射线对人体是有害的,笔者设计了一种控制电路,杜绝了非受治人员误吃射线现象的发生,现将该电路工作原理介绍如下:电路工作原理:如图所示,电路由门开关 LX(行程开关),紧急停止按钮2AN、继电器 J_1,指示灯 Q,定时器 DS 等组成。1.当放射工作人员、检修人员或其他非受治人员未离开治疗室,而操作室按下工作按钮1AN 时,治疗室内人员立即按下2AN机器就不能工作,不会放出射线。
Ray is harmful to the human body, I designed a control circuit to eliminate the incidence of unmanaged radiation error phenomenon, now the circuit works as follows: Circuit works: As shown, the circuit by the door switch LX (travel switch), emergency stop button 2AN, relay J_1, light Q, timer DS and other components. 1. When radiological staff, maintenance personnel or other non-controlled persons have not left the treatment room, and the operating room presses the work button 1AN, the treatment room personnel immediately press the 2AN machine will not work, will not emit radiation.
