基于预置区域数据表的自摆式大流量消防炮控制系统设计

为克服现有自摆式消防炮依靠复杂的机械传动结构实现自摆的不足，设计一种基于预置区域数据表的自摆式大流量消防炮控制系统。当火灾发生时，消防炮通过程序方式调用预先设置的水平摆动角度库和俯仰步进角度库，控制水平、俯仰直流电机的转动方向和角度，进而完成消防炮的自摆式运动；采用H桥功率驱动电路完成对直流电机的驱动，利用编码器实时检测水平、俯仰机构的位置角度，采用STM32L0系列超低功耗单片机控制自摆式大流量消防炮。该消防炮具有无线遥控功能，可供操作人员远距离操作。该系统性能稳定，依附程序控制的方法实现消防炮的自摆式运动，在实际应用场所中取得良好效果。

Design of Control System for Self-pendulum Large Flow Fire Gun Based on Preset Area Data Table

As for the fire fighting in parallel, uniform stacking and other large space places, the existing self swinging fire gun has the defects of self swing motion and independent program motion. A self-tilting large flow fire gun control system is designed based on preset area data table. When the fire break out, the fire gun calls the preset horizontal swinging angle library and the pitching step angle library to control the rotation direction and angle of the horizontal and pitching DC motor through the program mode, thus completing the self-swinging movement of the fire gun. The H bridge power drive circuit was used to drive the DC motor. An encoder was employed to detect the angular position of the horizontal pitching mechanism in real time and STM32L0 series ultralow power MCU was utilized to control self-oscillating large flow fire gun. At the same time, the fire gun has wireless remote control function and it can be operated remotely by operators. The system is stable in performance. The method of program control is adopted to realize the self-swinging motion of the fire gun and good results have been achieved in application.
