  Shanghai Proton Therapy Facility is in the phase of commissioning. We developed the treatment control system in consideration of a plurality of IEC standards. The system is comprised of the irradiation control sub-system (ICS) and the treatment interlock sub-system (TIS). The irradiation flow was implemented and monitored by firmware in ICS, with the benefit of low latency. Hardware based TIS conducts the calculation of interlock logics. The protection of patients and the machine from hazards could be guaranteed by TIS with high reliability. ICS is integrated into the main timing system, and ICS controls treatment-related sequence of the accelerator complex via the timing system. The function of switching treatment rooms is realized by hardware in the timing system. The design philosophy, the safety analysis and the design of critical modules are demonstrated in the paper.
