Embodiment Construction

[0036] The present invention will be further elaborated below in combination with an implementation example of an energy-saving control solution based on the data service middleware platform. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. Such as Figure 4 As shown, the main working mechanism of this embodiment is: obtain the temperature data in the room and the user's current location in real time, and the external prediction system predicts the user's arrival time based on the historical trajectory data, and judges whether it is necessary to turn on or off the temperature control system based on the historical heating curve. Control the device and push messages to the Android APP at the same time.

[0037] 1. Device management module. The Android App involved in this implementation example, the smart switch of Nanjing Wulian, the DFRobot temperature and humidity sensor...

Abstract

The invention belongs to the technical field of Internet of Things, and specifically relates to an Internet of Things data service middleware system. The system mainly comprises a device management module, a protocol analysis module, a data interaction module, a database access interface, a data push subscription interface and an external system service packaging interface. An external sensor device sends data to the middleware system through a gateway. The device management module determines whether the used protocol is configured in a configuration file in the protocol analysis module according to the data packet. If the protocol is configured, a corresponding virtual entity is established for the sensor, and the data packet is sent to the protocol analysis module. The data packet is unpacked according to the corresponding protocol encapsulation class. The unpacked data enter the data interaction module for unified format conversion and enter a data queue to wait for processing. Three data interfaces are used for providing a database access operation, pushing data to a subscribed user system for a push service system, and transmitting the data to an external service system, wherein the data are as used as the source data of the external service system.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to an Internet of Things middleware system for providing data services. Background technique [0002] The core of the Internet of Things is the Internet, which is the acquisition, processing and interaction of information and data. Different from the Internet, the Internet of Things lacks widely adopted norms and standards such as HTTP and TCP / IP. Different equipment manufacturers will define their own data communication and analysis standards according to their own needs. However, the Internet of Things is a relatively open ecological environment, and the heterogeneity of devices and data has caused serious compatibility problems, which has caused great difficulties for the reuse and unification of application services. [0003] In order to shield the heterogeneity of devices, data, and protocols, it is necessary to provide a set of unified description, ...
