Interlocking control method, device, system and radiotherapy equipment

Abstract

The invention relates to an interlocking control method, a device, a system and radiotherapy equipment, and belongs to the field of radiotherapy. The method comprises the following steps of receivingand detecting a state signal for indicating the position of a treatment bed and / or the position of a shielding door, and controlling the movement of the treatment bed or the shielding door interlockedwith the state signal according to the detection result. Therefore, even if a controller in the interlocking control device breaks down to trigger a driver by mistake, a protection module can also control the movement of the treatment bed or the shielding door according to the state signal for indicating the position of the treatment bed and / or the position of the shielding door. As a result, thecondition that when the controller breaks down to trigger the driver by mistake, the driver is driven to work by mistake to cause the mis-operation of the treatment bed or the shielding door and makethe treatment bed or the shielding door in a dangerous situation can be avoided. The safety and the reliability of the radiotherapy equipment are improved.

Description

technical field [0001] The invention relates to the field of radiotherapy, in particular to an interlock control method, device, system and radiotherapy equipment. Background technique [0002] Radiation therapy equipment is an instrument that uses radiation produced by radioactive isotopes to treat lesions in the human body. In order to ensure the safety and reliability of human body treatment, the control system in the equipment has high requirements. [0003] In the related art, the control device of the radiotherapy equipment generally consists of a control module, a driving module and a detection module. During the treatment process, the control module can drive the screen door to open through the drive module according to the position signal of the treatment bed fed back by the detection module; when the screen door is fully opened, the control module can drive the The module drives the treatment couch to move into the screen door. [0004] However, when the control...
