Description

[Detailed Description of the Invention] Industrial Application Field The present invention automatically transmits a manuscript with the same content (hereinafter referred to as a broadcast message) to multiple destinations (destinations) in facsimile communication, and The present invention relates to a so-called facsimile storage and broadcasting device that automatically performs retransmission processing multiple times when transmission is impossible.

Conventional technology In recent years, with the increasing use of facsimile communication,
Facsimile storage and broadcasting devices are becoming increasingly used.

By the way, this type of conventional facsimile storage/broadcasting device temporarily stores broadcast messages received from terminals and processes broadcast communications according to the control contents of the messages. Sometimes, if the terminal device at the other end enters an abnormal state due to power off, recording paper out, busy, or line abnormality, it will be determined that transmission is impossible and the retransmission process will be repeated multiple times. It's summery.

In this retransmission process, the interval until re-calling was always constant. In other words, retransmission is started after waiting for a predetermined fixed interval (time).

Problems to be Solved by the Invention In short, conventional facsimile storage and broadcasting devices always maintain a constant interval between re-calls, even though the recovery time from the cause of a transmission failure varies depending on the cause. It was set to .

As a result, retransmission before the cause of the transmission failure has been recovered will cause another transmission failure, etc.
An unfavorable problem occurred in terms of line usage efficiency.

Furthermore, if there is a limit to the number of re-calls (generally three times in the past), there is also the problem that the broadcast message ends up not being delivered.

Therefore, the present invention makes it possible to finely determine the calling interval by taking into account the causes of failure to send, thereby improving line usage efficiency and reducing the rate of non-delivery of broadcast messages. The purpose is to provide a facsimile storage and broadcasting device.

Means for Solving the Problems In order to achieve the above object, the facsimile broadcasting device of the present invention includes an image information memory for recording messages transmitted from each broadcast request source terminal, and a video information memory for recording the messages from the image information memory. A transmission control unit that performs readout and broadcast communication to a destination terminal, and performs retransmission processing multiple times when communication to the destination terminal is impossible, and retransmission processing depending on the cause of transmission failure. and a call interval memory which stores in advance the call intervals in the call interval memory, and when performing retransmission processing, determines the reason why the call was not possible and reads out the corresponding call interval from the call interval memory, The retransmission process to the destination terminal is performed based on the read call interval.

Effect With the above configuration, it is possible to re-call at an interval that takes into account the recovery time determined by the cause when transmission was impossible, and as a result, by re-transmitting before recovery. This prevents transmission failure from occurring again and makes it possible to use the line efficiently. In addition, since the calling interval for each cause in the memory is preset within the facsimile storage and broadcasting device, no special communication procedures are required.
The above effects can be obtained with a fairly simple configuration.

Embodiment FIG. 1 is a schematic configuration diagram showing an embodiment of a broadcast communication system including the facsimile storage and broadcast device of the present invention. In the figure, FAX ₁ , FAX _{2 ...} A dual-purpose facsimile terminal device (part of which may be used exclusively for reception), S is an exchange connected to each facsimile terminal device FAX ₁ to FAX _o via a facsimile communication line, and M is an exchange connected to this exchange S. This is a facsimile storage and broadcasting device (hereinafter simply referred to as a broadcasting device) of the present invention connected via a plurality of receiving and transmitting lines (two lines in the illustrated example). Furthermore, M _IN is the connection end of the receiving line,
M _OUT is the connection end of the transmission line.

In this embodiment, a known broadcast instruction mark sheet (of course, an OCR sheet or the like may also be used) is used as a means for inputting control information for controlling broadcast communication.

As shown in FIG. 1, the broadcasting device M includes a facsimile reception control section 1 (which increases or decreases depending on the number of lines) that is in charge of facsimile reception control, and a reception channel control section 2 that controls the entire reception channel. a message reception management unit 3 that manages reception of broadcast messages;
A message storage section 4 that stores the contents of broadcast messages; a message management information storage section 5 that stores and manages information other than the contents of broadcast messages, such as reception date and time; Message distribution management unit 6 to extract
, a transmission channel control unit 7 that controls the entire transmission channel, a facsimile transmission control unit 8 that controls the transmission of the broadcast message to the other party, and a transmission channel control unit 7 that controls the entire transmission channel, a facsimile transmission control unit 8 that controls the transmission of the broadcast message to the destination, and a broadcast command mark sheet that is input together with the broadcast message. In addition to being equipped with a mark sheet recognition unit 9 that recognizes control information necessary for broadcast communication and a terminal information storage unit 10 that stores terminal information (described later) in advance, it is also equipped with a mark sheet recognition unit 9 that recognizes control information necessary for broadcast communication. A call interval storage unit 11 is used to store the call interval (time) according to the situation when the call was not received (the reason why the transmission was not possible) and the number of re-calls, and a broadcast broadcast from the call interval storage unit 11 At the time of re-call processing, which is determined based on the calling pattern number (pre-stored in the terminal information storage unit 10 as described later), the cause of the failure to transmit, and the number of re-calls when transmission was not possible. The configuration includes a calling interval control section 12 that derives the calling interval.

The terminal information storage unit 10, as shown in FIG.
A plurality of storage sections 10a, 10b, .

Each storage unit 10a, 10b, ... 10n is a storage unit for terminal numbers (each FAX ₁ to FAX _o number),
Terminal name (distribution destination name, management department name, etc.) storage section,
It is comprised of a telephone number storage section, a calling pattern number storage section, etc., and each of these storage sections specifically stores and manages information on the destination of the broadcast communication.

The destination information in each of the storage units 10a, 10b, .
are incorporated into each.

In particular, the calling pattern number (destination information) in the calling pattern number storage section is taken into the calling interval control section 12, as will be described later.

As shown in FIG. 3, the calling interval control unit 11
The same number of storage units 11 _a ,
11 _b , . . . 11 _o are arranged in series, and each of these storage units can be sequentially searched.

Each storage unit 11 _a , 11 _b , . . . 11 _o is stored according to the number of re-calls and the cause of failure in broadcast transmission (for example, classified as busy, line abnormality, communication error, etc.). The calling interval is determined accordingly.
N ₁₁ to _{N on} are stored in advance for each calling pattern number.

Note that this call interval can be modified more precisely by subdividing the number of re-calls and the cause of failure. This enables more efficient broadcast communication.

Next, the operation of the broadcasting device M having the above configuration will be explained.

Now, if you set the broadcast command mark sheet and broadcast telegram to FAX ₁ shown in Figure 1 and perform the sending operation, these telegrams will be received by facsimile via exchange S according to the general-purpose facsimile transmission procedure. The information is received by the control unit 1 as image information.

The received image information is input line by line to the message storage unit 4 and message management information storage unit 5 via the reception channel control unit 2 and message reception management unit 3, and at the same time is input to the mark sheet recognition unit 9. Ru.

Based on the input data input to the mark sheet recognition section 9, the recognition section 9 detects the presence or absence of a mark, that is, the presence or absence of control information necessary for broadcast communication. When the existence of this control information is recognized, the terminal number information of the other party is extracted from this control information,
This terminal number information is compared with each piece of information (terminal number) in the terminal information storage section 10.

As a result of the comparison, if it is determined that the two pieces of information do not match, information indicating that the information is unregistered is returned to the originating party.
If a match is recognized, broadcast communication enable information is output from the mark sheet recognition section 9 to the facsimile reception control section 1.

The facsimile reception control unit 1 that has received this broadcast communication enable information transfers the broadcast message to the message reception management unit 3 via the reception channel control unit 2. Then, the management unit 3 stores the content of the broadcast message in the message storage unit 4.
At the same time, information other than the message contents, such as the reception date and time, is accumulated in the message management information storage section 5. At this point, the series of receiving operations ends.

When the need for transmission arises, the message distribution management section 6 retrieves terminal information (terminal number, terminal name, telephone number, etc.) of the destination from the terminal information storage section 10, and
This is transferred to the facsimile transmission control section 8 via the reception channel control section 7. Thereafter, the broadcast telegrams are transmitted sequentially or all at once from the transmission control unit 8 to the destinations (FAX ₂ to FAX _o ) according to the transmission procedure based on the broadcast communication control unit.

On the other hand, when transmission is not possible, the transmission control unit 8
The reason why the message could not be sent (busy, line abnormality, communication error, etc.) is notified to the message distribution management section 6 via the transmission channel control section 7.

The message distribution management unit 6 further examines the reported cause,
The information is transmitted to the calling interval control unit 12.

Upon receiving this, the calling interval control unit 12 extracts the calling pattern number of the destination from the terminal information storage unit 10, and also extracts the calling pattern number of the called party from the terminal information storage unit 10, and also extracts the calling pattern number of the called destination from the terminal information storage unit 10, and also extracts the calling pattern number from the calling interval storage unit 11 corresponding to the calling pattern number. 1
1 _a ), the call interval (for example, N ₂₂ ) determined by the cause of the failure to send and the number of re-calls.
, and suspends transmission for that calling interval (time).

Thereafter, the call interval control section 12 supplies a re-call start signal to the message distribution management section 6. From then on,
Following the above procedure again, the broadcast telegram is sent to the other party's destination.

Effects of the Invention As is clear from the above explanation, the present invention has a call interval memory that stores in advance the call interval in retransmission processing according to the cause of failure of transmission, and performs retransmission processing. In this case, the cause of the failure to transmit is determined, the corresponding call interval is read from the memory, and retransmission processing to the destination terminal is performed based on the read call interval. As a result, it is possible to re-call at a call interval that takes into account the recovery time determined by the cause of failure in transmission, and as a result, it is possible to prevent transmission failure from occurring again due to retransmission before recovery. However, it is possible to obtain excellent effects such as improving line usage efficiency, reducing the undelivered rate of broadcast messages, and improving the efficiency of the entire system. In addition, since the calling interval for each cause in the memory is preset within the facsimile storage and broadcasting device, the above effects can be obtained with a simple configuration without the need for special communication procedures. Become.
