[0013] The elevator control panel 6 is provided in the machine room 12. The elevator control panel 6 is not limited to being provided in the machine room 12, and may be provided in the hoistway 11, for example.

[0014] The earthquake sensor 7 is provided in the pit 11a of the elevator shaft 11. The earthquake sensor 7 detects the occurrence of an earthquake in the pit 11a. The earthquake sensor 7 has an acceleration sensor. When the measurement result of the acceleration sensor exceeds a preset value, the earthquake sensor 7 determines that an earthquake has occurred in the pit 11a. The detection result of the earthquake sensor 7 and the measurement result of the acceleration sensor are output from the earthquake sensor 7 and input to the elevator control panel 6.

The detection result of the earthquake sensor 9 and the measurement result of the acceleration sensor are output from the earthquake sensor 9 and input to the elevator control panel 6.

[0017] The multiple landing devices 10 are provided one for each of the multiple landings 13. Each landing 13 is formed with a landing entrance / exit 13a through which users pass. The landing device 10 is equipped with a landing door 10a and a landing indicator 10b. The landing door 10a opens and closes the landing entrance / exit 13a of the corresponding landing 13. The opening and closing of the landing entrance / exit 13a by the landing door 10a is performed in conjunction with the opening and closing of the car door 1b by the car door 1b. The display of each landing indicator 10b is controlled by the elevator control panel 6.

[0018] A display device 14 is configured from the car interior indicator 1c and the plurality of hall indicators 10b.

[0019] The system for detecting an earthquake sensor operation location of an elevator according to the first embodiment is made up of earthquake sensors 7, 8, 9, a display device 14, and an elevator control panel 6.

[0020] Fig. 3 is a diagram showing the display of the hall indicator 10b in Fig. 2. Fig. 3 shows the display of the hall indicator 10b when only the earthquake sensor 7 of the earthquake sensors 7, 8, and 9 detects the occurrence of an earthquake.

[0021] Information indicating that the elevator is out of service due to the occurrence of an earthquake is defined as earthquake outage information. Information specifying the location of the earthquake sensor that detected the occurrence of the earthquake, among earthquake sensors 7, 8, and 9, is defined as detection position information. Information specifying the floor on which car 1 is located is defined as car position information.

[0022] When an elevator is suspended due to an earthquake, the elevator control panel 6 causes the hall indicator 10b to display earthquake suspension information, detection position information, and car position information. The hall indicator 10b has multiple light-emitting elements. Some of the multiple light-emitting elements emit light, causing the hall indicator 10b to display the earthquake suspension information, detection position information, and car position information.

[0023] 3(a) shows how hall indicator 10b displays earthquake suspension information. When hall indicator 10b displays earthquake suspension information, elevator control panel 6 causes some of the multiple light-emitting elements to emit light so that "E" is displayed on hall indicator 10b.

[0024] FIG. 3(b) shows how hall indicator 10b displays detected position information. Some of the multiple light-emitting units correspond to earthquake sensor 7, earthquake sensor 8, and earthquake sensor 9, one each. Specifically, three of the multiple light-emitting units correspond to earthquake sensor 7, earthquake sensor 8, and earthquake sensor 9, one each. Of the three light-emitting units, the light-emitting unit corresponding to earthquake sensor 7 is referred to as first light-emitting unit 15a, the light-emitting unit corresponding to earthquake sensor 8 is referred to as second light-emitting unit 15b, and the light-emitting unit corresponding to earthquake sensor 9 is referred to as third light-emitting unit 15c. First light-emitting unit 15a, second light-emitting unit 15b, and third light-emitting unit 15c are arranged side by side in the height direction.

[0025] When hall indicator 10b displays the detected position information, elevator control panel 6 causes at least one of the three light-emitting units arranged in a line in the height direction to emit light. When only earthquake sensor 7 among earthquake sensors 7, 8, and 9 detects the occurrence of an earthquake, elevator control panel 6 causes first light-emitting unit 15a, which is the lowest light-emitting unit of the three light-emitting units arranged in a line in the height direction, to emit light. This causes hall indicator 10b to display the detected position information.

[0026] Fig. 3(c) shows how hall indicator 10b displays car position information. When hall indicator 10b displays car position information, elevator control panel 6 causes some of the multiple light-emitting elements to emit light so that hall indicator 10b displays a number indicating the floor where car 1 is located. Fig. 3(c) shows how hall indicator 10b displays car position information when car 1 is on the third floor.

[0027] The elevator control panel 6 switches between earthquake suspension information, detection position information, and car position information in order and causes the hall indicator 10b to display them.

[0028] Fig. 4 is a diagram showing the display of the hall indicator 10b in Fig. 2. Fig. 4 shows the display of the hall indicator 10b when only earthquake sensor 8, out of earthquake sensors 7, 8, and 9, detects the occurrence of an earthquake.

[0029] FIG. 4(a) shows how the hall indicator 10b displays earthquake suspension information, similar to FIG. 3(a).

[0030] 4(b) shows how hall indicator 10b displays detected position information. When only earthquake sensor 8 among earthquake sensors 7, 8, and 9 detects the occurrence of an earthquake, elevator control panel 6 causes second light-emitting unit 15b, which is the light-emitting unit located in the center of the three light-emitting units arranged in a line in the height direction, to emit light. As a result, hall indicator 10b displays detected position information.

[0031] FIG. 4(c) shows how the hall indicator 10b displays car position information, similar to FIG. 3(c).

[0032] Fig. 5 is a diagram showing the display of the hall indicator 10b in Fig. 2. Fig. 5 shows the display of the hall indicator 10b when, among earthquake sensors 7, 8, and 9, only earthquake sensor 9 detects the occurrence of an earthquake.

[0033] FIG. 5(a) shows the hall indicator 10b displaying earthquake suspension information, similar to FIG. 3(a).

[0034] 5(b) shows how hall indicator 10b displays detected position information. When only earthquake sensor 9 among earthquake sensors 7, 8, and 9 detects the occurrence of an earthquake, elevator control panel 6 causes third light-emitting unit 15c, which is the uppermost light-emitting unit among the three light-emitting units arranged vertically, to emit light. As a result, hall indicator 10b displays detected position information.

[0035] FIG. 5(c) shows how the hall indicator 10b displays car position information, similar to FIG. 3(c).

[0036] Fig. 6 is a diagram showing how the hall indicator 10b in Fig. 2 displays detected position information. Fig. 6 shows how the hall indicator 10b displays when the earthquake sensors 7 and 8 among the earthquake sensors 7, 8, and 9 detect the occurrence of an earthquake.

[0037] When earthquake sensor 7 and earthquake sensor 8 among earthquake sensor 7, earthquake sensor 8, and earthquake sensor 9 detect the occurrence of an earthquake, elevator control panel 6 causes first light-emitting unit 15a and second light-emitting unit 15b to emit light.

[0038] Fig. 7 is a diagram showing how the hall indicator 10b in Fig. 2 displays detected position information. Fig. 7 shows how the hall indicator 10b displays when, of the earthquake sensors 7, 8, and 9, the earthquake sensors 8 and 9 detect the occurrence of an earthquake.

[0039] When earthquake sensor 8 and earthquake sensor 9 among earthquake sensor 7, earthquake sensor 8, and earthquake sensor 9 detect the occurrence of an earthquake, elevator control panel 6 causes second light-emitting unit 15b and third light-emitting unit 15c to emit light.

[0040] Fig. 8 is a diagram showing how the hall indicator 10b in Fig. 2 displays detected position information. Fig. 8 shows how the hall indicator 10b displays when the earthquake sensors 7 and 9 among the earthquake sensors 7, 8, and 9 detect the occurrence of an earthquake.

[0041] When earthquake sensor 7 and earthquake sensor 9 among earthquake sensor 7, earthquake sensor 8, and earthquake sensor 9 detect the occurrence of an earthquake, elevator control panel 6 causes first light-emitting unit 15a and third light-emitting unit 15c to emit light.

[0042] Although not shown in the figure, when earthquake sensor 7, earthquake sensor 8, and earthquake sensor 9 all detect the occurrence of an earthquake, elevator control panel 6 causes first light-emitting unit 15a, second light-emitting unit 15b, and third light-emitting unit 15c to emit light.

[0043] Although not shown, the elevator control panel 6, like the hall indicator 10b, displays earthquake suspension information, detection position information, and car position information on the car in-car indicator 1c when the elevator is suspended due to the occurrence of an earthquake.

[0044] Next, we will explain the procedure for a maintenance worker to perform elevator recovery work using the elevator earthquake sensor operation location detection system according to embodiment 1. First, when an earthquake occurs and at least one of earthquake sensors 7, 8, and 9 detects the occurrence of an earthquake, elevator control panel 6 stops car 1 and puts the elevator out of service.

[0045] Thereafter, the elevator control panel 6 displays earthquake suspension information, detection position information, and car position information on the landing indicator 10b and the car interior indicator 1c based on the detection results of the earthquake sensors 7, 8, and 9, respectively.

[0046] The maintenance worker visually checks the detection position information displayed on the hall indicator 10b or the car indicator 1c to determine the location of the earthquake sensor that detected the earthquake. The maintenance worker then moves to the location where the earthquake sensor that detected the earthquake is located and operates the reset button of the earthquake sensor that detected the earthquake. This resets the earthquake sensor that detected the earthquake, allowing the car 1 to move.

[0047] After that, the maintenance staff starts the elevator recovery work while moving car 1. When all the recovery work is completed, the elevator is restored.

[0048] As described above, the earthquake sensor operation location detection system for an elevator according to the first embodiment includes earthquake sensors 7, 8, and 9, a display device 14, and an elevator control panel 6. Earthquake sensor 7 is provided in pit 11a of hoistway 11. Earthquake sensor 8 is provided in vertical center 11b of hoistway 11. Earthquake sensor 9 is provided in machine room 12. Elevator control panel 6 controls the display on display device 14. Elevator control panel 6 displays detection position information on display device 14 based on the detection results of earthquake sensors 7, 8, and 9. This configuration allows maintenance personnel to visually check display device 14 and determine which of earthquake sensors 7, 8, and 9 detected the occurrence of an earthquake. This eliminates the need for maintenance personnel to visit the areas where earthquake sensors 7, 8, and 9 are installed. As a result, the efficiency of elevator restoration work can be improved.

[0049] Furthermore, in the elevator earthquake sensor operation location detection system according to the first embodiment, when car 1 stops due to at least one of earthquake sensors 7, 8, and 9 detecting the occurrence of an earthquake, elevator control panel 6 switches between car position information and detection position information and displays them on display device 14. With this configuration, even if display device 14 is small in size, display device 14 can display car position information and detection position information. As a result, even if display device 14 is small in size, it is possible to inform maintenance personnel of the floor on which car 1 is located and the location of the earthquake sensor that detected the occurrence of the earthquake.

[0050] Furthermore, in the elevator earthquake sensor operation location detection system according to the first embodiment, the display device 14 has a plurality of light-emitting elements, one for each of the earthquake sensors 7, 8, and 9. The plurality of light-emitting elements are arranged in a line in the vertical direction. The elevator control panel 6 causes the detection position information to be displayed on the display device 14 by lighting up the light-emitting element, among the plurality of light-emitting elements, that corresponds to the earthquake sensor that detected the occurrence of an earthquake. With this configuration, a simple display can inform the maintenance personnel of the location where the earthquake sensor that detected the occurrence of an earthquake is located.

[0051] Moreover, in the elevator earthquake sensor operation location detection system according to the first embodiment, display device 14 has hall indicator 10b provided at hall 13. When none of earthquake sensor 7, earthquake sensor 8, and earthquake sensor 9 detects the occurrence of an earthquake, elevator control panel 6 causes hall indicator 10b to display car position information. Furthermore, when at least one of earthquake sensor 7, earthquake sensor 8, and earthquake sensor 9 detects the occurrence of an earthquake, elevator control panel 6 causes hall indicator 10b to switch between displaying detected position information and car position information. With this configuration, by visually checking hall indicator 10b, maintenance personnel can be notified of the floor on which car 1 is located and the location of the earthquake sensor that detected the occurrence of an earthquake.

[0052] Furthermore, in the elevator earthquake sensor operation location detection system according to the first embodiment, display device 14 has car in-car indicator 1c provided in car 1. When none of earthquake sensor 7, earthquake sensor 8, and earthquake sensor 9 detects the occurrence of an earthquake, elevator control panel 6 causes car position information to be displayed on car in-car indicator 1c. Furthermore, when at least one of earthquake sensor 7, earthquake sensor 8, and earthquake sensor 9 detects the occurrence of an earthquake, elevator control panel 6 causes detection position information and car position information to be displayed alternately on car in-car indicator 1c. With this configuration, by visually checking car in-car indicator 1c, maintenance personnel can be informed of the floor on which car 1 is located and the location of the earthquake sensor that detected the occurrence of an earthquake.

[0053] In the elevator earthquake sensor operation location detection system according to the first embodiment, a configuration including earthquake sensor 7, earthquake sensor 8, and earthquake sensor 9 has been described. However, this configuration is not limited to this. Any configuration including at least two of earthquake sensor 7, earthquake sensor 8, and earthquake sensor 9 will suffice. In other words, any configuration including multiple earthquake sensors, one each in at least two of pit 11a of elevator shaft 11, central portion 11b in the height direction of elevator shaft 11, and machine room 12, will suffice.

[0054] Furthermore, in the elevator earthquake sensor operation location detection system according to the first embodiment, a configuration has been described in which display device 14 displays earthquake suspension information, detection position information, and car position information. However, this configuration is not limited to this. For example, a configuration in which display device 14 displays detection position information and car position information may also be used. Alternatively, a configuration in which display device 14 displays information indicating the location of the earthquake sensor among earthquake sensors 7, 8, and 9, which has the largest acceleration sensor measurement result. With this configuration, the order in which maintenance personnel perform restoration work can be performed first in the area where the earthquake shaking is strongest.

[0055] Furthermore, in the elevator earthquake detector operation location detection system according to the first embodiment, a configuration has been described in which the display device 14 displays earthquake suspension information, detection position information, and car position information when the elevator is suspended due to the occurrence of an earthquake. However, this configuration is not limited to this. For example, the display device 14 may be configured to display earthquake suspension information, detection position information, and car position information when the elevator is suspended due to the occurrence of an earthquake and a maintenance switch provided on the elevator control panel 6 or car 1 is operated.

[0056] The earthquake sensor operation location detection system for an elevator according to the preferred embodiment 1 has been described above, but the present invention is not limited to the earthquake sensor operation location detection system for an elevator according to the above-described embodiment 1. Various modifications and conversions can be made to the earthquake sensor operation location detection system for an elevator according to the above-described embodiment 1 without departing from the scope of the claims.
