  • ASR M08-B资料

    ASR M08-B设置软件 V3.2  arduino 2560+ASRM08-B测试程序  arduino UNO+ASRM08-B测试程序语音控制台灯电路图及C51源码(不带校验码) 继电器模块设置。   ASR M08-B是一款语音识别模块。首先对模块添加一些关键字,对着该模块说出关键字,串口会返回三位的数,如果是返回特定的三位数字,还会引起ASR M08-B的相关引脚电平的变化。【测试】①打开“ASR M08-B设置软件 V3.2.exe”。②选择“串口号”、“打开串口”、点选“十六进制显示”。③将USB转串口模块连接到语音识别模块上。接线方法如下:语音模块TXD --> USB模块RXD语音模块RXD --> USB模块TXD语音模块GND --> USB模块GND语音模块3V3 --> USB模块3V3(此端为3.3V电源供电端。)④将模块的开关拨到“A”端,最好再按一次上面的大按钮(按一次即可,为了确保模块工作在正确的模式)。⑤对着模块说“开灯”、“关灯”模块会返回“0B”、“0A”,表示正常(注意:0B对应返回值010,0B对应返回值010,返回是16进制显示的嘛,设置的时候是10进制设置的)。

  • 用C51实现无功补偿中电容组循环投切的算法

    介绍了用单片机C 语言实现无功补偿中电容组循环投切的基本原理和算法,并举例说明。关键词:循环投切;C51;无功补偿中图分类号: TM76 文献标识码: BAbstract: This paper introduces the aplication of C51 in the controlling of capacitorsuits cycle powered to be on and off in reactive compensation.it illustrate thefondamental principle and algorithm with example.Key words: cycle powered to be on and off; C51; reactive compensation 为提高功率因数,往往采用补偿电容的方法来实现。而电容器的容量是由实时功率因数与标准值进行比较来决定的,实时功率因数小于标准值时,需投入电容组,实时功率因数大于标准值时,则需切除电容组。投切方式的不合理,会对电容器造成损坏,现有的控制器多采用“顺序投切”方式,在这种投切方式下排序在前的电容器组,先投后切;而后面的却后投先切。这不仅使处于前面的电容组经常处于运行状态,积累热量不易散失,影响其使用寿命,而且使后面的投切开关经常动作,同样减少寿命。合理的投切方式应为“循环投切”。这种投切方式使先投入的运行的电容组先退出,后投的后切除,从而使各组电容及投切开关使用机率均等,降低了电容组的平均运行温度,减少了投切开关的动作次数,延长了其使用寿命。

    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.
