TECHNICAL FIELD
[0001] The present application relates to the technical field of intelligent linkage control of intelligent fire-fighting equipment, and particularly relates to an intelligent linkage control system and method applied to intelligent fire-fighting equipment. BACKGROUND
[0002] With the continuous development of intelligent fire-fighting technology, the intelligent linkage control of fire-fighting equipment is increasingly crucial in fire prevention and extinguishing. As a core link of fire emergency disposal, the timeliness, collaborative efficiency and capacity adaptability of fire-fighting equipment linkage directly affect the fire extinguishing effect.
[0003] However, the traditional fire-fighting equipment linkage mode often faces the following problems when dealing with complex fire scenes, multi-device collaborative operation and dynamic capacity adjustment. First, the linkage response efficiency is low and relies on manual scheduling. When facing multiple types and quantities of fire-fighting equipment, the coordination lags behind. When a fire occurs, there are many types of fire-fighting equipment to be enabled on site. The traditional linkage mode relies on manual judgment of equipment combination. When facing massive equipment information, scheduling may not be timely. Second, there is a lack of collaborative capability assessment, and the multi-device linkage efficiency cannot be quantified. The traditional method relies on experience to judge the effect of equipment linkage, and a scientific capability assessment model has not been established. It is difficult to calculate the actual fire extinguishing capacity of multi-device collaboration. The problem of "insufficient equipment configuration to cover fire extinguishing demand" may occur. In addition, the linkage strategy lacks a dynamic adjustment mechanism and cannot optimize the equipment combination in real time according to the fire area to be extinguished. Once the equipment combination is determined in the traditional linkage mode, it is difficult to adjust quickly. The equipment cannot be supplemented in time according to the difference between the actual fire extinguishing time and the expected threshold, which limits the fire extinguishing efficiency. SUMMARY

The device adjustment unit is used to determine that the fire-fighting devices enabled in the current fire-fighting occasion meet the use scenario of the current fire-fighting occasion when the set threshold is greater than or equal to the calculated time length consumed by the fire-fighting devices enabled in the current fire-fighting occasion for extinguishing the area to be extinguished, and to increase the number of the fire-fighting devices to be enabled when the set threshold is less than the calculated time length consumed by the fire-fighting devices enabled in the current fire-fighting occasion for extinguishing the area to be extinguished.
[0028] In an embodiment: a certain area is simulated to catch fire, and multiple types of fire-fighting devices need to be enabled for cooperative fire extinguishing. All the fire-fighting devices to be enabled in the area are obtained, including spraying devices, fire hydrants, smoke exhaust devices, etc. The operation data of each device in a standard fire extinguishing scenario is collected to evaluate the fire-fighting capacity of each device, i.e., according to the time consumed by the device for extinguishing a standard area, the extinguishing area covered by the device per unit time is calculated, and then the proportion of the capacity of each device in the linkage system is determined in combination with the overall situation of all the devices to form a device capacity list. Subsequently, for the set of fire-fighting devices to be linked, the fire-fighting capacity values of the fire-fighting devices are gradually merged into two groups according to the fire-fighting capacity values of the fire-fighting devices, the proportion of the total capacity value of each group in the total capacity value of all the devices is calculated, the maximum value among them is taken as the maximum fire-fighting capacity coefficient, and the linkage attenuation coefficient is calculated based on the maximum fire-fighting capacity coefficient. When a device needs to be added, the same logic is recursively calculated, i.e., the comprehensive capacity of the already linked devices is taken as a whole, and the maximum proportion and the attenuation coefficient are calculated again by grouping the whole with the new device, and then the total capacity value when more devices are linked is obtained. The predicted fire extinguishing time is obtained in combination with the area to be extinguished in the simulated fire and the fire-fighting capacity of all the linked devices calculated above. Meanwhile, according to the fire safety specification of the park, the expected longest fire extinguishing time threshold in this scenario is set. After comparing the predicted time consumption with the threshold, it is found that the predicted time consumption of the current device is slightly longer than the threshold, and an instruction is immediately issued to add a fire-fighting device. After the new device is added, the processes of capacity evaluation, grouping calculation and comprehensive capacity correction are performed again, and finally the predicted time consumption is lower than the threshold, and it is determined that the current combination of devices meets the fire extinguishing demand, and the linkage control process is completed.
