Access service system for unified access equipment

Abstract

The invention discloses an access service system for unified access equipment, and the system comprises an equipment layer, a unified access layer, an abstract service layer, and an application layer. The equipment layer comprises a plurality of sensing devices which respectively have an independent data collection mode and enable collection data to be gathered in the unified access layer. The unified access layer comprises an equipment communication module, an equipment function abstract module, a data abstract module, and a protocol conversion module. The abstract service layer is used for receiving the data transmitted by the unified access layer, carrying out analysis, processing and storage, and uploading the data to the application layer. The unified access layer carries out timing query of an equipment control instruction sent by the application layer, and transmitting the equipment control instruction to the corresponding sensing device if the equipment control instruction is used for controlling the sensing device in the network. The system achieves the separation of equipment access and an application system, and improves the universality of equipment access.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to an access service system for unified access devices. Background technique [0002] With the rapid development of the Internet of Things technology, it realizes the connection between things and things, people and things, and then realizes informatization, remote management control and intelligent network. In existing industrial applications, a large number of sensor devices are required to perceive the surrounding environment. Different applications require different hardware devices, and various hardware devices have different interfaces. Therefore, there are many devices and interfaces, and the unified access of devices has become an urgent problem to be solved in industrial applications. [0003] In traditional industries, various applications are independent of each other, data does not interfere with each other, and there is no need for a unified ...

Problems solved by technology

Device access is not separated from the application system, forming a corresponding relationship. However, when the connected device cannot meet the needs of the application system, it is difficult to expand the device, and the scalability of device access is very poor.

When a new device function is to be integrated in an application system, the structure of the entire application system will change accordingly, seriously affecting the stability of the system
