The network management module includes: a first connector electrically connected to the external processor; and a second connector electrically connected to the external processor A first communication module electrically connected to the first connector; and a second communication module electrically connected to the second connector and the first communication module; wherein, the first communication module The second communication module receives a first external signal through the second connector, and the second communication module provides a first signal to the first communication module according to the first external signal, so that the The first communication module is communicatively connected to an external server; Wherein, the second communication module receives a second external signal through the first connector, and the second communication module provides a second signal to the first communication module according to the second external signal , So that the first communication module interrupts the communication connection with the external server; wherein, the first external signal and the second external signal are external telephone signals; wherein, the second communication module passes through a The verification method verifies the first external signal and the second external signal, and the verification method is a phone number verification, a voice data repeat verification, a phone message verification, a ringtone Morse password verification, or a one-time password verify. For example, the network management module described in item 6 of the scope of patent application, wherein the second communication module is a wired communication module, a telephone communication module, a wireless fidelity communication module, and a Bluetooth communication module Group, a near field communication module, a LoRa communication module, an NB-IoT communication module or a Sigfox communication module, the first communication module is a wired communication module, a wireless fidelity communication module Group, Bluetooth communication module, one Zigbee communication module, one LoRa communication module, one Sigfox communication module, and one NB-IoT communication module. According to the network management module described in item 6 of the scope of patent application, the external processor is arranged in a gateway device. A network management method is suitable for a network management device. The network management device includes a first communication module and the second communication module. The network management device is set in a first area, and The network management method includes the following steps: providing at least one external signal to the second communication module; the second communication module verifies the at least one external signal through a verification method; the second communication module is based on The at least one external signal provides a control signal to the first communication module; and the first communication module establishes or interrupts a communication path according to the control signal; wherein the first communication module is electrically Connected to the second communication module; Wherein, the at least one external signal is an external telephone signal; wherein, the verification method is a phone number verification, a voice data repeat verification, a phone message verification, a ringing Morse password verification, or a one-time password verify. According to the network management method described in item 9 of the scope of patent application, the network management device further includes a processing module, and the first communication module and the second communication module are electrically connected to the processing module Group, the network management device is communicatively connected with a first electronic device and a first server, and the first server is a local server. The network management method according to claim 10, wherein, in the step of providing at least one external signal, the second communication module provides a first signal to the first external signal according to a first external signal. Communication module, so that the first communication module is connected to an external network or a second server. The second server is a remote server. When the first communication module is connected to the In the case of the external network or the second server, the first server communicates with the second server, and the second communication module provides a second signal to The first communication module, so that the first communication module interrupts the communication connection with the second server, the first server also interrupts the communication connection with the second server, the first The first signal is a communication connection signal, and the second signal is a communication interruption signal. The network management method described in item 11 of the scope of patent application, wherein the second communication module is a wired communication module, a telephone communication module, a wireless fidelity communication module, and a Bluetooth communication module , A near field communication module, a LoRa communication module, an NB-IoT communication module or a Sigfox communication module, the first communication module is a wired communication module, a wireless fidelity communication module , Bluetooth communication module, a Zigbee communication module, a LoRa communication module, a Sigfox communication module, and an NB-IoT communication module. The network management method described in item 9 of the scope of patent application, wherein the network The management device is a gateway device.
