Abstract

The invention discloses a transport line equipment safety interlocking system for proton treatment. The transport line equipment safety interlocking system comprises an upper computer PC, a safety PLC, a switch and a transport line local controller. The switch is in communication connection with the upper computer PC and the safety PLC. The transport line local controller comprises an energy reducer control subsystem, a magnet control subsystem and a vacuum control subsystem. The PLC in the transport line equipment safety interlocking system adopts a safety PLC so that a SIL3 or SIL4 grade canbe realized; a byte operation speed in the PLC is at ns magnitude; and the PLC processes data transmitted by a lower system through an internal arithmetic unit, different interlocking logics can be performed according to different conditions provided by the upper computer PC, bottom-layer equipment of a transport line is selectively protected or shielded, and a response speed of the system transport line equipment safety interlocking system is increased.

Description

technical field

[0001] The invention relates to an interlocking system, in particular to a safety interlocking system for transport line equipment for proton therapy, and belongs to the application field of transport line equipment for proton therapy. Background technique

[0002] At present, accelerators have been widely used in many industries, especially in the field of proton therapy. The transport line not only has the function of transmitting beam current, but also can be used to adjust beam current.

[0003] The interlocking protection of transportation line equipment also adopts different methods and technical means. Most of them combine the safety interlocking system into the control system, use the same interface to display and integrate data collection into one, which leads to long data processing time of the whole system. The complexity of the system is large, and the advantages of equipment interlocking cannot be reflected; there are also a few that separate the...
