The invention discloses an electric power intelligent monitoring system based on multi-device cooperative linkage and an operation and maintenance method, and belongs to the technical field of electric power intelligent monitoring and operation and maintenance. Radiation data and historical decay records are collected through a sensor, a linear regression algorithm is adopted to fit and establish an energy spectrum purity attenuation model, and the dose loss proportion is calculated in real time; carrying out dynamic compensation on beam intensity and irradiation time based on the proportion, fusing real-time dose monitoring data by utilizing a Kalman filtering algorithm, and optimizing a beam intensity value to suppress noise interference; the irradiation time is further adjusted according to whether the dose loss exceeds a threshold value or not, and a dynamic compensation combination is formed; the effectiveness of the combination in each stage of the source life cycle is verified through the simulation module, and the verified compensation parameters are updated to the control system in real time, so that closed-loop regulation and control are realized. According to the invention, the whole process of dose output in the irradiation process is accurately and stably controlled, and the consistency and reliability of the irradiation process are remarkably improved.

The present application relates to the technical field of radiotherapy control, and discloses a treatment control method and system for AB-BNCT. The method comprises the following steps: sending a beam-out condition verification request and a beam-out safety verification request in response to a beam-out request; sending a beam-out button display instruction after receiving the pass results, so that the beam-out button is displayed based on a preset state; monitoring main real-time beam data in real time in response to a state change of the beam-out button; determining a main real-time neutron absorption dose based on the main real-time beam data; and sending a beam control instruction to an accelerator based on the main real-time neutron absorption dose and a target neutron absorption dose, so that the accelerator controls the beam in response to the beam control instruction. By comparing the real-time dose with the target dose, the treatment is continued or stopped, and the accuracy of the treatment and the safety of the patient are ensured. The present application solves the technical problems of low safety and dose verification lag in the existing AB-BNCT treatment, and improves the safety and efficiency of AB-BNCT treatment.
