Abstract

PURPOSE: To allow the facsimile equipment to cope with an unexpected fault accompanying a function expansion by revising an operation parameter stored in the facsimile equipment through the communication from a remote diagnostic center terminal equipment. CONSTITUTION: When a memory content read request is received from a remote diagnostic center terminal equipment, a CPU 6 returns data of a designated address of a memory 5 via a network control circuit 4, by which a state of the facsimile equipment is grasped. The diagnostic center sends operating parameters required to be revised, being new data such as a setting amount of an equalizer, operation, transfer speed of a modulation/demodulation circuit 3 and attenuation of an attenuator as a write request together with each address to the facsimile equipment, in which the parameters are revised. Furthermore, a recovery memory is stored in the memory 5 by the write request and an execution request allows the CPU 6 to execute the recovery program. Since it is not required to store a recovery program as to all expected faults to the memory 5 in advance, the memory capacity is saved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile device connectable to a communication terminal device in a diagnostic center installed in a remote place.

[0002]

2. Description of the Related Art Recent electronic devices are equipped with a large number of electronic components and have a complicated circuit configuration. Therefore, electronic devices often have a self-diagnosis function for analyzing the cause of a failure and recovering the failure early.

In addition to the self-diagnosis function described above, a communication terminal device such as a facsimile device can utilize its own communication function to perform a remote fault diagnosis by performing a fault diagnosis or a fault repair from a diagnostic center at a remote location or another communication terminal device.・ Has a failure repair function.

As shown in FIG. 5, a conventional facsimile apparatus is provided with a circuit 5 for diagnosing and repairing failures such as a scanning section / recording section 1, a communication data processing section 2, a modulation / demodulation circuit 3 and a network control circuit 4. It was

The operation of the above configuration will be described with reference to FIG. 6. The failure diagnosis / repair circuit 5 is operated by the diagnosis request notification from the diagnosis center (or another facsimile apparatus or the like) to operate the other circuits 1 to 4 and the like. The failure analysis is performed and the failure diagnosis result is notified to a diagnosis center or the like, or the operator of the facsimile device is notified. If the failure can be repaired, the diagnostic center or the like notifies the facsimile apparatus of the failure repair information or a failure repair processing request.
In addition, in FIG. 5, a broken line in the drawing shows a control line in the case of performing the failure diagnosis / repair, and a solid line in the drawing shows a control line in the case of the control unit 6 performing the normal communication control.

[0006]

However, according to such a configuration, the facsimile apparatus must be provided with a failure diagnosis / fault repair function in advance, so that the multifunctional apparatus has a problem that the facsimile apparatus becomes expensive. .

The above problems can be solved to some extent if the diagnosis / repair function is realized by a program, but in this case too, there is a problem that a large amount of memory dedicated to the program is required. Also, to program in advance,
It is difficult to extend the function later. In addition, there is a problem that the function cannot be expanded later because the programming is performed in advance.

In view of the above-mentioned problems of the conventional example, the present invention provides a facsimile apparatus which can realize a fine failure diagnosis / fault repair function without providing a large-scale diagnosis / repair function in the facsimile apparatus in advance. That is the purpose.

[0009]

In order to solve the above problems, the present invention has a communication control means for making a line connection with a communication terminal device installed in a remote place, a memory, and a memory stored in the memory. And a memory control means for controlling reading and writing of information, and when the operation parameter information is sent from the communication terminal device installed at the remote place, the program is stored in the memory based on the added address information. It is also stored.

Since data such as operation parameters stored in the memory provided inside the facsimile apparatus can be changed from the communication terminal apparatus installed at a remote place, an unexpected failure due to the function expansion of the facsimile apparatus can be prevented. Can also be dealt with.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a facsimile apparatus according to one embodiment of the present invention, and the same components as those in FIG. 3 are denoted by the same reference numerals.

In FIG. 1, 1 is a scanning unit / recording unit for reading an original image and recording the transmitted original image, 2 is a communication data processing unit for processing a transmission image signal and a reception image signal, and 3 is a transmission unit. A modulator / demodulator circuit that modulates an image signal or a received image signal, 4 is a network control circuit that controls a network with a diagnostic center to which the present facsimile machine is connected and other facsimile machines, and 5 is an operation parameter of the facsimile machine. A memory for writing or writing a diagnosis / restoration program, 6 is a function of reading data from the memory 5, writing data to the memory 5 and executing a program of the memory 5, and 7 is an overall control of the facsimile apparatus It is a control circuit for controlling.

The operation will be described below with reference to FIGS. FIG. 2 is an explanatory diagram when the diagnostic center grasps the state of the facsimile machine. First, a request for reading the memory contents is transferred from the diagnostic center to the facsimile apparatus with address information added thereto. In the facsimile apparatus, the request is read, written, and transmitted to the program execution function 6 via the network control circuit 4 and the control circuit 7, and the contents of the memory 5 are read. The read data is transferred to the diagnostic center via the network control circuit 4. In this case, when the diagnostic center designates an appropriate address and issues a read request, the data in the memory 5 is transferred, and the state of the facsimile apparatus at that time can be grasped.

Next, FIG. 3 shows a case where the diagnostic center changes the operating parameters of the facsimile machine. Here, the operating parameters refer to the set amount of the equalizer, the operation of the modulation / demodulation circuit, the transfer speed, the attenuation amount of the attenuator, etc., and are stored in the memory 5.

First, a memory write request is added from the diagnostic center to a facsimile machine with address information added, and then operation parameter information is transferred. In this case, assuming that the added address is the operation parameter storage address of the memory 5, the operation parameter of the memory 5 is changed.

Finally, FIG. 4 shows the case where the facsimile machine executes the program transferred by the diagnostic center. First, the diagnostic center sends a memory write request with address information added, and then sends the program. In the facsimile apparatus, the program sent to the added address in the memory 5 is written by the read / write / program execution function 6.

Next, when the program execution request is issued from the diagnostic center and the address of the program is specified, the reading, writing and program executing function 6 of the facsimile machine reads and executes the program. By combining this program execution with the state grasping of FIG. 2 and the operation parameter changing of FIG. 3, it is possible to realize failure diagnosis and failure repair of the facsimile apparatus.

If the memory 5 has a failure diagnosis / fault repair program built-in, the failure diagnosis / fault repair of the facsimile apparatus can be performed by transferring an execution request of the program from the diagnostic center.

[0019]

As described above, according to the present invention, the data such as the operation parameters stored in the memory provided inside the facsimile apparatus is changed based on the request from the communication terminal apparatus installed at the remote place. Therefore, it is possible to deal with an unexpected failure due to the function expansion of the facsimile apparatus, and it is possible to increase flexibility in repairing the failure of the facsimile apparatus.
