Description

TECHNICAL FIELD The present invention relates to an image communication system, and more particularly to a facsimile simultaneous command system in a simultaneous command system such as a disaster prevention radio.

(Prior Art) A facsimile simultaneous command system includes a command station connected by a wireless line and at least one terminal station.
The command station calls the terminal stations all at once through, for example, a wireless command line, and transmits image information from the command facsimile to the terminal stations. After the transmission is completed, the command station receives the quality of the reception result from each terminal station and confirms the transmission of the information. The conventional system includes a reception confirmation automatic return method in which the terminal station automatically returns the reception confirmation result, and a reception confirmation manual return method in which the terminal station manually returns the reception confirmation result.

The transmission format is the same in both systems, and when transmitting a simultaneous command, the commander designates the terminal station of the command destination on the simultaneous command console and instructs the simultaneous call. In response to the set instruction and information, the circuit switching device activates the terminal station which is the target of the command destination in the non-turning line by the simultaneous command control device.

In response to this, the simultaneous command receiving terminal device of each terminal station activates the reception facsimile, and when this responds automatically, the original set in the command facsimile is transmitted to the reception facsimile of the terminal station. In the case of the automatic reception confirmation return method, when the transmission of the document is completed, the circuit switching device sends a reception confirmation return instruction signal to the reception facsimile to confirm the reception status. The reception facsimile monitors the disorder of the received image during reception, and when there is the disorder of the reference value or more, when receiving the reception confirmation return instruction signal, it returns the "confirmation impossible" signal. If it is normal, a "ready" signal is returned. The reception confirmation result is displayed to the orderer.

In the reception confirmation manual return system, a reception confirmation device is provided in the terminal station, and when the reception confirmation instruction signal is received by this device, an audible signal is generated to notify the commandee. The commandee visually confirms the received image and operates the confirmation button of the reception confirmation device to return "confirmable" or "confirmable".

(Problems to be Solved by the Invention) As is well known, in facsimile transmission, the received image may be disturbed due to, for example, disturbance due to the propagation state of radio waves or the influence of weather conditions such as thunderstorms. In the conventional facsimile simultaneous command system, in the case of the reception confirmation automatic return method, if the reception disturbance is equal to or larger than the reference value, a "confirmation impossible" signal is returned even if the disturbance is visually readable. Therefore, there was a problem that the commander had to resend the individual communication to the terminal station that returned "not confirmed". This is a troublesome operation for the commander, especially in an emergency, and the radio wave propagation situation is often bad at such time. Further, the reception confirmation manual return method has a problem that the command receiver must meet the reception of the manuscript at the terminal station.

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the above-mentioned problems and to provide a facsimile simultaneous command system capable of smoothly confirming a facsimile simultaneous command.

(Means and Actions for Solving the Problems) In order to solve the above problems, the present invention includes a command station for instructing a simultaneous command of a facsimile and at least one terminal station connected to the command station, In the facsimile simultaneous command method, in which a command is sent from the station to the terminal station and at least the command station sends the facsimile to the terminal station, the command station automatically returns a facsimile reception confirmation response from the terminal station for the simultaneous command to the terminal station. Specify whether to send or manually return, the terminal station monitors the reception disturbance when receiving a facsimile from the command station, and if the reception disturbance exceeds a predetermined standard, specifies the automatic return from the command station In response to the request, the terminal station returns a notification to that effect, and when the command station specifies manual return, the terminal station manually receives the reception confirmation result for facsimile reception. To be sent back to
When the reception confirmation result is manually input, it is returned to the command station, and the command station displays the reception confirmation result returned from the terminal station.

At 22, the image represented is reproduced on the recording medium as a visible image. The command reception facsimile 22 monitors the facsimile signal being received, and when it detects a disturbance of a standard value or more of the image, stores it.

The circuit switching device 12 sends a confirmation return instruction signal from the simultaneous instruction control device 13 according to the confirmation return method set by the selection identification button 14 of the simultaneous instruction console 11. When the simultaneous command receiving terminal device 21 receives the confirmation return instruction signal, it performs an operation according to the content thereof. When the confirmation return instruction signal instructs automatic return, the broadcast receiving terminal device 21 automatically returns the facsimile reception result stored therein. If the image disturbance is above the standard value, the reception confirmation inability signal is returned, and if the disturbance above the reference value is not detected, the reception confirmation signal is returned.

Further, when the manual return is instructed, the simultaneous command receiving terminal device 21 first causes the buzzer 23 of the order reception facsimile machine 22 to ring to prompt the order receiver to return the confirmation. The commandee then visually recognizes the image output from the facsimile 22 and operates the reception confirmation button 24 according to the result of the visual recognition. In response to the operation of the reception confirmation button 24, the simultaneous command receiving terminal device 21 returns a reception confirmation enable signal indicating that the received image can be decoded or a reception confirmation disable signal indicating that there is an unreadable or difficult part. .

Causes the simultaneous command display device 17 to display the result indicated by the reception confirmation signal. Thereby, the commander can know the reception confirmation result of the facsimile transmission for each terminal station 20. The commander may end the simultaneous command if all the terminal stations 20 are “acceptable for reception”. If there is a terminal station 20 in which "unable to receive" is displayed, the terminal station 20 can be individually designated by the simultaneous command operation console 11 to retransmit a facsimile.

(Effects of the Invention) As described above, in the present invention, the command station can specify whether the confirmation of the reception result at the terminal station of the facsimile communication by the simultaneous command is automatically returned or manually returned. For example, when it is judged that the priority or urgency of the broadcast command information is high, or when the transmission condition is bad such as heavy rain, manual return is performed, and when it is determined that the priority or urgency of the broadcast command information is low. If it is judged that the transmission status is good, such as no thunderstorm or thunderstorm, specify automatic return. Therefore, the orderer can select an appropriate method for confirmation of reception according to the status of the simultaneous order. Generally, human visual recognition has a wide allowable range. Therefore, even if the received facsimile detects an image disturbance that exceeds the allowable standard, a visible image is often received. According to the present invention, in such a situation, a smooth confirmation can be performed by designating a manual return method for reception confirmation. Therefore, in the facsimile simultaneous command system according to the present invention, confirmation of the facsimile simultaneous command can be performed smoothly.

For example, if the priority of the facsimile simultaneous command is high and the transmission status is bad, the manual method is instructed for confirmation of reception, and if the transmission status is good or the urgency is low, the automatic confirmation method may be specified. Good. Further, according to the present invention, the reception confirmation apparatus, which was required in the conventional reception confirmation manual return system, is unnecessary.
