Equipment management system

An equipment management system, comprising:

• terminal devices attached to managed pieces of equipment for transmitting equipment management data with which those pieces of equipment are managed;
• a first host computer linked with one group of terminal devices through a communications network for collectively managing that one group of terminal devices in terms of specific items of management data;
• and
• a second host computer linked with another group of terminal devices including at least part of said one group of terminal devices for collectively managing that other group of terminal devices in terms of other items than said specific items of management data,
• wherein the terminal devices, the first host computer, and the second host computer are linked through a network;
• wherein the first host computer sets initial data including a symbol for identifying the managed piece of equipment on each terminal device;
• wherein, out of said initial data, a necessary data including said symbol is registered in the second host computer, so that the second host computer can cope with any of the terminal devices;
• and
• wherein said second host computer comprises:
• a managed equipment list display means which, on receiving transmission from a terminal device while an item concerning a piece of equipment corresponding to that terminal device has not been processed in the second host computer, displays said symbol transmitted from the terminal device on a managed equipment list together with an indication indicating lack of the item, and which, when said item has been processed, changes the indication indicating lack of the item to an indication indicating completion of processing of the item;
• and
• an instruction signal generating means which instructs the terminal device of the piece of equipment appearing on the list displayed on the managed equipment list display means to keep transmitting periodically until the item concerning the piece of equipment is processed, by transmitting an instruction signal to that terminal device during data reception from the terminal device.
