Abstract

When a trouble occurs in a machine tool (20) sold by a machine tool manufacturer to a customer, a failure analysis apparatus (11) installed in a service center (10) of the machine tool manufacturer remotely controls the machine tool (20) to obtain operation information or alarm information of the machine tool (20) and performs failure analysis based on such information. In the service center (10), a plurality of failure analysis apparatuses (11) comprising personal computers, and a server (12) which are connected to the failure analysis apparatuses (11) for communication and to which a global IP address for the exclusive use is allocated are installed. Machine tools (20) of customers are connectable to the server (12) via the Internet (30).

Claims

1. A remote control system comprising:

a plurality of object apparatuses to be controlled;

a plurality of controlling apparatuses for controlling the object apparatuses; and

a server for connecting the object apparatuses and the controlling apparatuses to each other for allowing communication therebetween;

wherein the server establishes a communication path between a particular one of the object apparatuses and a particular one of the controlling apparatuses only when both of the particular object apparatus and the particular controlling apparatus request communication.

2. The remote control system according to claim 1, wherein object apparatuses to be controlled and/or controlling apparatuses can be registered in the server in advance as apparatuses which are allowed to be connected.

3. The remote control system according to claim 1, wherein the object apparatuses comprise machine tools, and wherein the operating apparatuses comprise failure analysis apparatuses for analyzing failure of the machine tools while remotely controlling the machine tools.
