本文介绍了防冻液喷洒自动控制系统的组成,工作原理,控制方案。系统通过PLC集中控制,针对煤内喷洒和空车厢喷洒分别提出了不同的控制方案,实现了防冻液喷洒的智能控制,完成了喷洒量与煤量的最佳配比,节约了防冻液喷洒量,避免了由于防冻液的流失引起的路基下沉等严重的后果,具有广阔的应用前景。 This article describes the antifreeze spray automatic control system composition, working principle, control program. The system through the PLC centralized control for coal and empty car spray were sprayed were put forward different control programs to achieve the intelligent control of antifreeze spray to complete the spray volume and the best ratio of coal to save the amount of antifreeze spray , To avoid the serious consequences of roadbed sinking due to the loss of antifreeze and has broad application prospects.
