The present invention relates to a remote diagnostic control method of a facsimile, and more particularly, to a method for diagnosing and controlling the status of a remote facsimile by communicating with a facsimile at a remote location by performing a remote diagnostic control protocol between a center facsimile and a remote facsimile.

In general, the facsimile is a service cost increase and the time required for the service is very high, because if the customer has any questions or problems in the system, A / S personnel should visit the place where the facsimile is located and diagnose and manipulate the condition of the facsimile. There was a problem. As a result, the facsimile machine requires a remote diagnostic control (RDC) function to reduce service costs and expedite services by adding remote diagnosis and simple repair functions through communication lines. The remote diagnosis control function receives a diagnostic command instead of receiving a document from the sender, sets the internal value accordingly, and sends the internally set value accordingly. A series of special commands are required to execute these commands, which use the Non Standard Format (NSF), which is not defined by the CCITT.

However, in the related art, only a facsimile machine having a function of remote diagnosis control using the NSF can be applied, and a remote diagnosis control cannot be performed in a facsimile without a remote diagnosis control function.

Accordingly, an object of the present invention is to provide a remote diagnostic control method for performing a remote diagnostic control service of all faxes regardless of a type in a center fax machine.

In order to achieve the above object, the present invention provides a method for remotely controlling a remote facsimile in a center facsimile, selecting a remote diagnostic control mode in the center facsimile and dialing the remote facsimile, and using the remote facsimile in the center facsimile. Performing a remote diagnosis control protocol between the center facsimile and the remote facsimile when dialing, analyzing a DIS during the procedure of the remote diagnosis control protocol, and searching for a match between the control code of the center facsimile and the remote facsimile; If the match is true, the remote fax sends all the option information and the option key input request command to the center facsimile, receives the option information sent from the remote facsimile, displays it on the LCD, and receives the option key input request command. Option value It is characterized in that it comprises a process of sending to the remote facsimile by inputting, receiving the option value received from the center facsimile and updating the corresponding option value to set the option value.

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

The preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3 above.

To perform remote diagnosis control function, MONITOR ALGORITHM and protocol are required.

Firstly, the monitor is an auxiliary device for controlling the main system by connecting it to any particular main system. Therefore, the main function of the monitor is to transmit data, receive data, display data, and print data. In this way, the monitor for performing the remote diagnosis control function performs the above four functions, and the functions other than the above four functions will be defined as non-standard so that they can be used for the user's purpose. The data format for the above-mentioned remote diagnosis controller certificate (RDC) is shown in Table 1 below.

In order to transmit the remote diagnostic control data such as the above format to the monitor facsimile or to receive it from the monitor facsimile, it is used in combination with a specific protocol used for the facsimile. Same as

If you receive 01 from the main facsimile, it will recognize as YES and proceed to the next step.

Therefore, the monitor facsimile mainly displays the data sent from the main facsimile on the LCD, prints through the printing unit, and responds to the data from the main facsimile. The actual operation is performed in the main facsimile.

Secondly, in order to realize the remote diagnostic control function of the monitoring method, it is necessary to add an additional function to the existing protocol, which is specified in the NSF as described above. That is, when the NSF recognizes the moni type remote diagnosis control function code, the remote diagnosis control protocol is executed.

The basic protocol of the facsimile is shown in Figure 4.

A general protocol transmission and reception procedure is performed as shown in FIG. 4. In general, the facsimile of the transmitting side recognizes the facsimile performance of the receiving side through the DIS and informs the receiving side of the transmission method in consideration of its performance.

The sender sends the test signal to the receiver in order to test whether the transmission method is possible and sends a document when the sender knows that the signal is received. After sending the document, it informs the sender of the situation, that is, whether there is a document to be sent, takes appropriate measures according to the response of the receiver, sends a line termination signal, and transfers the line.

In addition, the protocol for remote diagnosis control is shown in FIG.

In order to perform the remote diagnostic control function (RDC), the user first dials the facsimile of the facsimile to control, receives a signal indicating the normal fax performance, and then sends a signal through the NSS to the remote side. As with normal document reception, the receiving side fax enters the remote diagnosis control mode when information for the remote diagnosis control function is loaded in the number NSS which analyzed the signal of the transmitting side. In the remote diagnostic control mode, the LCD displays, prints content, and waits for keystrokes on the control station's facsimile. The operator at the control station appropriately controls the control according to the content of the printed and output message. The signal according to the key operation is sent to the user side again through the NSS, and the user repeats the above-described operation according to the program procedure. The termination of the function is terminated by the key operation of the control station by the program procedure of the user.

Referring to FIG. 2 and FIG. 3 to remotely control the user facsimile from the center facsimile according to the above protocol, the central processing unit 10 of the center facsimile is remote from the OPE 20 in step 201. If the diagnostic mode selection key is input and the remote diagnosis mode selection key is input, the process proceeds to step 202. In step 202, the central processing unit 10 displays the telephone number input request message of the remote facsimile on the display device of the OPE 20. At this time, the center fax user enters the remote phone number. In step 203, the central processing unit 10 checks whether the remote fax machine has completed the telephone number input, and if the remote fax machine has completed the telephone number input, dials the entered telephone number. In step 204, the central processing unit 10 transmits the CNG tones to the remote nuclear nuclear. Then, the remote facsimile receives it. In step 301, the central processing unit 10 of the remote facsimile checks whether the ring signal is received and sends the CED tone and DIS to the center facsimile in step 302 and step 303 when the ring signal is received. At this time, the central processing unit 10 of the center facsimile checks whether the CED tone signal is received in step 205, and proceeds to step 206 when the CED signal is received. In step 206, the central processing unit 10 checks whether the DIS is received. If the DIS is not received, the CPU 10 checks whether the set time has elapsed in step 207. If the set time has elapsed, the program is terminated. If the set time has not elapsed, the program continues to wait for DIS reception. If the DIS is received in step 206, the process proceeds to step 208. If the control code included in the DIS matches, the CPU 10 proceeds to step 209. In step 209, the central processing unit 10 transmits the DCS including the control code of the center facsimile to the remote facsimile. The central processing unit 10 of the remote facsimile checks whether the DCS is received in step 304, and if the DCS is not received, proceeds to step 305 to check whether the DCS is received for a predetermined time. If the DCS is received in step 304, the process proceeds to step 306 to check whether a control code exists. If the control code does not exist, the process proceeds to step 307 to receive a document. However, if the control code exists in the DCS in step 306 proceeds to step 308 transmits the option information that the remote facsimile to the remote facsimile and proceeds to step 309. In step 309, the option input display command (LCD command) is sent to the center facsimile. In operation 310, the CPU 10 transmits an option key input request command signal to a center facsimile. At this time, the central processing unit 10 of the center facsimile transmits the DCS to the remote facsimile, waits for a predetermined time in step 210, and checks whether an LCD command is received from the remote facsimile in step 211. Proceed is to display the option information on the LCD, which is the display of the OPE 20, and returns to step 210. In this case, if the LCD command is not received in step 211, the print command is received. If the print command is received, the CPU 10 controls the printer 70 to print option information and returns to step 210 in step 214. Goes. However, if the print command is not received in step 213, the process proceeds to step 215. If the option selection request key is input from the OPE 20, the process proceeds to step 216. If the option selection key is not input in step 216, if the option selection key is not input, the process returns to step 217 to search for the option selection key to be continuously input for the set time. In this case, when the option selection key is input, the CPU 10 transmits a corresponding key value corresponding to the option selection key to the remote facsimile. Then, the central processing unit 10 of the remote facsimile checks whether the option key value is received in step 311, and if the option key value is not received, proceeds to step 312 and searches for receiving the option key value for the set time. As a result, when the option key value is received in step 311, the process proceeds to step 313. The CPU 10 checks whether the option is stopped. If the option is stopped, the program is terminated. In step 314, the central processing unit 10 checks whether the received option key value is a valid value for the option number, and if it is not a valid value, returns to step 310 and sends an option key input request command, that is, an option number input request command to the center facsimile. . Here, the option number is, for example, 00 → DIAL, 01 → transmission speed, 02 → line compensation, or the like. However, if the option key value is a valid value, the central processing unit 10 sends an option input display command (LCD command) to the center fax in step 315 and proceeds to step 316. In step 316, the central processing unit 10 transmits the option key input request command signal to the center facsimile. At this time, the central processing unit 10 of the center facsimile waits for a predetermined time in step 210, and then checks whether an LCD command is received from the remote facsimile in step 211, and if the LCD command is received, proceeds to step 212 and displays the display unit of the OPE 20. Displays option information on the LCD and returns to step 210. In this case, if the LCD command is not received in step 211, the print command is received. If the print command is received, the CPU 10 controls the printer 70 to print option information and returns to step 210 in step 214. Goes.

However, if the print command is not received in step 213, the process proceeds to step 215 and checks whether the option selection request key is input from the OPE 20. If the option selection key is not input in step 216, if the option selection key is not input, the process returns to step 217 to search for the option selection key to be continuously input for the set time. In this case, when the option selection key is input, the CPU 10 transmits the corresponding key value corresponding to the option selection key to the remote facsimile in step 218. The option selection key is the actual option value, for example DIAL → 0: DP, 1: MF transmission speed → 0: 9600, 1: 7200, 2: 4800, 3: 2400, line compensation 0: 1.8K, 1 : 3.6K, 2: 7.2K Then, the central processing unit 10 of the remote facsimile checks whether the option value is received in step 317, and if the option value is not received, proceeds to step 318 and searches for receiving the option value for a set time. As a result, if the option value is received in step 317, the process proceeds to step 319. The CPU 10 checks whether the option value is valid, and returns to step 309 if the option value is not valid, and proceeds to step 320 if the option value is valid. By updating the received option value in the memory unit 30 to set the option value.

As described above, the present invention can remotely control the remote facsimile in the center facsimile regardless of the type of the facsimile by setting the option information of the remote facsimile in the center facsimile by the remote diagnostic control protocol between the center facsimile and the remote facsimile. This has the advantage of reducing after-sales service time and costs.
