Potassium ion safe aerosol fire extinguishing technology is currently mainly used in nine major industry sectors: homes, military and police, communications, transportation, new energy, laboratories, power, petrochemicals, and machinery. The technology is extended to include portable fire extinguishing sticks, small fire extinguishing devices, and intelligent fire extinguishing devices. Future applications will extend to the construction engineering field, developing customized fire extinguishing solutions based on different application scenarios to safeguard the vigorous development of emerging industries and provide market space for the upgrading and transformation of traditional industries.

[0003] Currently, fire monitoring in elevator machine rooms mainly relies on smoke detectors and heat detectors installed in the machine room.

[0041] Example 8: Based on Example 1, this embodiment of the invention provides a fire safety control system for elevator machine rooms based on potassium ion aerosol fire suppression, including an adjustment module comprising: The model building unit is used to construct an elevator machine room-fire extinguishing device model based on the spatial layout of the elevator machine room and the structural layout of the potassium ion aerosol fire extinguishing device. Combined with the fire size change curve, a dynamic fire simulation model of the elevator machine room is obtained using the fire model construction method. An effect addition unit is used to determine the correspondence between the real-time control parameters of the potassium ion aerosol fire extinguishing device and the potassium ion aerosol fire extinguishing characteristics, and to add dynamic display features of the fire extinguishing effect to the location of the fire extinguishing device in the dynamic fire simulation model using the correspondence. The parameter determination unit is used to determine the current fire severity and fire severity change characteristics based on the fire severity change curve, determine the initial control parameters of the potassium ion aerosol fire extinguishing device based on the fire severity change characteristics, and correct the initial control parameters based on the fire severity change characteristics to obtain the target control parameters. The simulation unit is used to determine the dynamic display characteristics of the target fire extinguishing effect in the dynamic fire simulation model based on the target control parameters, and to simulate fire extinguishing in the elevator machine room to obtain the theoretical fire extinguishing effect. The parameter adjustment unit is used to determine whether the theoretical fire extinguishing effect meets the preset fire extinguishing effect requirements; If so, the target control parameters are used as the fire extinguishing control parameters of the potassium ion aerosol fire extinguishing device, and fire extinguishing is carried out according to the fire extinguishing control parameters; Otherwise, after correcting the target control parameters upward according to the preset range, the potassium ion aerosol fire extinguishing device is immediately activated to extinguish the fire, and the real-time fire intensity change characteristics are obtained. When the real-time fire intensity change characteristics show an upward trend, the target control parameters are corrected upward again; otherwise, the target control parameters are corrected downward until the fire is extinguished.

[0042] In this embodiment, after obtaining the target control parameters, a rapid simulation is performed to obtain the theoretical fire extinguishing effect, which can ensure that the initial fire extinguishing parameters are more in line with the actual situation and guarantee the fire extinguishing effect.

[0043] In this embodiment, the dynamic display feature of the fire extinguishing effect can be presented differently according to changes in control parameters.

[0044] The beneficial effects of the above design scheme are as follows: Based on the spatial layout of the elevator machine room and the structural layout of the potassium ion aerosol fire extinguishing device, an elevator machine room-fire extinguishing device model is constructed. Combined with the fire magnitude change curve, a dynamic fire simulation model of the elevator machine room is obtained using a fire model construction method. The correspondence between the real-time control parameters of the potassium ion aerosol fire extinguishing device and the characteristics of potassium ion aerosol fire extinguishing is determined. Using this correspondence, dynamic fire extinguishing effect display features are added to the location of the fire extinguishing device in the dynamic fire simulation model, providing a model basis for fire extinguishing simulation. Then, based on the fire magnitude change curve, the current fire severity and fire severity change characteristics are determined. The initial control parameters of the potassium ion aerosol fire extinguishing device are determined based on the fire severity, and the initial control parameters are corrected based on the fire severity change characteristics to obtain target control parameters, ensuring the superiority of the target control parameters. Based on the target control parameters, the target fire extinguishing device in the dynamic fire simulation model is determined. The system dynamically displays the fire extinguishing effect, simulating fire extinguishing in an elevator machine room to obtain the theoretical fire extinguishing effect. This is used to determine whether the theoretical fire extinguishing effect meets the preset fire extinguishing requirements. If so, the target control parameters are used as the fire extinguishing control parameters for the potassium ion aerosol fire extinguishing device, and fire extinguishing is carried out according to these parameters. Otherwise, the target control parameters are adjusted upwards by a preset range, and the potassium ion aerosol fire extinguishing device is immediately activated to extinguish the fire. Real-time fire intensity changes are acquired, and if the real-time fire intensity changes show an upward trend, the target control parameters are adjusted upwards; otherwise, they are adjusted downwards until fire extinguishing is complete. By first simulating the fire extinguishing and obtaining the theoretical fire extinguishing effect, the initial fire extinguishing parameters are more closely aligned with the actual situation, ensuring the fire extinguishing effect. Real-time parameter adjustments are made during the fire extinguishing process to ensure the real-time fire extinguishing effect. Through a combination of pre-simulation and in-process adjustment, optimal fire extinguishing is achieved.

[0045] Example 9: Based on Example 8, this embodiment of the invention provides a fire safety control system for elevator machine rooms based on potassium ion aerosol extinguishing, including a parameter determination unit, comprising: The upward correction unit is used to correct the initial control parameters upward when the fire severity change characteristics show an upward trend, so as to obtain the target control parameters. The downward correction unit is used to correct the initial control parameters downward when the fire severity change characteristics show a downward trend, so as to obtain the target control parameters.

[0046] In this embodiment, adjusting the initial control parameters upwards increases the fire extinguishing effectiveness of the fire extinguishing device, while adjusting them downwards decreases the fire extinguishing effectiveness.

[0047] The beneficial effects of the above design scheme are: based on the characteristics of fire intensity changes, the initial control parameters are corrected to obtain the target control parameters, thus ensuring the superiority of the target control parameters.
