规模大通过的智能设备像智能手机一样为个人使用打开了一个机会来确定个人通过其智能设备的身份。本文旨在实现非常简单的通过使用指针式复示器板，如与使用蓝牙技术，几乎在每一个智能设备中可用的智能设备进行交互的 Arduino 的设备进行身份验证的用户的访问控制技术。通过试验讨论了实现过程。作为一种方法论的安全通信，手机的应用程序使用密码保护。一些可能的应用领域被讨论拟议的方法可用于启用相应的服务。新奇的这项工作是为用户的访问在有担保的受保护地方提供一个简单、 低成本的解决方案。进一步，拟议的身份验证机制是直观，需要最小的努力。

jmsn是一个完整的JAVA应用程序，下载解压后可以直接运行，运行的界面跟微软的MSN Messenger很类似，包括操作上都非常一致，如果你的操作系统是Linux或者其他那都可以直接用它来替代微软的程序。另外一个是msnm-lib，这个就是我们今天要介绍的API，它仅仅是一个开发包，在jmsn组件中已经包含了这个包。 -jmsn is a complete Java application that can be downloaded directly unpacked run, run interface with Microsoft"s MSN Messenger is very similar, including the operation are very consistent, if you are running Linux or other it can be directly used it to replace Microsoft"s procedures. Another one is msnm-lib, today we are introduced to the API, it is merely a development kits, in jmsn already contains components of the package.

】　本文主要讨论了Modbus 通信协议的R TU 帧格式中常用的错误校验方法,即循环冗余校验法( CRC) 。 提出了Modbus 协议反转CRC 校验的方法,推导了反转CRC 校验快速计算表格,并用C 语言实现了基于快速查 表算法的循环冗余校验程序。-In this paper, we mainly discuss the Modbus communication protocol R TU frame format commonly used in error checking methods, namely, Cyclic Redundancy Check Code (CRC). Modbus protocol proposed inversion method CRC checksum, CRC checksum is derived fast computing inversion table, and C language to achieve a quick look-up table algorithm based on cyclic redundancy check procedure.

虽然Windows下可视化开发工具如VC、Delphi、C＋＋ Builder等都有专用的定时器控件Timer，而且使用很方便，可以实现一定的定时功能，但最小计时精度仅为55ms，且定时器消息在多任务操作系统中的优先级很低，不能得到及时响应，往往不能满足实时控制环境下的应用。不过Microsoft公司在Win32 API函数库中已经为用户提供了一组用于高精度计时的底层函数，如果用户使用得当，计时精度可到1ms。这个计时精度、对于一般的实时系统控制完全可以满足要求。现将由C＋＋ Builder 4.0提供的重新封装后的一组与时间相关的主要接口函数（函数名、参数、功能与Win32 API基本相同）说明如下： -visual development tools such as Visual C++, Delphi, C++ Builder and others all have dedicated Timer timer control, but it is convenient. can achieve a timing function, but only the minimum time of 55 ms accuracy. Timer news and multi-task operating system in the low priority that is not to respond in a timely manner, often fail to meet the real-time control environment applications. However, Microsoft Corporation in the Win32 API function has been to provide the user with a group for high-precision the bottom was a time function, if the user is properly utilized, time accuracy can be a ms. Accuracy this time, and for most of the real-time control system can meet the requirements.
