Question

求求哪位高手给我翻译一下这个，谢谢了，急急急！！！

随着现代科技的高速发展，人们对通信的需求日益增强，无线通信网络无疑是通信事业中发展最快的，多种通信电器进入家庭，同时也引来了人们的争议：无线通信中所用电器产生的电磁辐射是否对人体有伤害，这些电器的电磁辐射有多大呢?本设计对无线网络中的电磁辐射进行分析和研究。设计采用AT89S52单片机作为核心控制芯片，首先将电磁信号转换为电信号，并将此信号电压送往模数转换芯片进行模数转换，最后由单片机对数字信号做处理和分析，并在显示器上显示出当前的辐射值。
对多功能电磁辐射检测仪检测辐射这个基本功能外，可根据需要在单片机支持的情况下做很多其他辅助功能，充分利用单片机的资源实现尽可能多的有意义的功能，体现现代电子系统智能特性。测距，作为辐射检测电路中也是必不可少的，虽然我们做的是基于单片机的多功能电磁辐射测试仪，可是人体的安全辐射是与距离有很大的相连，自此我还基于单片机做了超声波测距仪。用单片机控制超声波的发射电路、接受电路以及进行数据处理，再用液晶显示屏进行数据的显示。因为声音传播的速度会随着温度的变化而改变，所以，我们还增加了温控装置，即通过温度传感器（18B20），把现场温度信息传给单片机，再通过一定的算法，得到当前的温度值。操作者可以通过液晶显示屏很容易的观察到辐射仪和辐射源的距离和辐射值。

Answer 1

Along with the rapid development of modern science and technology, the demand of communication, wireless communication network is the fastest growing business communication, various communication appliances in the home, and also attracted people's controversial: wireless communication in electrical produces electromagnetism radiation damage to human body, there are the electromagnetic radiation? The design of wireless network of electromagnetic radiation are analyzed and studied. AT89S52 SCM design as the core control chip, electromagnetic signals are converted to first signal, and the signal voltage to digital converter chip microcontroller, finally by frequency-field on digital signal processing and analysis, and do the display is shown on the current value of radiation.
The electromagnetic radiation detector test of the basic functions, radiation in SCM according to needs the support of many other auxiliary function, make full use of the resources to achieve the microcontroller as much meaningful functional, modern electronic system intelligence characteristics. As the radiation detection range, circuit is indispensable, although we do is based on single chip multi-function electromagnetic radiation tester, but human safety radiation is connected with the great distance, I still made ultrasonic based on single chip rangefinder. With the launch of single-chip microcomputer control ultrasonic receiving circuit circuit, and data processing, reoccupy LCD display data. Because of the speed of sound travels with temperature changes, so, we will also increase the temperature, temperature sensors device through the site, 18B20) (temperature information to microcontroller, again through certain algorithm, get the current value. Operator can easily through liquid crystal display the observed radiation sources and the distance and radiation.

Answer 2

With the rapid development of modern technology, people growing demand for communications, wireless networking is undoubtedly the fastest growing telecommunications industry, multiple communication Dianqi into the family, but also attracts the people of the controversy: the use of wireless communication in electrical whether the electromagnetic radiation generated by the human body injury, these appliances electromagnetic radiation be? the design of wireless network analysis and study of electromagnetic radiation. Design uses a microcontroller as a core control chip AT89S52, first electromagnetic signal into an electrical signal and the signal voltage is sent to the analog-digital conversion chip for analog-digital conversion, and finally by the microcontroller to do the digital signal processing and analysis, and the display shows the current radiation values.

    Electromagnetic radiation on the multi-detector test the basic features of radiation, can require the Qing Kuang Zhi Chi in SCM under other Henduo other auxiliary functions, Chongfen use of MCU resources to achieve the sense of function Jinkenengduo, reflect the modern Dianzi 系统 Intelligence of . Ranging, as the radiation detection circuit is also essential, although we do is based on the single chip multi-functional electromagnetic radiation tester, but the safety of human radiation is linked with the great distance, since I do based on single chip ultrasonic range finder. Chip microcomputer controlled ultrasonic transmitter circuit, receiving circuit as well as data processing, data re-use LCD display. Because the speed of sound propagation will change with temperature change, so we increased the temperature control device, namely, by the temperature sensor (18B20), the scene temperature information to the microcontroller, and then through a certain algorithm, get the current temperature value. Operator through the LCD screen can be easily observed from the radiometer and radiation sources and radiation values.
