  • 智能电网安全保护

    Abstract: Stuxnet, a sophisticated virus that damaged Iran's nuclear capability, should be an eye openerfor the world. We can choose to learn something very narrow (how to combat the Stuxnet virus) or wecan choose to focus on the larger goal of thwarting the next type of creative cyber attack. Unfortunately,critical industrial infrastructure is not Currently designed with security as a key goal, leaving open multipleavenues for an educated and funded attacker to create massive problems. This tutorial outlines somebasic concepts that engineers and product definers should consider to make sure their new projects stayahead of future threats.

  • 基于单片机的数字化B超键盘设计

    针对目前使用的RS232接口数字化B超键盘存在PC主机启动时不能设置BIOS,提出一种PS2键盘的设计方法。基于W78E052D单片机,采用8通道串行A/D转换器设计了8个TGC电位器信息采集电路,电位器位置信息以键盘扫描码序列形式发送,正交编码器信号通过XC9536XL转换为单片机可接收的中断信号,软件接收到中断信息后等效处理成按键。结果表明,在满足开机可设置BIOS同时,又可实现超声特有功能,不需要专门设计驱动程序,接口简单,成本低。 Abstract:  Aiming at the problem of the digital ultrasonic diagnostic imaging system keyboard with RS232 interface Currently used couldn?蒺t set the BIOS when the PC boot, this paper proposed a design method of PS2 keyboards. Based on W78E052D microcontroller,designed eight TGC potentiometers information acquisition circuit with 8-channel serial A/D converter, potentiometer position information sent out with keyboard scan code sequentially.The control circuit based on XC9536 CPLD is used for converting the mechanical actions of the encoders into the signals that can be identified by the MCU, software received interrupt information and equivalently treatmented as key. The results show that the BIOS can be set to meet the boot, ultrasound specific functionality can be achieved at the same time, it does not require specially designed driver,the interface is simple and low cost.

  • 基于ARM单片机的自动测高测距小车

    生活中许多目标的高度和水平距离需要进行测量。目前主要的测量方法,仍以传统的皮尺丈量为主,测量效率不高,有时还很不方便,没有技术成熟的数字式测高测距产品。以基本的数学方法为理论依据,利用遥控小车做为载体,采用角度传感器测量角度、霍尔传感器测量水平距离等,通过单片机LM3S615进行数据计算,实现了对待测目标物体的高度、水平距离等数据的快速、精确和数字式的测量,高度测量精度可达99.06%,水平测量精度则可达98.06%。 Abstract:  In our lives, the height and horizontal distance of some goals are needed to be measured. Because the Currently used methods are still traditional tape-based measuring methods, and the measuring efficiency is low and inconvenient so some kinds of digital and portable measuring methods or instruments are needed. Based on the basic math theory, this paper designed and manufactured a portable, digital and remote controlled measuring mobile small vehicle, which assembled with angle measuring sensor for angle measurement and Hall sensor for horizontal distance measuring. MCU LM3S615 calculated the height and horizontal distance data gotten from these sensors. The measuring process is simple, the measuring results are more accurate and the measuring efficiency is higher than traditional measure instruments. The accuracy of height and distance measurement can reach 99.06% and 98.06%.

  • 基于双ATmega128的安检力学试验机设计

    针对当前安检力学试验机所能完成的试验种类单一、自动化程度低等问题,提出一种以ATmega128单片机为核心控制器的安检力学试验机的设计。详细阐述了该安检力学试验机各个组成部分的设计原理和方案,并且给出了各部分的软件设计思想和操作流程。经过大量测试试验表明:设计的安检力学试验机可以完成多达十余种的力学安检试验,完全符合相关国家标准,并且具有数据采集精度高、传输速度快、操作安全简便等特点,实现了安检设备的多功能化、数字化和自动化。 Abstract:  Currently, many mechanical security testing machines have only one function. The degree of automation of them is low. To solve those problems, a new kind of mechanical security testing machine, using ATmega128 micro-controller as its core controller, has been advanced. It describes the components of the machine. The principles and the scheme in the designing processes are presented in detail, and the software architecture and the operation processes of each part are given. After having done many testing, we have reached the following conclusions: the mechanical security testing machine presented can do over ten mechanical security tests complying with related national standards. It has high data acquisition accuracy and high transmission speed. The operation of the machine is simple and safe. In general, this machine is a multi-functional, highly automatic, digitalized security testing device.

  • MAX7060的ASK_FSK的ISM射频发射机

    Abstract: This application note illustrates the flexibility of the MAX7060 ASK/FSK transmitter. While the Currently available evaluationkit (EV kit) has been optimized for the device's use in a specific frequency band (i.e., 288MHz to 390MHz), this document addresseshow the EV kit circuitry can be modified for improved operation at 433.92MHz, a frequency commonly used in Europe. Twoalternative match and filter configurations are presented: one for optimizing drain efficiency, the other for achieving higher transmitpower. Features and capabilities of earlier Maxim industrial, scientific, and medical radio-frequency (ISM-RF) transmitters areprovided, allowing comparison of the MAX7060 to its predecessors. Several design guidelines and cautions for using the MAX7060are discussed.
