求助：汉译英—基于单片机的简易数字时钟系统~~~

RT

文本如下：

近些年，随着科技的发展和社会的进步，人们对于时钟的要求也越来越高，传统的时钟已不能满足人们的需求，这就为数字时钟的广泛应用而奠定了基础。目前，单片机作为数字时钟的应用基础已经非常普遍，本文正是基于这种设计理念，以单片机为控制核心，设计制作一个符合指标要求的数字时钟系统设计。

本设计是以单片机芯片STC89C51为核心控制器，通过硬件电路的制作及软件程序的编制，设计制作出一个简易数字时钟系统。该时钟系统包括时钟模块，闹钟模块，液晶显示模块、键盘控制模块以及信号提示模块。系统具有简单清晰的作界面，能在5V的直流电源下正常工作，能够准确显示时间，且可随时进行调整，并具有闹钟时间设置、闹钟显示和止闹功能。设计以硬件软件化为指导思想，充分发挥单片机功能，大部分功能通过软件编程来实现，电路简单明了，系统稳定性高。同时，该时钟系统还具有功耗小、成本低的特点，具有很强的实用性。由于系统所用元器件较少，单片机所被占用的I/O口不多，因此该系统也具有一定的可扩展性。

不要是翻译器翻译的，谢谢啦~~~

In recent years, with the technological development and social progress, people are increasingly high requirements clocks, traditional clocks can not meet people's needs, which for the digital clock, laid the foundation for broad applications. At present, the microcontroller as a digital clock application base is already very common, this article is based on this design concept, single-chip microcomputer to control the core, designed in line with target requirements of a digital clock system design.

This design is based on Microcontroller STC89C51 as the core controller, through the production of the hardware circuits and software programming for the design to produce a simple digital clock system. The clock system consists of the clock module, alarm module, liquid crystal display module, keyboard control module, and signal prompt module. System has a simple and clear as interface can 5V DC power supply to work, be able to accurately display the time, and can be adjusted at any time, and has set the alarm time, alarm clock display, and only the downtown features. Design hardware and software into the guiding ideology, give full play to microcontroller functions, most of the functionality through software programming to implement, the circuit simple and clear, high stability of the system. Meanwhile, the clock system also has a power consumption and low cost features, has a strong practicality. Because the system used by fewer components, single chip occupied by the I / O port small, so the system also has a certain degree of scalability.
