Description.The preferred embodiment of irradiation processing installation security system is given in attached drawing.But irradiation processing installation security system
It can realize in many different forms, however it is not limited to embodiment described herein.On the contrary, providing these embodiments
Purpose is to keep the disclosure to irradiation processing installation security system more thorough and comprehensive.
Unless otherwise defined, all technical and scientific terms used herein and belong to technical field of the invention
The normally understood meaning of technical staff is identical.Herein in the term used in the description of irradiation processing installation security system
It is only for the purpose of describing specific embodiments and is not intended to limit the present invention.Term " and or " used herein packet
Include any and all combinations of one or more related listed items.
Referring to Fig. 1, providing a kind of irradiation processing installation security system in one of the embodiments, this is safely
System includes: level-one safety device 102, secondary safety device 104, three-level safety device 106 and PLC control device 112.Level-one
Safety device 102 is electrically connected with PLC control device 112, and the switch interlock of level-one safety device 102 and electron accelerator works；
Secondary safety device 104 and the main contactor of electron accelerator frequency conversion tank interlock work；Three-level safety device 106 and electronics accelerate
The total power switch of device interlocks work.Wherein, level-one safety device 102 is used for through PLC control device 112 to electron accelerator
It is controlled；Whether secondary safety device 104 is exceeded and whether have personnel's process for detecting irradiation dose；Three level securities dress
106 are set for cutting off the general supply of irradiation processing facility, powers off irradiation processing facility.
If secondary safety device 104 or/and three-level safety device 106 still can after level-one safety device 102 fails
Starting protection measure, if three-level safety device 106 still being capable of starting protection measure after secondary safety device 104 fails.It adopts
With multiple grade redundancy interlock system protection staff safety, the reliability for shutting down electron accelerator is greatly improved.
Specifically, the output end of level-one safety device 102 is electrically connected with the input terminal of PLC control device 112, PLC control
