摘要
利用可编程控制器(PLC)控制步进电机和烧蚀枪,实现了绝热材料烧蚀过程的自动化控制。克服了目前烧蚀仪采用普通电机-继电器控制,具有接线复杂、体积大、自动化程度低、计时精度低等缺点。利用PLC控制步进电机的转向和转速,从而控制烧蚀枪的运动轨迹,通过烧蚀试验得出可靠的烧蚀规范参数。经过烧蚀试验证明,研制出的新型绝热材料烧蚀仪噪声小,升降速过程快,能够实现烧蚀枪的精确定位,对提高系统的可靠性和工作效率具有重要意义。
The stepping motor and ablating gun controlled by PLC system can realize automatic control of the ablation for adiabatic material. The traditional ablating instrument with general motor relay-contactor has disadvantages of complex circuit, big volume and low degree of automation, which have been overcame. Adopting PLC to control the stepping motor turning speed and direction as well as the motion curve of ablating gun, and a group of typical ablating parameters can be obtained by the ablating experiment. The ablating test shows that the new ablating equipment for adiabatic material has advantages of small noise and fast speed in acceleration and deceleration, which is of great significance for enhancing the system reliability and efficiency.
