On August 26, 2012, the acceptance meeting of science and technology projects was hosted by the Xuzhou Science and Technology Bureau. Our company's "Research on Intelligent Control System for Spraying Cold Road Recycling Machines" project was praised by the participating experts and passed the acceptance. The official acceptance certificate was approved on the day.

This project focuses on solving four key technical issues:

1. Determined the correspondence between the optimal spraying amount of the control system, vehicle speed, and milling depth;

2. Research on the detection and design of key parameters for Road cold recycler models;

3. Solve the key technical problems of control algorithm selection, and achieved better control results;

4. Solve the problem of the operational reliability of the control system.

Project research innovations:

1. Established the mathematical model of spray control system for pavement Road cold recycler machine:

2. A water spray flow control method based on fuzzy PID composite control is proposed;

3. Developed a set of intelligent spray control system for pavement Road cold recycler machine.
