Description

The present invention relates to an elevator equipped with a seismic detector.

  In the conventional elevator earthquake detection device, the earthquake detection is detected as a failure of the earthquake detector, particularly, an electronic earthquake detector having a CPU for performing the earthquake detection by computer control. And an electronic seismic detector having a CPU for performing computer control, and performing seismic control operation according to the seismic scale based on the seismic detection operation information from the seismic sensor, and the magnitude of the earthquake is predetermined. If the magnitude is less than or equal to the magnitude, the earthquake detector reset command is output from the earthquake information reset means, and the time range for detecting the failure of the earthquake detector is set. Counts the number of times the reset command is output within the set time range with the failure detection timer means, and the counted number of times There is known one including extra low earthquake information failure detection counter means for determining that the earthquake detector has failed when the predetermined number of preset times is exceeded (for example, Patent Document 1). reference).

  However, in the conventional elevator earthquake detection apparatus disclosed in Patent Document 1, the seismic detector has a functional role of detecting an earthquake having a magnitude equal to or higher than a predetermined earthquake detection level. The period of non-operation (standby period) in which an earthquake of a predetermined scale or larger is not detected is much longer than the period of operation (standby period). There is a problem that it is wasteful and inefficient. Note that the main factor of the power consumption during standby is the power consumed by the CPU of an electronic seismic sensor that performs seismic sensing by computer control.

In addition, in accordance with the revised Building Standards Act Enforcement Order (2008 Decree No. 290) on the promulgation date: September 19, 2008, and the enforcement date: September 28, 2009, reserve power will be provided for control operations during earthquakes. In the event of an earthquake with a power outage, it was decided that the acceleration of the building due to the earthquake motion would be detected using batteries and private power generation facilities, etc., and the operation controlled during the earthquake.
As a result, the seismic detector is operated even in the event of a power outage, especially when the seismic detector is supplied with power from a battery power source in the event of a power outage. There is a problem that the influence is large and becomes a major factor for shortening the battery life.

  Furthermore, the detection output signal of the earthquake detector is latched at the time of earthquake detection, that is, once the detection signal is output, a remote reset signal is input from the outside for the purpose of automatic diagnosis recovery after the occurrence of the earthquake. This detection signal continues to be output until Therefore, once an earthquake detection signal is output, power is consumed to output this detection signal until it is reset, so there is a problem that it is wasteful and inefficient.

  In recent years, from the social approach to global environmental problems, it has been required to save energy as an environmental response need for elevator products, and it can be said that the above problems are serious problems.

The present invention has been made to solve such problems, and a first object is to reduce power consumption when the earthquake detector is supplied with power from a battery power source under a power outage. battery life can be extended longer, in which obtaining an elevator with a possible der Ru earthquake detecting apparatus to saving energy to improve energy efficiency.

A second object can reduce the power consumption at the time does not detect a predetermined earthquake detection level or higher scale earthquake, Ru can der to achieve energy saving to improve energy efficiency earth An elevator equipped with a seismic detector is obtained.

In the elevator according to the present invention, there is provided a elevator with a row cormorants earthquakes detecting apparatus earthquake detection output according detects a predetermined earthquake detection level or higher scale earthquake seismic scale, the earthquake detection device A low power consumption function that reduces the power consumed by itself, and an earthquake detection judgment processing unit that performs latch type low earthquake detection output and latch type high earthquake detection output as the earthquake detection output according to the magnitude of the detected earthquake If, on the basis of the low earthquake detection output and the high earthquake detection output from the earthquake detection determination processing section, and a elevator controller for control operation when a predetermined earthquake, the low-power function, a low earthquake It is effective after a predetermined time has elapsed since detection, and is configured to be effective without waiting for the elapse of the predetermined time when a high earthquake is detected .

In an elevator equipped with the earthquake detection device according to the present invention, it is possible to reduce power consumption when an earthquake having a magnitude equal to or greater than a predetermined earthquake detection level is not detected, thereby improving energy efficiency and saving energy. There is an effect that is possible.

Embodiment 1 FIG.
FIGS. 1-5, but according to the first embodiment of the present invention, FIG. 1 is a block diagram showing the overall configuration of a seismic sensing device provided in the elevator, Figure 2 is a low power consumption mode in earthquake detection device included in the elevator illustrates a transition condition to a view showing a condition for returning from the low power consumption mode in FIG. 3 earthquake detection device provided in the elevator, Figure 4 is a flow diagram illustrating the flow of operation of the earthquake detection device provided in the elevator, Figure 5 These are the figures which show the example of the LED display state in the earthquake detection apparatus with which an elevator is provided .

In the figure, reference numeral 1 denotes an acceleration sensor 1 that measures acceleration in directions of three axes orthogonal to each other (X axis, Y axis, and Z axis) and outputs it as a triaxial acceleration output signal.
The triaxial acceleration output signal output from the acceleration sensor 1 is first input to a bandpass filter 2 (BPF) that extracts and passes a signal in a predetermined frequency band.

This earthquake detection device is provided with a CPU 3 for performing the operation of the earthquake detection device by computer control.
The triaxial acceleration output signal from which the frequency component outside the predetermined frequency band is removed by the band pass filter 2 is input to the acceleration signal processing 4 performed in the CPU 3. In this acceleration signal processing 4, a triaxial acceleration vector synthesis process and an offset fluctuation monitoring process are performed based on the triaxial acceleration output signal input from the acceleration sensor 1 via the bandpass filter 2.

And the output which passed through the acceleration signal process 4 is input into the earthquake detection determination process 5 similarly performed in CPU3.
In this earthquake detection determination process 5, based on the acceleration output that has passed through the acceleration signal process 4, a P wave earthquake detection that is a non-latching signal is determined based on a comparison result with the acceleration detection level of a predetermined P wave and S wave ground motion. The output 6 and the extra low earthquake detection output 8, the low earthquake detection output 8 and the high earthquake detection output 9 which are latch-type signals are output. These earthquake detection outputs are input to an elevator control device that controls the overall operation of the elevator, and a predetermined earthquake control operation is performed based on the earthquake detection result.

Here, the P-wave earthquake detection output 6 is output when a P-wave that causes an initial tremor of an earthquake is detected. Further, when detecting an earthquake of a predetermined magnitude or larger, an extra low earthquake detection output 8, a low earthquake detection output 8, and a high earthquake detection output 9 are output in order from the smaller scale. Depending on the height of the building where the elevator is installed, detection of extra low earthquakes may be omitted. For example, when the height of the building is 60 m or less, or when a long object shake control operation is provided in a building exceeding 120 m in height for the purpose of reducing damage caused by long-period ground motion.
The extra low earthquake detection output 8, the low earthquake detection output 8 and the high earthquake detection output 9 are latch-type signals as described above, and the remote reset input 10 corresponding to each of them is sent from the elevator controller to the earthquake detection determination processing 5 These will continue to be output until they are input.

Whether or not a failure such as an abnormality of the earthquake sensor has occurred is determined by a sensor failure determination process 11 performed by the CPU 3.
The sensor failure determination processing 11 outputs a self test signal to the acceleration sensor 1, and outputs a response output from the acceleration sensor 1 that receives the input of the self test signal via the band pass filter 2 and the acceleration signal processing 4. A self-test (self-diagnosis) is performed to detect the sensor failure abnormality 11a.
When the sensor failure abnormality 11a is found, it is determined that the sensor is malfunctioning, and the sensor failure output 12 that is a non-latching signal is output to the elevator control device.

Further, the abnormality of the hardware (H / W) constituting the earthquake detection device is monitored by the H / W monitoring circuit 13, and when the H / W abnormality 11b occurs, the sensor failure determination processing 11 indicates that the sensor has failed. The sensor failure output 12 (non-latching type) is output as judged. And also, the abnormal software constituting the earthquake detection device (S / W), is monitored by the S / W monitor circuit 14, by sensor fault by detector failure determination process 11 and the S / W abnormal 11c occurs It is determined that there is a sensor failure output 12 (non-latching type).

In the event of an emergency such as a power failure, power is supplied to the earthquake detector from the battery 15 (emergency power supply) which is a standby power supply.
The DC voltage supplied from the battery 15 is converted into a predetermined DC voltage by the DC / DC power supply 16 to generate an internal voltage of the earthquake detector.
The seismic detector internal voltage generated / supplied by the DC / DC power supply 16 is monitored by the power supply voltage monitoring circuit 17, and if a power supply voltage abnormality 11d occurs, the sensor failure determination processing 11 indicates that the sensor has failed. It is determined that there is a sensor failure output 12 (non-latching type).

The failure reset input 18 and the power supply reset input from the power supply voltage monitoring circuit 17 which are performed on the sensor failure output 12 and the like from the elevator controller are externally reset input to the sensor failure determination processing 11 of the CPU 3 as these OR signals. 11e is input. That is, when at least one of the failure reset input 18 or the power supply reset input from the power supply voltage monitoring circuit 17 is input, the external reset input 11e is sent to the sensor failure determination processing 11 of the CPU 3.
Then, the external reset input 11e is output to the earthquake detection determination process 5.

  The earthquake detection device has a low power consumption function that reduces the power consumed by the earthquake detection device itself, and the CPU 3 has a low power consumption that reduces the current consumption of the CPU 3 in order to exhibit this low power consumption function. A low power consumption mode control 19 for controlling the power mode is executed. Here, the low power consumption mode refers to a sleep mode, a standby mode, or the like of the CPU 3 and is a mode that uses a function of stopping the operation of the CPU 3 and reducing current consumption.

  This low power consumption mode control 19 monitors the occurrence of a power failure, a power failure monitoring signal input 20 that is input to the low power consumption mode control 19 when a power failure occurs, and a battery voltage detection circuit 21 that detects a supply voltage from the battery 15. The input of the battery voltage input 22 that has been subjected to analog / digital conversion (A / D conversion) is received, a transition condition to a predetermined low power consumption mode to be described later is established, and the transition condition to the low power consumption mode is determined. If it is determined that it has been established, the operation of the CPU 3 is stopped and the normal measurement mode is shifted to the low power consumption mode.

  The low power consumption mode control 19 includes an external reset input 11e, that is, a failure reset input 18 or a power reset input from the power supply voltage monitoring circuit 17, a remote reset input 10 input via the earthquake detection determination process 5, a power failure monitoring signal When the input 20 and the battery voltage input 22 are received and a return condition from a predetermined low power consumption mode described later is satisfied, these signal inputs serve as an interrupt command to the CPU 3, and the operation of the CPU 3 is controlled. Return to normal measurement mode from low power consumption mode.

FIG. 2 shows a transition condition to the predetermined low power consumption mode in the low power consumption mode control 19. As described above, the low power consumption mode control 19 is performed when the OR condition that the predetermined time d1 has elapsed after the occurrence of the power failure and the battery voltage value by the battery voltage input 22 is less than the predetermined voltage Vcnt is satisfied. Then, the operation of the CPU 3 is shifted from the normal measurement mode to the low power consumption mode.
That is, when at least one of the following conditions is satisfied: the predetermined time d1 has elapsed after the occurrence of the power failure based on the power failure monitoring signal input 20, or the battery voltage value indicated by the battery voltage input 22 is less than the predetermined voltage Vcnt. The operation of the CPU 3 shifts to the low power consumption mode.

FIG. 3 shows a return condition from a predetermined low power consumption mode in the low power consumption mode control 19. As described above, the low power consumption mode control 19 receives the remote reset input 10, the failure reset input 18, the power reset input, and recovers from the power failure (is not in a power failure state). ) And an OR condition that the battery voltage value by the battery voltage input 22 is equal to or higher than the predetermined voltage Vcnt is met, these conditions serve as an interrupt command to the CPU 3, and the operation of the CPU 3 is reduced. Return from power mode to normal measurement mode.
That is, whether the remote reset input 10 is input, the failure reset input 18 is input, the power reset input is input, or the power failure recovery is confirmed based on the power failure monitoring signal input 20 and the battery voltage input 22 indicates When at least one of the conditions for whether the battery voltage value is equal to or higher than the predetermined voltage Vcnt is satisfied, the low power consumption mode is canceled and the operation of the CPU 3 returns from the low power consumption mode.

In this embodiment, the earthquake detection apparatus operates according to a series of flows shown in FIG. In addition, the range demonstrated here is the condition range in the frame enclosed with the dashed-dotted line in each figure among the transition conditions to the low power consumption mode of FIG. 2, and the return conditions from the low power consumption mode of FIG. However, the determination operation can be similarly performed for other conditions.
First, at normal time, the CPU 3 operates in the normal measurement mode (step S1). In step S2, the low power consumption mode control 19 checks whether or not the voltage of the battery 15 is equal to or higher than the predetermined voltage Vcnt based on the battery voltage input 22 from the battery voltage detection circuit 21.

In this confirmation, if it is confirmed that the voltage of the battery 15 is equal to or higher than the predetermined voltage Vcnt, the process proceeds to step S3, and the low power consumption mode control 19 determines whether a power failure has occurred based on the power failure monitoring signal input 20. Confirm whether or not. In this confirmation, if it is confirmed that no power failure has occurred, the process returns to step S2.
On the other hand, if it is confirmed in step S3 that a power failure has occurred, the elapse of the predetermined time d1 is waited in step S4, and the process proceeds to step S5 after the elapse of the predetermined time d1.

In step S5, the low power consumption mode control 19 stops the operation of the CPU 3 and makes a transition from the normal measurement mode to the low power consumption mode.
Further, when it is confirmed in step S2 that the voltage of the battery 15 is not equal to or higher than the predetermined voltage Vcnt, that is, it is confirmed that the voltage of the battery 15 is lower than the predetermined voltage Vcnt, the process directly proceeds to step S5. The low power consumption mode control 19 stops the operation of the CPU 3 and makes a transition from the normal measurement mode to the low power consumption mode.

In subsequent step S6, whether or not the power failure has been restored (recovered) is confirmed based on the power failure monitoring signal input 20, and if it is confirmed that the power failure has been restored, the process proceeds to step S7. . If it is confirmed that the power failure has not been restored, the confirmation in step S6 is repeated until the power is restored.
In step S7, whether or not the voltage of the battery 15 is equal to or higher than the predetermined voltage Vcnt is checked based on the battery voltage input 22 from the battery voltage detection circuit 21, and the voltage of the battery 15 is equal to or higher than the predetermined voltage Vcnt. If it is confirmed, the process proceeds to step S8. When it is confirmed that the voltage of the battery 15 is not equal to or higher than the predetermined voltage Vcnt (less than the predetermined voltage Vcnt), the confirmation in step S7 is repeated until the voltage is equal to or higher than the predetermined voltage Vcnt.

  In step S8, the low power consumption mode is canceled, and the operation of the CPU 3 is returned from the low power consumption mode to the normal measurement mode.

FIG. 5 shows an example of a display state by an LED for displaying an operation state of the earthquake detection device provided in the earthquake detection device, the elevator control device or the like.
There are provided an LED that displays the power supply status to the earthquake detection device, an LED that displays the failure occurrence status of the seismic detector, and an LED that displays the respective earthquake detection statuses of low, low, and high. These LEDs are all lit when the CPU 3 is in the normal measurement mode.

When the CPU 3 is in the low power consumption mode, the LED that displays the power supply state is turned on, the LED that displays the failure occurrence state of the earthquake detector is turned off, and the LED that displays the earthquake detection state is turned off or Blink.
By doing so, these LEDs constitute a display means that informs the outside that the low power consumption function is effective, and the administrator etc. are in the low power consumption mode and the low power consumption function is effective. It is easy to know that

In the earthquake detection device provided in the elevator configured as described above, when a power failure occurs in the building where the elevator is installed, a battery that is an emergency power source that supplies power to the earthquake detection device, and an earthquake detection A low power consumption function for reducing the power consumed by the device itself, the low power consumption function has passed a predetermined time d1 after the occurrence of a power failure in the building, and the voltage of the emergency power supply is a predetermined voltage Vcnt The seismic detector is connected to the battery power source in the event of a power outage by switching to the low power consumption mode by low power consumption mode control so that it is effective when at least one of the conditions is satisfied. Can reduce the power consumption and extend the life of the battery when receiving power supply from the power supply, improve energy efficiency and save energy It is possible to achieve reduction.

  In addition, a CPU for performing the operation of the earthquake detection device by computer control is further provided, and the low power consumption function stops the operation of the CPU and reduces the current consumption of the CPU, thereby reducing the power consumed by the earthquake detection device itself. By reducing the power consumption, it is possible to reduce the power consumption of the CPU, which is the main factor of standby power of the earthquake detector, and to efficiently save energy while utilizing the functions such as the sleep mode and standby mode of the CPU. .

Embodiment 2. FIG.
9 and 5 from FIG. 6, but according to the second embodiment of the present invention, FIG. 6 is a block diagram showing the overall configuration of a seismic sensing device provided in the elevator, Figure 7 is low in earthquake detection device included in the elevator illustrates a transition condition to the power mode, Figure 8 shows a condition for returning from the low power consumption mode in earthquake detection device provided in the elevator, Figure 9 is a flow diagram illustrating the flow of operation of the earthquake detection device included in the elevator FIG. 5 is a diagram showing an example of the LED display state in the earthquake detection device provided in the elevator.

  In Embodiment 2 described here, an earthquake detection processing function for a P wave that causes an initial tremor of an earthquake is separated from the CPU in the configuration of Embodiment 1 described above, and the P wave earthquake detection output is processed by the CPU. The P-wave earthquake detection output can be used as an interrupt command signal for the CPU so that the detection of the P-wave earthquake is restored from the low power consumption mode of the CPU. It is added to the conditions.

That is, among the three-axis acceleration output signals from which the frequency components outside the predetermined frequency band are removed by the bandpass filter 2, the horizontal direction, that is, the X-axis and Y-axis acceleration signals are input to the acceleration signal processing 4 performed in the CPU 3. On the other hand, an acceleration signal in the vertical direction, that is, the Z-axis acceleration signal, which is the direction of the pitching of the initial fine movement caused by the P wave, is input to the automatic reset timer circuit 23.
When the P wave is detected based on the Z-axis acceleration signal, the automatic reset timer circuit 23 outputs a P wave earthquake detection output 6 which is a non-latching signal.

In the acceleration signal processing 4 executed by the CPU 3, biaxial acceleration vector synthesis processing and offset fluctuation monitoring processing are performed on the X-axis and Y-axis acceleration output signals from the bandpass filter 2. Then, in the earthquake detection determination process 5 executed by the CPU 3, an extra low earthquake detection output 8 that is a latch type signal according to the magnitude of the earthquake detected based on the X-axis and Y-axis acceleration outputs that have undergone the acceleration signal process 4, A low earthquake detection output 8 and a high earthquake detection output 9 are output.

FIG. 7 shows a transition condition to the predetermined low power consumption mode in the low power consumption mode control 19. As described above, the low power consumption mode control 19 shifts the operation of the CPU 3 from the normal measurement mode to the low power consumption mode when OR conditions of the following conditions are satisfied.
The above conditions are that the predetermined time d2 has elapsed after the occurrence of a power failure, the battery voltage value by the battery voltage input 22 is less than the predetermined voltage Vcnt, and the power supply of the earthquake detection device is activated and the initial diagnosis is normal A predetermined time t0 elapses, a predetermined time t1 elapses after the P-wave earthquake is detected (the earthquake is not detected for the predetermined time t1), and a predetermined time t2 elapses after the extra low earthquake is detected Seismic detector operation in which a high earthquake is detected when a predetermined time t3 elapses (no earthquake is detected for a predetermined time t3) after a low earthquake is detected (earthquake is not detected for a predetermined time t2) Each condition is considered to be abnormal.

Therefore, based on the power failure monitoring signal input 20, the predetermined time d2 has elapsed after the occurrence of the power failure, or the battery voltage value indicated by the battery voltage input 22 is less than the predetermined voltage Vcnt, or the power source of the earthquake detector is activated and the result of the initial diagnosis Whether the predetermined time t0 has elapsed after normality, the predetermined time t1 has elapsed since the P-wave earthquake detection output 6 was input, or the predetermined time t2 has elapsed since the extra low earthquake detection output 8 was input At least one of the following conditions is satisfied: the predetermined time t3 has elapsed since the low earthquake detection output 8 was input, the high earthquake detection output 9 is input, or the sensor failure output 12 is input In this case, the operation of the CPU 3 shifts to the low power consumption mode.
Here, the predetermined times t1, t2, and t3 may be equal to each other.

  FIG. 8 shows a return condition from a predetermined low power consumption mode in the low power consumption mode control 19. In this way, the low power consumption mode control 19 is configured such that the remote reset input 10 is input, the failure reset input 18 is input, the power reset input is input, the power is restored from the power failure (the power is not in a power failure) and When the AND condition that the battery voltage value by the battery voltage input 22 is equal to or higher than the predetermined voltage Vcnt is satisfied and the OR condition of detecting a P-wave earthquake is satisfied, these conditions become an interrupt command to the CPU 3. Then, the operation of the CPU 3 is returned from the low power consumption mode to the normal measurement mode.

Accordingly, whether the remote reset input 10 is input, the failure reset input 18 is input, the power reset input is input, or the power failure recovery is confirmed based on the power failure monitoring signal input 20 and the battery voltage input 22 indicates The low power consumption mode is canceled and the operation of the CPU 3 is low when at least one of the battery voltage value is equal to or higher than the predetermined voltage Vcnt or the P-wave earthquake detection output 6 is input. Return from power mode.
Other configurations are the same as those in the first embodiment, and detailed description thereof is omitted.

In this embodiment, the earthquake detection apparatus operates according to a series of flows shown in FIG. In addition, the range demonstrated here is the condition range in the frame enclosed with the dashed-dotted line in each figure among the transition conditions to the low power consumption mode of FIG. 7, and the return conditions from the low power consumption mode of FIG. However, the determination operation can be similarly performed for other conditions.
First, for example, after a predetermined time t0 has elapsed after the power source of the earthquake detection device is activated and normalized as a result of the initial diagnosis, the CPU 3 operates in the low power consumption mode (step S11).

Next, in step S12, a check is made as to whether or not a P-wave earthquake motion has been detected by the automatic reset timer circuit 23. In this step, the confirmation in this step S12 is repeated until the P-wave seismic motion is detected, and if it is confirmed that the P-wave seismic motion is detected, the process proceeds to step S13 via the automatic reset timer circuit 23. P wave earthquake detection output 6 is output.
In the subsequent step S14, the low power consumption mode control 19 that has received the input of the P-wave earthquake detection output 6 as an interrupt command cancels the low power consumption mode, and the operation of the CPU 3 changes from the low power consumption mode to the normal measurement mode. Will be restored.

In the next step S15, a check is made as to whether or not an extra low earthquake motion has been detected by the earthquake detection determination processing 5. In this confirmation, when it is confirmed that the extra low seismic motion is not detected, the process proceeds to step S16 to confirm whether or not a predetermined time t1 has elapsed after the detection of the P wave seismic motion. In this confirmation, if it is confirmed that the predetermined time t1 has elapsed, the process returns to step S11, the operation of the CPU 3 is switched to the low power consumption mode, and it is confirmed that the predetermined time t1 has not elapsed. If so, the process returns to step S15.
On the other hand, if it is confirmed in step S15 that the extra low earthquake motion is detected, the process proceeds to step S17, and the earthquake detection determination process 5 outputs the extra low earthquake detection output 8.

In subsequent step S <b> 18, it is confirmed whether or not low earthquake motion is detected by the earthquake detection determination process 5. In this confirmation, when it is confirmed that the low earthquake motion is not detected, the process proceeds to step S19 to confirm whether or not the predetermined time t2 has elapsed after the detection of the extra low earthquake motion. In this confirmation, if it is confirmed that the predetermined time t2 has elapsed, the process returns to step S11, the operation of the CPU 3 is switched to the low power consumption mode, and it is confirmed that the predetermined time t2 has not elapsed. If so, the process returns to step S18.
On the other hand, if it is confirmed in step S18 that low earthquake motion has been detected, the process proceeds to step S20, and the earthquake detection determination process 5 outputs a low earthquake detection output 8.

  In step S21, a check is made as to whether or not high earthquake motion has been detected by the earthquake detection determination process 5. In this confirmation, when it is confirmed that high earthquake motion is not detected, the process proceeds to step S22 to confirm whether or not a predetermined time t3 has elapsed after detection of low earthquake motion. In this confirmation, if it is confirmed that the predetermined time t3 has elapsed, the process returns to step S11, and the operation of the CPU 3 is switched to the low power consumption mode, and it is confirmed that the predetermined time t3 has not elapsed. If so, the process returns to step S21.

On the other hand, when it is confirmed in step S21 that a high earthquake motion has been detected, the process proceeds to step S23, and the earthquake detection determination process 5 outputs a high earthquake detection output 9.
Then, in the next step S24, the low power consumption mode control 19 stops the operation of the CPU 3, transitions from the normal measurement mode to the low power consumption mode, and then proceeds to step S25, where the series of operation flow ends. .

  Here, the detection of the main motion earthquake is performed in the order of extra low earthquake, low earthquake, and high earthquake, but the detection order is not limited to this, and may be performed in an arbitrary order. Further, as in the first embodiment, detection of extra low earthquakes may be omitted depending on the height of the building where the elevator is installed.

An elevator having the above Oite the configured elevators as the row cormorants earthquakes detecting apparatus earthquake detection output according detects a predetermined earthquake detection level or higher scale earthquake seismic scale, It is equipped with a low power consumption function that reduces the power consumed by the earthquake detection device itself, and this low power consumption function seems to be effective after a predetermined time has elapsed since the detection of an earthquake with a magnitude greater than or equal to the predetermined earthquake detection level. By transitioning to low power consumption mode by low power consumption mode control, power consumption can be reduced when an earthquake of a magnitude greater than the specified earthquake detection level is not detected, improving energy efficiency and saving energy. Can be achieved.

  In addition, the low power consumption function is disabled when an earthquake caused by a P wave is detected, and when the initial fine movement is detected by the P wave, the low power consumption mode is returned to the normal measurement mode. Subsequent earthquake detection of major motion can be performed safely and reliably.
