Serial port communication protocol automatic adaptation middleware

Abstract

The invention discloses serial port communication protocol automatic adaptation middleware which is applied to the communication process between serial port equipment and an equipment cloud platform and structurally comprises a relational database provided with a description protocol structure, a cache database for storing a protocol structure and an analysis module for analyzing a user-defined serial port protocol. User-defined serial port data protocols in different formats, such as a fixed-length fixed-sequence format, a fixed-lengths variable-sequence format, a variable-length fixed-sequence format, a fixed length array and an unfixed-length array, are analyzed; inputting the protocol configuration information into a relational database and synchronizing the protocol configuration information to a cache database; and the analysis module analyzes the serial port data uploaded by the equipment through the protocol configuration information in the cache database, uniformly converts the serial port data into data in a JSON format and uploads the data to the platform for processing, so that the development and maintenance cost of accessing the serial port equipment into the cloud platform is reduced, and the access speed is increased.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an automatic adaptation middleware of a serial port communication protocol. Background technique [0002] With the large-scale popularization and blowout development of the Internet of Things, more and more different types of devices are connected to the network, among which serial communication devices account for half of the country. The serial port is a common communication interface for instrumentation equipment. The serial port communication protocol is used to obtain data from remote acquisition equipment. Each bit of the information byte is transmitted in a fixed order, which has the advantages of strong anti-interference ability, low cost and long transmission distance. The data collected from the serial port is sent to the cloud through WI-FI or GPRS, which is a common way for traditional devices to go to the cloud. [0003] The serial port communication protocol ...

AI Technical Summary

Problems solved by technology

Since different types of serial device manufacturers have different communication protocol formats, the platform cannot uniformly analyze the user layer protocol. It is necessary to identify the device type and use the corresponding analysis method to process the data packet, which reduces the speed of device access to the platform and improves The difficulty of platform data processing and maintenance
