2. Description of the Related Art As shown in FIG. 5, a conventional television studio master system includes an automatic program control device 11, a main line control device 12, and a main line switcher 13 as main parts, and a maintenance device 14 and a printer 15. Have The automatic program control device 11 outputs the control data of the main line switcher 13 in synchronization with the second pulse according to the program transmission program registered in advance, and the main line control device 12 outputs the control data output from the automatic program control device 11. The main line switcher is controlled in synchronism with the V trigger, which is the unit of time for switching the video screen, and the program is switched. The main line control device 12 is provided between the automatic program control device 11 and the main line switcher 13 because the responsiveness until the main line switcher 13 is switched differs depending on the single unit. This is because the timing is adjusted by the V trigger so as not to exist.

Further, in order to help recovery in the event of a failure in the control system such as the automatic program control device 11 or the main line control device 12, the automatic program control device 11 causes the main line control device 12 to specify the contents of the control data. When a hardware error occurs in the CPU in the automatic program control device 11 at the time of output, it has a function of saving history such as an error code indicating the error in the internal memory as log data, and also the main line control device 12 Also, the contents of the control data received from the automatic program control device 11, the reception time thereof, the error information of the control data, the contents of the data output to the main line switcher 13, the output time thereof, and the hardware in the CPU in the main line control device 12. When a hardware error occurs, the history such as the error code indicating the error is stored in the internal memory as log data. And it has a function resides. And
The log data stored in this way can be edited and output from the printer 15 for the log data of the automatic program control device 11, and can be edited and output from the maintenance device 14 for the log data of the main line control device 12. ing.

Further, normally, the configuration shown in FIG. 5 is duplicated in the active system and the standby system. When a failure occurs in the active system, the operator operates the system change switch to switch the active system to the active system. By manually switching between the backup system and the standby system, automatic program transmission can be continued. The system switching may be automatically performed without operating the system change switch.

Since the conventional TV studio master system has the above-mentioned structure, when an error occurs in the control system, the operator operates the system change switch to take an emergency measure to switch between the active system and the standby system. By taking it, the operation of automatic program transmission can be continued. Further, log data held in the memories of the automatic program control device 11 and the main line control device 12 is output to the printer 15 and the maintenance device 14 to obtain log data useful for investigating the cause of failure. be able to. However, a certain degree of specialized knowledge is required for the output of log data from each of the devices 11 and 12, analysis of the log data, identification of a failure location, and the operation of this treatment,
The actual situation is that the person in charge on the maker side, who receives the contact from the user, actually carries out the operation.

[0006]

As described above, in the conventional TV studio master system, the log data useful for investigating the cause of the failure is collected by the automatic program controller and the main line controller. The output of the log data, analysis, identification of the cause, and the work of this action are all performed by the manufacturer who has been contacted by the user, so even if the failure is a simple one, the manufacturer responds each time the failure occurs. Therefore, there is a problem that it takes a considerable amount of time for this treatment.

Therefore, an object of the present invention is to automatically perform processing such as log data collection, failure location identification, and treatment method presentation when the system is switched to the standby system due to a failure occurring in the active system. The goal is to provide a TV studio master system that can be run in a dynamic manner.

Although the technical field is different from that of the television studio master system, Japanese Patent Laid-Open No. 64-72299 discloses that a failure signal from each part of the plant is constantly monitored and is uniquely determined from the failure signal when a failure occurs. There is disclosed a technique of displaying a failure message indicating a failure location that is generated and collecting and displaying a history of process data related to the failure location. If this technology is applied to the TV studio master system of the present invention, it becomes possible to collect and display log data when the active system fails, but since there is no log data analysis function, it is necessary to analyze the log data first. Prompt treatment is difficult because the identified failure location cannot be presented and the treatment method has no presentation function.
Further, there is a problem that the load of the active system increases because the log data is collected even in the case of a minor failure that does not result in a system change. In contrast, in the present invention,
Since it has a log data analysis function and a treatment method presentation function, it is possible to analyze the log data to find out the location of the failure that can be identified for the first time and to take swift action. In addition, log data collection is triggered by a system change. It does not unnecessarily increase the load on the active system to start etc.

[0009]

In order to achieve the above object, the present invention provides an automatic switch for outputting main line switcher and control data of the main line switcher in synchronization with a second pulse according to a program sending program registered in advance. A program control device and a main line control device for controlling the main line switcher in synchronization with a V trigger which is a unit of time for switching a video screen according to control data output from the automatic program control device In a television studio master system that is duplicated with the above, log data collection means for starting operation upon system switching and collecting log data from the automatic program control device and main line control device of the newly standby system And a log data analysis unit that analyzes the log data collected by the log data collection unit to identify a failure location, and the log The treatment methods for fault location identified in over data analyzing means includes a maintenance device having a treatment advice presentation means for presenting to the operator.

Further, the log data analysis means includes a history of the control data sent to the main line control device included in the log data collected from the automatic program control device and the automatic program control device included in the log data collected from the main line control device. The control data history received from the device is compared with each other, and if they do not match, the communication interface between the automatic program control device and the main line control device is determined to be the faulty part.

In the television studio master system of the present invention, in the television studio master system in which the active system and the standby system are duplicated, since a failure occurs in the active system, the active system and the standby system are operated by operating the system change switch, for example. When the system is switched, the maintenance device starts the operation upon the switching of the system, and first, the log data collecting means causes the system to newly become the standby system,
That is, log data is collected from the original active program control device and main line control device in which the failure has occurred, and then the log data analysis means analyzes the collected log data to identify the failure location. Then, the treatment advice presenting means presents the operator with a treatment method for the fault location identified by the log data analyzing means.

5A, 45B, first flags 46A, 46B, second flags 47A, 47B, advice information file 48A,
48B, CRT 49A, 49B, printer 50A, 50
B is included.

In FIG. 1, 5 is a system change switch, and the output of this switch is supplied to the automatic program control device 1A, main line control device 2A, main line switcher 3A and maintenance device 4A of the system A. , Automatic program control device 1B of system B, main line control device 2
B, main line switcher 3B and maintenance device 4B
Is also supplied.

In the television studio master system of this embodiment, either system A or system B operates as the active system, and the remaining system operates as the standby system. For convenience of explanation, assuming that the system A is the active system and the system B is the standby system, the automatic program control device 1A, the main line control device 2A, and the main line switcher 3A of the active system A automatically control the transmission of programs. That is, the CPU 11A of the automatic program control device 1A outputs the control data of the main line switcher 3A in synchronization with the second pulse according to the program transmission program registered in advance,
The CPU 21A of the main line control device 2A controls the main line switcher 3A in synchronism with the V trigger, which is a unit of time for switching the video screen, according to the control data output from the automatic program control device 1A, and switches the program. And
During such a control operation, the CPU 11A uses the history such as the content of the control data, the time when it is output to the main line control device 2A, and the error code indicating the hardware error when the hardware error occurs in the memory 12A as log data.
The CPU 21A stores the contents of the control data received from the automatic program control device 1A, the reception time thereof, the error information of the control data, the contents of the data output to the main line switcher 3A, the output time thereof, When a hardware error occurs in itself, a history such as an error code indicating the error is stored as log data in the memory 22A.

Now, with the system A operating as the active system as described above, the automatic program control apparatus 1A of the system A
The main system control device 2A, or the communication interface connecting the two has failed, and the automatic system A does not correctly operate to automatically transmit the program. Therefore, the operator operates the system change switch 5 to operate the system A switch. When the system is switched to the standby system and the system B is switched to the active system, the system B, in place of the system A, continues the automatic program transmission operation. That is, the CPU 11B of the automatic program control device 1B outputs the control data of the main line switcher 3B in synchronization with the second pulse in accordance with a program transmission program registered in advance, and the C of the main line control device 2B outputs the control data.
The PU 21B controls the main line switcher 3B in synchronism with the V trigger, which is the unit of time for switching the video screen, according to the control data output from the automatic program control device 1B, and switches the program.

Then, triggered by the above-mentioned switching of the system,
The maintenance devices 4A and 4B of the system A and the system B start operating.

Operation of Maintenance Device 4A of System A In the maintenance device 4A, the log data collecting means 41A first starts its operation and executes the processing shown in FIG. First, it is determined whether or not the own system A has switched from the active system to the standby system (S1). In this case, since the system A has been switched from the active system to the standby system, the determination result of step S1 is YES.
Therefore, the maintenance device 4A executes the following series of operations.

The log data collecting means 41A issues a log request (log data request command) requesting the log data transmitting means 13A of the automatic program control device 1A to transmit the log data (S2), and also the main line. Control device 2A
A log request (log data request command) requesting the log data transmission means 23A to transmit the log data is also issued (S3). Then, the log data collecting means 41
A waits for log data to be transmitted from the request destination.

When the log data transmitting means 13A of the automatic program control device 1A receives a log request from the log data collecting means 41A, it transmits a telegram containing the log data stored in the memory 12A to the log data collecting means 41A. Similarly, when the log data transmission means 23A of the main line control device 2A receives the log request, it also transmits a telegram containing the log data stored in the memory 22A to the log data collection means 41A.

When the log data collection means 41A receives a message from the automatic program control device 1A or the main line control device 2A (S4), it determines which device the log data is from (S5). Then, in the case of a message including log data from the automatic program control device 1A, the received log data is
Is saved in the log area 44A (S6), and the first flag 46A is turned ON. On the other hand, when the electronic message including the log data is received from the main line control device 2A, the received log data is saved in the second log area 45A (S8), and the second flag 47A is turned ON. And the first and second
When both flags 46A and 47A are turned on,
That is, when the collection of the log data of the automatic program control device 1A and the log data of the main line control device 2A is completed (YES in S10), the log data analysis means 42A is activated (S1).
1).

When the log data analysis means 42A is activated, it starts the processing shown in FIG. First, an error code indicating a hardware error is searched for in the first and second log areas 44A and 45A (S20). Then, when the error code of the hardware error is found (S
21 is YES), and the treatment advice presenting means 43A
To the second log area 4 (S22).
The log data in 4A and 45A is output to the treatment advice presenting means 43A (S29), and the first and second flags 4 are output.
6A and 47A are turned off (S30), and the process ends.

On the other hand, when there is no error code of the hardware error, that is, the failure this time is the CPU 11A of the automatic program control device 1A or the CP of the main line control device 2A.
If the error of U21A is not the cause, it is checked whether or not a failure has occurred in the communication interface connecting the automatic program control device 1A and the main line control device 2A (S23).
To S28). This is because the control data sent from the first log area 44A holding the log data of the automatic program control device 1A to the main line control device 2A is searched one by one in the order of the sending time (S23, S26, S27), and the same control data is obtained. Is the second
This is performed by checking whether or not the log area 45A exists (S24). When the control data existing in the first log area 44A does not exist in the second log area 45A (S
No in No. 25), it means that the control data sent from the automatic program control device 1A has not been received by the main line control device 2A, and it is considered that a failure has occurred in the communication interface between both devices. The error code corresponding to the failure is notified to the treatment advice presenting means 43A (S2).
8). Then, the first and second log areas 44A and 45
The log data in A is output to the treatment advice presenting means 43A (S29), and the first and second flags 46A and 47A are output.
Is turned off (S30), and the process ends. If both control data match (Y in S27).
ES), it means that the failure location could not be identified, and the processing is terminated through steps S29 and S30.

Now, in the advice information file 48A, advice information in which a treatment method for a faulty part is described corresponding to each error code is registered in advance. When the error code is notified from the log data analysis means 42A, the treatment advice presenting means 43A searches the advice information file 48A for advice information corresponding to the notified error code, as shown in FIG. 4 (S31). Then, the retrieved advice information is displayed on the CRT.
It is presented to the operator by displaying it on the screen of 49A (S32). Instead of the display on the screen, the advice information may be printed from the printer 50A together with the screen display. In addition, the treatment advice presenting means 43A
Outputs the log data output from the log data analysis means 42A to the CRT 49A and / or the printer 50A.

By the operation of the maintenance device 4A as described above, operations such as collection of log data of the system A in which a failure has occurred, analysis of the log data, identification of a failure point, and presentation of a treatment method are performed immediately after the system change. Be seen. Here, in the advice information, in the case of a simple failure, the recovery method is clearly specified, so that the recovery work by the operator himself is possible. In the advice information, the operator is instructed to contact the manufacturer in the case of a failure that is difficult to recover by work by the operator.

Operation of Maintenance Device 4B of System B In the maintenance device 4B as well, the log data collecting means 41A first starts the operation and executes the processing shown in FIG.
Since the own system B has switched from the standby system to the active system, the determination result of step S1 is NO, and the maintenance device 4 concerned
B ends the process at that point. That is, in this embodiment,
Only the maintenance device in the system switched from the active system to the standby system operates substantially.

In the above, the case where the system is switched by the operation of the system change switch 5 has been described. However, in the case where the TV studio master system itself automatically switches the system when a failure occurs in the active system. Is also applicable. In this case, each of the maintenance devices 4A and 4B is configured to periodically monitor the working / standby state of its own system and start the operation when the change is detected.

[0028]

As described above, according to the television studio master system of the present invention, the following effects can be obtained.

In the case of a simple failure, log data is collected from the automatic program control device and the main line control device, a failure point is identified by analyzing the collected log data, and a treatment method for the failure point is automatically presented. In this case, the user can carry out the work of this treatment by himself, and it becomes possible to carry out the quick treatment as compared with the current situation in which the maker side copes with each occurrence of a failure.

Since a series of processes such as collection of log data by the maintenance device, analysis of log data, and presentation of a treatment method are started at the time of switching between the active system and the standby system, the load on the active system is neglected. It is possible to prevent the increase, and it is not necessary for the operator to separately give any instruction for collecting the log data. Therefore, it is possible to quickly start the processing such as collecting and analyzing the log data without trouble.

Unlike the failure inside the automatic program control apparatus and the main line control apparatus, the failure of the communication interface connecting the two has been easily overlooked in the past, but in the present invention, it is included in the log data collected from the automatic program control apparatus. Since the log data analysis means has a function of comparing the history of control data sent to the main line control device and the history of control data received from the automatic program control device included in the log data collected from the main line control device, It is possible to detect the loss of communication information due to the failure of the communication interface, and it is possible to automatically identify the failure of the communication interface between the automatic program control device and the main line control device.
