Abstract

A remote control method of a ventilation system for a critical device is provided. The ventilation system comprises a normal ventilation system and an accident exhaust system. The remote control method comprises the following steps: detecting the operation state of a critical device, wherein the operation state of the critical device comprises normal operation of the critical device and abnormal operation of the critical device; when the critical device operates normally, receiving a first control instruction to start the normal ventilation system; and when the critical device is abnormal, receiving a second control instruction to stop running the normal ventilation system and start the accident exhaust system at the same time, and when the power of the critical device is larger than a first preset threshold value and / or the radiation dose is larger than a second preset threshold value, determining that the critical device is abnormal. According to the remote control method of the ventilation system for the critical device, remote control over the ventilation system can be achieved, workers are prevented from running back and forth between a machine room where the ventilation system is located and a control room, and operation convenience and working efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of critical devices, in particular to a remote control method and device for a ventilation system for critical devices. Background technique [0002] At present, the ventilation system used for critical devices (or zero-power reactors) is set far away from the control room. Before the experiment, the staff need to go to the computer room where the ventilation system is located to manually open the normal ventilation system. After the experiment is over, Staff then manually shut down the normal ventilation system. When an abnormality occurs in the critical device, the staff also need to manually activate the emergency exhaust system. In this way, it is inconvenient for the staff to control the ventilation system. Contents of the invention [0003] The embodiment of the present invention provides a remote control method and device for a ventilation system for a critical device. [0004] A remote control m...
