[Embeded Linux] www DL : 0: 基于s5pc100-A8板的智能仓储物联系统,1. M0作为前端信息采集器，通过温湿度、光感等模块实时采集节点所在仓库的环境数据，通过RFID射频刷卡模拟货物出入库，将采集到的数据和货物存储信息通过ZIGBEE无线传输给A8主控板进行数据分析。 2. A8是整个系统的逻辑处理核心，采用多线程架构，线程间使用全局变量、互斥锁、条件变量实现线程同步、互斥、唤醒等动作；分析M0发送来的数据，唤醒相应线程进行短信报警、摄像头抓拍、蜂鸣器、LED灯光报警、出入库等动作，并将数据存入数据库中； 3. A8架设了BOA服务器，可以通过网页和CGI程序与A8主程序进行数据交互，实现仓库数据信息网页显示，网页端可经A8向M0发送指令实现远程控制M0动作；通过网页客户端可以控制摄像头实时监控或拍照存档。-Based s5pc100-A8 board intelligent storage system of Things, 1. M0 information collector as a front end, by the temperature and humidity, light and other real-time acquisition module node where the data warehouse environment, RFID radio frequency card through simulation goods out of storage, will be collected data and information via cargo storage ZIGBEE wireless transmission to the A8 MPU data analysis. 2. A8 is the logical processing core of the system, multi-threaded architecture, the threads using a global variable, mutex, condition variables to achieve thread synchronization, mutual exclusion, wake-up action M0 transmitted data analysis, Wake corresponding thread SMS alarm, camera capture, buzzer, LED light alarm, out of storage and other actions, and the data stored in the 3. A8 BOA set up a server, you can exchange data through Web pages and CGI programs and A8 main achieve page displays data warehouse, web end the A8 to send commands M0 M0 remote control operation it can
