But,the drawbacks of Shewhart's control chart is that when the control chart shows abnormal,it cannot tell us what and where is the assignable cause,i.e.it cannot diagnose the abnormalityof the process.In 1982,Prof.Gongxu Zhang proposed the diagnosis theory with two kinds ofquality,solved the diagnosis problem of assignable cause,thus opened a new direction ofstatistical diagnosis theory and developed the theory of SPC into a new stage ofSPCD(Statistical Process Control and Diagnosis).The multi-operation and multi-index system exists everywhere,in general,nearly all theproduction lines of factories belong to this system.

但休哈特控制图的缺点是，当控制图显示异常时，它不能告知是何原因、何处发生了异常，即不能诊断。1982年，我国著名质量管理专家张公绪教授提出两种质量诊断理论，解决了对异常因素的诊断问题，开辟了统计诊断理论的新方向，将质量控制推向了一个新的发展阶段——统计过程控制与诊断阶段。

The system can automatically supervise changes of temperature and humidity for the grain depot,compare with the preset parameter of temperature and humidity,and drive the correlative power equipment in order to keep temperature and humidity in stated ranges.The CAN bus technology is used in the distant measurement and control system,which improves the reliability of system.

可以利用CAN总线解决这些问题，它是一种面向工业控制的现场总线，集数字通信、智能仪表、微机技术及网络技术于一身，突破了以往"点对点"式的模拟——数字控制的限制，完全实现了对控制系统的分散控制，便于集中管理[1]。

Currently some different video transmission scehmes have been proposed, such as source-based adaptive rate control, receiver-based simulcast and layered multicast, but these schemes basically follow the traditional network design principles and take end-to-end congestion control and error control mechanisms without the participation of network intermediate nodes, making a series of problems such as session management difficulty, congestion control blindness, feedback explosion, and the difficulty in achieving fairness among different users.

目前对于网络视频传输已出现了各种不同的解决方案，如基于源的自适应速率控制方案和基于接收端的联播、分层多播等视频传输机制，但这些方案基本上都遵循网络设计的传统原则，采取基于端到端的拥塞控制和差错控制机制，而没有网络节点的参与，从而导致会话管理困难、拥塞控制盲目、反馈爆炸等一系列问题，而且难以在用户之间达成公平。
