In the prior art, due to the large number of pressure vessels, workers are required to operate and handle different pressure vessels in turn, which is inconvenient to control multiple pressure vessels at the same time, and the control effect is not ideal.

[0003] For example, patent publication number CN201487198U is specifically an intelligent interlock safety pressure vessel control system that uses a human-machine interface dialogue to set the interlocking and opening of the pressure vessel. It includes a pressure vessel and an electric control box. A pressure sensor and a temperature sensor are provided on the upper end of the pressure vessel, and the signal output ends of the pressure sensor and the temperature sensor are connected to the signal input end of the electric control box; the opening and closing between the end cover and the pressure vessel body in the pressure vessel adopts a pneumatic mechanism, and a proximity switch that cooperates with the pneumatic mechanism is provided on the pressure vessel body, and the signal output end of the proximity switch is connected to the signal input end of the electric control box, and the signal input end of the pneumatic mechanism is connected to the signal output end of the electric control box; a safety interlock actuator is provided between the end cover and the pressure vessel body, and a proximity switch that cooperates with the safety interlock actuator is provided on the pressure vessel body, and the signal output end of the proximity switch is connected to the signal input end of the electric control box. Advantages: one-button operation, real-time safety monitoring, automatic recording, safe opening and closing are achieved. However, there is a problem that due to the large number of pressure vessels, the staff needs to operate and handle different pressure vessels in turn, which is inconvenient to control multiple pressure vessels at the same time, and the control effect is not ideal.

[0004] For example, patent publication number CN118896249A is specifically a quick-opening pressure vessel control system, which involves the technical field of pressure vessels. The system includes: an initialization configuration module to obtain the target pressure vessel, install and configure the system functional components, a control strategy configuration module to formulate a control strategy based on the initialization results and the characteristic parameters of the target pressure vessel, combined with the target scene requirements, and a user authentication module to interact with the user end, obtain the user's biometric authentication information for compliance authentication, and release the safety lock of the target pressure vessel based on the authentication result. The state update module collects user operation instructions through the user end, calls the system functional components for monitoring and collection, and obtains the key discrimination index data of the target pressure vessel. The decision control module makes a judgment decision on the key discrimination index data according to the control strategy, outputs the pressure vessel response instruction and executes the control operation, thereby achieving the technical effect of improving the control automation level and improving the safety of operation. However, there is a problem that due to the large number of pressure vessels, the staff needs to operate and process different pressure vessels in turn, which is inconvenient to control multiple pressure vessels at the same time, and the control effect is not ideal.
