no. 1 Embodiment approach

[0026] figure 1 It is a configuration diagram of an elevator wireless communication system as a first embodiment. In the elevator control system of the present embodiment, the passenger car 20 and the counterweight (counterweight) 21 are installed in the hoistway 10, and are supported by guide rails (not shown) so as to be movable up and down.

[0027] In the upper part of the hoistway, a control unit 30 called a control panel for controlling the entire elevator is provided on the upper part of the hoistway, and a hoist 40 is also installed. At the winch 40 , the winding frame is provided with a main rope 11 that is connected to the passenger car 20 at one end and to a counterweight 21 at the other end.

[0028] Based on the control of the control unit 30, the winch 40 is driven, and the passenger car 20 and the counterweight 21 connected to both ends of the main rope 11 move up and down in directions opposite to each other. The control unit 30 is connected to the pulse gene...

no. 2 Embodiment approach

[0071] Figure 8It is a diagram of the elevator wireless communication system when the wireless relay device fails in the second embodiment. The elevator wireless communication system of this embodiment transmits the operation|movement confirmation signal 71 from the control part 30 to each wireless relay apparatus 60 via the transmission path 80 (60a-60c).

[0072] When each wireless relay device 60 receives the operation confirmation signal 71, it transmits a response signal 72 to the control unit 30 (72a to 72c). Let the response signal transmitted by the wireless relay device 60a be 72a, the response signal transmitted by the wireless relay device 60b be 72b, and the response signal transmitted by the wireless relay device 60c be 72c. exist Figure 8 In , since the wireless relay device 60b has failed, 72b uses the response signal as a dotted arrow.

[0073] When the wireless relay device 60b fails, the response signal 72b cannot be transmitted, so the control unit 30 c...

no. 3 Embodiment approach

[0085] In the third embodiment, the comparison unit 34 performs matching by using the position information of the passenger car 20 obtained by the pulse generator 41 of the first embodiment and the presence or absence and signal strength of the response signal 72 of the second embodiment. The determination of whether or not the wireless relay device 60 is faulty is determined.

[0086] In the present embodiment, the position information of the passenger car 20 obtained by the pulse generator 41 in the first embodiment and the signal strength from the wireless device 22 are judged by the comparison unit 34 (judgment of the first matching), Determination of the position information of the passenger car 20 obtained by the generator 41 and the signal strength of the response signal 72 (judgment of the second compatibility) enables accurate failure determination of the elevator wireless system.

[0087] In this embodiment, when both the 1st compatibility and the 2nd compatibility a...

Abstract

The present invention provides an elevator wireless communication system for performing continued operation of an elevator system by discriminating a failure of a wireless relay device in a shaft. Provided with: a plurality of wireless relay devices disposed along a traveling direction of the passenger car of the elevator and receiving signals; and a control unit having: a signal determining unitthat determines presence or absence or strength of a signal received by the wireless relay devices; a failure determining unit that determines a failure in at least one of the plurality of wireless relay devices based on the determination result of the determining unit; a receiving area control unit that expands a receiving area of a wireless relay device adjacent to the wireless relay device determined to be faulty in a case where the failure determining unit determines one of the plurality of wireless relay devices as a failure.

Description

technical field [0001] Embodiments of the present invention relate to an elevator wireless communication system. Background technique [0002] Conventionally, the elevator control device (control unit) drives the hoist and controls the lifting operation of the passenger car in the hoistway, and controls the opening and closing of the car door of the passenger car leveling at a predetermined elevator hall. The control signals etc. are transmitted to the passenger car. In transmission of this control signal, it transmits using the tail cord which connects a control part and a passenger car. [0003] In the case of a long-distance hoistway in which the passenger car of the elevator travels, the above-mentioned lead wires need to be lengthened, so the weight of the lead wires increases. Driving force increased. [0004] Therefore, a structure has been proposed in which a control signal between an elevator control device and a passenger car is transmitted wirelessly without us...
