Problems solved by technology

[0002] In the related technical solutions, the container protection scheme usually adopts a single electronic control scheme to realize the container protection. Taking the pressure vessel protection scheme as an example, under normal circumstances, it is necessary to install a pressure relief valve controlled by a drive circuit on the pressure pipeline of the pressure vessel. When the pressure is too high, the pressure relief valve will act to release the pipeline pressure, but the control process of the pressure relief valve will involve the action of the circuit connected to the drive circuit, and the circuit connected to the drive circuit will There will be actions of electronic devices such as semiconductors and / or relays. Since electronic devices such as semiconductors and / or relays are unreliable devices, the reliability of existing container protection schemes is low and cannot meet the current reliability requirements. Causes pressure relief valves to fail to release pressure accurately, resulting in less reliable container operation
