BUS NETWORK HAVING A SAFETY GATE OF A SUBSTANTIAL SAFETY ISOLATION TYPE

摘要

The present invention relate to a bus network having a safety gate of a substantial safety isolation type. The bus network comprises a first region, a second region, and signal isolators. The first region has disposed therein a first bus and has distributed therein one or more first processing devices, one or more first transceivers, one or more first controllers, and one or more gateways. The second region has disposed therein a second bus and has distributed therein one or more second processing devices and one or more second transceivers. The signal isolators are disposed between the first region and the second region. An isolation device driving terminal and an output terminal on one side of the signal isolator are respectively connected to a transmitting terminal and a receiving terminal of a second controller. An output terminal and an isolation device driving terminal on the other side of the signal isolator are respectively connected to a transmitting terminal and a receiving terminal of a second transceiver.
