The operation (network network monitoring method) in the network monitoring system configured as described above will be described in detail below. (1) Site monitoring devices 2-1 to 2-n, proxy monitoring device 3-
First, in the following, the base monitoring devices 2-1 to 2-n and the proxy monitoring devices 3-1 to 3-n are in a 1: 1 ratio.
The operation in the case where the -1 to 2-n make a substitute request for monitoring to the substitute monitoring devices 3-1 to 3-n will be described with reference to FIG.

As shown in FIG. 8, for example, when the site monitoring device 2-1 transmits a request (trigger) for requesting the proxy monitoring device 3-1 to carry out the monitoring task, the central monitoring device 1 (step). S1), in the central monitoring device 1, after this request is received by the message receiving unit 42 of the receiving unit 4 and the fact is notified to the proxy state control unit 51 of the proxy control unit 5, the proxy state control unit 51 Substitution status management table 7
The flag “ON” is set in the corresponding area 1 (corresponding to the site monitoring device 2-1). This allows any of the site monitoring devices 2-1 to 2-n to monitor the proxy monitoring device 3-.
The proxy information indicating whether to substitute 1 is stored in the storage unit 7.

On the other hand, at this time, the proxy monitoring device 3-1 requests screen information necessary for proxy monitoring of the site monitoring device 2-1 in a certain fixed period (step S2). Base monitoring device 2 as a response to the request
All the information in the proxy status management table 71 together with the screen information of No. 1 are responded to the proxy monitoring device 3-1 through the information transmitting unit 8 as a part of the screen information (step S3).

In the proxy monitoring apparatus 3-1, the proxy information receiving section 31 receives the screen information and the information of the proxy status management table 71 responded by the central monitoring apparatus 1 (proxy information). Based on the proxy information, the proxy monitoring unit 32 determines which of the site monitoring devices 2-1 and 2-1.
Whether or not -n is making a proxy request, whether the flag set in the proxy state management table 71 is "ON" or "OF".
Confirmed by determining "F". As a result, now
Since the flag for the site monitoring device 2-1 is “ON” in the proxy state management table 71, the proxy monitoring unit 32 is performing a proxy indicating that the site monitoring device 2-1 is being monitored. Display control (lamp lighting, etc.) is performed (step S4).

At this time, the site monitoring device 2-1 also requests the central monitoring device 1 for the screen information necessary for monitoring in a certain fixed period (step S5). Similarly, the central monitoring device 1 sends the screen information to the screen information. At the same time, by receiving the proxy information of the proxy status management table 71 as a part of the screen information (step S6), the proxy monitoring device 3-1 is requesting the proxy monitoring device 3-1 to monitor itself (the site monitoring device 2-1). Display control is performed (step S7).

Thereafter, for example, the site monitoring device 2-1
When the central monitoring device 1 is requested (triggered) to release the monitoring work on behalf of the proxy monitoring device 3-1 (step S1 '),
In the central monitoring device 1, the reception canceling trigger is received by the receiving unit 4, and the proxy state control unit 51 applies the trigger in the proxy state management table 71 of the storage unit 7 (base monitoring device 2
-1) The proxy information is deleted by setting the area flag to "OFF".

Also in this case, the proxy monitoring device 3-1
Requests screen information necessary for proxy monitoring of the site monitoring device 2 at a certain fixed period (step S2 '), the proxy cancellation information in the proxy status management table 71 together with the screen information becomes a part of the screen information. In response to the proxy monitoring device 3-1 (step S3 '), the proxy monitoring unit 32 in the proxy monitoring device 3-1 based on the proxy cancellation information,
Which of the site monitoring devices 2-1 to 2-n is making the proxy cancellation request is confirmed by determining whether the flag set in the proxy status management table 71 is “ON” or “OFF”. It

As a result, if the flag corresponding to the site monitoring device 2-1 in the proxy status management table 71 is "OFF", the proxy monitoring unit 32 causes the site monitoring device 2-1.
The non-substitution display control (lamp extinguishing, etc.) indicating that the substituting of the substituting of the supervision is canceled is performed (step S4 '). At this time, the site monitoring device 2-1 also requests screen information necessary for monitoring at a certain fixed period (step S
5 '), similarly, by receiving the proxy cancellation information of the proxy status management table 71 together with the screen information from the central monitoring device 1 as a part of the screen information (step S6'), the self (site monitoring device 2-1) Non-proxy display control is performed to indicate that the monitoring proxy has been canceled (step S).
7 ').

Therefore, according to the above-mentioned network monitoring system, when the proxy monitoring devices 3-1 to 3-n execute the proxy monitoring, the proxy monitoring request (trigger) from the site monitoring device 2-1 Substitution status management table 7
By storing the proxy information in 1 (setting the flag “ON”), the proxy monitoring device 3-1 can perform monitoring on behalf of the user. It is not necessary to establish a shift work system for working on holidays, and it is possible to smoothly operate the monitoring work (especially the agency request) at each base without requiring personnel for performing the monitoring work.

When canceling the monitoring by the proxy monitoring devices 3-1 to 3-n, the site monitoring device 2-1 is used.
In response to a cancellation request from the agent (delegation cancellation trigger), the proxy information stored in the proxy status management table 71 is erased (the flag “OFF” is set) to cancel the proxy monitoring by the proxy monitoring device 3-1. Therefore, when it is no longer necessary to request a substitute, normal monitoring work can be easily returned to at any time.

Further, in the above-mentioned system, the proxy monitoring devices 3-1 to 3-n are configured as monitoring devices dedicated to the proxy provided separately from the site monitoring device 2-1. It only needs to function, maintenance and inspections can be performed at times other than when the agent is acting, and adjustments can be made so as not to cause failure on the agent's behalf. can do.

The proxy / cancellation operation between the other site monitoring devices 2-2 to 2-n and the proxy monitoring devices 3-2 to 3-n is performed in the same manner as described above. (2) Site monitoring devices 2-1 to 2-n, proxy monitoring device 3-
Substitute n: 1 between 1 to 3-n Next, in the following, the base monitoring device 2 is n: 1 between the base monitoring devices 2-1 to 2-n and the proxy monitoring devices 3-1 to 3-n.
The operation in the case where -1 to 2-n request the monitoring of the proxy monitoring devices 3-1 to 3-n will be described with reference to FIG.

As shown in FIG. 9, for example, the proxy monitoring device 3-1 issues a request (trigger) to the central monitoring device 1 for switching the proxy of monitoring work to the plurality of base monitoring devices 2-1 to 2-n. When transmitted (step S8), in the central monitoring device, this request is received by the message receiving unit 42 of the receiving unit 4, and the fact is notified to the proxy state control unit 51 of the proxy control unit 5, and then the proxy state control is performed. By the unit 51, the corresponding status of the proxy status management table 71 (a plurality of site monitoring devices 2-1
The flag "ON" is set in the area (corresponding to ~ 2-n). As a result, which of the site monitoring devices 2-1 to 2-
The proxy information indicating whether or not the proxy monitoring device 3-1 should monitor n is stored in the storage unit 7.

On the other hand, at this time, a plurality of site monitoring devices 2-1
2 to 2-n request screen information necessary for monitoring at a certain fixed period (step S9), and the central monitoring device 1 responds to the request by a plurality of site monitoring devices 2-1 to 2-1.
The 2-n screen information and the proxy information in the proxy status management table 71 are received as part of the screen information through the information transmission unit 8 (step S10).

Here, since the flag for each of the site monitoring devices 2-1 to 2-n is "ON" in the proxy status management table 71, each of them (the site monitoring devices 2-1 to 2-1) is turned on. 2-n) proxy monitoring device 3-
In-progress display control is performed to indicate that the request is being sent to 1 (step S11). At this time, the proxy monitoring device 3
-1 also requests screen information necessary for proxy monitoring of the site monitoring devices 2-1 to 2-n in a certain fixed period (step S
12) Similarly, in the central monitoring device 1, as a response to this request, all the information of the agency status management table 71 together with the screen information of the site monitoring devices 2-1 to 2-n is used as a part of the screen information and the information transmitting unit 8 is included. Through the proxy monitoring device 3-1 (step S13).

Further, in the proxy monitoring device 3-1, the proxy information receiving section 31 receives the screen information and the information (the proxy information) in the proxy status management table 71 responded by the central monitoring device 1 as described above. Based on the proxy information, the proxy monitoring unit 32 determines which site monitoring device 2-1 to 2-1.
2-n is making a proxy request, it is determined whether the flag set in the proxy status management table 71 is "ON" or "O".
It is confirmed by judging "FF". As a result,
Since the flags for the plurality of site monitoring devices 2-1 to 2-n are “ON” in the proxy status management table 71, the proxy monitoring unit 32 causes the plurality of site monitoring devices 2 to operate.
Substituting display control is performed to indicate that the monitoring of -1 to 2-n is performed (step S14).

After that, for example, the proxy monitoring device 3-1
When the central monitoring device 1 is requested (triggered) to cancel the proxy operation of the monitoring work with respect to the plurality of base monitoring devices 2-1 to 2-n (step S8 ′), the central monitoring device 1 receives the proxy cancellation trigger as the receiving unit 4 The proxy information is received by the proxy status control unit 51, and the proxy information is set by setting the flag of the corresponding (plurality of base monitoring devices 2-1 to 2-n) area in the proxy status management table 71 of the storage unit 7 to “OFF”. Is erased.

Also in this case, since the plurality of site monitoring devices 2-1 to 2-n request the screen information necessary for monitoring at a certain fixed period (step S9 '), the proxy information is displayed together with the screen information. The proxy cancellation information in the management table 71 is used as a part of the screen information, and a plurality of site monitoring devices 2-1 to 2-n
(Step S10 '), each site monitoring device 2-
In each of 1 to 2-n, non-proxy display control is performed to indicate that the monitoring of the self (the plurality of base monitoring devices 2-1 to 2-n) has been canceled (step S11 ').

At this time, the proxy monitoring device 3-1 also
The screen information required for the proxy monitoring of the plurality of site monitoring devices 2-1 to 2-n is requested at a certain fixed period (step S1).
2 '), similarly, the central monitoring device 1 responds to the proxy monitoring device 3-1 with the screen information and the proxy cancellation information of the proxy status management table 71 as part of the screen information (step S).
13 '), in the proxy monitoring device 3-1, information on the proxy status management table 71 (proxy cancellation information) responded by the central monitoring device 1 together with the screen information is received by the proxy information receiving unit 31, and the proxy cancellation information is received. Based on the
According to which of the base monitoring devices 2-1 to 2-n is making the proxy cancellation request, the proxy status management table 7
This is confirmed by determining whether the flag set in 1 is "ON" or "OFF".

As a result, the flags for the plurality of base monitoring devices 2-1 to 2-n in the proxy status management table 71 are "O".
If it is "FF", the proxy monitoring unit 32 performs non-proxy display control indicating that the proxy monitoring of the plurality of site monitoring devices 2-1 to 2-n has been canceled (step S1).
4 '). Therefore, according to the network network monitoring system described above, when executing the monitoring by the proxy monitoring devices 3-1 to 3-n, the proxy monitoring device 3-1 requests the proxy (proxy trigger) to perform the proxy status. Management table 7
By storing proxy information in 1 (setting the flag “ON”), the proxy monitoring device 3-1 collectively performs monitoring on behalf of a plurality of site monitoring devices 2-1 to 2-n. Therefore, in addition to the same advantages as those described above in item (1), the proxy operation for each base can be omitted, and the processing in the central monitoring device 1 can be simplified. It also contributes to the improvement of proxy processing capacity.

When canceling the monitoring by the proxy monitoring devices 3-1 to 3-n, the proxy monitoring device 3-1.
In response to a cancellation request (a proxy cancellation trigger) from the proxy status management table 71, the proxy information stored in the proxy status management table 71 is erased (a flag “OFF” is set), and a plurality of site monitoring devices 2-1 to 2-n On the other hand, since the proxy monitoring device 3-1 can collectively cancel the proxy monitoring, the same advantages as those described in the item (1) can be obtained, and the proxy cancellation for each site can be similarly performed. The operation can be omitted, the processing in the central monitoring device 1 can be simplified, and at the same time, it contributes to the improvement of the proxy processing capacity.

It should be noted that the proxy monitoring / monitoring of the plurality of site monitoring devices 2-1 to 2-n by the other proxy monitoring devices 3-2 to 3-n is performed.
The releasing operation is performed in the same manner as described above. (3) Switching Control of Proxy Monitoring Devices 3-1 to 3-n by Proxy Monitoring Device Switching Control Unit 51a Next, in the following, the site monitoring devices 2-1 to 2-n and the proxy monitoring devices 3-1 to 3-n. When the central monitoring device 1 receives the notification of the proxy switching instruction from the proxy monitoring devices 3-1 to 3-n during the interval n, it sends a proxy switching instruction to the monitoring of a certain site monitoring device 2-1 to 2-n. Informed proxy monitoring device 3-1 to 3-1
The operation when switching to 3-n will be described with reference to FIG.

In FIG. 10, reference numeral 51a indicates a proxy monitoring device switching control unit, and the proxy monitoring device switching control unit 51a is a proxy monitoring device 3-1 to 3-3.
When receiving the notification of the proxy switching instruction from -n, for example, the proxy monitoring of the base monitoring apparatus 2-1 is switched to the proxy monitoring apparatuses 3-1 to 3-n that have notified the proxy switching instruction, while When receiving the notice of the proxy switching cancellation instruction from the monitoring devices 3-1 to 3-n, the proxy monitoring of the site monitoring device 2-1 is canceled. Here, the proxy state control unit 51 shown in FIG. It is provided inside.

Then, for example, as shown in FIG. 10, a proxy switching instruction for monitoring the site monitoring device 2-1 is transmitted from the proxy monitoring device 3-1 to the proxy monitoring device switching control section 51a of the central monitoring device 1. Then, in the central monitoring device 1, the proxy monitoring device switching control unit 51a of the central monitoring device 1 performs proxy switching control so that the proxy monitoring device 3-1 performs the proxy of the site monitoring device 2-1 (step S15).

On the other hand, when the proxy monitoring device 3-2 sends a proxy switching command for monitoring the site monitoring device 2-1 to the proxy monitoring device switching control section 51a of the central monitoring device 1 (step S17), In the monitoring device 1, the proxy monitoring device switching control unit 51a performs proxy switching control so that the proxy monitoring device 3-2 acts on behalf of the site monitoring device 2-1 (step S18).

Next, as shown in FIG. 11, for example, while the proxy monitoring device 3-1 is acting for the monitoring of the site monitoring device 2-1 (step S19), the proxy monitoring device 3-1 switches from the central monitoring device 1 to the central monitoring device 1. When a proxy cancellation instruction of monitoring of the site monitoring device 2-1 is transmitted to the proxy monitoring device switching control unit 51a (step S20), the central monitoring device 1 causes the proxy monitoring device switching control unit 51a to monitor the site monitoring device. The proxy cancellation control is performed so that the proxy monitoring device 3-1 cancels the proxy 2-1 (step S21).

On the other hand, while the proxy monitoring device 3-2 is acting for monitoring the site monitoring device 2-1 (step S22), the proxy monitoring device 3-2 instructs the proxy monitoring device switching control section 51a of the central monitoring device 1 to operate. When an instruction to cancel monitoring on behalf of the site monitoring device 2-1 is transmitted (step S23), the central monitoring device 1
Then, the proxy monitoring device switching control unit 51a performs the proxy cancellation control so that the proxy monitoring device 3-2 cancels the proxy of the site monitoring device 2-1 (step S24).

Therefore, according to the above network monitoring system, when the proxy switching instruction is transmitted from the proxy monitoring devices 3-1 to 3-n to the central monitoring device 1, the site monitoring devices 2-1 to 2-n. Can be switched to the proxy monitoring devices 3-1 to 3-n for which the proxy switching instruction has been issued.
It becomes possible to promptly perform the proxy switching of the monitoring of the site monitoring devices 2-1 to 2-n in response to the proxy switching instruction from the proxy monitoring devices 3-1 to 3-n.

Further, when the proxy monitoring device 3-1 to 3-n sends a proxy cancellation instruction to the central monitoring device 1, the site monitoring devices 2-1 to 2-n can cancel the proxy. In response to a proxy cancellation instruction from the proxy monitoring devices 3-1 to 3-n, it is possible to quickly switch the monitoring proxy cancellation of the site monitoring devices 2-1 to 2-n. (4) Mutual backup control between the proxy monitoring devices 3-1 to 3-n Next, in the following, the proxy monitoring device between the site monitoring devices 2-1 to 2-n and the proxy monitoring devices 3-1 to 3-n. 3-1

Constantly monitors the proxy status of the proxy monitoring terminals 3-1 to 3-n, and when, for example, the proxy monitoring device 3-1 recognizes that the proxy monitoring device 3-1 cannot perform the proxy for some reason during the proxy, The proxy monitoring device switching unit 51b is activated so as to switch the proxy monitoring device 3-2 to the proxy monitoring device 3-2. The proxy monitoring device switching control unit 51b receives a proxy switching instruction notification from the proxy monitoring terminal monitoring unit 51c. Occasionally, a certain point monitoring device 2-1 which was performed by the proxy terminal devices 3-1 to 3-n
.. through 2-n are switched to the other proxy terminal devices 3-1 to 3-n, while the proxy terminal device 3-c receives the proxy switching cancellation instruction from the proxy monitoring terminal monitoring unit 51c. One site monitoring device 2 which was performed by 1 to 3-n
This is to cancel the substitution of -1 to 2-n.

Here, as shown in FIG. 12, for example, the proxy monitoring device 3-1 performs monitoring on behalf of the site monitoring device 2-1 (step S25), and the proxy-only terminal 3-2 operates as the site monitoring device 2. It is assumed that the monitoring of -2 is being performed (step S26). And at this time, the central monitoring device 1
Then, the proxy monitoring device monitoring unit 51c constantly monitors the proxy monitoring states of the proxy monitoring devices 3-1 and 3-2 (step S27). For example, the proxy monitoring device 3-1 cannot proxy for some reason. When the proxy monitoring device monitoring unit 51c recognizes that a failure has occurred, the proxy monitoring device monitoring unit 51c activates the proxy monitoring device switching control unit 51b to monitor the site monitoring device 2-1. The proxy monitoring device 3-1 is controlled to switch from the proxy monitoring device 3-1 to another proxy monitoring device 3-2 (step S28).

The switching control among the other proxy monitoring devices 3-3 to 3-n is also performed in the same manner as described above. in this way,
According to the above network monitoring system, the central monitoring device 1 monitors the proxy status of the regular monitoring devices 3-1 to 3-n by the proxy monitoring device monitoring unit 51c, and the proxy monitoring device 3-1. ~ 3-n becomes unable to act as a proxy due to a failure or the like, the proxy monitoring device switching control unit 51b can quickly switch the monitoring proxy to another proxy monitoring device 3-1 to 3-n. It is possible to continue the monitoring operation without hindering the monitoring of the monitoring devices 2-1 to 2-n.

(5) Multiple site monitoring devices 2-1 to 2-n
From a proxy monitoring device 3-1 to 3-n on a regular basis, next, in the following, a plurality of site monitoring devices 2-1 to 2-n perform proxy monitoring on behalf of monitoring at a pre-registered time. The operation when switching to the devices 3-1 to 3-n all at once will be described with reference to FIG.

In FIG. 13, the central monitoring device 1
The time monitoring unit 52a and the proxy flag setting unit 52b are provided in the time management unit 52 of the proxy control unit 5 shown in FIG. 3, and the time monitoring unit 52a monitors the current time with a timer or the like. Every time, when the current time reaches the proxy start time registered in advance in the scheduled proxy management table 72 (see FIGS. 3 and 5) of the storage unit 7, the proxy flag setting unit 52b.
While the notification is made to set the flag in the corresponding area in the proxy status management table 71 to "ON" (proxy notification), the time for canceling the pre-registered proxy request (proxy cancellation time) is reached. When it does, the proxy flag setting unit 5
2b is notified (release notification) to set the flag of the corresponding area in the proxy status management table 71 to "OFF".

Further, the proxy flag setting unit 52b sets the flag of the corresponding area in the proxy status management table 71 to "ON" by the proxy notification (the proxy trigger of the central monitoring device 1 itself) from the time monitoring unit 52a. Then, while the proxy information is stored, the flag of the corresponding area in the proxy status management table 71 is set to “OFF” by the cancellation notification (the cancellation trigger of the central monitoring device 1 itself) from the time monitoring unit 52b. The proxy information is deleted.

First, as shown in FIG. 13, the time monitoring unit 5
When the pre-registered proxy start time is detected by 2a, the time monitoring unit 52a causes the proxy flag setting unit 52b to
The proxy notification is sent to set the flag "ON" in the corresponding area in the proxy status management table 71 (step S29), and the proxy flag setting unit 5 that has received this proxy notification.
2b stores the proxy information in the storage unit 7 by setting the flag "ON" in the corresponding area in the proxy status management table 71 (step S30).

At this time, each site monitoring device 2-1 to 2-n
Requests screen information necessary for monitoring in a certain fixed period from the central monitoring device 1 (step S31), and the central monitoring device 1 responds to this request by monitoring each site monitoring device 2
In addition to the screen information of -1 to 2-n, the proxy information in the proxy status management table 71 is used as a part of the screen information, and the information transmitting unit 8
Through (step S32).

Now, in the proxy state management table 71, the flags for the site monitoring devices 2-1 to 2-n are "O".
Since it is “N”, self (base monitoring devices 2-1 to 2
-N) proxy display control is performed to indicate that the proxy monitoring device 3-1 is requesting the proxy monitoring (step S3).
3). At this time, the proxy monitoring device 3-1 also requests screen information necessary for proxy monitoring of the site monitoring devices 2-1 to 2-n in a certain fixed period (step S34), and similarly, the central monitoring is performed. In the device 1, as a response to this request, all the information of the proxy status management table 71 together with the screen information of the site monitoring devices 2-1 to 2-n is sent to the proxy monitoring device 3-1 through the information transmission unit 8 as a part of the screen information. It responds (step S35).

Further, in the proxy monitoring device 3-1, the proxy information receiving unit 31 receives the screen information and the information (the proxy information) of the proxy status management table 71 responded by the central monitoring device 1 as described above. Based on the proxy information, the proxy monitoring unit 32 determines which site monitoring device 2-1 to 2-1.
2-n is making a proxy request, it is determined whether the flag set in the proxy status management table 71 is "ON" or "O".
It is confirmed by judging "FF". As a result,
Now, in the proxy status management table 71, each site monitoring device 2
Since the flags for -1 to 2-n are "ON", the proxy monitoring unit 32 causes the base monitoring devices 2-1 to 2-1 to operate.
The proxy display control is performed to indicate that the monitoring of -n is being proxy (step S36).

After that, for example, when the pre-registered proxy cancellation time is detected by the time monitoring unit 52a, the time monitoring unit 52a causes the proxy flag setting unit 52b to flag the corresponding area in the proxy status management table 71. A cancellation notice is sent to set "OFF" (step S2).
9 '), the proxy flag setting unit 52b which has received the cancellation notice
Sets the flag "OFF" in the corresponding area in the proxy status management table 71 to erase the proxy information (step S30 ').

Also in this case, each site monitoring device 2-
Since 1 to 2-n request screen information necessary for monitoring at a certain fixed period (step S31 '), the proxy cancellation information in the proxy status management table 71 is used as a part of the screen information together with the screen information. Responding to the site monitoring devices 2-1 to 2-n (step S32 '), each site monitoring device 2-1 to 2-2.
-In (n), each (each site monitoring device 2-1 to 2-1)
The display control during non-substituting indicating that the substituting for monitoring in 2-n) has been canceled is performed (step S33 ').

At this time, the proxy monitoring device 3-1 also
The screen information necessary for the proxy monitoring of each site monitoring device 2-1 to 2-n is requested at a certain fixed period (step S3).
4 '), similarly, the central monitoring device 1 responds to the proxy monitoring device 3-1 with the screen information and the proxy cancellation information of the proxy status management table 71 as part of the screen information (step S).
35 '), in the proxy monitoring device 3-1, information on the proxy status management table 71 (proxy cancellation information) responded from the central monitoring device 1 together with the screen information is received by the proxy information receiving unit 31, and the proxy cancellation information is received. Based on the
According to which of the base monitoring devices 2-1 to 2-n is making the proxy cancellation request, the proxy status management table 7
This is confirmed by determining whether the flag set in 1 is "ON" or "OFF".

As a result, the flag for each of the site monitoring devices 2-1 to 2-n in the proxy status management table 71 is set to "OF".
If it is "F", the proxy monitoring unit 32 performs non-proxy display control indicating that the proxy monitoring of each of the site monitoring devices 2-1 to 2-n has been canceled (step S36 ').
Similarly, in the other proxy monitoring devices 3-2 to 3-n, the monitoring of the plurality of site monitoring devices 2-1 to 2-n can be performed simultaneously at a certain time.

As described above, according to the network network monitoring system described above, when the pre-registered proxy start time comes, the proxy notification of the time monitoring unit 52b (the proxy trigger of the central monitoring apparatus 1 itself) causes the storage unit 7 to store the data. By storing proxy information in the proxy status management table 71, monitoring of the site monitoring devices 2-1 to 2-n is performed by the corresponding proxy monitoring devices 3-1 to 3-n, while pre-registered proxy At the release time, the time monitoring unit 52b sends a release notification (a release trigger of the central monitoring device 1 itself) to erase the proxy information in the proxy status management table 71, and the corresponding site monitoring devices 2-1 to 2-n. Since the monitoring on behalf of the company will be canceled, for example, the replacement time of the monitoring work in each site is decided in advance to minimize the number of personnel required to carry out the monitoring work. Along with the kill, it is possible to perform the operation of the monitoring work extremely smoothly.

(6) On-time proxy request control for each site from each site monitoring device 2-1 to 2-n to the proxy monitoring device 3-1 to 3-n Next, hereinafter, a plurality of site monitoring devices 2- will be described. The operation of switching the proxy monitoring to the proxy monitoring devices 3-1 to 3-n when the time 1 to 2-n is registered in advance for each base will be described with reference to FIG.

Incidentally, in FIG. 14, the central monitoring device 1
The time monitoring unit 52a, the proxy flag setting unit 52d, and the on-time proxy reception unit 52c are respectively the proxy control unit 5 shown in FIG.
Provided in the time management unit 52 of the
a, when the proxy start time registered in advance in the scheduled proxy management table 72 of the storage unit 7 is reached, the proxy flag setting unit 52d sets the flag of the corresponding area in the proxy status management table 71 to "ON". Notify to do (substitute notification)
On the other hand, when the pre-registered delegation time comes,
The proxy state management table 71 is added to the proxy flag setting unit 52d.
The notification (release notification) is made so as to turn off the flag of the corresponding area within the area.

Further, the on-time agency reception unit 52c receives each agency start time from each of the site monitoring devices 2-1 to 2-n and sets the agency start time in the corresponding area of the on-time agency management table 72. , Each site monitoring device 2-
The proxy cancellation times are received from 1 to 2-n, and the proxy cancellation times are set in the corresponding areas of the scheduled proxy management table 72.

Further, the proxy flag setting unit 52d receives the proxy notification from the time monitoring unit 52a (the proxy trigger of the central monitoring device 1 itself), and the base monitoring device 2 for which the proxy start time is set in the scheduled proxy management table 72. The proxy information for -1 to 2-n is stored in the storage unit 7 by setting the flag of the corresponding area in the proxy state management table 71 to "ON", while the cancellation notification from the time monitoring unit 52a is performed. By the (trigger trigger of the central monitoring device 1 itself), the proxy information for the base monitoring devices 2-1 to 2-n for which the proxy cancellation time is set in the on-time proxy management table 72 is stored in the proxy status management table 71. Set the area flag to "OFF"
The setting is to be deleted from the storage unit 7.

Then, as shown in FIG. 14, in the central monitoring device 1, the time is based on the agency start time registered (set) in the on-time agency management table 72 through the on-time agency accepting unit 52c (step S37). The monitoring unit 52a sends a proxy notification to the proxy flag setting unit 52d when the proxy start time of a certain site monitoring device 2-1 to 2-n comes (step S38), and the current time and the scheduled proxy management table 7
The time information of 2 is compared (step S39), and if there is a match, the flag of the corresponding area in the agency status management table 71 is set to "ON" and the agency information is stored (step S40). .

For example, as shown in FIG. 14, the proxy time of the site monitoring apparatus 2-1 is "2" in the scheduled proxy management table 72.
0:00 ", the proxy start time of the site monitoring device 2-2 is" 2 "
When it is registered as “1:00”, when it becomes “20:00”, the time monitoring unit 52a transmits a proxy notification to the proxy flag setting unit 52d, and “20:00” and the time information of the scheduled proxy management table 72. And there is a match with 20:00 now, so the flag of the corresponding area in the proxy state detection table 71 is set to "ON" and the proxy information is stored. In addition, other base monitoring devices 2-1 to 2-n
Similarly, when the time (21:00, etc.) registered in advance in the on-time proxy management table 72 is reached, the same processing as described above is performed.

At this time, each base monitoring device 2-1
2 to n request screen information necessary for monitoring at a certain fixed period (step S41), and the central monitoring device 1
As a response to this request, a plurality of site monitoring devices 2-1
~ 2-n screen information and proxy status management table 71
The agency information in the above is received as a part of the screen information through the information transmitting unit 8 (step S42).

Now, in the proxy status management table,
The flag for each base monitoring device 2-1 to 2-n is "O.
N ”, each site monitoring device 2-1 to 2-n
Then, each of them (base monitoring devices 2-1 to 2-n)
The proxy display control is performed to indicate that the proxy monitoring device 3-1 is requesting the proxy monitoring (step S43).
At this time, the proxy monitoring device 3-1 also requests screen information necessary for proxy monitoring of each of the site monitoring devices 2-1 to 2-n in a certain fixed period (step S44), and similarly, the central portion In the monitoring device 1, as a response to this request, all the information of the proxy status management table 71 together with the screen information of each of the site monitoring devices 2-1 to 2-n is used as a part of the screen information through the information transmitting unit 8 through the proxy monitoring device 3-. 1 (step S45).

Further, in the proxy monitoring device 3-1, the proxy information receiving section 31 receives the screen information and the information (the proxy information) of the proxy status management table 71 responded by the central monitoring device 1 as described above. Based on the proxy information, the proxy monitoring unit 32 determines which site monitoring device 2-1 to 2-1.
2-n is making a proxy request, it is determined whether the flag set in the proxy status management table 71 is "ON" or "O".
It is confirmed by judging "FF". As a result,
Since the flags for the plurality of site monitoring devices 2-1 to 2-n are “ON” in the proxy status management table 71, the proxy monitoring unit 32 causes the plurality of site monitoring devices 2 to operate.
Substituting display control is performed to indicate that the monitoring of -1 to 2-n is performed (step S46).

Thereafter, for example, in the central monitoring device 1, the scheduled agency management table 72 is passed through the scheduled agency receiving section 52c.
On the basis of the proxy cancellation time registered (set) therein (step S37 '), when the time monitoring unit 52a reaches the proxy cancellation time of a certain site monitoring device 2-1 to 2-n,
The proxy cancellation notification is transmitted to the proxy flag setting unit 52d (step S38 '), and the current time and the scheduled proxy management table 72 are displayed.
(Step S39 '), and if there is a match, the flag of the corresponding area in the proxy status management table 71 is set to "OFF" and the proxy information is erased (step S40'). ).

Also in this case, each site monitoring device 2-
Since 1 to 2-n request screen information necessary for monitoring at a certain fixed period (step S41 '), the proxy cancellation information in the proxy status management table 71 together with the screen information is used as a part of the screen information. Responding to the site monitoring devices 2-1 to 2-n (step S42 '), each site monitoring device 2-1 to 2-1.
-In (n), each (each site monitoring device 2-1 to 2-1)
The display control during non-substituting indicating that the substituting for monitoring in 2-n) has been canceled is performed (step S43 ').

At this time, the proxy monitoring device 3-1 also
The screen information required for monitoring each of the site monitoring devices 2-1 to 2-n is requested in a certain fixed period (step S44 '),
Similarly, the central monitoring device 1 responds to the proxy monitoring device 3-1 with the screen information and the proxy cancellation information of the proxy status management table 71 as part of the screen information (step S4).
5 '), in the proxy monitoring device 3-1, the proxy status management table 7 responded by the central monitoring device 1 together with the screen information.
1 information (delegation cancellation information) is received by the delegation information reception information 31, and based on this delegation cancellation information, the delegation monitoring unit 32 causes any of the site monitoring devices 2-1 to 2-n to make a delegation cancellation request. If the flag is set to "ON" or "OF" in the proxy status management table 71,
Confirmed by determining "F".

As a result, the flag for each of the site monitoring devices 2-1 to 2-n in the agency status management table 71 becomes "OF".
If it is "F", the proxy monitoring unit 32 performs non-proxy display control indicating that the proxy monitoring of each of the site monitoring devices 2-1 to 2-n has been canceled (step S46 ').
Therefore, according to the network monitoring system shown in FIG. 14, the proxy time can be registered for each site, and at the pre-registered proxy time, the site monitoring devices 2-1 to 2-n.
On the other hand, the proxy monitoring devices 3-1 to 3-n perform the proxy monitoring of the local monitoring devices 2-1 to 2-n at the pre-registered proxy cancellation time. Since the delegation is canceled, for example, it is possible to predetermine the replacement time of the monitoring work etc. tailored to each base and secure the minimum number of personnel to carry out the monitoring work,
It is possible to smoothly carry out the operation of monitoring work.

(7) Automatic Substitution Switching Control by Central Monitoring Device 1 Next, in the following, the site monitoring device 2-1 between the site monitoring devices 2-1 to 2-n and the proxy monitoring devices 3-1 to 3-n. ~
The operation in the case of automatically monitoring the substitute monitoring devices 3-1 to 3-n when the 2-n becomes unmonitorable due to a failure or the like will be described with reference to FIG.

First, for example, when the application or the like of the site monitoring device 2-1 is operating normally, the regular diagnostic information transmitting unit 21 of the site monitoring device 2-1 sends a message of the periodic diagnostic information at a certain fixed period. The data is transmitted to the central monitoring device 1 through the reception path 4-1.
The regular diagnostic information is received by the regular diagnostic information receiving unit 43 of the receiving unit 4.
It is received every fixed period.

Here, when the periodic diagnostic information from the regular diagnostic information transmitting section 21 is not received by the regular diagnostic information receiving section 43 for a certain time or longer due to some reason such as a failure of the site monitoring apparatus 2-1, the central monitoring apparatus 1 In the proxy state management table 71, the proxy status control unit 51 considers that the monitoring by the site monitoring apparatus 2-1 is impossible and, for example, the proxy monitoring apparatus 3-1 monitors the site monitoring apparatus 2-1. The flag “ON” is set in the area of the site monitoring device 2-1 to store the proxy information in the storage unit 7, and the proxy monitoring device 3-1 as the proxy destination information in the proxy destination registration table 73 through the information processing unit 6. To set.

Then, in the central monitoring device 1, the monitoring information receiving section 41 receives the monitoring information about the site monitoring device 2-1 and this monitoring information is transferred to the proxy destination registration table 7
Based on the proxy destination information registered in 3, the information processing unit 6 registers (stores) it in the storage area of the monitoring information for the proxy monitoring device 3-1 in the monitoring information management table 74.

After that, the proxy status control unit 51 sends the information sending unit 8 to the proxy monitoring device 3-1 to monitor the management information table 7.
4 requests that the monitoring information of the site monitoring device 2-1 registered in the storage area for the proxy monitoring device 3-1 in 4 be transmitted, and the information transmitting unit 8 receives this request and receives the relevant monitoring information. Through the information transmission path 8'-1 to the proxy monitoring device 3-1 which is the proxy destination of the site monitoring device 2-1. As a result, the proxy monitoring device 3-1 performs the monitoring of the site monitoring device 2-1.

On the other hand, while the substitute monitoring device 3-1 is acting as a substitute for the monitoring of the base monitoring device 2-1, the fault of the base monitoring device 2-1 is recovered, and the periodical diagnostic information transmission unit 21 again performs the periodical monitoring. Transmission of diagnostic information is started, and this is the central monitoring device 1.
When it is received by the regular diagnostic information receiving unit 43, the proxy monitoring unit 1 of the central monitoring apparatus 1 sets a flag “OFF” in the area of the site monitoring apparatus 2-1 in the proxy status management table 71. The proxy information is deleted from the storage unit 7, and the proxy destination information (the proxy monitoring device 3-1) in the proxy destination registration table 73 and the monitoring information in the monitoring information management table 74 are deleted.

At this time, the monitoring information receiving section 41 provided in the receiving section 4 of the central monitoring apparatus 1 starts to receive the monitoring information together with the periodic diagnosis information from the site monitoring apparatus 2-1. Based on the status of the proxy information registered in the proxy status management table 71 by the status control unit 51 and the proxy destination information registered in the proxy destination registration table 73, it is determined that the site monitoring device 2-1 is not making a proxy request. Therefore, it is not transmitted to the proxy monitoring device 3-1 which was the proxy destination of the site monitoring device 2-1 (not stored in the monitoring information management table 74), but is transmitted to the site monitoring device 2-1. As a result, the proxy monitoring work by the proxy monitoring device 3-1 is canceled.

The other base monitoring devices 2-2 to 2-n,
The proxy / cancellation operation between the proxy monitoring devices 3-2 to 3-n is similarly performed. As described above, according to the above-described network monitoring system, when the central monitoring device 1 cannot receive the periodic diagnosis information from a certain base monitoring device 2-1 to 2-n for a certain time or longer (base monitoring device 2-1). ~ 2-n cannot be monitored), the site monitoring devices 2-1 to 2-n
Can be automatically delegated to any of the proxy monitoring devices 3-1 to 3-n.
Even when the monitoring work cannot be performed due to a failure or the like of -1 to 2-n, the monitoring work can always be performed by the proxy monitoring devices 3-1 to 3-n.

(8) Central monitoring device 1, base monitoring device 2-
1-2-n and the synchronous / asynchronous control on the common (same) monitoring screen of the proxy monitoring devices 3-1 to 3-n First, the change of a certain monitoring location is monitored by the central monitoring device 1 and the site monitoring devices 2-1 to 2-. n and the proxy monitoring devices 3-1 to 3-n will be described with reference to FIG.

Here, as shown in FIG. 16, the central monitoring device 1 stores in the storage unit 7 the above-mentioned table proxy state management table 71, scheduled proxy management table 72, proxy destination registration table 73 and monitoring information management. In addition to the table 74, a screen number table 75 is provided. In the screen number table 75, the same screen can be displayed on any of the site monitoring devices 2-1 to 2-n and the proxy monitoring devices 3-1 to 3-n. ,
It is possible to display different screens.

Here, for example, the screen having the screen number 2 in the screen number table 75 is commonly displayed (monitored) by the proxy monitoring device 3-1, the site monitoring device 2-1 and the site monitoring device 2-2. While watching, there is a monitoring point (here A)
When an abnormality occurs in the screen number table 75, the flag indicating the flicker (flashing) of the A lamp is set to “ON” in the area of the screen number 2 in the screen number table 75, and as a result, the common monitoring screen of the screen number 2 is monitored. Surrogate monitoring device 3-
