Bus network having a safety gate of a substantial safety isolation type

A bus network having a safety gate of a substantial safety isolation type, comprising:

• a first region having disposed therein a first bus and having distributed therein one or more first processing devices, one or more first transceivers, one or more first controllers, one or more gateways, and one or more second controllers, wherein a signal terminal of the first processing device is connected to the first bus, the first bus is connected to a signal terminal of the first transceiver, a transmitting terminal and a receiving terminal of a respective first transceiver are respectively connected to a transmitting terminal and a receiving terminal of a respective first controller, control signal terminals of a respective first controller are respectively connected to respective control signal terminals of a respective gateway, respective control signal terminals of a respective gateway are respectively connected to respective control signal terminals of a respective second controller;
• a second region having disposed therein a second bus and having distributed therein one or more second processing devices and one or more second transceivers, wherein a signal terminal of a respective second transceiver is connected to the second bus, a signal terminal of a respective second processing device is connected to the second bus;
• a plurality of signal isolators disposed between the first region and the second region, wherein an isolation device driving terminal and an output terminal on one side of a respective signal isolator are respectively connected to a transmitting terminal and a receiving terminal of a respective 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 respective second transceiver.
