14725 该信号发生器以STM32单片机为核心控制单元,通过对单片机定时器的控制来实现对输出波形的频率、电压幅值、占空比的连续调节,并能对输出信号参数进行实时显示。 Due to the requirements of the output waveform, STM32 chip microcomputer is served as its control unit, so the output waveform parameters of frequency, amplitude and duty ratio can be regulated continuously, and displayed real time.
14726 经实验验证,该信号发生器便于观察和调节,完全满教学和生产中对PWM信号发生器高精度和经济性的要求。 As experiment results shown, the system is convenient to adjust and observe, and meets the needs of the high-accuracy and economy of education and produce.
14727 近年来,"富贵病"已逐渐成为危害我国居民身体健康的重要杀手之一,营养的均衡与居民的健康息息相关。 In recent years, the “richness disease” has gradually become one of the important killers endangering the health of our residents, and the balance of nutrition is closely related to the health of the residents.
14728 针对"儿童多数不喜欢吃瓜果蔬菜,挑食现象日益严重"等现象,设计了一款基于PLC的儿童营养果蔬面生产设备控制系统,给出了其总体方案设计、硬软件设计等,并进行了仿真验证,仿真结果表明:所设计的控制系统正确有效。 Aiming at the phenomenon of “most children don't like to eat fruits, vegetables, and picky eaters are becoming more and more serious”, a PLC-based control system for children's nutritional fruit and vegetable noodle production equipment was designed. The overall scheme design, hardware and software design are given. At the same time, the control system was verified by simulation. The simulation results show that the designed control system is correct and effective.
14729 本文基于Intel8086处理器设计了一个点阵式交通信号控制器,利用8×8点阵控制实现十字路口红、绿、黄箭头自动交替显示。 In this paper, a dot matrix traffic signal controller is designed based on Intel8086 microcontroller, and the 8×8 dot matrix control is used to realize the automatic alternating display of red, green and yellow arrows at intersections.
14730 同时,还设计了手动切换通行状态、全路口禁行以及深夜黄色箭头闪烁通行等多种模式,能够有效地提升十字路口通行效率、改善道路拥堵、方便市民出行。 Meanwhile, it also designs various modes, such as manual switching of traffic status, banning traffic at all intersections and flashing yellow arrow at night, which can effectively improve traffic efficiency at intersections, improve road congestion and facilitate citizens' travel.
14731 驾驶员驶车进出隧道时,常会因隧道内外光线的急剧变化产生耀眼、看不清前方道路状况等短暂致盲现象,从而引发交通事故。 When driving in and out of the tunnel, drivers often cause blindness such as dazzling and unclear road conditions in front of the tunnel due to the sharp changes of light inside and outside the tunnel, which leads to traffic accidents.
14732 本文提出一种缓解此类交通现状的交通安全装置,减少隧道口的事故发生率。 Therefore, we have made a traffic safety device under the premise of complying with the national laws, so as to alleviate this traffic phenomenon and reduce the accident rate at the tunnel mouth.
14733 通过现有车辆感应技术获取汽车的状况,将得到的数据通过隧道出入口的两个计数器进行对比从而控制隧道内部的灯光,再将数据上传至数据库; The current induction coil technology is used to obtain the status of the vehicle, and the data is compared by two counters at the entrance and exit of the tunnel to control the lights inside the tunnel and upload the data to the database; Traffic indicator light is installed at the entrance and exit of tunnel.
14734 在隧道出入口出安装交通指示灯,司机可通过信号指示灯获知前方道路状况,有效改善致盲现状。 The driver can know the road condition ahead by the hint of the signal indicator light.
