When the simulation vehicle is running, if the first limit sensor 4 works normally, the simulation vehicle will move in the opposite direction after hitting the limit sensor 4 and continue the dust suppression experiment; if the first limit sensor 4 fails, the simulation vehicle will continue to move forward and trigger the second limit sensor 4. After the central control unit 7 receives the signal of the second limit sensor 4, it immediately controls the simulation vehicle to stop running and issues an alarm signal to ensure the safety and reliability of the experimental process.

[0036] The working principle of the present invention will be further described below in conjunction with specific embodiments:

[0037] Place the simulation vehicle used for the intelligent road dust suppression dynamic simulation experiment on the track covered with dust and complete the preparatory work. The preparatory work includes setting the first limit sensor 4 on one side of the device operation track. When the device runs normally and touches this limit sensor 4, it will move in the reverse direction. The second limit sensor 4 is about 200 mm away from the first limit sensor 4. Set the first dust sensor 21, the second dust sensor 22, the third dust sensor 23, and the fourth dust sensor 24 behind the four wheels of the simulation vehicle, all of which are electrically connected to the central control unit 7. Set an optoelectronic sensor 3 on the simulation vehicle. The simulation vehicle has two modes: manual and automatic. In the manual mode, it is necessary to manually control the simulation vehicle to move back and forth, observe the changes in the running speed and the values of the PM100 dust sensor 2, and the wheel indentations on the road surface, etc. In the automatic mode, set the vehicle speed, the number of running times, and the parking waiting time through the touch screen, mobile phone, tablet, or computer. The number of running times refers to one time when the forward movement of the simulation vehicle is detected by the optoelectronic switch or one time when the backward movement is detected by the optoelectronic switch. The parking waiting time refers to the waiting time after the intelligent road dust suppression dynamic simulation experiment device runs to the set number of running times and touches the limit sensor 4 in the running direction of the simulation vehicle and stops. After starting, the simulation vehicle performs a reciprocating cyclic movement according to the set parameters. When it reaches the number of running times, it enters the parking waiting time stage. When the parking waiting time arrives, it starts the next cyclic operation. When the simulation vehicle is running, continuously detect the changes in the dust amount at different speeds, and conduct big data report summary and analysis through the cloud platform 9 to provide technical parameter support for the spraying of dust suppressant. When the motor 5 fails, the simulation vehicle stops running and alarms. When the device runs normally, it does not touch the second limit sensor 4. When the second limit sensor 4 is triggered, it indicates that the first limit sensor 4 has failed, and the central control unit 7 controls the simulation vehicle to stop running and alarms.

[0038] The control circuit of this embodiment is as Figure 2 , 3 shown. The input end 71 of the central control unit is connected to the optoelectronic sensor 3 and the limit sensor 4, and the output end is connected to the intermediate relay to control the frequency converter 6 and the alarm light. The central control unit 7 obtains the current values by collecting the signals of the dust sensor 2 and the frequency converter 6 and uploads them to the cloud platform 9. The central control unit 7 controls the operation and stop of the motor 5 through the data fed back by the optoelectronic sensor 3 and the limit sensor 4. The system power supply is connected to the motor 5 through the circuit breaker QF0, the circuit breaker QF1, and the frequency converter 6VFD. QF2 is the circuit breaker switch of the switching power supply DC24V, QF3 is the circuit breaker switch of the central control unit 7, and QF4 and QF5 are the circuit breaker switches of the fan.

[0039] In summary, an intelligent road dust suppression dynamic simulation experimental device provided by the present utility model provides accurate data support for dust suppression experiments by setting a variety of sensors, remote monitoring and control. By setting a motor fault detection circuit, the stable operation of the experimental device is ensured.
