For example, the computer device may be the computer device 110 shown in fig. 1, and the cloud may be the cloud 120 shown in fig. 1. As shown in fig. 3, the method for constructing the device model of the internet of things device may include the following steps:
in step 301, a model framework of the device model to be built is obtained.
In the embodiment of the present disclosure, the model framework is used to indicate each model element corresponding to the device model, where the model element is a sub-model corresponding to the model element, and the model element is used to represent a device feature of the internet of things device.
Alternatively, the computer device may obtain a model frame generated from an editing operation received in the model frame editing interface.

The event element may be information that the operation state of the device is changed, information that the transmission instruction of the device has been executed, or the like. The relationship element may be information of a one-to-one relationship of the device with other devices.
For example, referring to fig. 4, which shows a schematic diagram of a model framework related to an embodiment of the present disclosure, a computer device obtains the model framework of the internet of things device shown in fig. 4 through editing by a JSON Schema tool. The Internet of things equipment can be connected with the cloud end through the model framework, and data exchange can be carried out between the Internet of things equipment and the cloud end. The Internet of things equipment can upload the measuring point information in the dynamic measuring point elements to the cloud, can interact various parameters in the service elements with the cloud, and can upload parameters in the event elements to the cloud.
For example, please refer to fig. 5, which shows a schematic diagram of a model framework when a device to be constructed according to an embodiment of the present disclosure is a fan, as shown in fig. 5, in an internet of things environment, the fan device may upload a rotation speed parameter in a dynamic measurement point element of the fan device to a cloud terminal through the device model, the cloud terminal processes and analyzes data to control the fan device to execute an acceleration instruction, when a rotation speed of the fan device reaches a certain threshold value or the fan fails, the fan device sends alarm data for alarming that the rotation speed of the fan is over-speed or the fan fails to the cloud terminal for processing, and the cloud terminal controls the fan device to perform a next operation.
In step 302, the computer device obtains the parent model from a library of standard models according to the model framework.
Alternatively, the parent model may be a model stored locally on the computer device, or may be a previously built model, or may be a standard model already published stored in a central repository.
The parent model obtained by the computer device comprises various element models in the original parent model.
For example, referring to fig. 6, which shows a model schematic diagram of a fan device according to an embodiment of the present disclosure, as shown in fig. 6, a constructed fan model includes a basic information element, a static attribute element, a dynamic measurement point element, a service element, an event element, and a relationship element, the fan device model shown in fig. 6 may be used as a standard model, and meanwhile, the model may also be used as a parent model, and a model of a fan device capable of shaking head is continuously constructed on the basis of the fan model. Referring to fig. 7, which shows a schematic model diagram of a shakable fan device according to an embodiment of the present disclosure, as shown in fig. 7, a fan device model is used as a parent model of the model building, and the shakable fan model is built on the basis of an original fan device model.
In step 303, the computer device obtains the preset and stored model elements according to the model framework.
Optionally, each model element includes at least one of a model standard element and a model custom element.

Wherein, the model standard element is stored in the central warehouse and is a published standard element. The corresponding model standard element stored in the central repository can be queried and called for to join the model framework through the $ ref capability in the json schema tool.
For example, referencing a dynamic measurement point model in model elements of model a to standard model elements can be achieved by editing the following code in the JSONSchema tool:
the specific definition of the model standard element location is also defined by JSON Schema. The specific codes are as follows:

The central warehouse is a completely public standard warehouse, the central warehouse can be divided into two parts, one is a standard model library, the standard model library is a standard warehouse for providing public standard models, and a model designer can copy or inherit the standard models in the standard model library. The other is a model standard element library which is used for providing public standard elements, and a model designer can combine the equipment model based on the standard elements.
2) And when each model element comprises the model self-defining element, acquiring the model self-defining element edited and uploaded by a user through a model element self-defining interface.
