Abstract

The embodiment of the present invention discloses a protective ring control system for a medical accelerator, which includes a voltage and current source, at least two subsystems connected in parallel, a power line and a grounding line, and the first end of each subsystem is connected to the first end of the voltage and current source through a power line. One end; the second end of each subsystem is connected to the second end of the voltage and current source through a ground wire, wherein the voltage and current source is used to output a voltage signal or a current signal according to the operating state of the subsystem, and the operating state includes working state or fault state. Since the system uses a voltage and current source, the voltage and current source outputs a voltage signal or a current signal according to the operating state of the subsystem. When at least one subsystem fails, the voltage and current source outputs a current signal, and the voltage value obtained by each subsystem is the same. is 0V, so that each subsystem can sense the fault, which solves the problem in the prior art that every subsystem cannot sense the fault, and achieves the effect of improving the safety of the entire protection ring control system.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electronic circuits, in particular to a guard ring control system of a medical accelerator. Background technique [0002] In recent years, medical accelerators have been widely used in the preoperative or postoperative treatment of primary or secondary tumors in the head and neck, thoracic cavity, abdominal cavity, pelvic cavity, and limbs. In order to ensure the safety of medical accelerators, medical accelerators need to be connected to the protection ring control system through network communication. If some local medical accelerators fail, they will notify the relevant circuits of the protection ring control system to respond through hardware connections. [0003] In the prior art, in order to make the protection ring control system play a protective role, the voltage source is connected in series with the switches of each node, and the switch of each node controls a subsystem, a...
