It includes a monitoring device 1 that monitors the equipment 4 installed at ~D, and a notification device 2 that notifies the status of the equipment 4.

Remote monitoring base X is a base for remotely monitoring and managing a plurality of buildings A to D. At remote monitoring base X, information on multiple buildings A to D is aggregated. An example of the remote monitoring base X is a central control center.

The remote monitoring system may include a plurality of remote monitoring bases X. In this case, the plurality of remote monitoring bases X are configured to share the areas that they monitor and manage. Further, the plurality of remote monitoring bases X are configured in a complementary manner. For example, if a problem occurs in any of the multiple remote monitoring bases X, another remote monitoring base Can be monitored and managed.

The Internet line N connects the remote monitoring base X and each of the plurality of buildings A to D via the group management server Z. This makes it possible for the remote monitoring base X to obtain information on a plurality of buildings A to D. The remote monitoring base X is connected to the Internet line N using a base-side router Rx. Each of the plurality of buildings A to D is connected to the Internet line N using building routers Ra to Rd (only the router Ra of building A is shown in the figure).

In this embodiment, a remote monitoring base X, a group management server Z, and a plurality of buildings A to D are connected through a closed network constructed using a VPN (Virtual Private Network). In this case, the base-side router Rx installed at the remote monitoring base X and the building-side routers Ra to Rd installed in the plurality of buildings A to D are each VPN routers. However, the configuration is not limited to this, and the remote monitoring base X, group management server Z, and multiple buildings A to D may be connected to an open line via a security device such as a firewall. .

The group management server Z is configured to receive notification signals Sh from the notification devices 2 installed in each of the buildings A to D. The group management server Z is configured to accumulate device information (for example, abnormality information) of the devices 4 in each building A to D by receiving the notification signal Sh, and to transmit the device information to the remote monitoring base X. ing. The group management server Z also transmits device information of the devices 4 to an external terminal 6, which will be described later. Note that in this embodiment, the group management server Z is configured by a cloud server.

In this embodiment, the remote monitoring system 100 includes an external terminal 6. The external terminal 6 is a portable communication terminal, and may be carried by a worker outside the remote monitoring base X. As the external terminal 6, for example, a smartphone, a tablet terminal, a laptop computer, etc. are used.

In this embodiment, an external terminal 6 carried by a worker is connected to an Internet line N. The external terminal 6 is connected to the Internet line N via a wireless communication network such as a mobile phone communication network. For example, the external terminal 6 may be connected to an LTE (Long Term Evolution) line. The external terminal 6 is configured to receive information about the devices 4 stored in the group management server Z.

The remote monitoring base X is equipped with a base terminal 5. The base terminal 5 is connected to the base-side router Rx via a line within the base (for example, LAN: Local Area Network).

The remote monitoring base X includes a display monitor 50 and an operation section 53. In this embodiment, the display monitor 50 includes a first monitor 51 and a second monitor 52. The operation unit 53 includes a keyboard 53k and a mouse 53m. However, the configuration is not limited to this, and the remote monitoring base X may include a touch panel in which the display monitor 50 and the operation unit 53 are integrated.

As described above, each of the plurality of buildings A to D is equipped with a monitoring device 1 and a notification device 2, and various types of equipment 4 are installed in each of the buildings A to D.

Examples of the equipment 4 include power equipment, air conditioning equipment, and water supply and drainage sanitary equipment. The equipment 4 may also include representative alarms such as automatic fire alarm equipment and earthquake detectors, which are disaster prevention equipment.

The notification device 2 is configured to acquire device information from these plural types of devices 4 and to notify the device information. The notification device 2 acquires the setting state, operating state, abnormal state, etc. of various devices 4 as device information. To give an example of equipment information, for example, if the target equipment 4 is a substation equipment of electric power equipment, the equipment information will be power outage information due to a commercial power outage, and if the target equipment 4 is a cold source equipment of an air conditioning equipment, it will be information about a power outage due to a failure. An abnormal alarm for chilled water temperature becomes equipment information, and in the case of a water receiving tank for water supply and drainage sanitary equipment, a low water alarm becomes equipment information. In addition, information such as a signal from the automatic fire alarm equipment receiving the representative signal is considered as device information. In this embodiment, the notification device 2 is configured to notify of an abnormality in the equipment 4 in the building. The notification device 2 notifies, for example, power outage information due to a commercial power outage, an abnormal cold water temperature warning due to a failure of a cooling/heat source device, a water reduction warning for a water tank, etc., as described above.

The monitoring device 1 is a terminal for monitoring and managing (operating) the device 4 . The monitoring device 1 includes a monitoring monitor 10 on which the status of the equipment 4 is displayed. The surveillance monitor 10 is configured to display a surveillance image G, and the status of the device 4 is displayed on this surveillance image G. The monitoring device 1 also includes an operation section 13. By operating the operation unit 13, the worker can check the status of the device 4, control the device 4, etc., and deal with the problem. In this embodiment, the operation unit 13 includes a keyboard 13k and a mouse 13m. However, the configuration is not limited to this, and the monitoring device 1 may include a touch panel in which the monitoring monitor 10 and the operation unit 13 are integrated. The monitoring device 1 performs a monitoring function by receiving an abnormality alarm from the device 4. In addition, the monitoring device 1 can be operated by a worker to register the operation schedule of the air conditioning equipment belonging to the equipment 4 in each building A to D, and to check the operation of the emergency generator after receiving a power outage signal. It is configured.

As shown in FIG. 1, a remote monitoring base X and a notification device 2 are connected via an Internet line N and a group management server Z. Then, the notification signal Sh from the notification device 2 is transmitted to the remote monitoring base X via the group management server Z, so that the content of the notification is displayed on the display monitor 50 of the remote monitoring base X. That is, the content of the notification by the notification device 2 is transmitted to the remote monitoring base X via the group management server Z, and is received at the remote monitoring base X. Thereby, when the notification device 2 is making a notification in a target building (for example, "Building A"; the same applies hereinafter), the content of the notification can be grasped at the remote monitoring base X. For example, when the notification device 2 reports an abnormality in the device 4, the remote monitoring base X can recognize the abnormality. The notification device 2 is connected to the monitoring device 1 wirelessly or by wire. The notification device 2 may also be connected to each device 4. In this embodiment, the notification device 2 is connected to the building router Ra using the internal line (LAN) of the building A, and is also connected to the Internet line N via the building router Ra.

In this embodiment, the notification signal Sh by the notification device 2 is transmitted not only to the remote monitoring base X but also to the external terminal 6 via the group management server Z. Thereby, when the notification device 2 is making a notification in the target building A, the content of the notification can also be acquired by the external terminal 6. That is, the worker can grasp the status of the equipment 4 installed in the building A using the external terminal 6.

As described above, each of the plurality of buildings A to D is provided with the monitoring device 1. A remote control device 3 is connected to each of the plurality of monitoring devices 1. The remote control device 3 is connected to the monitoring device 1 so as to be able to remotely input an operation signal So for operating the monitoring device 1, and is configured to be able to obtain a display signal Si input to the monitoring monitor 10. Further, the remote control device 3 is connected to the remote monitoring base X via the Internet line N, and transmits the operation signal So from the remote monitoring base X to the monitoring device 1, and also transmits the acquired display signal Si to the remote monitoring base X. It is configured to send to site X. The operation signal So and the display signal Si are transmitted and received by the remote control device 3 between the monitoring device 1 and the remote monitoring base X without going through the group management server Z. That is, the transmission route of the operation signal So and the display signal Si is different from the transmission route of the notification signal Sh via the group management server Z. The remote control device 3 is connected to the monitoring device 1 (or the monitoring monitor 10) via a video cable, an audio cable, or the like. In this embodiment, the remote control device 3 is connected to the building router Ra using the internal line (LAN) of the building A, and is also connected to the Internet line N via the building router Ra. For example, as the remote control device 3, a so-called remote KVM, which is a KVM device (Keyboard, Video, Mouse) added with a network access function, can be used.

The notification contents by the notification device 2 are transmitted to the remote monitoring base X via the group management server Z, so that the notification contents are displayed on the display monitor 50 of the remote monitoring base X. In this embodiment, the content of the notification by the notification device 2 is displayed on the first monitor 51. In FIG. 1, the content of notification by the notification device 2 is schematically indicated by "△". Details of the notification content will be described later.

By operating the operation unit 53 of the remote monitoring base X based on the notification content displayed on the display monitor 50, the monitoring device 1 corresponding to the building A that is the notification source and the remote monitoring base X are connected to the remote control device 3. are connected so as to be able to transmit the operation signal So and the display signal Si. As a result, the monitoring image G displayed on the monitoring monitor 10 of the building A can be displayed on the display monitor 50 of the remote monitoring base X, and the monitoring device 1 can be remotely operated by the operation unit 53 of the remote monitoring base X. becomes. In FIG. 1, the surveillance image G displayed on the surveillance monitor 10 is schematically indicated by "☆". In this embodiment, the surveillance image G displayed on the surveillance monitor 10 is displayed on the second monitor 52. In other words, in the illustrated example, a monitoring image G similar to the monitoring image G displayed on the monitoring monitor 10 of the building A (indicated by "☆") is displayed on the second monitor 52 of the remote monitoring base X. has been done. Details regarding the monitoring image G will be described later.

In this manner, in the remote monitoring system 100 according to the present disclosure, when the notification device 2 is making a notification in any one of the buildings A to D, the content of the notification is transmitted remotely via the group management server Z. It is transmitted to the monitoring base X and the external terminal 6. Then, at the remote monitoring base X, information about the target building (for example, building A) in which the notification device 2 is installed is acquired together with the notification contents by the notification device 2. The content of the notification is displayed on the first monitor 51, and the surveillance image G of the surveillance monitor 10 of the target building A is displayed on the second monitor 52. At the remote monitoring base X, the monitoring device 1 of the target building A can be remotely operated using the operating unit 53.

In the above, with reference to FIG. ☆" will be displayed. On the other hand, FIG. 2 shows a specific example of the content displayed on the first monitor 51 and the second monitor 52.

As shown in FIG. 2, map information M indicating a plurality of buildings A to D is displayed on the display monitor 50 together with the notification contents from the notification device 2. In this embodiment, map information M is displayed on the first monitor 51. That is, both the notification content from the notification device 2 and the map information M are displayed on the first monitor 51. Note that the second monitor 52 displays the surveillance image G of the surveillance monitor 10 of the target building A. The monitoring image G displayed on the second monitor 52 is used to understand the specific circumstances of the device 4 that is the target of notification in the target building A, or to control the device 4 using the operation unit 53. used.

In this embodiment, the first monitor 51 includes a first display area F1 and a second display area F2. In the illustrated example, the content of the notification by the notification device 2 is displayed in the first display area F1. Map information M is displayed in the second display area F2. Note that it is preferable that operation icons or the like be displayed in areas other than the first display area F1 and the second display area F2 on the first monitor 51.

The content of the notification by the notification device 2 is the content indicating the status of the device 4. The notification content by the notification device 2 is displayed on the display monitor 50 of the remote monitoring base X (the first display area F1 of the first monitor 51 in this example) in the form of letters, graphics, symbols, or a combination thereof.

The notification content includes at least the name of the building (for example, building A) in which the notification device 2 that has notified the notification content is installed (see FIG. 2). In addition to this, the notification content may include the notification time, the type and identification information of the target device, the status of the target device, and the like. For example, the type and identification information of the target device include "cold/hot water heat source device", "model number α", etc., and these are displayed in the first display area F1 as notification contents. For example, the status of the target device includes "major failure", "minor failure", "abnormal stop", etc., and these are displayed in the first display area F1 as notification contents. In addition, in this embodiment, the notification content notified by the notification device 2 is accumulated in the group management server Z as history information. Thereby, the worker at the remote monitoring base X can easily search past notification contents, and display the search results on the display monitor 50 (in this example, the first display area F1 of the first monitor 51). I can do it.

In this embodiment, the map information M displays an area monitored and managed by the remote monitoring system 100 and a plurality of buildings A to D placed in the area. This makes it easy to visually grasp the positions of the plurality of buildings A to D on the map. In this embodiment, a plurality of buildings A to D monitored by the remote monitoring system 100 are displayed in association with railway and bus route maps. This allows the locations of each of the buildings A to D to be displayed in correspondence with stations and bus stops, making it easier to coordinate with transportation facilities in the event of an emergency.

In this embodiment, when the notification content is notified by the notification device 2, the building A related to the notification content is shown in the map information M in a manner to be distinguished from the other buildings B to D. For example, in the map information M, icons representing each of the buildings A to D are displayed, and normally, the icons are not distinguished from each other. However, only the icon indicating the target building (building A in this case) to which the notification device 2 has notified is displayed in a different color from the icons indicating other buildings B to D, displayed larger, or lit or blinking. In this way, the target building A and the other buildings B to D are shown in a distinguishable manner. This makes it possible to easily grasp the location of the target building A among the plurality of buildings A to D, to which the notification is being made.

By operating the operation unit 53, the monitoring image G of the monitoring monitor 10 in the target building A is displayed on the second monitor 52, and the monitoring device 1 in the target building A can be remotely operated. has been done. Specifically, the worker selects the target building A by operating the mouse 53m, aligning the pointer P with the icon of the target building A that is shown in a distinguishable manner in the map information M. Then, the surveillance image G of the surveillance monitor 10 of the selected target building A is displayed on the second monitor 52. The worker further operates the operating unit 53 as necessary to remotely control the monitoring device 1 in the target building A. The worker also directs other workers near the target building A (for example, a worker carrying the external terminal 6) to the site, as necessary.

The flow of the system described above is as shown in the flowchart shown in FIG. That is, as shown in FIG. 3, when an abnormality occurs in one of the plurality of buildings monitored by the remote monitoring system 100 (step #1), the notification device 2 of the target building where the abnormality has occurred issues a notification ( Step #2). The notification contents notified by the notification device 2 are displayed on the display monitor 50 of the remote monitoring base X (step #3). The worker at the remote monitoring base X selects the target building in the map information M on the display monitor 50 (step #4). As a result, the monitoring image G of the target building is displayed on the display monitor 50 of the remote monitoring base X (step #5). Thereafter, the worker at the remote monitoring base X grasps the specific circumstances of the equipment 4 in the target building based on the monitoring image G displayed on the display monitor 50. If the problem can be dealt with remotely, the equipment 4 is controlled by operating the operation unit 53, and if it is not possible, measures are taken such as sending another worker to the target building.

By introducing the remote monitoring system described above and monitoring at the remote monitoring base X, it becomes possible to rationalize human resources and produce economic effects, such as by consolidating night shift workers at the monitoring base.
