Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
As shown in fig. 1, an internet of things communication method applied among a plurality of lora gateways according to an embodiment of the present invention includes:
and S11, receiving an Internet of things communication request from the Internet of things request device, wherein the Internet of things communication request comprises the requested target device ID.
Regarding the execution subject of the method of the embodiment of the present invention, it may be one of the lora gateways under the plurality of lora gateways of the internet of things. It is understood that each lora gateway will have connected to it and manage some internet of things devices (e.g., light fixtures, air conditioners, curtain controllers, etc.) below it. Correspondingly, the internet of things request device in the embodiment of the present invention may be an internet of things device that requests to access a network or requests to perform data subscription or data publishing.
And S12, judging whether a target device access parameter corresponding to the target device ID exists in the device information list, wherein the device information list stores device access parameters of the Internet of things devices managed under different lora gateways.
It should be noted that the device information list storing the device access parameters of the devices of the internet of things under different lora gateways may be manually configured on one hand, and may also be automatically generated or updated (to be developed below) in the communication process of the internet of things on the other hand, and all of them are within the protection scope of the present invention. In addition, the device access parameter may represent some configuration parameter required for accessing the internet of things device for pairing, for example, it may be a device address and/or a key representing the internet of things device, and so on.
And S13, if the target Internet of things access parameter exists, carrying out data communication with the target Internet of things equipment corresponding to the target equipment access parameter.
In the embodiment of the invention, the device information list is inquired through the lora gateway according to the ID of the target device, so that the access parameter of the target device of the target Internet of things device is determined.
As a further disclosure and optimization, a local area network is built among a plurality of lora gateways, and a device information list is shared in the local area network. Therefore, all the internet of things equipment in the internet of things can be managed based on the equipment information list configured in one lora gateway, and communication operation configuration of the internet of things is facilitated.
In some embodiments, there is only a single platform lora gateway for interactive communication with the internet-of-things server among the plurality of lora gateways, wherein all the lora gateways except the platform lora gateway among the plurality of lora gateways are in communication interaction with the internet-of-things server through the platform lora gateway via the local area network. Specifically, a plurality of lora gateways may form a local area network based on mqtt bridging. It should be noted that the platform lora gateway may be the lora gateway for executing the method according to the embodiment of the present invention, and it may also be the lora gateway that is not executing the method according to the embodiment of the present invention, and all of them are within the scope of the present invention. Therefore, when some application scenes needing platform participation of the Internet of things are realized, sharing among all the lora gateways in the local area network can be realized only by allowing one platform lora gateway and communication interaction platform information in the local area network, and the gateway configuration cost is reduced on the premise of ensuring the richness of the application functions of the Internet of things.
Further, when the internet of things equipment requests for internet of things communication operation, the situation that the target equipment access parameter corresponding to the target equipment ID does not exist in the equipment information list on the lora gateway exists, and the target equipment ID is required to be obtained through communication and interaction with the internet of things server at the moment, so that the reliability of communication is guaranteed. Specifically, when it is judged that the target device access parameter corresponding to the target device ID does not exist in the device information list, the internet of things communication request is sent to the platform lora gateway, so that the platform lora gateway forwards the internet of things communication request to the internet of things server, and then the target device access parameter responding to the internet of things communication request is received from the platform lora gateway, so that response pairing of the internet of things communication request is completed; also, the device information list may be updated based on the target device access parameter and the target device ID. Therefore, the updated device information list enables the device information list to be called directly from the device information list when the same internet of things communication request is received again next time without data interaction with the platform server, and the method can also be directly used for creating the device information list, for example, the device information list which is just started does not have data, and is gradually updated and created later.
In the embodiment of the invention, considering that in the local area network, the requirement of a client on a management platform is not high, aiming at the problem of the local area network, the virtual management platform in the local area network is realized through the cooperative work between the gateway and the gateway. Through the cooperative work of the gateway and the gateway in the local area network, the device can generate corresponding information such as a secret key and an address in the gateway. Thus, the lora gateway can manage the device information by itself without deploying a device management platform. The cost is saved, the deployment is convenient, and special software and hardware conditions are not needed. The small-scale platform management can be realized within the range of the local area network, and the direct deployment of users is facilitated.
Specifically, in the embodiment of the invention, an internet of things universal technology mqtt protocol is used. And the interaction between the gateways is realized by using a bridging technology in the mqtt protocol. The communication of the gateways between the local area networks can be realized through the bridging between the gateways, so that the messages of the equipment can be communicated at each gateway. A main application is created in the local area network to realize the management of the equipment, so that the equipment under a plurality of gateways in the local area network can be managed.
The lora gateway provided by the embodiment of the invention has the following advantages:
1) the intercommunication between the gateways realizes the intercommunication between the gateways in the local area network through the mqtt bridging technology, and then the unified management of the equipment under a plurality of gateways can be realized. For example A, B two gateways (as shown in fig. 2), the virtual platform application of one gateway is turned on, and the other gateway turns off the application (by default, only one device management application is turned on in a lan, the management platform in the B gateway is not turned on, and the management platform in the a gateway is turned on). It can be seen that AB is bridged together by mqtt technology, at this time, the applications of the a gateway and the B gateway subscribe to the same topic, when there is a device reporting or a request for data in the a gateway, data processing is published on the application of mqtt by lora application, and the B gateway can subscribe to the lora application in the a gateway to publish messages.
2) The device management can realize that the application can receive the device from any gateway through the communication between the gateways, so that the device information can be matched from the application and some network access information of the device can be generated. The client does not need a server to deploy a corresponding equipment management platform, and only simple interaction between the gateway and the platform is needed, so that the cost of the client is greatly reduced, and the deployment is facilitated.
3) And the local area network is communicated with the gateway. Forming a small local area network between the gateways. Scene applications in small items can be realized in the case of forming a local area network.
In some lora application scenes, a client can manage the equipment only by using an equipment management platform, and the management mode has certain risks, the platform must be deployed, and the problem of the platform is not favorable for normal use. By changing the existing situation in this way, the stored device list is realized according to the gateway application, so that the device list can be used by a customer through direct purchase without deploying a corresponding platform management system.
The embodiment of the invention mainly relates to the aspects of the cooperative work of a gateway internal structure and multiple gateways, wherein Lora application, virtual platform application and Mqttbus application are configured on the gateway internal structure, and platform information is interacted between one platform gateway and a server and shared in a local area network in the cooperative work of the multiple gateways.
1) Gateway internal structure
In order to realize a virtual management platform, the Lora gateway divides the gateway into Lora application, virtual platform application and mqttbus application. Different units implement different functions, and different applications implement management through mqttbus before. And the intercommunication and division of work among all units are realized.
The Lora application mainly realizes the transparent transmission of the data reported by the equipment to the virtual platform application. The data from the equipment is converted into a json format through the application, and the virtual platform application receives the data by subscribing corresponding subjects on the application of the data pub to the mqttbus.
The virtual platform application mainly realizes the function of equipment management, namely the equipment management application manages and generates the information reported by the equipment through the lora application. The device information of the application platform is transmitted on the mqttbus application, and each gateway can receive the data from the application. This allows communication to be applied between the gateways.
Mqttbus applications are implemented through bridging techniques in the mqtt protocol. The communication between each gateway can be realized by configuring corresponding parameters, and the basis of the communication between the virtual application platform and each gateway is realized. By subscribing and publishing the same theme, the intercommunication between gateways in the local area network can be realized.
2) Procedure for collaboration between gateways
First, device list information is generated in the gateway or device information is imported. If there are 3 gateways a, B, and C, only the virtual platform application of the gateway a is open, and the virtual platform applications of the other two gateways are not open (only one gateway opens the management platform application in the lan).
As shown in fig. 3, an exemplary architecture of a multi-lora gateway internet of things communication to which the embodiments of the present invention are applied. Three important constituent units of A, B and C are extracted to form a structure shown in figure 3, a plurality of devices are connected below each gateway, each device receives data through lora application, the data are reported to the mqttbus application through an mqtt protocol after the data are received, the data are sorted through the application, and if the data are useless, the data received by the gateway can be lost.
When the equipment is powered on, the information of the equipment is reported, a lora application program in a gateway B receives data, and when the equipment in the lora application program is searched, if the equipment information exists, the equipment information is reported to a server. If the device information is not received, an instruction for inquiring the device information is issued to the mqtt bus to search the device information. Because all gateways are intercommunicated, the gateway A can receive the equipment information from the gateways B and C, and the virtual platform application in the gateways B and C is not started, so the data is not processed.
And after the A gateway subscribes to the equipment information, processing the requested information. And searching a device information list, and if matched device information exists, issuing some parameter information of the device information to the mqtt application. Therefore, the gateway B can receive the corresponding equipment information and can decrypt and analyze the data according to the equipment information.
When processing data, each gateway processes the data according to different data formats. Only one virtual platform application exists in a local area network, so that the phenomenon that device information is wrong in management can be prevented, the reported device information of data is stored in the lora application, the access to the virtual application platform is reduced, when the information of the device cannot be found in a memory space distributed by the lora application, a message of a device information request is initiated, the access of the data to the mqttbus application is reduced, and unnecessary messages are reduced.
3) Virtual platform logic
The communication between the gateways is enabled through the bridging among the gateways. Therefore, when the device reports data, the gateway does not need to be bound, and the virtual platform application realizes the function of original device platform management.
For example, a device reports a join request when joining a gateway, and after receiving information reported by the device, a lora application in the gateway processes the message, searches whether the device has device information in the lora application according to the reported address, and if the device has the device information, the device does not need to be issued to an mqttbus application. If the device does not exist, the id of the upper device is reported to the mqttbus application, the corresponding device request information is subscribed through the virtual platform, and the device information is traversed through the device list of the device.
And finding equipment information according to the traversal result, and applying the mqtt published with some parameters of the equipment information, so that the lora application can subscribe the equipment information from the application of the mqttbus, and the parameters required by the equipment are sent to the equipment, and the equipment can access the network according to the information.
When the device reports data later, the lora application stores some parameter information of the device, so that the device does not need to access the virtual platform every time the device reports one data, and unnecessary data is reduced. When the device registers successfully on the gateway a, the gateway a stores the device information, but when the device reports information to the gateway B (roaming state), the gateway B does not have the parameter information of the device. At this time, the lora application in the B gateway issues the device information to the mqttbus application.
After the parameters of the equipment are traversed by the virtual platform application and the equipment information is found, the lora application compares the equipment information and decrypts the equipment data after receiving the equipment information through the steps.
