根据~(60)Co辐照室机电运行的特点,我们在一座装有5000克镭当量辐射源的农用钴室设计中,采用了电子程序自动控制装置。当程控器处于“自动”工作状态时,能对钴室机械实现“响铃——锁门——升源——辐照——降源——开门——响铃”的控制过程。现经500余次空白试车以及钴源安装以来的运行,程序控制系统一直工作正常。 According to the electromechanical operation of the ~ (60) Co irradiation chamber, we adopted an automatic electronic program control device in an agricultural cobalt chamber designed with a radiation source of 5000 g radium equivalent. When the programmable controller is in the “automatic” working state, the control of the cobalt chamber machinery can be realized by “ringing - lock door - rising source - irradiating - falling source - opening door - ringing”. Now more than 500 blank test run and the cobalt source installed since the operation of the program control system has been working properly.
