At last , after introducing the design of an atmel 89c51 single chip system and some circuit , we have an experiment of active vibration control of cantilever with the fuzzy controller based on the general membership function we designed , and the cantilever beam is equipped with piezoelectric sensors and actuators 以装有压电传感器和驱动器的悬臂梁的应变为控制对象，以所设计的单片机系统作为控制器，采用具有广义隶属函数的模糊控制算法进行了悬臂梁主动减振控制实验。
By reason of distinction between the jvm instruction set and the classic ones , there are many problems in architecture , object - orientation implementation , interface between hardware and software , operating system of java chip system . existing java chip systems have many flaws 由于java虚拟机指令系统和经典微处理器指令系统有很大区别， java芯片系统在硬件体系结构、面向对象的实现机制、软硬件接口和操作系统结构等方面都面临许多新的技术问题和设计难度，以致已有的java芯片系统都存在许多需要改进的不足之处。
In order to solute these disadvantages , we find that we can apply the gsm common network to transport data . that is , we use gsm modem that can support short message service to transport alarm information connecting with the single chip system through standard rs232 interface . we can make the data transported wireless , and the monitor terminal is not only pc , but also mobile telephone or other mobile terminals 针对这种情况，我们可以利用gsm公共网进行数据传输的方法，即在传统的单片机系统中利用支持短消息业务的gsm引擎模块发送报警信息，通过标准的rs232接口结合已有的单片机系统，利用现有的900m或1800m的gsm网络，实现数据的无线传输，而监控终端也不再仅局限于pc机，也可以是移动电话或其他移动终端。
Customer can visit the server conveniently through ie browser but not make up by oneself upper machine software , and can conveniently , swiftly look over the single - chip system function situation and send out corresponding control instructions , really achieve the goal of monitoring and control long - distantly 客户可以用ie浏览器而不用自编上位机软件就可以方便地访问服务器，可在任何可以上网的地方，方便、快捷地查看单片机系统的运行情况并对其发出相应的控制指令，真正达到远程监测与控制的目的。
This paper introduces the background of the development of small - sized automatic weather station , the concept of embedded type system , summarizes the requirements and function designs of the system , maps out a general frame , and carries out a hardware circuit theory design to the single chip system on the basis of real - time data collection system function 介绍了小型自动气象站的发展背景、嵌入式系统概念，综合论述了系统要求和功能设计，并给出整体架构；依据实时数据采集系统的功能，对单片机系统进行了硬件电路原理的设计。
To overcome these drawbacks , we study the crucial technologies in java chip system comprehensively in above fields and present je - java chip system which is suitable for the non - pc internet accessing devices . the measurement declares that the performance of je - java chip system is close to the similar system 针对这些不足，在对java虚拟机指令系统、应用程序和java芯片操作系统等进行深入分析和深刻理解的基础上，文中提出了一个用于非pc类internet访问设备的je - java芯片系统。
