Description

Description: TECHNICAL FIELD The present invention relates to a remote diagnostic communication method in a device that receives remote diagnostic data from a remote terminal.

2. Description of the Related Art Among devices that receive remote diagnostic data from a remote terminal, a conventionally proposed device negotiates a unique procedure during a facsimile procedure between predetermined facsimile apparatuses, and requests a remote diagnostic data. Data was being received. That is, after a call is made to the remote terminal, the call is exchanged using standard facsimile procedures,
In that procedure, a request for remote diagnostic data was made by switching to an original procedure.

[Problem to be Solved by the Invention] However, the above-described conventional example has the following disadvantages.

(1) Since it takes time from the connection to the remote terminal to the start of the exchange of the request for the remote diagnostic data, the occupation time of the communication line becomes longer, and the communication cost increases.

(2) In order to request remote diagnostic data or the like by a unique procedure, the function of the above-described unique procedure must be added to the remote terminal.

Means for Solving the Problems In view of the above-described problems, the present invention provides a remote diagnostic communication method in a device that receives remote diagnostic data from a remote terminal and displays or prints information according to the remote diagnostic data. Setting data indicating a request for remote diagnosis in an information area provided for terminal designation in the digital public line network; and transmitting the terminal designation information set in the step in accordance with the procedure of the digital public line network. And a remote diagnostic communication method comprising the steps of:

Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

<Description of Configuration (FIGS. 1 and 2)> FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is an external perspective view showing the configuration of the entire apparatus in this embodiment. FIG.

In the figure, reference numeral 10 denotes a reader which reads a predetermined document and outputs an electric signal. Reference numeral 20 denotes a communication device main body, which includes a reader / printer interface 21, an image compression unit (ICU) 22, a program memory (PMEM) 23, and a bit move unit (BMU) 24.
And image memory (IMEM) 25 and video RAM (VRAM) 2
6, a central processing unit (CPU) 27, a bus 29, and a communication unit (CCU) 30.

The ICU 22 compresses or decompresses data, and employs two-dimensional compression (high compression) in order to increase the coding rate. The PMEM 23 is an operation system program / controller for controlling input / output devices provided around the communication device main body 20 and each unit in the communication device main body 20.
The remote terminal has a memory area for loading an application program, a memory area for a fault information table of a remote terminal which extracts a sub address used as an index, and a font memory area for converting character codes into images.

Also, PMEM23 is a memory management unit (MM
EM) and documents stored on the hard disk 50
The buffer is used to transmit the received document via the CCU 30, store the received document on the hard disk 50, set the sub-address for the remote diagnosis request used in this embodiment, and retrieve the sub-address of the other party sent. It also has a work area.

Further, a memory area for storing the line address of the partner terminal by the keyboard 61 is also included.

The BMU 24 edits an image on the CRT 60, and enlarges, reduces, rotates, moves, or cuts a predetermined image. The IMEM 25 has a memory space of 4 Mbytes, and stores an image from the reader 10, stores an edited image by the BMU 24, and stores data expanded by the ICU 22.

The CCU 30 connects to the network through the ISDN line 40, makes an inquiry about a failure situation using a subaddress described later, receives the diagnosis result as user information, and displays or outputs information on the failure situation to the CRT 60 or the printer 70. I do.

Further, a hard disk device 50 and a floppy disk device 51 are provided as external storage devices. CRT60
Is an apparatus for displaying a failure status of a partner terminal and editing / displaying a document such as image data and character data used in the present embodiment. The keyboard 61 is used for inputting characters and the like and for inputting a sub address used in the present embodiment.

The printer 70 outputs information related to the partner terminal converted from the notified sub-address, or outputs a document.

<Description of Operation (FIG. 3)> Next, the operation of the remote consultation in the present embodiment will be described below with reference to the flowchart shown in FIG.

When a request for remote diagnosis is made by the operator (step S1), the value determined for the request for remote diagnosis is set in the subaddress (step S2), and the subaddress is specified together with the address of the specified communication device. And make a call (step S3). This call is made by the CCU 30 according to the ISDN communication procedure, and upon receiving a response from the other party (step S4), retrieves the user information from the other party device which is added to the response and sent (step S4). S5).

This user information is, as shown in FIG.
1, consisting of domestic subscriber number 42, sub-address 43, etc. In the present embodiment, the contents of the sub-address 43 are further added to the sub-address data identifier 44, the sub-address data length 45, the sub-address data 46, the remote diagnosis identifier 4
7. Remote diagnostic data length 48 and remote diagnostic data 49 are used separately.

Here, it is determined whether or not the extracted user information is a prescribed format (step S6). If the retrieved user information is a prescribed format, it is determined based on the contents of the above-mentioned user information (remote diagnostic data 49). Then, the information table shown in FIG. 5 is searched (step S7). As a result, if data matching the information table is searched (step
S8), and display or output the data to the CRT 60 or the printer 70 (step S9).

This processing is performed, for example, by using the remote diagnostic data shown in FIG.
When 49 matches one of the remote diagnosis data 1 to n (51) shown in FIG. 5, the remote diagnosis information 1 to n corresponding to the matched data 2
This is the process of outputting the remote diagnostic information 2 of (52).

Also, in step S5, when the user information is not returned from the partner terminal, or when the returned user information is other than the prescribed format (step S6), or when data is not retrieved from the information table in step S7. Indicates that the terminal is not subject to remote diagnosis
Display or output to T60 or printer 70 (Step Sl
0).

As described above, according to the present embodiment, a remote diagnosis request is added to a subaddress, a call is made, and predetermined remote diagnosis information is searched based on user information included in a response to the call. By doing so, remote diagnosis can be performed without unnecessary charge.

[Effects of the Invention] As described above, according to the present invention, the time until the start of exchange of a request for remote diagnostic data or the like can be reduced,
The occupation time of the communication line can be reduced, the communication cost can be reduced, and it is not necessary to provide a unique procedure as in the related art.
