Description

The present invention relates to seismic control system to control the elevator by using the broadcast distribution service of earthquake early warning by the mobile phone company.

  In an elevator equipped with an earthquake detector, when an earthquake shake (major motion / S wave) is detected, an earthquake control operation is performed to rescue passengers such as the nearest floor stop according to the magnitude of the earthquake. However, in such an elevator, the seismic control operation is started after the earthquake actually occurs, so if the rope is caught by the earthquake, the equipment may be damaged or confined. was there.

  On the other hand, by installing a P-wave sensor in the elevator that senses the initial tremor (P-wave) of an earthquake, an elevator configured to shift to seismic control operation earlier than the arrival of the S-wave is realized. Yes. However, since the P-wave sensor is very expensive, it is a reality that the equipment rate of the device that performs the above operation is still low. In addition, there is a request that an elevator with an express zone (with a non-stop floor on the intermediate floor) wants to acquire information on the occurrence of an earthquake earlier than the P-wave is detected and shift to control operation during an earthquake. Many.

  On the other hand, recently, the earthquake early warnings obtained from the seismic observation network spread all over Japan are distributed to various places using the Internet or satellite communication immediately after the occurrence of the earthquake. Various initiatives and proposals have been made, such as taking effective measures against the earthquake. Since this earthquake early warning is delivered immediately after the earthquake occurs, it cannot be used effectively in the event of a direct earthquake, but it takes a relatively long time for the S wave to arrive after receiving the earthquake early warning. When it is applied, that is, when a relatively large earthquake occurs in a remote place, it is possible to prevent an earthquake disaster by effectively using the received emergency earthquake bulletin.

  As a conventional elevator technology using such an earthquake early warning, when an earthquake early warning is received, the arrival time of the S wave of the earthquake at the current location is determined from the information on the epicenter and the time of occurrence of the earthquake included in the emergency earthquake early warning. There has been proposed a system that controls the control operation of an elevator during an earthquake based on the prediction result (see, for example, Patent Document 1).

  In addition, although it is not the prior art regarding an elevator, the system for receiving the said earthquake early warning using terminals, such as a mobile telephone, and the charging system which can be used in that case are proposed (for example, patent document 2). reference).

JP 2004-224469 A JP 2006-145234 A

  In the one described in Patent Document 1, if the epicenter is relatively far from the building where the elevator is installed, it is possible to shift to the control operation during earthquake earlier than the arrival of the P wave, and the express zone is set. It can be an effective means for an elevator or the like. However, in the system described in Patent Document 1, it is necessary to install dedicated receiving means for receiving the earthquake early warning in the elevator, and a dedicated line such as an Internet line or a satellite communication line is provided around the receiving means and the elevator. For this reason, there is a problem in that wiring has to be performed, and the construction requires a lot of time and labor. In addition, in order to receive the earthquake early warning, there is a problem that an expensive usage fee for a dedicated line such as a satellite communication line is generated and the running cost increases.

  Further, in a system that uses emergency earthquake warnings for elevator control, it is necessary to reliably receive emergency earthquake warnings and shift the elevator to seismic control operation. Therefore, in such a system, in order to confirm the reception status of the earthquake early warning, it is necessary to provide some means according to the system.

  The one described in Patent Document 2 only describes a system for receiving the earthquake early warning using a highly convenient terminal such as a mobile phone, a billing system used at that time, and the like. It is. Therefore, there is no disclosure regarding specific means for using the received earthquake early warning for elevator control.

The present invention has been made to solve the above-described problems. The purpose of the present invention is to use an emergency earthquake warning simultaneous broadcast delivery service provided by a mobile phone company to earthquake an elevator with an inexpensive and simple configuration. It is an object of the present invention to provide an elevator seismic control system that can be shifted to time control operation and that can easily check the reception status of emergency earthquake bulletins when necessary.

Then, when the early warning information is input to the monitoring device 6, the control panel 7 performs a predetermined operation such as shifting the elevator to the earthquake control operation, stopping the car 5 to the nearest floor, and opening the door.

  Reference numeral 10 denotes an external monitoring center composed of an elevator maintenance company or the like. The monitoring center 10 manages and monitors the elevator of the installed building 4 via the telephone network 11. That is, the monitoring center 10 and the monitoring device 6 are connected by a dedicated line (telephone line 12), and an abnormal report from the elevator to the monitoring center 10, various commands from the monitoring center 10 to the elevator, etc. 12 is performed.

  Reference numeral 13 denotes a mobile phone terminal (confirmation request transmission means) installed in the monitoring center 10. The mobile phone terminal 13 is controlled by the monitoring center 10, and periodically sends a confirmation request to the communication terminal 8 to confirm the reception state of the communication terminal 8 using the mobile phone network 3. Send. The confirmation request includes, for example, a short message service (SMS). Note that the communication terminal 8 receives the confirmation request transmitted from the mobile phone terminal 13 from the same base station that receives the earthquake early warning from the mobile phone company 2.

  In the elevator configured as described above, when the confirmation request transmitted from the mobile phone terminal 13 is received by the communication terminal 8, information indicating that the confirmation request has been received (hereinafter referred to as "confirmation request reception information") The data is transmitted from the communication terminal 8 to the monitoring device 6 via the control cable 9. The monitoring device 6 performs a predetermined operation described later when the confirmation request reception information is input.

Next, a specific configuration of the monitoring device 6 will be described with reference to FIG.
The monitoring device 6 includes a communication terminal communication unit 14, a determination unit 15, an elevator control communication unit 16 for communicating with the control panel 7, a reception recording unit 17, a health check unit 18, and a report control unit 19. The communication terminal communication unit 14 has a function for communicating with the communication terminal 8, and the breaking news reception information and the confirmation request reception information from the communication terminal 8 are input to the communication terminal communication unit 14.

  The determination unit 15 has a function of determining the bulletin reception information and the confirmation request reception information from the information received by the communication terminal communication unit 14. Note that the determination function of the determination unit 15 may be based on any method. For example, it may be determined whether the information received in the bulletin or the confirmation request is received by searching for the address of a mail received by the communication terminal 8, or may be determined based on the presence or absence of predetermined additional information. The elevator control communication unit 16 extracts the early warning reception information by the determination unit 15, that is, when the communication terminal 8 determines the reception of the emergency earthquake early warning, the elevator control communication unit 16 controls the elevator with respect to the control panel 7 during the earthquake. A predetermined signal for shifting to operation is output.

  On the other hand, when the confirmation request reception information is extracted by the determination unit 15, that is, when reception of the confirmation request by the communication terminal 8 is determined, the reception recording unit 17 records that the confirmation request reception information has been received. That is, the reception recording unit 17 stores the reception record of the confirmation request by the communication terminal 8, and whenever the communication terminal 8 receives a new confirmation request, the reception record is updated to the latest one.

  The health check unit 18 has a function (health check function) for detecting an abnormality in the reception state of the communication terminal 8 every predetermined period based on the reception record update state of the reception recording unit 17. Specifically, the health check unit 18 periodically determines whether or not the reception record of the reception recording unit 17 is updated to the latest based on the predetermined period in which the mobile phone terminal 13 transmits a confirmation request. judge. If it is detected by the above determination that the reception record of the reception recording unit 17 has not been updated normally, the health check unit 18 determines whether the reception state of the communication terminal 8 is abnormal.

  For example, when the confirmation request is set to be transmitted every 24 hours, the health check unit 18 has not updated the reception record of the reception recording unit 17 for (24 + α (α is a margin time)) time or more. Sometimes, the abnormality of the reception state of the communication terminal 8 is determined. When the monitoring device 6 includes the reception recording unit 17 and the health check unit 18 as in the first embodiment, transmission from the communication terminal 8 to the monitoring device 6 is performed by the above-described determination by the health check unit 18. Abnormalities can be detected simultaneously.

  When the health check unit 18 detects an abnormality in the reception state of the communication terminal 8, the notification control unit 19 notifies the monitoring center 10 of the occurrence of the abnormality through the telephone line 12. In this case, since some abnormality has occurred in the communication terminal 8 or its transmission / reception state, the report control unit 19 does not use the communication terminal 8 when reporting to the monitoring center 10.

Next, a specific operation of the earthquake control system having the above configuration will be described.
FIG. 3 is a diagram showing an operation flow on the elevator side in the first embodiment of the present invention, and FIG. 4 is a diagram showing an operation flow of the monitoring device in the first embodiment of the present invention.

  As shown in FIG. 3, a confirmation request (SMS or the like) is periodically transmitted from the mobile phone terminal 13 of the monitoring center 10 to the communication terminal 8 provided in the installation building 4 (S101). When a relatively large earthquake occurs, the mobile phone company 2 performs simultaneous distribution of the emergency earthquake bulletin to a predetermined area based on the emergency earthquake bulletin from the Japan Meteorological Agency 1 (S102). When the communication terminal 8 receives the confirmation request or the earthquake early warning from the mobile phone company 2 (S103), the communication terminal 8 outputs the early warning reception information and the confirmation request reception information to the monitoring device 6.

  In the monitoring device 6, the determination unit 15 extracts the bulletin information reception information and the confirmation request reception information. When the determination unit 15 detects that the communication terminal 8 has received the confirmation request from the monitoring center 10 (YES in S104), the reception recording unit 17 updates the reception record of the confirmation request reception information ( S105). On the other hand, when the determination unit 15 detects that the communication terminal 8 has received the earthquake early warning from the mobile phone company 2 (NO in S104), the elevator control communication unit 16 sends an elevator to the control panel 7. A predetermined signal for shifting to the earthquake control operation is output. Then, a predetermined operation such as nearest floor stop control is performed in the elevator (S106).

  In the monitoring device 6, it is periodically determined whether or not an abnormality has occurred in the reception state of the communication terminal 8 based on the update state of the reception record of the reception recording unit 17. Specifically, as shown in FIG. 4, the health check unit 18 periodically determines whether or not the reception record of the reception recording unit 17 has been updated to the latest based on the transmission cycle of the confirmation request. (S201). Here, if the update of the reception record cannot be confirmed even after a predetermined period has elapsed since the previous update, the health check unit 18 determines an abnormality in the reception state of the communication terminal 8 (including a failure of the communication terminal 8). (S202). When the health check unit 18 detects an abnormality in the reception state of the communication terminal 8, the notification control unit 19 notifies the monitoring center 10 using the telephone line 12 (S203).

  According to the first embodiment of the present invention, an emergency earthquake warning simultaneous broadcast delivery service provided by the mobile phone company 2 can be used to shift an elevator to an earthquake control operation at a low cost and with a simple configuration. Become. That is, it is not necessary to prepare expensive receiving means and dedicated lines as in the prior art, and the construction period can be shortened and the cost can be reduced. Note that after the installation, only the basic charge of the communication terminal 8 (mobile phone) is incurred, so the running cost can be greatly reduced.

  Moreover, according to the said structure, the reception state of the earthquake early warning in the communication terminal 8 can be easily confirmed now as needed. That is, since the communication terminal 8 does not have a dedicated line or the like for receiving the earthquake early warning, even if the reception state is good at the time of installation, the reception state is not always maintained thereafter. Absent. For example, the reception state may be deteriorated by building a high-rise building adjacent to the installation building 4 or performing a large-scale renovation work on the installation floor of the communication terminal 8. In addition, the reception state may be deteriorated due to the convenience of the mobile phone company 2.

  For this reason, if the reception state is always confirmed by the function of the health check unit 18, even if any trouble occurs, the monitoring center 10 can easily and quickly know the trouble, and prompt response thereafter. Can be achieved.
