【群控】通过adb命令实现接打电话&发短信脚本

电梯群控是指对多台电梯停行统一的调治控制，以进步电梯的运止效率和乘客的效劳量质。下面是一个简略的电梯群控换与C++真现的示例： 首先，界说一个电梯类，蕴含电梯形态、当前楼层、电梯运止标的目的、电梯内外按钮形态等信息： ```c++ class Elevator { public: enum State { IDLE, UP, DOWN }; Elevator(int maxFloor) : m_maxFloor(maxFloor), m_state(IDLE), m_floor(1) {} State state() const { return m_state; } int floor() const { return m_floor; } void pressButton(int floor) { m_buttons[floor] = true; } bool isButtonPressed(int floor) const { return m_buttons[floor]; } void openDoor() { m_doorOpen = true; } void closeDoor() { m_doorOpen = false; } bool isDoorOpen() const { return m_doorOpen; } void moveUp() { m_floor++; } void moveDown() { m_floor--; } bool canMoveUp() const { return m_floor < m_maxFloor; } bool canMoveDown() const { return m_floor > 1; } void setState(State state) { m_state = state; } private: int m_maxFloor; State m_state; int m_floor; bool m_doorOpen = false; bool m_buttons[MAX_FLOOR] = { false }; }; ``` 而后，界说一个电梯控制器类，蕴含多台电梯、电梯形态更新、电梯调治等收配： ```c++ class ElevatorController { public: ElevatorController(int numElevators, int maxFloor) : m_numElevators(numElevators), m_maxFloor(maxFloor), m_elevators(numElevators, Elevator(maxFloor)) {} void update() { for (int i = 0; i < m_numElevators; i++) { Elevator& elevator = m_elevators[i]; switch (elevator.state()) { case Elevator::IDLE: if (elevator.isButtonPressed(elevator.floor())) { elevator.openDoor(); elevator.pressButton(elevator.floor()); } else { int nextFloor = getNextFloor(i); if (nextFloor != -1) { if (nextFloor > elevator.floor()) { elevator.setState(Elevator::UP); } else if (nextFloor < elevator.floor()) { elevator.setState(Elevator::DOWN); } } } break; case Elevator::UP: if (elevator.isDoorOpen()) { elevator.closeDoor(); continue; } if (elevator.canMoveUp()) { elevator.moveUp(); int floor = elevator.floor(); if (elevator.isButtonPressed(floor)) { elevator.openDoor(); elevator.pressButton(floor); } else if (getNextFloor(i) == floor) { elevator.setState(Elevator::IDLE); } } else { elevator.setState(Elevator::DOWN); } break; case Elevator::DOWN: if (elevator.isDoorOpen()) { elevator.closeDoor(); continue; } if (elevator.canMoveDown()) { elevator.moveDown(); int floor = elevator.floor(); if (elevator.isButtonPressed(floor)) { elevator.openDoor(); elevator.pressButton(floor); } else if (getNextFloor(i) == floor) { elevator.setState(Elevator::IDLE); } } else { elevator.setState(Elevator::UP); } break; } } } void pressButton(int floor) { for (int i = 0; i < m_numElevators; i++) { Elevator& elevator = m_elevators[i]; if (elevator.isDoorOpen() && elevator.floor() == floor) { elevator.closeDoor(); return; } if (elevator.state() == Elevator::IDLE) { elevator.pressButton(floor); elevator.setState(Elevator::UP); return; } if (elevator.state() == Elevator::UP && floor > elevator.floor() || elevator.state() == Elevator::DOWN && floor < elevator.floor()) { elevator.pressButton(floor); return; } } // no available elevator } private: int getNextFloor(int index) const { const Elevator& elevator = m_elevators[index]; for (int i = elevator.floor() + 1; i <= m_maxFloor; i++) { if (elevator.isButtonPressed(i)) { return i; } } for (int i = elevator.floor() - 1; i >= 1; i--) { if (elevator.isButtonPressed(i)) { return i; } } return -1; } int m_numElevators; int m_maxFloor; std::vector<Elevator> m_elevators; }; ``` 以上便是一个简略的电梯群控换与C++真现的示例。留心，那只是一个简略的真现，真际上电梯群控算法很是复纯，须要思考多种状况，如电梯负载、电梯排队等等。
