The laboratory environment monitor 101 can specifically be a sensor set in the laboratory environment, including: a temperature sensor, a humidity sensor, a living body presence sensor, an electrical safety sensor, a smoke monitoring sensor, a video number recognition sensor, a thermal imaging high temperature monitoring sensor, a video fireworks recognition sensor, a video instrument pointer recognition sensor, a gas concentration monitoring sensor, and a gas supply pressure, flow monitoring sensor, etc. The temperature sensor is used to monitor the temperature characteristics in the laboratory environment and output the temperature data in the laboratory environment; the humidity sensor is used to monitor the humidity characteristics in the laboratory environment and output the humidity data in the laboratory environment; the living body presence sensor is used to monitor whether there are living targets in the laboratory environment and output the data on whether there are living targets in the laboratory environment; the power safety sensor is used to monitor whether the power use in the laboratory environment is safe and output the power safety data in the laboratory environment; the smoke monitoring sensor is used to monitor the smoke characteristics in the laboratory environment and output the smoke data; the video number recognition sensor is used to monitor the video image data in the laboratory environment and output the number of living people data in the video image data; the thermal imaging high temperature monitoring sensor is used to monitor the temperature characteristics of the equipment in the laboratory environment and output the temperature data of the equipment; the video fireworks recognition sensor is used to monitor the fireworks characteristics in the laboratory environment and output the fireworks data in the video image; the video instrument pointer recognition sensor is used to monitor the pressure characteristics of the equipment in the laboratory environment and output the pressure data of the equipment; the gas concentration monitoring sensor is used to monitor the gas concentration characteristics in the laboratory environment and output the gas concentration data; the gas supply pressure and flow monitoring sensor is used to monitor the gas pressure characteristics and gas flow characteristics in the laboratory environment and output the gas pressure data and gas flow data.

[0147] The laboratory environment data collector 102 is used to collect the laboratory environment monitoring data and send the environment monitoring data to the laboratory safety event locator 103. The laboratory environment monitoring data can specifically be the laboratory temperature data, humidity data, smoke data, high temperature data, fireworks data, instrument pressure data, gas concentration data, gas supply pressure data, gas supply flow data, etc. In specific implementation, the environment monitoring data can be obtained through a monitor set in the laboratory environment. The monitor can specifically be a sensor. For example, the above-mentioned environment monitoring data can be obtained through corresponding temperature sensors, humidity sensors, smoke monitoring sensors, thermal imaging high temperature monitoring sensors, video fireworks recognition sensors, video instrument pointer recognition sensors, gas concentration monitoring sensors, and gas supply pressure and flow monitoring sensors.

[0148] After the laboratory environment data collector 102 collects the environment monitoring data of the laboratory, the environment monitoring data is sent to the laboratory safety event locator 103. The laboratory safety event locator 103 is used to determine whether there is abnormal environment monitoring data in the environment monitoring data based on the environment monitoring data. If there is abnormal environment monitoring data in the environment monitoring data, the type data and abnormal location point data of the safety event that occurred in the laboratory are obtained according to the environment monitoring data, and the type data and abnormal location point data of the safety event are sent to the display screen controller 104. It should be noted that after obtaining the environment monitoring data, the laboratory safety event locator 102 will determine whether there is abnormal environment monitoring data in the environment monitoring data, such as whether the temperature data is abnormal, whether the fireworks data is abnormal, whether the gas concentration is abnormal, and whether the pressure is abnormal. If there is abnormal environment monitoring data, the type data and abnormal location point data of the safety event that occurred in the laboratory are obtained according to the environment monitoring data. When obtaining the type data and abnormal location point data of safety incidents occurring in the laboratory according to the environmental monitoring data, the laboratory safety incident locator 103 can obtain the type data and abnormal location point data of safety incidents occurring in the laboratory based on the environmental monitoring data through a fireworks multi-factor recognition algorithm, a toxic and harmful gas leakage multi-factor recognition algorithm, a flammable and explosive object leakage multi-factor recognition algorithm, and a high-temperature and high-pressure container loss of control abnormality multi-factor recognition algorithm.

[0149] In a specific implementation, the method of obtaining type data of safety events occurring in the laboratory and abnormal location point data based on the environmental monitoring data includes: obtaining identification strategies for all types of safety events; judging whether the environmental monitoring data hits at least one of the identification strategies for all types of safety events based on the environmental monitoring data and the identification strategies for all types of safety events; if the environmental monitoring data hits at least one of the identification strategies for all types of safety events, determining the type data of the safety event type corresponding to the hit identification strategy as the type data of the safety event occurring in the laboratory, and obtaining the location data of a monitor that outputs the abnormal environmental monitoring data; and obtaining the abnormal location point data of the safety events occurring in the laboratory based on the location data of the monitor that outputs the abnormal environmental monitoring data.

[0150] During specific implementation, when the laboratory safety event locator 103 obtains the type data of the safety event that occurred in the laboratory and the abnormal location point data according to the environmental monitoring data, it is judged according to the identification strategy of the safety event type, specifically judging whether the environmental monitoring data hits at least one of the identification strategies of all safety event types. It should be noted that the safety event type can specifically be a fire event, a toxic and harmful gas leakage event, a flammable and explosive gas leakage event, and a high-temperature and high-pressure container out-of-control event. The environmental monitoring data corresponding to the fire event can be temperature data, humidity data, smoke data, high-temperature data, fireworks data, gas concentration data, etc.; the environmental monitoring data corresponding to the toxic and harmful gas leakage event and the flammable and explosive gas leakage event can be gas concentration data, etc.; the environmental monitoring data corresponding to the high-temperature and high-pressure container out-of-control event can be temperature data, high-temperature data, fireworks data, instrument pressure data, gas supply pressure data, gas supply flow data, etc.

[0151] When judging whether the environmental monitoring data hits at least one of the identification strategies of all security event types, for example, the environmental monitoring data is temperature data, fireworks data and gas concentration data, and the corresponding security event type is a fire event, the identification strategy for determining a fire in a laboratory environment is: the oxygen concentration in the laboratory environment is lower than 19.5 and the PM2.5 is greater than 300. If the environmental monitoring data hits the identification strategy of a fire event, the type data of the security event that occurred in the laboratory is a fire event. After determining the type of security event, the location data of the monitor that outputs the abnormal environmental monitoring data is obtained, and then the abnormal location point data of the security event that occurred in the laboratory is obtained based on the location data of the monitor that outputs the abnormal environmental monitoring data.

[0152] After the laboratory safety event locator 103 obtains the type data and abnormal location data of the safety event occurring in the laboratory according to the environmental monitoring data, the type data and abnormal location data of the safety event are sent to the display screen controller 104; the display screen controller 104 is used to generate safety evacuation instruction data based on the type data and abnormal location data of the safety event, and send the safety evacuation instruction data to the display screen 105. The display screen 105 is used to prompt the safety evacuation instruction data. It should be noted that the display screen controller 104 can be set separately or integrated in the display screen 105.

[0153] In an embodiment of the present application, generating safe evacuation instruction data based on the type data of the security event and the abnormal location point data includes: obtaining a safe evacuation strategy corresponding to the type data of the security event; obtaining safe location point data; generating safe evacuation route data based on the safe evacuation strategy corresponding to the type data of the security event, the abnormal location point data and the safe location point data; obtaining display screen identification data in the safe evacuation route represented by the safe evacuation route data; generating safe evacuation instruction data that needs to be prompted for each display screen in the safe evacuation route based on the safe evacuation route data; sending the safe evacuation instruction data to the display screen includes: sending corresponding safe evacuation instruction data to each display screen in the safe evacuation route based on the display screen identification data in the safe evacuation route.

[0154] When generating safe evacuation instruction data based on the type data of the security event and the abnormal location point data, specifically, first obtain the safe evacuation strategy corresponding to the type data of the security event. For example, the safe evacuation strategy corresponding to a fire event is: use the evacuation stairs instead of taking the elevator; cover your mouth and nose with a wet towel, handkerchief, etc.; keep your body close to the ground, bend over or crawl forward, etc. The safe evacuation strategy corresponding to a toxic and hazardous gas leakage event is: hold your breath as much as possible; cover your mouth and nose with a wet towel, handkerchief, etc., etc. Then obtain the safe location point data, and based on the safe evacuation strategy corresponding to the type data of the security event, the abnormal location point data, and the safe location point data, safe evacuation route data can be generated.

[0155] In specific implementation, it is also necessary to obtain the display screen identification data located in the safe evacuation route represented by the safe evacuation route data; based on the safe evacuation route data, generate the safe evacuation instruction data that each display screen located in the safe evacuation route needs to prompt. The sending of the safe evacuation instruction data to the display screen includes: based on the display screen identification data located in the safe evacuation route, sending the corresponding safe evacuation instruction data to each display screen located in the safe evacuation route. See Figure 3 and Figure 4 , Figure 3 : is a schematic diagram of a third application scenario of a laboratory safety evacuation indication system provided in the first embodiment of the present application, Figure 4 This is a schematic diagram of the fourth application scenario of a laboratory safety evacuation indication system provided by the first embodiment of the present application. A display screen is provided at the door of each laboratory, and each display screen has identification data. For example, the identification of the display screen at the door of Laboratory 1 is Display Screen 1, etc. The laboratory personnel are located in Laboratory 6, the location of the safety incident is Laboratory 1, and the type of safety incident is a fire incident. Figure 3The direction indicated by the middle arrow is the evacuation direction. Since each laboratory is located in a different position, the safety evacuation instruction data that needs to be prompted on each display screen is also different. Therefore, when sending the safety evacuation instruction data to the display screen, the corresponding safety evacuation instruction data is sent to each display screen located in the safety evacuation route according to the display screen identification data located in the safety evacuation route. The display screen 105 is used to prompt the safety evacuation instruction data. It should be noted that when the display screen 105 prompts the safety evacuation instruction data, it can use voice, different color lights and other methods to prompt. For example, the safety evacuation instruction data corresponding to the display screen 6 at the door of laboratory 6 can be a voice broadcast: Please use a wet towel to cover your mouth and nose, try to keep your body close to the ground, bend over or crawl forward, turn right when you go out, and turn left at the end of the road; the safety evacuation instruction data corresponding to the display screen at the door of laboratory 2 is: Please use a wet towel to cover your mouth and nose, try to keep your body close to the ground, bend over or crawl forward, turn left when you go out, and turn left at the end of the road. Please continue to see Figure 4 , Figure 4 The diagram is a schematic diagram of the interface of display screen 6. The upper right corner of display screen 6 shows the entire escape route, and the upper left corner shows the content of the voice broadcast: Please wet a towel, cover your mouth and nose, bend over and move forward. The bottom of the display screen shows the direction of personnel evacuation, such as turning right when leaving the door, and also prompts that there are protective equipment in laboratory 5, as well as the location information of the next display screen.

[0156] In an embodiment of the present application, the safety evacuation strategy corresponding to the type data of the security event includes environmental monitoring data that needs to be avoided in the safety evacuation route corresponding to the type data of the security event; the generation of safety evacuation route data based on the safety evacuation strategy corresponding to the type data of the security event, the abnormal location point data and the safety location point data includes: obtaining the environmental monitoring data that needs to be avoided in the safety evacuation route corresponding to the type data of the security event from the safety evacuation strategy corresponding to the type data of the security event; obtaining multiple candidate route data from the abnormal location point represented by the abnormal location point data to the safety location point represented by the safety location point data ; For any one of the multiple candidate route data, obtain the environmental monitoring data of the passing point in any one of the candidate route represented by the any one of the candidate route data; determine whether there is environmental monitoring data matching the environmental monitoring data that needs to be avoided in the environmental monitoring data of the passing point in any one of the candidate route; if there is no environmental monitoring data matching the environmental monitoring data that needs to be avoided in the environmental monitoring data of the passing point in any one of the candidate route, determine the any one of the candidate route data as the safe evacuation route data, otherwise, determine the any one of the candidate route data as the unsafe evacuation route data.

[0157] During specific implementation, the safe evacuation strategy also includes environmental monitoring data that needs to be avoided in the safe evacuation route corresponding to the type data of the safety event. For example, for a toxic and hazardous gas leakage event, when determining a safe evacuation route, toxic and hazardous gases also need to be avoided. After obtaining multiple candidate route data from the abnormal position point represented by the abnormal position point data to the safe position point represented by the safe position point data, it is necessary to further determine whether there is environmental monitoring data that needs to be avoided in the environmental monitoring data of the passing position points in any candidate route. If not, it proves that the evacuation route is safe. If so, the evacuation route is unsafe.

[0158] In an embodiment of the present application, obtaining the identification data of a display screen located in the safe evacuation route represented by the safe evacuation route data includes: obtaining the location data of all display screens in the geographical object where the laboratory is located; determining all display screens located in the safe evacuation route represented by the safe evacuation route data based on the safe evacuation route data and the location data of all display screens; and obtaining the identification data of each display screen located in the safe evacuation route represented by the safe evacuation route data.

[0159] In the specific implementation, when obtaining the display screen identification data, first obtain the location data of all display screens, please continue to refer to Figure 3 , Figure 3 In this example, we take one floor as an example. In practice, we can obtain the location data of the display screens in the entire experimental building, and then obtain all the display screens in the safe evacuation route, and then obtain the identification data of each display screen, for example, Figure 3 The identification data of each display screen in the line from laboratory 6 to the safety exit.

[0160] In an embodiment of the present application, generating safe evacuation indication data that needs to be prompted for each display screen located in the safe evacuation route based on the safe evacuation route data includes: generating a position relationship diagram of the display screens in the safe evacuation route based on the safe evacuation route data and the position data of each display screen located in the safe evacuation route represented by the safe evacuation route data; determining the neighbor safety display screens of each display screen located in the safe evacuation route except for the display screen located at the last position in the safe evacuation route based on the position relationship diagram of the display screens, and for any display screen located in the safe evacuation route, starting from the position of the any display screen, traveling along the safe evacuation route to the position of the next display screen, and taking the next display screen as the neighbor safety display screen of the any display screen; generating safe evacuation indication data that needs to be prompted for each display screen and is used to point to the position of the neighbor safety display screen based on the neighbor safety display screens of each display screen.

[0161] In specific implementation, when generating the safety evacuation indication data that needs to be prompted for each display screen located in the safety evacuation route based on the safety evacuation route data, first generate a position relationship diagram of the display screens in the safety evacuation route. Except for the display screen at the last position in the safety evacuation route, the next adjacent safety display screen of each display screen can be determined according to the position relationship diagram as the neighbor safety display screen. According to the neighbor safety display screens of each display screen, the safety evacuation indication data that needs to be prompted for each display screen and is used to point to the location of the neighbor safety display screen can be generated. For example, please continue to refer to Figure 4 The current position is at display screen 6 at the entrance of laboratory 6. The next display screen according to the safe evacuation route is display screen 5 at the entrance of laboratory 5. At this time, display screen 6 will prompt the indication data for pointing to display screen 5.

[0162] In an embodiment of the present application, the safety evacuation strategy corresponding to the type data of the safety event includes specified abnormal environment monitoring data that requires the behavior subject to perform protective actions and data of the protective actions that the behavior subject needs to perform for the specified abnormal environment monitoring data; the display screen controller is also used to send an abnormal environment data inquiry message to the laboratory safety event locator for inquiring whether there is abnormal environment monitoring data in the safe evacuation route, and the abnormal environment data inquiry message includes the passing location point data of the safe evacuation route; the laboratory safety event locator is also used to send a safe route environment data request message for requesting to obtain the environmental monitoring data in the safe evacuation route to the laboratory environment data collector, and the safe route environment data request message includes the passing location point data of the safe evacuation route; the laboratory environment data collector is also used to collect the environmental monitoring data of the passing location point represented by the passing location point data according to the passing location point data of the safe evacuation route, and send the environmental monitoring data of the passing location point to the laboratory safety event locator; the laboratory safety event locator is also used to determine the environmental monitoring data of the passing location point Whether there is abnormal environment monitoring data in the monitoring data, if it is determined that there is abnormal environment monitoring data in the environmental monitoring data of the passing location point, then sending the abnormal environment monitoring data of the passing location point to the display screen controller in response to the abnormal environment data inquiry message; generating safe evacuation indication data that needs to be prompted for each display screen located in the safe evacuation route according to the safe evacuation route data, including: judging whether there is designated abnormal environment monitoring data that requires the behavior subject to perform a protective action in the abnormal environment monitoring data of the passing location point; if there is designated abnormal environment monitoring data that requires the behavior subject to perform a protective action in the abnormal environment monitoring data of the passing location point, then determining a display screen whose distance from the passing location point with the designated abnormal environment monitoring data is within a preset distance range according to the position data of the passing location point with the designated abnormal environment monitoring data and the position data of each display screen located in the safe evacuation route, as a protective action prompting display screen; for the protective action prompting display screen, generating data of the protective action that the behavior subject needs to perform with respect to the designated abnormal environment monitoring data that needs to be prompted by the protective action prompting display screen.

[0163] It should be noted that the safe evacuation strategy also includes specified abnormal environmental monitoring data that requires the subject of the behavior to perform protective actions and data on the protective actions that the subject of the behavior needs to perform based on the specified abnormal environmental monitoring data. For example, in the case of a fire incident, the PM2.5 concentration in the environment is relatively high. When escaping along the safe evacuation route, it is also necessary to determine whether there is abnormal environmental monitoring data in the environmental monitoring data of the location points along the safe evacuation route, that is, whether the PM2.5 at the location points along the route is abnormal. If so, the laboratory safety event locator 103 will send the abnormal environmental monitoring data of the location points along the route to the display screen controller 103. When generating the safe evacuation instruction data that needs to be prompted for each display screen located in the safe evacuation route based on the safe evacuation route data, first determine whether the abnormal environment monitoring data of the route location points contain designated abnormal environment monitoring data that requires the subject to perform protective actions. If so, then based on the position data of the route location points where the designated abnormal environment monitoring data exists and the position data of each display screen located in the safe evacuation route, determine the display screen whose distance to the route location points where the designated abnormal environment monitoring data exists is within a preset distance range as the protective action prompting display screen. The protective action prompting display screen will prompt the subject with the data of the protective action that needs to be performed according to the designated abnormal environment monitoring data. For example, due to the high PM2.5 content in a fire incident, the protective action prompting display screen will prompt the protective data of "wetting a towel and covering your mouth and nose".

[0164] In an embodiment of the present application, the safety evacuation strategy corresponding to the type data of the security event also includes specified abnormal environmental monitoring data that requires the behavior subject to perform protective actions and data of the protective actions that the behavior subject needs to perform in response to the specified abnormal environmental monitoring data; the display screen controller is also used to: if the environmental monitoring data of the passing location points in all candidate routes represented by the multiple candidate route data contain environmental monitoring data that matches the environmental monitoring data that needs to be avoided, then for any candidate route, determine whether all environmental monitoring data that match the environmental monitoring data that needs to be avoided in any candidate route are the specified abnormal environmental monitoring data that requires the behavior subject to perform protective actions; if all environmental monitoring data that match the environmental monitoring data that needs to be avoided in any candidate route are the specified abnormal environmental monitoring data that requires the behavior subject to perform protective actions According to the designated abnormal environment monitoring data for performing protective actions, any one of the candidate route data is determined as the safe evacuation route data; according to the safe evacuation route data, safe evacuation indication data that needs to be prompted for each display screen located in the safe evacuation route is generated, including: obtaining the position data of the passing position points in the safe evacuation route where the designated abnormal environment monitoring data exists; according to the position data of the passing position points where the designated abnormal environment monitoring data exists and the position data of each display screen located in the safe evacuation route, determining the display screen whose distance to the passing position points where the designated abnormal environment monitoring data exists is within a preset distance range as the protective action indication display screen; for the protective action indication display screen, generating the data of the protective action that the behavior subject needs to be prompted by the protective action indication display screen for the designated abnormal environment monitoring data.

[0165] It should be noted that the safe evacuation strategy also includes designated abnormal environmental monitoring data that requires the subject of the behavior to perform protective actions and data on the protective actions that the subject of the behavior needs to perform in response to the designated abnormal environmental monitoring data. If the path location point data in all candidate routes contain environmental monitoring data that needs to be avoided, it is determined whether the environmental monitoring data that needs to be avoided all need to perform protective actions. If so, the candidate route data can be used as safe evacuation route data. Here, the main purpose is to reduce the hazards caused by abnormal environmental monitoring data through protective actions. When generating safe evacuation indication data that needs to be prompted for each display screen in the safe evacuation route based on the safe evacuation route data, the location data of the path location points where abnormal environmental monitoring data exists in the safe evacuation route can be first obtained. Based on the location data and the location data of each display screen in the safe evacuation route, a protective action indication display screen that can prompt a protective action is determined. The protective action indication display screen is used to prompt the subject of the behavior with data on the protective action that needs to be performed in response to the designated abnormal environmental monitoring data. For example, for fire events, please continue to refer to Figure 3and Figure 4 During the escape process, the laboratory 4 is a path point. At this time, the display screen 4 at the door of the laboratory 4 can prompt the protection data of "wetting the towel and covering the mouth and nose".

[0166] In an embodiment of the present application, the display screen controller is also used to: determine whether the data of the protective action that the subject needs to perform in response to the specified abnormal environment monitoring data includes the data of protective equipment required for the subject to perform the protective action; if the data of the protective action that the subject needs to perform in response to the specified abnormal environment monitoring data includes the data of protective equipment required for the subject to perform the protective action, then obtain the location data of the protective equipment required by the subject in the geographical object where the laboratory is located; based on the location data of the protective equipment required by the subject in the geographical object where the laboratory is located and the location data of each display screen located in the safe evacuation route, determine a display screen whose distance from the location of the protective equipment required by the subject is within a preset distance range as a protective equipment prompt display screen; and for the protective equipment prompt display screen, generate the location data of the location of the protective device that needs to be prompted by the protective equipment prompt display screen.

[0167] In specific implementation, the display screen controller 104 will also determine whether the data of the protective action that the subject needs to perform in response to the specified abnormal environment monitoring data includes the data of the protective equipment required for the subject to perform the protective action. For example, for toxic and harmful gas leakage events, a gas mask needs to be worn. If protective equipment is required, the location data of the laboratory where the protective equipment is located is obtained. Based on the location data of the protective equipment and the location data of each display screen in the safe evacuation route, a protective equipment prompt display screen within a preset distance range can be determined. The protective equipment prompt display screen prompts the location data of the location of the protective device. For example, for toxic and harmful gas leakage events, please continue to refer to Figure 3 or Figure 4 During the escape process, a gas mask is placed in the laboratory 5. At this time, the display screen 5 at the door of the laboratory 5 can prompt "there is anti-gas equipment here".

[0168] In an embodiment of the present application, the generation of safe evacuation indication data based on the type data of the security event and the abnormal location point data includes: determining the security event level corresponding to the security event based on the type data of the security event; obtaining a correspondence table between the security event level and the safe evacuation strategy; obtaining the security location point data; and generating the safe evacuation indication data based on the security location point data, the abnormal location point data, and the correspondence table. The generation of safe evacuation indication data based on the security location point data, the abnormal location point data, and the correspondence table includes: obtaining a safe evacuation strategy corresponding to the security event level based on the correspondence table; obtaining protective action data for instructing the behavior subject to perform the security event level based on the security evacuation strategy; obtaining evacuation route data for instructing the behavior subject to safely evacuate based on the security location point data and the abnormal location point data; and generating the safe evacuation indication data corresponding to the security event level based on the protective action data and the evacuation route data.

[0169] In specific implementation, the security event level corresponding to the security event can also be determined based on the type data of the security event. The method of determining the security event level corresponding to the security event based on the type data of the security event includes: obtaining environmental monitoring data corresponding to the type data of the security event based on the type data of the security event; obtaining a corresponding relationship table between the threshold range to which the environmental monitoring data belongs and the security event level; and determining the security event level corresponding to the security event based on the environmental monitoring data and the corresponding relationship table. For example, if the security event is a fire event, different levels of security events are determined based on the data range of temperature data, humidity data, gas data, and fireworks data corresponding to the fire event. Different levels of security events correspond to different safety evacuation strategies. According to the safety evacuation strategy, the protective action data corresponding to the security event level that the subject needs to execute can be obtained; the evacuation route data can be obtained based on the safety location point data and the abnormal location point data; and the safety evacuation indication data corresponding to the security event level is finally generated based on the protective action data and the evacuation route data.

[0170] In an embodiment of the present application, the generation of safe evacuation indication data based on the type data of the security event and the abnormal location point data includes: obtaining safe location point data; obtaining the location point data of the current location of the behavior subject as the behavior subject location point data; obtaining the position relationship data between the behavior subject location point data and the abnormal location point data and the safe location point data; if the position relationship data indicates that the position distance between the behavior subject location point data and the abnormal location point data is not within a preset safety distance threshold range, then inputting the type data of the security event and the position relationship data into a safe evacuation indication data generation model to obtain the safe evacuation indication data output by the safe evacuation indication data generation model. If the position relationship data indicates that the position distance between the position point data of the behavior subject and the abnormal position point data is within a preset safety distance threshold range, the type data of the security event, the position relationship data and the future time period data to be evaluated are input into the safety position prediction model to obtain the prediction result output by the safety position prediction model to indicate whether the behavior subject is in a safe position in the future time period; if the prediction result indicates that the behavior subject is not in a safe position in the future time period, the type data of the security event and the position relationship data are input into the safety evacuation indication data generation model to obtain the safety evacuation indication data output by the safety evacuation indication data generation model.

[0171] It should be noted that when generating safe evacuation instruction data based on the type data of the security event and the abnormal location point data, the position relationship data among the three can be obtained based on the safe location point data, the abnormal location point data and the location point data of the subject. If the position relationship data indicates that the current location of the subject is unsafe, then based on the type data of the security event and the position relationship data, the safe evacuation instruction data generation model is used to obtain the safe evacuation instruction data, so that the subject can escape in time according to the safe evacuation instruction data. If the position relationship data indicates that the current location of the subject is safe, then based on the type data of the security event, the position relationship data and the future time period data to be evaluated, the safe position prediction model is used to determine whether the subject is in a safe position in the future time period. If the subject is not in a safe position in the future time period, then based on the type data of the security event and the position relationship data, the safe evacuation instruction data generation model is used to obtain the safe evacuation instruction data, so that the subject can escape in advance according to the safe evacuation route.

[0172] Of course, when implementing it, you can also refer to Figure 5 , Figure 5It is a fifth application scenario schematic diagram of a laboratory safety evacuation indication system provided by the first embodiment of the present application. The laboratory safety evacuation indication system may include a multi-factor screening module 501 for security events, a dynamic positioning analysis module 502 for security events, and a sound and light evacuation indication module 503 for interactive display screen at the door. The multi-factor screening module 501 for security events includes a potential safety hazard intelligent analysis submodule 5011 and a security event analysis submodule. The multi-factor screening module 501 for security events is used to conduct false alarm investigation on potential safety hazards and security events to ensure the accuracy of security events. This is mainly because the false alarm rate of a single monitoring device alarm is relatively high, which increases the difficulty of daily management of the laboratory. Through the multi-factor screening module for security events, security events can be screened to reduce the false alarm rate.

[0173] The multi-factor screening module 501 for security events can dynamically locate and analyze the data transmitted by the positioning module 502 for security events, and through the video analysis algorithm and various front-end data analysis algorithms, it can detect potential safety hazards in advance, issue early warnings, and detect problems in time. For example, after an abnormally high temperature occurs in an electric furnace, the abnormal use of the electric furnace can be detected in advance by monitoring the power consumption data and the smoke value around the device, and an alarm can be issued in time. When a potential safety hazard has occurred, the type of security event can be determined by analyzing and comparing the security event rating library, so that timely intervention can be made and emergency evacuation can be triggered, and an alarm can be issued.

[0174] It should be noted that in addition to fire accidents, the laboratory will also have many safety accidents such as toxic and harmful gas leakage, flammable and explosive liquid and gas leakage, and high-temperature and high-pressure container loss of control, which require emergency evacuation. The dynamic positioning analysis module 502 of safety events also includes a fireworks multi-factor recognition algorithm submodule 5021, a toxic and harmful gas leakage multi-factor recognition algorithm submodule 5022, a flammable and explosive object leakage multi-factor recognition algorithm submodule 5023, and a high-temperature and high-pressure container loss of control abnormal multi-factor recognition algorithm submodule 5024. Through the fireworks multi-factor recognition algorithm, the toxic and harmful gas leakage, the flammable and explosive object leakage, the high-temperature and high-pressure container loss of control abnormal multi-factor recognition algorithm, the location and type of the safety event can be accurately confirmed. The leakage of toxic and harmful and flammable and explosive gases is a comprehensive statistical analysis of the laboratory's long-term gas usage data, pressure data, and gas concentration data in the air. When a leak occurs, it is compared and analyzed with the long-term data to locate the leak point and alarm and notify relevant personnel. In case of abnormal loss of control of high-temperature and high-pressure containers or electric furnaces, the power consumption, internal pressure and other data of the experimental device can be monitored. At the same time, thermal imaging temperature measuring devices and smoke sensors can be installed near the experimental device. Through comprehensive analysis, when abnormal data occurs in the experimental device, the experimental device can be warned in time, and the interactive display screen at the door can provide dynamic evacuation instructions.

[0175] The interactive display screen sound and light evacuation indication module 503 at the door is used to prompt the safety evacuation indication data. The interactive display screens at the doors of each laboratory on each floor of the laboratory building can be used as face access control or display interfaces such as laboratory appointments, notifications, safety publicity videos, environmental monitoring, and safety warnings when no safety incidents occur. When a safety incident occurs and emergency evacuation is required, the display screen of each laboratory can automatically and dynamically switch to the emergency evacuation interface at the corresponding position on each door screen through the unified comprehensive judgment of the platform, and through the analysis of the point where the safety incident occurred, the display screens at the door of each laboratory will automatically avoid the accident site and give an example of the nearest emergency evacuation interface for the safety exit according to the point where the safety incident occurred, and guide the personnel through sound, light and arrow instructions.

[0176] In specific implementation, the display screen will provide different evacuation instructions for different types of security incidents. For example, when a fire incident occurs and emergency evacuation is required, the fire alarm will be sounded first, and the display screen at the door will automatically generate a dynamic evacuation map for the door of each laboratory through parameters such as the location of the laboratory where the fire occurred, the escape exit, and the number of people in each laboratory. Voice and line arrows will be used to guide personnel to move to the corresponding escape exits, and the display screen at the door can continuously play the fire escape guide. When a gas leak occurs and emergency evacuation is required, first, a gas leak occurs in the laboratory, and the laboratory location where the gas occurred, the type of gas leak, the amount of leakage, the location of the escape exit, the number of people in each laboratory, and other parameters will be used to automatically generate a dynamic evacuation map for the door of each laboratory. Voice and line arrows will be used to guide personnel to move to the corresponding escape exits, and the display screen at the door can continuously play the gas leak escape guide. When a chemical leak occurs and emergency evacuation is required, first of all, when a chemical leak occurs in the laboratory, the display screen at the door will automatically generate a dynamic evacuation map for the door of each laboratory through parameters such as the chemical leak point, leaked chemical type, leak amount, escape exit location, and the current number of people in each laboratory. Voice and graphic arrows will be used to guide people to move to the corresponding escape exits. At the same time, the display screen at the door can continuously play relevant chemical leak escape guides.
