DS1820 数字温度计提供9 位温度读数,指示器件的温度 信息经过单线接口送入DS1820 或从DS1820 送出因此从中央处理器到DS1820 仅需连接一条 线和地读写和完成温度变换所需的电源可以由数据线本身提供而不需要外部电源 因为每一个DS1820 有唯一的系列号silicon serial number 因此多个DS1820 可以存在 于同一条单线总线上这允许在许多不同的地方放置温度灵敏器件此特性的应用范围包括HVAC 环境控制建筑物设备或机械内的温度检测以及过程监视和控制中的温度检测

Secure Programming Cookbook for C and C++ is an important new resource for developers serious about writing secure code for Unix(including Linux) and Windows environments. This essential code companion covers a wide range of topics, including safe initialization, access control, input validation, symmetric and public key cryptography, cryptographic hashes and MACs, authentication and key exchange, PKI, random numbers, and anti-tampering.

Implemented BFS, DFS and A* To compile this project, use the following command: g++ -o search main.cpp Then you can run it: ./search The input is loaded from a input file in.txt Here is the format of the input file: The first line of the input file shoud contain two chars indicate the source and destination city for breadth first and depth first algorithm. The second line of input file shoud be an integer m indicate the number of connections for the map. Following m lines describe the map, each line represents to one connection in this form: dist city1 city2, which means there is a connection between city1 and city2 with the distance dist. The following input are for A* The following line contains two chars indicate the source and destination city for A* algorithm. Then there is an integer h indicate the number of heuristic. The following h lines is in the form: city dist which means the straight-line distance from the city to B is dist.

* CONSTRAINTS * This module does not handle data which is considered out of range by the * application(i.e. fixed constants which represent error condition) * * Maximum weight value must be limited to 128 to prevent an overflow * condition during the calculation. * * The internal data type must be large enough to handle the calculations. * The maximum possible internal value * = Max Input Value * (weight - 1) + Max Input Value * If a maximum weight of 128 is used, the internal data type should be 2 * times the size of the input data type.

本程序分为界面和控制器核心两部分 一、界面部分功能主要有： （1）显示控制器核心数据和参数 （2）与用户交互，可以调节初始输入温度值，并将温度变化率清零以便进行新一轮的模拟。 界面使用了定时器。开启模拟时候，每隔一秒，触发一次计时器消息，完成下列工作： 1. 将界面上的当前温度映射为模糊控制器的输入温度 2. 输出当前温度，当前温度变化率 3. 调用模糊控制，得到控制器输出值，将其乘以m_fFuelEffect (燃料输出对温度变化率的影响率，目前设置为0.3)，得到变化率的变化，加到当前温度变化率上，得到新的变化率。 4. 更新变化率，更新温度。将结果映射到界面上。 5. 记录相关数据并以图形、数字方式输出。 二、控制器核心用到的类有 （1）Rule_Func_Single 将简单的函数包装成类，方便后面使用。实现了 NB, NS, ZO, PS, PB 等梯形函数，以及常值函数。 （2）Grading_Func 继承自Rule_Func_Single类，比基类增加一个输入参数，指明梯形函数属于Input, Delta或者Output 。 （3）Rule_Function 将两个Grading_Func结合在一起，进行模糊与或模糊或等模糊逻辑操作，并输出结果。
