A gas valve is an important component in a gas supply system for controlling the flow of gas. The valve may be operated manually or automatically and its main function is to open, close or regulate the flow of gas through the conduit.
For manual gas valves it is necessary for the user or technician to open or close himself. Valves of this type are commonly used in domestic gas appliances, such as gas burners or water heaters.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention provides a control method of intelligent household gas valves based on WIFI, which comprises the following steps:
s101, periodically acquiring the gas flow through a gas valve by a system;
s102, judging whether the gas flow is greater than 0 by the system;
s103, if the gas flow is greater than 0, the system acquires the temperature of the gas stove in real time in a detection period;
s104, comparing the temperature of the gas range with a first threshold value by the system;
s105, if the temperature of the gas cooker is smaller than a first threshold value, generating a gas leakage signal by the system, wherein the gas leakage time and the gas leakage warning instruction;
s106, the system sends the gas leakage signal to a cloud;
s107, the system executes the leakage warning instruction of the gas leakage signal so as to control the alarm to warn.
Referring to fig. 1, in the present embodiment, the system periodically measures the flow of gas through the gas valve using a sensor.
When the system detects that the gas flow is greater than 0 (namely the gas is used), the system automatically starts to monitor the temperature of the gas stove in real time in the detection period.
The system compares the gas range temperature monitored in real time with a preset first threshold value. If the gas range temperature is below a first threshold (indicating a leak in the range), the system determines that a leak has occurred and generates an alarm signal.
Once the gas leak signal is generated, the system sends it to the cloud.
If the gas range temperature is below a first threshold, the system identifies a leak condition and generates a gas leak signal.
The leakage signal is sent to the cloud and activates an alarm in the home through the system, and at the same time, the user is notified through a mobile application or a short message. So as to remind users of gas leakage and avoid damage to personal and property caused by gas leakage.
The control method of the intelligent household gas valve based on the WIFI provides a comprehensive safety monitoring and quick response mechanism, and the risk in the gas use process is greatly reduced.
The gas flow sensing probe is arranged on the inner wall of the valve pipeline to sense the gas flow.
The first infrared sensor is arranged on the wall and towards the gas stove, and the first infrared sensor is used for monitoring the temperature of the gas stove.
The first threshold is a manually preset range of values.
The system uses a sensor to periodically measure the flow of gas through the gas valve. This periodic monitoring is in seconds or minutes, ensuring continuous monitoring.
The system can continuously monitor the gas flow, discover any tiny leakage or abnormal flow in time, and can keep alert even in a non-use state.
When the system detects that the gas flow is greater than 0 (i.e. the gas is used), it automatically starts to monitor the temperature of the gas cooker in real time.
Real-time temperature monitoring is ensured in the case of gas being used, so that anomalies are immediately detected in the case of gas burner actually extinguishing but gas still flowing.
The system compares the gas range temperature monitored in real time with a preset first threshold value. If the gas burner temperature is below the threshold (indicating a leak in the burner), the system determines that a leak has occurred and generates an alarm signal.
Normal gas use and potential leakage conditions can be accurately distinguished, so that a safety response is automatically triggered under the condition of no supervision.
Once the gas leak signal is generated, the system sends it to the cloud. Such as Wi-Fi or cellular networks.
By transmitting the alert signal to the cloud, the system can trigger not only the home alert system, but also notify a remote user or emergency services. Timely response is ensured, and real-time update can be obtained even if the user is not at home.
In an embodiment of the invention, the method further comprises:
if the gas flow is greater than 0, acquiring the gas flow of the gas valve in real time in a detection period;
s108, uploading the gas flow of the gas valve obtained in real time to the cloud by the system.
In this embodiment, when the system detects a gas flow greater than 0, indicating that gas is being used, the system will immediately begin to monitor the gas flow at the gas valve in real time.
The real-time monitoring ensures continuous data recording in the gas use process, and allows the system to capture any abnormal flow change in time, thereby improving the response speed to potential problems.
And uploading the monitored gas flow data to the cloud. The data is sent to the cloud server through a built-in wireless communication module (such as Wi-Fi or cellular network).
Cloud data storage can track and analyze long-term data, and simultaneously provides historical data references for users and maintenance personnel. The remote monitoring and control are allowed, and the flexibility and the reliability of the system are enhanced.
Not only improves the family safety, but also enhances the capability of data management and remote control, thereby ensuring safer, more efficient and more convenient gas use.
In an embodiment of the invention, the method further comprises:
and S109, if the gas flow is equal to 0, the system waits for the acquisition of the gas flow of the gas valve in the next period.
In this embodiment, the system periodically detects the gas flow rate of the gas valve.
When the system detects that the gas flow is equal to 0, it recognizes that no gas is currently in use and no leakage occurs.
In this state, the system shifts to a power saving periodic detection mode.
In this mode, the system performs gas flow detection at preset longer intervals, for example once per hour.
If a change in gas flow rate from 0 is detected in a subsequent detection cycle, the system will readjust its mode of operation in response to this change.
The system effectively reduces the energy consumption when no gas is used on the premise of not sacrificing the safety, so that the whole operation is more efficient and economical.
In an embodiment of the invention, the method further comprises:
if the gas flow is greater than 0, acquiring the temperature of the gas range and the real-time gas flow in real time in a detection period, and generating a combustion temperature difference value according to the temperature of the gas range and the real-time gas flow;
s203, the system compares the combustion temperature difference value with a second threshold value;
s204, if the combustion temperature difference value is smaller than the second threshold value, generating a gas combustion abnormal signal;
s205, sending the gas combustion abnormal signal to a cloud.
In an embodiment of the present invention, if the gas flow is greater than 0, the step of acquiring the gas range temperature and the real-time gas flow in real time in the detection period and generating the combustion temperature difference according to the gas range temperature and the real-time gas flow further includes:
s201, calculating a corresponding gas combustion temperature according to the real-time gas flow by the system;
s202, the system calculates the difference between the temperature of the gas range and the corresponding gas combustion temperature to obtain a combustion temperature difference.
Referring to fig. 1 to 2, in the present embodiment, when the gas flow rate is greater than 0, the system monitors both the gas flow rate and the temperature of the gas range in real time.
The system predicts the theoretical temperature due to combustion according to the real-time gas flow, and compares the theoretical temperature with the actual gas range temperature, so as to calculate the combustion temperature difference.
The calculated combustion temperature difference is compared with a set second threshold value. The second threshold is used to determine whether combustion is normal.
If the combustion temperature difference is less than a second threshold, indicating that the gas may not be fully combusted, the system generates a gas combustion anomaly signal.
The anomaly signal is sent to the cloud for remote monitoring and data analysis.
By monitoring and analyzing the gas flow and the temperature of the gas cooker, the system can accurately judge whether the gas is completely combusted.
If the gas is not completely burned, which may be due to leakage in the pipe between the gas valve and the gas burner, the system can recognize this risk in time and give an alarm.
The system can timely find the condition that the gas is not completely combusted, so that possible gas leakage is prevented in advance, and the safety of household gas use is enhanced.
The existing detection method can only detect the gas content of the air in idle time (namely, in a state that the gas is not used), but the problem of gas combustion exists in the using process (in the using process of the gas cooker), so that the gas exists in the air, and the problem of abnormal detection is caused.
In the embodiment, the temperature generated by theoretical gas combustion is calculated by adopting real-time gas flow, then the difference value caused by temperature loss is subtracted to obtain the temperature range generated by theoretical gas combustion, a second threshold range is obtained, and the temperature generated by the gas stove is compared with the second threshold range, so that whether leakage occurs in a connecting pipeline between the gas stove and the gas valve is obtained.
The system predicts the theoretical temperature due to combustion according to the real-time gas flow, and compares the theoretical temperature with the actual gas range temperature, so as to calculate the combustion temperature difference.
The calculated combustion temperature difference is compared with a set second threshold value. The second threshold is used to determine whether combustion is normal.
For example: the gas valve is supplied at a flow rate of 2.5 square/hour when fully opened, the theoretical combustion temperature is between 2000 ℃ and 2200 ℃, the actual combustion temperature is between 1000 ℃ and 1600 ℃ due to the influence of factors such as the design of the gas cooker, the combustion efficiency, the mixing ratio of air and gas and the like, and the second threshold range is 600 to 1000.
The second threshold is a manually set value and is a difference range between actual gas combustion and theoretical gas combustion.
In an embodiment of the invention, the method further comprises:
s301, generating an alarm signal and controlling an alarm to warn;
s302, detecting whether a closing valve is closed within a threshold time;
s303, if the valve is not closed at the end of the threshold time, generating a valve closing signal;
and S304, sending the valve closing signal to a gas valve, and executing the valve closing signal by an MOS tube on the gas valve, wherein the MOS tube on the gas valve drives a driving motor on the gas valve to move so as to drive a closing valve on the gas valve to close a gas channel of the gas valve.
In an embodiment of the invention, the method further comprises:
s305, after the gas channel of the gas valve is closed by the closing valve, detecting whether a user approaches in a first range;
s306, if the user approaches, detecting whether a valve opening signal is received;
and S307, if the valve opening signal is received, the valve opening signal is sent to an MOS tube on the gas valve, the MOS tube on the gas valve executes the valve opening signal, and the MOS tube on the gas valve drives a driving motor on the gas valve to move so as to drive a closing valve on the gas valve to open a gas channel of the gas valve.
Referring to fig. 1 to 3, in the present embodiment, when a gas leak or other risk is detected, the system automatically generates an alarm signal and activates an alarm while detecting whether the valve is closed. If the valve is not closed within the preset time, the system automatically generates a valve closing signal.
After the MOS tube on the gas valve receives the valve closing signal, the motor on the gas valve is driven to close the gas channel.
After the valve is closed, the system monitors whether a user approaches, receives a valve opening signal sent to the system by a button on a user operation terminal device or the valve, and re-opens the gas valve through the MOS tube when the valve opening signal is received.
The system ensures that safety measures are taken quickly and automatically in case of emergency, while also allowing the user to re-start the gas supply after confirming safety.
The gas valve can be automatically closed and alarmed in time, so that emergency situations can be rapidly handled, and the expansion of accidents is prevented.
The use of the MOS tube improves the response speed and reliability of valve operation, and ensures that the gas supply can be effectively cut off at key time.
The user can re-enable the gas supply under the condition of ensuring safety, thereby providing flexibility and convenience of operation.

It will be appreciated by those skilled in the art that the structure shown in fig. 5 is merely a block diagram of some of the structures associated with the present application and is not limiting of the computer device to which the present application may be applied, and that a particular computer device may include more or fewer components than shown, or may combine certain components, or have a different arrangement of components.
In one embodiment, a computer-readable storage medium is provided, storing a computer program which, when executed by a processor, causes the processor to perform the steps of:
periodically acquiring the gas flow passing through a gas valve;
judging whether the gas flow is greater than 0, if the gas flow is greater than 0, acquiring the temperature of the gas range in real time in a detection period, comparing the temperature of the gas range with a first threshold value, and if the temperature of the gas range is less than the first threshold value, generating a gas leakage signal, and generating a gas leakage time and a leakage warning instruction;
sending the gas leakage signal to a cloud;
and executing the leakage warning instruction of the gas leakage signal to control an alarm to warn.
Referring to fig. 5, the system periodically measures the flow of gas through the gas valve using a sensor.
When the system detects that the gas flow is greater than 0 (namely the gas is used), the system automatically starts to monitor the temperature of the gas stove in real time in the detection period.
The system compares the gas range temperature monitored in real time with a preset first threshold value. If the gas range temperature is below a first threshold (indicating a leak in the range), the system determines that a leak has occurred and generates an alarm signal.
Once the gas leak signal is generated, the system sends it to the cloud.
If the gas range temperature is below a first threshold, the system identifies a leak condition and generates a gas leak signal.
The leakage signal is sent to the cloud and activates an alarm in the home through the system, possibly notifying the user through a mobile application or a short message. So as to remind users of gas leakage and avoid damage to personal and property caused by gas leakage.
The control method of the intelligent household gas valve based on the WIFI provides a comprehensive safety monitoring and quick response mechanism, and the risk in the gas use process is greatly reduced.
