Abstract

An elevator control system, an elevator system including the elevator control system, and a method for controlling an elevator. An elevator control system includes: one or more call-out units, each of which is provided at a corresponding elevator landing station; a control unit configured to perform the following operations: receiving a call request message from one or more of the call-out units, the call request message includes, in addition to an identification of a departure floor, at least one of: an identification of a call requester and a set of elevator resource demand features associated with the call requester; and generating a dispatching command for an elevator car in response to the received call request message.

First claim

What is claimed is:

1 . An elevator control system, comprising:
a plurality of call-out units, each of which is provided at a corresponding elevator landing station; a control unit configured to perform the following operations: receiving a call request message from one or more of the call-out units, wherein the call request message comprises, in addition to an identification of a departure floor, at least one of: an identification of a call requester and a set of elevator resource demand features associated with the call requester; and generating a dispatching command for an elevator car in response to the received call request message.

2 . The elevator control system of claim 1 , wherein the call requester comprises a passenger and device, the call-out unit is configured to: receive a user identity identification or device identification from a mobile terminal or device via a wireless channel, and send to the control unit a floor identification corresponding to the call-out unit and the received user identity identification or device identification.

3 . The elevator control system of claim 1 , wherein the set of elevator resource demand features comprises features in at least one of the following aspects: size of space occupied by the call requester, weight of the call requester, priority level of the call requester to take an elevator, restrictive requirements for the call requester to take the elevator with other call requesters, and restrictive requirements for the call requester to take the elevator alone.

4 . The elevator control system of claim 3 , wherein the size of space occupied by the call requester is represented by discrete values, and each discrete value corresponds to a space range.

5 . The elevator control system of claim 1 , wherein the call request message comprises the identification of the departure floor and the identification of the call requester, the operation of generating the dispatching command for the elevator car is implemented in the following manner:
determining the set of elevator resource demand features corresponding to the identification of the call requester; determining, based on the determined set of elevator resource demand features, an elevator car matching the call request message; generating a dispatching command instructing the matched elevator car to travel to the departure floor.

6 . The elevator control system of claim 5 , wherein the control unit comprises local memory storing the set of elevator resource demand features of the call requester, and the control unit obtains the set of elevator resource demand features corresponding to the identification of the call requester by accessing the local memory.

7 . The elevator control system of claim 5 , wherein the set of elevator resource demand features of the call requester is stored in cloud, and the control unit obtains the set of elevator resource demand features corresponding to the identification of the call requester by accessing the cloud.

8 . The elevator control system of claim 5 , wherein the set of elevator resource demand features of the call requester is stored in local memory of the control unit and in cloud, and the control unit first obtains the set of elevator resource demand features corresponding to the identification of the call requester by accessing the local memory, and obtains the set of elevator resource demand features corresponding to the identification of the call requester by accessing the cloud when the obtaining fails.

9 . The elevator control system of claim 3 , wherein the call request message comprises the identification of the departure floor and the set of elevator resource demand features, the operation of generating the dispatching command for the elevator car is implemented in the following manner:
determining an elevator car matching the call request message based on the set of elevator resource demand features in the call request message; generating a dispatching command instructing the matched elevator car to travel to the departure floor.

10 . The elevator control system of claim 9 , wherein the call-out unit is configured to perform the following operations:
obtaining an image near a panel of the call-out unit when the call-out unit receives a user input; extracting a profile of a moving object in the obtained image; determining, based on the extracted profile, a set of elevator resource demand features associated with the call requester.

11 . The elevator control system of claim 1 , wherein the call request message comprises the identification of the departure floor, the identification of the call requester and the set of elevator resource demand features, the control unit is further configured to perform at least one of the following operations:
storing the set of elevator resource demand features corresponding to the identification of the call requester in local memory of the control unit; uploading the set of elevator resource demand features corresponding to the identification of the call requester to cloud.

12 . An elevator system comprising the elevator control system of claim 1 .

13 . A method for controlling an elevator, comprising:
A. generating a call request message by one or more of a plurality of call-out units, wherein each call-out unit is provided at a corresponding elevator landing station, the call request message comprises, in addition to an identification of a departure floor, at least one of: an identification of a call requester and a set of elevator resource demand features associated with the call requester; and B. generating, by a control unit, a dispatching command for an elevator car in response to the call request message.

14 . The method of claim 13 , wherein the call requester comprises a passenger and device, step A comprises:
receiving a user identity identification or device identification from a mobile terminal or device via a wireless channel; sending to the control unit a floor identification corresponding to the call-out unit and the received user identity identification or device identification.

15 . The method of claim 13 , wherein the set of elevator resource demand features comprises features in at least one of the following aspects: size of space occupied by the call requester, weight of the call requester, priority level of the call requester to take an elevator, restrictive requirements for the call requester to take the elevator with other call requesters, and restrictive requirements for the call requester to take the elevator alone.

16 . The method of claim 15 , wherein the size of space occupied by the call requester is represented by discrete values, and each discrete value corresponds to a space range.

17 . The method of claim 13 , wherein the call request message comprises the identification of the departure floor and the identification of the call requester, step B comprises:
determining the set of elevator resource demand features corresponding to the identification of the call requester; determining, based on the determined set of elevator resource demand features, an elevator car matching the call request message; generating a dispatching command instructing the matched elevator car to travel to the departure floor.

18 . The method of claim 17 , wherein the control unit comprises local memory storing the set of elevator resource demand features of the call requester, and the control unit obtains the set of elevator resource demand features corresponding to the identification of the call requester by accessin
