Therefore, the embodiment provides a gas safety supervision method based on the internet of things cloud platform.
The method for monitoring and managing gas safety based on the internet of things cloud platform provided by the application can refer to fig. 1, and fig. 1 is a schematic flow diagram of the method for monitoring and managing gas safety based on the internet of things cloud platform, which is provided by the embodiment of the application, and is applied to the internet of things cloud platform. The method includes steps S101 to S104.
S101, acquiring the current gas concentration, wherein the current gas concentration is the gas concentration detected by the target alarm.
In the above steps, the internet of things cloud platform obtains the current gas concentration through the gas alarms arranged in the monitoring area in advance, the gas concentration value can reflect the gas concentration in the area, for convenience of expression, the embodiment uses one gas alarm to explain (i.e. the target alarm), in actual cases, the internet of things cloud platform can monitor the gas concentration of a plurality of areas through a plurality of gas alarms at the same time; in addition, in the actual situation, the gas concentration acquired by the gas alarm may not be consistent with the gas concentration at the edge of the monitoring area, so that for simplifying the scheme description, the gas concentration measured by the gas alarm is still defaulted to be the gas concentration at each part of the monitoring area; in practical application, a user can add an additional value to the measured value of the gas alarm according to the requirement so as to simulate the condition that the gas concentration in the monitored area is greater than the concentration measured by the gas alarm.
In one possible embodiment, the obtaining the current gas concentration specifically includes any one of the following modes: acquiring the current gas concentration every preset time period; and responding to the inquiring operation of the user on the gas concentration, and acquiring the current gas concentration.
Specifically, the cloud platform of the internet of things can acquire the current gas concentration in any one of two modes; the gas concentration is obtained by the internet of things cloud platform at each preset time interval, the length of the preset time interval can be set according to the requirements of staff, and in general, when the preset time interval is set to be shorter, the internet of things cloud platform can obtain the gas concentration more frequently, so that abnormal conditions possibly existing in the gas can be found more timely; the other mode is that the cloud platform of the Internet of things responds to the gas concentration query operation of the user, obtains the current gas concentration and displays the current gas concentration to the user; according to the user setting, the gas concentration values of a plurality of areas can be obtained at the same time through one query operation, so that multi-area monitoring can be performed at the same time.
S102, judging whether the current gas concentration is larger than a normal threshold value and smaller than a dangerous threshold value.
In the above steps, the internet of things cloud platform judges whether the current gas concentration value is greater than a normal threshold value and less than a dangerous threshold value, wherein the normal threshold value is usually set as a concentration value at which gas is likely to cause harm to people, such as methane, when the concentration in the air reaches ten percent, people can be choked and die, when the content is five percent and fifteen percent, the fire source can be exploded, and the normal threshold value is set to be five percent at the moment; while the risk threshold is typically set to a concentration value that has a high probability of being life threatening, still taking methane as an example, the risk threshold is set to ten percent rather than fifteen percent; the specific threshold setting is adjusted according to the type of the monitored fuel gas, for example, the carbon monoxide concentration in the air is not more than 0.0024%, and the threshold setting can be performed according to the data.
In one possible embodiment, after determining whether the current gas concentration is greater than the normal threshold and less than the hazard threshold, the method further comprises: and if the current gas concentration is greater than or equal to the dangerous threshold, sending emergency evacuation information to a preset loudspeaker to inform a user of evacuation, wherein the emergency evacuation information comprises prompt information for avoiding using electric appliances and a switch.
Specifically, when the current gas concentration is greater than or equal to a dangerous threshold, the fact that the gas in the monitoring area is leaked to the extent that life is dangerous is indicated, at the moment, the cloud platform of the internet of things sends emergency evacuation information to equipment for conveying information such as a loudspeaker and the like which are arranged in advance, and in addition, the gas leakage information is also sent to a gas safety supervision department and a terminal reserved by a user in advance, and the user and a manager are timely prompted to conduct treatment and assistance; meanwhile, the emergency evacuation information also comprises attention points during evacuation, for example, when the methane concentration is in the range of 5% -15%, the fire source is exploded, and at the moment, the prompting information of an electric appliance or a switch which cannot use the switch and the like to manufacture a heat source such as sparks is added.
In one possible embodiment, after the emergency evacuation information is sent to the preset speaker, the method further includes: displaying prompt information of whether an emergency rescue call needs to be dialed or not to a user; responding to the operation of the user allowing to dial the emergency rescue telephone, and dialing the reserved emergency rescue telephone; after the call is confirmed, a request rescue voice is generated and played, wherein the request rescue voice comprises the position information of the target alarm.
Specifically, after the cloud platform of the internet of things sends the emergency evacuation information to the preset speaker, in order to ensure that the emergency evacuation information can be timely based on the assistance of the user, prompt information of whether the user needs to dial an emergency rescue phone is displayed to the user, wherein the prompt information can be played through the speaker or displayed through the mobile terminal of the user, and the method is not limited; after obtaining permission from a user to dial an emergency rescue phone, the internet of things cloud platform automatically dials over the emergency rescue phone reserved in advance, for example, 119, the number of a neighbor reserved in advance, or the like; after the call is confirmed, a voice for requesting rescue is generated and played for help seeking, and preferably, the voice for requesting rescue can comprise the position information of the target alarm, the area where the gas leakage exists, the population information of the user and the like, so that a rescuer can provide better rescue according to the information; the method simplifies the steps of the operation required by the user for help, and can also timely inform the rescue personnel to rescue when the physical state of the user is poor (such as the gas poisoning sign is already present or the old who is inconvenient to move alone at home, etc.).
And S103, if the current gas concentration is larger than the normal threshold and smaller than the dangerous threshold, acquiring gas leakage processing time according to the current gas concentration and the dangerous threshold.
In the above steps, when the cloud platform of the internet of things judges that the current gas concentration is greater than the normal threshold and less than the dangerous threshold, the gas concentration is not quite dangerous at the moment, and the preferable evacuation time is also provided; and the cloud platform of the Internet of things calculates and predicts the gas leakage processing time according to the current gas concentration and the dangerous threshold value.
In one possible implementation manner, the gas leakage processing time is obtained according to the current gas concentration and the dangerous threshold value, and specifically includes: acquiring the rising speed of the concentration of the fuel gas; inputting the rising speed of the gas concentration and the current gas concentration into a preset regression model to obtain a relation curve of the gas concentration and time; acquiring the arrival time of the dangerous threshold corresponding to the dangerous threshold according to the relation curve; and acquiring the gas leakage processing time according to the dangerous threshold value arrival time.
Specifically, the cloud platform of the internet of things acquires the gas concentration rising speed through a gas alarm, wherein the specific acquisition mode is that a time period (such as a time period with the time length of 0.1 second) with a short time interval including the current moment is selected, the gas concentration at two endpoint moments of the time period is acquired, the concentration difference is obtained by calculating a difference value, and then the gas concentration rising speed at the current moment can be approximately obtained by dividing the concentration difference by the length of the time period; in order to ensure that the gas leakage treatment time is more accurately predicted, the gas concentration rising speeds at different moments can be obtained, the data and the current gas concentration are input into a preset regression model trained in advance, a predicted gas concentration and time relation curve is obtained, and each time point corresponds to a gas concentration value in the relation curve; and searching the gas concentration value with the dangerous threshold value for the first time on the curve, acquiring the dangerous threshold value arrival time corresponding to the gas concentration value, and subtracting the current moment from the dangerous threshold value arrival time to obtain the gas leakage processing time.
S104, sending an alarm prompt to a user, wherein the alarm prompt comprises the gas leakage processing time and the position information of the target alarm.
