  However, in the conventional elevator control apparatus disclosed in Patent Document 1, when a failure of the earthquake detector is detected, the importance of the failure, that is, how serious the failure is, Regardless of whether it affects operations, etc., the elevator will always be controlled during an earthquake and the elevator will be suspended. There is a problem that the transportation function of the vehicle is completely stopped and the operation efficiency is remarkably lowered.

  The present invention has been made to solve such a problem. When a failure of an earthquake sensor is detected, an appropriate measure can be taken according to the importance of the failure, which is unnecessary. An elevator control device that does not cause a decrease in operating efficiency is obtained.

  The elevator control apparatus according to the present invention includes a P wave detector that detects an earthquake P wave and outputs a P wave detection signal, and an S wave detection that detects an earthquake S wave and outputs an S wave detection signal. And an elevator control means for controlling the elevator to perform a predetermined seismic control operation based on the P-wave detection signal and the S-wave detection signal. Detecting a failure of the P-wave sensor itself, outputting a P-wave sensor failure signal; and detecting the failure of the S-wave sensor itself, the S-wave sensor outputs an S-wave sensor failure signal; Based on the P-wave sensor failure signal and the S-wave sensor failure signal, the importance of the failure state of the earthquake sensor is determined from the combination of these sensor failure signals, and a predetermined earthquake corresponding to this importance is determined. Operation when sensor failure And-option, a configuration provided with a seismic sensor failure during operation selecting means for outputting an operation request during seismic sensor failure to the elevator control unit.

  In the elevator control device according to the present invention, when a failure of the earthquake detector is detected, there is an effect that an appropriate response can be taken according to the importance of the failure.

It is a block diagram which shows the whole structure of the control apparatus of the elevator which concerns on Embodiment 1 of this invention. It is a flowchart which shows operation | movement of the control apparatus of the elevator which concerns on Embodiment 1 of this invention.

Embodiment 1 FIG.
1 and 2 relate to Embodiment 1 of the present invention. FIG. 1 is a block diagram showing the overall configuration of the elevator control device, and FIG. 2 is a flowchart showing the operation of the elevator control device.
In the figure, reference numeral 1 is an elevator control means for controlling the overall operation of the elevator. From the beginning of the elevator car operation, various control operations in the event of an earthquake or failure, and the control of alarms in the event of an abnormality, etc. I am in charge.

In the building where the elevator is installed, a P wave detector 2 that detects a P wave, which is an initial tremor seismic wave generated by an earthquake, and outputs a P wave detection signal to the elevator control means 1, and is generated by an earthquake. An S wave detector 3 for detecting an S wave that is a main motion seismic wave and outputting an S wave detection signal to the elevator control means 1 is installed.
The elevator control means 1 determines that an earthquake of a predetermined magnitude or more has been detected based on the P wave detection signal and the S wave detection signal output from the P wave detector 2 and the S wave detector 3. Controls the elevator to perform a predetermined earthquake control operation.

Specific examples of the predetermined earthquake control operation include the following.
That is, first, the magnitude of the earthquake is divided into two stages, namely, the extra low earthquake that is the smallest earthquake and the low earthquake that is larger than that. And if the occurrence of an extra low earthquake is detected, after the seismic control operation such as stopping the car at the nearest floor and getting off the passengers on board, If the occurrence of a low earthquake is not detected within the time, it will be judged safe and reset to return to normal operation. On the other hand, when the occurrence of a low earthquake is detected, the operation is suspended after the earthquake-controlled operation in consideration of safety.

The P-wave detector 2 detects a failure such as an abnormality in its own power supply or CPU, and outputs a P-wave detector failure signal when a failure is detected. For this failure detection, for example, a known technique as described in Patent Document 1 described above is used.
Similarly to the P-wave sensor 2, the S-wave sensor 3 detects a failure such as its own power supply abnormality or CPU abnormality, and outputs a S-wave sensor failure signal when a failure is detected. This failure detection is also similar in that a known technique such as that described in Patent Document 1 described above is used.

The P-wave detection failure signal output from the P-wave detector 2 and the S-wave detector failure signal output from the S-wave detector 3 are input to the operation selection means 4 at the time of failure of the earthquake detector.
The seismic detector failure operation selecting means 4 determines the importance of the failure state of the seismic detector from the combination of the detected sensor failure signals based on the inputted sensor failure signals, A predetermined earthquake detector failure operation is selected, and an earthquake detector failure operation request is output to the elevator control means 1.
The elevator control means 1 controls the elevator in accordance with the earthquake detector failure operation request from the earthquake detector failure operation selection means 4.

In this embodiment, the elevator control device operates according to a series of flows shown in FIG.
First, during the normal operation of the elevator (step S1), the earthquake detector failure operation selection means 4 checks whether or not the S wave detector failure signal from the S wave detector 3 has been detected (step S1). S2). In this confirmation, when it is confirmed that the S-wave detector failure signal from the S-wave detector 3 is detected, the process proceeds to step S3, where the seismic detector failure operation selecting means 4 detects the P-wave detection. A check is made as to whether a P-wave detector failure signal from detector 2 has been detected.

  If it is confirmed in step S3 that the P-wave sensor failure signal from the P-wave sensor 2 has been detected, the process proceeds to step S4, where the seismic sensor failure operation selection means 4 is operated. Determines that both the P-wave sensor 2 that senses the initial tremor and the S-wave sensor 3 that senses the main motion are out of order and are of great importance. And an operation request at the time of failure of a seismic sensor of high importance.

In the subsequent steps S5 to S7, the elevator control means 1 that has received the operation request at the time of failure of the seismic detector of high importance causes the operation at the time of failure of the earthquake detector of high importance according to the operation request (operation 1). Is controlled.
That is, first, in step S5, the elevator control means 1 causes an abnormality of the earthquake detector to the notifying means (not shown) provided in the manager room (monitoring room) in the building or the landing of the elevator. Control to be notified.

Next, in step S6, the elevator control means 1 immediately cancels all calls already registered for the elevator.
Then, the process proceeds to step S7, where the elevator control means 1 causes a car (not shown) to travel to the nearest floor from the current car position, and stops the car when the car arrives at the nearest floor. Control to stop the operation of the elevator.

  On the other hand, if it is confirmed in step S3 that the P-wave detector failure signal from the P-wave detector 2 has not been detected, the process proceeds to step S8, and the operation selection at the time of failure of the earthquake detector is selected. The means 4 determines that the P-wave sensor 2 that senses the initial tremor is not faulty, but the S-wave sensor 3 that senses the main motion is faulty and is of importance, and based on this judgment result The operation request at the time of failure of the seismic sensor having the medium importance is output to the elevator control means 1.

Then, the process proceeds to step S9, and in the series of steps from step S9 to step S11, the elevator control means 1 that has received the operation request at the time of failure of the seismic detector in the importance level determines the importance according to the operation request. Control of the operation at the time of failure of the earthquake sensor (operation 2) is performed.
That is, first, in step S9, the elevator control means 1 causes an abnormality of the earthquake detector to the notifying means (not shown) provided in the manager room (monitoring room) or the elevator landing in the building. Control to be notified.

Next, in step S10, the elevator control means 1 performs control so as to respond to calls already registered for the elevator.
Then, when all of the registered calls have been answered, the process proceeds to step S11, where the car is stopped at the final floor of the call that has been answered last, the door is opened, and then the operation of the elevator is suspended. Control.

On the other hand, if it is confirmed in step S2 that the S-wave detector failure signal from the S-wave detector 3 has not been detected, the process proceeds to step S12, and the seismic detector failure operation selection means 4 is selected. Confirms whether or not a P-wave sensor failure signal from the P-wave sensor 2 is detected.
If it is confirmed in step S12 that the P-wave sensor failure signal from the P-wave sensor 2 has been detected, the process proceeds to step S13, and the seismic sensor failure operation selecting means 4 is selected. Determines that the S wave sensor 3 that senses the main motion is not broken, but the P wave sensor 2 that senses the initial tremor is broken and is of low importance, and the elevator control is based on the judgment result. The operation request at the time of failure of the seismic detector with low importance is output to the means 1.

Then, the process proceeds to step S14, and in the series of steps from step S14 to step S15, the elevator control means 1 that has received the operation request at the time of failure of the earthquake detector of low importance determines the importance according to the operation request. Control of the operation at the time of failure of the small earthquake sensor (operation 3) is performed.
That is, first, in step S14, the elevator control means 1 causes an abnormality of the earthquake detector to the notifying means (not shown) provided in the manager room (monitoring room) in the building or the landing of the elevator. Control to be notified.
And it progresses to step S15 and the elevator control means 1 performs control so that normal operation may be continued about the said elevator.

On the other hand, if it is confirmed in step S12 that the P-wave sensor failure signal from the P-wave sensor 2 has not been detected, the process proceeds to step S16 to select the operation when the earthquake sensor fails. The means 4 determines that neither the P-wave sensor 2 that senses the initial tremor nor the S-wave sensor 3 that senses the main movement has failed, and the failure to the elevator control means 1 based on this determination result. Outputs an operation request when there is no earthquake sensor failure.
Then, the process proceeds to step S17, and the control of the earthquake detector failure operation without failure (operation 4) according to the operation request is performed by the elevator control means 1 that has received the operation request when failure of the earthquake detector without failure. Is done. That is, in step S17, the elevator control means 1 performs control to continue normal operation for the elevator.

In this example, four types of operation at the time of failure of the earthquake detector are performed according to the combination of the failure states of the P-wave detector 2 and the S-wave detector 3. May be further reduced to simplify the configuration and to select an operation at the time of failure of the seismic detector that is more safe.
In this case, for example, when the P-wave sensor 2 that detects the initial tremor is not broken, but the S-wave sensor 3 that senses the main movement is broken, the operation at the time of failure of the seismic sensor of medium importance (operation) It is conceivable that 2) is the same as the operation at the time of failure of the seismic sensor having a high importance (operation 1).
In addition, when the S wave sensor 3 that senses the main motion is not broken but the P wave sensor 2 that senses the initial tremor is broken, the operation of the earthquake detector with a low importance (failure 3) is performed. It is conceivable that the operation is the same as the operation at the time of failure of the seismic detector having the importance level (operation 2) or the operation at the time of failure of the earthquake detector having the high importance level (operation 1).

  In the elevator control apparatus configured as described above, when the P wave sensor and the S wave sensor detect their own faults, they output a P wave sensor fault signal and an S wave sensor fault signal, respectively. Based on the sensor failure signal and the S-wave sensor failure signal, the importance of the failure state of the earthquake sensor is determined from the combination of these sensor failure signals, and at the time of a predetermined earthquake sensor failure according to this importance When an earthquake detector failure is detected by providing an earthquake detector failure operation selection unit that selects an operation and outputs an earthquake sensor failure operation request to the elevator control unit, the failure detection of the failure is detected. Appropriate measures can be taken according to importance.

  The present invention relates to a P wave detector that detects an earthquake P wave and outputs a P wave detection signal, an S wave detector that detects an earthquake S wave and outputs an S wave detection signal, and a P wave detection signal. And an elevator control means for controlling the elevator so as to perform a predetermined seismic control operation based on the S-wave detection signal.
