DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a remote monitoring system according to the present invention, and more particularly to a remote monitoring system which reliably responds to alarm information received at a control center.

[0002]

2. Description of the Related Art A conventional remote monitoring system includes a terminal device for monitoring equipment such as elevators installed in a plurality of monitored buildings, and a remote device selectively connected to these terminal devices via a communication line. 2. Description of the Related Art There is widely known a control center including a control center located on the ground and a plurality of dispatch bases in which dispatch personnel who inspect and maintain equipment installed in a monitored building are on standby. This control center stores communication equipment that communicates with terminal devices, processing equipment that analyzes alarm data and creates alarm information, and stores information necessary for monitoring and abnormalities of equipment that occurred in the past. And a distribution device that communicates with the dispatch base, and a display operation device that monitors when the dispatch base is not in business, such as on a holiday night. Also, the dispatch base is
A dispatch instruction device for inputting a display of alert information and a response to the alert, and an alert reception notifying device for notifying dispatch personnel in the dispatch base by sound or light that the alert information has been generated. I have.

[0003] In the remote monitoring system having such a configuration, when an abnormality occurs in the operation of the equipment installed in the monitored building, a terminal device monitoring the equipment detects this abnormality, and details of the abnormality. The alarm data composed of the above is created and transmitted to the control center via the communication line. The control center, which has received the alarm data by the communication device, transmits the data to the processing device, analyzes the alarm data by the processing device, and generates an alarm including the name of the building, the name of the equipment having an abnormality, and the like. The report information is created and distributed via the distribution device to the dispatch instruction device of the dispatch base that controls the monitored building where the abnormal equipment is installed. The dispatch base receiving the alert information displays the content of the alert information on the display screen of the terminal, and operates the alert reception notifying device to notify the dispatched personnel on standby that the alert has been issued. . The dispatched personnel who confirms the alarm information rushes to the building to which the alarm data has been transmitted, and checks and repairs the equipment in which the abnormality has occurred.

[0004]

However, in the conventional remote monitoring system, when the dispatching staff who are supposed to be on standby are all dispatched, and the receiving operation for the alarm information cannot be performed at the dispatching base, the control center is required. Since the receiving side cannot confirm that the receiving operation cannot be performed, there is a danger of serious consequences if the alarm information indicates an abnormality of equipment affecting human life. Also, if a failure occurs on the communication line or the dispatch instruction device after the dispatching staff has been dispatched to the dispatch base and the dispatch information has been received, it is not possible to notify the control center that the reception operation has been performed. In such a case, the occurrence of a failure in the communication line or the dispatch instruction device cannot be confirmed, and the monitoring operation cannot be performed.

[0005] It is an object of the present invention to perform a monitoring operation even when a dispatching person is absent at a dispatching base or a failure occurs in a communication line, a dispatching instruction device, etc. after distribution of alarm information. It is to provide a remote monitoring system that can be used.

[0006]

According to the present invention, in order to achieve the above object, terminal devices for monitoring the operation of facility equipment are respectively arranged in monitored buildings, and the terminal devices are connected to remote terminals via a communication line. A processing device for connecting a control center, connecting a dispatch base for maintenance and repair of the equipment and equipment to the control center, and generating alarm information for the alarm data from the terminal device in the control center. And a display operation device capable of displaying the alarm information, wherein the dispatch base has a dispatch instruction device capable of displaying the alarm information from the control center. The device is configured to transmit acknowledgment information when operated on the alarm information from the control center,
The processing device is configured to, when there is no reception confirmation information from the dispatch instruction device for the alarm information from the control center, transfer the alarm information to the display operation device and display the alarm information. Features.

[0007] As described above, the remote monitoring system of the present invention provides the alarm information to the display and operation device of the control center when the reception confirmation information is not transmitted at the dispatch base in response to the alarm information from the control center. Is automatically transferred and displayed, so that no dispatch personnel are present at the dispatch base and no operation is performed to confirm receipt of information from the control center at the dispatch base, or that the dispatch information is distributed. Later, if a failure occurs in the communication line or the dispatch instruction device and it becomes impossible to transmit the reception confirmation information, the alert information is automatically transferred to the display and operation device of the control center for display. In this case, since the response staff is on standby 24 hours a day, it is possible to surely deal with the alarm information while confirming whether or not the alarm information has been transferred.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a remote monitoring system according to an embodiment of the present invention, and is provided in a plurality of monitored buildings and detects terminal devices 1a to 1a to detect an abnormality or an operation state of equipment such as an elevator in each building. 1n is connected to a control center 2 for remotely monitoring via a communication line L1, and a dispatch base 3 is connected to the control center 2 via a communication line L2. At the control center 2, control personnel are on standby 24 hours a day to perform control duties, and at the dispatch base 3, dispatch personnel who are dispatched to a building in charge to perform maintenance and inspection of equipment such as elevators are on standby. ing.

The control center 2 includes a plurality of communication devices 21a to 21m for receiving, via a communication line L1, alarm data including information on state changes of equipment in a building detected by the terminal devices 1a to 1n. The alarm data received by the communication devices 21a to 21m is analyzed and processed, and information such as the name of the equipment having a status change, the name of the installed building, the state of the equipment, and the name of the dispatch base are used as the alarm information. A processing unit 22 for conversion; a database 23 for storing information necessary for generating the alarm information by the processing unit 22 and a state change of the equipment that has occurred in the past; and alarm information processed by the processing unit 22. And a plurality of distribution devices 24a to 24i for distributing the information to the dispatch base 3 via the communication line L2, and displaying the alert information instead of the dispatch base 3 when the dispatch base 3 is absent, such as on holidays or at night. Cormorant is a plurality of display devices are provided with a display operation device 25A～25j. Dispatch base 3 is
Communication line L from distribution devices 24a to 24i of control center 2
The dispatch instruction device 31 which is a display operation means for receiving and displaying the alert information sent via the communication line 2, and the alerting means for notifying the corresponding staff of the dispatch base 3 when the alert information is received. The information receiving / notifying device 32 is provided.

If the terminal device 1a shown in FIG. 1 detects an abnormality in the equipment, the terminal device 1a uses its own unique identification number, data indicating the state of the equipment, and the like as alarm data. The data is transmitted to the communication device 21a of the control center 2 via the communication line L1. Communication device 2 receiving this
1a transmits the alarm data to the processing device 22, and the processing device 22 extracts the identification number from the received alarm data and installs the terminal device 1a stored in the database 23 using the identification number as a search key. Information such as the name and address of the building, the name of the equipment whose status has changed, the status of the equipment, the name and telephone number of the contact, and the dispatch base are extracted. Further, the processing device 22 creates alert information based on the information extracted from the database 23, stores the alert information in the database 23, and transmits the information to the distribution device 24a.

The distribution device 24a that has received the alarm information
Distributes the alert information via the communication line L2 to the dispatch instruction device 31 of the dispatch base 3 corresponding to the alert information in step S1 of the flowchart shown in FIG. Next, in step S2, the processing device 22 checks whether the distribution device 24a has completed communication with the dispatch instruction device 31. If the distribution device 24a has terminated communication with the dispatch instruction device 31 in step S2, the At the base 3, the alarm information received by the dispatch instruction device 31 is displayed on the display screen of the dispatch instruction device 31, and the buzzer and lamp of the alarm reception notifying device 32 are sounded and blinked to receive the alarm information. Dispatched base 3
Notify the dispatched personnel who are on standby. At this time, the dispatch staff of the dispatch base 3 confirms that the alert reception notifying device 32 has been operated, performs a reception confirmation operation from the dispatch instructing device 31, and displays the alert information displayed on the screen of the dispatch instructing device 31. After confirming the contents of the above, go to the building where the equipment was abnormal and inspect or repair the equipment. When the dispatcher performs an operation for confirming reception, the dispatching instruction device 31 stops the sounding buzzer and turns off the lamp, and transmits the signal to the distribution device 24 of the control center 2 via the communication line L2.
The reception confirmation information is transmitted to a. When this is received by the distribution device 24a of the control center 2, the processing device 2
2, the processing unit 22 searches the database 23 using the identification number of the terminal device 1a included in the reception confirmation information as a search key, extracts the previously stored alarm information, and issues the alarm. The reception confirmation data indicating that the dispatch base 3 has received the alert information is set in the information, and stored in the database 23 again.

On the other hand, if the reception confirmation operation is not performed on the alert information because of the fact that all the dispatched members of the dispatch base 3 are dispatched, the dispatch instruction device 31 transmits the receipt confirmation to the distribution device 24a in step S3. I cannot send information. Here, the dispatch instruction device 31 determines that the dispatch personnel is absent at the dispatch base 3 after a predetermined set time, for example, 3 minutes, and the dispatch instruction device 31 may confirm reception in step S4. The information indicating that the reception is not possible is distributed to the distribution device 24a of the control center 2 via the communication line L2. The distribution device 24a that has received the non-receiving information
Transmits the information to the processing device 22. When the processing device 22 receives the reception-unsupported information, the processing device 22 uses the identification number unique to the terminal device included in the information as a search key and searches the database 2
3 and retrieves the alarm information, and transmits the alarm information extracted in step S6 to the display operation device 25a. The display / operation device 25a that has received the alert information displays the alert information on the display screen, and then notifies the response staff who stands by in the control center 2 for 24 hours of the abnormal alert.

Then, when the response staff in the control center 2 performs an operation of confirming the alarm information displayed on the display / operation device 25a, the reception confirmation information is transmitted to the processing device 22,
The processing device 22 that has received the reception confirmation information sets the reception data indicating the reception in the alert information in the database 23 in the same manner as the normal processing, stores it in the database 23, and ends the processing. Further, when the processing device 22 checks whether the communication from the distribution device 24a to the dispatch instruction device 31 has been completed in step S2, if the communication has not been terminated, the failure occurs in the dispatch instruction device 31 or the communication line L2. It is determined that there has been a notification, and in step S6, the alarm information is distributed to the display / operation device 25a in the control center 2, and the corresponding personnel in the control center 2 are displayed on the display / operation device 25a in the same manner as described above. An operation for confirming information is performed, and the processing device 22 is checked.
The acknowledgment information is sent to and processed.

By the way, although very rarely, if a failure occurs in the communication line L2 after the distribution information is distributed from the distribution device 24a to the dispatch instruction device 31, the reception confirmation information from the dispatch instruction device 31 is determined in step S3. Waits for reception. At this time, at the dispatch base 3, the alarm reception notification device 3
The notification of the alarm information is performed by the operation of step 2, and the operation confirmation operation is performed by the dispatcher. Therefore, the transmission instruction device 31 transmits the reception confirmation information to the distribution device 24 a of the control center 2 via the communication line L <b> 2. Will do it.

However, the transmission cannot be performed due to the failure of the communication line L2, and the distribution device 24a
Cannot receive the reception confirmation information in step S3 and the reception non-correspondence information in step S4, so the process proceeds to the next step S5. If the reception confirmation information and the reception non-correspondence information are not transmitted from the dispatch instruction device 31 even after a lapse of a preset time, for example, 4 minutes, set in this step S5, the detection means of the processing device 22 has When it is determined that the alarm has occurred, the database 23 is searched to distribute the alarm information. The alarm information that has passed the specified time has been searched for, extracted, and transmitted to the display operation device 25a. The display operation device 25a that has received the alarm information displays the alarm information on the display screen in step S6, and notifies the response staff in the control center 2 of the abnormal alarm. Next, when the response staff in the control center 2 performs an operation of confirming the alert information displayed on the display / operation device 25a, the reception confirmation information is transmitted to the processing device 22, and the reception confirmation information is received. Processing device 22
Sets the received data indicating reception to the alarm information in the database 23 in the same manner as the above-described processing, stores the data in the database 23, and ends the processing. In addition, when a failure occurs in the dispatch instruction device 31 after receiving the alarm information, the same processing as when a failure occurs in the communication line L2 can be dealt with. Here, the specified time of the dispatch instruction device 31 and the prescribed time of the processing device 22 can be changed, but the data processing time from the dispatch instruction device 31 to the communication line L2 is taken into consideration.
It is necessary to set the specified time of 2 longer.

[0016]

As described above, in the remote monitoring system according to the present invention, there is no dispatched person at the dispatched base,
If a failure occurs in the communication line or the dispatch instruction device after the alert information is delivered, and there is no reception confirmation information from the dispatch base for the alert information from the control center, the alert information is automatically sent to the control center. In such a special case, the response personnel of the control center, which is on a 24-hour basis, can respond to this and send the information to the alarm information. It will be possible to respond reliably.
