Abstract A method for implementing the redundancy of bus-type computer network is disclosed. A special module, which is composed of two network interfaces, a program controller with firmed executive sequence and an alarm-record device, is serially connected to the serial bus of bus-type computer network. The network and the alarm-record device are respectively connected with program controller. Two network interfaces are respectively connected to both ends of serial bus to avoid "common failures caused by same cause" without modification to existing software and hardware. Its advantages are high network security and low cost.
