Embodiment 1

[0035] This embodiment discloses an industrial object model based on IoT middleware, which is composed of figure 1 It can be seen that its overall architecture includes a data layer, a service layer and a presentation layer.

[0036] Among them, the data layer is used for storing and caching data, and provides the data storage function for the service layer. Specifically, it includes: structure database, time series database, and cache database; among them, the structure database is used to store configuration data, such as industrial object model structure information; the time series database is used to store the collected data reported by the device / protocol service, such as the sensor device collects data every second The reported temperature information; the cache database is used to store frequently called data to improve viewing efficiency, such as model variable attributes, alarm trigger conditions and other information.

[0037] The service layer is the core layer, w...

Embodiment 2

[0040] This embodiment discloses a method for implementing an industrial object model based on IoT middleware, which specifically includes the following steps:

[0041] S1. Definition of industrial object model:

[0042] see figure 2 , the present invention defines the industrial object model from four aspects: identity information, attribute information, event information and service information.

[0043] Among them, the profile field of identity information is used to define the name, number, source, type and extensible information of the object model, including the field version: indicates the version number, code: indicates the unique number of the model, and name: the custom name of the model.

[0044] The attribute information properties defines the specific information and status of the device, in which the key field identifier is the unique identifier of the variable, which is unique in the entire industrial object model; name: variable name, accessMode: operation ty...

Abstract

The present invention claims to protect an industrial object model based on the Internet of Things middleware and an implementation method thereof. The model includes a data layer, a service layer and a presentation layer. The device / protocol access service cluster synchronizes various device configuration information to the object model management service cluster. , and then unify the equipment configuration information into an industrial object model for management, realize the abstract management of similar products, equipment variable collection and control, and solve the problem of inconsistent attribute definitions when many terminal equipment / facilities interact with the server in the existing industrial scene. Connecting difficult problems. The implementation method of the object model is described from the four dimensions of identity, attribute, event, and service. Terminal equipment or facilities are uniformly connected to the IoT middleware according to this object model method. The middleware cleans or calculates the data, and finally provides it to the third party. The tripartite platform completes data collection and processing, and can be applied to the definition of equipment and facility models in various industrial scenarios.

Description

technical field [0001] The invention relates to an industrial object model based on Internet of Things middleware and an implementation method thereof, which provides a standard data model for realizing Internet of Things data collection in industrial scenarios, and belongs to the technical field of Internet of Things. Background technique [0002] The continuous maturity of the Internet and traditional telecommunication networks provides the basic conditions for the ubiquitous networking of terminal equipment and facilities. With the development of information technology, the Internet of Things industry has become more and more popular in recent years. When various terminal devices or facilities are connected to the Internet, due to the different properties of different types of devices, in order to solve this problem, most companies usually do When configuring device properties, define a data configuration structure for different types of devices. In the case of a large n...
