Method, system, equipment and medium for controlling switching of particle accelerator operation modes Technical Field The present application relates to the field of particle accelerator control technologies, and in particular, to a method, a system, an apparatus, and a medium for controlling switching of a particle accelerator operation mode. Background Particle accelerator devices, in particular superconducting linear accelerators, are used as cores of modern large scientific devices, whose operation is extremely complex and precise. In the full life cycle of the accelerator, frequent switching between various operation modes such as injection debugging, beam optimization, full power operation, shutdown maintenance and the like is required. Each mode switching requires that the parameter states of all subsystems can be accurately and synchronously transited to target working conditions so as to ensure the stability of beam current, the physical safety of equipment and the smooth development of experimental tasks, which puts high requirements on the reliability and the intelligent level of operation control. In the prior art, the switching control of the particle accelerator operation mode mainly depends on two modes, and one mode is to take manual operation of operators as a main mode, namely the operators manually set and adjust parameters of mass equipment one by one according to different operation scene requirements, so that the switching control of the operation mode is realized. However, errors are easy to exist in manual setting, and it is difficult to ensure that all parameters are synchronously and accurately switched to a target state, so that the running stability of the particle accelerator is affected. The other mode is a static recovery mechanism based on parameter snapshot, which can only record and recover the target value of the parameter of the equipment, and is a static and isolated parameter configuration mode in nature, and although the pre-stored global parameter set at a certain moment can be written back to the equipment at one time to realize the rapid recovery of the target value, the configuration logic is limited to the simple storage and the calling of the parameter target value, the internal connection between the parameter setting, the safety constraint threshold and the operation access authority is cut off, the multi-dimensional dynamic linkage mechanism is lacked, and the safety behavior boundary and the personnel operation authority of the system cannot be automatically adjusted according to the current operation scene. In summary, the above two modes cannot realize accurate switching control of the operation mode of the particle accelerator, and it is difficult to meet the complicated operation requirement of the particle accelerator.
