Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an image information registration processing method performed between a center side device and a plurality of image information input/output devices.

[Prior art]

One of this type of image information registration processing method is one that aims to always register and provide the latest image information by constantly updating the image information registered in the center side device. Specifically, there is a case where a weather map, which is weather information, is registered.

However, in the conventional image information registration processing method, since there is only one buffer memory for registration in the center side device, when there is a request from the terminal device to output the registered image information, the corresponding While the request is being processed, update registration cannot be performed even if the latest information to be updated is prepared. Especially when requests are made continuously, it cannot be updated forever.

On the other hand, while image information update is being registered, an output request cannot be made, which is contrary to the requester's need to obtain the latest information as soon as possible.

[Summary of the invention]

The present invention has been made in view of the above-mentioned problems, and its purpose is to provide an image information registration process that is capable of constantly and effectively registering updates of the latest image information and requesting the output of the latest image information. It's about getting the formula.

In order to achieve such an object, the present invention includes three buffer memories, a registration backup memory, a first request backup memory, and a second request buffer memory, in the center side device, and is capable of updating image information. At the time of registration, the image information is temporarily stored in the registration buffer memory, and then transferred to the one where the older image information is stored of the two request buffer memories and rewritten, and the image information output request is made. In this case, 17f is set so that reading is performed from the one of the two requested backup memories that stores new image information.

〔Example〕

The present invention will be described in detail below along with examples.

FIG. 1 is a block diagram showing one embodiment of the present invention. In the center side device 10, a storage device 12 and a registration processing device 14 are provided. The storage device 12 has times 816,
A facsimile machine 20.22, which is an image information input/output terminal device, is connected via 18. The storage device 12 is
Although this device has a large number of files for storing image information and performs so-called storage/exchange processing, this embodiment mainly utilizes the function of the center side device 10 as an image information input/output means.

FIG. 2 is a block diagram showing the internal configuration of the registration processing device 14 of FIG. 1. The storage device interface 24 inputs and outputs information to and from the storage device 2 via connection lines 26 and 28, and its output lines 27 and 29 extend to the registration processing section 30 and the request processing section 32. The interface 24 also accepts input from the request processing section 32 via the connection line 31.

The buffer memory section 34 is for storing image information, and includes a registration panzer memory 36 and a request buffer memory 3.
Contains 8.40. Input/output line 3 of registration buffer memory 36
3.35 both extend to the registration processing section 30. Input lines 37 of the two request buffer memos IJ 38 , 40 extend to the registration processing unit 30 , and output lines 39 extend to the request processing unit 32 .

The request buffer memory management unit 42 has a split buffer memory I.
) 3 B and 4 Q is monitored to see which of the stored contents is newer, and input/output lines 41 and 43 extend to the registration processing section 30 and the request processing section 32, respectively.

Next, the operation of this embodiment will be explained. Facsimile machine 2
0 to a registration command (
When the image information to be registered for a report and update is input, it is transmitted to the storage device 12 via the line 16. When the storage device [12] receives registration command information and image information, it transmits these information to the registration processing device 14.

In the registration processing device 14, the storage device interface 24
At , information from the storage device 12 is received, and it is determined whether it is a registration process or a request process, which will be described in detail later. Now, based on the registration command information (1), it is identified that the process is a registration process, and image information is output to the registration processing section 30.

The registration processing section 30 stores input/print information in the registration buffer memory 36, except when a preceding registration process is being performed.

When the storage is completed, the registration processing unit 30 inquires the request buffer memory management unit 42 and stores the request buffer memory 3tl.
, 40 is the oldest. now,
The request buffer memory 38 has the old content (image information)
If so, it is checked whether a request process, which will be described later, is being performed on the memory 38'. Registration processing unit 30
transfers the image information from the request buffer memory 381' from the registration buffer memory 36 immediately if no request processing has been performed on this request buffer memory 38, or immediately after the request processing is completed if the request processing has been performed. The information will be deleted.

Note that the information in the request buffer memory management unit 42 is updated when the transfer to the request buffer memory 38 is completed. That is, the transfer just made will cause the request buffer memory 38 to
The image information stored in the image information is now updated to indicate that it has become new image information.

Next, a case (request processing) in which registered image information is read out and output to a facsimile device will be described.

When request command information is input from the facsimile machine 22, this information is transmitted to the storage device 12 via the line 1B. When the storage device 12 receives the request command information, it further transmits this information to the registration processing device 14 .

In the registration processing device 14, the storage device interface 24
, receiving request command information from the storage device 12;
Based on this information, it is identified that it is a request process, and the information is further output to the request processing section 32.

The request processing unit 32 inquires of the request buffer memory management unit 42 which contents of the request buffer memory 38 and 40 are new. Now, assuming that the contents of the request buffer memory 40 are new, the request processing unit 32 reads the contents of the memory 40 and outputs it to the storage device interface 24. This image information is further transferred to the storage device 12 and finally output to the facsimile device 22 via the line 18.

In this embodiment, two terminal devices are used for simplicity, but it goes without saying that more terminal devices may be provided.

Furthermore, although this embodiment has only one set of buffer memories consisting of one registration buffer memory and two request backup memories, a large number of sets are provided and a code number is assigned to each set. Then, by adding code number information to each of the registration command information and image information or request command information, the image information registration processing method of the present invention can be applied to various types of image information.

〔Effect of the invention〕

As explained above, according to the image information registration processing method of the present invention, a registration buffer memory is provided in the center side device. 3, a first request buffer memory and a second request buffer memory.
When registering an update of image information, the image information is temporarily stored in the registration buffer memory and then transferred to the one of the two request backup memories that stores the older image information. When there is a request to output image information, the system reads out the one that stores the new image information from the two request backup memories, so it is possible to register the update of the latest image information. Also, a request for outputting the latest image information can be made effectively at all times.
