摘要
目前,抑尘剂喷洒大部分采用人工上车喷洒的全手工作业方式,其缺点效率低下,费时费力,同时存在各种不安全隐患。少数新装了喷淋基站,但其喷洒量不能有效控制,没有完整的数据跟踪机制,不能对已经作业的信息进行查询和共享。针对抑尘剂喷洒现状,开发出了一套全自动抑尘剂喷洒系统,根据货车速度来改变喷淋抑制剂系统喷洒量,采用plc300的变频调速方法,采集货车行驶时间,输入plc中获得货车速度,然后对变频器的变频频率进行选择。根据不同的频率,对应不同的喷洒量;并使用组态王软件进行监控,便于对现场设备的检测与控制。
At present, most of the artificial dust suppression agent spraying car sprayed is the manual mode of operation, it has the disadvantage of low efficiency, costly and time- consuming, and there are all kinds of unsafe hidden danger. Some use a new spraying base station, but the spraying amount can not be effectively controlled, no complete data tracking mechanism, and can not query and share of job infonnation. For dust suppression agent spraying situation, an automatic dust suppression agent spraying system is created , according to the vehicle speed to change the spraying inhihitors spraying system, using frequency control method of plc300, and col- lecting the truck driving time, entering the PLC for truck speed,then it changes the frequency of the frequency converter selection, ac- cording to different frequency, corresponding to different spraying quantity; At the same time it uses Kingview software, convenient de- tection and control of field equipment.
