[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a remote monitoring device, particularly a remote monitoring system in which a notification is sent to a pre-selected sub-destination monitoring center when a main destination monitoring center fails. Regarding equipment.

<Conventional technology> In recent years, in the management of equipment in buildings, rather than having a manager permanently stationed, building equipment (iii) can be remotely monitored from a monitoring center via communication lines for multiple buildings. There is a tendency for this method to be adopted.

For this type of remote monitoring device, for example, Japanese Patent Laid-Open No. 61-121
As disclosed in Japanese Patent No. 551, sensors are installed in equipment such as air conditioning equipment, power receiving and transforming equipment, and elevators, and terminal devices connected to these sensors are installed in the same building.

The monitoring center and the terminal device are interconnected through a communication line, and when equipment malfunctions, a notification is sent from the terminal device to the monitoring center via the communication line, and the monitoring center uses the communication line to adjust the building's equipment. I'm monitoring it.

Since this type of remote monitoring equipment requires constant monitoring 24 hours a day, a backup device is installed in case a failure occurs within the monitoring center, and in the event of a failure, this backup device can be accessed manually or automatically. Switching is performed and measures are taken to prevent unmonitored conditions from occurring.

<Problem to be solved by the invention> Since there is a limit to the number of terminal devices that can be constantly monitored in one monitoring center, as the number of buildings increases, it becomes necessary to maintain a detailed and complete monitoring system. In order to do so, it is necessary to increase the number of monitoring centers.

Even when installing and expanding monitoring centers in a distributed manner, it is not acceptable for monitoring centers to fail and result in a non-monitoring state. Therefore, either a two-system configuration with backup equipment for each system, or a highly reliable system with no risk of component failures is required. Use or must use sexual equipment.

However, if a two-system configuration is used or if highly reliable components with no risk of failure are used, the equipment cost for each distributed and expanded monitoring center increases, resulting in extremely poor investment efficiency. be.

The present invention was made in view of the current state of this type of remote monitoring equipment as described above, and its purpose is to reduce equipment costs when expanding and distributing monitoring centers, and to provide detailed and high reliability. It is an object of the present invention to provide a remote monitoring device that can constantly monitor a computer without causing a non-monitoring state.

Means for Solving the Problems> To achieve the above object, the present invention provides a system in which terminal devices are installed in a plurality of buildings, and equipment connected to the terminal devices is remotely monitored via a communication line. In a remote monitoring device equipped with a plurality of monitoring centers, the terminal device includes a switching device that switches alarms to a preselected sub-destination monitoring center when a main alarm destination monitoring center of the terminal device fails. an identification device for identifying reception of an alert from the terminal device having the monitoring center as a sub-alert destination, a storage device for storing information regarding the alert identified by the identification device, and the storage device. The monitoring center is provided with a communication device that transmits the information stored in the communication device to the main destination monitoring center for the identified alert after the failure has been restored.

Function> In the present invention, when a monitoring center that has jurisdiction over a plurality of terminal devices in a predetermined area malfunctions and becomes unable to monitor, the monitoring center that has become unable to monitor becomes the main reporting destination in the event of an equipment accident. The terminal device detects a failure in the monitoring center, and this detection activates the switching device.

By operating this switching device, the destination of notification when an accident occurs in the equipment of the terminal device is switched to the preselected sub-destination monitoring center.

Therefore, when an accident occurs in equipment, the terminal device sends an alert to the monitoring center that is the secondary notification destination, and the monitoring center that is the secondary notification destination quickly and accurately responds to equipment accidents. processing is performed.

At this time, the identification device of the monitoring center that is the sub-destination of the alert identifies the receipt of the alert with that monitoring center as the sub-destination, and information regarding the identified alert is stored in the storage device. be done.

After the failure recovery of the primary destination monitoring center for the alert identified by the identification device, information is stored in the storage device from the communication device of the monitoring center that is the secondary alert destination to the primary alert destination monitoring center. is transmitted, and the monitoring center that is the main destination is notified of the monitoring information during the failure period.

<Example> Hereinafter, an example of the present invention will be described in detail with reference to FIG.

It is composed of a connected monitoring center 2a.

Further, each terminal device 3a is provided with a switching device 31a, and by this switching device 31a, the terminal device 3a is normally connected to the monitoring center 2a of the same monitoring block IA so as to issue an alarm. When the alarm cannot be issued due to a failure of the monitoring block 2a, the switching device 31a is activated to switch the connection so that the alarm is issued to the later-described monitoring center 2b of another monitoring block IB.

In the above-mentioned monitoring center 2a, the first communication device 21a that receives information from the terminal device 3a is connected to the communication line 51, and the output terminal of this first communication device 21a is connected to the communication line 51.
A processing device 22a is connected that processes the received information and distributes necessary information to each device. Connected to the output terminal of the processing device 22a are a display device 23a and a printing device 24a for reporting received information to a supervisor, as well as an identification device 25a that distinguishes received information into information within its jurisdiction and information outside its jurisdiction. has been done.

Further, the output terminal of the identification device 25a is connected to the identification device 25a.
A main storage device 26a that stores information within the jurisdiction distinguished by
and a sub-storage device 27a that stores information outside the jurisdiction distinguished by the identification device 25a.

Furthermore, the monitoring center 2a includes a monitoring center 2b, which will be described later.
A second communication device 28a is provided which is connected to a second communication device 28b by a communication line 52, and this second communication device 2
8a is connected to the main storage device 26a and the sub storage device 27a.

Therefore, the secondary storage device 2
Information outside the jurisdiction stored in 7a is transmitted to the monitoring center 2b (described later) via the communication line 52, and information outside the jurisdiction transmitted from the monitoring center 2b (described below) via the communication line 52 is It is configured to be stored in the main storage device 26a by the second communication device 28a.

On the other hand, also in the monitoring block IB, the equipment 4b, the terminal device 3b, the first communication device 21b, the processing device 22b,
The display device 23b, printing device 24b, identification device 25b, main storage device 26b, sub-storage device 27b, and second communication device 28b constitute the same circuit as the above-mentioned monitoring block IA.

Then, the switching device 3 of the terminal device 3a of the monitoring block IA
1a and the switching device 3 of the terminal device 3b of the monitoring block IB.
1b is connected to the first one of the monitoring block IA, respectively.
and the first communication device 21b of the monitoring block IB, and the second communication device 28a of the monitoring block IA and the second communication device 28b of the monitoring block IB.
are connected to each other by a communication line 52.

Next, the operation of the embodiment will be explained.

First, a case will be described in which the main alert destination monitoring block is operating normally.

For example, equipment 4a of a building in monitoring block IA
If an accident occurs that causes the equipment to become abnormal, this equipment 4a
A sensor (not shown) detects an abnormality, and an abnormality signal is input to the terminal device 3a. In this case, since the switching device 31a of the terminal device 3a is switched to the first communication device 21a side of the monitoring block IA, the communication line 5 from the terminal device 3a
1, abnormality information is reported to the first communication device 21a of the monitoring center 2a, which is the main destination.

The abnormality information received by the first communication device 21a of the monitoring center 2a that is the main destination is input to the processing device 22a, the received abnormality information is edited by the processing device 22a, and the edited abnormality information is sent to the monitoring center. The information is displayed on the display device 23a and printed by the printing device 24a in order to notify the user.

Further, the abnormality information received by the processing device 22a is
The information is also input to the identification device 25a, and the identification device 25a4 identifies and determines that the abnormality information has been reported from the terminal device 3a within its jurisdiction with the monitoring center 2a as the main destination, and the abnormality information is stored in the main memory. 26a.

In this way, the supervisor who confirms the abnormality information displayed on the display device 23a and printed by the printing device 24a takes measures corresponding to the abnormality information, and, for example, the service provider of the equipment 4a that is in an abnormal state. From there, a service person goes to the site and performs restoration work on the equipment 4a that is in an abnormal state.

Next, a case will be described in which the main reporting destination monitoring center is out of order and it is impossible to report abnormality information to the primary reporting destination.

In this case, the equipment 4 of the building in monitoring block IA is
The terminal device 3a that received the abnormal signal of a is the monitoring center 2a.
When it is detected that the main alarm cannot be issued due to a failure, the switching device 31
a is activated, the terminal device 3a is switched and connected via the communication line 51 to the first communication device 21b of the monitoring center 2b of the monitoring block IB, which is the sub-alert destination selected in advance.

Therefore, abnormality information is reported from the terminal device 3a via the communication line 51 to the first communication device 21b of the monitoring center 2b, which is the sub-report destination.

This abnormality information is transmitted from the first communication device 21b to the processing device 2.
2b and edited in the processing device 21b, the edited abnormality information is printed by the printing device 24b displayed on the display device 23b for reporting to the supervisor.

Further, the abnormality information received by the first communication device 21b by the processing device 22b is also input to the identification device 25b,
Identification bag! 25b identifies and determines that the abnormality information has been issued from the terminal device 3a outside the jurisdiction with the monitoring center 2b as the secondary notification destination, and in this case, the abnormality information is stored in the secondary storage device 27b.

In this way, the supervisor of the monitoring center 2b who has confirmed the abnormality information displayed on the display device 23b and printed by the printing device 24b from the terminal device 3a outside the jurisdiction, replaces the supervisor of the monitoring center 2a. , take measures corresponding to the abnormality information, and, for example, remove the equipment 4a that is in an abnormal state.
Restoration work will be carried out by service personnel.

When the equipment 4a is restored to a normal operating state through this restoration work, a restoration signal is transmitted from the second communication device 28a of the monitoring center 2a to the second communication device 28b of the monitoring center 2b via the communication line 52. . The second communication device 28b that has received this recovery signal transmits the abnormality information stored in the secondary storage device 27b with the monitoring center 2b as the secondary notification destination via the communication line 52 to the second communication device 28b of the monitoring center 2a. It is transmitted to the communication device 28a.

The abnormality information transmitted to the second communication device 28a of the monitoring center 2a is stored in the main storage device 26a by the second communication device 28a.

According to the embodiment, even if the monitoring center 2a of the monitoring block IA fails, the abnormality information can be received at the monitoring center 2b of the monitoring block IB, which is a sub-report destination outside the jurisdiction, and the monitoring center When the failure of 1a is restored,
The abnormality information stored in the secondary storage device 27b of the monitoring center 2b is transmitted to the monitoring center 1a.

Therefore, even if a failure occurs in the monitoring center 2a that is the main destination for the terminal device 3a, the monitoring of the terminal device 3a is always performed reliably without going into a non-monitoring state. Since the abnormality information of the terminal device 3a that occurred during the period is transferred, the main storage device 26a of the monitoring center 2a stores complete information including during the failure period, and is fully compatible with information searches and report creation. You can.

Further, since the monitoring centers 2a and 2b do not have a two-system configuration and do not use highly reliable equipment that is unlikely to fail, the manufacturing cost of the entire device can be reduced.

In addition, in the embodiment, a case has been described in which the terminal device 3a of the monitoring block IA is in an abnormal state and the operation is performed with the monitoring center 2b of the monitoring block IB as the secondary notification destination, but the present invention is limited to the embodiment. Not a thing, but a monitoring block I
When the terminal device 3b of B is in an abnormal state, the same operation is performed using the monitoring center 2a of the monitoring block IA as the secondary notification destination.

Further, in the embodiments, two monitoring blocks are provided and each monitoring center is provided with a first communication device and a second communication device, but the present invention is limited to the embodiments. Generally, a plurality of monitoring blocks can be provided, and the first communication device and the second communication device can be configured into one communication device.
