Embodiment 1

[0033] Embodiment 1 is an embodiment of a multi-car elevator system and a route determination method in which a control panel as a control device communicates with a plurality of cars wirelessly. That is, Embodiment 1 is an embodiment of a multi-car elevator system and its route determination method. The lowermost antenna is used to control the lift of the car, and each car has: a pair of antennas, which are installed above and below the car; the position detection part of the car detects the position of the car in the elevator passage. The inter-car distance detection unit detects the inter-car distance between the car and other adjacent cars; the communication direction selection unit is based on the detection results of the car position detection unit and the inter-car distance detection unit , to select the transmission path of the car; the antenna selection unit selects one of a pair of antennas according to the selection result of the communication direction selection un...

Embodiment 2

[0048] Embodiment 2 is to wirelessly perform mutual communication between the control panel as the control device and a plurality of cars, by using the position of the own car, the distance between the cars, and the signal received by the wireless signal transceiver unit to create and store An embodiment of a circular multi-car elevator system and a route determination method for selecting communication directions using a distance table between cars. That is, the car is an embodiment of the following structure: it is further equipped with an inter-car distance table based on the output of the own car position detection unit and the inter-car distance detection unit and the information received by the wireless signal transceiver unit. The position information of other cars is generated, and the communication direction selection unit selects the transmission route of the own car using the generated inter-car distance table.

Embodiment 3

[0055] Embodiment 3 is an embodiment of a multi-car elevator system and a route determination method in which the distance between cars and the number of hops are weighted and added to select a transport route. That is, it is an embodiment of the structure in which the communication direction selection unit obtains the distance between cars stored in the distance table between cars, and performs a calculation on the distance between cars of other cars that exist between the own car and the uppermost part. Weighted addition. In addition, weighted addition is performed on the distances between other cars that exist between the own car and the bottom. Based on the result of weighted addition, the transmission path of the own car and the communication direction are selected. The selection unit has a structure in which a weighted comparison is made between the number of hops based on the number of other cars existing between the own car and the uppermost part and between the own car...

Abstract

Provided is a multicar elevator system in which a plurality of cars is installed in an elevator shaft, wherein stable wireless communication can be performed between the control device and the plurality of cars. The plurality of cars comprises a car position detection unit 113 and a communication direction selection unit 115 that selects the transmission route direction on the basis of detection results of an inter-car distance detection unit 114. The communication direction selection unit 115 selects the transmission route direction on the basis of the inter-car distance with an adjacent car.A wireless signal transceiver 116 and an antenna selection unit 117 select one of a pair of antennas 111, 112 to be used for wireless communication according to the selection results of the communication direction selection unit 115 and perform transmission and reception of necessary information between the control panel and the other car.

Description

technical field [0001] The present invention relates to a multi-car elevator system, in particular to a path determination technique using wireless communication. Background technique [0002] In recent years, elevators such as elevators have pursued the improvement of transportation capacity and convenience in buildings, and elevators that can move vertically and horizontally (MULTI from Thyssen Corporation) and double-sided elevators that use the main rope as a secondary conductor and are driven by linear motors are being developed. Development of van-type circulation multi-car elevator system, etc. The construction of super high-rise buildings and large buildings is increasing, and in such large-scale buildings, a multi-car elevator system with a high conveyance capacity per unit area is useful. In such a multi-car elevator system, since there are a plurality of cars in the space of the hoistway through which the elevator cars (hereinafter referred to as cars) pass, the ...
