Abstract

The invention discloses a CPS-based Internet of Things equipment data and capability model design method. The method comprises the following steps of defining parameters of different types of facilities and equipment through a unified standard; designing object templates of the facilities and the equipment according to the management attributes of the facilities and the equipment; designing an alarm model; designing a control model of the facilities and the equipment according to the actual operation capability of the facilities and the equipment; and designing a relationship model of businessrelationships or linkage rules among different facilities and equipment. According to the method, the model definition method provided by the invention fully describes the characteristics and capabilities of the facilities and equipment; through a visual management system mode, the facility equipment can be configured and described quickly and conveniently; the design method can be expanded as required and secondarily modified as required, and secondary expansion and modification applying the method are free of any development cost; and the method has certain replicability, and has practicalvalue in the industries of industrial automation and building intellectualization.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a design method of a data and capability model of an Internet of Things device based on CPS. Background technique [0002] With the vigorous development of the Internet of Things, the application fields of the Internet of Things involve all aspects, effectively promoting the intelligent development of the industry, but it is also accompanied by fragmented applications, inconsistent development standards, high development thresholds, and high implementation costs. [0003] Even for the same facility and equipment, due to different brands, specifications and models, its collection parameters, alarm parameters, setting parameters, and equipment functions may be different. However, for a unified IoT platform, comprehensive and effective centralized management is required. According to the traditional development and design mode, one by one docking and unified managemen...
