Abstract

PROBLEM TO BE SOLVED: To greatly improve the maintainability of a system by making it possible to refer to control log data even a long time later without making internal processes and a flow of a series of processes of equipment control hard to see. SOLUTION: When control log data is generated as a result of equipment control, a CPU 2 stores the control log data in a control log file 30 of a memory 3 and updates the registration address. The CPU 2 stores the 1st half area of a control log file on an HD(hard disk) 7 when the updated registration address is the center address plus one and the 2nd half on the HD 7 when the head address. The CPU 2 once receiving a return indication for the control log data from a VDT 5 (video display terminal) returns the control log data stored on the HD 7 to the 1st half area of the control log file.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control log file management apparatus, and more particularly to a control log data management apparatus which edits and transmits commercials, and controls the contents of communication with external devices and the status of internal processing in a CM editing and transmission apparatus (video file apparatus). It relates to a method of managing a control log file stored as a file.

[0002]

2. Description of the Related Art A CM editing / sending device (video file device) records (filing) a CM material on a recording medium in the CM editing / sending device and records a CM material in the CM editing / sending device in which the CM material is recorded. Controlled equipment is controlled by control information contained in a plurality of control data for recording (unifying) a CM on a unified tape for CM transmission and directly transmitting (direct OA) a CM from a recording medium in a CM editing and transmitting apparatus. This is a device for controlling the editing and transmission of CMs at a broadcasting station by a broadcasting device.

Conventionally, in the CM editing and transmitting apparatus, information (information exchanged with the controlled device) and internal processing when controlling the controlled device such as a recording medium and a unified tape in accordance with the control data. Is stored in a control log file in a data storage device (memory) for storing the control data.

That is, as shown in FIG. 6, when control log data is generated by performing device control (step S31 in FIG. 6), the control log data is stored at a designated registration address in a control log file (FIG. 6). FIG. 6 step S3
2).

In this case, it is checked whether or not the address storing the control log data is the end (END) address of the control log file (step S33 in FIG. 6). If not, the registered address is incremented by 1 (move to the next address). (Step S34 in FIG. 6), and if it is an end address, the registration address is set to the beginning (TO
P) The address is changed (step S35 in FIG. 6), and registration of the control log data is terminated (step S36 in FIG. 6).

In this CM editing and transmitting device, when storing control log data such as information for controlling a controlled device, the control log data on a memory having a capacity of about 2000 and having a ring buffer structure is stored. They are stored in a file and output to a floppy disk or list when needed, and referenced.

[0007]

In the above-mentioned conventional CM editing and transmitting apparatus, the control log file has a ring buffer structure due to physical restrictions such as a limitation of a memory capacity.
It has a capacity of about 00 cases.

However, with such a capacity, only about two to three hours of past control log data remains in the case of frequent device control during the daytime or the like, and 4 to 5 hours due to the nature of the ring buffer structure of the control log data file. If the time is longer than the time, the past control log data is overwritten, so that it is impossible to refer to the old control log data after a certain period of time. Therefore, when a problem occurs, it is necessary to stop the device control before overwriting and output the control log data to a floppy disk or a list.

On the other hand, JP-A-5-2855 discloses an interface device provided between a control device and a controlled device.
By providing a logging function for storing error information and various operation state tracking history information in the interface device, the method of reducing the load on the control device and the load on the data storage device for storing the control log data has been proposed. It has been disclosed.

However, in this method, it is difficult to apply the method to a device in which the interface device cannot be arranged between the control device and the controlled device, or the interface device may not be used depending on the type of the controlled device to be used. It must be newly developed.

Although the control log file also stores information on internal processing other than device control, even if the interface device has a logging function, only information on device control can be stored. In addition, it becomes difficult to understand the flow of a series of processes for device control.

Accordingly, an object of the present invention is to solve the above-mentioned problems and to make it possible to refer to the control log data even after a long time without obfuscating the flow of a series of processes of internal processing and device control. An object of the present invention is to provide a control log file management device that can greatly improve the maintainability of the system.
