The device perception layer 101 comprises a plurality of internet of things devices, the convergence layer 102 comprises edge gateways, the edge gateways are carriers for realizing edge calculation and can run edge gateway programs, and the carriers comprise other devices with calculation capacity, such as a PC (personal computer) computer, an industrial personal computer, a mini computer and an internet of things gateway box. The network layer 103 includes various network devices, which may be routers or the like. The platform layer 104 is an internet of things cloud platform, the internet of things cloud platform can be composed of servers, the servers can be a physical server or a logic server formed by a plurality of physical servers in a virtual mode, the servers can also be a server cluster formed by a plurality of interconnected communication servers, and each functional module can be respectively distributed on each server in the server cluster. The application layer 105 includes a number of clients through which a user may remotely access the internet of things cloud platform.

In this embodiment, the system 100 collects service data through the device awareness layer 101, analyzes the service data through the edge gateway in the convergence layer 102, performs pre-calculation on the service data, makes a real-time response, and backs up local data to the platform layer 104 when the edge gateway is idle, so as to provide remote access to a user of the application layer 105. The platform layer 104 serves as a processing core of the system 100, and is responsible for analyzing device data, managing a data channel of an edge gateway, analyzing and calculating data, and the like. The convergence layer 102 and the device sensing layer 101 are in the same local area network, and nearby service data collected by the internet of things device is calculated to share the calculation pressure of the platform layer 104.

Specifically, the internet of things devices in the device sensing layer 101 may specifically be smart home devices, such as an air conditioner box, a smart band, a sleep monitor, a wearable hearing aid, and the like. All internet of things devices constitute the device sensing layer 101. Each internet of things device is used for collecting service data, for example, the service data includes the temperature and the operation mode of an air conditioner, heartbeat data of a user, sleep time of the user, and the like.

When accessing the device awareness layer 101, the internet of things device may be networked first, and then perform security authentication and associated user registration to the platform layer 104 through the convergence layer 102 and the network layer 103. The Internet of things equipment needs to acquire network capacity through a distribution network access router. Some thing networking devices (such as air conditioner box, intelligent bracelet etc.) do not have the input peripheral hardware, can realize joining in marriage the net through third party APP to this type of equipment, can adopt smartconfig or AP mode to realize joining in marriage the net specifically. The smart tconfig realizes the distribution network specifically that the internet of things equipment monitors all messages in the network in a promiscuous mode; the third party APP encodes the SSID and the password into the UDP message and sends the UDP message through a broadcast packet or a multicast packet; and the Internet of things equipment receives the broadcast packet or the multicast packet to obtain a UDP message, decodes the UDP message to obtain a correct SSID and a correct password, and then actively connects the route of the specified SSID to access the network. The AP mode realizes that the network is specifically distributed, and the thing networking device is in the AP mode, runs the intelligent terminal of third party APP is the station mode, and intelligent terminal connects constitute local area network behind the AP of thing networking device, this intelligent terminal send need connect the SSID and the password of route extremely thing networking device to make this thing networking device initiative go to connect appointed route, join in marriage the network in order to accomplish. The third-party APP is a preset application program and runs on the intelligent terminal.

The operation of the network distribution of the Internet of things equipment can be performed when the Internet of things equipment is firstly accessed into the local area network, and the networking is not required to be repeated after the Internet of things equipment is networked. When new internet of things equipment is added into the equipment sensing layer 101, the method can be also adopted to network the newly added internet of things equipment.

After the internet of things device is networked, an authentication command can be sent to the platform layer 104, so that the internet of things cloud platform corresponding to the platform layer 104 associates the internet of things device with the registered user.

It is worth to be noted that the internet of things device and the edge gateway are located in the same local area network after being networked, and the internet of things device and the edge gateway are successfully authenticated on the internet of things cloud platform and are associated with the registered user of the internet of things cloud platform.

After the Internet of things equipment is networked and associated with the registered user, the Internet of things equipment is also used for realizing the communication between the edge gateway and each piece of Internet of things equipment by connecting the edge gateway. When the internet of things equipment is connected with the edge gateway, the edge gateway generally sends a broadcast packet, and the internet of things equipment is connected with the edge gateway according to the broadcast packet. However, when there are many internet of things devices, there are different IP network segment problems, so that the broadcast communication scheme in the local area network cannot be used, and therefore, in some embodiments, the connection between the internet of things device and the edge gateway may be implemented through the third party APP. Specifically, the third party APP acquires edge gateway information from the Internet of things cloud platform, and sends a network switching command request to the Internet of things cloud platform according to the acquired edge gateway information; the Internet of things cloud platform sends a network switching command to the Internet of things equipment according to the network switching command request, and the Internet of things equipment receiving the network switching command is connected to the edge gateway corresponding to the network switching command request.

The internet of things equipment which establishes communication connection with the edge gateway can comprise one or more than one piece of internet of things equipment, the number of the edge gateways can also be one or more than one piece of internet of things equipment, one edge gateway corresponds to one or more than one piece of internet of things equipment, and the internet of things equipment which is connected with the same edge gateway is accessed into the same local area network.

It can be understood that the edge gateway has a network capability, and can be used as a server to support various internet of things devices to access in a client form.

Therefore, in some embodiments, after the edge gateway establishes a connection with each piece of internet of things equipment, the edge gateway is further configured to receive an authentication command sent by the piece of internet of things equipment, and verify the validity of the piece of internet of things equipment according to the authentication command, so as to implement service data communication with the piece of internet of things equipment.

The Internet of things equipment connected with the edge gateway needs to complete authentication on the Internet of things cloud platform, and the Internet of things equipment after authentication can obtain the IP and the port of the edge gateway to be connected. And the Internet of things equipment is connected with the edge gateway according to the IP and the port. After the internet of things equipment is successfully connected with the edge gateway, the internet of things equipment sends an authentication command to the edge gateway to determine whether the internet of things equipment meets a preset access requirement, if so, the edge gateway sends an access authentication success indication to the internet of things equipment, and therefore the internet of things equipment can be in service data communication with the edge gateway. Wherein the preset access requirement comprises: the Internet of things equipment is the equipment which supports access by the edge gateway, and the Internet of things equipment and the edge gateway both correspond to the same registered user.

The internet of things equipment is the equipment which the edge gateway supports access, namely the internet of things equipment is accessed to the internet of things cloud platform to be authenticated and authenticated, and only the internet of things equipment which passes the authentication and authentication can be accessed to the edge gateway. And the authentication needs the matching of the Internet of things cloud platform. Specifically, for example, after the internet of things device comes online, the internet of things device may be associated with a specific user on the internet of things cloud platform, then the internet of things cloud platform pushes data of the internet of things device to an edge gateway below the user, the edge gateway locally may synchronize the data of the internet of things device with the internet of things cloud platform in real time, and finally, the edge gateway determines whether the internet of things device can access the edge gateway according to local internet of things device data, wherein when the internet of things device data meets the requirement of the edge gateway, the internet of things device may access the edge gateway.

The fact that the Internet of things equipment and the edge gateway correspond to the same registered user means that the Internet of things equipment and the edge gateway are associated with the same registered user on the Internet of things cloud platform.

In this embodiment, the identity of the internet of things device accessing the edge gateway is verified through the two conditions, so that the security of the edge gateway and the accessed data is improved, and malicious devices are prevented from accessing the edge gateway. In addition, the accessed Internet of things equipment and the edge gateway correspond to the same registered user, so that the management of the Internet of things cloud platform on the user and the equipment is facilitated.

In some embodiments, before the edge gateway verifies the validity of the internet of things device, the edge gateway is further configured to establish a communication channel with the internet of things device according to a connection request sent by the internet of things device. After the Internet of things equipment has network capacity, sending a connection request to the edge gateway to connect the edge gateway, wherein the connection request is triggered after the Internet of things equipment receives a network switching command sent by the Internet of things cloud platform after passing through the authentication of the Internet of things cloud platform. In this embodiment, the connection request includes identification information of the internet of things device, and the establishing, by the edge gateway, the communication channel with the internet of things device according to the connection request sent by the internet of things device includes: and the edge gateway associates the identification information with an equipment channel so as to communicate with the Internet of things equipment through the equipment channel. The edge gateway is provided with at least one equipment channel, and the edge gateway can associate the identification information of the Internet of things equipment with the equipment channel, so that the edge gateway communicates with the corresponding Internet of things equipment through the equipment channel. The identification information is the only identification registered by the Internet of things equipment on the Internet of things cloud platform. The identification information and the device channel may be in a one-to-one or many-to-one relationship, that is, one identification information corresponds to one device channel, or a plurality of identification information corresponds to one device channel. The edge gateway can issue an instruction to the internet of things device according to the device channel. The edge gateway may control the opening and closing of the device channel. The corresponding relationship between the device channel and the identification information may be stored locally or on an internet of things cloud platform, and a user may manage the corresponding relationship between the device channel and the identification information.

When the internet of things equipment is the equipment which can be accessed by data and passes the verification of the edge gateway, the internet of things equipment and the edge gateway can carry out data transmission through the equipment channel. The internet of things equipment can transmit data to the edge gateway, and the edge gateway can also send commands to the internet of things equipment.

Specifically, the edge gateway is configured to receive service data sent by the internet of things device, and perform data processing on the service data. The receiving the service data sent by the internet of things equipment and the data processing of the service data comprise:

The protocol header is mainly used for adding some common information, for example, the common information is used for indicating what protocol the current protocol is. Part of information of the protocol header can be used for checking the legality of the protocol and identifying the Internet of things equipment for sending the data packet. In addition, the sticky packet phenomenon in the process of transmitting the TCP transmission content can be solved by utilizing the information of the protocol header, wherein the sticky packet phenomenon refers to that a plurality of packet data sent by a sender are pasted into one packet when being received by a receiver, and the header of the next packet data is next to the tail of the previous packet data from the view point of a receiving buffer area. The common ways to solve the TCP packet sticking phenomenon include two approaches, the first is to format the data, i.e. each piece of data has a fixed format (start and end); the second type is the transmission length, that is, the length of each piece of data is transmitted together when each piece of data is transmitted, for example, the first 4 bits of each piece of data can be selected as the length of the data, and the start and the end of each piece of data can be judged according to the length when the application layer processes. Then, the resolution of the TCP sticky packet phenomenon using the information of the protocol header may be to define a start symbol and an end symbol of each piece of data in the protocol header, or to define a length of each piece of data, so that the TCP sticky packet phenomenon can be resolved according to the information defined by the protocol header. The data area is used for storing data to be transmitted, the data area can be json format data inside the data area, and can also be byte data generated by an XML definition template, wherein the json format is a light-weight data exchange format, and the json format data can be suitable for equipment with high computing capacity. The XML definition template generates byte data, that is, data in an XML format, which is a plain text format and is suitable for devices with weak computing power. The protocol check bit is mainly used for detecting a content error problem occurring in the network transmission process, and the content error problem can cause abnormal operation of the edge gateway.

In this embodiment, the protocol header includes a length of the data area and a resolution flag indicating a resolution mode. The length of the data area is used for indicating the length of the service data stored in the data area, and the analysis identifier is used for indicating the data format of the service data stored in the data area.

The extracting the service data from the service message according to the length of the data area is that: and extracting service data with a preset length from the service message, wherein the preset length is stored in the protocol header.

The service data extracted according to the protocol check bit check is that: and checking whether the extracted service data is complete or not through the protocol check bit, whether errors occur in the network transmission process or not and the like. Therefore, abnormal operation of the edge gateway caused by content errors can be avoided, and the stability of the equipment is improved. The content of the protocol check bit may specifically be a CRC code generated according to the content of the protocol header and the data area, and the service data is checked by the CRC code. In other embodiments, hamming codes may be used in place of CRC codes, which may check for errors but not correct them, and when device protocol data changes during transmission, hamming codes may be used to know where protocol errors are and correct the erroneous bits.

The step of converting the extracted service data into service data in a preset data format according to the analysis identifier is that: and converting the extracted service data into service data in a preset data format according to the data format of the service data indicated by the analysis identifier. For example, the analysis identifier indicates that the service data in the data area is in a json format, and at this time, the edge gateway directly converts the extracted service data into json data according to the analysis identifier; for another example, the parsing identifier indicates that the service data in the data area is in an XML format, and at this time, the edge gateway selects a predefined template (e.g., an XML template) to parse and extract the obtained service data, and then generates corresponding json data from the parsed service data.

In some embodiments, the protocol header further includes a version number of the preset communication protocol. Wherein the version number corresponds to one or more parsing templates (such as multiple XML templates) for parsing or encapsulating the service data in the data area. Wherein, the converting the extracted service data into service data in a preset data format according to the analysis identifier further comprises: and selecting an analysis template corresponding to the version number according to the analysis identifier, and converting the extracted service data into service data in a preset data format.

For example, the parsing flag indicates that the service data in the data area is in an XML format, and it is known that the edge gateway prestores multiple XML templates, where the content and the content length of the data area respectively defined by the multiple XML templates have a certain difference. And selecting the parsing template corresponding to the version number according to the parsing identifier, namely selecting one or more XML templates corresponding to the version number from the plurality of XML templates. And finally, analyzing and converting the extracted service data according to the selected XML template. The method comprises the steps that an xstream. In this embodiment, the service data is parsed by using the XML template, so that some internet of things devices with poor computing capabilities can be supported to access the edge gateway.

The edge gateway is further configured to associate the version number with the internet of things device. Therefore, the analysis template corresponding to the Internet of things equipment can be obtained according to the version number. When the internet of things equipment sends a service message to the edge gateway based on the format corresponding to the preset communication protocol each time, the version number of the preset communication protocol can be carried in the protocol header corresponding to the format, the edge gateway associates the version number with the internet of things equipment, and when the edge gateway communicates with the internet of things equipment, a corresponding analysis template can be selected according to the version number, so that the edge gateway can package a issued instruction based on the analysis template or analyze a received instruction.

The service message is transmitted through the format corresponding to the preset communication protocol, so that on one hand, the abnormal data can be intervened and processed in time; on the other hand, the method can support the Internet of things equipment with poor computing capability to access the edge gateway; finally, security and flexibility are higher.

The edge gateway may also feed back a processing result of the data to the user, for example, provide the running state of the internet of things device (for example, whether the device is online or offline or has a fault, etc.) for the user, the service data acquired by the internet of things device (for example, the current heart rate and body movement of the user, whether the user is lying in bed, etc.), and data alarm information (for example, if the heart rate of a certain user exceeds a set alarm value, the data is synchronized to a relevant worker in time to alarm), etc.

Further, the edge gateway can synchronize the obtained data to the internet of things cloud platform. The edge gateway may store the service data and the processing result of the service data locally, and may sequentially store data according to the type of the internet of things device and the timestamp corresponding to the service data. When the edge gateway network is unobstructed, locally stored data are synchronized to the internet of things cloud platform, the internet of things cloud platform can perform offline calculation based on the received data, for example, a user sleep quality report can be generated according to the received user sleep data, and the user quality report can be pushed to a user.

In this embodiment, the edge gateway is mainly used for edge computing to compute data collected by the internet of things device nearby. The data of the internal equipment of the edge gateway can be synchronous with the data of the Internet of things cloud platform, and when one edge gateway is abnormal, the data collected by the Internet of things cloud platform and the Internet of things equipment can be continuously used for calculation. When the data of the edge gateway and the data of the internet of things cloud platform are synchronized, two strategies can be adopted, the first strategy is to directly burn data which are not changed frequently (such as a protocol template of factory equipment of a company) into edge gateway software when the internet of things equipment leaves a factory, therefore, the edge gateway is not required to obtain the data through a network, the dependence of the edge gateway on the network is reduced, and the processing speed is accelerated. The second is for data which is not burned into the edge gateway, the data cannot be known before leaving the factory, and the data can be obtained by the edge gateway according to an active pull strategy. The edge gateway may obtain related data based on the two manners, when the obtained data needs to be updated, the internet of things cloud platform may notify the edge gateway of updating the data based on a TCP protocol, and the data to be updated may be downloaded by the edge gateway from the internet of things cloud platform through the network layer 103.

In summary, the edge gateway may be connected to an internet of things device, perform security authentication on the accessed internet of things device, obtain service data from the internet of things device connected to the edge gateway, perform data calculation on the service data, and display a result of the data calculation to a user. When the edge gateway is configured, internal data of the edge gateway can be synchronized with an internet of things cloud platform; in data transmission, data can be transmitted based on a preset protocol format, the protocol is parsed in the form of an XML template, and supported protocols can be managed and updated.

In some embodiments, the edge gateway may implement the functions described in the foregoing embodiments through a device access module, a data buffering module, a service processing module, and a service presentation module running thereon, and specifically, as shown in fig. 2, is an architectural design of the convergence layer. The equipment access module, the data buffer module, the service processing module and the service display module realize the connection and data access of the Internet of things equipment, the calculation of data transmitted by the Internet of things equipment and the display of data calculation results based on the architecture. The equipment access module is used for receiving the service data and converting the service data into a preset data format according to a communication protocol of transmission data; the data buffer module is used for caching the service data converted into the preset data format; the business processing module is used for analyzing and processing the business data converted into the preset data format to generate display data; and the service display module is used for feeding back the display data to the user.

The device access module can convert the service data into json format. The data buffer module can buffer high concurrent flow data besides the service data converted into the preset data format. The display data generated by the service processing module may be specifically graphical data, such as a user sleep condition analysis table, which includes sleep time, movement times, whether snoring occurs, and the like of the user. The service display module may obtain the display data from the service processing module based on an http protocol, and display the display data to a user. The service display module can also provide an APP or WEB access interface based on an http protocol so that a user can access data at any time and know the relevant conditions of the monitored user.

The device access module further comprises at least one device channel, and the edge gateway is further configured to acquire identification information registered by the internet of things device on the platform layer, associate the identification information with the device channel, and enable the edge gateway to communicate with the internet of things device corresponding to the identification information according to the associated device channel. The edge gateway serves as an edge node, the Internet of things equipment can transparently transmit data through the edge gateway, the edge gateway can also judge whether the Internet of things equipment has the capacity of executing specific services according to the data, and if yes, the edge gateway can establish special connection with the Internet of things equipment. Therefore, the internet of things equipment and the edge gateway can be associated through the equipment channel and the identification information, and when the edge gateway needs to drive the internet of things equipment, the corresponding internet of things equipment can be found according to the equipment channel and the identification information.
