Abstract

A centralized control system comprising interface circuits which are provided in respective terminal devices requiring field service such as copying machines or automatic vending machines and collect functional information concerning functions of the terminal devices and abnormality information showing their abnormality; communication units which are provided at every one or plural interfaces circuits and transmit collected information as the need arises; and remote control device which receives transmitted information and selectively displays it on a display unit to execute a plurality of control processing at every terminal device. Abnormality information is announced whenever it occurs or at a predetermined time according to a degree of abnormality, and information concerning the abnormality information announced is displayed on a part or full of the whole display picture screen concerning all the control processing. Further, a record of the abnormality information is stored and displayed and also information on a function along with usage quantity information of consumable goods are displayed in lists, thus notice of abnormality when it occurs and search for its cause are accurately conducted. Still further the system accurately predicts a date for replacement or supply of the consumable goods on the basis of usage quantity information, thus reducing using-up of the consumable goods.

Claims

1. A centralized control system for a plurality of terminal devices comprising:

information collection means provided in each of said terminal devices for collecting information of device status including at least one of functional information concerning the function of each terminal device and information showing abnormality of each terminal device and its contents;

terminal communication means connected to each information collecting means for monitoring collected functional and abnormality information and transmitting it as the need arises; and

remote control means for receiving said information from said each terminal communication means, selectively displaying the received information on a display unit and performing control processing at each terminal device,

said remote control means including display control means for displaying information relative to said abnormality information of a terminal device on a part or all of a plurality of display screens of said display unit which displays the control processing immediately when said abnormality information is received irrespective of the type of control processing being carried out for the terminal device for which the abnormality is displayed.

2. A centralized control system for terminal devices as set forth in claim 1, wherein a said terminal communication means previously determines an order of priority of transmittances according to contents of the abnormality of said abnormality information and said abnormality information to said remote control means in the determined order of priority.

3. A centralized control system for terminal devices as set forth in claim 2, wherein, when said abnormality information having the highest order of priority is collected by said information collecting means, said terminal communication means transmits the collected abnormality information to said remote control means whenever said abnormality information is collected.

4. A centralized control system for terminal devices as set forth in claim 2, wherein said terminal communication means determines a plurality of transmittance time zones according to the determined order of priority, and transmits said abnormality information in a determined time zone.

5. A centralized control system for terminal devices as set forth in claim 1, wherein said information collecting means collects a plurality of informations from an automatic vending machine as a terminal device.

6. A centralized control system for a plurality of terminal devices comprising:

information collecting means provided in each of said terminal devices for collecting information on device status including at least one of functional information concerning the function of each terminal device and information showing abnormality of each terminal device and its contents;
