Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an image communication system, and particularly to a facsimile simultaneous command system in a simultaneous command system such as a disaster prevention radio system.

(Prior Art) A facsimile simultaneous command system includes a command station and at least one terminal station connected via a wireless line.

The command station calls the terminal stations all at once from, for example, a wireless command line, and transmits image information to the terminal stations from a command facsimile. After the transmission is completed, the command station receives (,
Receive the quality of the T result and confirm the transmission of information. Conventional systems include an automatic reception confirmation return method in which the terminal station automatically returns the reception confirmation result, and a manual reception confirmation return method in which the terminal station returns the result manually.

The transmission format is the same for both types, and when transmitting a simultaneous command, the commander specifies the terminal station of the command light on the simultaneous command console and instructs simultaneous paging. In accordance with the set instructions and information, the line switching device activates the terminal stations that are the targets of the command light over the wireless line using the simultaneous command and control device.

In response to this, the collective command receiving terminal device of each terminal station activates the command receiving facsimile, and when this automatically responds, the manuscript set in the command facsimile is transmitted to the command receiving facsimile of the terminal station. In the case of the reception confirmation automatic return method, when the transmission of the document is completed, the single-line switching device sends a reception confirmation return instruction signal to the receiving facsimile to confirm the reception status. The receiving facsimile monitors the received image for disturbances during reception, and if the disturbance exceeds a standard value, it returns a "confirmation not possible" signal upon receiving the reception confirmation return instruction signal. If normal, a "receivable" signal is returned. This reception confirmation result is displayed to the dispatcher.

In the manual reception confirmation return method, a terminal station is equipped with a reception confirmation device, and when this device receives a reception confirmation instruction signal, it generates an OT audible signal to inform the recipient of the fact. The recipient visually confirms the received image, operates the confirmation button for wearing the reception confirmation, and returns "confirmation possible" or "confirmation not possible."

(Problems to be Solved by the Invention) As is well known, in facsimile transmission, disturbances may occur in received images due to disturbances due to radio wave propagation conditions or weather conditions such as thunderstorms.

In the conventional facsimile simultaneous command system, if the reception confirmation automatic return method is used, if the reception disturbance exceeds the standard value,
Even if the disturbance is visible to the naked eye, a "confirmation not possible" signal will be returned. Therefore, there was a problem in that the dispatcher had to resend individual communication to the terminal station that returned "confirmation not possible". This is a troublesome operation for the dispatcher, especially in times of emergency, and radio wave propagation conditions are often poor at such times. In addition, the manual return confirmation method has a problem in that the recipient must be present at the terminal station to receive the document.

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile simultaneous command system that eliminates the above-mentioned problems and allows smooth confirmation of facsimile simultaneous commands.

[Means and operations for solving the problems] In order to solve the above-mentioned problems, the present invention includes a command station for instructing simultaneous facsimile commands, and at least one terminal station connected to the command station, In the facsimile simultaneous command method, in which a central station issues a simultaneous command to terminal stations and at least facsimile transmission is performed from the command station to the terminal station, the command station receives a confirmation response from the terminal station to confirm the reception of the facsimile in response to the simultaneous command to the terminal station. Specify whether to return the fax or manually return it, and the terminal station, when receiving a facsimile from the command station,
It monitors reception disturbances, and if the reception disturbance exceeds a predetermined standard, it responds to the command station's automatic return designation and sends a notification to that effect to the command station, and the terminal station specifies manual return from the command station. Then, regarding the reception of the facsimile, a message is displayed to manually send the reception confirmation result back to the command station, and once the reception confirmation result is entered manually, it is sent back to the command station, and the command station Displays the reception confirmation result returned from the terminal station.

(Embodiment) Next, an embodiment of the facsimile simultaneous command system of the present invention will be described with reference to the accompanying drawings.

The facsimile simultaneous command system of this embodiment is composed of a single command station 10 and at least one terminal station 20 connected by a command line 18, and the terminal stations 20 are activated by a simultaneous command from the command station 10. This is a system in which images are transmitted simultaneously by facsimile. This is advantageously applied to a simultaneous command system such as a disaster prevention radio, for example.

It has a function of identifying the confirmation result from 0 and displaying it on the simultaneous command display device 7. The confirmation return instruction signal includes an "automatic return instruction" signal that requests the terminal station 20 to automatically return the facsimile reception result, and an "auto return instruction" signal that requests manual return.
There is a "manual return instruction" signal.

The simultaneous command display device 17 is a display device that is connected to the line switching device 12 and visually and/or audibly displays the response status of the terminal station 20 and the reception confirmation result of facsimile transmission.

In this embodiment, the simultaneous command control device 13 is a device that transmits and receives signals to and from the simultaneous command terminal equipment 21 of the terminal station 20 via a wireless command line 18. This activates the terminal station 20 to receive the order in response to the selection signal transferred from the simultaneous command console 11, confirms the reception response, sends and receives facsimile signals, and sends the confirmation return instruction signal (PI, confirmation result). It has functions such as receiving.The line 18 is not limited to wireless, and may of course be wired.

The simultaneous command receiving terminal device 21 of the terminal station 20 is a device that transmits and receives information between the command receiving facsimile 22 and the simultaneous command control device 13 via the transmission/reception line 18 . A command receiving facsimile 22 is connected to the simultaneous command receiving terminal device 21 . The order receiving facsimile 22 is a facsimile receiving device that automatically responds when activated by the simultaneous command receiving terminal device 21, visualizes the facsimile signal sent from the command station IO, and reproduces the image on a recording medium. be. Of course,

4 are provided. Of course, it may have a visual display function to remind visual confirmation. The order receiving facsimile 22 also has a function of constantly monitoring the received facsimile signal and detecting disturbances in the image exceeding a standard value. The order receiving facsimile 22 stores the presence or absence of image disturbance exceeding a standard value, and when instructed by the command station 10 to automatically return the reception result, sends a signal indicating the presence or absence of image disturbance, that is, a reception confirmation signal. It has the function of sending it back. Also.

When manual return is designated, the buzzer 22 is sounded and a reception confirmation signal is returned in response to the operation of the reception confirmation button 24. The reception confirmation signal indicates the detection of image disturbance exceeding the standard value.
It consists of either a "reception confirmation not possible" signal, or a "reception confirmation possible" signal 1 indicating that no disturbance exceeding a standard value has been detected.

Next, the operation of this embodiment will be explained. When issuing a simultaneous command, the commander operates the terminal designation button and the simultaneous command button 14 on the simultaneous command operation console 11, specifies the terminal stations 20 to be subjected to the simultaneous command, and activates the simultaneous command. At that time, the selection identification button 15 is operated to specify the return method of the reception result.

The simultaneous command operation console 11 calls the line switching device 12 according to the settings of these buttons, and the line switching device 12, which sends out selection signals according to the settings, calls the simultaneous command and control device 13 in response. to start. This activation signal is transmitted to the order receiving facsimile 22 via the simultaneous command control device 13, command line 18, and simultaneous command receiving terminal device 21. In response, the order receiving facsimile 22 sends a response signal back to the simultaneous command control device 13, and the line switching device 12 sends a response signal to the called terminal station 20.
The response results are displayed on the simultaneous command display device 17.

The dispatcher operates the facsimile transmission start button 14 according to the response status of each terminal station 20. In response to this, the line switching device 12 connects the instruction facsimile 16 to the simultaneous instruction control device δ13 as shown in the figure, and causes the facsimile transmission to be performed. This facsimile signal is sent to the simultaneous command control device 1.
3-Command line 18-Received by the command receiving facsimile 22 via the simultaneous command receiving terminal device 21, and the image it represents is reproduced as a visible image on a recording medium. The order receiving facsimile 22 monitors the facsimile signal being received, and if it detects a disturbance in the image that exceeds a standard value, it stores it.

The line switching device 12 sends out a confirmation return instruction signal from the simultaneous command control device 13 in accordance with the confirmation return method set by the selection identification button 14 on the simultaneous command console 11 . When the simultaneous command receiving terminal unit 521 receives the confirmation return instruction signal, it performs an operation according to the contents thereof.

If the confirmation return instruction signal instructs automatic return, the simultaneous reception terminal device 21 automatically returns the facsimile reception results stored therein. If there is an image deviation greater than the standard value, a signal indicating that the reception confirmation is not possible is returned, and if no disturbance greater than the reference value is detected, a signal indicating that the reception confirmation is possible is returned.

Further, if manual return is instructed, the simultaneous command receiving terminal device 21 first responds to the buzzer 23 of the order receiving facsimile 22.
sound to prompt the recipient to confirm and return the item.

There, the recipient visually confirms the image output from the facsimile 22 and operates the reception confirmation button 24 according to the result of the visual confirmation. In response to the operation of the reception confirmation button 24, the simultaneous command reception terminal device 21 returns a reception confirmation OK signal indicating that the received image can be deciphered, or a reception confirmation impossible signal indicating that there are parts that are impossible or difficult to decipher. .

These reception confirmation signals are transmitted from the line 18 and received by the simultaneous command control device 13 of the command station 10. The line switching device 12 causes the simultaneous command display device 17 to display the result indicated by the reception confirmation signal. This allows the dispatcher to
It is possible to know the reception confirmation result of facsimile transmission for each 0. The commander may end the simultaneous command if all the terminal stations 20 are "receiving confirmation possible." If there is a terminal station 20 that is displayed as "unreceivable," it is possible to individually designate that terminal station 20 on the simultaneous command console 11 and resend the facsimile.

(Effects of the Invention) As described above, in the present invention, the command station can specify whether confirmation of the reception result at the terminal station of facsimile communication by simultaneous command is to be returned automatically or manually. Therefore, the dispatcher can select an appropriate reception confirmation method according to the situation of the simultaneous command. Generally, human visual recognition ability has a wide permissible range. Therefore, even if an image disturbance exceeding the permissible standard is detected in the receiving facsimile, a visually recognizable image is often received. According to the present invention, in such a situation, by specifying the reception confirmation manual return method, smooth confirmation is possible. Therefore, in the facsimile simultaneous command system according to the present invention, confirmation of the facsimile simultaneous command can be smoothly performed.

For example, if the priority of a simultaneous facsimile command is high and the transmission condition is poor, you can specify the manual method for reception confirmation, and if the transmission condition is good or the degree of urgency is low, you can specify the automatic confirmation method. good. Further, according to the present invention, a reception confirmation device, which was necessary in the conventional manual reception confirmation return method, is not necessary.
