[Other] Trafficlight DL : 0: 系统设置一个两位BCD码倒计时计数器（计数脉冲1HZ），用于记录各状态持续时间；因为各状态持续时间不一致，所以上述计数器应置入不同的预置数；倒计时计数值输出至二个数码管显示；程序共设置4个进程： ① 进程P1、P2和P3构成两个带有预置数功能的十进制计数器，其中P1和P3分别为个位和十位计数器，P2产生个位向十位的进位信号； ② P4是状态寄存器，控制状态的转换，并输出6盏交通灯的控制信号。-System to set up a two BCD code countdown counter (count pulse 1HZ), used to record the duration of each state because the duration of each state are inconsistent, so these counters should be placed in several different presets countdown of numerical output to two digital display procedures were set up four processes: ① process P1, P2 and P3 form two functions with a preset number of decimal counters, of which P1 and P3, respectively, for months, and 10-bit counters, P2 to generate a 10-bit The binary signal ② P4 is the status register, control the state of the conversion, and six output control signals of traffic lights.

[Other] 1 DL : 0: 十字路口交通信号灯PLC控制系统,本文设计了基于PLC控制的交通信号灯控制系统。该系统选用的可编程逻辑控制器是德国西门子公司的S7-200，具有一定的智能性，即可以根据路面车流量大小对十字路口的交通信号灯按高峰期、正常期和晚间几个时段进行分时控制。-Intersection traffic signal control system PLC, the paper design of PLC based control of traffic signal control system. The system is optional programmable logic controller is the German company Siemens S7-200, has a certain intelligence, that is, the road traffic flow based on the size of the traffic lights at the crossroads by the peak of the normal period and the evening for several hours Time control.

[Other] traffic DL : 0: 实现路口交通灯系统的控制方法很多，可以用标准逻辑器件，可编程控制器PLC，单片机等方案来实现。但是这些控制方法的功能修改及调试都需要硬件电路的支持，在一定程度上增加了功能修改及系统调试的困难。因此，在设计中采用EDA技术，应用目前广泛应用的Verilog HDL硬件电路描述语言，实现交通灯系统控制器的设计，利用MAX+PLUS 集成开发环境进行综合、仿真，并下载到CPLD可编程逻辑器件中，完成系统的控制作用。-Intersection traffic signal systems to achieve the control of many ways you can use standard logic devices, programmable logic controller PLC, microcontroller and other programs to achieve. However, the functions of these control methods require modification and debugging support for hardware circuit, to a certain extent, an increase of functional modifications and system debugging difficulties. Thus, in the design using EDA technologies, applications, the widely used Verilog HDL hardware circuit description language to realize the design of traffic signal system controller, using MAX+ PLUS a comprehensive integrated development environment, simulation, and downloaded to the CPLD programmable logic devices to complete the system control role.

[Other] jiaotongdeng-zong DL : 0: 交通信号灯控制系统：设有一个十字路口，1、3为南，北方向，2、4为东，西方向。初始化之后，1、3路口的绿灯亮，2、4路口的红灯亮，1、3路口方向通车。延迟一段时间（30秒）后，1、3路口的绿灯熄灭，而1、3路口的黄灯开始闪烁。闪烁3次（延时3秒）后，1、3路口的红灯亮，同时2、4路口的绿灯亮，2、4路口方向开始通车。延迟一段时间（30秒）后，2、4路口的绿灯熄灭，而黄灯开始闪烁。闪烁3次（延时3秒）后，再切换到1、3路口方向。-Traffic signal control system: there is a crossroads, and 1,3 for the south, north, 2,4 for the East and West direction. After initialization, the 1,3 intersection of green light, red light junction 2,4, 1,3 direction of traffic intersection. Delay time (30 seconds), the 1,3 intersection green light is off, and the intersection of the yellow light starts flashing 1,3. Flashes 3 times (delay 3 seconds), 1,3 intersection red light, green light while crossing 2,4, 2,4 junction opened to traffic direction. Delay time (30 seconds), the 2,4 intersection green light is off, the yellow light starts flashing. Flashes 3 times (delay 3 seconds), then switch to the 1,3 junction direction.
