数字电子钟方案简介说明书数字电子钟不但可以显示当前的时间，而且可以显示日期、农历、以及星期等，给人们的生活带来了方便。另外数字钟还具备秒表和闹钟功能，且闹钟铃声可自选，-Digital electronic clock program profiles specification digital electronic clock not only can display the current time, and can display the date, lunar, as well as the weeks and so on, to people

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.

本例载波频率为20KHz，或载波周期为50μs。DSP晶振10MHz，内部4倍频，时钟频率为40MHz，计数周期为25ns。假设调制波频率由外部输入（1～50Hz），并转换成合适的格式（本例为Q4格式）。调制系数M为0～0.9。死区时间1.6μs。最小删除脉宽3μs。 主程序的工作是根据输入的调制波频率计算N、2N和M值。 -Example for the carrier frequency 20KHz, or carrier period is 50μs. DSP crystal 10MHz, internal 4 multiplier, the clock frequency of 40MHz, counting cycle 25ns. Assuming wave frequency modulation by external input (1 ~ 50Hz), and converted into an appropriate format (in this case for Q4 format). Modulation coefficient M is 0 ~ 0.9. Dead time 1.6μs. Delete the smallest pulse width 3μs. The work of the main program is based on input frequency modulation wave calculation of N, 2N and M values.

本档含详细的电路原理、源程序，AT89C51主控，利用车辆检测器不仅可开发电子警察，还可开发出如：自动显示泊车数的停车场，实时配时的路口信号机系统，自动车库，交通车流量计数器等。-The file containing detailed circuit principle, source, AT89C51 master the use of vehicle detector electronics can be developed not only the police, but also developed such as: automatically displays the number of parking spaces car park, with real-time signal at the junction system, automatic garage, traffic flow, such as counters.
