With the above figures, certain embodiments of the invention have been illustrated and described in more detail below. The drawings and the description are not intended to limit the scope of the inventive concept in any way, but rather to illustrate it by those skilled in the art with reference to specific embodiments.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

The internet of things technology is an information bearer based on the internet, a traditional telecommunication network and the like, and all common physical objects which can be independently addressed form an interconnected network. In the embodiment of the invention, the corresponding technology and the existing problems are explained by combining the Internet of things cloud application and the Internet of things equipment in an interactive and developing manner.

In the prior art, the internet of things cloud application needs to remotely request the internet of things equipment to realize functions on the internet of things equipment, such as turning on an air conditioner, setting temperature, starting or stopping a local scene, and the like. Usually, an instruction needs to be designed for each function in a communication protocol between an internet of things device (end for short) and an internet of things cloud application (cloud for short). Meanwhile, for each function, corresponding content needs to be developed for each function in the internet of things device, the internet of things cloud application and the corresponding communication system to support the function. For example, for the operation of starting a local scene, if the cloud communication protocol is MQTT protocol, a topic (topic) is newly added, such as: the device comprises a device, a scene, a start and a service platform, wherein the device represents the equipment of the internet of things, the device Id represents the identification information of the equipment of the internet of things, the position of the scene represents a certain application on the corresponding equipment of the internet of things to be requested, the scene represents a local scene application, the position of the start represents a certain function of the corresponding application on the equipment of the internet of things to be requested, and the start represents the local scene application; if the end cloud communication protocol is the WIFI basic protocol, a command word is added, such as START _ SCENE, to indicate that the local SCENE application is started.

Similarly, for another example, for the operation of stopping the local scene, if the end cloud communication protocol is the MQTT protocol, a topic is added, for example: /device/{ deviceId }/scene/{ scene id }/stop; if the end cloud communication protocol is the WIFI basic protocol, a command word such as STOP _ SCENE is added. The meanings of the two are similar to the above, and are not repeated herein for brevity.

Therefore, in combination with the above description, with the implementation manner in the current technology, when a new service or function is added to the internet of things device and the internet of things cloud application needs to remotely request the new service or function on the internet of things device, an instruction corresponding to the new service or function needs to be extended to a communication protocol between the end clouds, and corresponding contents are developed in the end, the cloud, and the corresponding communication system to support the new service or the new function, so that flexibility and efficiency in developing a new service for end cloud communication are low.

For the problems in the prior art, the inventor finds, after research, that a new service or function is added to an internet of things device, and an application of an internet of things cloud needs to remotely request a newly added service or function on the internet of things device, if it is not necessary to extend content corresponding to each newly added service or function in a communication protocol between end clouds for each newly added service or function, a universal interface request is extended in the communication protocol between the end clouds, all newly added services or functions between the end clouds can be realized through the universal interface request, and it is not necessary to extend content corresponding to each newly added service or function in a cloud forwarding device, which is helpful to improve flexibility and efficiency of developing new services of end cloud communication.

The network architecture of the communication method between the cloud and the internet of things device provided by the embodiment of the invention is introduced below. As shown in fig. 1, a network architecture corresponding to the data search method provided in this embodiment includes a cloud application device 1, a cloud forwarding device 2, and an internet of things device 3, which are used for requesting an internet of things device interface. The internet of things device 3 may be at least one internet of things device, and two internet of

things devices

31 and 32 are shown in fig. 1. It should be understood that the internet-of-things device is a device that can be remotely requested to be controlled for the cloud application device 1. The invention does not limit the type of the internet of things equipment. The cloud application device 1 is provided with an interface for requesting the internet of things device to realize a target new function, the internet of things device 3 is provided with an interface capable of realizing a target new service or corresponding to the function, the cloud application device 1 sends a request of the internet of things device target new function to the cloud forwarding device 2, the cloud forwarding device 2 forwards the request to the internet of things device 3, the internet of things device 3 analyzes the corresponding request and realizes the corresponding target new function, an execution result of the target new function is forwarded to the cloud forwarding device 2, and the cloud forwarding device 2 can forward the execution result of the target new function to the cloud application device 1.

Implement one

Fig. 2 is a schematic flow chart of a communication method between a cloud and an internet of things device according to a first embodiment of the present invention, and as shown in fig. 2, an execution main body of the embodiment of the present invention is a communication device between the cloud and the internet of things device, and the communication device between the cloud and the internet of things device is located in a cloud forwarding device, so that the communication method between the cloud and the internet of things device according to the present embodiment includes the following steps.

Step 201, the cloud forwarding device receives a new function execution request sent by the cloud application device.

The newly added function execution request comprises target newly added function related information of the target Internet of things equipment. The information related to the target added function represents information that needs to be indicated to the internet of things device to achieve the target added function, and can be used for bearing information such as a device, an interface, a request type and parameters needing to be input, which correspond to the target added function.

It can be understood that the cloud forwarding device is used for finding out which internet of things device can complete the new function in the new function execution request, and sending the new function to the corresponding internet of things device. Therefore, the newly added function execution request at least includes identification information corresponding to the target internet of things device.

It should also be understood that, although the cloud forwarding device provided in this embodiment does not need to pay attention to what the new function is, after the cloud forwarding device forwards the new function execution request to the target internet of things device, the target internet of things device finds an interface for implementing the target new function according to the new function execution request, and invokes a corresponding interface to implement the target new function. Therefore, the new function execution request may include the target new function related information of the target internet of things device. The information related to the target added function may include an application, an interface, and corresponding parameters for implementing the target added function.

Step 202, packaging the related information of the target added function, generating a universal interface request, and marking the request type of the universal interface request.

The generic interface may be understood as a software interface developed for at least one new function, and the software interface may be understood as a generic software interface for different functions. The request type of the universal interface request is different from the request types of other existing functions, and the universal interface request type is a universal interface request type and represents a request type corresponding to a universal software interface request corresponding to the newly added function. That is, after at least one new function is added to the target internet of things device, the cloud application device may generate the universal interface request based on the information related to the at least one new function, so that the target internet of things device calls the corresponding application and interface to implement the at least one new function based on the universal interface request, in order to realize the at least one new function by the target internet of things device.

It should be understood that the generic interface requests that the corresponding content is predefined, e.g., may be well defined in the protocol.

And step 203, sending the universal interface request marked with the request type to the target internet of things equipment.

The universal interface request comprises identification information corresponding to the target Internet of things equipment, so that the universal interface request marked with the request type can be sent to the target Internet of things equipment according to the identification information corresponding to the target Internet of things equipment.

The universal interface request is used for indicating target equipment in the target Internet of things equipment to apply and execute a target new function.

The communication method between the cloud and the internet of things equipment provided by the embodiment is applied to the cloud forwarding equipment, and comprises the steps of receiving a newly added function execution request sent by cloud application equipment, wherein the newly added function execution request comprises target newly added function related information of target internet of things equipment; packaging the related information of the target newly added function to generate a universal interface request, and marking the request type of the universal interface request; and sending a universal interface request marked with a request type to the target Internet of things equipment, wherein the universal interface request is used for indicating the target equipment in the target Internet of things equipment to apply and execute the target newly added function. Due to the fact that a function is added, a software interface corresponding to the added function needs to be correspondingly added to the cloud forwarding device, and a corresponding instruction needs to be expanded in the end cloud communication protocol to conveniently support the function, so that flexibility and efficiency of developing new end cloud communication services are low. Therefore, in the embodiment of the invention, the corresponding content of the universal interface request only needs to be expanded once in the end cloud communication protocol, so that the cloud forwarding equipment can directly generate the universal interface request when receiving the newly added function execution request, and the corresponding content does not need to be expanded aiming at the newly added function, thereby improving the flexibility and efficiency of developing new end cloud communication services.

Example two

Fig. 3 is a schematic flow chart of a data search method according to a second embodiment of the present invention, and as shown in fig. 3, the communication method between the cloud and the internet of things device according to the present embodiment is further refined in step 201 and step 202 based on the communication method between the cloud and the internet of things device according to the first embodiment of the present invention, where step 301 is further refined in step 201, and step 302 is further refined in step 202. The cloud forwarding device may include a forwarding end request proxy component and an M2M gateway, and the communication method between the cloud and the internet of things device provided in this embodiment includes the following steps:

step 301, receiving a new function execution request sent by the cloud application device by using a forwarding end request agent component.

It can be understood that the request agent component at the forwarding end is a predefined software interface, and is configured to receive the request for executing the new function, and convert the request for executing the new function into a request that can be recognized by the M2M gateway.

The forwarding terminal request agent component is a component specially receiving a new function execution request sent by the cloud application device. It is to be understood that, if the cloud application device sends the non-added function execution request, the non-added function execution request may be directly received by the M2M gateway.

And step 302, packaging the related information of the target newly added function by using the M2M gateway, generating a universal interface request, and marking the request type of the universal interface request.

Wherein, the information related to the target new function comprises: the target internet of things equipment identification information, the target equipment application identification information, the interface information of the target newly added function and the interface input parameters.

It can be understood that how to generate the content of the universal interface request according to the information related to the target newly added function is already defined in the end cloud communication protocol. The form of the target internet of things device identification information can also be understood as predefined.

Next, each piece of information of the target newly added function related information is described by taking an example that the end cloud communication protocol is MQTT. The target internet of things equipment identification information can be represented as deviceId, and the target internet of things equipment identification information can be information which uniquely represents the target internet of things equipment, such as the serial number, the name and the model of the target internet of things equipment; the target device application identification information may be represented as a service, and the target device application identification information may be information uniquely representing a certain application in the target internet of things device, such as "scene" (local scene application), by a serial number, a name, a model, and the like corresponding to the certain application in the target internet of things device; the interface information of the target newly added function may be represented as apiName, and may represent an API corresponding to a certain function corresponding to a certain application, such as "start" (start local scene application); the interface input parameter may be denoted params, which represents an input parameter required for a certain function as described above, and may be a list of a plurality of parameter value pairs (key-values).

It should be understood that one M2M gateway corresponds to a plurality of internet of things devices, and therefore, the information related to the target new function at least includes target internet of things device identification information, which is used by the M2M gateway to identify the internet of things device corresponding to the target new function.

It should be further understood that the target device application identification information, the interface information of the target newly added function and the interface input parameters are used for the subsequent internet of things device to determine the application corresponding to the realization of the target newly added function, and the corresponding interface information and the parameters required for realizing the target newly added function.

According to the communication method between the cloud and the internet of things device, a request agent component of a forwarding end is adopted to receive a new function execution request sent by a cloud application device; and packaging the related information of the target newly added function by adopting the M2M gateway to generate a universal interface request, and marking the request type of the universal interface request. Aiming at the new function, the cloud forwarding device deploys a universal interface specially used for receiving and sending related information of the new function, namely a forwarding end request proxy component, the forwarding end request proxy component sends an execution request of the new function to the M2M gateway, the forwarding end request proxy component and the M2M gateway both have pre-stored corresponding information for converting the related information of the new function into the universal interface request, and the M2M gateway only needs to convert the related information of the new function into the universal interface request and send the universal interface request to the Internet of things device.

EXAMPLE III

Fig. 4 is a schematic flow chart of a communication method between a cloud and an internet of things device according to a third embodiment of the present invention, and as shown in fig. 4, the communication method between the cloud and the internet of things device according to this embodiment is further detailed in step 302 on the basis of the communication method between the cloud and the internet of things device according to the second embodiment of the present invention, and then the communication method between the cloud and the internet of things device according to this embodiment includes the following steps:

step 401, packaging the information related to the target added function by using an M2M gateway through an MQTT or WIFI basic protocol to generate a universal interface request.

It should be understood that MQTT or WIFI base protocols may be understood as end cloud communication protocols.

Exemplarily, the process of encapsulating the information related to the target added function is described below by taking an end cloud communication protocol MQTT as an example. As described above, the information related to the target additional function may include: target internet of things device identification information (for example, deviceId), target device application identification information (for example, service), target newly added function interface information (for example, apiName), and interface input parameters (for example, params). And packaging the information related to the target added function into a message with a topic name (topic name) of 'Application Programming Interface (API) request', and generating a universal interface request. The generic interface request may be, for example,/device/{ device id }/API/req, and is issued to the topic (topic) corresponding to the generic API request. The api in the generic interface request of the above example may correspond to the interface information of the target newly added function in the foregoing, and req corresponds to the interface input parameter in the foregoing.

It should be understood that the end cloud communication protocol may extend the relevant information of the universal interface request, so that the internet of things device may analyze the packaged universal interface request to obtain the relevant information of the target new function.

Step 402, marking the request type of the universal interface request as the universal interface request type.

It should be understood that, in the embodiment of the present invention, the generic interface request type may be regarded as a type specifically set for the newly added function. The generic interface request type may correspond to, for example, the "generic API request" above.

The communication method between the cloud and the internet of things device provided by the embodiment is applied to a cloud forwarding device, and the information related to the target new function is encapsulated by adopting an M2M gateway and an MQTT or WIFI basic protocol to generate a universal interface request; the request type of the universal interface request is marked as the universal interface request type. In this embodiment, for a target new function, a cloud-end communication protocol MQTT or WIFI basic protocol may be used to expand the relevant content of a universal interface request, so that when the new function is added, because the M2M gateway has pre-stored the relevant content for converting the information related to the new function into the universal interface request, the M2M gateway only needs to convert the information related to the new function into the universal interface request, and does not need to re-expand the instruction corresponding to the new function in the cloud-end communication protocol, therefore, when the new function is added, the M2M gateway can quickly determine that the received request is a new function execution request, and can quickly generate the universal interface request, thereby improving the flexibility and efficiency of developing new services of cloud-end communication.

Example four

Fig. 5 is a schematic flow chart of a communication method between a cloud and an internet of things device according to a fourth embodiment of the present invention, and as shown in fig. 5, the communication method between the cloud and the internet of things device according to this embodiment is based on the communication method between the cloud and the internet of things device according to any one of the foregoing embodiments of the present invention, and further includes a process in which a cloud forwarding device processes a universal interface response type message, and then the communication method between the cloud and the internet of things device according to this embodiment includes the following steps:

step 501, an M2M gateway is adopted to receive an interface response message sent by a target internet of things device.

The interface response message may represent a response message with an execution result and a response type, which is fed back after the target new function is executed, and may be used to carry a device, an interface, a response type, and an execution result corresponding to the implementation of a certain function.

It should be understood that the interface reply message may be a general interface reply type message or other interface reply messages. The message of the generic interface response type corresponds to the message of the generic interface request type in the foregoing, and therefore, if the interface response message is a message of the generic interface response type, the interface response message may be used to indicate a response message with an execution result and a response type, which is fed back after the target addition function is executed, and may be used to carry, for example, a device, an interface, a response type, and an execution result corresponding to the target addition function.

Step 502, the interface response message is analyzed by the M2M gateway to obtain the response type of the interface response message.

In the embodiment of the present invention, the response type may be a generic interface response type corresponding to the generic interface request type or another interface response type. The universal interface response type can be understood as a response type corresponding to a universal interface response message obtained after the internet of things equipment processes the universal interface response message. And the universal interface response message represents a universal interface response message corresponding to the newly added function.

Step 503, if the response type of the interface response message is determined to be the general interface response type, sending the target new function execution result in the interface response message to the cloud application device through the forwarding end request agent component.

It is to be understood that the relevant content of the universal interface response may be predefined, for example, the relevant content of the universal interface response is defined in the cloud communication protocol, so that the M2M gateway may determine whether the type of the interface response message is the universal interface response type.

It should be understood that the forwarding end request agent component is a general interface specially used for receiving and sending the related information of the new function, and therefore, if the response type of the interface response message is determined to be the general interface response type, the forwarding end request agent component sends the target new function execution result to the cloud application device.

Fig. 8 is a schematic flowchart of a communication method between a cloud and an internet of things device according to a seventh embodiment of the present invention, and as shown in fig. 8, the communication method between the cloud and the internet of things device according to this embodiment is based on the communication method between the cloud and the internet of things device according to the fifth or sixth embodiment of the present invention, and further includes a process of processing a universal interface response type message by the internet of things device, and then the communication method between the cloud and the internet of things device according to this embodiment includes the following steps:

step 801, the interface request proxy component is adopted to obtain an interface response message, and the interface response message is sent to the connection component.

The interface request agent component is a component deployed on the internet of things device for a newly added function, can be used for analyzing the universal interface request, and can also be used for acquiring an interface response message and sending the interface response message to the connecting component.

It should be understood that the interface request proxy component is a component corresponding to a general interface that is specifically used for receiving and sending information related to the newly added function, and therefore, if it is determined that an interface response message is received, the interface request proxy component may send an execution result of the target newly added function to the cloud application device.

The description of the interface response message in the fourth embodiment is not repeated herein for brevity.

And 802, packaging the interface response message by adopting the connecting component to form a universal interface response message, and marking the response type of the universal interface response message as the universal interface response type.

For the response type of the interface response message, reference may be made to the related description in step 502, and details are not described herein for brevity.

For the convenience of understanding, the process of encapsulating the interface response message is illustrated here, and is similar to the process of encapsulating the information related to the target added function. For example, the interface response message may include: target internet of things device identification information (for example, deviceId), target device application identification information (for example, service), interface information of the target newly added function (for example, apiName), and a target newly added function execution result. And packaging the related information of the target newly added function into a message with a topic name (topic name) of 'Application Programming Interface (API) response', and generating an interface response message. The interface response message may be, for example,/device/{ device id }/API/resq, and is issued to the topic (topic) corresponding to the generic API request. The api in the above-mentioned example universal interface request may correspond to the interface information of the target new added function, and resq corresponds to the execution result of the target new added function.

The communication method between the cloud and the internet of things device provided by the embodiment is applied to the internet of things device, and the interface response message is acquired by adopting the interface request agent component and is sent to the connecting component; packaging the interface response message by adopting the connecting component to form a universal interface response message, and marking the response type of the universal interface response message as a universal interface response type; and sending the universal interface response message to cloud forwarding equipment by adopting the connecting component. Due to the fact that a function is added, the embodiment of the invention adopts a universal interface request to send corresponding information to the Internet of things equipment in the cloud forwarding equipment. Therefore, in this embodiment, for the target new function, at the internet of things device side, an "interface request proxy component" is deployed to forward the "universal interface response" message to the cloud forwarding device, and then the "universal interface response" message may be further processed by using the method of the fifth embodiment. As described in the fifth embodiment, since the relevant content of the "universal interface response" may be predefined, the cloud forwarding device may directly forward to the cloud application device, and it is not necessary to expand the corresponding content in the cloud forwarding device and the end cloud communication protocol again, thereby reducing the complexity of end cloud transmission and improving the flexibility and efficiency of developing new end cloud communication services.

Accordingly, the forwarding-end request proxy component 5 in the cloud forwarding device 2 receives the new function execution request.

In step 902, the forwarding-end request broker component 5 forwards the new function execution request to the corresponding M2M gateway 6.

In step 903, the M2M gateway 6 issues the new function execution request to the corresponding target internet of things device 31.

It is understood that the M2M gateway 6 may convert the new function execution request into a generic interface request that can be recognized by the target internet of things device 31.

It should be understood that the relevant content of the universal interface request may be predefined, for example, the content included in the universal interface request and the corresponding meaning of each content may be defined in the cloud-side communication protocol, which may be specifically referred to in the foregoing description of the second embodiment.

Accordingly, the connection component 7 of the target internet of things device 31 is configured to receive the generic interface request.

In step 905, the interface request broker component 8 forwards the generic interface request to the corresponding target device application 9.

In step 907, the interface request broker component 8 returns the execution result to the connection component 7.

In step 908, the connection component 7 returns the execution result to the M2M gateway 6.

In step 909, the M2M gateway 6 returns the execution result to the forwarder request broker component 5.

In step 910, the forwarding end request agent component 5 returns the execution result to the cloud application 11.

It should be understood that the specific details of the above process may be found in relation to other embodiments of the invention and will not be discussed herein for the sake of brevity.

According to the method provided by the embodiment, the newly added function execution request can be converted into the universal interface request, the universal interface request is predefined, and both the cloud forwarding device and the Internet of things device can identify the universal interface request, so that the cloud forwarding device does not need to expand corresponding contents for each newly added function for many times, and only needs to expand corresponding contents of the universal interface request for one time, and therefore, the complexity of end cloud transmission is reduced for the target newly added function, and the flexibility and the efficiency for developing new end cloud communication services are improved.
