Detailed Description
Hereinafter, only certain exemplary embodiments are briefly described. As will be recognized by those of skill in the pertinent art, the described embodiments may be modified in various different ways without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following describes related technologies of the embodiments of the present application. The following related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application.
In one related technology before the application, in order to access the internet of things equipment using different access protocols to the internet of things server, data interaction between the internet of things equipment and the internet of things server is achieved, the internet of things server uses a protocol conversion gateway to convert industry or private protocols used by different internet of things equipment into a unified MQTT protocol, and then data interaction is carried out. The MQTT protocol is a lightweight communication protocol based on a Publish/Subscribe (publich/subscnibe) mode, and has wide application in the field of Internet of things. Fig. 1 is a schematic diagram showing a scheme of implementing internet of things device access according to the related art. For example, vendor 1's internet of things device uses private access protocol 1 and vendor 2's internet of things device uses private access protocol 2. When the Internet of things equipment of a manufacturer 1 is accessed to an Internet of things server and data is transmitted to the Internet of things server, a protocol conversion gateway needs to convert a private access protocol 1 used by the Internet of things equipment into an MQTT protocol used by the Internet of things server; similarly, when the internet of things equipment of manufacturer 2 is accessed to the internet of things server, the protocol conversion gateway also needs to convert the private access protocol 2 into the MQTT protocol. In the process that the internet of things server transmits data to the internet of things device, the protocol conversion gateway needs to convert the MQTT protocol into an industry or a private access protocol (for example, private access protocol 1 and private access protocol 2) used by the internet of things device. The protocol conversion gateway needs to adapt to various protocols, and also needs to debug the conversion among the protocols, so that the cost of accessing the Internet of things equipment is increased, the protocol conversion speed is low, the efficiency is low, and the efficiency of accessing the Internet of things equipment into the Internet of things server is affected.
In view of this, the embodiments of the present application provide a new access scheme for devices of the internet of things, so as to solve all or part of the problems in the related art. In order to more clearly show the access scheme of the internet of things device provided in the embodiment of the present application, a specific application example of the scheme of the embodiment of the present application is given as follows. Fig. 2 is a schematic diagram illustrating an access scheme of an internet of things device according to an embodiment of the present application. As shown in fig. 2, a protocol developer of an internet of things equipment manufacturer (for example, manufacturer 1, manufacturer 2 and manufacturer N) uploads a protocol plug-in after development to an internet of things server, and the internet of things server dynamically loads the received protocol plug-in an equipment access layer, so that the internet of things server deploys the protocol without stopping the machine, and the protocol is used for realizing that each internet of things equipment accesses the internet of things server based on the protocol developed by each manufacturer to perform data interaction. After the internet of things server finishes the protocol deployment, the internet of things devices of the manufacturer 1, the manufacturer 2 and the manufacturer N can use the corresponding protocols (for example, the private access protocol 1, the private access protocol 2 and the private access protocol N) to perform data interaction with the internet of things server. Compared with the related art, the technical scheme of the embodiment of the application can realize that each piece of equipment of the Internet of things is directly connected to the service end of the Internet of things, so that the time and cost of protocol conversion are saved, the equipment of the Internet of things can be connected to the service end of the Internet of things in higher efficiency, the data interaction with the service end of the Internet of things can be completed in higher speed, the service end of the Internet of things can dynamically load more protocol plug-ins under the condition of no shutdown, and the horizontal expansion capacity is improved.
An embodiment of the application provides an access method 300 of an internet of things device, which is applied to an internet of things server, wherein the internet of things server can be deployed in public cloud, private cloud, hybrid cloud and other environments. The internet of things device access method 300 of the present application will be described below with reference to fig. 3. Fig. 3 is a flowchart illustrating an internet of things device access method 300 according to an embodiment of the present application. As shown in fig. 3, the method 300 for accessing the internet of things device may include the following steps S301 to S303. The steps S301 to S303 will be described in detail with reference to specific embodiments.
First, the process advances to step S301. In step S301, a protocol plug-in corresponding to an access protocol is acquired.
In an embodiment, an internet of things device manufacturer may store a protocol plug-in corresponding to an access protocol in a server, and allow an internet of things server to obtain the protocol plug-in. In another embodiment, the internet of things equipment manufacturer may upload the protocol plug-in to the target server of the internet of things server through FTP (File Transfer Protocol ). The internet of things equipment manufacturer can also upload the protocol plug-in to the target server of the internet of things server through HTTP (Hyper Text Transfer Protocol ). The above description of the protocol plugin mode corresponding to the access protocol obtained by the server of the internet of things is only exemplary, and a person skilled in the art can select the mode of obtaining the protocol plugin according to the actual situation.
In some embodiments, the internet of things server issues a protocol service programming interface (Service Programming Interface, SPI) specification defined by the internet of things server, based on which the protocol plug-in is developed. The internet of things server can issue the protocol service programming interface specification on a file server or a webpage, and allows each internet of things equipment manufacturer to acquire the protocol service programming interface specification by accessing the file server or the webpage. The internet of things server may also issue protocol service programming interface specifications to various internet of things device vendors by way of network transmission (e.g., mail, TCP communication).
In some embodiments, the protocol service programming interface specification includes at least one of a codec specification, a security authentication specification, a sticky unpacking specification. The protocol service programming interface specification may include a series of interface functions, further including the name of the function, the function description of the function, the function requiring the incoming parameters and the return value of the function.
In some embodiments, some of the internet of things devices use a battery to supply power, and have high power saving requirements, so that the internet of things devices use binary format data to reduce electricity consumption. Some of the internet of things servers use JSON (JavaScript Object Notation, JS object numbered musical notation) format data, and other of the internet of things servers use XML (Extensible Markup Language ) format data. In an embodiment, the data in JSON format is used by the internet of things server, and the internet of things server needs to define a coding and decoding specification to realize conversion between a data format used by the internet of things device and a data format used by the internet of things server. For example, the codec specification includes a series of interface functions for the interconversion of binary format data and JSON format data. For example, the name of the decoding function in the codec specification may be Decode, the function of the decoding function is to convert binary data into JSON data, the incoming parameter is a binary data value, and the return value is JSON data.
In some embodiments, during transmission of TCP (Transmission Control Protocol ), TCP splits or assembles packets according to the actual situation of the transmission buffer. For example, the sending end sends two data packets P1 and P2 to the receiving end, and since TCP is a connection-oriented protocol, no packet loss occurs, and if the receiving end receives only one data packet, the data packet contains information of two data packets P1 and P2, which is sticky; if the receiving end receives two data packets, the first data packet contains the complete P1 packet and part of the P2 packet, and the second data packet contains the remaining content of the P2 packet, which is unpacking. Therefore, the service end of the internet of things also needs to define a sticking and unpacking specification for analyzing complete data sent by the internet of things equipment.
The internet of things device vendor may develop and debug protocol plugins based on the protocol service programming interface specification. For example, an internet of things equipment manufacturer belongs to the hydrology industry, the hydrological monitoring internet of things equipment produced by the manufacturer needs to follow the data transmission standard of SL651-2014 hydrological monitoring data communication protocol, and the manufacturer can develop a protocol plug-in based on various interface functions in the protocol service programming interface specification, so that the functions of the protocol plug-in meet the data transmission standard of hydrological monitoring. The internet of things equipment manufacturer also needs to debug the developed protocol plug-in, so that the protocol plug-in can be guaranteed to operate normally, and the internet of things equipment manufacturer can optimize the performance of the protocol plug-in, so that the protocol plug-in can operate with higher efficiency.
In some embodiments, the internet of things server may define a protocol service programming interface specification based on a Java language, and corresponding to the protocol service programming interface specification, an internet of things device manufacturer needs to develop a protocol plug-in using the Java language, and the protocol plug-in may be in a form of a Jar (Java Archive) file. In another embodiment, the service end of the internet of things may define a protocol service programming interface specification based on a C language, and the corresponding protocol plug-in needs to be developed by an equipment manufacturer of the internet of things by using the C language, and the protocol plug-in may be a DLL (Dynamic-Link Library) file. The protocol plug-in developed by the internet of things equipment manufacturer can also comprise a package sticking and unpacking module, a coding and decoding module and a security authentication module corresponding to the package sticking and unpacking specification, the coding and decoding specification and the security authentication specification in the protocol service programming interface specification. The above description of the internet of things service end defining the protocol service programming interface specification based on a programming language is merely exemplary, and a person skilled in the art may select the programming language of the protocol service programming interface specification according to the actual situation.
Next, step S302 is entered. In step S302, the protocol plug-in is loaded, and a protocol port is configured to deploy the access protocol.
In some embodiments, the internet of things server dynamically loads the received protocol plug-ins using a hot-loading technique. For example, the internet of things server obtains a protocol plug-in Jar developed by an internet of things equipment manufacturer based on Java language, and the internet of things server dynamically loads the protocol plug-in Jar in a JVM (Java Virtual Machine ) of the internet of things server by using Java ClassLoader, so that the protocol plug-in Jar is loaded under the condition that the internet of things server is not stopped, the access protocol is deployed, and the horizontal extension of the protocol is realized.
In some embodiments, the internet of things server and the internet of things device manufacturer need to agree on a port for the protocol developed by the internet of things device manufacturer. The port can be defined by the service end of the Internet of things or defined by the manufacturer of the equipment of the Internet of things, and only the two parties negotiate agreements. Ports are used to distinguish to which process a received packet in a computer should be forwarded. Each access protocol corresponds to one port, and the same port cannot correspond to multiple protocols. The port numbers are integers ranging from 0 to 65535. For example, the internet of things server may agree with an internet of things equipment manufacturer in a hydrologic industry to select 10001 a port corresponding to a protocol developed by the internet of things equipment manufacturer, where the internet of things equipment of the manufacturer may access the internet of things server through an IP address of the internet of things server and the port number, and perform information interaction. For example, the IP address of the service end of the internet of things is 110.242.101.101, the internet of things device in a hydrology industry needs to report the water level height of the current river, and the internet of things device can be connected to the service end of the internet of things through 110.242.101.101:10001 and transmits the current river water level height information.
In some embodiments, the internet of things server configures a protocol port on its access gateway. The access gateway is a bridge for information interaction between the Internet of things equipment and the Internet of things server, and can provide routing service and forward the received request message of the Internet of things equipment to a service node corresponding to the Internet of things server. When the request messages sent by the internet of things equipment are too many, the access gateway can also prevent the request messages of the internet of things equipment in a current limiting or fusing mode so as to ensure the availability of the whole internet of things server. And configuring a protocol port on the access gateway, so that the access gateway can expose the port, and the access gateway can wait for receiving the message transmitted by the Internet of things equipment from the port.
In some embodiments, the internet of things server starts the access gateway and listens to the protocol port. After the access gateway is started by the Internet of things server, monitoring whether the Internet of things equipment transmits a message through the port or not through the port exposed outwards by the access gateway. If a message transmitted by the internet of things equipment is received, the internet of things server can process the received message based on a deployed protocol.
Next, step S303 is entered. In step S303, based on the deployed access protocol, a message transmitted when the internet of things device accesses the internet of things server is processed.
In some embodiments, the internet of things server decodes, responds, encodes, and sends the message sent by the internet of things device through the deployed access protocol, so as to complete the service request of accessing the internet of things device to the internet of things server.
Another embodiment of the present application provides an access method 400 of an internet of things device, which is applied to an internet of things server. The internet of things device access method 400 of the present application will be described below with reference to fig. 4. Fig. 4 is a flowchart illustrating an internet of things device access method 400 according to another embodiment of the present application. As shown in fig. 4, the method 400 for accessing the internet of things device may include the following steps S401 to S403. The steps S401 to S403 will be described in detail with reference to specific embodiments.
First, the process advances to step S401. In step S401, a message transmitted by the internet of things device is acquired through a protocol port.
In some embodiments, the internet of things server receives a message transmitted by the internet of things device by monitoring a configured protocol port. For example, the port configured by the internet of things server for an internet of things equipment manufacturer in the hydrologic industry is 10001, and the internet of things server can monitor 10001 ports continuously to receive messages transmitted by the internet of things equipment of the manufacturer.
Next, step S402 is entered. In step S402, an access protocol corresponding to the deployment of the protocol port is determined.
In some embodiments, multiple access protocols (e.g., hydrologic industry access protocol, smart furniture industry access protocol, internet of vehicles industry access protocol) are deployed at the internet of things server, which access protocol is needed to be used by the internet of things server to process the message according to the port from which the message was received. For example, the port number of the message received by the internet of things server is 10001, and the internet of things server determines that the access protocol is the access protocol of the hydrological industry according to the corresponding relationship between the protocol port and the access protocol, and the internet of things server needs to process the message transmitted by the received internet of things device by using the access protocol.
Next, the process advances to step S403. In step S403, the message transmitted by the internet of things device is decoded based on the deployed access protocol.
Decoding is the process of converting information from one form or format to another. Encoding is the inverse of decoding. For example, some of the internet of things devices use a battery to supply power, so that the power saving requirement is high, and the internet of things devices use binary format data; the internet of things server has no limitation on resources, and is JSON format data, so after the internet of things server receives binary data of the internet of things equipment, a codec module in a deployed access protocol is required to convert the binary data into JSON data which can be processed by the internet of things server. For example, an internet of things device manufactured by an internet of things device manufacturer in the hydrology industry transmits binary data such as 0x00110111 to an internet of things server, the internet of things server decodes the first four bits 0011 of the binary data into a water level by using a codec module in an access protocol in the hydrology industry, decodes the last four bits of the binary data into 7, and integrally decodes the binary data into JSON data such as { water level:7}, so that the internet of things server can further process the JSON data.
In some embodiments, the internet of things device is connected with the internet of things server through a TCP transmission channel, and the internet of things server also needs to perform a package pasting or package unpacking process on a message transmitted by the internet of things device based on a deployed access protocol. When the internet of things equipment and the internet of things server are connected through the TCP transmission channel, the sticking or unpacking refers to that when the internet of things equipment transmits a message, the TCP divides the data packets according to the actual condition of the buffer area, and in the condition, one complete data packet can be split into a plurality of data packets to be sent, and a plurality of small data packets can be packaged into one large data packet to be sent. Therefore, the service end of the internet of things can process the received data packet by using the sticky packet unpacking module in the deployed access protocol so as to acquire a complete message transmitted by the internet of things equipment.
Still another embodiment of the present application provides an access method 500 for an internet of things device, where the method is applied to an internet of things server. In an embodiment, the access method 500 is performed after the access method 400. The internet of things device access method 500 of the present application will be described below with reference to fig. 5. Fig. 5 is a flowchart illustrating an internet of things device access method 500 according to yet another embodiment of the present application. As shown in fig. 5, the method 500 for accessing an internet of things device may include the following steps S501 to S502. The steps S501 to S502 will be described in detail with reference to specific embodiments.
First, the process advances to step S501. In step S501, a message type of the decoding result is determined, and a response message is generated based on the message type.
In some embodiments, the internet of things server generates the corresponding response message based on the type of the message of the decoding result according to its processing logic. For example, a hydrologic internet of things device sends a PUBLISH message to an internet of things server, where the PUBLISH message includes the current water level of a river. After the internet of things server decodes the message, it is identified that the message is of a PUBLISH type, the internet of things server can store the river water level height information in the PUBLISH message, and return a PUBLISH message to the internet of things device to tell the internet of things device that the publication is successful. For another example, an intelligent speaker internet of things device sends a SUBSCRIBE message to an internet of things server, where the SUBSCRIBE message includes a subscription theme for a river water level height. After the internet of things server decodes the message, it is identified that the message is of a SUBSCRIBE type, the internet of things server can return SUBACK (subscription confirmation) message to the internet of things equipment, tell the internet of things equipment that subscription is successful, and push river water level height information to the internet of things equipment at preset time.
In some embodiments, authentication information corresponding to the internet of things device is stored in the internet of things server, and before the internet of things server generates the response message based on the message type of the decoding result, if the message type is a security authentication type, the internet of things server needs to verify the decoding result according to the authentication message of the internet of things device. The internet of things server can register the internet of things equipment needing to be accessed to the internet of things server in advance, and after the registration is completed, the internet of things server can also store authentication information (for example, a secret key, a product serial number, an MAC address (Media Access Control Address, a media access control address)) of the internet of things equipment. In an embodiment, the internet of things device may use its own key to digitally sign the product serial number, and send the digital signature as a message body of the security authentication message to the internet of things server, where the internet of things server verifies the digital signature in the security authentication message according to the stored authentication information of the internet of things device. If the verification is passed, the internet of things server can issue an Access Token to the internet of things device, and the internet of things device can carry the Access Token in a message interacted with the internet of things server later, so that the internet of things device can indicate that the internet of things device has obtained the Access authorization of the internet of things server; if the verification is not passed, the server side of the Internet of things disconnects the connection with the equipment of the Internet of things, and the access of the equipment of the Internet of things is refused.
Next, step S502 is entered. In step S502, the response message is encoded based on the deployed access protocol, and the encoded response message is sent to the internet of things device.
In some embodiments, the message generated by the server of the internet of things is in JSON format, the device of the internet of things can only identify binary data, the server of the internet of things needs to use a codec module in a deployed access protocol to encode the JSON data into the binary data, and the binary data is returned to the device of the internet of things.
