Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings 1 to 6 and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The embodiment of the application discloses a fire monitoring and early warning method.
Referring to fig. 1, a fire monitoring and early warning method includes:
step S101, monitoring the current data concentration of each fire data factor in a building;
the current data concentration of the fire data factors in multiple dimensions is monitored, so that the fire signs can be comprehensively and accurately perceived;
step S102, obtaining preset concentration threshold values of all fire data factors;
the fire data factors of each dimension can preset a concentration threshold according to actual conditions, and when the concentration threshold is exceeded, the potential fire risk or hazard can be indicated;
step S103, judging whether the current data concentration of each fire data factor exceeds a corresponding preset concentration threshold value or not; if not, jumping to step S104; if yes, jump to step S105;
step S104, determining the current concentration ratio of the fire data factors according to the current data concentration of the fire data factors and the corresponding preset concentration threshold;
the ratio of the current concentration of the fire data factor, namely the ratio of the current data concentration to the corresponding preset concentration threshold value, can reflect the risk degree of the current data concentration of the fire data factor, and as the current data concentration is smaller than the preset concentration threshold value, the corresponding current concentration ratio is between 0 and 1, when the ratio is closer to 1, the current data concentration is closer to the preset concentration threshold value, and the risk degree is higher; when the ratio is far from 1, the difference value between the current data concentration and the preset concentration threshold value is larger, and the risk degree is lower;
it can be understood that when the current concentration ratio is larger, the risk degree is higher, and the corresponding monitoring frequency also needs to be correspondingly increased so as to reduce the occurrence of the condition that the data concentration information is not obtained timely; otherwise, correspondingly reducing the amount of the resource waste;
step S1041, determining a corresponding preset monitoring frequency according to the current concentration ratio of the fire data factor, and adjusting the current monitoring frequency of the fire data factor to the preset monitoring frequency;
step S105, determining a corresponding early warning type according to the fire data factor and carrying out corresponding early warning; the early warning type comprises fire early warning and harmful substance early warning.
In the above embodiment, in the process of fire monitoring, the current data concentrations of the fire data factors in multiple dimensions can be monitored and compared with the corresponding preset concentration thresholds respectively, whether the current data concentrations of the fire data factors in each dimension exceed the corresponding preset concentration thresholds is judged, if not, the current concentration ratio of the current data concentrations to the preset concentration thresholds is calculated, so as to determine the risk degree of the current data concentrations and then adaptively adjust the monitoring frequency of the fire data factors, thereby reducing the occurrence of the condition that the fire risk early warning is not timely due to the fact that part of fire data factors are not monitored timely; if the fire disaster data factor exceeds the preset fire disaster data factor, the corresponding early warning type is determined and corresponding early warning is carried out, so that preventive measures can be conveniently and timely taken, the occurrence and the spread of the fire disaster are reduced, and the safety is improved.
In one embodiment of the application, the fire data factor includes chemical warfare agent concentration, toxic harmful gas concentration, combustible gas concentration, biological harmful factor concentration, and fire smoke concentration.
Wherein, the chemical warfare agent concentration can adopt chemical warfare agent sensors, such as chemical warfare agent detectors or gas chromatographs, etc.; the concentration of the toxic and harmful gas can be measured by a harmful gas sensor, a harmful gas detector, a gas chromatograph, etc.; the concentration of the combustible gas can be a combustible gas sensor, such as a combustible gas detector or a gas concentration sensor; the concentration of the biological harmful factors can adopt a biosensor or a biological detection technology, such as a biosensor array or a PCR technology, etc.; the fire smoke concentration may be measured using a smoke sensor, such as an optical smoke sensor or an ionization smoke sensor.
It can be understood that by monitoring the concentration of chemical warfare agents, the concentration of toxic and harmful gases and the concentration of biological harmful factors, it is possible to determine whether harmful substances are present in the environment, thereby evaluating the risk of fire on human health; by monitoring the combustible gas concentration and the fire smoke concentration, the combustion state of the fire can be judged, thereby helping to determine the fire extinguishing strategy.
In the embodiment, the fire data factors are monitored in a multi-sensor combination mode, and the fire data factors with different dimensions are used for mutual verification, so that more accurate and comprehensive fire information can be provided, and the accuracy of fire risk early warning is improved.
Referring to fig. 2, as an embodiment of determining the corresponding preset monitoring frequency according to the current concentration ratio of the fire data factor in step S1041, the specific steps include:
step S201, determining a corresponding monitoring frequency comparison table according to fire data factors;
the monitoring frequency comparison table is preconfigured with a corresponding relation between a plurality of groups of ratio intervals and preset monitoring frequencies.
Step S202, determining a corresponding ratio interval according to the current concentration ratio of the fire data factors based on a monitoring frequency comparison table;
step S203, corresponding preset monitoring frequency is determined according to the ratio interval.
It should be noted that, the preset monitoring frequency is an optimal monitoring frequency when the current concentration ratio is in the ratio section, the optimal monitoring frequency can be set according to actual conditions, and the length of each ratio section, the opening and closing of the end points and the number of the ratio sections can be configured according to actual conditions.
In the above embodiment, a monitoring frequency comparison table corresponding to each fire data factor is pre-configured, after determining the current concentration ratio of each fire data factor, a corresponding ratio interval and a preset monitoring frequency corresponding to the ratio interval are determined according to the current concentration ratio, and then the current monitoring frequency is adaptively adjusted according to the preset monitoring frequency, so that the risk degree of each fire data factor can be accurately estimated and matched with a corresponding monitoring strategy, and the monitoring requirements of fire data factors with different risk degrees can be met; meanwhile, if the current concentration ratio is changed in a certain ratio interval, the corresponding monitoring frequency does not need to be changed by setting a plurality of ratio intervals, so that the condition that the monitoring frequency is frequently adjusted is reduced.
In addition, the monitoring frequency comparison table corresponding to the fire data factor of each dimension may be configured according to the monitoring standard or the actual monitoring requirement of each fire data factor, or may be configured as the same monitoring frequency comparison table, which is not limited in the embodiment of the present application.
In one embodiment of the present application, each ratio interval in the monitoring frequency comparison table has no intersection, and each ratio interval corresponds to a preset monitoring frequency; it can be understood that, because the current data concentration is smaller than the preset concentration threshold, the corresponding current concentration ratio is between 0 and 1, if the current concentration ratio is closer to 1, the current data concentration is closer to the preset concentration threshold, the corresponding risk degree is higher, and therefore, the ratio interval in which the current concentration ratio is located can be configured with a relatively higher preset monitoring frequency, so that timeliness of data information acquisition is ensured; if the current concentration ratio is far from 1, the difference value between the current data concentration and the preset concentration threshold value is larger, and the corresponding risk degree is lower, so that a relatively lower preset monitoring frequency can be configured in a ratio interval where the current concentration ratio is located, and the waste of system resources is reduced.
As an implementation manner of determining the corresponding early warning type according to the fire data factor and performing the corresponding early warning in step S105, the specific steps include:
judging according to the fire data factor;
if the fire data factor with the current data concentration exceeding the preset concentration threshold is the chemical warfare agent concentration, the toxic and harmful gas concentration or the biological and harmful factor concentration, determining the corresponding early warning type as harmful substance early warning, generating corresponding harmful substance early warning information according to the position information of the building and sending the information to a maintenance terminal;
if the fire data factor with the current data concentration exceeding the preset concentration threshold is the combustible gas concentration or the fire smoke concentration, the corresponding early warning type is fire early warning, and corresponding fire early warning information is generated according to the position information of the building and is sent to the maintenance terminal.
It should be noted that, when any one of three fire data factors including chemical warfare agent concentration, toxic and harmful gas concentration or biological harmful factor concentration exceeds a corresponding preset concentration threshold, the harmful substance early warning can be triggered; when any one of the combustible gas concentration or the fire smoke concentration exceeds a corresponding preset concentration threshold value, fire early warning can be triggered.
In one embodiment of the application, when the early warning type is harmful substance early warning, maintenance personnel can be reminded of timely isolating pollution sources or carrying out ventilation treatment and the like through the harmful substance early warning information, in addition, when the leakage risk of the harmful substance exists, the maintenance personnel can be reminded of reporting the leakage condition of the harmful substance to related departments so as to seek professional emergency support;
in another embodiment of the application, when the early warning type is fire early warning, the fire early warning information can remind maintenance personnel to start a smoke discharging system, a spraying system or check a combustible gas source and cut off the combustible gas source in time, and meanwhile, if the fire has occurred or the fire starts to spread, the maintenance personnel can be reminded to use fire fighting facilities such as a fire extinguisher to perform initial extinguishing in time, so that the possibility of fire spreading is reduced.
It is understood that the maintenance terminal may be an intelligent mobile terminal of a field maintenance person, such as a mobile phone, a tablet computer, etc.
In the above embodiment, when the chemical warfare agent concentration, the toxic and harmful gas concentration or the biological harmful factor concentration exceeds the preset concentration threshold, the situations such as harmful gas leakage, chemical accidents or biological hazards may exist, so that the early warning type can be correspondingly determined to be harmful substance early warning, and maintenance personnel can be reminded to timely take emergency measures such as isolating pollution sources or performing ventilation treatment through the harmful substance early warning information; when the concentration of the combustible gas or the concentration of the fire smoke exceeds a preset concentration threshold, fire risk hidden danger or fire disaster situations can exist, so that the type of the early warning can be correspondingly determined to be fire early warning, and maintenance personnel can be reminded of starting a smoke discharging system or checking the gas source of the combustible gas through fire early warning information to cut off in time.
Referring to fig. 3, as a further embodiment of the fire monitoring and early warning method, after the step of determining the corresponding early warning type according to the fire data factor and performing the corresponding early warning in step S105, the method further includes;
step S106, acquiring a data concentration change value of the fire data factor after a preset duration;
the preset duration is a preset time interval length, for example, may be set to 5 minutes or 10 minutes, which is not limited in the embodiment of the present application; in addition, the data concentration change value is the difference value between the current data concentration and the data concentration after the preset time length;
step S107, judging whether the data concentration change value of the fire data factor is smaller than a preset concentration change threshold value or not; if yes, jump to step S108; if not, not executing any operation;
wherein, the preset concentration change threshold can be manually set and adjusted according to historical experience and actual demand, and the embodiment of the application does not limit the method;
it can be understood that after the early warning, maintenance personnel can take corresponding treatment measures, the data concentration should be gradually reduced, the obtained data concentration change value should be a non-negative value, and if the obtained data concentration change value is smaller than a preset concentration change threshold value, the abnormal concentration change can be indicated; in addition, even if the data concentration is raised in a special case so that the data concentration variation value is a negative value, at this time, the data concentration variation value is still smaller than the preset concentration variation threshold value, it can be still indicated that there is a concentration variation abnormality.
And step S108, sending a concentration abnormality signal of the fire data factor to the management terminal according to the position information of the building.
The management terminal can be an intelligent mobile terminal of a manager, such as a mobile phone, a tablet personal computer and the like, and also can be a computer terminal in a monitoring room.
In the above embodiment, after the early warning, if the data concentration variation value of the fire data factor is still smaller than the preset concentration variation threshold, it may be that the maintainer does not take emergency measures in time or the emergency measure effect is poor, and the concentration anomaly information is sent to remind the manager to check, so that the potential problem is found as soon as possible and measures are taken for processing, and if necessary, a fire alarm call can be dialed or related departments can be notified to report the fire situation, so as to dispatch the fire fighting team in time for fire suppression.
Referring to fig. 4, as a further embodiment of the fire monitoring and early warning method, the fire monitoring and early warning method further includes:
step S301, judging whether the current data concentration of each fire data factor does not exceed a corresponding preset concentration threshold value; if yes, jump to step S302; if not, jumping to step S105;
step S302, determining the current concentration ratio of each fire data factor according to the current data concentration of each fire data factor and the corresponding preset concentration threshold value;
the ratio of the current concentration of the fire data factor, namely the ratio of the current data concentration to the corresponding preset concentration threshold value, can reflect the risk degree of the current data concentration of the fire data factor, and as the current data concentration is smaller than the preset concentration threshold value, the corresponding current concentration ratio is between 0 and 1, when the ratio is closer to 1, the current data concentration is closer to the preset concentration threshold value, and the risk degree is higher; when the ratio is far from 1, the difference value between the current data concentration and the preset concentration threshold value is larger, and the risk degree is lower; it will be appreciated that the greater the current concentration ratio, the higher the risk level is relatively;
step S303, carrying out weighted average according to the current concentration ratio of each fire data factor and preset weight, and calculating to obtain a fire risk index;
in one embodiment of the present application, the fire risk index = (chemical warfare agent preset weight x chemical warfare agent current concentration ratio) + (toxic harmful gas preset weight x toxic harmful gas current concentration ratio) + (combustible gas preset weight x combustible gas current concentration ratio) + (biological harmful factor preset weight x biological harmful factor current concentration ratio) + (fire smoke preset weight x current concentration ratio of fire smoke concentration);
it should be noted that, the preset weight of each fire data factor may be preset according to the importance degree and the contribution degree to the fire risk of the fire data factor, and the sum of the preset weights of each fire data factor is equal to 1.
Because different application scenes and requirements may have different importance on each fire data factor, when the weight configuration is performed, the fire data factors with higher occurrence frequency of fire risks in past fire events of the building can be analyzed for configuration, and the configuration can also be performed according to actual conditions in the building and actual requirements of monitoring maintenance personnel, for example, when the release of toxic and harmful gases is considered to possibly cause greater threat to personnel health and safety, the corresponding toxic and harmful gas concentration can be set with higher preset weight; when the fire smoke concentration is considered to more easily reflect the occurrence or even the spread of a fire, the corresponding fire smoke concentration may be set with a higher preset weight.
Step S304, judging whether the fire risk index is larger than a preset fire risk index threshold value or not according to the fire risk index, if yes, jumping to step S305; if not, not executing any operation;
it will be appreciated that the fire risk index is used to evaluate the extent of fire risk, the greater the fire risk index, the greater the risk of fire present; in addition, the preset fire risk threshold can be manually set and adjusted according to historical experience, and the embodiment of the application is not limited to the setting;
step S305, a fire risk prompting signal is generated according to the position information of the building and is sent to the maintenance terminal.
Wherein, fire risk prompt signal is used for prompting that maintainer probably has potential fire risk.
In the above embodiment, since the fire risk is not only dependent on the concentration of a single fire data factor, but also related to the interaction and accumulation effect between each fire data factor, although monitoring results in that each fire data factor is not out of standard, it is still necessary to accurately and comprehensively evaluate the fire risk by integrating a plurality of fire data factors and judge whether the fire risk exceeds the preset fire risk index threshold according to the fire risk index, if so, it indicates that there is a potential fire risk, and a risk prompt is performed on maintainers through a fire risk prompt signal, so that a series of risk preventive measures are conveniently taken in advance to reduce the fire risk and ensure the safety of personnel and property.
