1. A communication network switching apparatus, comprising a first communication network interface, a second communication network interface, a processor, a communication network switch, and a device access interface, wherein
the first communication network interface is connected to a first communication network, the second communication network interface is connected to a second communication network, and the first communication network interface and the second communication network interface are separately connected to the processor through the communication network switch;
the communication network switch is configured to switch, according to a control signal of the processor, a connection manner with the first communication network interface and the second communication network interface and connect the first communication network or the second communication network to the processor; and
the processor is connected to the device access interface and is configured to connect a target communication network connected through the communication network switch to a target device connected to the device access interface;
the apparatus further comprises a network isolator, wherein
a first end of the network isolator is connected to the device access interface; a second end of the network isolator is connected to the first communication network interface or the second communication network interface; and a connection end of the communication network switch and the first communication network interface is used as a first connection end, and a connection end of the communication network switch and the second communication network interface is used as a second connection end;
correspondingly, a third end of the network isolator is connected to the first connection end or the second connection end according to a communication network interface connected to the network isolator, and a fourth end of the network isolator is connected to the processor;
the network isolator is configured to, in a case where it is determined that the processor is connected to the first communication network or the second communication network, set a communicatively connected state between the first end of the network isolator and the fourth end of the network isolator and between the second end of the network isolator and the third end of the network isolator; and
the network isolator is further configured to, in a case where it is determined that the processor is not connected to a communication network, set the communicatively connected state between the first end of the network isolator and the second end of the network isolator.
