Remote system monitoring apparatus and method {AN APPARATUS AND A METHOD FOR MONITORING REMOTE SYSTEMS}

The present invention provides a device and method for remotely controlling a system by overcoming the limitations of distance and equipment when it is desired to control the system from a place other than a predetermined operation terminal in monitoring and managing a specific device. In particular, through a local management system in accordance with the specifications required by the remote system through the interface such as RS-232 (Recommendation Standard) or TCP (Transmission Control Protocol) / IP (Internet Protocol), without a separate interface specification The present invention relates to a network management apparatus and method for performing a state monitoring and control function for a managed system.

As is well known to those skilled in the art, RS-232 is originally an electrical standard for interconnecting data terminal equipment (DTE) and data line termination equipment (DCE) such as modems or data concentrators, and is recommended by the Electronics Industries Association (EIA). It is established as a Recommendation Standard (RS), and is used as a standard interface for mutual communication of control signals and data between a central processing unit and peripheral devices.

The prior art of the remote system monitoring apparatus and method was possible only through a predetermined operating terminal, there was a problem that only a predetermined form of communication through a data communication using a special protocol to perform in a number of different terminals.

Referring to FIG. 1, the management structure of a conventional system can be monitored and coordinated by an operator through a designated terminal, and a remote management system and a region can be used to remotely perform a failure and control function of the system. It was possible only by defining physical and logical protocol specifications between management systems to send and receive data. As a result, various functions such as retransmission and network inspection are required to secure communication reliability, and when the data specification is changed, the interface module must be changed.

Another prior art is the 'Remote control of gateway function in a wireless data communication network' disclosed in US Pat. No. 5,559,800. This method is to manage the network wirelessly. However, since this method is also a wireless method, it is inconvenient to pass through many additional communication equipment and gateways.

Therefore, in order to solve the above problems, the present invention provides an X-Window supported terminal or PC (Personal Computer) using Unix's Network File System (NFS) to easily monitor system failures even from a remote location. If you want to see the failure status of the system in the Windows environment, and if you want to see the various status, failure, and statistics messages that occur in the system from a remote location, you can also use the GUI (Graphic User Interface) to see the operator. If you want to perform the control function for the purpose of providing a variety of environments according to the type and environment of the system to be performed.

In other words, in case of Unix system, use rsh (Remote Shell), in case of RS-232 interface, provide remote login function and in case of PC GUI environment, use separate socket interface.
