The present invention provides a line control device including a switch matrix that interconnects a first line group connected to a plurality of information supply sources and a second line group connected to a plurality of information receiving ends. , a control means for opening and closing the cross points of this switch matrix is provided, and this control means includes a clock means for generating time information, and a control means for monitoring this time information and opening and closing a predetermined cross point at a specified time. The invention is characterized by comprising a means for performing the same.

[Effect]

By monitoring the time information generated by the timekeeping means with the control means and automatically opening and closing by controlling predetermined cross points at specified times, operator operations are not required and incorrect connections caused by operational errors are avoided. can be excluded.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a line control device according to an embodiment of the present invention. In FIG. 1, facsimile transmitters 101 to
Information from line group 20. ~20. , switch matrix 30 and line groups 401-40 to facsimile receiver 50. ~50. ．． are connected to each.

Here, the feature of the present invention is the switching/closing connection portion of the Swiss/Sochi element shown by the dashed line. That is, the control circuit 60 is connected to the switch matrix 30. In the control pan circuit 60, a microprocessor 61 connects the crosspoint 30. , ~30ffi, , and a program memory 62 in which time information indicating the opening and closing times of individual cross points are stored, a random access memory 63, and a programmable input/output circuit 64 are connected to the microcontroller via a data bus 65. It is connected to processor 61. Time information from clock circuit 70 is connected to microprocessor 61 via programmable input/output circuit 64 and data bus 65.

A control signal P is connected from the programmable input/output circuit 64 to the crosspoint 31 where this time information matches the opening/closing time of the program memory 62, and opening/closing control is performed. In the case of manual operation, a control signal P from the operation panel 80 is connected to the cross point 31 via the programmable input/output circuit 64 to perform opening/closing control.

The operation of the line control device having such a configuration will be explained. In FIG. 1, cross points 301 . 30ffi, . . . , the opening/closing is controlled by the signal PII-P, . . . . The clock circuit 70 generates time information of hours, minutes, and seconds, and notifies the microprocessor 61 of the time information. The program memory 62 stores a program for controlling the opening/closing of the cross points 31.1 to 31□ of the switch matrix 30, and time information indicating the opening/closing time of each cross point 31. The microprocessor 61 executes the clock circuit 70 according to the microprogram in the program memory 62.
By sequentially reading the time information from , automatically controls line connection. The operation panel 80 is used to manually open and close each crosspoint 31, and is composed of a line switch corresponding to each crosspoint 31 and an automatic/manual changeover switch. When the automatic/manual changeover switch indicates "auto", line control operation is performed based on time information, but when it indicates "manual", the line control operation is performed by the operator's line switch operation regardless of time information. A control action is performed. In other words, automatic
When the manual switch indicates "manual", the crosspoint 31 corresponding to the pressed line switch is connected.

The device of the present invention was implemented in a device that periodically exchanges a plurality of pieces of information via a dedicated facsimile line. -For example, it has been used to save labor by allowing news aggregators or distributors to access news sources at predetermined times or to transmit news for distribution.

〔Effect of the invention〕

As explained above, the present invention sets the line connection and disconnection times in advance in the program memory in the control circuit, constantly monitors time information from the clock circuit, and automatically controls the line when the specified time arrives. By doing so, there is an excellent effect of eliminating the need for operator operations and at the same time eliminating erroneous connections caused by operator errors.
