BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
[0015]
FIG. 1 is a diagram illustrating an overall configuration of an elevator management information display device according to an embodiment of the present invention. In the figure, landing panels 5-1, 5-2,... Are the same as the landing panels shown in FIG. 4, and the landing indicators 1-1, 1-2,. The upper buttons 2a-1 and 2a-2 and the lower buttons 2b-2 and 2b-n are buttons for an elevator user to call an elevator car to his / her own floor.
[0016]
In the elevator management information display device according to the present invention, the control panel 4 provided in the machine room is particularly provided with the display control unit 7 for elevator management information and the elevator management information acquisition unit 6. The elevator management information acquisition unit 6 acquires elevator management information based on devices in the machine room and various sensors attached to the elevator car. The elevator management information is information for elevator maintenance personnel, and includes, for example, the position of an elevator car when an elevator confinement failure occurs. The display control unit 7 causes the elevator management information acquired by the elevator management information acquisition unit 6 to be displayed on any one of the landing indicators 1. Preferably, when the elevator management information acquisition unit 6 detects the occurrence of an elevator confinement failure, and in any of the landing panels 5, the upper button 2a or the lower button 2b is pressed for a predetermined number of seconds. The elevator management information is displayed on the landing indicator 1 provided on the landing panel 5 of the floor on which the depression is made. In addition, when the upper button 2a and the lower button 2b are simultaneously pressed for a predetermined number of seconds, the display of the elevator management information may be related to the operation procedure for the upper button 2a or the lower button 2b, or the elevator management information may be displayed. When the acquiring unit 6 detects the occurrence of the elevator confinement failure, the elevator management information may be automatically displayed on all the landing indicators 1.
[0017]
FIG. 2 is a diagram showing a display example of the hall indicator 1. As shown in the figure, the hall indicator 1 is a dot matrix display, and can display symbols such as arrows in addition to numbers and alphabets. In the example of the figure, a state in which the elevator management information is displayed by the hall indicator 1 is shown. In particular, when the elevator confinement failure occurs, the elevator management information acquisition unit 6 sets the threshold of the elevator car 100 mm below the threshold of the second floor hall. Is detected. In this case, as shown in FIGS. 6A to 6F, “2”, “F”, “↓”, “1”, “0”, and “0” are sequentially displayed on the hall indicator 1 at predetermined time intervals. . In this way, even when the hall indicator 1 that can display only a small amount of information because the floor is mainly displayed is used, the elevator management information including a large amount of information can be displayed.
[0018]
FIG. 3 is a flowchart illustrating an operation procedure for rescuing an elevator user when a confinement failure occurs, using the elevator management information display device according to the embodiment of the present invention. As shown in the drawing, in this work procedure, first, when the elevator maintenance worker arrives at the site (S11), the elevator maintenance worker performs a predetermined input operation using the upper button 2a or the lower button 2b at one of the elevator landings. I do. In response to this, the elevator management information acquisition section 6 of the control panel 4 acquires the elevator car position, and the elevator control information acquired by the display control section 7 is displayed on the hall indicator 1 (S12).
[0019]
Next, the elevator maintenance staff determines whether or not the elevator user can be rescued with the current car position based on the display of the hall indicator 1 (S13). If it is determined that the elevator user cannot be rescued without moving the elevator car up and down, the elevator head is moved to the machine room and the position of the elevator car is corrected (S14). On the other hand, if it is determined that the elevator user can be rescued at the current car position, the user goes to the landing, opens the landing door there (S15), and rescues the elevator user trapped in the elevator car to the building side. (S16).
[0020]
In this case, for example, when the step between the elevator car threshold and the landing threshold is small, the elevator maintenance staff can immediately rescue the elevator user without going to the machine room.
[0021]
The elevator management information display device described above can be variously modified. For example, in the above description, the elevator car position is treated as elevator management information, but various other information for elevator maintenance staff can be displayed on the landing indicator. In this case, if the elevator management information is displayed on the landing indicator 1 only at a predetermined timing in accordance with the operation state of the elevator or the input operation of the upper button 2a or the lower button 2b, the elevator user is carelessly confused. You don't have to.
[0022]
In the above description, a dot matrix display is assumed as the hall indicator 1. However, the same applies to a case where the hall indicator 1 is configured by a 7-segment LED. Further, even in other cases, it is possible to display information for elevator maintenance personnel separately from information for elevator users by setting the display mode to a special form different from normal use. .
