Application of Automatic Controlling System for Adjusting Level in Antiaircraft Artillery

TAN Qing, FU Ke-ming (College of Electromechanical Engineering, Central South University, Changsha 410083, China )  
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.
