This invention relates to a constant pressure control system for an optical cavity based on pump-valve coordination and water immersion sensing, and its active protection method. Belonging to the fields of precision instrument control and industrial automation, the system integrates an electronically controlled proportional valve and an air pump through a pump-valve coordinated pressure control unit. It dynamically adjusts the intake and exhaust flow rates based on an adaptive PID algorithm and a coordinated allocation function, achieving high-precision, rapid, bidirectional adjustment of the optical cavity pressure. Simultaneously, it employs a dual environmental sensing unit including visual perception and capacitive liquid level sensing, which executes constant pressure control and active anti-intrusion monitoring in parallel through an intelligent coordinated control unit. When visual detection identifies a risk of water intrusion, the system proactively limits the pump speed; when the capacitive sensor detects liquid water intrusion, it immediately executes an emergency shutdown. This solves the problem of difficulty in coordinating pressure control and safety assurance in traditional technologies, achieving a unified approach of long-term precise constant pressure and active contamination protection, significantly improving the system's reliability, safety, and intelligence level under complex operating conditions.

The application provides a tab page data synchronization method and device and electronic equipment, and relates to the field of coordination computing and distributed coordination. In the application, concurrent operation conflict detection is performed on initial state change operations respectively initiated by a target object within a set time range for any two active tab pages in a browser to obtain a conflict detection result. If the conflict detection result indicates that the two initial state change operations have concurrent operation conflicts, a target conflict resolution strategy matching the two initial state change operations is selected from a plurality of candidate conflict resolution strategies. Operation conversion is performed on the two initial state change operations based on the target conflict resolution strategy to obtain a target state change operation. The target state change operation is applied to the any two active tab pages respectively, so that the any two active tab pages are synchronized with a tab page state corresponding to the target state change operation. In this way, complex concurrent operation conflicts can be effectively handled.
