实时控制软件设计第二周作业-停车场门禁控制系统状态机
画出动作转换图为:
使用模块化设计,将起落杆、出入传感器和通行灯设计成四个模块,分别继承设计好的系统模块接口:

在FSM_Execute.cpp中实现系统响应和模块动作:
1 //FSM_Execute.cpp 2 #include "FSM.h" 3 4 namespace FSM 5 { 6 void ControlSystem::Update(bool CarState) 7 { 8 //-----------检测到汽车进入,入闸传感器置为true-----------// 9 //------------------触发入闸传感器执行动作---------------// 10 if (CarState == CarIn) 11 { 12 StateReport(Car_In); 13 if ((LiftLever::GetInstance()->GetState() == Down) 14 && (Light::GetInstance()->GetState() == Red)) 15 { 16 InSensor::GetInstance()->SetState(true); 17 StateReport(InSensor_Set_True); 18 InSensor::GetInstance()->Execute(); 19 } 20 else 21 { 22 ErrorReport(Check_State_Of_LiftLever_And_Light); 23 } 24 } 25 //-----------检测到汽车出闸,出闸传感器置为true-----------// 26 //------入闸传感器置为true,触发出闸传感器执行动作--------// 27 else 28 { 29 StateReport(Car_Out); 30 if ((LiftLever::GetInstance()->GetState() == Up) 31 && (Light::GetInstance()->GetState() == Green)) 32 { 33 InSensor::GetInstance()->SetState(false); 34 OutSensor::GetInstance()->SetState(true); 35 StateReport(InSensor_Set_False); 36 StateReport(OutSensor_Set_True); 37 OutSensor::GetInstance()->Execute(); 38 } 39 else 40 { 41 ErrorReport(Check_State_Of_LiftLever_And_Light); 42 } 43 } 44 } 45 46 void LiftLever::Execute() 47 { 48 if (InSensor::GetInstance()->GetState() == true) //入闸和出闸时栏杆的执行动作不同 49 { 50 if (this->State == Up) //检查状态是否被正确切换,下同 51 { 52 Light::GetInstance()->SetState(Green); 53 StateReport(Light_Set_Green); 54 Light::GetInstance()->Execute(); 55 } 56 else 57 { 58 ErrorReport(LiftLever_May_Brokendown); 59 } 60 } 61 else if (OutSensor::GetInstance()->GetState() == true) 62 { 63 if (this->State == Down) 64 { 65 Light::GetInstance()->SetState(Red); 66 OutSensor::GetInstance()->SetState(false); 67 StateReport(Light_Set_Red); 68 StateReport(OutSensor_Set_False); 69 } 70 else 71 { 72 ErrorReport(LiftLever_May_Brokendown); 73 } 74 } 75 } 76 77 void InSensor::Execute() 78 { 79 if ((LiftLever::GetInstance()->GetState() == Down) 80 && (this->State == true)) 81 { 82 LiftLever::GetInstance()->SetState(Up); 83 StateReport(LiftLever_Up); 84 LiftLever::GetInstance()->Execute(); 85 } 86 else 87 { 88 ErrorReport(Check_State_Of_LiftLever_Or_The_InSensor_May_Brokedown); 89 } 90 } 91 92 void OutSensor::Execute() 93 { 94 if ((this->State == true)) 95 { 96 LiftLever::GetInstance()->SetState(Down); 97 StateReport(LiftLever_Down); 98 LiftLever::GetInstance()->Execute(); 99 } 100 else 101 { 102 ErrorReport(OutSensor_May_Brokendown); 103 } 104 } 105 106 void Light::Execute() 107 { 108 if ((this->State == Green) 109 && (LiftLever::GetInstance()->GetState() == Up)) 110 { 111 ControlSystem::GetInstance()->Update(CarOut); //在栏杆升起且灯变绿后汽车 112 } //可通行,更新系统状态 113 else 114 { 115 ErrorReport(Light_May_Brokendown); 116 } 117 } 118 }
以下为测试程序:
1 //main.cpp 2 #include "FSM.h" 3 4 using namespace FSM; 5 6 int main(void) 7 { 8 ControlSystem::GetInstance()->SystemInitialize(); 9 ControlSystem::GetInstance()->Update(CarIn); 10 ControlSystem::GetInstance()->SystemShutdown(); 11 system("pause"); 12 return 0; 13 }
