Description

TECHNICAL FIELD The present invention relates to an elevator system that allows a customer to remotely set the operation of an elevator when receiving an earthquake early warning.

2. Description of the Related Art As a prior art related to the operation of an elevator when an earthquake occurs, Patent Document 1 "Elevator Earthquake Monitoring System" is known. For example, claim 1 of Patent Document 1 states, "Earthquake monitoring system for elevators that performs an earthquake control operation when an earthquake P wave is detected and automatically returns to normal operation after a predetermined time if only the P wave is detected. , the elevator receives a P-wave detection signal from a P-wave seismometer that detects the P-wave of an earthquake, and when it returns to normal operation after a predetermined time, it sends a P-wave to an external monitoring center via a communication line. An elevator control device for outputting a wave control operation execution signal is provided, and the monitoring center receives the P-wave control operation execution signal and provides information specifying the elevator concerned and information on the P-wave control operation to the elevator maintenance staff. An elevator earthquake monitoring system characterized by transmitting.

In addition, in paragraph 0023 of the specification of the same document, in relation to earthquake control operation, "The operation control unit 3 receives a P wave detection signal and performs earthquake control operation. The control operation at the time of an earthquake is to stop the elevator car (not shown) at the nearest floor and automatically return to normal operation after a predetermined time has passed. The control operation at the time of an earthquake does not return to normal operation unless the S-wave seismometer 19 is reset by maintenance personnel after the car has stopped at the nearest floor."

Further, in claim 3 of the same document, in relation to the information transmitted to the elevator maintenance staff, ``the elevator sends the P-wave control operation implementation signal with the detection time of the P-wave and the start and return time of the control operation in the event of an earthquake. 3. The elevator earthquake according to claim 1 or 2, wherein the monitoring center includes the detection time of the P-wave and the start and return time of the control operation at the time of earthquake as the information on the P-wave control operation. time monitoring system."

As described above, in Patent Document 1, after the elevator car is stopped at the nearest floor by an earthquake control operation when a P wave is detected, an earthquake control operation is performed if an S wave is not detected within a predetermined time. There has been proposed a system for canceling and automatically returning to normal operation, in which when an earthquake control operation automatically returns to normal operation, a system for notifying an elevator maintenance worker of that fact has been proposed.

JP 2010-228877 A

Here, in paragraph 0004 of Patent Document 1, "When the P-wave seismometer 24 operates or when earthquake information is received from the emergency earthquake early warning system 26, the display 38 displays the earthquake occurrence information and prompts passengers to refrain from using the elevator. A message prompting you to do so is displayed as information."

As described above, in Patent Document 1, the reception of the P-wave detection signal is the condition for starting the "earthquake control operation", but the reception of the emergency earthquake early warning preceding the reception of the P-wave detection signal is the start of the "earthquake control operation". If it is adopted as a condition, the elevator car can be stopped at the nearest floor more quickly, and safety can be further enhanced.

On the other hand, earthquake early warnings, which are issued over a wide area with priority given to promptness, are not sufficiently accurate, so there is a possibility that an earthquake will not actually occur even in areas where an emergency earthquake warning is received. There is also In particular, immediately after a major earthquake, where there is a high probability of frequent aftershocks, false alarms are thought to increase. If it is a false alarm, even if the normal operation is automatically restored, there is a possibility that convenience for elevator users will be greatly impaired.

The present invention has been made in consideration of the above. To provide an elevator system that can be remotely set using a portable terminal such as a tablet, a smartphone, or the like.

In order to solve the above problems, an elevator system of the present invention is an elevator system comprising a car that ascends and descends in a hoistway and an elevator control unit that controls the ascending and descending of the car, and remotely monitors the elevator. A remote monitoring device comprising a remote monitoring control unit, a storage unit storing setting data of the elevator, an emergency earthquake early warning receiving unit for receiving an emergency earthquake early warning, and transmitting the received emergency earthquake early warning to the remote monitoring control unit. and a communication device having a communication control unit, wherein the storage unit of the remote monitoring device includes a setting to temporarily stop the car at the nearest floor as an operation setting of the car when receiving the earthquake early warning. Alternatively, a setting for maintaining normal operation of the car is stored.

According to the elevator system of the present invention, the customer of the elevator system (building manager, maintenance staff, etc.) can set whether or not to stop the car at the nearest floor when an earthquake early warning is received, so that the elevator does not need to be stopped. is suppressed, and convenience for elevator users is improved.

<Flowchart>
Next, the operation of the elevator system of this embodiment will be described with reference to the flowchart of FIG.

First, in step S1, the elevator control unit 41b of the remote monitoring device 4 confirms whether the elevator 1 is in normal operation. If it is in normal operation, it proceeds to step S2, and if it is not in normal operation, it repeats step S1. Note that the situation in which the elevator 1 is not in normal operation is, for example, a case where the elevator 1 is out of order and is in an emergency stop due to control operation, a case where maintenance work is being performed, or the like.

Next, in step S2, the control unit 51 of the communication device 5 checks whether the earthquake early warning receiving unit 52 has received the earthquake early warning. Then, if an earthquake early warning has been received, the process proceeds to step S3, and if not, the process returns to step S1.

In step S3, the control unit 51 of the communication device 5 notifies the control unit 41 of the remote monitoring device 4 and the control unit 61 of the monitoring center server 6 that the earthquake early warning has been received.

In step S4, the control unit 61 of the monitoring center server 6 checks the customer ID of the elevator 1 that received the earthquake early warning with the elevator DB 62 (see FIG. 3B), Notifies you that you have been registered as an earthquake early warning target area. As a result, even a customer who is not in the area where the elevator 1 is installed can know that an emergency earthquake early warning has been issued.

In step S5, the internal control unit 41a of the remote monitoring device 4 refers to the reception history 42d (FIG. 3A) of the earthquake early warning in the storage unit 42, and confirms that a predetermined time (for example, 3 minutes) ) to see if you haven't received another earthquake early warning. Then, if it is not received (that is, if it is classified as the first reception of the earthquake early warning), the process proceeds to step S6. b) go to step S9.

In step S6, the internal control unit 41a of the remote monitoring device 4 refers to the data 42a (FIG. 3A) of the elevator 1 in the storage unit 42, and confirms the operation setting of the elevator 1 at the first reception of the earthquake early warning. If the setting "car not stopped" for stopping the elevator 1 is registered, the process proceeds to step S7, and if the setting "car stop" for stopping the elevator 1 is registered, the process proceeds to step S8.

Then, in step S7, the elevator control unit 41b of the remote monitoring device 4 commands the control unit 11 of the elevator 1 to maintain normal operation. By driving, the car 12 of the elevator 1 is stopped at the nearest floor. After either step S7 or S8, the process proceeds to step S12.

In step S9, the internal control unit 41a of the remote monitoring device 4 refers to the data 42a (FIG. 3A) of the elevator 1 in the storage unit 42, and confirms the operation settings of the elevator 1 when receiving the second and subsequent earthquake early warnings. do. If the setting "car not stopped" for stopping the elevator 1 is registered, the process proceeds to step S10, and if the setting "car stopped" for stopping the elevator 1 is registered, the process proceeds to step S11.

Then, in step S10, the elevator control unit 41b of the remote monitoring device 4 commands the control unit 11 of the elevator 1 to maintain normal operation. By driving, the car 12 of the elevator 1 is stopped at the nearest floor. After either step S10 or S11, the process proceeds to step S12.

In step S12, the elevator control section 41b of the remote monitoring device 4 confirms via the control section 11 of the elevator 1 whether the P-wave detector 2 or the S-wave detector 3 has detected seismic waves. If neither the P-wave detector 2 nor the S-wave detector 3 detects seismic waves, the process proceeds to step S13, and if seismic waves are detected, the process proceeds to step S15.

In step S13, the elevator control unit 41b of the remote monitoring device 4 measures the time that has passed without detection of seismic waves after receiving the earthquake early warning. If a predetermined time (for example, 3 minutes) has elapsed without detecting seismic waves, the process proceeds to step S14, and if the predetermined time has not elapsed, the process returns to S12.

In step S14, the elevator control unit 41b of the remote monitoring device 4 commands the control unit 11 of the elevator 1 to operate normally. As a result, when the car 12 is stopped by the controlled operation in step S8 or step S11, the controlled operation of the elevator 1 is canceled and the elevator 1 returns to normal operation.

In step S15, the elevator control unit 41b of the remote monitoring device 4 brings the car 12 of the elevator 1 to an emergency stop by controlled operation. In this way, when seismic waves are actually detected, the elevator 1 is operated by control operation regardless of the setting of the data 42a (see FIG. 3A) that defines the operation of the elevator 1 when receiving an earthquake early warning. Stop and prevent automatic return to normal operation until maintenance personnel complete work such as safety confirmation. As a result, normal operation can be resumed after maintenance personnel confirm safety.

As described above, according to the elevator system of the present embodiment, emergency It is possible to switch between the operation of the elevator 1 when the earthquake early warning is received for the first time and the operation of the elevator 1 when the emergency earthquake early warning is received from the second time onwards. Therefore, considering the reliability of the earthquake early warning and the characteristics of the building where the elevator 1 is installed (whether it is likely to shake when an earthquake occurs, etc.), the customer himself/herself sets the operation of the elevator 1 when receiving the emergency earthquake early warning. be able to.

<Modification>
In the above embodiment, it is assumed that the customer has previously set the data 42a (see FIGS. 3A and 4) of the elevator 1 using the manager terminal 7. may be changed. In this case, if the detection status of seismic waves in elevators near the elevator 1 managed by the customer is provided as reference information, the customer will be able to make settings that match the actual situation.

Therefore, in this modified example, the monitoring center server 6 calculates the percentage of elevators that actually detected seismic waves among the elevators in the vicinity of the elevator 1 that received the emergency earthquake early warning, and the calculation result is used as the setting change request for the elevator 1. The customer's administrator terminal 7 is notified as reference information of rejection.

As a result, even if the customer is not in an earthquake-prone area, the reliability of the earthquake early warning can be determined quickly, so based on the information provided by the monitoring center server 6, the possibility of the earthquake early warning being a false alarm can be determined. If it is determined that the data 42a of the elevator 1 stored in the storage unit 42 of the remote monitoring device 4 is high, the content of the data 42a of the elevator 1 is quickly switched from "car stopped" to "car not stopped" to stop the unnecessary elevator 1. can be suppressed.
