It can be understood that when the fire valve is not successfully opened and is judged not to be in the safe working state, the judging unit can acquire the environmental information of the fire valve, and correct the adjusted valve torque according to the environmental information so as to obtain the corrected valve torque. The environment information comprises temperature information, humidity information and air flow rate. The valve is in a wet and dark environment, valve corrosion is easy to cause, the valve structure is easy to damage, and if the valve is deformed or corroded, the valve cannot be normally opened by the adjusted valve torque, so that the valve torque is required to be increased. However, if the torque is too large, the valve is easy to damage, so that irreversible loss is caused, and therefore, the valve torque is adaptively adjusted according to the environmental information of the valve, so that the valve torque is ensured to be in a safe range, and the valve can be opened conveniently and can be prevented from being damaged. The valve can not be normally opened by the corrected torque, so that the valve can not be normally used, and personnel are required to be reminded to replace and dismantle the valve, and red early warning is sent. If the corrected torque can open the valve to indicate that the valve has rust damage, but can be reused, yellow early warning information is sent out to remind personnel to maintain so as to prolong the service life of the valve and reduce the maintenance cost.
In the embodiment, the acquisition unit acquires the real-time pressure and flow information of the pipeline and adjusts the real-time pressure and flow information according to a preset value so as to ensure accurate selection and adjustment of the valve torque. The pipeline state is monitored in real time and dynamically adjusted, so that the valve is ensured to operate under proper torque, and the responsiveness and performance of the system are improved. The judging unit judges whether the fire valve is in a safe working state according to the opening state of the valve. Ensuring that the valve operates within the normal operating range and providing an accurate assessment of the state of the system. The early warning unit tries to open the fire valve again according to the corrected valve torque, and sends early warning information according to the opening state. Yellow early warning information indicates that the valve was successfully opened but needs to be noted, and red early warning information indicates that the valve was not successfully opened and has problems. The early warning information provides real-time state feedback, and helps operators to take measures in time to ensure the safety and reliability of the system. When the fire valve is successfully opened, judging whether maintenance is needed according to comparison of the valve water yield and the preset water yield. This helps to discover valve failure or anomalies early, improving maintenance efficiency and system reliability.
