2. Description of the Related Art FIG. 7 is a block diagram of a conventional example and shows an example of a monitoring control system for monitoring an unmanned store in a financial system by using an ISDN network 15.

The terminal 13 in FIG. 7 is like an automatic transaction device such as an ATM or a terminal control device for controlling the automatic transaction device. The monitor control adapter 11 sends a command for monitor control from the console 10. The terminal 13 accepts and controls the terminal 13 and returns the control result, and at the same time, the console 10 is notified of an asynchronous event that has occurred in the terminal 13, for example, the occurrence of a failure.

The ISDN network 15 can receive a notification service of a sender identification number (address) at the time of call setup,
In this supervisory control system, in order to ensure security, in the supervisory control adapter 11, the console address 12 registered in advance is compared with the source address notified by the call setting, and if they do not match, the line connection is rejected, If they match, the line is connected in response to the network and the command from the console 10 is received.

On the other hand, when a failure or the like occurs in the terminal 13, the monitor control adapter 11 calls the registered console address destination and notifies the console 10 of the occurred event. The console 10 that received the control result response and event notification
Then, the content is displayed on an attached display device or the like and monitored by an observer.

[0006]

The monitor and control system described above has only one console. This is because monitoring and control are unified and security can be easily ensured. However, in recent years, ensuring system reliability,
With the diversification of operation modes, control of multiple consoles is required in the following cases.

Duplication of console (one is prepared as a standby machine and one is prepared for downtime) Multiple arrangements of monitoring locations (when monitoring locations on weekdays and holidays are different, such as from the operating form of the operator) Relocation of surveillance site (response during relocation such as relocation of surveillance center) When attempting to realize the operation of multiple consoles as described above, as shown in FIG.
Although connected to the network 15, the following inconveniences are conceivable for control between consoles.

When a plurality of consoles are connected at the same time and all commands / responses (responses) are released at the same time, this is the case when all commands from each console are accepted and an event is notified from the terminal device to the console. This is a method of notifying all consoles of the same information, but this results in complicated communication control, performance degradation, and line cost deterioration, as described below.

(Complexity of communication control) Since there are a plurality of communication partners, command management (command reception management according to the current state, priority control in case of collision, protection, etc.) and retry control in case of communication error etc. The state management for managing the state of is complicated.

(Degradation of Performance) It takes time because the same information must be constantly sent to a plurality of consoles. In addition, the frequency of line usage will increase.

(Deterioration of Operation Cost) As described above, since the frequency of line use increases, the operation cost also deteriorates. When using only one console at a time among multiple consoles with different installation positions, and switching and using when necessary When requesting communication from the terminal side to the console,
It is necessary to call using the console telephone number, but generally the address of each console is different (due to the location of the console), and if the console changes, the console address of the terminal side Need to be changed to the new console side. In this case, it is necessary to issue a command to notify each terminal device of a new console address or change the setting by manual operation at each terminal.

Since the newly switched console does not have the status information of each terminal, it is necessary to download the status information from the old console or issue a sense command (status notification request command) to all terminals. Becomes

In view of the above problems, it is an object of the present invention to provide a supervisory control system and a supervisory control adapter that easily realize unified monitoring / control in the case of having a plurality of consoles.

[0014]

In order to solve the above problems, a monitoring control system and a monitoring control adapter of the present invention are as follows: (1) First invention to be monitored A monitoring control system in which a device 4 and a master console 1 and a slave console 2 for monitoring and controlling the monitored device 4 are independently connected to a circuit switching network 3, and the slave console 2 is connected to the master console 1. The master console 1 sends a command to the monitored device 4, and the master console 1 issues to the monitored device 4 the command generated in the own console 1 and the command received from the slave console 2, and the command from the monitored device 4 is issued. Responds to and notifies the notified event to the slave console 2 in a unified manner. 4 constitute the events occurring asynchronously with responding to the command from the master console 1 as is to notify to the master console 1. (2) Second Invention In the first invention, the slave console 2 has the function of the master console 1, and the monitored device 4
Is configured so that, when an incoming call is directly received from the slave console 2, the console 2 is recognized as the master console 1 and a response to a command and an event notification are performed thereafter. (3) Third Invention In the above-mentioned first invention or second invention, the monitored device 4 has a holding means for holding all console addresses to which the respective priorities are assigned, When the abnormality of the master console 1 is detected by the communication of (1), the console address of the next order is set as the master console address and the event notification is performed. (4) Fourth Invention In the above-mentioned first invention, second invention, or third invention, when the monitored device 4 detects an abnormality in all the consoles, the monitored console 4 uses a predetermined initial console address as a master console address.

(7) Seventh invention In the sixth invention, when an abnormality is detected in all the consoles, a preset initial console address is set as a master console address, and then the subsequent processing is interrupted. .

[0015]

[Action]

(1) First Invention Each console issues a command to the monitored device 4 by using one of the plurality of consoles (master console) as a window, and the monitored device 4 does not respond to those commands. That is, the master console 1 is notified of the asynchronous event.

For this reason, the master console 1 centrally manages the information exchanged with the monitored device 4, and notifies each slave console 2 of the state of the monitored device 4 for unification.

As described above, since the master console 1 is used as a window for monitoring and control, it is possible to easily unify the monitoring information when the consoles are duplicated or when a plurality of consoles are simultaneously monitored and controlled, such as when the monitoring center is being relocated. It becomes possible to do. (2) Second invention In the above (1), the slave console 2 has the function of the master console 1. For example, when the power of the master console 1 is not turned on, the slave console 2 serves as a master console. Call the monitoring device 4 directly.

When the monitored device 4 receives an incoming call directly from the slave console 2, it recognizes the console as a master console and sends a response to the command and an event notification to the console.

As described above, when an abnormality occurs in the master console 1 or when the master console 1 is out of service due to a holiday or the like, an incoming call from the slave console 2 causes the monitored device 4 to operate the slave console 2 as a master slave. Since it is recognized as 1 and the event is notified to the console thereafter, unified management is achieved by the new console that has been switched. (3) Third invention When the master console 1 is notified of an asynchronous event from the monitored device 4, if an error has occurred in the master console 1, refer to console address holding means to which a priority order is assigned. Then, the console address of the next order of the current master console is set as the master console address and the event notification is performed.

As described above, the master console 1 can be switched from the monitored device 4 side, and unified management can be achieved. When initializing, the default (default setting) console address is used as the master console address. (4) Fourth invention In the third invention, when an abnormality is detected in all consoles, the monitored device 4 sets a predetermined initial console address as a master console address, and then interrupts the subsequent processing. To do.

As a result, the console address set (or the default value) at the time of initializing becomes the master console address at the time of restarting, and the plurality of monitored devices 4 can be unified. (5) Fifth Invention The present invention relates to a supervisory control adapter for a monitored device that communicates with a console. The supervisory control adapter is provided with all console address holding means 8 (see FIG. 1) for holding all console addresses permitted to accept commands, and the master switching means 5 receives the source console address and the held console address when receiving a call. Is compared, and if they match, the console address is set as the master console address thereafter. (6) Sixth Invention In the fifth invention of (5), the master switching means 8 is
When the abnormality of the current master console is detected, the master console address is switched to the console address of the next order based on the predetermined priority order (the current master console address setting means 7 stores the console address of the next order). (7) Seventh Invention When an abnormality is detected in all the consoles, the monitor control adapter sets the predetermined initial console address (the console address stored in the initial master console setting means 6) to the initial master console address. After setting in the setting means 7, the subsequent processing is interrupted.

As described above, the master console can be switched (switching of the control right of the console) mainly from a plurality of monitored devices by the same logic, and the control in the case where the monitoring information is centrally managed by one console is controlled. There is an effect that the right can be easily and surely switched.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 2 is a block diagram of an embodiment, FIG. 3 is a flow chart of a master console switching process by calling a slave console, FIG. 4 is an explanatory diagram of FIG. 3, and FIG. 5 is a flow chart of a command transmission process to a console. 6 is shown in FIG.
FIG. Note that the same reference numeral represents the same object throughout the drawings.

In this embodiment, the slave console monitors and controls the monitored device by using the master console as a window. At the time of start-up, the monitored device uses the predetermined default console address as the first master console address, When a command is received from another console, that console is used as the master console and the master console address is switched.When the monitored device detects an error in the current master console, the monitored device switches the console in the next order as the master console. When the console is abnormal, all the functions of the present invention are set to suspend the process by setting the first master console as the master console so that each monitored device sets the same console as the master console when restarting. Explain what you have .

In FIG. 2, a master console (console initially set as a master console) 20, a slave console 21, and a monitor control adapter 23 are connected to a public line network (ISDN network 15) and the master console 20
A command (down command) and a response (response, up command) are exchanged between the master console 20 and the slave console 21 by the ISDN network 15 separately. , An independent communication path is prepared.

In the master console 20, in addition to the commands input from its own console, the commands received from the slave console 21 via the ISDN network 15 are issued to the respective monitor control adapters 23, and the respective monitor control adapters 23 are also issued.
The response received from and the notified event information from I
Performs processing to send to the slave console 21 side via the SDN network 15.

As a result, the slave console 21 installed at another position can monitor and control each monitor control adapter 23 in the same manner as the master console 20, and the same terminal status information A is always supplied to each console. I will have. Therefore, unified management by the master console 20 is achieved.

Further, in this way, each monitor and control adapter 23 need only be aware of one console (master console 20), and even if an asynchronous event to be notified occurs, it can be ended with one notification.

Next, switching control of the master console in the monitor control adapter 23 will be described. In the supervisory control adapter 23 of FIG. 2, 24 is a network interface unit, which is an IS.
Call control based on the DN network 15 protocol is performed.

Reference numeral 28 is an initial master console address area (IM-AD area) in which a master console address initially set, here a default value, is stored. 29 is a master console address area (M-AD area) in which the current master console address is stored,
It is referred to by the network interface unit 24 as a call destination address. 26 is the entire console address area (S-AD area)
Console address CSL-A that can accept commands
D1 to CSL-ADn are stored in order of priority. Each of the above areas is secured in a non-volatile memory that is writable and erasable. Reference numeral 25 is a master switching unit, and by the processing described later, the master console address of the communication destination is M-
Store in AD area 29.

Reference numeral 30 denotes a supervisory control unit, which is a downlink command (monitoring,
Control), notification processing of the asynchronous event occurring in the terminal 32 to the master console 20, and the like. An interface unit 31 is an interface for exchanging data with the terminal 32 such as an automatic machine.

27 is a microprocessor unit MPU
Then, the above-mentioned respective parts constituted by the program are activated and run to perform the monitoring control operation. With the above configuration, the switching control of the master console on the monitor control adapter 23 side is performed as follows. 3 and 4 (1) At the start of operation, the monitor control adapter 23 first sets the default value of the master console in the IM-AD area 28 to the M-AD area 29 by the master switching unit 25, and then the command It will be in a waiting state. (2) If there is an incoming call in this state, the network interface unit 24 performs incoming call processing. That is, the destination address notified by the call setting is compared with the registered address in the S-AD area 26, and if the destination address is not the registered address, the line connection is rejected. (3) If it is a registered address, respond to the line connection and receive the command. As a result, the monitor control unit 30 executes the command. After returning the execution result, the line disconnection process is performed. (4) Then, the destination address of the incoming call and the M-AD area 29
Check whether the other party is the master console by comparing it with the master console address of. If it is not the master console as a result, the transmission source console address of the command received this time is registered in the M-AD area 29 as a new master console address.

As described above, the command from the console that matches the registered console address can be accepted, and if it is different from the master console address so far, the current console address is set as the master console address, and from the next event notification. Make a call using this address.

FIG. 4 illustrates the above contents. First, the terminals A to C are connected to the CSL as shown in FIG.
1 is recognized as the master console and the command is received.

When an abnormality occurs in the master console CSL1 in this state, the slave console CSL2 is switched as the master console, for example, by mutual contact of the operators. Then, as shown in (2) of FIG. 4, when a command is issued from the CSL2 to the terminal A, the terminal A receives and executes the command, and at the same time, the CSL2
As the new master console.

Then, as shown in (3) of FIG.
By issuing a command from terminal 2 to terminal B and terminal C, terminal B and terminal C also recognize the master console as CSL2.

As described above, when the slave console issues a command directly to the terminal, all the monitor control adapters 23 automatically switch the same console as the master console, and thereafter, the event notification from the terminal side becomes new. Will be sent to the master console CSL2. In addition, the slave console performs unified management as a master console by issuing a command.

Next, the master console switching process when the monitoring control adapter 23 gives an event notification will be described. 5 and 6 (1) The supervisory control adapter 23 stores the default console address in the M-AD area 29 and waits for a command. When an event such as a terminal error occurs, the monitoring controller 30
Creates transmission data, and (2) the network interface section 24 performs call processing to the master console address destination set in the M-AD area 29. (3) When there is a connection OK response from the network, the line is connected and the transmission data (command) is transmitted. When receiving the response to the command, the line is disconnected. (4) In the above (2), if there is no response from the line connection OK, the call processing is retried, and (5) If connection is not possible even after retrying a predetermined number of times, M-AD.
In area 29, the console address of the next priority is S-A
Store from D area 26 and call again. (6) Normally, the command can be sent by the process of (3), but if the line connection is not possible even if all consoles are called, the default console address is set in the M-AD area 29 and the process is interrupted ( WAIT state).

By this procedure, when the console is started up, all the monitor control adapters 23 recognize the default address as the master console and restart the process. Figure 6 shows the above pattern. Figure 6 (1) shows
First, a command is issued from the master console CSL1, and then, as shown in FIG. 6 (2), each terminal detects a failure in CSL1, and as shown in FIG.
An event is notified using L2 as a master console.

As described above, even when an error occurs in the master console and the command is not transmitted, the master console error is detected at the time of event notification, and the monitoring control adapter 23 side can switch to the normal console as the master console. .

As described above, when there are a plurality of consoles, the console side monitors and controls the terminal with one console as the window, and the terminal side uses the default console as the master console and when an abnormality is detected. By using the console of the next order as the master console, monitoring control is similarly performed using one console as a window, and unified management can be realized. For this reason,
Line cost reduction and communication congestion avoidance are achieved.

In the above description, the ISDN network which is easy to ensure security has been described, but it is needless to say that the present invention can be applied to a case where the ISDN network is connected to a public line such as a telephone line or a LAN.

[0043]

As described above, according to the present invention, in a supervisory control system in which a plurality of consoles supervises and controls a terminal via a circuit switching network, one console serves as a window, and the console side and the terminal side perform the same. Since I tried to switch,
Centralized management by the master console can be achieved without making the communication procedure particularly complicated, there is no performance degradation, and in the best communication cost, dual consoles, multiple monitoring locations, moving monitoring locations, etc. Has an effect that can be easily achieved.
