Detailed Description
The terms "first," "second," "third," "fourth" and the like in the description and in the claims and in the above drawings, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments described herein may be implemented in other sequences than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. The following description of the embodiments of the present application 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 application, but not all embodiments.
In order to solve the problem of poor fire source positioning capability when using a smoke sensor in a large-area and large-space scene, refer to fig. 1, which is a schematic flow chart of a safety monitoring method based on a distributed smoke alarm provided by an embodiment of the application, the method specifically may include: steps S110, S120, S130, and S140.
S110, acquiring induction signals of a plurality of distributed smoke alarms in a target space area, wherein the distributed smoke alarms are located in a communicated space area;
for example, the plurality of distributed smoke alarms may be located in the same open station space or a relatively open exhibition hall, which is not limited herein.
Illustratively, the above-mentioned communicated space region means that air or smoke can freely circulate at the space station.
S120, under the condition that smoke induction signals of a plurality of distributed smoke alarms are received, acquiring generation time of each smoke induction signal and first identification information of a smoke alarm to which each smoke induction signal belongs;
illustratively, the smoke alarm generates a smoke-sensing signal back in the event that smoke or smoke reaching a certain concentration is detected. The first identification information may be used to distinguish between smoke alarms.
S130, inquiring the position relation information of the smoke alarm to which each smoke induction signal belongs in design data based on the acquired identification information;
for example, the first identification information itself may also be made to carry position information, so as to obtain position relationship information of the smoke alarm to which each smoke sensing signal belongs.
And S140, predicting the position information of the fire source according to the position relation information and the generation time of each smoke induction signal.
For example, under the condition that the influence of external air flow is not considered in the indoor environment, the generation time of the smoke sensing signal, namely the time when the smoke alarm detects that smoke or the smoke reaches a certain concentration, can indirectly reflect the position proportion relation of the fire source relative to the surrounding smoke alarm. The positional relationship of the fire source location to these smoke alarms that detect smoke can be determined to some extent.
In summary, according to the safety monitoring method based on the distributed smoke alarms provided by the embodiment of the application, sensing signals of a plurality of distributed smoke alarms in a target space area are obtained, wherein the distributed smoke alarms are located in a communicated space area; under the condition that smoke induction signals of a plurality of distributed smoke alarms are received, acquiring generation time of each smoke induction signal and first identification information of a smoke alarm to which each smoke induction signal belongs; inquiring the position relation information of the smoke alarm to which each smoke induction signal belongs in design data based on the obtained identification information; and predicting the position information of the fire source according to the position relation information and the generation time of each smoke induction signal. Therefore, the position relation between each smoke alarm generating the smoke sensing signal and the fire source can be easily estimated by using the known distributed design data of the distributed smoke alarms and the time when smoke reaches the surrounding smoke alarms, so that the specific position of the fire source can be estimated. The problem that the capability of locating the specific position of a fire source is poor in a scene with the characteristics of large area, wide space and the like is avoided, and the situation that smoke is detected in the same space area to exceed a certain degree and then the fire is sprayed and extinguished in the space area without difference is avoided. Unnecessary resource waste and damage to property such as electronic equipment in a relatively safe area after indiscriminate spraying are avoided.
According to some embodiments, further comprising:
determining second position information of target spraying units around the fire source based on the fire source position information;
and calculating the spraying pressure of the target spraying unit according to the second position information and the fire source position information, wherein the spraying pressure is positively correlated with the spraying distance.
By way of example, the main spray area reached by the spray liquid can be deduced by adjusting the spray pressure and combining the principle of only falling bodies, which spray units can be opened according to the fire source position information, and the spray pressure of the spray units can be adjusted according to the distance between each spray unit and the predicted fire source position, so that the main spray area of each spray unit is located near the fire source position as much as possible.
According to some embodiments, each spray unit has a plurality of independent spray ports circumferentially distributed, the spray pressure is inversely related to the number of on-state spray ports of each spray unit, and the spray pressure is inversely related to the number of off-state spray ports of each spray unit, the method further comprising:
and determining the number and the position of the spray ports to be conducted by the target spray unit based on the second position information of the target spray unit and the fire source position information.
By way of example, the spraying distance can be further adjusted by the number of the spraying ports of the spraying units, and the spraying distance of the spraying units can be adjusted more flexibly by not only relying on the valves of the spraying units and even the main valves to which the plurality of spraying units belong, and the effective spraying range of the spraying units in one direction or in certain directions is further improved. The spraying liquid of more spraying units is convenient to concentrate at the positions of the fire sources which are far away.
According to some embodiments, any position of the target space region is within a maximum spray range of at least two surrounding spray units, and the determining the number of spray ports and the prescribed positions of the target spray unit to be conducted based on the second position information of the target spray unit and the fire source position information includes:
and determining the number of spray ports to be conducted and the prescribed position of each target spray unit based on the second position information of each target spray unit and the fire source position information, so that the main spray water flows of at least two target spray units overlap at the fire source position.
By way of example, in case that the predicted fire source position is between the spraying units a and b and is closer to b, the position of the main spraying water flow can be controlled by adjusting the pressure of the liquid sprayed from the spraying units by adjusting the valves of the spraying units, and then the positions of the main spraying water flows of the spraying units a and b overlap at the fire source position, so that the fire extinguishing operation can be performed more effectively on the fire source position. After the number of the circumferential spraying ports and the prescribed positions of the spraying units a and b are controlled, the positions of the main spraying water flows of the spraying units a and b can be further overlapped at the positions of the fire sources, for example, the spraying ports on the side of the spraying unit a facing the spraying unit b are opened to close other ports, the spraying ports on the side of the spraying unit b facing the spraying unit a are opened to close other ports, and the positions of the main spraying water flows at the moment of a and b can be adjusted by adjusting the number of the ports on which a and b are opened, so that the main spraying water flows of the two target spraying units are overlapped at the positions of the fire sources. On the one hand, the water pressure and the spraying distance can be adjusted without the help of a valve, and on the other hand, the spraying distance can be adjusted by combining the valve and the spraying port, so that the effective range of the spraying distance is wider. Even the spraying units d and e which are far away from the fire source position can participate in the fire extinguishing operation of the fire source position.
According to some embodiments, further comprising:
predicting a fire spreading trend according to the position relation information and the generation time of each smoke induction signal, wherein the spreading trend comprises a spreading direction;
and generating a smoke pre-sensing signal in a target smoke alarm which does not generate a smoke sensing signal in advance based on the spreading direction and the design data or starting a target spraying unit around the target smoke alarm in advance.
For example, in the case where smoke alarms a, b, c arranged in the same first direction generate smoke pre-sensing signals at a time, it is possible to judge that the fire is spreading in the above first direction. Then a smoke pre-sense signal may be generated in a smoke alarm d that is temporarily not generating a smoke sense signal in the first direction or a target spray unit surrounding the smoke alarm d may be turned on in advance.
According to some embodiments, further comprising:
predicting a fire spreading trend according to the position relation information and the generation time of each smoke induction signal, wherein the spreading trend comprises a spreading path;
and generating a smoke pre-sensing signal in a target smoke alarm which does not generate a smoke sensing signal in advance based on the spreading path and the design data or starting a target spraying unit around the target smoke alarm in advance.
According to some embodiments, in the case where the epidemic trend includes an epidemic direction, the target smoke alarm is a smoke alarm that is adjacent to the smoke alarm to which the smoke sensing signal belongs in the epidemic direction that is temporarily not generating a smoke sensing signal:
in the case where the propagation trend includes a propagation path, the target smoke alarm is a smoke alarm that temporarily does not generate a smoke sensing signal along the propagation path.
Referring to fig. 2, an embodiment of a security monitoring device based on a distributed smoke alarm according to an embodiment of the present application may include:
a first acquisition unit 21, configured to acquire sensing signals of a plurality of distributed smoke alarms in a target spatial area, where the plurality of distributed smoke alarms are in a communicated spatial area;

and a prediction unit 24, configured to predict the fire source position information according to the position relationship information and the generation time of each smoke sensing signal.
In summary, the safety monitoring device based on the distributed smoke alarms provided by the embodiment of the application obtains the induction signals of a plurality of distributed smoke alarms in a target space area, wherein the distributed smoke alarms are in a communicated space area; under the condition that smoke induction signals of a plurality of distributed smoke alarms are received, acquiring generation time of each smoke induction signal and first identification information of a smoke alarm to which each smoke induction signal belongs; inquiring the position relation information of the smoke alarm to which each smoke induction signal belongs in design data based on the obtained identification information; and predicting the position information of the fire source according to the position relation information and the generation time of each smoke induction signal. Therefore, the position relation between each smoke alarm generating the smoke sensing signal and the fire source can be easily estimated by using the known distributed design data of the distributed smoke alarms and the time when smoke reaches the surrounding smoke alarms, so that the specific position of the fire source can be estimated. The problem that the capability of locating the specific position of a fire source is poor in a scene with the characteristics of large area, wide space and the like is avoided, and the situation that smoke is detected in the same space area to exceed a certain degree and then the fire is sprayed and extinguished in the space area without difference is avoided.
