Description

Interactive virtual device and system of Internet of things equipment and control console and storable medium

Technical Field

The application relates to the technical field of intelligent control, in particular to an interactive virtual device, an interactive virtual system and a storable medium for Internet of things equipment and a control console.

Background

In the prior art, due to the fact that a network is unstable, equipment is frequently connected with and disconnected from the network. When the application program sends a request for acquiring the current equipment state, the equipment is disconnected and the equipment state cannot be acquired, but the equipment is successfully connected in the next second, and the application program cannot correctly initiate the request.

If multiple programs simultaneously request to acquire the device state, if the device network is stable, many application programs request to acquire the device state, the device needs to respond for many times according to the request, and even if the response results are the same, the processing capacity of the device is limited, and the situation that the device is requested for many times cannot be loaded.

For the case of device disconnection, the device is frequently on and off due to unstable network of the device, and when the application program sends a control command to the device, the device is disconnected, and the command cannot be sent to the device.

In all of the above cases, the state of the device cannot be obtained in real time, the performance is consumed when the state of the device is read, and a conflict may occur when a command is sent.

As shown in fig. 1, the internet of things device and console interaction system according to the present invention includes a communication unit 110, a virtual unit 120, and a data flow unit 130.

The communication unit 110 is used for information communication among the devices, the virtual units, and the console.

The above-mentioned dummy cell 120 serves as an intermediate unit for associating the offline device with the online console. The virtual unit corresponds to the only equipment, and more than one virtual unit is arranged and is independent.

The virtual unit in this embodiment includes a desired unit 121 and a report unit 122.

The data stream unit 130 performs information communication between the device, the virtual unit, and the console together with the communication unit when the device is online or offline with the same data format content.

In this application, the data streaming unit 130 includes:

a first data flow unit 131 for updating information into a virtual unit;

and a second data streaming unit 132 for updating the state information of the virtual device.

The data formats of the first data stream unit and the second data stream unit are the same, and both the first data stream unit and the second data stream unit contain equipment information and console information.

As a specific embodiment, each device accessed in the system has one and only one device shadow (i.e. the virtual unit 120), and the device may acquire and set the device shadow to synchronize the device attribute values, where this synchronization may be shadow synchronization to the device or device synchronization to the shadow.

In order to facilitate communication between data, the internet of things platform predefines two topics for each device to realize data flow, and the defined topics are presented in a fixed format. I.e. the content format of the first data stream unit 131:

topic/shadow/update/${productKey}/${deviceName}。

and the equipment and the application program issue a message to the Topic, and the Internet of things platform updates the state in the message to the virtual unit after receiving the message of the Topic.

Content format of the second data stream unit 132:

topic/show/get/$ { productKey }/$ { devicenname }, the device shadow updates the state to the Topic, and the device subscribes to the message of the Topic.

Taking a specific bulb device under the product bulb No. 1 as an example, pid is 10000; rightbulb, the device publishes two topics defined by a subscription with QoS ═ 1, illustrating the communication between the device, the device shadow and the application.

1) The equipment actively reports the state:

a. when the light bulbs lightbulb are networked, the device reports the latest state to the virtual unit by using the Topic/shadow/update/10000/lightbulb.

Transmitted JSON message format:

reporting parameter description:

a method: indicating the type of operation when a device or application requests a device shadow. When an update operation is performed, method is a mandatory field and is set to update.

And (5) state: status information indicating that the device sent to the device shadow. Ported is a mandatory field and state information is updated synchronously to the ported portion of the device shadow.

version: representing version information in the device shadow check request. And only when the new version is larger than the current version, the device shadow receives the request of the device side and updates the version of the device shadow to the corresponding version.

b. When the equipment shadow receives the state reported by the bulb, the shadow document is successfully updated.

c. After updating the device shadow, the device shadow will return the result to the device (bulb), i.e. send a message to/shadow/get/10000/lightbulb, and the device subscribes to the Topic.

If the update is successful, the message sent to the Topic is:

if the update fails, the message sent to the Topic is:

error code description:

errorCode	errorMessage
		400	an incorrect JSON format.
401	The shadow data lacks method information.
		402	The shadow data lacks a state field.
403	The version value in the shadow data is not a number.
		404	The shadow data lacks a ported field.
405	The ported attribute field in the shadow data is empty.
		406	Method in shadow data is an invalid method.
407	The shadow content is empty.
		408	The number of ported attributes in the shadow data exceeds 128.
409	A shadow version conflict.
		500	The server handles the exception.

2) The application changes the device state:

a. the application program issues an instruction to the equipment shadow to change the state of the bulb;

b. the application program sends an update request, and the device shadow updates the document;

c. after the equipment shadow is updated, sending a message to a topic/shadow/get/10000/lightbulb, returning a result to the equipment, wherein the returned result is determined by the equipment shadow to form the result;

d. the bulb is online and subscribes to topoic/shadow/get/10000/lightbulb, receives the message and updates the status according to the desired value in the request document, changing the bulb color to green. If the time stamp judges that the instruction is out of date, the updating can be selected not to be carried out;

e. after updating, sending a message to a topoic/show/update/10000/lightbulb to report the latest state;

f. after the reported state is successful, the device shadow is updated synchronously, and the updated shadow document is as follows:

3) the device actively acquires the shadow content of the device:

a. the bulb acquires the latest state of the bulb stored in the shadow of the equipment, and sends a fixed message to the topic/shadow/update/10000/lightbulb, wherein the specific message is as follows;

b. when the device shadow receives the message, the device shadow sends the message to the topic/shadow/get/10000/lightbulb, the bulb subscribes to the topic to obtain the message, and the message content is as follows:

and the SDK completes the action of acquiring the device Shadow by using the API IOT _ Shadow _ Pull.
