Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The internet of things refers to the extension of the concept of the internet into the connection between physical devices and everyday objects. These devices embed electronics, network connections, and other forms of hardware (e.g., sensors), can communicate and interact with others over a network, and can be monitored remotely. For example, a smart home, which is one of the internet of things, covers one or more devices and appliances such as lighting fixtures, thermostats, home security systems, cameras, and other household appliances, and can control the devices and appliances in the smart home through the devices related to the smart home, such as a smart phone, a smart watch, a smart speaker, and the like. For another example, the internet of things can also be applied to the fields of agriculture, environmental monitoring and the like, for example, data about temperature, rainfall, humidity, wind speed, insect damage and soil content are collected through internet of things equipment.
For example, when a smart phone controls one or more electrical appliances, the devices in the internet of things generally need to have the same communication protocol or the communication protocols between the devices can be adapted. Because there are many manufacturers of devices in the internet of things, the manufacturers of devices in the internet of things can select different communication protocols such as CoAP protocol, MQTT protocol, DDS protocol, AMQP protocol, XMPP protocol, and the like. Under the limitation of a communication protocol operated by the equipment of the internet of things, the types of equipment which can be selected in the construction process of the internet of things are limited, which is not in line with the development trend of the internet of things.
In addition, due to the development of large-scale internet of things management platforms in various industries at present, service scenes are more and more complex; the variety of intelligent equipment is increasing; equipment manufacturers and service providers participating in a physical network management platform are more and more, and the situation of cross-platform and multi-protocol equipment cooperation is more and more common. In response to the heterogeneous internet of things protocol, the current general method is to adapt the device types and the protocol types in the platform one by one according to the requirements of service scenes, so as to achieve the purpose of mutual communication. The existing construction mode of the Internet of things and the information processing mode of the Internet of things can cause huge workload of adaptation protocols and increase construction cost and risk of the Internet of things, and if a novel protocol is accessed to a platform, reconstruction of the Internet of things system is certainly caused, meanwhile, various service logics and protocol adaptation logics in the platform are mutually interwoven, and great trouble is brought to system maintenance.
The main reasons for the high cost, poor expandability and poor maintainability of the internet of things are that there is a barrier to the information intercommunication among various internet of things communication protocols, for example, the internet of things communication protocol only can be executed by the internet of things equipment, and then the communication among the internet of things equipment with different internet of things communication protocols needs to be adapted manually. In order to implement information intercommunication between various communication protocols of the internet of things, fig. 1 is a method for processing information of the internet of things according to an embodiment of the present invention, and as shown in fig. 1, the method for processing information of the internet of things may include the following steps:
step S101: when registration requests of various Internet of things communication protocols are received, the various Internet of things communication protocols are mapped into a unified standard protocol, and mapping relations between the various Internet of things communication protocols and the standard protocol are stored;
in this step, the unified standard protocol refers to a predefined protocol format, for example, an expression manner of a protocol body included in the protocol, a format/expression manner of transmission information included in the protocol, and the like. The protocol body refers to instruction information included in the protocol, such as reporting data, turning on/off the device, and heating/cooling the device.
Specifically, the registration request is sent by each manufacturer or provider of the internet-of-things device, such as manufacturer 1, manufacturer 2, …, manufacturer n, etc. shown in fig. 2 through the registration protocol interface. Through the steps, various internet of things communication protocols such as an MQTT protocol, a CoAP protocol, a DDS protocol and the like shown in fig. 2 can be mapped into a unified standard protocol, and the mapping relation between the various internet of things communication protocols and the standard protocol can be stored in a database or directly cached.
The storage mode of the mapping relation may be: the mapping method includes mapping multiple internet of things communication protocols into a unified standard protocol, specifically mapping protocol bodies or transmission information or key information included in the multiple internet of things communication protocols into a unified expression format. For example, the protocol body indicating the on/off of the device in the communication protocol 1 of the internet of things is as follows: p0 denotes a closing device, P1 denotes an opening device; the protocol body for indicating the on/off of the equipment in the communication protocol 2 of the internet of things is as follows: power0 denotes a closing device, Power1 denotes an opening device; protocol body for indicating on/off of equipment in communication protocol 3 of internet of things: power0 denotes a closing device, power1 denotes an opening device; protocol body representing device on/off in standard protocol: power0 indicates turning off the device, and power1 indicates turning on the device; then P0 in the communication protocol 1 of the internet of things, Power0 in the communication protocol 2 of the internet of things, and Power0 in the communication protocol 3 of the internet of things can be mapped to Power of 0; and mapping P1 in the communication protocol 1 of the Internet of things, Power1 in the communication protocol 2 of the Internet of things and Power1 in the communication protocol 3 of the Internet of things to Power 1.
Step S102: and when the Internet of things information sent by the first Internet of things equipment is received, processing the Internet of things information based on the mapping relation, and providing a processing result for the second Internet of things equipment.
The information of the internet of things can be reported data or issued commands. The first internet of things device and the second internet of things device can be any one device in the internet of things, such as a lighting lamp, a thermostat, a home security system, a camera, a smart phone, a smart watch, a smart speaker and other devices, and are not particularly limited to a certain device in the internet of things.
Based on the mapping relation, the processing of the information of the internet of things can be realized as follows: the Internet of things information sent by the first Internet of things equipment is mapped into a format which can be read or identified by the second Internet of things equipment, and communication adaptation is not needed between the first Internet of things equipment and the second Internet of things equipment, so that communication between the Internet of things equipment with different Internet of things communication protocols is realized.
In the embodiment shown in fig. 1, since multiple communication protocols of the internet of things can be mapped into a unified standard protocol, and the mapping relationship between the multiple communication protocols of the internet of things and the standard protocol is stored; based on the mapping relation, the Internet of things communication protocol can be mapped to another Internet of things communication protocol by means of a unified standard protocol, communication barriers among different Internet of things protocols are broken, namely when the Internet of things information sent by the first Internet of things equipment is received, the Internet of things information is processed based on the mapping relation, and a processing result is provided for the second Internet of things equipment.
In addition, due to the mapping relation between various internet of things communication protocols and standard protocols, when new internet of things communication protocols are increased, the protocol or the internet of things equipment can be expanded only by constructing the mapping relation between the new internet of things communication protocols and the standard protocols, and the internet of things has expandability.
In addition, due to the mapping relation between various internet of things communication protocols and standard protocols, bridges among the internet of things devices are constructed, and the mutual interweaving of various business logics and protocol adaptation logics is avoided.
In this embodiment of the present invention, the mapping the plurality of internet of things communication protocols into the unified standard protocol in step S101 may include: mapping a plurality of protocol bodies included by each Internet of things communication protocol into corresponding key value pairs, wherein the mapping relation between the plurality of Internet of things communication protocols and the standard protocol comprises the following steps: a first mapping relationship between the plurality of protocol bodies and the key-value pairs.
Specifically, the specific implementation of mapping a plurality of protocol bodies included in each communication protocol of the internet of things to corresponding key value pairs may include: and mapping protocol bodies expressing the same function in various communication protocols of the Internet of things into the same key value pair.
An internet of things communication protocol may include a plurality of protocol bodies, such as a protocol body for reporting data, a protocol body for turning on/off a device, a protocol body for adjusting temperature, a protocol body for adjusting humidity, and the like.
The key-value pair is a ke10-value key-value pair, wherein ke10 represents the body or instruction of the protocol body; value characterizes the attribute value of the body or instruction of the protocol body. For example, the aforementioned power is 0 and power is 1, where power is an instruction to turn on/off the device, and 0 and 1 are attribute values of the instruction to turn on/off the device, where power is 0 to characterize to turn off the internet of things device; and (5) starting the Internet of things equipment by representing power as 1. The first mapping relationship between the plurality of protocol bodies and the key-value pairs may specifically be: protocol body 1 → key value pair 1 and protocol body 2 → key value pair 2, … in an internet of things communication protocol, such as P0 → Power0 (key value pair) in internet of things communication protocol 1, Power0 → Power0 (key value pair) in internet of things communication protocol 2, and Power0 → Power0 (key value pair) in internet of things communication protocol 3; p1 → Power ═ 1 (key-value pair) in the communication protocol 1 of the internet of things, Power1 → Power ═ 1 (key-value pair) in the communication protocol 2 of the internet of things, and Power1 → Power ═ 1 (key-value pair) in the communication protocol 3 of the internet of things.
In this embodiment of the present invention, the mapping the plurality of internet of things communication protocols into the unified standard protocol in step S101 may further include: the method includes the steps of mapping the same information in different formats transmitted by multiple internet of things communication protocols into corresponding information in a unified format, wherein the mapping relationship between at least one internet of things communication protocol and a standard protocol may further include: and a second mapping relationship between the same information in different formats and the corresponding information in the unified format. As shown in fig. 3, the internet of things device 1, the internet of things device 2, …, and the internet of things device n that transmit the reported data through different protocols, such as MQTT protocol, CoAP protocol, DDS protocol, etc., report the data through the device gateway and the data reporting interface, and according to the scheme provided by the embodiment of the present invention, the data reported by the different protocols, such as the data reported by MQTT protocol, the data reported by CoAP protocol, and the data reported by DDS protocol, can be mapped into the reported data of the standard protocol.
The information transmitted by the communication protocol of the internet of things or the reported data generally refers to data reported by the communication protocol of the internet of things, such as ambient humidity, ambient temperature, and the like. For example, the format of the environment temperature in the internet-of-things communication protocol 1 is T-25 ℃ (celsius), the format of the environment temperature in the internet-of-things communication protocol 2 is T-77 ° F (fahrenheit), and the unified format corresponding to the environment temperature is celsius, by using the solution provided by the embodiment of the present invention, the environment temperature T-25 ℃ (celsius) in the internet-of-things communication protocol 1 may be mapped to T-25 ℃ (celsius), and the environment temperature T-77 ° F (fahrenheit) in the internet-of-things communication protocol 2 may also be mapped to T-25 ℃ (celsius). Through the second mapping relation, the information transmitted by one Internet of things communication protocol can be mapped into the information with the uniform format, then the information with the uniform format can be re-mapped into the format in the Internet of things communication protocol subsequently, and the conversion of the information formats in different Internet of things communication protocols is realized, so that the communication among the Internet of things devices with different Internet of things communication protocols can be realized.
In an embodiment of the present invention, based on the mapping relationship in step S102, a specific implementation manner of processing the information of the internet of things may include: and converting the format of the reported data according to the second mapping relation aiming at the reported data of the first internet of things equipment with the internet of things information, and storing the reported data after the format conversion. For example, if the internet-of-things information is the ambient temperature T of the internet-of-things device 1 reported is 77 ° F (fahrenheit), according to the second mapping relationship, the ambient temperature T of the internet-of-things device 1 reported is converted into T of 25 ℃ (celsius) (fahrenheit), and the converted reported data is stored, so as to be provided to another internet-of-things device, that is, the second internet-of-things device in the following.
In the embodiment of the present invention, in order to enable internet of things devices with different internet of things communication protocols to successfully read data reported by any internet of things device, as shown in fig. 4, the processing of the internet of things information may further include the following steps:
step S401: receiving an information acquisition request sent by second networking equipment, wherein the information acquisition request comprises: the current operating protocol and protocol version of the second networking equipment;
wherein, the information acquisition request may further include: the characteristics of the information such as the source of the information, the time of reporting the information, etc. For example, the current operating protocol of the internet of things device 1 is MQTT protocol and the protocol version is 1.0. The information acquisition request sent by the internet of things device 1 is to acquire the ambient temperature detected and reported by the internet of things device n at the time point a.
Step S402: searching target data for the information acquisition request from the stored reported data after format conversion;
the searching process may perform searching based on the characteristics of the reported data, for example, a source of the environment temperature and the detection time of the environment temperature are located in the corresponding village in the stored environment temperature, so as to search for the environment temperature, and target data corresponding to the information acquisition request may be searched from the stored reported data after format conversion through the source of the environment temperature and the detection time of the environment temperature. For example, the information acquisition request sent by the internet of things device 1 is to acquire the ambient temperature detected and reported by the internet of things device n at the time point a, and the target data corresponding to the information acquisition request sent by the internet of things device 1 is found from the stored reported data after format conversion to be T-25 ℃ (temperature in celsius).
Step S403: and mapping the target data into protocol data matched with the current operating protocol and protocol version of the second networking equipment according to the second mapping relation.
For example, if the format of the environmental temperature in the current operating protocol of the internet of things device 1 is fahrenheit, the T-25 ℃ (celsius) found in step S403 may be mapped to a temperature T-77 ° F (fahrenheit) so that the internet of things device 1 can identify the acquired data. And communication among different communication protocols of the Internet of things is realized.
In this embodiment of the present invention, as shown in fig. 5, for a command issued by a first internet of things device to at least one second internet of things device for internet of things information, the processing of the internet of things information based on the mapping relationship may include the following steps:
step S501: mapping the command into a corresponding key value pair according to the first mapping relation;
for example, the internet of things device 3 sends a command P1 to the internet of things devices 4, 5, and 6, and the P1 may be mapped to a key value pair power of 1 through the first mapping relationship.
Step S502: according to the first mapping relation, further mapping the mapped key value pairs to a corresponding protocol object for each second networking device again;
for example, in this step, the key value pair Power is again mapped to 1 for the internet of things device 4 as the corresponding protocol body P1, mapped to the internet of things device 5 as the corresponding protocol body Power1, and mapped to the internet of things device 6 as the corresponding protocol body Power 1.
Step S503: and for each second networking device, performing encapsulation of the remapped protocol entity corresponding to the second networking device into the current operating protocol of the second networking device.
For example, the protocol body P1 is encapsulated in the current operating protocol of the internet of things device 4; packaging a protocol body Power1 into a current operating protocol of the Internet of things equipment 5; and encapsulating the protocol body power1 into the current operating protocol of the internet of things device 6.
The communication between different communication protocols of the internet of things is further realized through the process.
As shown in fig. 6, an embodiment of the present invention provides an internet of things information processing apparatus 600, where the internet of things information processing apparatus 600 may include: a protocol mapping interface 601, an information transfer interface 602, and a protocol addressing module 603, wherein,
the protocol mapping interface 601 is configured to map at least one internet of things communication protocol into a unified standard protocol when a registration request of the at least one internet of things communication protocol is received, and store a mapping relationship between the at least one internet of things communication protocol and the standard protocol;
