The term "coupled" as used herein includes both direct and indirect coupling (coupling), unless otherwise indicated.
The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
As shown in fig. 1, the emergency self-control system of the fire-fighting fan in the present specification comprises: the fire fighting device comprises a fire fighting wind generating set, a smoke detection unit, a fire fighting gas storage device and a master control device.
Wherein, fire control fan group is configured as: comprises a plurality of (more than one) fire fans which are distributed in the fire protection area. The fire-fighting area in the specification can be a factory area, an underground garage, an office building and the like, and can be used as the fire-fighting area in the specification at a place where a plurality of fire-fighting fans can be arranged. The fire-fighting area is an area where fire protection is required, and no fire or smoke is required in such an area.
A smoke detection unit configured to: the fire control fan comprises a first unit arranged in an air duct of the fire control fan and a second unit arranged on one side of the fire control fan communicated with the outside. That is, each fire fan includes a first unit and a second unit. Alternatively, the first unit and the second unit are identical, but the setting positions of the two are different. Further alternatively, in case the fire fans of the first and second units are not operated in order to save control resources, the first and second units are not operated. In the related art, a device for detecting the smoke content in a gas may be used as the smoke detection unit in the present specification.
A fire gas storage device configured to: fire-fighting gas is stored and connected with the fire-fighting fan through a pipeline which can be communicated. The gas which can be used for fire fighting and for reducing the spread of fire in the related art can be used as the fire fighting gas in the present specification, for example, carbon dioxide or the like.
And a master control device configured to: and the fire-fighting fan and the smoke detection unit are connected. And when a fire event occurs, determining a first fan based on the received data acquired by the smoke detection unit. The first fan in the specification is a fire-fighting fan (that is, the first fan is actually performing smoke discharging operation) in which the smoke concentration shown by the data collected by the first unit is greater than the smoke concentration shown by the data collected by the second unit corresponding to the fire-fighting fan to which the first fan belongs, and the smoke concentration shown by the data collected by the second unit corresponding to the first fan is greater than a preset concentration threshold (that is, the environment into which the smoke discharged by the first fan enters also contains larger smoke). And controlling pipeline communication between the first fan and the fire-fighting gas storage device so that the first fan blows the fire-fighting gas into the fire-fighting area.
When the first fan performs smoke discharging operation, smoke is discharged into another space with larger smoke concentration. That is, the first fan in this specification is a fire-fighting fan which is located at or near the location of a fire and has a limited smoke discharging effect. The first fan is converted into the fire extinguishing fan by the exhaust fan, so that the first fan is prevented from doing idle work while the fire extinguishing efficiency is improved, and the spread of fire is prevented.
According to the method, the positions of disasters are determined by using the setting positions of the fire fans and smoke conditions in the internal and external environments of the corresponding fire areas of the ventilating ducts, and on the basis, the work of the fire fans arranged at different positions of the fire areas relative to the disasters is controlled, and the process does not need excessive manual intervention, so that manual transfer is realized by means of technology. In addition, the process is matched with the actual situation of the fire-fighting area, thereby being beneficial to the targeted treatment of disasters and avoiding the continuation of the disasters.
In an alternative embodiment of the present description, the concentration threshold is an empirical value. In another alternative embodiment of the present specification, the concentration threshold is inversely related to a distribution density of the fire fans in the fire protection area.
The specific fire event can be determined according to the service requirement. For example, a fire event is determined to occur when an open fire occurs; as another example, smoke is present, a fire event is determined to occur. That is, the fire event may be determined manually or automatically. In an alternative embodiment of the present disclosure, the fire protection fan set is periodically (e.g., one cycle every 20 minutes) controlled to draw gas from the fire protection area, and the fire protection event is determined to occur if the data collected by any of the first units indicates a smoke concentration greater than the concentration threshold. In another optional embodiment of the present disclosure, the smoke detection unit further includes a third unit, the third unit being disposed in the fire protection area instead of the fire protection blower, and if the data collected by the third unit indicates that the smoke concentration is greater than the concentration threshold, the fire protection event is determined to occur, and the third unit is always in an operating state.
Even though the fire can be prevented from spreading by the method in the present specification, in actual situations, the fire in the fire-fighting area may not be effectively controlled, and a position other than the position corresponding to the first fan should be examined. In an alternative embodiment of the present description, the alternative blower is determined based on the received data collected by the smoke detection unit when a fire event occurs. The alternative fan is a fire-fighting fan of which the smoke concentration shown by the data collected by the first unit is not more than the smoke concentration shown by the data collected by the second unit corresponding to the fire-fighting fan to which the alternative fan belongs, and the smoke concentration shown by the data collected by the second unit corresponding to the alternative fan is not more than a preset concentration threshold. That is, the alternative blower in this specification is a fire blower whose location of the proximity to the fire source is not yet clear. The rotational speed of the alternative blower is increased when the alternative blower draws gas from the fire area, so as to draw the smoke gas in the fire area to the vicinity of the alternative blower as much as possible, and reduce the smoke concentration in the fire area. If the gas containing the smoke cannot be extracted, the alternative fan is far away from the fire area. If the smoke concentration represented by the data acquired by the first unit corresponding to the alternative fan is still not greater than the smoke concentration represented by the data acquired by the second unit corresponding to the alternative fan, and the smoke concentration represented by the data acquired by the second unit corresponding to the alternative fan is still not greater than a preset concentration threshold, controlling the alternative fan to blow gas into the fire-fighting area. Because the alternative fan is far away from the fire source, people can possibly escape to the position where the alternative fan is located, and through the method in the specification, the smoke can be prevented from spreading to the position where the alternative fan is located, and the safety of the people can be guaranteed.
In addition, after the rotating speed of the alternative fan when the gas extracted from the fire-fighting area is increased, if the smoke concentration represented by the data collected by the corresponding first unit is larger than the smoke concentration represented by the data collected by the corresponding second unit, and the smoke concentration represented by the data collected by the corresponding second unit is larger than a preset concentration threshold value, the alternative fan is determined to be the second fan. That is, the second fan is located at a position other than the position of the fire source, but is located closer to the position of the fire source, and the second fan may be converted into the first fan. At this time, the current rotating speed (namely, the rotating speed after the speed is increased) of the second fan is kept, so that the smoke concentration at the fire source position is reduced, and the escape of personnel is facilitated.
After the first fan is determined, analyzing the data acquired by the smoke detection unit corresponding to the first fan in real time. The first fan is controlled to extract gas from the fire-fighting area in a staged mode, and after a certain period of time (the duration can be a preset value), the first fan is controlled to blow fire-fighting gas into the fire-fighting area. If the difference between the smoke concentration indicated by the data collected by the first unit corresponding to the first fan and the smoke concentration indicated by the data collected by the second unit corresponding to the first fan is not greater than a preset difference threshold (the difference threshold may be an empirical value), and if the smoke concentration indicated by the data collected by the second unit corresponding to the first fan is greater than the preset concentration threshold (indicating that fire exists in a fire-fighting area except for the location of the first fan, that is, the first fan is not unique, only smoke is caused to exist in a smoke-discharging pipeline or an external environment), the rotation speed of the first fan is increased, so that the efficiency of blowing fire-fighting gas into the fire-fighting area is increased. Meanwhile, in consideration of the fact that the fire disaster has progressed to a serious stage, after the rotation speed of the first fan is increased, the pipeline communication between the second fan and the fire control gas storage device is controlled, so that the second fan blows the fire control gas into the fire control area, and the rotation speed of the second fan is higher than that of the first fan, so that higher air pressure is provided for the fire control area where the second fan is located, and the fire disaster is further prevented from spreading.
In addition, after the rotating speed of the first fan is increased, in the fire-fighting fans except the first fan and the second fan, the smoke concentration shown by the data acquired by the first unit and the second unit is not larger than a preset concentration threshold value, and the smoke concentration is used as a third fan. And controlling the third fan to stop rotating. The third fan is the area where no fire condition exists, the third fan is controlled to stop rotating, and the third fan and the smoke exhaust pipeline can be isolated to a certain extent, so that smoke is prevented from entering the fire control area where the third fan is located from the smoke exhaust pipeline. And after the third fans are controlled to stop rotating, periodically (the period time can be a preset value) controlling the third fans to extract gas from the fire-fighting area, and if the smoke concentration represented by the data collected by the first unit corresponding to any one of the third fans is greater than the concentration threshold (indicating that the fire is not effectively controlled and the risk of spreading to the position of the third fans exists), controlling the third fans to extract gas from the fire-fighting area.
After controlling the third blower to draw gas from the fire area for a specified period of time, the first blower is re-determined to re-determine the spread of the fire in the fire area. And if the re-determined proportion of the first fans to all the fire-fighting fans is larger than a preset proportion threshold value (indicating that the fire is in a more difficult-to-control stage), controlling pipeline communication between all the fire-fighting fans and the fire-fighting gas storage device so that all the fire-fighting fans blow the fire-fighting gas into the fire-fighting region.
Thereafter, there may also be a plurality of instances of re-determining the first fan to continually update the judgment of the fire spread condition. The duration of the specified time period is inversely related to the number of the first fans determined at the current moment, that is, as the number of the first fans increases, the first fans are updated more frequently. If the fire is controlled gradually and the fire is reduced, the frequency reduction of the first fan is determined again. The proportional threshold in this specification is inversely related to the duration of the specified time period. Considering that the longer the duration is, the greater the possibility that the fire is controlled is, the proportion threshold is reduced, the condition of the fire can be judged from finer granularity, the proportion threshold is adjusted at any time, and the accuracy of fire judgment is improved.
