Abstract

The invention relates to the technical field of sensors, in particular to a hazard source identification and guide system for disaster sites. The system comprises a first cognition module, a second cognition module and a risk management module. The first cognitive module monitors smoke dust or burnt smell in the environment, and the second cognitive module monitors personnel distress sound and circuit discharge sound. The system provides visual route guidance far away from a high-concentration area for rescue workers through monitoring smoke dust and burnt smell, generates a route leading to a calling position and avoiding the high-concentration area when a calling sound is detected, and generates an electric shock risk prompt when a discharging sound is detected. The system can be used for disaster sites such as fire disaster and the like, solves the problems that rescue workers cannot effectively avoid toxic gas, find trapped people and avoid hidden electric spark dangers in a low-visibility environment, and provides dangerous source identification and path planning.

  7. 7. The system of claim 1, wherein the first cognitive module is configured to provide visual directions through monitoring of smoke, burnt odors, and wherein the visual directions can provide the firefighter with a location in a fire scene that is far from high concentration when the firefighter is aiming to enter a fire rescue, enabling the firefighter to avoid a hazard source.
  8. 8. The system of claim 1, wherein when the second cognitive module detects a person calling for help, the risk management module directs the direction in which the person calling for help propagates, and in combination with the concentration value and the position change of the odor factor monitored by the first cognitive module, generates a route with relatively low smoke or odor concentration to help firefighters quickly reach the calling for help location.
  9. 9. The system of claim 1, wherein the second cognitive module is configured to monitor discharge sounds in an environment in which the firefighter is located in real time, and wherein the second cognitive module generates the second cognitive authentication to provide a basis for the risk management module to determine other sources of danger in the environment when the firefighter receives the first cognitive authentication generated by the first cognitive module by the risk management module to generate a route travel indicating the firefighter to travel.
  10. 10. The system of claim 9, wherein the risk management module generates a risk cue for the discharge of the circuit based on the second cognitive discrimination to enable a firefighter to circumvent the risk in time to address the risk that the firefighter may not be able to perceive the discharge of the circuit at a safe distance along its travel path due to a low visual concentration.
  11. 11. The system according to any one of claims 1 to 10, wherein the system is integrated on a mobile terminal comprising a cell phone, tablet or host.
  12. 12. A hazard source identification and guide method for disaster sites is characterized by at least comprising the steps of utilizing a first cognitive module to monitor smoke dust or burnt smell in an environment, utilizing a second cognitive module to monitor personnel distress sound and circuit discharge sound in the environment in real time, utilizing a risk management module to provide visual route guidance for firefighters based on monitoring of the smoke dust or burnt smell so that the firefighters can avoid the hazard source, combining the monitoring result of the smoke dust or burnt smell when the personnel distress sound is detected, generating a route with relatively low smoke dust or smell concentration to help the firefighters to reach a distress position quickly, and generating a hazard prompt aiming at electric shock risks when the circuit discharge sound is detected.

Description

Dangerous source identification and guide system for disaster site The original basis of the divisional application is the patent application with the application number 202210527326.4, the application day 2022, the 5 th month 13 th day and the invention name of a sound gas composite detection system and method, which claims the priority of the patent application with the application number 2021113378117, and the priority day 2021, the 11 th month 11. Technical Field The invention relates to the technical field of sensors, in particular to a hazard source identification and guide system for disaster sites. Background Part of people with allergic allergies can generate transient immune response when inhaling specific allergens, and excessive histamine is generated in the body to generate allergic symptoms. Excessive secretion of histamine can cause itching pain or edema of the skin, leaving the body in a pain state which is not symptomatic of the disease. Such conditions typically occur by requiring the human body to be exposed to a particular allergen. Publication No. CN104894278A relates to a method for rapidly and efficiently screening and detecting food allergens. The screening method comprises the following steps of extracting DNA of a sample, carrying out PCR amplification detection on the DNA of the sample, screening 16 allergen components on a single reaction tube at one time based on the multi-channel property of a PCR instrument, and determining the allergen components through two rounds of PCR. The prior art mainly detects allergens in human bodies. Allergens which can be harmful to human bodies are avoided through subjective judgment of the human bodies. Many allergens belong to substances which occur frequently in the living environment, such as pollen, catkin, large particle dust. A method for monitoring allergen in environment comprises the steps of obtaining first allergen information of a user and sensitivity information of the first allergen information through a smart client, obtaining a first allergen database through environment-friendly monitoring equipment, obtaining index information of the allergen in the first allergen database according to the first allergen database, obtaining a weighted value of the user to the first allergen according to the sensitivity information and the index information, and determining a first safety distance of the user to the allergen in air according to the weighted value. Or an allergic rhinitis prediction method based on an incremental neural network model is disclosed in China patent with publication number of CN106384008A, and comprises the following steps of establishing an allergic rhinitis daily data database, training the neural network model, collecting daily life data, sending the daily life data to a server, storing the daily life data to a user daily data record table, extracting current day data from the user daily data record table to form an n-dimensional vector, normalizing the current day data to be input into an allergic rhinitis pathological neural network model for allergic rhinitis probability prediction, judging whether an allergic rhinitis probability value is larger than 0.5 by intelligent household allergic rhinitis nursing equipment, if the user judges that allergic rhinitis is obtained, the user goes to a hospital to check by himself, transmitting a check result back to the server by the intelligent household allergic rhinitis nursing equipment, judging whether the check result is correct by the server, executing an incremental algorithm when the check result is wrong, and dynamically correcting the neural network model. Because the living environment of the human body is complex, the probability conversion error for the human body to touch the allergen is extremely large only through the data summary of the daily environment. When the system judges that the medicine is lost, the wrong medicine use can cause harm to human bodies. Based on the above, the invention relates to a sound gas composite detection system, which can accompany a human body in the form of a mobile terminal and monitor the allergen in the environment of the human body, and corresponding protective measures suggestions are generated through detection results of different body amounts of the allergen. Furthermore, since the applicant has studied numerous documents and patents on the one hand, and since the applicant has made the present invention, the text is not to be limited to all details and matters of detail, but this is by no means the present invention does not feature these prior art features, but rather the present invention has features of all prior art, and the applicant has remained in the background art to which this invention pertains. Disclosure of Invention Aiming at the problems in the prior art, the invention provides a sound gas composite detection method. The method at least comprises stress response risk assessment, wherein the stress res
