[0036] figure 1 The structure of an elevator for outdoor sightseeing to which the elevator control device of the present invention is applied is shown. In the figure, reference numeral 1 denotes a car; 2, a hoist; 3, a main rope; 4, a counterweight; 5, a car control device; 6, a display device in the car; and 7 denotes a notification device in the car.

[0037] In such an elevator for outdoor sightseeing, a car 1 is installed outdoors of a building. The car 1 is raised and lowered between the top floor and the bottom floor of the building. In addition, a specific one of the docking floors is prepared as the shelter layer 8 . The Shelter 8, for example, such as figure 2 The settings shown are on the top layer. This protective layer 8 is covered from the outside and serves as a service layer against direct lightning strikes and the like.

[0038] Here, the elevator control device 11 is installed together with a hoist 2 in a machine room 10 which is arranged higher than th...

[0057] Next, a second embodiment of the present invention will be described.

[0058] In the second embodiment, in the above figure 1 In the structure, the present invention is characterized in that the wind speed is detected by using a wind speed detecting means 15b provided on the weather information detecting means 15, thereby performing the control operation in two stages according to the wind speed value. Figure 4 Show one of its processing operations.

[0059] Figure 4 is a flowchart showing strong wind control operation processing of the elevator control device 11 according to the second embodiment of the present invention.

[0060] During the operation of the elevator, the wind speed near the height of the car 1 is detected by the wind speed detection means 15b provided on the weather information detection means 15 (step B11). The wind speed detected by the wind speed detection device 15b is less than A (m / s) ("No" in step B12), and the elevator control device 11 ...

[0069] Next, a third embodiment of the present invention will be described.

[0070] In the third embodiment, in the above figure 1 In the structure, the present invention is characterized in that a control operation is performed according to the amount of rain or snow by detecting the amount of rain or snow by using a rain or snow detection means 15c provided on the weather information detection means 15. Figure 5 Show one of its processing operations.

[0071] Figure 5 is a flowchart showing the rain or snowfall amount control operation processing of the elevator control device 11 according to the third embodiment of the present invention.

[0072] While the elevator is in operation, the amount of rain or snow is detected by a rain or snow detection means 15c provided on the weather information detection means 15 (step C11). The above-mentioned rain or snowfall detecting device 15c includes, for example, a rain or snowfall meter for measuring the amount of rain or snowf...

Abstract

A weather information detection device (15) for detecting information on weather. An elevator control device (11) conducts controlled operation in accordance with weather information detected by the weather information detection device (15). The controlled operation avoids a passenger cage (1) being affected directly by change of weather. For example, the elevator control device (11) detects approach of thunder cloud by a lightning detection device (15a) of the weather detection device (15). When there is a possibility of a lightning strike in the vicinity of the elevator, the passenger cage (1) is evacuated by the elevator control device (11) to an evacuation floor (8) free from influence of a direct lightning strike. Thus passenger safety is secured and damage to the passenger cage can be prevented.

Description

technical field [0001] The present invention relates to an elevator control device for performing a control operation corresponding to weather changes such as lightning strikes, strong winds, and rain or snowfall in an elevator for outdoor sightseeing. Background technique [0002] In a general elevator, since a car (cabin of the elevator) is provided in a building, the elevator is not directly affected by weather changes. However, if the building is struck by lightning, for example, a lightning current flows through the elevator shaft, thereby destroying the electrical system of the elevator control, and one or more passengers may be locked in the car. Also, if the building sways due to strong winds, the car will sway at the same time, and passengers trapped in the car may feel uneasy. [0003] Usually, in order to solve the above-mentioned problem, the accident that one or more passengers are trapped in the car is avoided by, for example, using a lightning sensor to sense...
