Research Of The Internet Of Things Experiment Platform Based On Loongson Platform

In recent years,with the gradual development and widespread application of related technologies of the Internet of Things,more and more enterprises,research institutes and universities have devoted a lot of resources and energy to the research field of Internet of Things technology,therefore,Internet of Things education has become an urgent need,and thus teaching experiments related to the Internet of Things are also receiving great attention.The Internet of things is the integration and innovation of multiple technologies such as embedded systems and wireless technologies.Therefore,the simple embedded experimental platform and software experimental platform of many universities can no longer satisfy the students' professional learning of comprehensive IoT.On the other hand,with the continuous development of the Internet and information technology,the problem of network and information security has become even more prominent.The root cause lies in the fact that China's information technology is controlled by others.The general-purpose processor is the basic component of the information industry and is the core device of electronic devices.Development is related to the destiny of the country and national security.It is where the country's core interests lie.Since 2001,Loongson Technology has introduced a series of domestically-controlled embedded CPUs,but have not been well marketed.Based on the above two points,it is of great significance to develop a practical and scalable Internet of Things experiment platform based on a domestic platform.This article studies and designs a kind of internet of things experiment platform based on the domestic Loongson platform.The experimental platform includes two parts: a safe and reliable upper computer based on Loongson 3B1500 multi-core processor and a wireless network node lower computer based on Loongson 1C300 single-core processor.The use of TI CC2530 wireless module to achieve sensor wireless ZigBee networking;the use of open source Qt framework and its extension plug-in design of the host computer visual monitoring management software and IDE editing tools.In addition,according to the Internet of Things,embedded related professional curriculum content for the design of experimental projects.The experiment platform adopts a self-developed Loongson processor based on China,based on the standard MIPS architecture and Linux general operating system,with high-performance,autonomous controllable,and system open.The experimental platform from the bottom processor chip to the system software are independently developed or transplanted by China,and according to the relevant professional teaching curriculum needs to be streamlined and compiled,not only can meet the normal teaching needs,rich interface and open source system can also give students more.The broad space for thinking and development can also enable domestic self-CPU to be widely promoted.
