Real-time control software design the second week of work

State analysis

Described by the topic, there are only two different events, one is vehicle entry, one is vehicle departure, and the corresponding sensor signal, landing bar signal, the signal is changed together, so can be simplified into two composite states.

Code implementation

Sensor header File

////Created by Zhuhaihao on 2016/12/4.//#ifndef Statemachine_statemachine_h#defineStatemachine_statemachine_hclassSensor { Public: Sensor (); Sensor (BOOLState ); BOOLGetState ()Const; voidSetState (BOOLnewstate); voidrestore ();Private:    //here, a state is used to indicate that the vehicle enters the sensor signal and the vehicle leaves the sensor signal.//If True indicates vehicle entry false indicates the vehicle is leaving    BOOLState ;};#endif //Statemachine_statemachine_h

Sensor implementation

////Created by Zhuhaihao on 2016/12/4.//#include".. /header/sensor.h"#include<iostream>using  namespacestd; Sensor::sensor () { state=false;} Sensor::sensor (BOOLState ) {     This->state =State ;}BOOLSensor::getstate ()Const {    return  This-State ;}voidSensor::setstate (BOOLnewstate) {     This->state =newstate;}voidSensor::restore () { This->state =false;}

The code for the remaining parts is similar to the sensor. All the code here https://github.com/hacktw/RTCSD2016
