[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Before understanding the embodiments proposed in this application, it should be clear that in order to solve the problem that the deluge valve in the prior art proposed in the background technology often relies on manual operation during the closing and resetting process, which is not only inefficient, but also easily causes equipment damage or failure to reset correctly due to improper operation. In addition, the prior art lacks an automated reset mechanism and cannot quickly respond and restore the normal operation of the deluge valve. The present application proposes a deluge valve device with a reset mechanism and a method of use thereof applied to a deluge valve reset mechanism system, wherein the deluge valve reset mechanism system includes a plurality of monitoring sensors, and each monitoring sensor is used to obtain various monitoring data of the deluge valve. It should be clear that using monitoring sensors to obtain monitoring data of deluge valves is a mature technology and will not be described in detail here. In this embodiment, monitoring data is a general term for various monitoring parameters of deluge valves. For example, monitoring data can be any one or a combination of pressure, flow rate, and valve position. It should be clear that there are many types of data for monitoring deluge valves, which will not be listed one by one here, that is, in this embodiment, monitoring data can be any data related to deluge valve monitoring in the prior art.

[0041] It should be clear that, by installing a pressure sensor at a key position of the deluge valve system, the water pressure data in the pipeline is collected and recorded in real time to obtain monitoring data. The monitoring data is used to monitor the pressure state of the system and determine whether the opening or closing conditions of the deluge valve are met. In this embodiment, the monitoring data is used to monitor the pressure state of the system. Determining whether the opening or closing conditions of the deluge valve are met refers to setting the threshold of the pressure sensor. For example, if the pressure monitoring data threshold in the monitoring standard is 0.2-0.3MPa, and the monitoring pressure sensor detects that a certain pressure is lower than the opening threshold, the system automatically starts the deluge valve to release the water flow. If the monitoring data pressure threshold is greater than 0.2-0.3Mpa, the system will close the deluge valve to stop the water flow. In this embodiment, the monitoring data threshold of the monitoring standard can refer to international standards, national standards, or be provided by manufacturers or fire protection regulations, or can be set according to needs. Due to the large number of detection data types, in order to avoid redundancy, various detection data thresholds are not listed one by one here.

[0042] It should be clear that the flow sensor is used to monitor and record the water flow through the deluge valve in real time to obtain flow data, which is used to evaluate the fire extinguishing effect of the system and determine whether there is a pipe blockage problem. In this embodiment, the flow data of the deluge valve is calculated according to the "Design Specifications for Automatic Sprinkler Fire Extinguishing Systems". The nozzle flow calculation formula is:

[0043] Where q represents the nozzle flow rate, p is the nozzle working pressure, and k is the nozzle flow coefficient;

[0044] The design flow rate of the system should be determined according to the total flow rate of the sprinklers spraying water simultaneously within the effective area at the most unfavorable point. The calculation formula is:

[0045] Among them, Q s Design flow rate for the system, q i is the flow rate of the nozzle node within the effective area at the most unfavorable point, and n is the number of nozzles within the effective area at the most unfavorable point;

[0046] The actual monitored flow data is then compared with the design flow to assess whether the system can work as planned. If the actual flow is lower than the design flow, it indicates that there are performance problems in the system, such as pipe blockage, valve not fully opened, etc. The current flow data is compared with the historical data to analyze whether there are abnormal fluctuations. If the flow data continues to decline or fluctuates greatly, it indicates that blockages are gradually accumulating in the pipeline.

[0047] It should also be clear that when a fire occurs, it is necessary to observe and record the change of water flow over time. If the water flow increases rapidly and remains stable at the beginning of the fire, it indicates that the system responds quickly and the fire extinguishing effect is good. On the contrary, if the water flow is slow or fluctuates greatly, it may affect the fire extinguishing effect. In this embodiment, it is also necessary to monitor the flow data of a single nozzle to evaluate the working status of the nozzle. For example, if the flow of a nozzle is significantly lower than that of other nozzles, it indicates that the nozzle is blocked or damaged and needs to be repaired or replaced in time.

[0048] In an embodiment of the present application, the opening and closing state and position information of the deluge valve are obtained in real time through a valve position sensor, and the rotation angle or linear displacement of the valve is detected by the position sensor, and converted into an electrical signal that can be measured and transmitted. The sensor in this embodiment can be a rotary encoder, a linear displacement sensor or a Hall effect sensor, etc. When selecting a sensor, its measurement range, accuracy, durability and compatibility with the deluge valve, etc. need to be considered. In an embodiment of the present application, the selected sensor is installed on the deluge valve, and it is confirmed that the opening and closing state and position of the valve can be accurately measured. The installation position should be on the valve rotating shaft or linear moving part so that the movement of the valve can be directly sensed.

[0049] As can be seen from the foregoing, in the embodiment of the present application, according to the operating requirements and safety standards of the deluge valve system, the corresponding alarm threshold is set. When the monitored data exceeds the alarm threshold, the system automatically triggers the alarm, and the actual flow is set to be 80% lower than a certain proportion of the design flow as the lower limit alarm threshold. In order to detect possible blockage or insufficient water supply problems, according to the system design requirements, the minimum working pressure alarm threshold is set to ensure that the system can maintain sufficient pressure for fire extinguishing, and the highest working pressure alarm threshold is set to prevent the system from over-pressurizing and causing safety hazards. In this embodiment, since the design parameters and safety requirements of different systems are different, the alarm threshold data in this embodiment can be determined according to the foregoing or the actual situation of the system. Based on the water flow state in the pipeline, the water source terminal caused by pipeline blockage, valve failure, etc. is prevented. The water flow alarm threshold is calculated based on factors such as the system design flow, the nozzle water spraying demand and the pipeline diameter. When the water flow in the pipeline is lower than a certain proportion of the system design flow of 80%, the alarm should be triggered.

[0050] In this embodiment, according to the core logic formula algorithm, the collected data is processed to determine whether a reset operation needs to be performed, and a reset instruction is generated. As can be seen from the foregoing, by introducing a reset control algorithm based on state monitoring, the collected sensor data is obtained, the difference between the current state of the valve and the expected state is calculated, and the reset instruction is generated accordingly. The expected state threshold can be 50% for the specific opening value of the adjustable valve, and the system pressure range for maintaining a specific pressure is 4-6bar. In the embodiment of the present application, according to the system requirements, the expected state can be a specific flow value or flow range. In the embodiment of the present application, for some parameters that can be directly quantified, the difference or percentage deviation between the actual value and the expected value can be directly calculated. If the state is jointly determined by multiple parameters, a weight can be assigned to each parameter, and then the total weighted difference is calculated. In some cases, a more complex model may be required to comprehensively evaluate the state difference, for example: using a machine learning model, and no complex model is listed here one by one.

[0051] It should be clear that in the embodiment of the present application, the pre-processed data is processed according to the core logic formula algorithm, and it is checked whether the fire extinguishing signal is valid, whether the time delay has been satisfied, and whether there is a manual reset signal to obtain the logic judgment result. First, it is necessary to clarify the specific content of the core logic formula algorithm. In this embodiment, it is designed through safety regulations, such as weighting, threshold comparison, logical operation, etc. of multiple sensor input signals. If the temperature detected by the temperature sensor exceeds the set threshold and the smoke sensor also detects smoke, it is regarded as a fire alarm. Before applying the core logic formula, confirm that the fire extinguishing signal comes from a trusted sensor and device. If the fire extinguishing signal is a continuous signal, such as an electric The voltage or current value is compared with the preset effective threshold. If the signal value is within the effective range, the signal is considered valid. If the fire extinguishing signal is a discrete signal, such as a switch state, it is directly checked whether it is in an activated state. In this embodiment, different fire extinguishing equipment may have different activation voltage or current requirements. In order to ensure the reliability and safety of the system, a certain safety margin is usually added to the activation value required by the equipment. Taking into account possible environmental factors such as electromagnetic interference and power supply fluctuations, the threshold setting needs to have a certain anti-interference ability. Therefore, in the embodiment of the present application, the preset threshold is not a fixed value, but is set according to safety specifications and usage requirements. For example: If the fire extinguishing equipment is required to be activated when the voltage reaches 12V, then the preset threshold may be set to a value slightly higher than 12V, such as 12.5V, to ensure that it can still be reliably activated when there is a slight power supply fluctuation.

[0052] It should be clear that in this embodiment, signal values ​​below a certain lower limit (such as below the safety threshold) or above a certain upper limit (such as above the equipment damage risk threshold) are considered invalid. These values ​​indicate sensor failure, power supply problems or environmental abnormalities. Signal values ​​near the preset threshold are considered valid. In this interval, the system decides whether to trigger the fire extinguishing operation based on specific logical judgment rules. The signal value must remain above the threshold for a certain period of time of more than 1 minute to ensure that the signal is not a short-term interference or false alarm. In the valid interval, there may be a narrower interval. When the signal value reaches or exceeds this interval, the system will immediately trigger the fire extinguishing operation. In the embodiment of the present application, multiple sensors can also detect abnormal signals at the same time, and verify each other through logical judgment to improve the accuracy of triggering the fire extinguishing operation. In some cases, the triggering of the fire extinguishing system may also need to rely on other linkage trigger signals. For example: in a gas fire extinguishing system, when the fire detector detects abnormal conditions such as flames, smoke or high temperature, it will send a fire signal as the first linkage trigger signal. After receiving this signal, the system may start the fire sound and light alarm for early warning. Subsequently, when a second linkage trigger signal is received (such as the temperature-sensitive fire detector adjacent to the fire detector that initially alarmed also detects an abnormality), the system will confirm the fire situation and send out a linkage control signal to trigger a fire extinguishing operation.

[0053] As can be seen from the foregoing, a reset instruction is generated according to the result of the logical judgment, and the reset instruction is passed to the execution control module. After receiving the reset instruction, the execution control module controls the rain shower valve to perform the reset operation. In the embodiment of the present application, according to the core logic formula algorithm described above, according to the input of the system, such as sensor data, button status and time conditions, logical judgment is performed. These inputs are connected to the microcontroller or PLC through a physical interface (such as a digital or analog input port), and a logical judgment program is written in a programming language. Then, according to the system requirements, the judgment conditions are set. For example: the fire detection sensor does not detect the fire source, the manual reset button is pressed, etc., in this embodiment, they are not repeated one by one.

[0054] It should be clear that in this embodiment, during the logic judgment, once it is determined that a reset is required, a reset instruction is generated. This instruction can be a simple digital signal, such as: a high level or a low level, a setting of a flag bit, or a communication message of a specific format. In the logic judgment program, the result of the reset condition being satisfied is converted into a corresponding signal or instruction. The reset instruction needs to be passed to the execution module, which can be achieved through a physical connection or a communication protocol. If a microcontroller is used, the reset signal can be directly connected to the input end of the execution control module through the GPIO pin. If the system is more complex, a communication protocol can be used for data transmission, and the code is written to encapsulate the reset instruction into a data packet, which is sent to the execution control module through the selected communication protocol. After the execution control module receives the reset instruction, it needs to parse the instruction and control the shower valve to perform a reset operation accordingly. If the instruction is received through the communication protocol, the execution control module needs to first parse the data packet and identify the reset instruction. According to the parsed reset instruction, the execution control module sends a control signal to the actuator of the shower valve, such as a solenoid valve, through the GPIO output or other control interface. After receiving the control signal, the actuator of the shower valve performs a reset operation, such as closing the solenoid valve. In the application embodiment, in order to ensure the successful execution of the reset operation, a feedback mechanism is added to the system. For example, the state of the deluge valve is detected by a sensor, and the state information is fed back to the control system for monitoring and further logic processing.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the attached embodiments and their equivalents.
