电梯群控调动c++实现

电梯群控是指对多台电梯进行统一的调度控制，以提高电梯的运行效率和乘客的服务质量。下面是一个简单的电梯群控调动C++实现的示例：

首先，定义一个电梯类，包括电梯状态、当前楼层、电梯运行方向、电梯内外按钮状态等信息：

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 };
};

然后，定义一个电梯控制器类，包括多台电梯、电梯状态更新、电梯调度等操作：

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;
};

以上就是一个简单的电梯群控调动C++实现的示例。注意，这只是一个简单的实现，实际上电梯群控算法非常复杂，需要考虑多种情况，如电梯负载、电梯排队等等。
