Cross-platform universal protocol analysis method, device and medium based on interpretive language

Abstract

The invention relates to a cross-platform universal protocol analysis method, device and medium based on an interpretive language, which comprises the following steps of: pre-recording a plurality ofstandard public protocols, respectively writing analysis scripts of the standard public protocols based on an interpretation script language, and taking source contents of the analysis script public protocols as input and output unified standard protocols; setting a script parsing engine, writing a script library into the script parsing engine, setting calling interfaces of various platforms, andthen distributing and setting the script parsing engine on each application node of the Internet of Things; when the equipment is accessed, identifying whether a communication protocol used by the equipment belongs to a pre-recorded standard public protocol or not; if yes, outputting a unified standard protocol through a script analysis engine; and if the script does not belong to the script library, writing a new analysis script through an interpretive script language, recording the new analysis script into the script library, and performing hot update on a script analysis engine.

Description

technical field [0001] The invention relates to a cross-platform general protocol analysis method, device and medium based on an interpreted language, and belongs to the technical field of the Internet of Things. Background technique [0002] In the field of Internet of Things applications, smart sensors are the core nodes. There are many types of smart sensors, and there is a lack of unified protocol standards at the industry or national level, resulting in incompatibility and universal processing when connecting sensors. In the prior art, the access of sensor equipment mainly includes the following solutions: [0003] 1) In the segmented field of the Internet of Things, the business is relatively concentrated, and downstream manufacturers are controllable. The platform adopts a limited exhaustive method to adapt to sensor access; [0004] 2) In the field of public IoT service platforms, because the sensors and manufacturers are uncontrollable, it is no longer possible to ...

AI Technical Summary

Problems solved by technology

[0004] 2) In the field of public IoT service platforms, because the sensors and manufacturers are uncontrollable, it is impossible to adopt the method of adapting the sensor protocol from the top to the bottom platform

[0006] For the above-mentioned existing technologies, the limited and exhaustive method is only applicable to scenarios with fixed sensor types. This method has high code redundancy and cannot be reused; protocol description using XML cannot be universally applicable to complex scenarios, and XML loading, Low reading and writing efficiency, high resource consumption, not suitable for lightweight sensor devices
