In the prior art described above, when changing, maintaining, and managing various parameter data, an operator of a system management device goes to a site where the device is installed and operates the system management device. This means that not only is it expensive to go out, but also in the event of a failure or trouble with the video switch system, a considerable amount of time is needed to go out, especially for long distances. In some cases, the operation of the user is hindered, and there is a considerable problem in terms of economy, reliability and efficiency.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the problem of the prior art, that is, waste of expenses and poor response when a failure or trouble occurs, and to efficiently perform change, maintenance, and management of various parameter data. An object of the present invention is to provide a remote management system for a video switch system.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a first connection means for connecting a LAN line of a system management system of a video switch system to a public communication line, an installation place of a video switch control device and an installation of a remote management device. This is achieved by configuring a remote management system with a public communication line connecting a place, a second connection unit that connects the public communication line and the remote management device, and a remote management device that performs system management.

[0008]

According to the above configuration, since the remote management device is connected to the video switch system via the public communication line, if the remote management device is installed at a certain location, the video management system can be freely accessed from there. It is possible to change, maintain and manage various parameter data, and centrally control uploading and downloading without an operator of the system management apparatus going to the installation site.

Step 8 is an offline command processing task for confirming whether parameter data processing can be performed offline, step 9 is a data printout processing task for printing parameter data offline, and step 10 is a parameter printing task offline. A data upload processing task for performing data upload processing, and a step 11 is a data download processing task for performing offline parameter data download processing.

Next, the processing operation of the remote management system according to the present embodiment will be described with reference to the drawings. 7 and 8 are diagrams showing a processing sequence between the remote management device and the video switch system. FIG. 7 shows a case where parameter data is changed, maintained and managed online, and FIG. This shows a case where data upload processing and download processing are performed, respectively.

In FIG. 7, first, a line number owned by a video switch system at a site is dialed from a remote management device to connect to a public communication line, and a line with the video switch system is set to a connected state. I do. The processing sequence at the start of operation is as follows.
An on-line remote control-in request is transmitted to the main control unit via the H.232C line, the public communication line, and the LAN communication line. Upon receiving this request, the main control unit sends a standby command to the system management device. Upon receiving this command, the system management device sends a standby command response to the main control unit. Upon receiving this response, the main control unit transmits a remote control-in response to the remote management device via the LAN communication line, the public communication line, and the RS-232C line. As a result, the remote management device and the video switch system are connected, and the remote control can be operated. After that, the parameter data is changed, maintained, and managed online.

In the processing sequence at the end of the operation, first, a remote control out request is transmitted from the remote management device to the main control unit via the RS-232C line, the public communication line, and the LAN communication line. The main control unit is
When this request is received, a standby release command is transmitted to the system management device. Upon receiving this command, the system management device transmits a standby release command response to the main control unit. Upon receiving this response, the main control unit transmits a remote control-out response to the remote management device via the LAN communication line, the public communication line, and the RS-232C line. Thereafter, the remote management device disconnects the connection to the public communication line, and the process ends.

In FIG. 8 as well, the remote management device and the video switch system are connected via a public communication line and become operable, and the processing sequence at the start of operation is performed in conjunction with FIG. This is the same as the description given above. Next, after confirming that the video switch system is not performing user work, the main control unit of various parameter data, uploading from the workstation to the remote management device, and the main control unit from the remote management device are performed offline. Perform a download to the workstation.
The processing sequence at this time is as follows: the system management device replaces the remote management device, and a gateway, a public communication line,
Network control unit, modem, RS
Except that a −232 line is interposed, the processing sequence is essentially the same as the processing sequence performed in FIG. The processing sequence at the end of the operation is the same as that described for FIG.

[0016]

According to the present invention, by connecting a remote management device to a video switch system via a public communication line, an operator of the system management device does not need to go to the site where the video switch system is installed. Each video switch system can be freely accessed from a remote management device installed at a certain location, and various parameters can be changed, maintained and managed, and upload and download can be centrally controlled. As a result, it is possible to reduce costs and to quickly respond to the occurrence of a trouble or a trouble, which has a remarkable effect on improvement of economy, reliability and work efficiency.
