A method and system for processing data of an Internet of Things hardware gateway based on a single chip microcomputer

Abstract

The present invention provides a data processing method and system for an Internet of Things hardware gateway based on a single-chip microcomputer. By establishing a mapping table and a data table for data and equipment, a flexible and easy-to-configure data interaction mode is realized based on the mapping table and data table, and the data interaction process is realized. The configuration personnel only need to configure the content of the report message configuration table according to the requirements, or change the corresponding relationship between the data table and the mapping table, and then easily change the data interaction mode of the single chip microcomputer, avoiding the data interaction due to changes in data requirements. The program needs to be upgraded; the data is stored in units of time, extending the service life of the memory.

Description

technical field [0001] The invention relates to the field of single-chip microcomputer data processing, in particular to a single-chip microcomputer-based Internet of Things hardware gateway data processing method and system. Background technique [0002] Single-chip microcomputer (Single-Chip Microcomputer) is an integrated circuit chip, which uses VLSI technology to integrate a central processing unit CPU with data processing capabilities, random access memory RAM, read-only memory ROM, various I / O ports and interrupts. System, timer / counter and other functional circuits are integrated into a silicon chip to form a small and complete microcomputer system, which has a wide range of applications in the field of industrial control. In particular, the single-chip microcomputer can be used in the gateway of the Internet of Things to realize the protocol conversion between the perception network and the communication network, and between different types of perception networks.

Problems solved by technology

In particular, the single-chip microcomputer can be used in the gateway of the Internet of Things to realize the protocol conversion between the perception network and the communication network, and between different types of perception networks. Correspondingly, the single-chip microcomputer needs to process the data transmitted to the upper layer or to the lower layer, and The single-chip microcomputer used in the gateway of the Internet of Things needs to process a large amount of data, and the performance of the current single-chip microcomputer is not good in data processing

[0003] The specific performance is: the data storage and retrieval performance of the current single-chip microcomputer is not good. At present, the common practice is to store the data in the Flash memory, and the number of data reads and writes of the Flash memory is limited. When a large amount of data is involved, it is easy to have the problem of limited service life of the Flash memory; in addition, the current retrieval of massive data needs to traverse all the data, which is time-consuming and labor-intensive, and the retrieval efficiency is low

[0004] Not only that, the current data interaction mode between the communication interfaces of the single-chip microcomputer is set by the designer in advance through the coding program. If the data interaction mode needs to be changed, the program needs to be re-modified, resulting in high operation and maintenance costs of the single-chip microcomputer.
