Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. 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
As shown in fig. 1, the application provides an internet of things gateway based on a lightweight rule engine, and a bottom layer is accessed to some commonly used sensor devices, such as a temperature sensor and a humidity sensor, and through the internet of things gateway, a user can remotely acquire and control state information of the sensor devices. The internet of things gateway comprises a storage module, a gateway control module, a rule engine module and a gateway configuration module which are connected in sequence.
The gateway control module comprises an input module and an output module, is responsible for data input and output of a serial port and a network port of the gateway, and controls external output of the gateway, for example, the gateway reads or controls various states of the modbus equipment by using the serial port, and stores the state values in a storage module of the gateway. The gateway control module is also connected with the communication module and is connected with the cloud platform through the communication module.
The gateway configuration module comprises different actual scene rules required by the user, converts the actual scene rules required by the user into texts, and stores the texts in an xml file format.
The rule engine module is responsible for the logic judgment part of the gateway. In the process of applying the rule engine to the actual internet of things gateway, the real-time state information or the real-time data information of the sensor equipment is used as a fact item of the rule engine module fact set, and the business rule of the application scene created by the user is used as a rule item of the rule engine module rule set. The fact set is a set of fact items in the system and corresponds to state information of a bottom sensor of the gateway of the Internet of things; the rule set is a set of rule entries in the system, and corresponds to business rules defined by the gateway user of the internet of things. A fact represents the state value of each fact variable, typically in the form of "… … is (or is equal to) … …". A rule consists of a condition part and an action part, typically in the form of "if … …, then … …", the condition part being "if … …" and the action part being "then … …". The condition part and the action part can both contain one or more condition elements, and a plurality of condition elements are connected by using 'and' OR 'or' to express the logical relationship between the condition elements. The value of each condition element is a Boolean variable, the condition part is a logic combination of a plurality of Boolean variable expressions, and the action of the action part is executed only when the logic result of the condition part is true. Each condition element is associated with a fact variable, a rule comprising a plurality of condition elements is associated with a plurality of fact variables, and the one or more associated fact variables are used as values of the 'associated fact' attribute of the rule, namely the value of the 'associated fact' attribute is a set of one or more fact variables associated with the rule.
The rule engine module comprises an information acquisition module and a rule matching module which are connected with each other. The information acquisition module comprises a fact acquisition module and a rule acquisition module. Firstly, a rule acquisition module acquires an actual scene rule of a gateway configuration module as a rule set, and a fact acquisition module acquires state information of related sensor equipment as a fact subset according to the actual scene rule; and then the rule matching module matches the rule set with the fact subset according to a matching algorithm, if the actual scene rule of the gateway configuration module is matched, the corresponding control information is sent to the gateway control module, and then the matching process is returned to continue matching.
