Vecon - con system is triggered by 4 infra - red sensors along the selected lanes with 2 in pairs . false trigger by wind shield and container - type trucks are dalian yaowan phase ii screened out and the system captures and recognizes container numbers , country codes , iso codes automatically in less than 0 . 012 seconds from trigger till image capture . the captured images are transmitted to the tos for processing which enhances efficiency and ensures security while maintaining manpower at the minimal Vecon - con透过四个红外线对射敏应触发器进行触发，两个一组并列于车道上，具备防止集装箱型卡车大型集装箱车拖头等误触发，系统接收到触发信号后，自动抓拍集装箱号码国家代码箱形代码，抓拍的图像会被传送到码头控制系统中心进行后台处理，该系统由触发到抓拍只需不多于0 . 012秒，整个系统大大提高了口岸工作效率，并减低了人力物力的耗用，为港口码头的管理提供了更加高效可靠的处理手段。
With the conduction property of the triggered thyristor and the intellective numerical controlled frequency reduction of the triggering pulse by mpu , we can divide alternating current into several complete sinusoidal waves to supply some loads . it can be made as a controller or a pcb ware , which is suitable for the air conditioning , machine tool and various instruments that require electric power or rotate speed adjustment 利用晶闸管的触发导通特性，用单片机对触发信号进行智能数字降频，可在交流电中切分出部分完整的正弦波形供负载使用，可以单独做成一台控制仪器或者作为一个控制电路板用于需要电功率和转速调节的空调、机床以及各类仪器设备中。
Based on above - mentioned schemes , the power detection system based on tms320vc5410 is designed , which realizes collection , a / d , digital signal processing . keyboard . display and uart ? the ad73360 gather chip commonly used in power system is used in front of the power detection system , and the circuit of frequency multiplication phase - locked is consisted of phase - locked loop device ? d4046 and frequency division device cd4060 to produce the gather signal of ad73360 frequently , the gather wave and re sult can be displayed on lcd 基于上述方案，本人设计开发了基于tms320vc5410的电力采集检测系统。基本实现了采集、 a d转换、数字信号处理、键盘显示、异步通信等系统软硬件设计。该系统前端采用电力系统常用的ad73360采集芯片，锁相倍频电路由锁相环cd4046与分频器cd4060一起构成，产生ad73360采集触发信号。
In the realization of the inverter control circuit , the signal from the pll is input to ir2110 via adjusting phase and forming dead time . sg3525 is selected as the core device of the chopper . meanwhile . two pulse that will input to the chopper can be obtained by simple design . besides . the circuit of which core chip is dsp is described 在逆变控制电路的具体实现中，用锁相环作为频率跟踪的核心器件，经相位调整、死区形成等环节得到两路触发信号，输入到ir2110中即可作为逆变器的驱动信号。
