一般注記This paper describes a new optical coupling device for an airborne digital redundant system. For an on-board system, it is very important to increase reliability and safety, so a redundant system is applied. In a redundant system, in order to verify whether each operation is correct, it is necessary to compare it with the same time data from other systems. We developed a new characteristic coupling device and verified its features experimentally. This system has the following characteristics : 1.It has a simple hardware architecture in order to increase reliability and safety. 2.Synchronization and data exchange are separated in time, so this system utilizes the same hardware for these tasks. 3.To increase transfer speed, a broadcast method is used and the number of receivers is (redundancy-1); thus each system can transmit and receive simultaneously. 4.An optical signal is used in order to increase transfer speed and this is effective for electric separation among systems. The paper ends with a discussion of how to recognize the end of transfer without an interrupt signal in a digital computer.
