting, based on the Bluetooth movement data, that the movement of the passenger in the elevator landing area is a normal movement or an abnormal movement;
- determining the signal strength of the first Bluetooth signal received by the personal mobile terminal;
- tracking the movement of the passenger in the elevator landing area by means of changes in the determined signal strength of the first Bluetooth signal;
- and
- generating the Bluetooth movement data corresponding to the movement.
