Abstract. Proteus is a simulation software, can simulate analog circuit, digital circuit, microcomputer circuit and embedded system. Proteus software applied to the teaching of electric courses can not only improve the overall teaching effect, but also reduce the cost of laboratory construction, and promote the teaching reform of electric courses. Practice has shown that this method can better help students understand the electric courses, and greatly improve the students' interest and enthusiasm.
This paper gives a new design for Ethernet/IP Intelligent Communication Modules (EIICM). The new EIICM module not only acts as the network communication module for the PLCs to facilitate the communications between the PLCs and the remote network devices, but also it acts as the CPU of the built-in operation switch to perform the network topology monitoring and maintenance, IGMP Snooping, and switch managing and diagnosing. Furthermore, it acts as an Ethernet/IP and MB/TCP end device to provide implicit and explicit messaging services. In this paper, it focuses on the overall architecture, the functional design and some key techniques of new solution in EIICCM, such as "Structured Message Broker" pattern, "Management-self Adaptable" pattern, and device management method. It has given a new solution for the next generation of Ethernet module for industrial PLC.
Based on the structure and theory of opticalmechanical-electrical automatic ranging system of vehicles, paper has a discussion and research of the architecture and design of auto ranging system with risk estimation and decision making basing on embedded CPU. The solution of embedded system has got a good real-time performance and it can promote the data processing capability of the system. Paper mainly introduces the defects of SCM (Single Chip Micyoco) based ranging system and the hardware architecture, software architecture and some other key technology of the embedded system based ranging system, etc. It also introduces the solution of using two lidars light detection and ranging method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
