no. 1 approach

[0028] Hereinafter, a first embodiment according to the present invention will be described with reference to the drawings. In addition, in the following first embodiment, the same symbols are attached to the same components.

[0029] figure 1 It is a block diagram showing the configuration of a remote maintenance system according to the first embodiment of the present invention. In the remote maintenance system, a local area network system having a digital multi-function device 20 (hereinafter referred to as a facsimile device with copying, printing and scanning functions) A local area network (called LAN) and the digital composite device 20 are connected to the center device 40 through the Internet 90 .

[0030] The LAN system according to the first embodiment includes N client personal computers 30-1 to 30-N (hereinafter referred to as 30 collectively), a digital composite device 20 connected to a public telephone network 80 via a public telephone line L, and The router 6...

no. 2 approach

[0058] Next, a second embodiment according to the present invention will be described with reference to the drawings. In addition, in the following second embodiment, the same symbols are attached to the same components.

[0059] Figure 8 It is a block diagram showing the configuration of a remote maintenance system according to a second embodiment of the present invention. In the remote maintenance system, a local area network system including a digital multi-function device 2020 (hereinafter referred to as a facsimile device with copying, printing and scanning functions) is provided. The local area network (LAN) and the digital multi-function device 2020 are connected to the center device 2040 through the Internet 2090 which is an IP (Internet Protocol) network.

[0060] The LAN system related to this embodiment includes N sets of client personal computers 2030-1 to 2030-N (hereinafter referred to as 2030 collectively), a digital multi-function device 2020 connected to a p...

no. 3 approach

[0083] Fig. 14 shows that instead of the center of Fig. 13 being called, by Figure 10 A flow chart of the center call process according to the third embodiment, which is another example other than the second embodiment, executed by the main control unit 2101 of the center device 2040 of .

[0084] In step S2021 of FIG. 14, it is first judged whether a center call signal has been received from the digital composite device 2020, and the process of step S2021 is repeated until it is "Yes". The customer information management table 2108b is searched for by calling the equipment information contained in the signal, and the corresponding customer management information is displayed on the display unit 2104 to report. Next, in step S2023, a call control paging signal is sent according to the retrieved corresponding customer management information, and a voice communication session is established with the corresponding digital multi-function device 2020 using, for example, SIP proced...

Abstract

Here is remote protection system that can automatically inform error code of communication terminal to center unit, and then the center unit will automatically call the user whose device is broken down. Furthermore, there is a center unit that can simply communicate with operators according to user directions when the communication terminal device is broken down. The remote protection system comprises of a communication terminal device and a center unit. The center unit is linked to the communication terminal device by means of settled communication line and manages errors of the communication terminal device. Furthermore, the center unit comprises a memory unit that stores facility information of the communication terminal device and uses' information tables. By responding to the error-informing signal of the communication terminal device and according to the uses' information tables, the center unit can automatically send out call sign by means of the communication line, then the communication terminal device answers the call sign and reports to the user.

Description

technical field [0001] The present invention relates to a remote maintenance system including, for example, a communication terminal device such as a digital composite device or a facsimile device, and a center device for remotely managing failures thereof, the communication terminal device and the center device. Background technique [0002] In the past, the following remote maintenance system has been put into practical use, that is, the remote maintenance system remotely monitors the working conditions of various electronic instruments or devices installed in homes, offices, factories, etc., and when an abnormality occurs, etc. In this case, perform maintenance on the target device. In such a remote maintenance system, specifically, remote diagnosis through a telephone line, remote control of the process of reading data stored in a terminal device from a service center, or writing data to a terminal device are performed. processing. [0003] In the public telephone netw...
