Hereinafter, a network access method of a node device according to an exemplary embodiment of the present disclosure is explained and explained in detail with reference to the drawings.

First, terms referred to in the exemplary embodiments of the present disclosure are explained and explained.

Long Range Radio (Long Range Radio) is a low power consumption local area network wireless standard created by semtech corporation, and is a modulation technology of linear frequency modulation spread spectrum; the wireless communication system is characterized in that the distance of transmission is longer than that of other wireless modes under the same power consumption condition, and low power consumption and long distance unification are realized.

In practical application, the LoRa communication generally adopts a directional transmission mode, and the LoRa module needs to configure the following parameters:

channel (0-31): corresponding to the communication frequency, the LoRa module generally supports the communication frequency of 410-441 Mhz, and has 32 channels;

address (0-65535): different LoRa modules are distinguished through addresses and used for message addressing;

of course, the channel and address parameters must be unique for each device, otherwise collisions will result, resulting in communication failures; other parameters may also include multiple parameters such as power, baud rate, parity check mode, etc., but these parameters may be unified among different devices. In addition, the message initiator needs to know the address and channel of the receiver to send the message to the other party, and a specific application scenario diagram can be referred to as fig. 2.

Next, the object and application scenarios of the exemplary embodiments of the present disclosure will be explained and explained.

For the existing scheme, before one node device works normally, the following two configurations need to be completed manually: in one aspect, the LoRa module is configured. Specifically, the address and the channel of the LoRa module used by the node device need to be configured, and these two parameters must be unique in the application scenario to ensure that no communication conflict occurs; moreover, the configuration of the LoRa module may be configured individually through an interface provided by the LoRa module (generally, AT instruction setting is sent through a serial port), or may be configured by the node device during the operation process (the configuration of the node device needs to be modified, and the configuration information of the LoRa module is written in);

and on the other hand, configuring the gateway address. Specifically, the LoRa address and the channel of the gateway device need to be set in the node device (the configuration of the node device needs to be modified), and the node device can designate the receiver of the message when calling the LoRa module interface to send the message.

For an application scenario with only a single gateway, the configuration of the gateway LoRa may be fixed, in which case fixed gateway LoRa configuration information may be written in the node device program; however, for some complex application scenarios, the node devices are numerous, and when multiple gateways are needed (different channels are used for networking respectively), the accessed gateway information must be set in the node devices. Therefore, to configure a new node device, it is necessary to modify the configuration of the LoRa module and the node device, and it is very troublesome to recompile the program or use a dedicated external interface, which increases the cost of operation and maintenance.

Therefore, the disclosed example embodiment provides a new network access method for node devices, and the dual-LoRa channel is configured in the gateway device to implement self-configuration of the LoRa module of the node device, so that the node device is directly used without configuration in operation and maintenance. Simultaneously, when using loRa networking scheme in using to current thing networking, the node equipment loRa module configuration that meets in the fortune dimension is loaded down with trivial details, replace complicated scheduling problem during node equipment trouble, through the gateway equipment that has the dual channel, a channel is exclusively used in node equipment's self configuration, a channel is exclusively used in actual acquisition data transmission, and increase control switch, open in a flexible way and stop the self configuration function, thereby realize that the loRa module exempts from to configure direct use in the fortune dimension in-process, reduce fortune dimension work load, reduce fortune dimension complexity, extra consumption has also been reduced.

Further, a network access system of a node device according to an exemplary embodiment of the present disclosure is explained and illustrated. Referring to fig. 3, the network entry system of the node device may include a node device 310, a gateway 320, a web server 330, and an application server 340. The node equipment, the gateway, the network server and the application server are sequentially in communication connection.

Specifically, the node device is used for sending a network access request to the gateway, and the network server is used for receiving a network required by the network access of the node device sent by the gateway and sending the network to the corresponding application server, so as to realize the network access of the node device; the gateway may be configured to implement the network access method of the node device described in the exemplary embodiment of the present disclosure; the gateway may include a first LoRa module 321 and a second LoRa module 322; the first LoRa module may be configured to complete registration of the newly added node device, and the first LoRa module may be configured to complete network access of the historical node device.

Hereinafter, each step included in the network access method of the node device according to the exemplary embodiment of the present disclosure is explained and explained in detail with reference to fig. 3.

In a network access method of a node device according to an exemplary embodiment of the present disclosure:

in step S110, receiving a network access request sent by a node device, and authenticating the node device according to message information carried in the network access request to obtain a device type of the node device; wherein the device type comprises a newly added device or a historical device.

In this exemplary embodiment, first, a network access request sent by a node device is received; the node device may include various internet of things devices, such as a refrigerator, a television, a washing machine, and the like; secondly, after receiving the network access request, the node device may be authenticated according to the message information carried by the network access request, so as to obtain the device type of the node device. Specifically, as shown in fig. 4, the method may include the following steps:

step S410, decoding the message information carried by the network access request to extract a second device address and a second device channel of the node device, and a current gateway channel and a current gateway address of the gateway from the message information;

step S420, judging whether the current gateway channel and the current gateway address are consistent with a registered gateway channel and a registered gateway address of a first LoRa module;

step S430, if yes, matching the extracted second device address and the second device channel with a preset routing information table, and determining whether the node device is a newly added node device or a historical node device according to a matching result.

Specifically, matching the extracted address of the second device and the channel of the second device with a preset routing information table, and determining whether the node device is a newly added node device or a historical node device according to a matching result, which may specifically include: firstly, matching the second equipment address and the second equipment channel in the preset routing information table to obtain a matching result; secondly, if the matching result is that the second equipment address and the second equipment channel are both in the preset routing information table, the node equipment is historical node equipment; and finally, if the matching result is that the address of the second device and the channel of the second device do not exist in the preset routing information table, the node device is a newly added node device.

Further, referring to fig. 5, if the current gateway channel and the current gateway address are not consistent with the registered gateway channel and the registered gateway address of the first LoRa module, the network access method of the node device may further include the following steps:

step S510, if not, determining whether the current gateway channel and the current gateway address exist in the preset routing information table;

step S520, if yes, matching the second equipment address and the second equipment channel in the preset routing information table to obtain a matching result;

step S530, if the matching result indicates that the second device address and the second device channel both exist in the preset routing information table, the node device is a history node device;

step S540, if the matching result indicates that neither the second device address nor the second device channel exists in the preset routing information table, the node device is an illegal device.

The steps involved in fig. 4 and 5 will be explained and explained below.

First, a preset routing information table needs to be established. Specifically, the method for establishing the preset routing information table may include: firstly, recording identification information of each node device of a network user; the identification information of each node device comprises a manufacturer, a model number, a serial number, a user ID of a network and the like of each node device, and has uniqueness; secondly, the identification information of each node device is stored in association with a gateway channel and a gateway address; and finally, establishing a preset routing information table based on the identification information of the node equipment, the gateway channel and the gateway address.

That is, the route information table is established by pre-recording the identification information of each node device of the user, wherein the identification information of each node device of the user can be input by the user; after recording the identification information of each node device of a user, performing associated storage on the identification information of each node device, a gateway channel and a gateway address for associated storage, wherein the gateway channel and the gateway address have uniqueness; and finally, performing associated storage based on the gateway channel and the gateway address of the associated storage, namely establishing a routing information table.

Further, after the routing information table is obtained, the device type of the node device can be judged. Specifically, when a node device needs to access a network, the node device may send a network access request to a gateway, where the network access request carries message information, where the message information includes a device address, a device channel, a gateway address, and a gateway channel. It should be noted that, in order to prevent the message information from being maliciously tampered, the message information is pre-encapsulated into a frame structure agreed with the gateway, for example, the message information may be encapsulated in an internet protocol security IPSec manner, and the frame structure may be a self-defined frame structure or the like.

Therefore, after receiving a network access request sent by the node device, the gateway decodes the message information carried in the network access request according to a preset decoding mode corresponding to the encapsulation mode, so as to extract the second device address and the second device channel of the node device, the current gateway channel of the gateway and the current gateway address from the message information. Then, judging whether the current gateway channel and the current gateway address are consistent with the registered gateway channel and the registered gateway address of the first LoRa module; and if so, matching the extracted second equipment address and the second equipment channel with a preset routing information table, and determining whether the node equipment is newly added node equipment or historical node equipment according to the matching result.

Further, if the current gateway channel and the current gateway address are not consistent, judging whether the current gateway channel and the current gateway address exist in a preset routing information table or not; if the address exists, matching the second equipment address and the second equipment channel in a preset routing information table to obtain a matching result; if the matching result is that the second equipment address and the second equipment channel both exist in the preset routing information table, the node equipment is history node equipment; if the matching result is that the second equipment address and the second equipment channel do not exist in the preset routing information table, the node equipment is illegal equipment; when the node equipment is determined to be illegal equipment, alarm information can be generated and sent to a mobile terminal where a user is located, and therefore the user can timely process the illegal equipment. By the method, the safety of the network can be further improved.

In step S120, if the node device is a newly added device, a first LoRa module included in the LoRa gateway is called to allocate a first device address and a first device channel for the new addition, so as to complete registration of the newly added device.

In this example embodiment, when it is determined that the node device is a newly added device, a first LoRa module included in the LoRa gateway may be called to allocate a first device address and a first device channel for the newly addition, so as to complete registration of the newly added device. Specifically, as shown in fig. 6, the method may include the following steps:

step S610, calling a first LoRa module included in the LoRa gateway, and allocating a first device address and a first device channel to the newly added node device according to the device identifier included in the network access request;

in this example embodiment, first, a first LoRa module included in the LoRa gateway is called, and a switch of the first LoRa module is controlled to be in an on state; secondly, a first LoRa module in an open state is used for allocating a first equipment address and a first equipment channel for the new addition according to the equipment identification included in the network access request; wherein the first device address and the first device channel are both globally unique.

Step S620, the first equipment address, the first equipment channel, the working gateway channel of the second LoRa module and the working gateway address are sent to the newly added node equipment, so that the newly added node equipment completes registration on the first LoRa module according to the first equipment address and the first equipment channel, and sends a network access request to the second LoRa module according to the working gateway channel and the working gateway address to complete network access.

Hereinafter, step S610 and step S620 will be explained and explained. Specifically, first, a first LoRa module included in the gateway is called, the first LoRa module is a registered LoRa, and is specially used for initial registration of the node device, a first device address and a first device channel are allocated for the node device, and the node device is notified of a working gateway channel and a working gateway address of the working LoRa of the gateway device; the channel and address for registering the LoRa are fixedly allocated in advance, so that the node device can register conveniently. Fig. 7 may be referred to specifically for a node device registration procedure.

In fig. 7, the initial channel and address are fixed for a new unregistered node device (so that identical node devices can be produced); after the system is started, the node equipment is automatically connected with the LoRa registration and initiates a registration request (S1); after receiving the registration request, the registration LoRa (first LoRa module) allocates a globally unique first device channel and first device address to the node device according to the node device identifier, and returns the working gateway channel and the working gateway address of the gateway device together (S2, registration response); the node device saves the first device address, the first device channel, the working gateway channel of the second LoRa module, and the working gateway address (re-registration is not needed after re-boot, the working LoRa network can be directly connected), and modifies the configuration of the LoRa module (S3); and finally, restarting the LoRa module, and enabling the working LoRa of the connection gateway equipment to start normal work (S4, networking work). It should be added here that, by setting a "reset" switch on a node device, when a certain node device needs to replace a home gateway, the existing configuration can be cleared, and gateway registration is performed again, so that device reuse is simpler.

Further, when the newly added node device completes registration, the switch of the first LoRa module may be controlled to be in a closed state. Through increasing a registration loRa switch on gateway equipment, close when need not registering new node equipment at ordinary times, just open when need registering new equipment, can reduce whole consumption, avoid the wasting of resources.

It should be further added here that, in the process of allocating the working gateway channel and the working gateway address to the newly added node device, the following principles need to be observed: and distributing the working gateway channel and the working gateway address for the newly added node equipment according to the number of the historical node equipment associated with the working gateway channel and the working gateway address. That is, if the number of the history node devices associated with a certain working gateway channel and a working gateway address is too large, other working gateway addresses and working gateway channels are reallocated to the newly added node device. By the method, under the application scene with a plurality of gateways, the gateway to which the node equipment is registered can be accurately controlled, and the network access efficiency of each node equipment is further improved.

In step S130, if the node device is a history device, a second LoRa module included in the LoRa gateway is called, and a network of the node device is established in the gateway, so as to complete network access of the node device.

Thus, the network access process of the whole node device is completed. In addition, according to the network access method of the node device, the number of the gateways is much smaller than that of the node device, and only the dual LoRa are configured on the gateway device, so that the influence on the overall cost is very small, but the operation and maintenance improvement is very large; moreover, the node equipment can be produced in a unified and standardized manner, great convenience is brought to production, stock and replacement after failure of the node equipment, and a user can simply and automatically replace the node equipment without the cooperation of professionals; furthermore, the gateway equipment can be modified by a small amount, so that the cost is increased little; furthermore, only simple gateway registration is needed before use, the original complex configuration work is reduced, the operation and maintenance workload is greatly reduced, the LoRa configuration parameters of the node equipment are distributed by the gateway equipment without manual setting, and the registration and the working network are separated through double LoRa configuration of the gateway equipment; and finally, a control switch is added on the registered gateway, so that the power consumption can be reduced, and the gateway to which the node equipment is registered is accurately controlled.
