ステム装置を提供することを目的とする。By the way, since the switching information and the communication information constituting the transmission signal are constituted by digital signals having the same form, it is not possible to distinguish between the forms. Therefore, when a part of the communication information includes information having the same expression as the switching information, the switching information receiving unit 15 switches the information having the same expression as the switching information included in the communication information in the transmission signal to the original switching. Inconveniently, communication information is sent to a receiving device that should not be transmitted, and communication information is not sent to a receiving device that should be originally sent, and the switching information is erroneously determined and information is sent to a receiving device that should not be sent. Occurred. Therefore, in order to avoid the above-mentioned problem, the communication information is subjected to a use restriction such as not using information expressed in the same manner as the switching information, so that the communication information is correctly transmitted to the receiving device. Therefore, a transmission signal composed of a binary digital signal having high transmission efficiency cannot be transmitted from the information transmission device 2 as it is, and is converted into a transmission signal that does not cause erroneous determination of the switch. Conversion processing was required. For this reason, there has been another inconvenience that the cost associated with the installation of the conversion processing device, the time required for the conversion process, and the time required for the transmission are increased. The present invention has been made in order to solve such a problem in the related art, and even if a transmission signal constituted by a binary digital signal is processed without modification, a plurality of transmission signals can be used as they are. It is an object of the present invention to provide a communication switching system device that can separately transmit to a receiving device.

FIG. 1 is a block diagram of a communication switching system device according to one embodiment of the present invention. The same reference numerals are given to portions which are the same as or can be regarded as the same as those in the conventional example, and redundant description thereof will be omitted. As shown in the figure, in the present embodiment, a switching request transmitting unit 23 is newly provided in the output stage of the information transmitting device 2, and a switching request confirming unit 14 is newly provided in the input stage of the switching device 1. FIG. 2 is a schematic diagram illustrating a configuration of a transmission signal transmitted from the information transmission device 2. As shown in FIG. 2, a switching signal is transmitted prior to the switching information at the head of the transmission signal. The operation of the embodiment will be described below. The switching request transmitter 23 generates a switching signal composed of a specific wide-width rectangular wave and outputs it to the head of the transmission signal. The switching request confirmation unit 14 checks the initial signal pulse width of the transmission signal received by the switching device 1 and confirms that the switching signal has a width within a predetermined range. As a result, the switching information receiving unit 15 receives the switching information added by the information transmitting unit 22, checks the contents thereof, determines which of the receiving devices 3 and 4 should be sent, and switches the result. The information is transmitted to the control unit 16. The switching control unit 16 controls the switching operation of the A switch 11 or the B switch 12 according to the received determination information. The switching information receiving unit 15 receives the switching information, checks its contents, and transmits the determination information, and thereafter stops the receiving operation. Therefore, even if a part of the communication information includes information having the same expression as the switching information, the switching information receiving unit 15 does not receive the information.
Can be prevented from erroneously determining information having the same expression as the switching information included in the communication information as the switching information. As described above, a switching signal composed of a specific wide-width rectangular wave is added before transmitting the switching information of the transmission signal, and the switching information is received by the switching information receiving unit 15 after confirming the switching signal. Since only the switching information is received, the distinction between the switching information and the communication information becomes clear, and a communication switching system that does not require any restriction on the communication information can be realized.
