自动调平系统在防空火炮中的应用

火炮自动调平控制系统由PLC、2倾角传感器和1套液压执行机构组成.包括火炮状态转换控制和射击时关闭调平、射击结束恢复调平控制.自动调平过程中,传感器分别检测炮床X、Y轴方向水平状态,与误差设定值比较并将结果传给PLC.PLC根据预置程序输出调平信号,分别控制各电液换向阀,经液压执行机构改变炮床水平倾角消除水平误差,实现自动调平.

Application of Automatic Controlling System for Adjusting Level in Antiaircraft Artillery

Automatic controlling system for adjusting level in antiaircraft artillery is composed of PLC, 2 pieces of slope sensor of and a set of performing machine. Including the two controlling processes of changing state of the artillery and adjusting level before and after shooting. In the course of adjusting level, the two sensors check the states of level of X and Y directions of artillery-bed respectively, and compare to the values of error set in advance, then send the results to PLC. PLC will put the controlling signals out according to the programs designed in advance to control the electronic-liquid valves to exchange. The errors of artillery-bed level will disappear caused by the changes of performing hydraulic pressure machine. So it will come to adjusting level automatically.
