When the master node device and other node devices in each device group are not managed by the controller, that is, the master node device and other node devices are not in management connection with the controller, a broadcast message is periodically sent in the two-layer network, and the broadcast message includes the identification information of the node device, the current IP address information of the node device, and the like.
In step S101 of the present invention, the master node device sends a broadcast packet so that the address notifier finds a master node device that is not managed by the controller and issues controller address information to the master node device; in another application, the master node device may send the broadcast packet to the periphery, and the controller in the two-layer network may directly discover the master node device, so as to directly manage the node device in the two-layer network. Step S103 specifically includes: after the main node equipment receives the response of the address notifier, the main node equipment establishes safe connection with the address notifier, analyzes the received controller address information to obtain the target IP address of the controller, and initiates a unicast management request message to the target IP address of the controller. And after receiving the management request message through the Internet, the controller at the far end establishes management connection with the main node equipment corresponding to the management request message and controls the main node equipment to execute a corresponding control command through the management connection. In step S104, the master node device that has established management connection with the controller starts a detection function, detects the peripheral node devices to be networked, and reports a detection result, for example, information of the node devices to be networked, to the controller.

After the wireless networking connection of the node device to be networked is successful in step S106, analyzing the received ciphertext according to the key to obtain the controller address information, and analyzing the controller address information to obtain the IP address information of the controller; and initiating a unicast management request to the controller according to the IP address information of the controller. And when the node equipment to be networked establishes management connection with the controller, namely is managed by the controller, completing one operation of remotely adding the wireless equipment node.

if not, the controller issues a kicking-out command to the upper connection node equipment connected with the node equipment to be networked in a networking mode, so that the upper connection node equipment kicks the node equipment to be networked out of the networking mode.
It should be noted that, in the embodiment of the present invention, the controller is responsible for monitoring the management request of the wireless node devices in each device group, and after monitoring, establishing a management connection with the corresponding wireless node device, and then executing a corresponding wireless networking decision according to the node device information to be networked, which is detected by the wireless node devices in each device group, and issuing a corresponding wireless networking command to the corresponding node device. In the wireless networking, in order to prevent the situation that the uncontrolled wireless node equipment accesses the network and occupies network resources when the networking node equipment which is being processed has accessed the network but the controller does not receive the managed request initiated by the node equipment, the controller monitors whether the added wireless node equipment has established management connection within the preset effective time after issuing the networking allowing command; the method comprises the steps that the networking node equipment is reported with equipment information by the networking node equipment in the process of waiting for networking, and after the added node equipment is connected to a network through a wireless networking, a management request message is sent to a controller end, the management request message contains equipment identification information of the node equipment, and when the controller receives the management request message of any node equipment, the controller correspondingly identifies the networking management of the node equipment. And after the node equipment to be networked is networked and a unicast management request is sent to the controller according to the address information of the controller so as to establish management connection with the controller, when the controller detects that the equipment information of any node equipment to be networked does not identify networking management, namely the management connection is not established with the controller, the access of the wireless node equipment is not allowed. And the controller issues a kick-out command to the upper-connection node equipment connected with the node equipment to be networked in a networking manner, so that the upper-connection node equipment executes the processing of kicking out the node equipment to be networked after receiving the kick-out command.

It should be noted that, after the networking node device establishes a management connection with the controller, the mechanism for detecting other wireless node devices around is also started, and a detection result, for example, the information of the node device to be networked, is reported to the controller. The controller feeds back the received node equipment information of the node equipment to be networked to a user, and when the user issues a decision result of allowing networking, the controller issues a networking allowing command and the node equipment information of the node equipment to be networked to the node equipment which is in management connection with the controller according to the decision result, so that the user can manage the wireless networking of the node equipment through the controller.
Fig. 3 is a schematic diagram of node device networking according to a method for managing device group wireless networking according to an embodiment of the present invention.
After receiving a command allowing networking, the node equipment which has been networked and establishes management connection acquires a wireless management message Prboe Request of the node equipment to be networked; the wireless management message comprises a secret key and identity information; the node equipment verifies the identity information of the node equipment to be networked according to the received node equipment information to be networked; when the identity verification of the node equipment to be networked passes, the node equipment encrypts the controller address information acquired by the node equipment according to the key to generate a ciphertext, and carries the controller address information in a form of the ciphertext in a Response wireless management message Prboe Response to issue to the node equipment to be networked; when the identity verification of the node equipment to be networked passes, simultaneously opening a networking interface so that the node equipment to be networked is connected with the node equipment in a networking manner through the networking interface, wherein the node equipment is the uplink node equipment connected with the node equipment to be networked in a networking manner. After the node equipment to be networked is successfully connected with the wireless network, analyzing the received ciphertext according to the secret key to obtain the address information of the controller, and analyzing the address information of the controller to obtain the IP address information of the controller; and initiating a unicast management request to the controller according to the IP address information of the controller to complete the wireless networking of the node equipment. Node devices that implement the already-networked and established management connections are controlled by the controller to allow the addition of new downstream wireless node devices, thereby gradually expanding the entire wireless networking system.
Further, before the networking node device opens a networking interface and issues the controller address information to the node device to be networked, the method further includes:
the networked node equipment acquires a wireless management message of the node equipment to be networked according to the received networking allowing command; the wireless management message comprises a secret key and identity information;
the networked node equipment verifies the identity information of the node equipment to be networked according to the received node equipment information to be networked;
and when the verification is passed, the networked node equipment encrypts the controller address information according to the key to generate a ciphertext.
It should be noted that the source of the controller address information of all the wireless node devices in each device group is an address notifier. The controller address information of the master node device connected to the address notifier via the wired network in each device group is set by the address notifier. The acquisition source of the controller address information of each node device connected through the wireless network is the uplink node device connected with the wireless network. And finishing the notification of the controller address information among the wireless networking devices in a mode of notifying the lower-level node devices by the upper-level node devices. The time when the node equipment performing wireless networking acquires the address information of the controller is a detection stage. Specifically, the node device to be networked sends a wireless management message Prboe Request when seeking, where the wireless management message Prboe Request carries a key and identity information of the node device to be networked. When the networking node equipment receives a networking allowing command issued by a controller, the networking node equipment verifies the identity information of the networking node equipment according to the received networking node equipment information after judging that the networking node equipment is the node equipment allowed to be connected. And after the identity verification of the node equipment to be networked is passed, the node equipment key which is already networked encrypts the controller address information which is acquired by the node equipment key to generate a ciphertext, and carries the controller address information in a form of the ciphertext in a Response of the wireless management message Prboe Response to send the controller address information to the node equipment to be networked.
Further, the specific implementation process of step S106 may be:
the node equipment to be networked is connected with the networked node equipment through the networking interface to carry out networking;
the node equipment to be networked analyzes the received ciphertext according to the secret key to obtain the address information of the controller;
and the node equipment to be networked initiates a unicast management request to the controller according to the controller address information.
It should be noted that the node device to be networked is connected with the networked node device through the networking interface to perform networking. After receiving the Response wireless management message Prboe Response, the node equipment to be networked extracts a ciphertext from the Response wireless management message Prboe Response, and analyzes the address information of the controller from the ciphertext according to a secret key in the wireless management message; and initiating a unicast management request to the controller according to the IP address information of the controller, and completing the wireless networking and establishing management of the node equipment.
Further, the specific implementation process of step S102 may be:
the address notifier carries out identity verification on the main node equipment according to the broadcast message; the broadcast message comprises identification information and an IP address of the main node equipment;
and when the verification is passed, the address notifier sends the controller address information to the main node equipment corresponding to the broadcast message.
It should be noted that the address notifier in each device group is configured to notify the node devices in the same device group of the controller address information. When the controller is deployed, the address notifier needs to be configured with correct controller address information. When the controller target IP address is changed, the controller address information configured in the address notifier needs to be updated. In order to realize network security, the validity of the device needs to be verified before the address notifier and the master node device in the device group perform controller address information configuration. The address notifier carries out identity verification on the main node equipment according to the broadcast message; the broadcast message comprises identification information and an IP address of the main node equipment, and the address notifier sends the controller address information to the main node equipment corresponding to the broadcast message only when the equipment identity identification is matched with the equipment identity identification prestored in the address notifier and the verification is passed.
Further, after step S103, the method further includes:
the master node equipment detects the management connection with the controller at regular time;
when the management connection is detected to be disconnected, the main node equipment resends the broadcast message to request the address notifier to respond, and initiates a unicast management request to the controller again according to the original controller address information.
It should be noted that, in the embodiment of the present invention, if the controller address changes, the controller address information in each device group needs to be reconfigured. When the wireless master node device with wired access detects that the management connection with the controller is disconnected, the master node device cannot judge whether the reason of the management connection disconnection with the controller is the disconnection or the address change of the controller, so that the master node device sends a broadcast message in a two-layer network again to request the response of the controller or an address notifier. Meanwhile, a unicast management request is still sent to the original controller IP address of the current main node equipment, and if the address of the controller is changed, the management request does not have any response. At this time, after receiving the broadcast message sent by the master node device, the address notifier responds to the master node device with a new controller address, i.e., re-executes step S102 in the method. After receiving the new controller address information, the master node device parses out the IP address of the controller and then sends a unicast management request to the new controller address, so that the master node device establishes a management connection with the controller at the new location, that is, step S103 in the method is executed again.
Further, before step S103, the method further includes:
when the master node equipment receives the controller address information, the master node equipment detects whether a downlink node equipment connected with the master node equipment in a networking mode exists or not;
and if so, the main node equipment kicks all the lower connection node equipment out of the networking.
It should be noted that, in the embodiment of the present invention, if the controller address changes, the controller address information of the node devices in each device group needs to be reconfigured. When the address of the controller is changed and the master node equipment receives new controller address information sent by an address notifier, the master node equipment detects whether a downlink node equipment connected with the master node equipment in a networking mode exists or not; and if the network connection exists, the main node equipment kicks all the lower connection node equipment out of the network connection. When the node equipment of the network to be networked of the downlink connection is searched again, the main node equipment sends new controller address information to the node equipment of the network to be networked of the downlink connection through responding to the wireless management message. After receiving the new controller address, the node device of the network to be networked by the downlink initiates a management request to the new controller address. And meanwhile, the controller address information of the subsequent node equipment to be networked in the downstream is updated in a similar mode. And updating the controller address of the wireless node equipment in the whole equipment group finally after the gradual updating from the root node equipment to the leaf node equipment is realized.
Further, before step S102, the method further includes:
and when the controller address information is changed, the address notifier updates the locally stored controller address information. It should be noted that, after the controller target IP address is changed, the controller address information configured in the address notifier needs to be updated, so that the address notifier can notify the node devices in the device group of the correct controller address information.
