SINAP v2 timing system was implemented in the timing system of Shanghai Proton Therapy Project. The timing system in Shanghai Proton Therapy Project is required not only to generate operation sequence for medical proton synchrotron, but also to realize irradiation flow for beam delivery system. For these purposes, the firmware of SINAP v2 timing system is redesigned to satisfy both event code sequenced broadcasting to generate operation sequence and bidirectional event code transmit to realize irradiation flow. Thanks of the hardware advantage of SINAP v2 timing system, the event receiver (EVR) could transmit event code to event generator (EVG) and then broadcast to timing network by bidirectional transmit ability. By this design, the EVR installed in treatment room has ability to send event code to timing network to stop/start beam during slow extraction. The architecture of the timing system in Shanghai Proton Therapy Project is presented in the paper. The risk analysis is also described in detail.
