本系统以AT89S52单片机为核心部件,外加温度采集电路、及显示电路和越限报警等电路。采用单总线型数字式的温度传感器DS18B20,使系统具有测温误差小、分辨率高、抗干扰能力强,动态显示的方式等特点。本设计既可以对当前温度进行检测又可以对温度进行数码显示,两位整数两位小数的显示方式具有更高的显示精度,若超越极限温度则触发蜂鸣器报警。利用功能强大的Keil和具有互动电路仿真的Proteus进行程序的编写和仿真。-The system AT89S52 microcontroller as its core components, plus the temperature acquisition circuit, and display circuitry, and the more limited alarm circuits. Single bus-type digital temperature sensor DS18B20, the system has a temperature measurement error of the small, high resolution, anti-interference ability, dynamic show the way and so on. This design not only can detect the current temperature can also right temperature digital display, two integers with two decimal places are displayed to show a higher precision, if the temperature is beyond the limits of buzzer alarm is triggered. Keil and the use of powerful interactive circuit simulation of the Proteus programming the preparation and simulation.

简单的功能介绍:本软件是由,三块模块组成。一个是打字练习,一个是打字计时,一个是音乐练习。本软件解决了打字练习途中的估噪无味,提升练习效果。本游戏有4个等级,可以根据情况来选择。这个软件还改进了,判断你是否打字失败功能。如果,打字失败,还可以从来,亦可退出。打字计时,为你打字计时间,提高效率。同时,电子琴音乐,为你在无聊时,增添色彩,可以练习歌谱,提高兴趣。-Simple, functional description: This software is, three modules. 1 is a typing exercise, one is typing time, a music practice. The software solves the assessed noise typing practice tasteless way to improve practice effect. This game has four levels, you can choose depending on the circumstances. The software also improved, to determine whether you have failed typing feature. If, typing fails, you can never can quit. Typing time for your time typing dollars and improve efficiency. At the same time, organ music, for when you" re bored, add color, you can practice song sheet, interest.
