A Real-Time Monitoring and Certification System for Logistics

Monitoring the goods’ statue and certificating the identity of the recipient is becoming a big issue in logistics system. In this paper, we propose a system which contains an embedded terminal and a cloud services platform to monitor the real-time statue of the goods. The embedded terminal uses the GPS satellite signal and the nearby base stations to determine the location of the goods. Besides, acceleration sensor and the video capture unit are adopted to monitor the integrity of the goods. Simultaneously, the cloud services platform can identify the recipient, and provide the customers with the query interface. The two parts of the system can communicates with each other in wireless channel through the communication unit.

Design of Portable Educational Technology Terminal Based on Embedded System

In current education realm, the new technology terminal is essential for modern educational method. Thus, the embedded technology is focused and utilized to improve the level of education technology. In this paper, a kind of embedded terminal is designed for experimental class application, which is based on AVR-mega48, and the LCD, the standard keyboard, the nRF2401 wireless modules are integrated into the system. The whole system operates under the control of UC/OS-II system, which provides an excellent software platform for the future development of other modules.

On an Embedded Terminal Application of Cyber Source Allocation Scheme

This paper expounds the rational allocation of the limited network bandwidth resources in between the embedded terminal application, and puts forward a kind of embedded terminal application of cyber source distribution protocol. According to the application characteristics, classify network packets; combined with the available bandwidth real-time detection, add different delay time for each type of data packet; according to the size of delay, schedule data packet. The protocol is applied to the actual IP set-top box, at the same time it is running HTTP streaming media applications and downloads the FTP application environment, to give priority to ensuring the application of streaming media playback smooth. The experimental results show that, the protocol in the application environment can give priority to the needs of users about application of high bandwidth network, and achieve a reasonable distribution of cyber source in embedded terminal.

Design and Application of Embedded Intelligent Power Consumption Terminal

ntelligent power consumption system is an important mean to improve the energy efficiency. An embedded terminal was designed in the system, which can achieve intelligent control and management for devices, and reduce power and energy consumption. The terminal in the system was designed and implemented based on ARM platform, using B/S structure to communicate with the remote server through Internet. It has several wired and wireless communication interfaces, which can be connected with various electric equipments. For extensibility, the software of the terminal uses a hierarchical and modular approach which includes communication layer, device layer, interface layer and intelligent power consumption layer. Meanwhile, the communication protocol and the unified interface design in the terminal make sure that the terminal can interact with the remote server reliably and timely. Through experiments in the demonstration operation region, it concludes that the terminals work stable and reliable, and equipment intelligent control and management are fulfilled. The system has many advantages such as modularity and scalability, which can be widely used in many fields like smart grid and smart home, etc.
