Specifically, when a fire disaster occurs, people may be distributed more dispersedly, if people in different positions adopt the same green evacuation channel, people far away from the green evacuation channel may have safety risks, so that the electronic equipment acquires the people distribution information in the current building, determines the personnel position information based on the people distribution information, traverses all the green evacuation channels based on the personnel position information, determines a first personnel evacuation channel, and the first personnel evacuation channels corresponding to people in different positions may be different; so as to find the most suitable escape passage for people in different positions.

In step S102, determining illumination color information of the evacuation channel based on the fire level parameter specifically includes: acquiring safety distance information corresponding to the fire grade parameters; acquiring first target distance information corresponding to a plurality of evacuation channels and fire areas respectively; if any one of the first target distance information does not exceed the safety distance information, controlling illumination color information of the evacuation channel corresponding to any one of the first target distance information to be red, and determining a red evacuation channel; if any one of the first target distance information exceeds the safety distance information, the illumination color information of the evacuation channel corresponding to any one of the first target distance information is green, and the green evacuation channel is determined.
In the embodiment of the application, the evacuation channels comprise a plurality of evacuation channels; the safety distance information indicates distance information of evacuation channels and fire areas which do not affect crowd escape, and the safety distance information corresponds to fire grade parameters one by one.
Specifically, the electronic device obtains the safety distance information corresponding to the fire grade parameter, the higher the fire grade parameter is, the more remote the corresponding safety distance information is, for example, when the fire grade parameter is the B grade, the corresponding safety distance information is 10 meters, and when the fire grade parameter is the A grade, the corresponding safety distance information is 15 meters; then the electronic equipment acquires first target distance information corresponding to a plurality of evacuation channels and fire areas respectively, traverses the first target distance information, screens the first target distance information and the safety distance information, if any first target distance information does not exceed the safety distance information, the distance between the evacuation channel corresponding to any first target distance information and the fire areas is relatively close, and if people escape from the evacuation channel with relatively high probability, safety accidents can occur, so the electronic equipment controls the illumination equipment of the evacuation channel, the color of the illumination equipment of the evacuation channel is changed into red, and the evacuation channel is defined as a red evacuation channel; if any one of the first target distance information exceeds the safety distance information, the fact that the evacuation channel corresponding to any one of the first target distance information is far away from the fire area is indicated, the influence of the fire area is small, escape from the evacuation channel is safe, therefore the electronic equipment controls the illumination equipment of the evacuation channel, the color of the illumination equipment of the evacuation channel is modified to be green, and the evacuation channel is defined to be a green evacuation channel; therefore, according to the current fire situation, a safe and appropriate evacuation channel is intelligently selected for people to escape, and dangerous evacuation channels are reminded.
In step S103, determining a first person evacuation channel based on the crowd distribution information and the illumination color information specifically includes: determining personnel location information based on the crowd distribution information; determining second target distance information between the personnel position information and the green evacuation channel based on the personnel position information; if the second target distance information does not exceed the preset distance information, determining that the green evacuation channel corresponding to the second target distance information is the first personnel evacuation channel.
Specifically, after the electronic device obtains the crowd distribution information, the crowd distribution may be relatively scattered, and for the crowd with large scattering degree, the corresponding evacuation channels are different, so the electronic device divides the crowd distribution information according to the number of the evacuation channels and the distance between the evacuation channels, determines the personnel position information, the personnel position information can include a plurality of personnel, then calculates second target distance information corresponding to each personnel position information and a plurality of green evacuation channels by taking each personnel position information as an origin, compares the second target distance information with preset distance information, and if any second target distance information does not exceed the preset distance information, indicates that the escape distance of the green evacuation channel corresponding to any second target distance information is relatively short compared with the personnel, and therefore the electronic device takes the green evacuation channel as the first personnel evacuation channel.
Further, if any one of the second target distance information exceeds the preset distance information, the escape distance is far from the person for the green evacuation channel corresponding to the any one of the second target distance information, so that the electronic equipment does not determine the first person evacuation channel, and continues to compare the other second target distance information, if the comparison is completed, the electronic equipment still cannot determine the first person evacuation channel, and then screens the plurality of second target distance information, and takes the green evacuation channel corresponding to the second target distance information with the smallest distance as the first person evacuation channel of the person; therefore, according to crowd distribution information, the most suitable evacuation channel is intelligently selected for each person.
In step S104, if the people flow information exceeds the preset people flow information, determining a second people evacuation channel specifically includes: if the people flow information exceeds the preset people flow information, screening all green evacuation channels of the current floor; taking a green evacuation channel closest to the first personnel evacuation channel as a target green evacuation channel, and controlling the illumination color of the first personnel evacuation channel to be changed from green to yellow; and determining the target green evacuation channel as a second personnel evacuation channel.
Specifically, after the electronic device determines the first personnel evacuation channel, if the number of people to be evaded in the single evacuation channel is too large, the electronic device is not beneficial to escape and even can generate a trampling accident, so that the electronic device detects the people flow information of the first personnel evacuation channel in real time, if the people flow information of the first personnel evacuation channel does not exceed the preset people flow information, the current first personnel evacuation channel does not reach the load limit yet, and therefore, the electronic device does not respond, if the people flow information of the first personnel evacuation channel exceeds the preset people flow information, the people flow information of the current first personnel evacuation channel already reaches the load limit, and if people continue to escape to the evacuation channel, the people can possibly be overcrowded due to the evacuation channel, so that trampling accidents occur in the evacuation channel, the electronic device screens other green evacuation channels in the current floor, meanwhile, controls the lighting device of the first personnel evacuation channel to be changed into yellow, takes the green evacuation channel closest to the current first personnel evacuation channel as a target green evacuation channel, and determines the target green evacuation channel as a second personnel evacuation channel; therefore, according to the escape situation of the crowd, the situation that the crowd is excessively concentrated on a certain green evacuation channel is avoided, and the escape success rate is improved.
After the electronic equipment determines that the second people evacuation channel is finished, people flow information detection is also needed for the second people evacuation channel, and if the second people evacuation channel also exceeds the preset people flow information, a third people evacuation channel is continuously determined; and because the meaning of the color of the lighting equipment cannot be correctly understood by the existing personnel, voice broadcasting prompt is carried out when the illumination color information of the lighting equipment is changed.
Further, the method further comprises: determining an average spread rate of the fire based on the fire rating parameter; determining a predicted fire spread area based on the average spread rate; acquiring third target distance information of a predicted fire spreading area and a green evacuation channel; if the third target distance information does not exceed the corresponding safety distance information, determining the predicted fire spreading time based on the predicted fire spreading area and feeding back and displaying the predicted fire spreading time.
In the embodiment of the application, the predicted fire spreading area is the predicted fire spreading area in the next time period.
Specifically, after the electronic equipment determines the personnel evacuation channels, the spreading speed of the current fire is detected in real time based on the current fire grade parameter, the average spreading speed is calculated based on the fluctuation range of the spreading speed, then the predicted fire spreading area is determined based on the average spreading speed, then third target distance information corresponding to the predicted fire spreading area and the plurality of green evacuation channels is calculated, and if no personnel escape is detected in any green evacuation channel, any green evacuation channel is removed and calculation is not performed.
Further, based on the predicted fire spreading area, the predicted fire grade parameter is redetermined, and if the predicted fire grade parameter changes, the corresponding safety distance information also changes; if any third target distance information exceeds the corresponding safety distance information, the electronic equipment is indicated to be still in a safety state, so that the electronic equipment does not respond at all, if any third target distance information does not exceed the corresponding safety distance information, the electronic equipment is indicated to be about to wave the green evacuation channel corresponding to any third target distance information, so that the electronic equipment determines the predicted fire spreading time based on the predicted fire spreading area, namely the time that the fire is about to wave the green evacuation channel, and finally performs countdown feedback display on the predicted fire spreading time to remind people of evacuation time; therefore, the success rate of escape is improved by predicting the spreading degree of the current fire.
