Question

求大神帮忙翻译成英文一下

摘要：随着时代的发展，单片机技术已经普及到我们的生活，工作，科研各个领域中，已经成为一种比较成熟的技术。本次设计的题目是基于DS18B20的温度报警器设计，用数码管与DS18B20设计的温度报警器，系统由AT89C51作为主控芯片，结合外围的控制电路和单片机的接口电路，本例将报警温度设为高：70℃，低：-20℃，当DS18B20感知到温度达到此临界值时相应的LED闪烁，同时系统发出报警声。

　　　本报警器具有设计方法合理，简单易行，成本低，，可以设置上、下报警温度，安全实用等特点，具有一定的推广价值。

Answer 1

With the development of the times, single-chip technology has spread to our lives, work, research in various fields, has become a relatively mature technology. This design topic is based on the DS18B20 temperature alarm design, digital control and DS18B20 design temperature alarm, system consists of AT89C51 as the main control chip, combined with the peripheral control circuit and MCU interface circuit, this example will alarm for high temperature : 70 ℃, -20℃, DS18B20 low: when the perceived temperature to reach the critical value LED corresponding to flicker, at the same time the system sends out alarm sound. The alarm has the design method is reasonable, simple, low cost,, can set, lower temperature alarm, safety and practicality, has certain promotion value.

Answer 2

Abstract: with the development of The Times, the single-chip microcomputer technology has spread to our life, work, scientific research fields, has become a more mature technology. The topic of this design is based on DS18B20 temperature alarm design, with a digital tube and DS18B20 design temperature alarm, the system by AT89C51 as the master control chip, combined with peripheral control circuit and MCU interface circuit, and in this case will alarm temperature set to high: 70 ℃, low: - 20 ℃, when DS18B20 perception to the temperature reaches the critical value when the corresponding LED flashing, at the same time issued a warning sound system. This alarm has design method is reasonable, simple and low cost, and can set the upper and lower alarm temperature, safe and practical characteristics, have certain value of popularization.
