It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments described herein can be practiced in sequences other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus that encompasses a series of steps or units and need not be limited to those explicitly listed.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all of the embodiments.

In order to solve the problem of poor fire source positioning capabilities when using smoke sensors in large-area and large-space scenarios, please refer to Figure 1, which is a schematic flow chart of a safety monitoring method based on distributed smoke alarms provided in an embodiment of the present application. , specifically it may include: steps S110, S120, S130 and step S140.

S110, obtain sensing signals of multiple distributed smoke alarms in the target space area, where multiple distributed smoke alarms are in a connected space area;

For example, the above-mentioned multiple distributed smoke alarms can be located in the same open workspace or a relatively open exhibition hall, etc., which is not limited here.

For example, the above-mentioned connected space area means that air or smoke can circulate freely in the space station.

S120, when receiving smoke sensing signals from multiple distributed smoke alarms, obtain the generation time of each smoke sensing signal and the first identification information of the smoke alarm to which each smoke sensing signal belongs;

For example, the smoke alarm generates a smoke sensing signal when smoke is detected or the smoke reaches a certain concentration. The above-mentioned first identification information can be used to distinguish the smoke alarm.

S130, query the position relationship information of the smoke alarm to which each smoke sensing signal belongs in the design data based on the obtained identification information;

For example, the first identification information itself can also be made to carry location information, so as to obtain the location relationship information of the smoke alarm to which each smoke sensor signal belongs.

S140: Predict fire source location information based on the location relationship information and the generation time of each smoke sensing signal.

For example, in an indoor environment without considering the influence of external airflow, the generation time of the smoke sensor signal, that is, the time when the smoke alarm detects smoke or the smoke reaches a certain concentration, is different, which can indirectly reflect the relative intensity of the fire source to the surrounding environment. Smoke alarm position proportional relationship. The relationship between the location of the fire source and the location of these smoke alarms that detect smoke can be determined to a certain extent.

In summary, the safety monitoring method based on distributed smoke alarms provided by the embodiments of the present application obtains the induction signals of multiple distributed smoke alarms in the target space area, where the multiple distributed smoke alarms are in Connected spatial areas; when receiving smoke sensing signals from multiple distributed smoke alarms, obtain the generation time of each smoke sensing signal and the first identification information of the smoke alarm to which each smoke sensing signal belongs ; Query the position relationship information of the smoke alarm to which each smoke sensor signal belongs in the design data based on the obtained identification information; predict the fire source based on the position relationship information and the generation time of each smoke sensor signal location information. From this, the known distributed design data of distributed smoke alarms and the time for smoke to reach surrounding smoke alarms can be used to easily infer the positional relationship between each smoke alarm that generates smoke sensing signals and the fire source, so as to Determine the specific location of the fire source. It avoids the problem of poor ability to locate the specific location of the fire source in scenes with large areas and open spaces, as well as the indiscriminate detection of smoke beyond a certain level in the same space area caused by this problem. Sprinkler fire extinguishing occurs in the space area. This avoids unnecessary waste of resources and damage to electronic equipment and other property in relatively safe areas caused by indiscriminate spraying.

According to some embodiments, it also includes:

Determine second position information of the target sprinkler unit around the fire source based on the fire source position information;

The spray pressure of the target spray unit is calculated according to the second position information and the fire source position information, wherein the spray pressure is positively related to the spray distance.

For example, the main spray area reached by the spray liquid can be inferred by adjusting the spray pressure and combined with the principle of only falling bodies. It can be determined which spray units are turned on based on the fire source location information, and based on each spray unit and the prediction, the According to the distance from the fire source position, adjust the spray pressure of the spray unit to ensure 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 distributed circumferentially, and the spray pressure is inversely related to the number of connections of the spray ports of each spray unit. The spray pressure Positively related to the number of closures of the spray ports of each spray unit, the method also includes:

The number and location of the spray ports that the target spray unit needs to be connected are determined based on the second position information of the target spray unit and the fire source position information.

For example, the spray distance can be further adjusted by the number of spray ports of the spray unit, instead of just relying on the valve of the spray unit or even the main valve to which multiple spray units belong. In this way, the spray distance of the spray unit can be adjusted The spray distance adjustment is more flexible and further increases the effective spray range of the spray unit in one direction or certain directions. It is convenient to concentrate the spray liquid of more spray units on the far away fire source positions.

According to some embodiments, any position of the target space area is within the maximum spray range of at least two surrounding spray units, and the second position information based on the target spray unit and the fire source position The information determines the number and location of the spray ports that need to be connected to the target spray unit, including:

The number and location of the sprinkler ports that each target sprinkler unit needs to be connected are determined based on the second position information of each target sprinkler unit and the fire source position information, so that at least two of the target sprinklers can be connected. The unit's main spray streams overlap at the location of the fire source.

For example, when the predicted fire source position is between spray unit a and spray unit b and closer to b, then the pressure of the liquid sprayed by the spray unit can be adjusted by adjusting the valve of the spray unit. To control the position of the main spray water flow, the positions of the main spray water flow of the spray unit a and the spray unit b overlap at the fire source position, so that the fire source position can be more effectively extinguished. After controlling the number and location of the circumferential spray ports of spray unit a and spray unit b, the position of the main spray water flow of spray unit a and spray unit b can be further positioned at the fire source. Overlapping positions, for example, open the spray port on the side of spray unit a facing spray unit b to close other ports, and open the spray port on the side of spray unit b facing spray unit a to close other ports, and you can The positions of the main spray water flows of a and b at this time are adjusted by adjusting the number of ports opened by a and b, so that the main spray water flows of the two target spray units overlap at the fire source position. On the one hand, the water pressure and spray distance can be adjusted without the help of valves. On the other hand, the spray distance can be adjusted by combining valves and spray ports, which can make the effective range of the spray distance wider. Even the sprinkler units d and e that are far away from the fire source can participate in the fire extinguishing operation at the fire source.

According to some embodiments, it also includes:

According to the location relationship information and the generation time of each of the smoke sensing signals, predict the fire spread trend, where the spread trend includes the spread direction;

Based on the spreading direction and the design data, a smoke pre-sensing signal is generated in advance in a target smoke alarm that has not yet generated a smoke sensing signal or a target sprinkler unit around the target smoke alarm is turned on in advance.

For example, when smoke alarm a, smoke alarm b, and smoke alarm c arranged along the same first direction generate smoke pre-sensing signals at one time, it can be determined that the fire spreads along the first direction. Then, a smoke pre-sensing signal can be generated in the smoke alarm d that has not yet generated a smoke sensing signal along the first direction or the target sprinkler unit around the smoke alarm d can be turned on in advance.

According to some embodiments, it also includes:

Predict the fire spread trend based on the location relationship information and the generation time of each smoke sensing signal, where the spread trend includes a spread path;

Based on the spreading path and the design data, a smoke pre-sensing signal is generated in advance in a target smoke alarm that has not yet generated a smoke sensing signal or a target sprinkler unit around the target smoke alarm is turned on in advance.

Smoke detector:

In the case where the spreading trend includes a spreading path, the target smoke alarm is a smoke alarm along the spreading path that has not yet generated a smoke sensing signal.
