Embodiment approach 1

[0034] figure 1 It is a side view showing main parts of an elevator provided with the control device in Embodiment 1 of the present invention, figure 2 It is a front view showing main parts of an elevator provided with a control device in Embodiment 1 of the present invention, image 3 It shows when the elevator doors are fully closed figure 2 A-A direction view.

[0035] exist Figure 1 ~ Figure 3 Among them, 1 is an elevator hall provided on each floor of the building, 2 is an elevator shaft, and 3 is an elevator car that ascends and descends in the shaft 2 . which is, figure 1 It is equivalent to a diagram of the state when the car 3 stops at the hall 1 of the predetermined floor when viewed from the side, figure 2 This corresponds to a view of the car 3 viewed from the landing 1 side.

[0036] A door device 4 is provided at a portion of the elevator car 3 facing the landing 1 . The door device 4 includes, for example, a car door that opens and closes a doorway fo...

Embodiment approach 2

[0073] Figure 7 It is a figure for demonstrating the function of the control apparatus of the elevator in Embodiment 2 of this invention.

[0074] exist Figure 7 In the connecting device 28 shown, when the car door and the hall door are fully closed, a slight gap is formed between each clamping plate 29 and the roller 30 . Therefore, when the car 3 stops at the landing 1 and starts to open the door, during the period before one clamping plate 29 moves to the B direction (door opening direction) and contacts the roller 30, only the car door performs the door opening action, and the landing door Do not open the door.

[0075] In this way, when the connection device 28 has a predetermined structure in which the door opening operation of the landing door from the fully closed state is delayed compared with the opening operation of the car door, by appropriately setting the operation position of the door switch 17 and the above-mentioned predetermined width , it is possible to...

Embodiment approach 3

[0081] Figure 8 It is a flowchart showing the operation of the elevator control device in Embodiment 3 of the present invention. In this embodiment, a case will be described in which the timing of failure determination of the door switch 17 by the failure determination means 34 is determined based on the operating state of the door switch 27 .

[0082] Figure 8 Shown S301~S304 and Figure 5 The operations shown in S101 to S104 are basically the same, and thus detailed description thereof will be omitted.

[0083] When the door opening operation is started by the door opening and closing control unit 33 after reaching the diagnosis floor (S304), the self-diagnosis device 31 determines whether the landing door has moved to the operating position of the door switch 27 (S305). In addition, when the boarding point door moves to the operating position of the door switch 27, the door switch 27 is switched from ON to OFF. Therefore, in the self-diagnosis device 31, the door open...

Abstract

Provided is a control device of an elevator which positively prevents users from boarding a car by mistake during the failure diagnosis of a door switch and ensures that the surrounding people do not mistake the action during the failure diagnosis for a failure of the elevator. During a self-diagnosis of a door switch, the elevator door is caused to open beyond an action position of the door switch and the door is caused to close without causing the door to open to a width which is not less than a prescribed specified width through which an elevator user cannot pass. A determination is made as to the existence or nonexistence of a failure of the door switch on the basis of the action condition of the door switch occurring when such door opening and closing actions are carried out.

Description

technical field [0001] The present invention relates to a control device for fault diagnosis of door switches of elevators. Background technique [0002] In recent years, with the high rise of buildings, elevators have played an increasingly important role as a means of transportation for vertical movement. In high-rise buildings with more than dozens of floors, it is actually very difficult to move to each floor only by stairs. For this reason, especially in elevators in high-rise buildings, it is particularly important to perform fault diagnosis of equipment units before they cannot be started due to faults to find faults as early as possible. [0003] Elevators have door switches that detect the closing of doors (car doors and landing doors). The door switch operates extremely frequently and must stop the elevator in the event of a malfunction. For this reason, in the elevator, it is necessary to carry out the fault diagnosis of the door switch at ordinary times in ord...
