Logical structure and realization method of safety interlock for proton therapy apparatus

摘要

The present invention provides a logic structure and an implementation method of a safety interlock for a proton therapy apparatus.Logical structure of the safety interlock for proton therapy equipment isIncludes hard wired structures and topological structuresHard wired and topological structuresFirst safety interlock systemSecond safety interlock system (2).First treatment room (11),Contains a second therapy chamberThe components of each safety interlock system and therapy room areHostPLC 1The first safety interlock system (including 1) and the PLC 2 and the switch.ExchangeA second safety interlock system including plc1 and remote PLC 2ExchangeFirst treatment room (11) including PLC and compass TrioExchangeA second treatment room (12) including PLC and compass Trios.According to the present invention, the safety interlock subsystem can be quickly controlled by constructing the whole of the safety interlock system by two methods, and an operation for detecting the operating state of the apparatus can be performed.By processing in parallel in two methods, not only does it satisfy the demand of the response time, but also the function of the monitoring can be fulfilled.Diagram
