The present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
Examples
The application provides an Internet of things platform architecture based on a rule engine, which comprises an application layer, a system service layer, a network layer and an equipment layer which are sequentially arranged from top to bottom and are in communication connection. In order to deal with the compatibility problem that different Internet of things devices are connected into an Internet of things platform, a lightweight rule engine Drools is introduced into the Internet of things platform, a set of API (application programming interface) for processing logic services is independently provided in a service layer, a set of setting logic which can be customized by a user is designed, the user can customize different monitoring rules according to different scene requirements, and the Internet of things platform is suitable for various Internet of things devices.
As shown in fig. 1, the present application mainly embodies the idea of layering and classification for the lowest device layer. Firstly, a receiving node is set to receive the information collected by the sensor, and a gateway node is needed to be set to collect the information of a plurality of sensor nodes. As gateway equipment, the gateway of the Internet of things can realize the combination of a sensor network and a communication network and the protocol conversion between different types of protocols. The gateway plays a very important role in the future internet of things, and becomes a link for connecting the sensor network and the traditional communication network. In this embodiment, the sensor includes a temperature sensor and a humidity sensor.
In this embodiment, the network layer uses MQTT communication protocol. And the network layer is responsible for subscribing and publishing the data collected by the equipment layer at the MQTT cloud. On one hand, any device can be uploaded to the MQTT server in a place with signals as long as the device is connected to WIFI, and corresponding data can be obtained and uploaded to an upper system service layer as long as the device subscribes to a corresponding theme.
The system business layer comprises a rule engine module, a database rule event table, a database gateway table, a database sensor table and an API (application programming interface) for processing logic business. The rule engine module comprises a data management module, a logic management module, a rule control module and an event trigger module, and processes the logic rules through the Reta algorithm of the rule engine technology. The system service layer mainly gathers monitoring data input by the sensor and analyzes and processes the data. The layer comprises a plurality of processing modules and is the core of the service function of the whole platform. The cloud subscription data processing method comprises the steps of firstly screening and classifying data subscribed by a cloud and storing the data in different database tables, and additionally, processing real-time data, which needs to be supported by a rule engine module.
The application layer comprises a monitoring platform control end, the monitoring platform control end comprises a rule event setting module associated with the database rule data table, an equipment registration module, an equipment data module and a data monitoring and alarming module, and the equipment registration module is associated with the equipment layer. The application layer mainly provides an interface for data interaction with a user. On one hand, a user registers equipment and sets corresponding rules through the Internet of things platform, and on the other hand, the user can monitor equipment data to perform event alarm. Besides, the functions of user login, user deletion, user authority setting and the like can be performed on the user role function module.
In this embodiment, the internet of things platform selects JBoss Drools as the business rule engine, mainly because Drools has high flexibility, the rule making language is also very friendly to non-technical personnel, and a user can efficiently make the needed rules. JBoss Drools is an open source business rules engine. Drools sets rule logic through a scripting language, the rule file supports XML and DRL file formats, and non-developers can quickly and conveniently set the rule logic in an XML application scene. Additionally the JBoss Drools rule file supports the injection of JAVA expressions.
The rule engine technology has the greatest advantage of realizing the separation between the business logic rules and the application modules, so that the system has high flexibility and maintainability. Aiming at the Internet of things platform deployed in a large range, the corresponding rule engine also needs to have the capacity of processing mass information, the capacity of processing data in real time and the capacity of multiplexing similar data. The rule engine module mainly realizes the following functional characteristics:
and (3) expandability: massive sensor data need to be input into the large-scale deployed Internet of things monitoring equipment, so that the rule engine module used by the platform needs to extract parts with the same data format of different types of sensor data, unified processing is carried out in the rule logic processing stage, and the differences of the sensor data are distinguished in the application layer part;
real-time processing: the rule engine is required to continuously interact with the database in the processing stage, so that a core data part recorded by the sensor is required to be extracted in real time when business rule logic is formulated, the formulated rule is simplified when the rule is formulated, and the influence of too complicated rule formulation on the processing speed is prevented;
and (3) event cycle processing: the processing result of a certain rule can become the input event of the next rule;
dynamically configurable: with the increase of user-defined monitoring equipment and business logic, the rule service in the rule engine is required to be continuously modified; the change must be dynamically realized, when the equipment and the service are changed, the rule file can immediately complete the update of the rule file, the normal operation of the system cannot be influenced, and the system can also immediately update the newly established rule file after the update is completed.
