[0001] The present invention relates to an elevator control operation system.
Background Art
[0002] The elevator control operation is an elevator operation pattern that is executed considering safety in an emergency such as a disaster. For example, when an earthquake occurs, the elevator control operation is executed.
[0003] By the way, long-period seismic motions generated by earthquakes often resonate with the natural periods of relatively high-rise buildings with relatively long periods. When a high-rise building resonates with a long-period seismic motion, the high-rise building will sway greatly for a long time. Therefore, in high-rise buildings, countermeasures against long-period seismic motions are important from the perspective of disaster prevention. For example, Patent Document 1 discloses a technique for predicting long-period seismic motions. Incidentally, long-period seismic motions are classified into classes according to the magnitude of the sway of the long-period seismic motions.

Summary of the Invention
[0007] The elevator control operation system according to the present invention is an elevator control operation system that performs elevator control operation, comprising: a monitoring device that predicts the class of long-period ground motion occurring in the elevator based on earthquake information transmitted from an external server; and a control panel that performs elevator control operation, wherein the monitoring device transmits the predicted class of long-period ground motion to the control panel, and the control panel performs control operation according to the class of long-period ground motion transmitted from the monitoring device.
[0008] According to the above configuration, elevator control operation can be performed according to the predicted class of long-period ground motion.
[0009] In the elevator control operation system according to the present invention, it is preferable that the monitoring device transmits the predicted class of long-period ground motion to the control panel at predetermined intervals.
[0010] With the above configuration, if multiple earthquake data points about the same earthquake are transmitted from an external server in a short period of time, the control panel does not need to predict the long-period ground motion class for each earthquake based on the earthquake data for that earthquake.
[0011] In the elevator control operation system according to the present invention, if a class smaller than the class of the long-period ground motion transmitted in the previous transmission is transmitted, it is preferable to maintain control operation corresponding to the class of the long-period ground motion transmitted in the previous transmission.
[0012] According to the above configuration, even if the magnitude of long-period ground motion decreases, the safety of the elevator can be improved by maintaining the current control operation.
[0013] In the elevator control operation system according to the present invention, it is preferable that the monitoring device predicts the arrival time of long-period ground motion based on earthquake information transmitted from an external server and transmits it to the control panel, and the control panel executes control operation from a predetermined time before the predicted arrival time.
[0014] According to the above configuration, normal elevator operation can be performed until a predetermined time before the predicted arrival time of long-period ground motion, thereby improving elevator serviceability.
[0015] In the elevator control operation system according to the present invention, if the elevator is equipped with an earthquake detector or a long-period vibration detector, the control panel preferably prioritizes executing control operation corresponding to the magnitude of the shaking detected by the earthquake detector or long-period vibration detector.
[0016] According to the above configuration, elevator safety can be improved by performing controlled operation in response to the actual shaking of the building. [Effects of the Invention]
[0017] According to the elevator control operation system of the present invention, elevator control operation can be performed according to the predicted class of long-period ground motion. [Brief explanation of the drawing]
[0018] [Figure 1] This is a schematic diagram showing an example of an embodiment: a controlled operation system. [Figure 2] This block diagram shows the configuration of a monitoring device, which is an example of an embodiment. [Figure 3] This is a time chart for predicting the class of long-period ground motion. [Figure 4] This is a block diagram showing the configuration of a control panel, which is an example of an embodiment. [Modes for carrying out the invention]
[0019] An example of an embodiment of the present invention will be described in detail below. In the following description, specific shapes, materials, directions, numerical values, etc., are examples to facilitate understanding of the present invention and can be appropriately modified according to the application, purpose, specifications, etc.
[0020] [Elevator control operation system] Using FIG. 1, the control operation system 10 will be described.
[0021] The control operation system 10 is a system that executes the control operation of the elevator 20 installed in the building 5. According to the control operation system 10, although details will be described later, the control operation of the elevator 20 can be executed according to the predicted long-period seismic motion class. The control operation system 10 includes a monitoring device 30 that predicts the class of long-period seismic motion occurring in the elevator 20 based on seismic information transmitted from the external server 15, which will be described in detail later, and a control panel 40 that executes the control operation of the elevator 20.
[0022] In the control operation system 10, the monitoring device 30 and the control panel 40 are connected by a network 50, and the monitoring device 30 and the external server 15 are connected by the network 50.
[0023] The external server 15 transmits seismic information to the monitoring device 30. The seismic information includes the earthquake epicenter, the magnitude of the earthquake epicenter, and the seismic intensity of the area where the building 5 is built. The external server 15 may be provided in the Meteorological Agency. Note that the external server of the present invention may transmit seismic information to a plurality of monitoring devices.
[0024] [Elevator] Again, using FIG. 1, the elevator 20 will be described.
[0025] The elevator 20 is installed in the building 5. The building 5 of the present embodiment is, for example, an office building. Note that the building of the present invention may be a commercial building, a public facility, or the like.
[0026] The elevator 20 raises and lowers the elevator car 21 within the hoistway 22 between each landing 6 on each floor. The elevator car 21 carries passengers and rises and lowers according to the passengers' requests, stopping at each landing 6 on each floor. The elevator car 21 is suspended from one end of a wire rope 23. A counterweight 24, whose weight is set to balance the elevator car 21, is suspended from the other end of the wire rope 23. The elevator car 21 and the counterweight 24 are raised and lowered by a lifting mechanism 26, which rotates a pulley on which the wire rope 23 is attached using an electric motor.
[0027] The elevator 20 may be equipped with an earthquake detector 27 or a long-period vibration detector 28. The earthquake detector 27 may be a mechanical earthquake detector that does not require a power supply and detects earthquakes using magnetism, or it may be an electronic earthquake detector that detects initial tremors (P-waves) and main tremors (S-waves) using a capacitive sensor.
[0028] [Monitoring device] The monitoring device 30 will be explained using Figures 2 and 3.
[0029] The monitoring device 30 remotely monitors the elevator 20. Furthermore, as will be described in detail later, the monitoring device 30 predicts the magnitude of long-period ground motion in the elevator 20 and transmits this information to the control panel 40. The monitoring device 30 is installed, for example, in the management company that manages the elevator 20.
[0030] As shown in Figure 2, the monitoring device 30 is a computer that includes a CPU 31, which is a processor for information processing, a memory 32 for storing data, and a wireless communication interface 33. The CPU 31, the memory 32, and the wireless communication interface 33 are connected by an internal bus 34.
[0031] The CPU 31 is a processor that performs information processing. The memory 32 stores the control program 35 and the control program data 36. The memory 32 may also store other programs or databases. The wireless communication interface 33 is a wireless communication module connected to the network 50 for communication with the control panel 40 of the elevator 20.
[0032] The control program 35 is executed by the CPU 31. The control program data 36 temporarily stores data when the CPU 31 executes the control program 35, as well as setting values necessary for the execution of the control program 35. The control program data 36 may also store the natural period of the building 5.
[0033] As described above, the control program 35 predicts the class of long-period ground motion occurring in the elevator 20 based on earthquake information transmitted from the external server 15 and transmits it to the control panel 40. The control program 35 may also calculate the class of long-period ground motion from the epicenter, the magnitude of the epicenter, the distance from the epicenter to building 5, and the natural period of building 5.
[0034] The classification of long-period ground motion is a system that categorizes long-period ground motion into four classes, from Class 1 to Class 4 (higher numbers indicate stronger shaking), according to the magnitude of the shaking. The classification of long-period ground motion defined under the supervision of the Japan Meteorological Agency may be used as is.
[0035] As shown in Figure 3, the control program 35 transmits the predicted long-period ground motion class to the control panel 40 at predetermined intervals. This prevents the control program from predicting and transmitting the long-period ground motion class to the control panel 40 each time multiple earthquake information items for the same earthquake are transmitted from the external server 15 in a short period of time.
[0036] The control program 35 predicts the arrival time of the long-period ground motion based on earthquake information transmitted from the external server 15 and transmits it to the control panel 40. The control program 35 may also calculate the arrival time of the long-period ground motion from the epicenter, the magnitude of the epicenter, the distance from the epicenter to building 5, and the natural period of building 5. As a result, as will be described in detail later, the control panel 40 can perform normal operation of the elevator 20 until the predicted arrival time of the long-period ground motion, thereby improving the serviceability of the elevator 20.
[0037] [Control Panel] The control panel 40 will be explained using Figure 4.
[0038] The control panel 40 controls each component of the elevator 20, such as the elevator shaft 26. The control panel 40 also performs controlled operation according to the class of long-period ground motion transmitted from the monitoring device 30, as will be described in detail later. The control panel 40 may be located in a machine room situated above the hoistway 22.
[0039] Although the magnitude of long-period ground motion is predicted for every 5 buildings, the details of the control operation and whether or not control operation is performed may differ for every 20 elevators.
[0040] The control panel 40 is a computer that includes a CPU 41, memory 42, and a wireless communication interface 43. The CPU 41, memory 42, and wireless communication interface 43 are connected by an internal bus 44.
[0041] The CPU 41 is a processor that performs information processing. The memory 42 stores a control program 45 and control program data 46 for executing the control program 45. The CPU 41 realizes various control operations by executing the control program 45 stored in the memory 42. The wireless communication interface 43 is a wireless communication module that is connected to the network 50 and communicates with the monitoring device 30.
[0042] The control program 45 is executed by the CPU 41. The control program data 46 temporarily stores data when the CPU 41 executes the control program 45, as well as setting values necessary for the execution of the control program 45.
[0043] As described above, the control program 45 executes controlled operation according to the class of long-period ground motion transmitted from the monitoring device 30. Controlled operation is an operating pattern of the elevator 20 that is performed with safety in mind during emergencies such as disasters. For example, in controlled operation according to the class of long-period ground motion, normal operation is performed at class 1, service is restricted at class 2, the elevator car 21 is stopped at a standby floor at class 3, and the elevator car 21 may be stopped at the nearest floor at class 4. A standby floor is a floor on which the elevator car 21 waits when it is not being called. The nearest floor is the floor closest to the current position of the elevator car 21.
[0044] This allows for controlled operation of the elevator 20 according to the predicted class of long-period ground motion.
[0045] The control program 45 maintains the control operation corresponding to the previously transmitted long-period ground motion class if a long-period ground motion class smaller than the previously transmitted long-period ground motion class is transmitted. For example, if the previously transmitted long-period ground motion class was class 3 and the currently transmitted long-period ground motion class is class 2, the control operation corresponding to class 3 will be maintained. The control operation may be maintained until no more long-period ground motion is predicted.
[0046] This makes it possible to improve the safety of elevator 20 by maintaining the current control operation even when the magnitude of long-period ground motion decreases.
[0047] The control program 45 executes controlled operation starting a predetermined time before the arrival time of the long-period ground motion transmitted from the monitoring device 30.
[0048] This allows for normal operation to be carried out until a predetermined time before the predicted arrival time of long-period ground motion, thereby improving the serviceability of the elevator 20.
[0049] If the elevator 20 is equipped with an earthquake detector 27 or a long-period vibration detector 28, the control program 45 prioritizes and executes controlled operation according to the magnitude of the shaking detected by the earthquake detector 27 or the long-period vibration detector 28. Depending on the magnitude of the shaking, the controlled operation according to the earthquake detector 27 or the long-period vibration detector 28 may include normal operation, service restriction, stopping the elevator car 21 at a standby floor, or stopping the elevator car 21 at the nearest floor.
[0050] This improves the safety of the elevator 20 by performing controlled operation that responds to the actual shaking or actual long-period vibrations of the building 5.
[0051] It should be noted that the present invention is not limited to the embodiments and their modifications described above, and various changes and improvements are possible within the scope of the claims of this application.
