[0002] At present, civil air defense underground space evacuation guidance faces many challenges. First, the complexity of underground space makes evacuation route planning difficult, which requires the use of precise algorithms to optimize evacuation routes. Secondly, the diversity of evacuees requires the system to be able to identify the special needs of different categories of people, such as the elderly, children, and the disabled, so as to provide personalized evacuation instructions.

[0042] The present application embodiment provides a method for guiding evacuation of underground civil air defense space. Figure 1 is a schematic diagram of the process of the civil air defense underground space evacuation guidance method provided by an embodiment of the present application, referring to Figure 1 The detailed description of the evacuation guidance method of the underground air defense space is as follows: Step 101: Acquire UWB tag information of target evacuees through a UWB positioning base station.

[0043] Exemplarily, the method is applied to an underground civil air defense space equipped with an underground civil air defense space evacuation guidance alarm system, and personnel entering the underground civil air defense space carry UWB devices.

[0044] Exemplarily, the UWB tag is a bracelet or work badge with UWB function; there are multiple UWB positioning base stations, and the signals of the UWB positioning base stations fully cover the underground civil air defense space.

[0045] Step 102: Determine the category of the target evacuee based on the UWB tag information.

[0046] For example, UWB tags with unique identification codes are distributed to different types of personnel (such as ordinary residents, medical staff, emergency rescue personnel, etc.). Tags can be made into easy-to-carry forms such as bracelets and cards. For example, easy-to-wear bracelet tags are designed for the elderly and children, and card-type tags with work information are designed for staff.

[0047] Step 103: Generate evacuation guidance information based on the category of the target evacuees.

[0048] Exemplarily, the civil air defense underground space includes concealed works; Exemplarily, step 103 may include: Based on the categories of the target evacuees, multiple concealed works that can be used for evacuation are determined.

[0049] Calculate the distance from the target evacuation personnel to each hidden project separately.

[0050] The target hidden project is determined based on the number of tags in each hidden project and the distance from the target evacuees to each hidden project.

[0051] The path from the target evacuees to the target concealed works is used as evacuation guidance information.

[0052] Exemplarily, determining the target hidden project according to the number of tags in each hidden project and the distance from the target evacuation personnel to each hidden project includes: Get the capacity of each hidden project and the number of tags in each hidden project.

[0053] According to the capacity of each hidden project and the number of tags in each hidden project, the hidden projects that are not fully staffed are determined; wherein, for each hidden project, if the number of tags in the hidden project reaches the capacity of the hidden project, the hidden project is fully staffed; if the number of tags in the hidden project does not reach the capacity of the hidden project, the hidden project is not fully staffed.

[0054] The hidden project with the shortest distance and not fully staffed shall be regarded as the target hidden project.

[0055] Exemplarily, this solution can monitor the number of people in the concealed project in real time, avoid evacuating the target personnel into the concealed project after the concealed project is full, and avoid casualties.

[0056] Exemplarily, the path from the target evacuees to the target concealed project is used as evacuation guidance information, including: All routes from the target evacuated personnel to the target concealed project are obtained and recorded as multiple first routes.

[0057] The number of UWB tags on each first route is obtained and recorded as a plurality of first values.

[0058] The first route corresponding to the minimum value of the first numerical value is used as the evacuation guidance information.

[0059] Exemplarily, selecting a route based on the first data can ensure that the routes to the target hidden project will not be crowded, which can improve the efficiency of evacuation and ensure that personnel can be evacuated into the hidden project as quickly as possible, avoiding casualties.

[0060] Step 104: Based on the evacuation guidance information, evacuation guidance is provided to the target evacuees, and when the movement trajectory of the target evacuees does not overlap with the guidance path in the evacuation guidance information, the multimedia alarm is controlled to sound an alarm.

[0061] Exemplarily, the multimedia alarm may include a laser light.

[0062] Laser lights are used to guide the evacuation of target personnel based on evacuation guidance information.

[0063] Exemplarily, the multimedia alarm device is provided with an LED display screen, which can play short psychological counseling videos and evacuation routes for personnel, and the ground projection can project the evacuation routes for personnel.

[0064] Exemplarily, the civil air defense underground space is also provided with a multi-network integrated differential transfer station and an underground space area controller. The multi-network integrated differential transfer station is connected to the underground space area controller, and the underground space area controller is connected to the multimedia alarm. The multi-network integrated differential transfer station is used to receive air defense alarm signals, and convert the air defense alarm signals into wired alarm signals, and send them to the underground space area controller. The underground space area controller is used to control the multimedia alarm to sound an alarm.

[0065] Exemplarily, the method may further include: After the multimedia alarm is controlled to sound an alarm, the location of the target evacuee is obtained again through the UWB positioning base station.

[0066] Based on the location of the target evacuees and the target concealed works, the path from the target evacuees to the target concealed works is re-determined, and the path is used as evacuation guidance information.

[0067] For example, the UWB positioning base station obtains the location of all tags in the underground space of civil air defense in real time, which helps to promptly detect whether personnel have abnormal movements during the process of evacuation (such as leaving the safe area due to panic) and take corresponding measures. For workers in concealed projects, they can be quickly deployed to the required location through the positioning system. For example, when someone in a certain area suddenly falls ill, the system can quickly locate nearby medical staff and notify them to go for treatment.

[0068] The above-mentioned civil air defense underground space evacuation guidance method determines the category of the target evacuees according to the UWB tag information of the target evacuees, generates different evacuation guidance information according to different categories, and evacuates the target evacuees of different categories. It can more reasonably evacuate the target evacuees of different categories, quickly relocate the refugees, and obtain the evacuation route without the need for complex algorithms, which can meet the needs of the scene where people need to be evacuated quickly.

[0069] For example, the civil air defense underground space evacuation guidance alarm system is as follows: Figure 2 As shown, it may include the above-mentioned multimedia alarm, UWB base station, UWB tag, underground space area controller and multi-network fusion type differential transfer station, and the multi-network fusion type differential transfer station includes a laser light and a loudspeaker.

[0070] For better understanding of this solution, Figure 3 As shown, a specific explanation is given.

[0071] When person M enters the underground air defense space, the UWB base station will obtain the UWB tag information carried by M, identify the category of M, and guide M into the corresponding area. Assuming that the hidden projects corresponding to M are C, F, and I, according to the above logic, the system will select the hidden project with the shortest distance and not full as the target and guide M there. Figure 3 As shown in the figure, C and F are full, so I is selected as the target hidden project. In the process of going to I, if M does not follow the guided path (S1 and S2) to go to I, the system will immediately alarm, relocate M's position, and guide a new path to I. In the process of M going to I, if two routes S1 and S2 appear, the system will evaluate the congestion level based on the number of tags on the routes S1 and S2, and select the route with less congestion as the final guidance path to ensure that M can quickly enter the hidden project.

[0072] In addition, the UWB tag also has the function of managing evacuees. If the evacuees fail to leave the hidden project in time, the system will trigger an alarm to remind the evacuees to re-enter the hidden project.

[0073] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
