基于莫尔型状态机的简易状态机交通灯控制系统设计代码

基于莫尔型（ Moore 图）的状态机用于交通信号灯控制系统的设计，通常采用固定的输入和输出关联规则。以下是一个简单的Python伪代码示例，描述了如何创建一个四路口交通灯控制系统的状态机：

class TrafficLightStateMachine:
    def __init__(self):
        self.states = {
            "Red": {"NorthSouth": "Green", "EastWest": "Yellow"},
            "Green": {"NorthSouth": "Yellow", "EastWest": "Red"},
            "Yellow": {"NorthSouth": "Red", "EastWest": "Red"}
        }
        self.current_state = "Red"

    def update(self, direction):
        next_state = self.states[self.current_state][direction]
        print(f"{direction} turning is {next_state}")
        self.current_state = next_state

# 实例化并开始操作
traffic_light = TrafficLightStateMachine()
while True:
    # 用户输入方向（例如："North"、"South"、"East"、"West"）
    user_direction = input("Enter direction (North/South/East/West): ")
    
    # 更新对应的方向灯状态
    traffic_light.update(user_direction)
    time.sleep(3)  # 模拟红绿黄灯切换时间，这里实际应用可能需要硬件延时
