Technical Field

The invention relates to the technical field of Internet of things, in particular to a data interaction method of an Internet of things cloud platform and equipment, a data interaction device of the Internet of things cloud platform and the equipment, a data interaction system of the Internet of things cloud platform and the equipment, a computer storage medium and computing equipment.

Background

The Internet of Things (IoT) concept is a network concept that extends and expands its user end to any article to article for information exchange and communication based on the Internet concept. The internet of things connects all articles with the internet through the information sensing equipment to exchange information, namely, the articles are related to each other, so that intelligent identification and management are realized. The internet of things is being widely applied in the fields of smart home and the like.

The internet of things cloud platform can help a developer (namely, an equipment manufacturer) to easily realize equipment access and equipment connection, realize remote monitoring and operation of internet of things equipment, and provide a comprehensive internet of things solution. However, in the existing internet of things cloud platform solution, in order to implement data interaction between a cloud and a device (smart device), a corresponding data communication protocol needs to be established for each type of device. Moreover, even if the devices are of the same type, if there are differences between the device products of different manufacturers, different data communication formats may need to be established for the devices of the same type produced by different manufacturers. This results in a large amount of labor cost being wasted to formulate a data communication protocol, and a developer also needs to encode each type of device according to the data communication protocol, resulting in slow development speed, high development cost, and high maintenance cost. In addition, when the device interacts with the cloud, if the configuration of the device is high, the device may generally interact with the cloud in a json format. However, if the device configuration is low and the performance is limited, json format data cannot be analyzed, and at this time, the device needs to interact with the cloud terminal by adopting a special data encoding format.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The inventor finds that in the existing solution of the internet of things, in order to realize data interaction between a cloud and a device (smart device), a corresponding data communication protocol needs to be established for each new type of device product before the device product is accessed. For example, for an intelligent socket, corresponding protocols need to be formulated for attribute reporting, behavior events and the like, including a protocol for reporting data (assumed to be named as/S00/1/1), a protocol for opening a socket (/ S01/1/1), a protocol for closing a socket (/ S01/1/0), and the like. This results in a large amount of labor cost being wasted to formulate the data communication protocol, and the developer also needs to encode each device according to the data communication protocol, resulting in slow development speed, high development cost, and high maintenance cost.

In addition, when the device interacts with the cloud, if the performance of the device is limited and json format data cannot be analyzed, a special data encoding format needs to be adopted for interacting with the cloud, which is not beneficial to unifying data interaction formats.

In order to solve the technical problem, the embodiment of the invention provides a data interaction method for an internet of things cloud platform and equipment. Fig. 1 shows a flowchart of a data interaction method applied to an internet of things cloud platform and a device on a cloud platform side according to an embodiment of the present invention. Referring to fig. 1, the method is applied to the cloud platform side, and may include at least the following steps S102 to S106.

Step S102, after the intelligent device is connected to the cloud platform, receiving a device model constructed by the intelligent device and uploaded by the intelligent device and a uniform data coding format which is configured by the intelligent device and interacts with the cloud platform, wherein the device model defines attributes, behaviors and events of the intelligent device.

And step S104, receiving the data in the unified data coding format reported by the intelligent equipment, and processing the received reported data according to the equipment model of the intelligent equipment and the unified data coding format.

And S106, generating issuing data in a unified data coding format according to the equipment model of the intelligent equipment and the unified data coding format, and issuing the issuing data to the intelligent equipment.

It should be noted that the order of step S104 and step S106 may be interchanged, and the present invention is not limited thereto.

According to the data interaction method of the Internet of things cloud platform and the equipment, the equipment model is built, the data interaction between the intelligent equipment and the Internet of things cloud platform is carried out by adopting the uniform data coding format, the waste of labor cost caused by the fact that different data communication formats are formulated for each type of equipment in the prior art is avoided, meanwhile, an equipment developer does not need to know details of data coding to code each type of equipment, the development rhythm is accelerated, and the development cost and the maintenance cost are reduced.

The smart devices mentioned above may include air conditioners, air purifiers, refrigerators, televisions, table lamps, etc. The internet of things cloud platform may include one or more server clusters. The intelligent device can access the Internet of things cloud platform through a server (called a browser) which receives connection in a server cluster on the Internet of things cloud platform.

The device model mentioned in step S102 above may be constructed on the smart device side by the following two ways:

in the first mode, a device developer writes standard development documents according to device types on the intelligent device side for construction.

In the second mode, initial models of various types of equipment are pre-constructed by the Internet of things cloud platform, the initial models are provided for equipment developers through specific interfaces, and then the equipment developers select and refine parameters in the initial models according to the equipment types to generate final equipment models.

In the embodiment of the present invention, attributes (attribute, which may also be referred to as state), behaviors (which may also be referred to as service, i.e., device behaviors executed in response to a call of a cloud platform), and events (events) of a smart device are defined in the constructed device model. For example, for an air purifier, the attributes defined in the device model may include PM2.5 values, gear, bulb on/off state, functional mode, etc., the behavior may include operations of turning on, turning off, adjusting gear, setting mode, etc., and the event may include human body sensor detecting human body movement, etc.

In addition, the unified data coding format for interaction between the intelligent device and the cloud platform can be configured on the intelligent device side according to the data analysis performance of the intelligent device.

In an alternative embodiment, the unified data encoding format may include a json format or a specified binary encoding format. The specified binary coding format mentioned here is not called xlink format, and is a format for coding data by using binary, and the requirement on the data analysis performance of the device is low, and the method is particularly suitable for configuring low-performance devices.

Further, for an intelligent device with high data analysis performance, a uniform data coding format of interaction between the intelligent device and the internet of things cloud platform is preferably configured to be a json format. For the intelligent device with low data analysis performance, the unified data coding format for interaction between the intelligent device and the internet of things cloud platform is preferably configured to be an xlink format.

Further, when the unified data encoding format configured by the intelligent device is the json format, in step S104, after the data in the json format reported by the intelligent device is received, the received reported data is directly processed according to the device model and the json format of the intelligent device. Meanwhile, in step S106, the assignment data in the json format may be directly generated according to the equipment model and the json format of the intelligent device, and the assignment data in the json format may be issued to the intelligent device.

When the unified data encoding format configured by the intelligent device is an xlink format, in step S104, after receiving the xlink format data reported by the intelligent device, the received xlink format reported data is analyzed and converted into json format data according to the device model of the intelligent device and the xlink format, and then the json format data obtained by conversion is processed. Meanwhile, in step S106, the original issuing data in json format is encoded according to the device model and xlink format of the intelligent device to generate issuing data in xlink format, and then the generated issuing data in xlink format is issued to the intelligent device.

In an optional embodiment, when the unified data encoding format configured by the intelligent device is an xlink format, in step S104, after receiving xlink format data reported by the intelligent device, the method further includes a step of performing format validity verification on the received reported data. Through format validity verification, the accuracy of subsequent data analysis is guaranteed, and the data interaction efficiency of the intelligent device and the cloud platform is improved.

In an optional embodiment, the data reported by the smart device may include at least one of attribute reporting data, event reporting data, and service call response data. The issued data of the cloud platform may include service call data and/or attribute setting data.

The following describes, by specific examples, situations of performing data interaction with an internet of things cloud platform by using a json format and an xlink format respectively.

Firstly, a device model of an intelligent device (e.g., a color desk lamp) to be accessed is constructed, and device attributes such as color (color), brightness (brightness), on-off state (light switch) and the like, device behaviors such as set _ work mode (set _ work) and the like, and events such as light-on events (open _ light-event) and the like are defined in the device model.

If the configuration of the intelligent device to be accessed is high and the intelligent device to be accessed has high data analysis performance, the data interaction format of the intelligent device to be accessed can be configured into a json format. Specific examples of json format data of the intelligent device interacting with the internet of things cloud platform under different conditions are listed below.

When the cloud platform calls the service to the intelligent device, the issued data may be:

{

"id":125000,

"version":1,

"data":{"color":"#00ff00","brightness":2},

"action":"dsl.service.set_workmode"

}

correspondingly, the service call response data sent by the intelligent device to the cloud platform is as follows:

{

"id":125000,

"version":1,

"data":{},

"action":"dsl.service.set_workmode",

"errno":0

}

when the attribute setting of the intelligent device is performed on the cloud platform side, the data issued by the cloud platform may be:

{

"id":100000,

"version":1,

"data":{"brightness":5,"color":"#ff0000","lightswitch":1},

"action":"dsl.property.set"

}

when the intelligent device reports the attributes to the cloud platform, the reported data may be:

{

"id":100000,

"version":1,

"data":{”brightness”:5,”color”:“#ff0000”,“lightswitch”:1},

"action":"dsl.property.post"

}

when the intelligent device reports an event to the cloud platform, the reported data may be:

{

"id":100000,

"version":1,

"data":{},

"action":"dsl.event.post.open_light_event"

}

if the configuration of the intelligent device to be accessed is low and only has low data analysis performance, the data interaction format of the intelligent device to be accessed can be configured into an xlink format.

In one embodiment, an xlink formatted packet may include six portions, a header (head), a length (length), a version number (version), a device identification (id), a payload (payload), and a checksum (checksum).

In practical applications, the byte length of each part can be defined as follows:

head	length	version	id	payload	checksum
						2byte	2byte	1byte	4byte	N byte	1byte

wherein the byte length of the payload part is determined according to the definition of the equipment model.

Length is the sum of the byte lengths of version, id, payload, and checksum, i.e., Length + version + id + payload + checksum.

checksum＝(length+version+id+payload)&0xff。

Checksum refers to the accumulation of the number of transmission bits, and when the transmission is finished, the receiver can determine whether all data has been received according to the number. If the values match, the transfer is said to have been completed. The following schematic lists the calculation procedure for checksum:

in an xlink-format packet, payload data is described in a payload section. Specifically, for different interaction scenarios, the payload section may adopt the following corresponding data format.

For the case of attribute setting or attribute reporting, the payload part may adopt a data format as follows:

action

attr1_id

value1

attr2_id

value2

attrN_id

valueN

1byte

N byte

1byte

N byte

1byte

N byte

for the case of service invocation, service invocation response or event reporting, the payload part may adopt the following data format:

action	serviceid/eventid	errno	value1	value2	valueN
						1byte	1byte	1byte	N byte	N byte	N byte

wherein, only when the service call is responded, the payload part of the data packet contains errno. When the errno value is 0x00, the call is successful, otherwise, the call is failed.

The action in the above table is used to identify the purpose of part of the payload data in the xlink format data packet, including attribute reporting (dsl. performance. post), attribute setting (dsl. performance. set), service calling (dsl. service), event reporting (dsl. event. post), and the like.

In practical applications, action can be defined as follows:

dsl.property.post＝0x00

dsl.property.set＝0x01

dsl.service＝0x02

dsl.event.post＝0x03

the byte length of each value (value1, value2, value n) in the table above is determined by the type of data it defines.

Typically, the data type of value and the corresponding relation of the byte length can be shown as the following table:

further, the following constant definitions may also be made in the device model:

by the definition of the xlink format, the interactive data are coded by a simple binary system, and the conversion between the data in the binary coding format and the data in the json format is realized, so that the method is particularly suitable for data interaction between intelligent equipment with limited performance and an Internet of things cloud platform.

Correspondingly, fig. 2 shows a flowchart of a data interaction method applied to an internet of things cloud platform and a device on an intelligent device side according to an embodiment of the present invention. Referring to fig. 2, the method is applied to the smart device side, and may include at least the following steps S202 to S210.

Step S202, an equipment model is built according to the equipment type of the intelligent equipment, and the attribute, the behavior and the event of the intelligent equipment are defined in the equipment model.

Step S204, configuring a unified data coding format for interaction between the intelligent equipment and the Internet of things cloud platform.

And S206, after the Internet of things cloud platform is accessed, uploading the constructed equipment model and the configured uniform data coding format to the Internet of things cloud platform.

And S208, generating data in a unified data coding format according to the equipment model, and reporting the data to the Internet of things cloud platform.

Step S210, receiving data in a unified data coding format issued by the Internet of things cloud platform, and analyzing the received data according to the equipment model.

It should be noted that the order of step S208 and step S210 may be interchanged, and the present invention is not limited thereto.

In an alternative embodiment, the above-mentioned unified data encoding format may comprise a json format or a specified binary encoding format. The designated binary encoding format referred to herein is not referred to as xlink format, and its specific definition is as described above.

Further, the above step S204 may be embodied as:

for the intelligent device with low data analysis performance, configuring a uniform data coding format of the intelligent device interacting with the internet of things cloud platform into the specified binary coding format (namely, xlink format).

In the above, various implementation manners of each link of the embodiments shown in fig. 1 and fig. 2 are introduced, and an implementation process of the data interaction method between the internet of things cloud platform and the device of the present invention is described in detail through a specific embodiment.
