【摘要】：融雪剂乳液洒布车是一种新型的融雪化冰设备，但要实现快速、高效及环保的融雪除冰，控制系统将起着决定性作用，，实现其智能化控制是一个重要目标。 论文介绍了智能型融雪剂洒布车的发展和技术现状，查阅参考国内外智能型融雪剂洒布车相关资料及相关文章，提出了智能型融雪剂洒布车系统方案，对于控制系统原理进行了理论研究，确立控制系统的特点。 结合实际工作状况，对智能型融雪剂洒布车的洒布量控制算法进行了理论分析，得出了洒布车推荐速度与洒布量的合理匹配算法。但与实际施工中存在一定的偏差，为了减小这种偏差，提高洒布车洒布精度，在算法中引入了速度修正系数kv，经过实际验证表明：引入修正系数在一定程度上可以减小由于车速检测等不准确带来的洒布偏差。 论文分析了PLC控制的特点，PLC可以实现无需复杂的接口电路而对速度脉冲信号直接采样，而且输出信号可以直接驱动电磁阀，这些都有利于其在洒布车控制系统中的应用。最终完成了PLC控制系统的选型以及洒布车部分电气原理图的设计，给出了主要控制模块的软件流程图和控制策略。 论文以智能化控制为目标，设计方便操作的人机界面系统，为施工操作及监控提供方便。在控制系统中加入了出错报警和出错系统，为有效保护设备和施工质量提供保证。
[Abstract]:The snowmelt emulsion sprinkler is a new type of snowmelt and ice melting equipment, but the control system will play a decisive role in the realization of fast, efficient and environmentally friendly snow melting and deicing, and the realization of intelligent control is an important goal. This paper introduces the development and technology status of the intelligent snowmelt sprinkler, referring to the related information and related articles of the intelligent snowmelt sprinkler at home and abroad, and puts forward the system scheme of the intelligent snowmelt sprinkler. The theory of control system is studied, and the characteristics of control system are established. Combined with the actual working conditions, the paper theoretically analyzes the control algorithm of the sprinkler quantity of the intelligent snowmelt sprinkler, and obtains a reasonable matching algorithm between the recommended speed and the sprinkler quantity of the sprinkler. However, there is a certain deviation from the actual construction. In order to reduce the deviation and improve the sprinkler precision, The speed correction coefficient (kv,) is introduced into the algorithm. The results show that the introduction of the modified coefficient can reduce the sprinkler deviation caused by the inaccuracy of speed detection and so on. This paper analyzes the characteristics of PLC control, which can directly sample the velocity pulse signal without complicated interface circuit, and the output signal can drive the solenoid valve directly, which is beneficial to its application in the sprinkler vehicle control system. Finally, the selection of PLC control system and the design of electrical schematic diagram of sprinkler vehicle are completed, and the software flow chart and control strategy of the main control module are given. This paper aims at intelligent control and designs a convenient man-machine interface system, which provides convenience for construction operation and monitoring. The error alarm and error system are added to the control system to ensure the effective protection of equipment and construction quality.
