摘　　要：γ射线探伤机自动控制仪是γ射线探伤机自动送收源的电气产品,有多种安全联锁功能。本系统的设计主要完成的功能是通过人机界面预置参数,由可编程控制器(PLC)根据预置参数精确控制伺服电机转动,完成γ射线探伤源的精确定位,实现被检测工件探伤曝光,同时能够有效减少冲击对送源软轴的损坏。通过各种可靠的安全连锁装置,处理探伤工作中各种异常情况的发生。运动过程采用闭环控制,整个系统具有较高的测量精确度和可靠性,达到对γ射线探伤机自动完成"送源—曝光—收源"的精确控制。The automatic control device of γ-ray detection machine is a kind of electrical product of γ-ray detector, which has many kinds of safety interlocking functions. The main function of this system is to control the servo motor rotation precisely according to preset parameters by programmable controller （PLC） through pre-setting parameters of man-machine interface, to complete the accurate positioning of γ-ray detection source, to realize the detection of workpiece exposure , At the same time can effectively reduce the impact of the damage to the source flexible shaft. Through a variety of reliable safety interlock device, dealing with various anomalies in the detection of the occurrence of the work. The whole system has high precision and reliability, and it can control the γ-ray detector automatically. It can control the source-expose-receive-source automatically.
