Description: 基于DS18B20的温度测量装置电图如图2所示：温度传感器DS18B20将被测环境温度转化成带符号的数字信号（以十六位补码形式,占两个字节）,传感器可置于离装置150米以内的任何地方,输出脚I/O直接与单片机的P1.1相连,R1为上拉电阻,传感器采用外部电源供电。89C2051是整个装置的控制核心,89C2051内带1K字节的FlashROM,用户程序存放在这里。显示器模块由四位一体的共阳数码管和4个9012组成。系统程序分传感器控制程序和显示器程序两部分,传感器控制程序是按照DS18B20的通信协议编制。系统的工作是在程序控制下,完成对传感器的读写和对温度的显示。

Description: 89C2051在这里的基本作用是检测外接的多路有线报警传感器的报警电平信号，并转化成一一对应的“COMSMSXX”指令，最后从串口以9600BIT/S、8、N、1的格式发送给JB35/JB35G，触发JB35/JB35G“报警设置（2）”中的报警短信。由于89C2051口线的限制，我们只扩展了12路外接传感器并口输入口，如果用户需要把20路都转化成并口输入口，那就要用更多口线的单片机来实现，如89C51等。-89C2051 here the basic role is to detect external road many wired alarm sensor alarm level signal, and one-to-one into the " COMSMSXX" command, and finally from the serial port to 9600BIT/S, 8, N, 1 format sent to JB35/JB35G, trigger JB35/JB35G " alarm settings (2)" in the alarm message. 89C2051 mouth lines because of the restrictions, we can only extend the road 12 parallel port external sensor input, if users need to put all 20 into a parallel road input, then I use more lines to achieve single-chip microcomputer, such as 89C51, etc..

Description: 我单位有一无人值守的机房位于一高山山顶上，上山的路是600多级的台阶。因通信需要，有时要开关某些机器设备，操作上虽然简单，但要工作人员花10多分钟爬一趟山，不仅辛苦，而且拖延了时间。为解决此问题，本人利用89C2051单片机，设计了一遥控开关，在山下机房便可对山顶上的设备进行开关机-My unit is an unattended computer room is located in a mountain top of the hill, the road up the mountain is more than 600 steps. Due to their communication needs, sometimes you want to switch certain machinery and equipment operation, although simple, but the staff spent more than 10 minutes to climb a trip to Mountain not only difficult, but also delay the time. To solve this problem, I use 89C2051 microcontroller design of a remote control switch, can switch on the top of the hill on the equipment room at the foot of the mountain
