[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring device used in a system for monitoring the operating status of a digital exchange, a computer for information processing and the like.

[0002]

2. Description of the Related Art Conventionally, a remote monitoring system has been operated for monitoring the operating status of a digital exchange, a computer for information processing, etc. not only from the installation location but from a remote location through a communication line. FIG. 18 is a block diagram showing an example of this type of system. In the figure, this remote monitoring system includes a digital exchange 11 as a monitored device.
Control device (MA) 12 provided as an accessory to a, system console (SC) 13 as a monitoring device, and remote system console 14 (MC) as a remote monitoring device
It has and. The control device 12 includes, for example, RS-23.
A plurality of communication ports 12a to 12 using the 2C port
d are provided, and these communication ports 12a to 1 are provided.
The digital exchange 11a is connected between the ports 12a and 12d of the 2d, and the system console 13 is connected to the port 12b. Communication port 12
A modem 16a for communicating with the remote system console 14 is connected to c. A modem is also provided on the side of the remote system console 14, and the remote system console 14 has these modems 16a and 16a.
b, 16c through the public line network 15 to the control device 12
Connected to.

The system console 13 includes a personal computer 13a having a display 13c and a keyboard 13d and a printer 13b, and collects log data of the monitored device at regular intervals by starting a timer. That is, the system console 13 starts an automatic line connection operation to the digital exchange 11a at a predetermined time, sends a command for collecting log data stored in advance when the line is connected, and then executes this command. Then, the log data returned from the digital exchange 11a is received. When the end of this reception log data is confirmed, the next command is sent. Thereafter, similarly, necessary commands are sent in order, and correspondingly, the log data returned from the digital exchange 11a is sequentially received and collected.

In addition, when a monitor placed on the system console 13 arbitrarily collects log data of the digital exchange 11a, the monitor first receives the keyboard 13.
The console 13 and the digital exchange 11 are operated by the operation of d.
Instructing the line connection with a, the operation mode of the console 13 is set to the command reply mode. The command reply mode is a mode for setting parameters, receiving log data, and the like, and parameters such as the ID number of the control device 12, the destination telephone number, and the type of monitored device are set. Then, in this state, the monitor sends an arbitrary log data collection command to the keyboard 13
Input from d, and this sends this command to the digital exchange 11a. Therefore, log data is returned from the digital exchange 11a, and desired log data can be collected.

On the other hand, a remote system console 1 at a remote place
4 also includes a personal computer 14a having a display 14c and a keyboard 14d and a printer 14b. When collecting the log data of the digital computer 11a, the system console 13 is used.
Similarly, the log data of the monitored device is automatically collected according to a preset procedure at regular time intervals. The remote system console 14 is provided with an automatic line connection function for automatically collecting the log data, and by this function, control such as automatic call to the public line network 15, transmission of a dial signal and reception of a response is performed. The connection of the communication line with the monitoring device is controlled. Also in this remote system console 14, the supervisor can input a command from the keyboard 14d while connecting to the digital exchange 11a via a communication line and setting the command reply mode. It is possible to obtain log data of.

[0006]

However, the system console 13 and the remote system console 14 used in such a conventional system have a series of predetermined controls when collecting log data of the digital exchange 11a. Function to collect the log data determined by periodically executing the timer, or to obtain the desired log data by manually inputting a desired command with a keyboard by a supervisor and sending it to the digital exchange 11a. I only have.

Therefore, when collecting any log data from the remote system console 14 at any time, the monitoring person uses the latter function to instruct the line connection operation and obtain the desired monitored data. After connecting the line to the device, the command must be manually input from the keyboard and sent. However, the command to be input must be changed each time depending on the time, the operation mode (system) of the monitored device, the version, and the like, and one command is usually composed of 20 to 30 characters. Therefore, much time and labor are required for command input operation, resulting in poor collection efficiency and a heavy burden on the monitor.
Further, since 20 to 30 characters must be input for each command, erroneous input is likely to occur, and as a result, log data may not be collected correctly, which is not preferable.

The present invention has been made in view of the above circumstances, and an object thereof is to simplify the command input operation when arbitrarily collecting the monitoring information, thereby accurately and quickly collecting the monitoring information. It is to provide a monitoring device capable of collecting.

[0009]

In order to achieve the above object, the present invention is provided with a storage means for storing a plurality of command information necessary for collecting monitoring information in advance, and a command according to a predetermined mode designating operation. Mode setting control means for setting the optional mode is provided. Then, in the state in which the command arbitrary transmission mode is set, a plurality of command information stored in the storage means is selectively displayed, and a predetermined command designating operation is performed on the displayed command information. When performed, the corresponding command information is selectively transmitted to the monitored device, and the monitoring information returned from the monitored device in response to the transmitted command information is received. ..

According to another aspect of the present invention, a plurality of command information stored in the storage means is selectively displayed in a state where the command arbitrary selection mode is set, and predetermined command information corresponding to the displayed command information is displayed. It is also characterized in that the command information corresponding to the change input operation is partially changed and the changed command information is sent to the monitored device.

[0011]

As a result, according to the present invention, when a monitor arbitrarily collects monitoring information, a command arbitrary selection mode is set to selectively display a plurality of command information stored in advance. When the desired command information being displayed is selected and specified in this state, this command information is sent to the monitored device via the communication line.
Therefore, the observer only needs to select and specify desired command information, and does not need to manually input all the digits of the command information. Therefore, the time required to send a command when arbitrarily collecting the monitoring information is greatly reduced, and there is no fear of erroneous input. Therefore, the efficiency of collecting the monitoring information is improved and the burden on the monitor is reduced. Also, it becomes possible to always send an accurate command. These effects can be achieved especially in a remote monitoring device that remotely monitors via a communication line including a communication network, and can reduce the occupied time of the communication line to effectively use the line and save costs. It is very effective.

Further, it is possible to partially change the command information by performing a predetermined change input operation on the command information being displayed. Therefore, even when command information that is not stored in the storage unit is needed, new command information can be created relatively easily based on existing similar command information, and new command information can be created. When required, the time required to input and send a command can be shortened and the operation can be simplified as compared with the case where all the digits of command information must be input each time.

It has a DIP switch that switches the voltage source inside or outside. The alarm contact input signal is a current signal corresponding to ON or OFF of the failure notification contact of the monitored device, and its power source is the DC voltage source on either the contact side (external) or the DI interface 36 side. In addition to the relay contact, the fault notification contact includes the secondary output of the photocoupler. In this embodiment, there are four fault signals corresponding to the digital exchanges 11a to 11d which are the monitored devices.
, 8 other inputs are available, 1 of these 8
It can also be used to signal the fan stop of the controller 120.

The control contact output circuit 37 turns on / off the contact output of the output according to an instruction (key operation) from the system console 13 and the remote system console 140, and controls an arbitrary device by remote operation (power on / off). OFF and switch signal input) are possible. The control contact output signal is a latch-type momentary output that can be selected from normally open / normally closed.

With the above configuration, the control device 120 detects fault information from the digital exchanges 11a to 11d, which are monitored devices, and sends it to the system console 13 and the remote system console 140. The name of this fault signal is determined by registration from the remote system console 140 and the system console 13, and is managed for each ID number. Further, the control device 120 includes a plurality of ID numbers and a telephone number to be notified, a type (T, M, B) of the monitored device corresponding to the device connection port, a console message collection flag, and an alarm message collection flag ( (Comparison character string) and are registered respectively.

Further, the control device 120 determines the processing of the received data according to the type of monitored device and various flags. For example, when the type of monitored device is M, an alarm message sent from this device M is picked up from the corresponding port. This warning message is sent by adding a command to the text sent from the monitored device side.

Details of the alert message text of device M are shown in FIG. By setting the parameters in the control device 120, the device M monitors the data input to the designated port. A command portion and an extension portion are added to the text output from the device M, and the text is transmitted to the remote system console 140 and the system console 13. The command part includes an opening flag (SOH), a mode, a parameter, and an NMAID.

Of these, the mode is a code of various control requests, and a unique code is defined for each command mode. As an example thereof, a connection / disconnection / termination request from the system console 13 to each port, each similar request from the remote system console 140, and a control device 120 from the remote system console 140.

D is an identification number given to each control device.

On the other hand, the extension part is allocated for various data and messages. Undefined data such as setting parameters and console messages are assigned here. The ending flag (ETX) indicates the end of the text, that is, a packet delimiter.

The opening flag STX and the ending flag ETX in the alarm message sent from each monitored device are removed by the control device 120 and inserted into the extension section. During the command reply, the control device 120 monitors the alarm message and transmits the XOFF code to the device M after three alarm messages are received. Then, the control device 120 transmits the XON code to the device M after the transmission of the device warning message is completed, and subsequently performs the flow control.

Details of the alert message text from device B are shown in FIG. 3 (b). The character string in the autonomous message output from the device B is compared with the comparison character string by the control device 120, and when it is recognized as an alarm message to be issued to the system console 13 and the remote system console 140, this character string is detected. Autonomous messages are published as text. FIG. 3C is an example of this comparison character string, and shows the alarm rank, the alarm location, and the factor classification. For example, in the case of "MCPU /", when "MCPU" is included in the autonomous message, it is recognized as a message to be issued. The controller 120 can receive up to three alert messages and the remote system console 14
If 4 or more consecutive occurrences occur after the call to 0 is completed, 4
Discard after the first item. The control device 120 has a flag indicating whether or not console messages are accumulated in each port. One message has a unit of 80 bytes, and 90 messages are automatically reported. When the number exceeds 100, discard the oldest ones. When the transmission of the console message is started, the XOFF code is transmitted to the device B, and after the transmission is completed, the XON code is transmitted to control the data flow.

At the time of reporting the contact information and the alarm message, the control device 120 also transmits the contents of the console buffer (console message). For devices T and M, console messages are not stored. The communication procedure is divided into packets of 80 bytes and the ACK / NAK method is used. If all ports fail simultaneously, DI1
~ DI12, alarm message, console message ports 1 to 4 are processed in this order. The failure that occurred during the connection is
Notify the master remote system console as is, and notify the slave after disconnecting it.

In the fault log collection command, the command is set in the automatic log command file, and the fault log collection flag and the automatic log command start line and end line are set in the site management. When a failure occurs with the failure log collection flag set to Y, the remote system console 140 is automatically connected to the monitored device side and the failure log is collected.
When the system console 13 is connected to the monitored device, it is retried after 10 minutes. When the modem 16a of the controller 120 is busy, it is retried every 10 minutes. When a large number of monitored devices become faulty at the same time, the fault log data up to 20 are stored in the control device 120, and these fault log data are collected by the remote system console 140 in the order of occurrence. When a failure occurs again in the same monitored device, it is not stored twice when it has not been collected. The collected data is the printer 14b
Is output from. The network map displays failure information in an easy-to-understand manner by displaying failure information on the network. Graphic information consists of lines and boxes, and specifies coordinates and colors. A display character and a color are designated for the ID number of the control device 120 and the failure information of the contact input. The display method is a batch process for searching the failure information file. The hard copy is output from the printer 14b.

The information message exchange is performed by exchanging electronic messages between the system console 13 and the remote system console 140. The information message is managed on a screen-by-screen basis by a title and a 15-line message. The electronic message includes a standard electronic message, a trouble ticket electronic message, a received electronic message, and an arbitrary electronic message for transmission. It can be sent even while the other party is replying to a command. In this case, the recipient and the title are displayed in green on the 25th line when receiving, and the buzzer 14e is displayed.

Display and select the destination and title list. When sending the telegram of 15 lines, the non-input lines are not sent to reduce the communication time. It has a copy function when newly created, and simplifies key input. The data is divided into packets of 80 bytes each, and ACK / NAK is confirmed and transmitted. Send with a sequence number for each title and line, and edit on the receiving side. Since the command format is SOH to ETX of 15 lines, it can be transmitted even while the other party replies the command.

The port (monitored device, modem, system console) interface of the control device 120 is RS-
232C compliant, CCITT communication standard V. 24 compliant, C
I signal can be received. Baud rate is 1200, 24
00, 4800, 9600 bps are selected and set by the DIP switch.

The contents of the status display of the control device 120 include
Communication on / off display of the system console 13, failure occurrence display during communication between the system console 13 and each monitored device, remote system console 140 and each monitored device 1
There is an on / off display of communication with 1a to 11d and a display of whether or not a failure has occurred in each of the monitored devices 11a to 11d.

By the way, the remote system console 140
, A plurality of commands necessary for arbitrarily collecting log data are registered in advance, and these commands are named as a group. Then, a command group is selectively read from the storage unit by this name and displayed on the display 14c. When a command line is specified in this state, the command to be executed is specified. Further, by inputting change data from the keyboard 14d before execution, the command character string can be changed, deleted, or added.

Next, in the system configured as described above, the operation when the remote system console 140 arbitrarily collects log data from the monitored devices 11a to 11d will be described according to the control procedure of the CPU 410.
12 to 15 are flowcharts showing the control procedure and control contents.

In the standby state, the CPU 410 of the remote system console 140 displays the function menu on the display 14c in step 901. In this state, when the observer operates the keyboard 14d to input a log data collection request, the CPU 410 causes the step 90 to proceed.
In step 2, the request is detected and the process proceeds to step 903, and in step 903, a screen for prompting the input of the connection destination is displayed on the display 14c. According to the contents displayed on this screen, when the supervisor inputs the predetermined information regarding the connection destination, that is, the ID number of the digital exchange from the keyboard 14d, the CPU 410 makes steps 904 to 90.
5, the automatic line connection control is executed based on the information about the connection destination. As a result, first, the control device 120 is connected via the public line network 15,
Then, the control device 120 is connected to the target digital exchange. Then, when the line connection is completed, the CPU 410 displays the command reply screen on the display 14c in step 906. The command reply screen is a screen for displaying the log data sent from the monitored device, and a message for prompting the input of the login name / password is also displayed on this screen. The login name and password are information for arbitrarily designating a mode for collecting log data.

Now, in this state, it is assumed that an observer inputs a login name / password from the keyboard 14d in order to collect arbitrary log data. Then,
The CPU 410 proceeds to step 907 to enter the login name /
The input of the password is detected, and in step 908, the command execution screen is displayed on the display 14c. An example of this command execution screen is shown in FIG. Here, when the observer designates a desired execution command with a cursor or the like while looking at the command execution screen, the CPU 410 detects this designation in step 909, and displays the command on the display 14b.
Display the log command line specification / change screen on. FIG. 17
Shows an example of the screen. When the observer specifies the line number of the execution start command and inputs the command transmission instruction while looking at the log command line designation / change screen, the CPU 410 detects these inputs in step 910 and step 913, 91
4, the command designated above is sent to the digital exchange, which is the monitored device. That is, a desired command can be sent out only by selectively designating the command being displayed with the cursor.

On the other hand, when a command change input is made after the line number of the execution start command is specified, the CPU 41
0 detects this at step 911 and shifts to step 912, where the content of the command is partially changed to the content input from the keyboard 14d. Then, when a command transmission instruction is input in this state, the partially changed command is transmitted to the digital exchange which is the monitored device in step 914. That is, even when the command to be sent is not displayed on the screen, the desired command can be sent by only changing a part of the similar command being displayed.

Upon receiving the command sent from the remote system console 140, the digital exchange 11a generates log data corresponding to this command and sends it to the remote system console 140. When the CPU 410 of the remote system console 140 receives the log data in step 915, the CPU 410 proceeds to step 916. Then, when a screen switching instruction is input from the keyboard 14d in step 916, the process proceeds to step 917, in which the display screen of the display 14c is switched from the command execution screen to the command reply screen, and the above-mentioned reception is received on the command reply screen. The log data that has been displayed. Further, in this state, the CPU 410 determines the output destination of the log data in step 918, and when the flexible disk is designated as the output destination, the CPU 410 determines in step 91.
At 9, the log data is supplied to the FDD 501 and stored therein. When the printer 14b is designated as the output destination, the log data is supplied to the printer 14b and printed out in step 920.

On the other hand, when it is desired to send a new command that has not been registered in advance, the following procedure is performed. That is, while the command reply screen is displayed on the display 14c, the surveillance staff manually inputs a command from the keyboard 14d. Then, the CPU 410 detects the input of the above command in step 921 and proceeds to step 922, in which the above input command is sent to the digital exchange which is the monitored device. Thus, a completely new unregistered command is transmitted. When the sending of the command is completed, the CPU 410 monitors the return of the log data in step 923, and when the log data is sent from the digital exchange in this state, the log data is received and displayed on the display 14c as it is.

When a screen switching instruction is input in step 924 in this state, CPU 410 causes step 925.
Returns the display screen of the display 14c to the command execution screen. At this time, the observer specifies the execution start command line in step 926, but since the cursor on the screen is moved to the command line next to the command with the specified line number, the observer has to change the command. It is sufficient to omit the specification of the execution start command line and directly input the command transmission instruction. When this command transmission instruction is detected in step 929, the CPU 410 subsequently transmits the above command to the digital exchange in step 930.

On the other hand, when the observer operates the cursor to specify another command line when the execution start command line is specified, the CPU 410 makes this specification in step 92.
If it is detected here, the process proceeds to step 928, and if it is changed here, the content of the command is partially changed in step 928. Then, the process shifts to step 929 to send out the changed command. When the sending of the command is completed, the CPU 410 monitors the return of the log data in step 931. When the log data is sent from the digital exchange in this state, the CPU 410 receives the log data. The reception log data is displayed when the display screen of the display 14c is switched to the command reply screen.

Then, when collection of the necessary log data is completed and the monitor inputs the log off from the keyboard 14d, the CPU 410 detects the log off input in step 932 and shifts to step 933. Here, control for disconnecting the communication line connecting between the digital exchange and the control device 120 is executed. Then, after disconnecting the line, the reception log data is stored in step 934. At this time, step 935 and step 9
When the data re-output instruction and the file name are input from the keyboard 14d at 36, the CPU 410 proceeds to step 93.
In step 7, the output destination of the data is determined. If the output destination is the printer, the log data is output to the printer 14b in step 938.
To print out. If the data output destination is the display 14c, the CPU 410 executes step 93.
In step 9, the log data is output and displayed on the display 14c. In this state, when the observer inputs an instruction to end the log collection in step 940, the CPU 410 executes step 9
At 41, the display 14ck display screen is returned to the menu screen and the log collection is completed.

As described above, according to this embodiment, the remote system console 140 preliminarily stores in the ROM 415 or RAM 4 a plurality of log collection commands expected to be used.
When the log is registered in No. 16 and the log is arbitrarily collected in addition to the regular log collection, the previously registered log collection command is displayed on the display 14c, and the necessary command is displayed on the display 14c. By designating the desired command to be sent to the monitored device, the monitoring staff does not have to input all the digits of the log collection command from the keyboard 14d each time.
As a result, it is possible to collect arbitrary logs in a short time and accurately with a simple operation.

Further, since a part of the registered command can be changed by the keyboard 14d, even if the desired command is not registered in advance, a part of the registered similar commands can be modified. The desired command can be sent by simply doing this. Therefore,
In this case as well, it is not necessary to input all the digits of the command from the keyboard 14d, whereby the operation can be simplified and the log can be collected accurately in a short time.

Further, since the position of the cursor for designating the execution start command line is automatically moved to the next command line each time one command is sent, the supervisor changes to the command. If there is not, it suffices to omit the specification of the execution start command line and input the command transmission instruction as it is, so that the command selection instruction operation can be simplified.

The present invention is not limited to the above embodiment. For example, a pause code for recognizing a pause may be provided in the character string of the command. In this way, a pause time can be provided between commands or between command lines, which allows the command execution timing to be delayed by the required timing. In addition, the configuration of each device, the configuration of the system, the type of the monitored device to be applied, and the like can be variously modified and implemented without departing from the scope of the present invention.

[0071]

As described above in detail, according to the present invention, a storage means for storing a plurality of command information necessary for collecting monitoring information is provided in advance, and a command arbitrary selection mode is set according to a predetermined mode designating operation. And a command setting control means for controlling the command arbitrary transmission mode is set, and a plurality of command information stored in the storage means is selectively displayed to display the displayed command information. When a predetermined command designation operation is performed for, the corresponding command information is selectively sent to the monitored device, and the monitoring information returned from the monitored device in response to the sent command information is displayed. It is designed to be received.

Therefore, according to the present invention, it is possible to provide a monitoring device capable of collecting monitoring information accurately and swiftly by simplifying a command input operation when arbitrarily collecting monitoring information.
