Location identification and location recovery of elevator

A location recovery method for an elevator system, wherein the elevator system comprises:

• an elevator car;
• an elevator shaft comprising a plurality of landings;
• and
• an elevator control device configured to at least control a movement of the elevator car within the elevator shaft;
• a location recovery system comprising:
• landing floor information components arranged correspondingly on at least two of the plurality of landings and having floor location information of the corresponding landings;
• a sensing component arranged corresponding to each landing floor information component and coupled to the landing floor information component;
• and
• a trigger component mounted on the elevator car;
• wherein the location recovery method comprises:
• controlling the elevator car to move until it moves to a landing having the sensing component when the elevator control device loses the current location information of the elevator car or has invalid location information, and triggering the sensing component by the trigger component;
• and
• transmitting the floor location information of the landing floor information component coupled correspondingly to the triggered sensing component as the current location information of the elevator car to the elevator control device.

An elevator system comprising:

• an elevator car;
• an elevator shaft comprising a plurality of landings;
• and
• an elevator control device configured to at least control a movement of the elevator car within the elevator shaft;
• a location recognition system comprising:
• a calling component arranged correspondingly on each of the landings;
• a sensing component arranged corresponding to the calling component of each landing and coupled to the calling component;
• and
• a trigger component mounted on the elevator car,
• wherein each of the calling components has floor location information of the corresponding landing, and the sensing component is capable of being triggered by the trigger component to transmit a location recovery signal to enable the corresponding coupled landing floor information component to transmit the floor location information of the calling component to the elevator control device;
• wherein the elevator shaft further comprises a dummy landing without the calling component and the sensing component.

A location recognition method for an elevator system, wherein the elevator system comprises:

• an elevator car;
• an elevator shaft comprising a plurality of landings;
• and
• an elevator control device configured to at least control a movement of the elevator car within the elevator shaft;
• a location recognition system comprising:
• a calling component arranged correspondingly on each of the landings, each of the calling components having floor location information of the corresponding landing;
• a sensing component arranged corresponding to the calling component of each landing and coupled to the calling component;
• and
• a trigger component mounted on the elevator car,
• wherein the location recognition method comprises:
• controlling the elevator car to move until it moves to a landing having the sensing component, and triggering the sensing component by the trigger component;
• and
• transmitting the floor location information of the calling component coupled correspondingly to the triggered sensing component as the current location information of the elevator car to the elevator control device.

An elevator system comprising:

• an elevator car;
• an elevator shaft comprising a dummy landing and a plurality of landings;
• an elevator control device configured to at least control a movement of the elevator car within the elevator shaft;
• and
• a location recovery/recognition system comprising:
• a landing floor information component arranged correspondingly on each of the plurality of landings and having floor location information of the corresponding landing;
• a sensing component arranged corresponding to each landing floor information component and coupled to the landing floor information component;
• and
• a trigger component mounted on the elevator car,
• wherein the dummy landing is not provided with the landing floor information component and the sensing component;
• wherein the sensing component is capable of being triggered by the trigger component to transmit a location recovery signal to enable the corresponding coupled landing floor information component to transmit the floor location information of the landing floor information component to the elevator control device.
