Research on the overall architecture of Internet of Things middleware for intelligent industrial parks

With the continuous development of the Internet of Things technology and the proposal of “Made in China 2025”, the construction of IoT application models for intelligent production lines, intelligent workshops, smart factories and other manufacturing industries has attracted more and more attention. In the smart industry, there are many types of devices connected to the Internet of Things, and the data format of the devices is not uniform. Therefore, when the upper layer application collects device data and manages the devices, it is necessary to introduce middleware to solve these problems. A service-oriented IoT middleware model is designed. This middleware is built on the background of the smart campus with the above characteristics. The middleware is responsible for realizing the information interaction between the front-end sensing device and the upper-layer application, sending the commands of the upper-layer application to the device to implement real-time management of the device and providing a heterogeneous intelligent device for accessing the Internet of Things application environment, an effective solution. And through an application example, the working principle and implementation of this middleware are further illustrated.
