Background
The combustible gas becomes an indispensable part of energy sources required by daily life of people, and people can use the combustible gas for cooking and heating. However, leakage of the combustible gas brings immeasurable loss to lives and properties of people, so in order to protect lives and properties of people, a gas alarm is usually installed in a home so that the gas alarm can be timely given out when the combustible gas leaks. The gas alarm usually detects the concentration of the combustible gas in the surrounding environment through a gas sensor, then compares the detected concentration of the combustible gas with a preset concentration threshold value, and when the concentration of the combustible gas exceeds the preset concentration threshold value, the gas alarm sends out an alarm signal.

Therefore, if the gas alarm detects that the local high-concentration gas exists around the gas alarm, the gas alarm alarms, and false alarm is caused, so that people are unnecessarily panicked, and therefore, the false alarm of the gas alarm needs to be reduced.

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.
In the prior art, when people use fuel gas, the ignition device for igniting the fuel gas usually has the condition that ignition cannot be performed for a short time, so that a small amount of fuel gas which is not combusted leaks to form local high-concentration fuel gas, and the local high-concentration fuel gas can be quickly dissipated in practice, and no potential safety hazard exists. But when the local high-concentration fuel gas is detected by the fuel gas alarm, the fuel gas alarm is triggered to alarm. The false alarm is caused, and people are unnecessarily panicked, so that the false alarm of the gas alarm is required to be reduced.
In order to solve the problems in the prior art, the embodiment of the invention provides a gas alarm method, a device, electronic equipment and a storage medium, so as to reduce false alarm of a gas alarm.
Next, a gas alarm method according to an embodiment of the present invention will be described, as shown in fig. 1, which is a flowchart of a first implementation of a gas alarm method according to an embodiment of the present invention, where the method may include:
s110, acquiring a first moment of alarm request information generated by a gas alarm based on a gas concentration signal and a second moment of an ignition event generated by an ignition device, wherein the ignition device is used for igniting combustible gas for life through ignition, and the ignition event is generated by the ignition device during ignition;
S120, determining whether to generate an alarm signal for representing gas leakage or not based on the difference between the first moment and the second moment;
and S130, when the generation of the alarm signal is determined, the gas alarm is instructed to generate the alarm signal.
In some examples, the gas alarm and the ignition device are both intelligent devices, i.e. the gas alarm can detect gas, can perform subsequent processing based on gas concentration, and can send the gas concentration to a back-end device in communication connection with the gas alarm. For example, a gas alarm may generate an alarm event upon an alarm request message generated based on a gas concentration signal and transmit the alarm event to a back-end device communicatively coupled to the gas alarm.
The gas alarm can generate a gas concentration signal when gas with any concentration is collected, and then generate alarm request information based on the gas concentration signal, or generate alarm request information when the gas concentration represented by the gas concentration signal is greater than a preset gas concentration threshold value.
The preset gas concentration threshold value is a value empirically set in advance, and may be set to be low, for example, 1%, or may be set to be high, for example, 5%, without being limited thereto.
The ignition device may generate an ignition event upon ignition and transmit the ignition event to a backend device in communication with the ignition device. The ignition device can be an intelligent gas stove or an intelligent wall-mounted stove and other devices. The ignition device may take the moment of ignition as the moment of generating the ignition event when generating the ignition event.
In some examples, the gas alarm and the ignition device may be connected to each other via a local area network, or may be connected to the same IOT (Internet Of Things ) platform. The gas alarm and the ignition device can be located at different positions, and the installation position of the gas alarm can be determined based on the installation requirement of the gas alarm in the prior art, which is not described herein.
In still other examples, a gas alarm method according to embodiments of the present invention may be applied to IOT platforms, gas alarms, and ignition devices.
When the method is applied to the IOT platform, the gas alarm sends an alarm event to the IOT platform, and the ignition device also sends an ignition event to the IOT platform, so that the IOT platform can acquire the alarm event sent by the gas alarm and the ignition event sent by the ignition device. The IOT platform may then obtain a first time of an alarm request message generated by the gas alarm based on the gas concentration signal from the alarm event and a second time of an ignition event generated by the ignition device from the ignition event.
When the method is applied to the gas alarm, the ignition device can send the ignition event to the gas alarm, the gas alarm can acquire the ignition event sent by the ignition device and the alarm event generated by the gas alarm, acquire the first moment of alarm request information generated by the gas alarm based on the gas concentration signal from the alarm event, and acquire the second moment of the ignition event generated by the ignition device from the ignition event.
When the method is applied to the ignition equipment, the gas alarm can send an alarm event to the ignition equipment, the ignition equipment can acquire the alarm event sent by the gas alarm and the ignition event generated by the gas alarm, acquire a first moment of alarm request information generated by the gas alarm based on a gas concentration signal from the alarm event, and acquire a second moment of the ignition event generated by the ignition equipment from the ignition event.
After the equipment applying the gas alarm method provided by the embodiment of the invention acquires the first moment and the second moment, whether to generate an alarm signal representing gas leakage or not can be determined based on the difference value between the first moment and the second moment in order to reduce false alarm; and when the generation of the alarm signal is determined, the gas alarm is instructed to generate the alarm signal for alarming. When it is determined that the alarm signal is not generated, the gas alarm may be instructed not to generate the alarm signal.
It can be seen that, in the embodiment of the present invention, by determining whether to generate the alarm signal for characterizing the gas leakage based on the difference between the first time and the second time, the alarm signal can be generated by integrating the condition of the alarm request information generated by the gas alarm based on the gas concentration signal and the condition of ignition, so that the problem of false alarm caused by generating the alarm signal based on the gas only can be effectively reduced.
In some examples, the first time may be one or more; similarly, the second time may be one or more.
When the first time and the second time are both one, on the basis of a gas alarm method shown in fig. 1, the embodiment of the present invention further provides a possible implementation manner, as shown in fig. 2, which is a flowchart of a second implementation manner of a gas alarm method in the embodiment of the present invention, where the method may include:
s210, acquiring a first moment of alarm request information generated by a gas alarm based on a gas concentration signal and a second moment of an ignition event generated by an ignition device, wherein the ignition device is used for igniting combustible gas for life through ignition, and the ignition event is generated by the ignition device during ignition;
S220, determining to generate an alarm signal when the first moment is positioned in a preset time period before the second moment;
s230, determining that no alarm signal is generated when the first moment is outside a preset time period before the second moment or when the second moment is before the first moment;
s240, when the generation of the alarm signal is determined, the gas alarm is instructed to generate the alarm signal.
In some examples, the first time of the alarm request information generated by the gas alarm based on the gas concentration signal may be the same as or different from the second time of the ignition event generated by the ignition device.
When the first time is the same as the second time, since the gas alarm and the ignition device are located at different positions, it can be explained that when the ignition device ignites, gas has spread from the gas outlet of the ignition device to the mounting position of the gas alarm, and at this time, it can be determined that an alarm signal is generated.
When the first time is different from the second time, the first time may be located before the second time or may be located after the second time, if the first time is located before the second time, a potential safety hazard may exist when the ignition device ignites, for this reason, when the first time is located within a preset time period before the second time, in order to avoid a risk that the gas concentration is still higher in a period of time after the alarm request information generated by the gas alarm based on the gas concentration signal, the generation of the alarm signal may be determined when the ignition event is acquired in the period of time; that is, when the first time is within a preset time period before the second time, the generation of the alarm signal is determined.
In some examples, upon determining to generate an alarm signal, the gas alarm may be instructed to generate an alarm signal and instruct the ignition device to disable ignition.
When the first moment is located outside the preset time period before the second moment, the gas concentration can be reduced to be within the safety range at the second moment, and at the moment, if the ignition equipment is ignited, no potential safety hazard exists, so that at the moment, if the ignition event is acquired, an alarm signal can be not generated.
In still other examples, if the first time is after the second time, it indicates that the gas is leaking after ignition, and the potential safety hazard is relatively small, then the alarm signal may not be generated. Thus, it may be determined that the alarm signal is not generated when the first time is located outside of a preset period of time before the second time, or when the second time is located before the first time. Therefore, false alarm of the gas alarm can be reduced.
In some examples, the ignition device sends multiple ignition events, each corresponding to a second time, where the second time is multiple.
When the number of the first time is one and the number of the second time is multiple, on the basis of a gas alarm method shown in fig. 1, the embodiment of the present invention further provides a possible implementation manner, as shown in fig. 3, which is a flowchart of a third implementation manner of a gas alarm method in the embodiment of the present invention, where the method may include:
S310, acquiring a first moment of alarm request information generated by a gas alarm based on a gas concentration signal and a second moment of an ignition event generated by an ignition device, wherein the ignition device is used for igniting combustible gas for life through ignition, and the ignition event is generated by the ignition device during ignition;
s320, when at least one second moment is positioned before the first moment and the difference value between the latest second moment in the plurality of second moments and the first moment is smaller than or equal to a first preset time difference threshold value, determining that no alarm signal is generated;
s330, determining to generate an alarm signal when at least one second moment is positioned before the first moment and the difference between the latest second moment and the first moment is larger than a first preset time difference threshold;
and S340, when the generation of the alarm signal is determined, the gas alarm is instructed to generate the alarm signal.
In some examples, when at least one second time is located before the first time, it may be stated that the ignition device is firing before the gas diffuses to the gas alarm, where the gas is typically insufficient for the ignition device to burn or the ignition device is firing unsuccessfully resulting in a portion of the gas diffusing. However, there is also a possibility of gas diffusion caused by gas pipe leakage, and therefore, in order to exclude a case where the gas alarm caused by gas pipe leakage generates alarm request information, a first preset time difference threshold may be set here, and when a difference between a latest second time of the plurality of second times and the first time is less than or equal to the first preset time difference threshold, it may be indicated that the gas diffusion is caused by unsuccessful ignition of the ignition device. It may be determined that no alert signal is generated.
If the difference between the latest second moment and the first moment is larger than a first preset time difference threshold value, the gas diffusion is not caused by unsuccessful ignition or insufficient combustion of the ignition equipment, and at the moment, the generation of an alarm signal can be determined; and further instructs the gas alarm to generate an alarm signal.
By the embodiment of the invention, false alarm of the gas alarm can be reduced on the premise of ensuring safety.
In some examples, when the first time is a plurality of times and the second time is a plurality of times, on the basis of a gas alarm method shown in fig. 1, the embodiment of the present invention further provides a possible implementation manner, as shown in fig. 4, which is a flowchart of a fourth implementation manner of a gas alarm method in the embodiment of the present invention, where the method may include:
s410, acquiring a first moment of alarm request information generated by a gas alarm based on a gas concentration signal and a second moment of an ignition event generated by an ignition device, wherein the ignition device is used for igniting combustible gas for life through ignition, and the ignition event is generated by the ignition device during ignition;
s420, determining to generate an alarm signal when at least one first moment is positioned before a second moment, and indicating the ignition equipment to prohibit ignition;
S430, determining that no alarm signal is generated when the plurality of first moments are all located after the second moment and the difference value between the latest first moment and the second moment in the plurality of first moments is smaller than or equal to a second preset time difference threshold value;
s440, determining to generate an alarm signal when the plurality of first moments are all located after the second moment and the difference value between the latest first moment and the second moment in the plurality of first moments is larger than a second preset time difference threshold;
s450, when the generation of the alarm signal is determined, the gas alarm is instructed to generate the alarm signal.
In some examples, when at least one first time is located before a second time, it may be stated that since the gas alarm and the ignition device are located at different positions, it may be stated that when the ignition device ignites, gas has spread from the gas outlet of the ignition device to the installation position of the gas alarm, at which time, if the ignition device ignites successfully, there may be a safety hazard, and therefore, in order to prevent a safety problem, it may be determined to generate an alarm signal and instruct the ignition device to prohibit ignition. In this way, open fires can be avoided, thereby avoiding safety problems.
In some examples, when the first time of the alarm request information generated based on the gas concentration signal is located after the second time and the alarm request information generated based on the gas concentration signal is located a plurality of times, it may be caused by that the ignition device burns insufficiently or that the ignition device ignites unsuccessfully to cause a part of the gas to diffuse. And possibly also due to gas piping leaks.
Therefore, in order to exclude the case of the alarm request information generated based on the gas concentration signal due to the gas pipe leakage, the second preset time difference threshold may be set, and when the plurality of first moments are all located after the second moment and the difference between the latest first moment and the second moment in the plurality of first moments is less than or equal to the second preset time difference threshold, it may be indicated that the gas diffusion is caused by unsuccessful ignition of the ignition device or insufficient combustion of the ignition device, and it may be determined that the alarm signal is not generated at this time.
If the first moments are all located after the second moment and the difference value between the latest first moment and the second moment in the first moments is larger than a second preset time difference threshold value, the gas diffusion is caused by the fact that the ignition equipment is not successfully ignited or insufficiently combusted, and the gas pipeline is leaked, so that the generation of an alarm signal can be determined. And further instructs the gas alarm to generate an alarm signal.
Therefore, false alarm of the gas alarm can be reduced on the premise of ensuring safety.
On the basis of a gas alarm method shown in fig. 1, the embodiment of the invention also provides a possible implementation manner, as shown in fig. 5, which is a flowchart of a fifth implementation manner of the gas alarm method in the embodiment of the invention, and the method may include:
S510, acquiring a first moment of alarm request information generated by a gas alarm based on a gas concentration signal and a second moment of an ignition event generated by an ignition device, wherein the ignition device is used for igniting combustible gas for life through ignition, and the ignition event is generated by the ignition device during ignition;
s520, when the detection signal of the human body detected by the human body detection equipment is obtained and the first moment is positioned in a preset time period before the second moment, determining to generate an alarm signal;
s530, when the detection signal of the human body detected by the human body detection equipment is obtained and the first moment is located in a preset time period after the second moment, determining that an alarm signal is not generated;
s540, when the generation of the alarm signal is determined, the gas alarm is instructed to generate the alarm signal.
In some examples, there may also be human activity in a scene using gas alarms and ignition devices, e.g., a person moving in the scene or a person stationary in the scene. In order to avoid false alarms of gas alarms and to protect the personal safety of people when they are in the scene. In the embodiment of the invention, the gas alarm and the ignition device can be also in communication connection with the human body detection device, so that the device applying the gas alarm method of the embodiment of the invention can acquire the detection signal when the human body detection device detects the human body. The human body detection device may be an image detection device or an infrared detection device, which may be all that is required.
When the device applying the gas alarm method of the embodiment of the invention acquires the detection signal, it can be explained that a person exists in the scene, at this time, it can be judged whether the first moment is located in a preset time period before the second moment, if so, in order to avoid potential safety hazards caused by the fact that the gas concentration in the scene is still higher at the second moment, an alarm signal can be generated, and the ignition device can be instructed to prohibit ignition.
If the first time is judged to be positioned before the second time and is not in the preset time period before the second time, the gas concentration is reduced to be within the safety range, and at the moment, it can be determined that the alarm signal is not generated.
When the device applying the gas alarm method of the embodiment of the invention acquires the detection signal, the first moment is located in the preset time period after the second moment, which can indicate that the gas diffused in the scene is caused by unsuccessful ignition or insufficient gas combustion after the first moment, and at the moment, it can be determined that the alarm signal is not generated. If the first time is located outside the preset time period after the second time, it can be stated that the gas diffused in the scene is not caused by unsuccessful ignition or insufficient combustion of the gas, and it can be determined that an alarm signal is generated.
Therefore, when a human body is detected, false alarm of the gas alarm can be reduced on the premise of ensuring the safety of the human body.
In some examples, when the gas alarm generates an alarm signal, there may or may not be any person in the scene where the gas alarm is deployed, and in order to remind people in time, on the basis of any one of the embodiments shown in fig. 1 to 5, an implementation manner for indicating the gas alarm to generate an alarm signal is further provided, for example:
when a detection signal of a human body detected by the human body detection equipment is obtained, the gas alarm is instructed to generate voice alarm information so that the gas alarm carries out voice alarm;
and when the detection signal of the human body detection device is not acquired, the gas alarm is instructed to generate a remote alarm signal, so that the gas alarm sends the remote alarm signal to the remote device.
When the detection signal of the human body detected by the human body detection equipment is obtained, the existence of a person in a scene monitored by the human body detection equipment can be indicated, at the moment, the gas alarm can be indicated to generate voice alarm information, and then the gas alarm can broadcast the voice alarm information to carry out voice alarm, so that the person in the monitored scene can be reminded.
When the detection signal of the human body detection equipment is not obtained, the fact that no person exists in the scene monitored by the human body detection equipment is indicated, and at the moment, in order to remind people in time, the gas alarm can be indicated to generate a remote alarm signal.
In some examples, the gas alarm may store identification information of the remote device, where the identification information may be an IP address, a MAC address, a mailbox, a phone number, and the like of the remote device. The remote device may be a smart phone or a personal computer with communication capabilities. When the gas alarm acquires information indicating the generation of the remote alarm signal, the gas alarm can generate the remote alarm signal, and then the generated remote alarm signal is sent to the remote equipment based on the identification information of the remote equipment.
The remote alarm signal can be text information, voice information, video information or the combination information of at least two of the three information. The video information may comprise image frames of the ignition device.
