The network management system 1 of the present embodiment is provided in the first area a 1. The network management system 1 includes a network management device 11, a first server 12 and an electronic device group 13. In the present embodiment, the electronic device group 13 includes four electronic devices, namely a first electronic device 131, a second electronic device 132, a third electronic device 133 and a fourth electronic device 134.
The first server 12 is communicatively connected to a second server 2 via the network management device 11.

The processing module 110 is electrically connected to the first communication module 111, the second communication module 112, the power module 113 and the storage module 114. The first communication module 111 is electrically connected to the second communication module 112.
The first communication module 111 of the network management apparatus 11 is communicatively connected to the first server 12 and the external network ON. The first communication module 111 is communicatively connected to the second server 2 via an external network ON. The first electronic device 131, the second electronic device 132, the third electronic device 133 and the fourth electronic device 134 are respectively connected to the first server 12 through the network management device 11. In the present embodiment, the first server 12 is a local server (local server). In other embodiments, the network management system 1 may not include the first server 12, i.e. the first server 12 is merely a component that the network management system 1 may choose to include or not include. The network management system 1 can operate only by using the network management device 11 and the communicatively connected first electronic device 131, second electronic device 132, third electronic device 133, and fourth electronic device 134, without connecting to the first server 12 or the second server 2. The second server 2 is a remote server (remote server). The network management device 11 is a Gateway device (Gateway), that is, the network management system 1 in the first area a1 is not continuously connected to the external network ON or the second server 2. In this embodiment, the first server 12 of the network management system 1 can only perform communication connection with the external network ON or the second server 2 when the external network of the network management apparatus 11 is opened.

The first communication module 111 of the network management device 11 is a wired communication module, a wifi communication module, a bluetooth communication module, a zigbee communication module, a LoRa communication module, a Sigfox communication module, and an NB-IoT communication module. That is, the first communication module 111 may establish a first communication path CP1 with the second server 2.
The second communication module 112 of the network management apparatus 11 is a telephone communication module, and includes a wired telephone communication module (not shown) and a mobile communication module (not shown).

The second communication module 112 provides a first signal to the first communication module 111 according to a first external signal, so that the first communication module 111 is communicatively connected to the second server 2. When the first communication module 111 is communicatively connected to the external network ON and the second server 2, the first server 12 is communicatively connected to the external network ON and the second server 2. The first external signal is a communication connection signal.
In addition, the second communication module 112 provides a second signal to the first communication module 111 according to a second external signal, so that the first communication module 111 interrupts the communication connection with the external network ON and the second server 2, and the first server 12 also interrupts the communication connection with the external network ON and the second server 2. The second external signal is a communication interrupt signal.
The first external signal and the second external signal are respectively provided by a mobile communication device or a wired telephone device of a telephone number in a preset telephone table. The predetermined telephone list is stored in a storage module 114 of the network management device 11.

The internal signal may include a timing signal of the first electronic device 131, the second electronic device 132, the third electronic device 133 and the fourth electronic device 134, or a warning signal indicating that the first electronic device 131, the second electronic device 132, the third electronic device 133 and the fourth electronic device 134 detect that the first area a1 is abnormal. In addition, the internal signal may be added with a verification procedure according to actual requirements, and is not limited in the present invention.
In the present embodiment, the second communication module 112 is a telephone communication module having at least one fixed telephone number. And the predetermined telephone table includes a plurality of authenticated telephone numbers. When the mobile communication device or the wired telephone device dials into the second communication module 112, a communication connection message or a communication interruption message is provided to the second communication module 112 by voice. The processing module 110 first verifies whether the phone number of the dialed mobile communication device or wired phone device matches a plurality of authentication phone numbers in the predetermined phone list. If the phone number verification result is "yes", the processing module 110 will again determine whether the voice data providing the communication connection message is a verified voice signal. If the phone number verification result is "no", the processing module 110 will not process the request.
If the voice verification result of the communication signal is "yes", the processing module 110 requests the second communication module 112 to provide a first signal to the first communication module 111. An external communication address (IP address) is included in the first signal. If the voice verification result of the communication signal is "no", the processing module 110 will not process the request. In other embodiments, the processing module 110 may require the user to input a predetermined password or a verification request, which may be designed and adjusted according to actual requirements, but is not limited in the present invention.
In this embodiment, when the first communication module 111 obtains the external communication address, a communication path may be established with the external network, however, in order to ensure information security, the network node to which the first communication module 111 is communicatively connected needs to be limited. That is, the first communication module 111 can only be communicatively coupled to network nodes on a secure communication list. The secure communication list comprises at least one secure communication address. That is, when the first communication module 111 is forced to communicatively connect other communication addresses, the processing module 110 may forcibly turn off the first communication module 111. That is, the processing module 110 compares the communication address of the network node to which the first communication module 111 is connected for external communication, and when the processing module 110 finds that the communication address of the network node to which the first communication module 111 is communicatively linked is not in the secure communication list, the processing module 110 sends a communication interruption signal to the first communication module to interrupt the communication connection of the first communication module 111. In other embodiments, the processing module 110 may also send a power-off signal to the power module 113 to turn off the power of the first communication module 111. The list of secure communications is stored in the storage module 114.
Further, the processing module 110 may control the first communication module 111 to be turned on or off according to the first external signal and the second external signal. That is, the processing module 110 may turn on or off the power supplied from the power module 113 to the first communication module 112 according to the first external signal and the second external signal.
In other embodiments, the processing module 110 may only turn on or off the second communication path between the first communication module 111 and the second server 2.
That is, when the first communication module 111 does not receive the communication connection signal or the communication interruption signal provided by the second communication module 112, the first communication module 111 is in a standby state or a power-off state.
In this embodiment, the power module 113 is a dc-dc conversion module, an ac-dc conversion module or a battery module, which is not limited in the present invention.

[ third embodiment ]
Referring to fig. 1, fig. 2 and fig. 4, fig. 4 is a flowchart of a network management method according to a third embodiment of the present invention.
In this embodiment, the present invention provides a network management method, which is suitable for the network management system and the network management device 11 of the previous embodiment, and the structures and functions of the network management system and the network management device 11 are not described in detail in this embodiment. The network management method of the embodiment comprises the following steps:
providing at least one external signal to the second communication module (step S110);
verifying at least one external signal (step S120);
providing a control signal to the first communication module (step S130); and
a communication path is established or interrupted according to the control signal (step S140).
In step S110, the network management apparatus 11 includes a processing module 110, a first communication module 111, a second communication module 112, a power module 113 and a storage module 114. The processing module 110 is electrically connected to the first communication module 111, the second communication module 112, the power module 113 and the storage module 114. The first communication module 111 is electrically connected to the second communication module 112. The first communication module 111 of the network management apparatus 11 is communicatively connected to the first server 12 and an external network ON. The first communication module 111 is further in communication connection with the second server 2 through the external network ON. The first electronic device 131, the second electronic device 132, the third electronic device 133 and the fourth electronic device 134 are respectively connected to the first server 12 through a network management device. In the present embodiment, the first server 12 is a local server (local server). The second server 2 is a remote server (remote server). In other embodiments, the network management system 1 may not include the first server 12, i.e. the first server 12 is merely a component that the network management system 1 may choose to include or not include. The network management system 1 can operate only by using the network management device 11 and the communicatively connected first electronic device 131, second electronic device 132, third electronic device 133, and fourth electronic device 134, without connecting to the first server 12 or the second server 2. The network management device 11 is a Gateway device (Gateway), that is, the network management system 1 in the first area a1 is not continuously in communication with the second server 2. In this embodiment, the first server 12 of the network management system 1 can only perform communication connection with the second server 2 when the external network of the network management apparatus 11 is opened. The first communication module 111 of the network management device 11 is a wired communication module, a wifi communication module, a bluetooth communication module, a zigbee communication module, a LoRa communication module, a Sigfox communication module, and an NB-IoT communication module. That is, the first communication module 111 may establish a first communication path CP1 with the second server 2.
The first electronic device 131, the second electronic device 132, the third electronic device 133, and the fourth electronic device 134 include: a network image capture device, a personal computer, a tablet computer, a mobile phone, a notebook computer, an intelligent networked home appliance, a gateway device, a storage device, a network storage device or a local server.
In steps S120, S130 and S140, the second communication module 112 of the network management apparatus 11 is a telephone communication module, and includes a wired telephone communication module (not shown) and a mobile communication module (not shown). That is, the user can establish a second communication path CP2 with the second communication module 112 through the telephone. In other embodiments, the second communication module may also be a phone communication module, a wireless fidelity communication module, a bluetooth communication module, a nfc module, a LoRa communication module, an NB-IoT communication module, or a Sigfox communication module, which is not limited in the present invention. The second communication module 112 provides a first signal to the first communication module 111 according to a first external signal, so that the first communication module 111 is communicatively connected to the second server 2. When the first communication module 111 is communicatively connected to the second server 2, the first server 12 is communicatively connected to the second server 2. The first external signal is a communication connection signal.
In addition, the second communication module 112 provides a second signal to the first communication module 111 according to a second external signal, so that the first communication module 111 interrupts the communication connection with the second server 2, and the first server 12 also interrupts the communication connection with the second server 2. The second external signal is a communication interrupt signal. The first external signal and the second external signal are respectively provided by a mobile communication device or a wired telephone device of a telephone number in a preset telephone table. The predetermined telephone list is stored in a storage module 114 of the network management device 11.
In the present embodiment, the second communication module 112 is a telephone communication module having at least one fixed telephone number. And the predetermined telephone table includes a plurality of authenticated telephone numbers. When the mobile communication device or the wired telephone device dials into the second communication module 112, a communication connection message or a communication interruption message is provided to the second communication module 112 by voice. The processing module 110 first verifies whether the phone number of the dialed mobile communication device or wired phone device matches a plurality of authentication phone numbers in the predetermined phone list. If the phone number verification result is "yes", the processing module 110 will again determine whether the voice data providing the communication connection message is a verified voice signal. If the phone number verification result is "no", the processing module 110 will not process the request. In other embodiments, the method for verifying the communication connection message may further include: voice data recall verification, phone short message verification, ring tone moss password verification, or One-time password (OTP). The voice data repeating verification requires the user to repeat a sentence to compare with the data in the voice database stored in the storage module 114, and if the voice characteristics are the same, the verification is passed. The phone short message is to directly send a verification short message (including a short message for verifying the website or requiring the user to return a data) to the phone number stored in the storage module 114 to confirm whether the user is himself or herself. The ring Morse password authentication is that when the user makes a call to the second communication module 112, the number of times the ring sounds can be used for authentication. The one-time password is notified to the user by short message, and the user is requested to input or return the one-time password provided by the system for verification.
If the voice verification result of the communication signal is "yes", the processing module 110 requests the second communication module 112 to provide a first signal to the first communication module 111. An external communication address (IP address) is included in the first signal. If the voice verification result of the communication signal is "no", the processing module 110 will not process the request. In other embodiments, the processing module 110 may require the user to input a predetermined password or a verification request, which may be designed and adjusted according to actual requirements, but is not limited in the present invention.
In this embodiment, when the first communication module 111 obtains the external communication address, a communication path may be established with the external network, however, in order to ensure information security, the network node to which the first communication module 111 is communicatively connected needs to be limited. That is, the first communication module 111 can only be communicatively coupled to network nodes on a secure communication list. The secure communication list comprises at least one secure communication address. That is, when the first communication module 111 is forced to communicatively connect other communication addresses, the processing module 110 may forcibly turn off the first communication module 111. That is, the processing module 110 compares the communication address of the network node to which the first communication module 111 is connected for external communication, and when the processing module 110 finds that the communication address of the network node to which the first communication module 111 is communicatively linked is not in the secure communication list, the processing module 110 sends a communication interruption signal to the first communication module to interrupt the communication connection of the first communication module 111. In other embodiments, the processing module 110 may also send a power-off signal to the power module 113 to turn off the power of the first communication module 111. The list of secure communications is stored in the storage module 114.
