"基于LabVIEW的交通信号灯绿波带设计：毕业设计论文研究"

The "green wave band" refers to a situation where vehicles travel at a certain speed on a certain road section. If they encounter a red light at the first intersection, all subsequent intersections will have green lights; if they encounter a green light at the first intersection, all subsequent intersections will also have green lights, as if driving in a smooth and unobstructed green screen, hence the name "green wave band". LabVIEW is a graphical programming language that uses icons instead of text to create applications. This paper first analyzes the practical application and development status of the green wave band, and then focuses on the design process of the traffic signal green wave band based on LabVIEW software. By using functions such as case structures, for loops, and basic algorithm of modulo operation, the countdown control of traffic lights is achieved, and the timed counting in the program can be set manually. The flexible human-computer interaction fully leverages the characteristics of virtual instrument software. Then, using the AND gate and NOT gate structure of the 74LS04 and 74LS08 chips, a hardware circuit is built on the ELVIS platform, which effectively establishes communication between the computer and the platform. In the final debugging process, the entire system can reflect the function of the green wave band well, and clearly display the adjustability of the green wave band.
