[0001] The present application relates to the technical field of intelligent control of fire fighting in closed space, and particularly relates to a closed space deflagration accident fire extinguishing and life guarantee comprehensive system and method. BACKGROUND

Although the oxygen concentration is controlled below the oxygen concentration required for fire, the occurrence of fire is avoided from the source, the initiative in the face of fire is improved, thereby the economic loss can be reduced, the device has simple structure, reliable performance and high safety; but its structure is relatively simple, and the automatic control ability is poor, resulting in low deflagration accident fire extinguishing efficiency.

[0004] Prior art two, application number: CN202210191298.3 discloses a mine closed space multi-parameter monitoring system, which comprises a closed robot brain, a closed space multi-parameter alarm and a network transmission device. The closed robot brain is connected to the closed space multi-parameter alarm through the network transmission device. The closed space multi-parameter alarm is arranged in the to-be-measured closed area in the coal mine underground, and automatic and continuous environmental parameter monitoring of the closed space in the coal mine underground is realized. The heavy task of personnel on-site inspection can be liberated, not only the errors and human negligence of artificial detection can be eliminated, but also the monitoring efficiency is greatly improved; the monitoring of the environmental parameters of the closed space can be realized in real time and continuously, and is not affected by the arrangement and frequency of the inspection personnel, and the real-time data is strong; although the intelligent monitoring is automatic and continuous, and the adverse effects of human, machine and environment on closed management caused by personnel on-site measurement are avoided, but there is lack of effective life guarantee measures when the deflagration accident occurs, resulting in poor monitoring effect.

[0005] The prior art three, application number: CN201910470233.0 discloses a closed space life support system, including a protective clothing, the protective clothing is located in the closed space, the protective clothing is connected with the protective clothing gas supply device and the protective clothing exhaust device through the flange on the closed space, and the closed space is also provided with an emergency breathing device, the emergency breathing device is connected with the protective clothing, gas enters the protective clothing through the protective clothing gas supply device, and then supplies gas for human respiration, at this time, the excess gas entering the head cover and the exhaled gas are discharged to the external environment through the protective clothing exhaust device, the protective clothing meets the isolation of the human body and the welding environment, and the full-closed effect is achieved. Although the emergency breathing device can be started when the main gas source or pipeline fails, personal safety and rescue time can be ensured, but only life support can be realized, the function is relatively single, fire extinguishing during the explosion accident cannot be realized at the same time, and the life support effect is poor.

[0006] The prior art one, the prior art two and the prior art three have the problems of single function, poor intelligent level of the fire extinguishing and guarantee system in the closed space, and poor ability of realizing fire extinguishing and life guarantee at the same time, so that the application provides a closed space explosion accident fire extinguishing and life guarantee comprehensive system and method, which realizes the purposes of fire extinguishing and life guarantee in the closed space by arranging the function modules of fire alarm and life guarantee.

A comprehensive method for extinguishing fires and providing life support in confined space deflagration accidents, executed by the integrated system for extinguishing fires and providing life support in confined space deflagration accidents as described in any one of claims 1-6, characterized in that, Includes the following steps: The system monitors whether a fire has occurred in a confined space and the extent of the fire. If a fire is detected, an alarm is issued and the fire location information is sent to the fire suppression and life support subsystem. Whether a fire has occurred is determined by monitoring temperature, smoke, and flame parameters. Based on the location information of the fire, determine the nature and extent of the fire and select the appropriate firefighting procedure, while monitoring the oxygen concentration in the confined space and providing life support equipment. Record and analyze data on fire incidents, including the time of the fire, the amount of extinguishing agent used, and the spread of the fire. Through data analysis, improve system performance and emergency response strategies. Through network connection, remote monitoring and control of the system can be achieved. Users can monitor the system's operating status and perform remote operation and control anytime and anywhere through mobile phones and computer terminals.

8. The integrated method for extinguishing fires and ensuring life support in confined space deflagration accidents as described in claim 7, characterized in that, The process of monitoring whether a fire has occurred in a confined space and the extent of the fire includes the following steps: Multiple temperature sensors, smoke detectors, and flame detectors are deployed in a confined space to establish real-time Internet of Things (IoT) communication with the fire extinguishing and life support subsystems; the ratio of temperature sensors to smoke detectors to flame detectors is 1:3:

2. It receives signals from each temperature sensor, smoke detector, and flame detector, and analyzes the signals of temperature, smoke, and flame parameters. Based on the analysis results of at least one of temperature, smoke, and flame by the parameter signal analysis module, a judgment is made as to whether there is a fire in the confined space, and the judgment result is sent to the fire extinguishing and life support subsystem.

9. The integrated method for extinguishing fires and ensuring life support in confined space deflagration accidents as described in claim 7, characterized in that, The process of determining the nature and extent of a fire and selecting the appropriate firefighting procedure includes the following steps: Based on the location information of the fire, the stored executable instructions are retrieved and executed. The judgment results of the fire monitoring and alarm subsystem are received through the information interface. The judgment results are used to indicate the nature and extent of the fire. The nature and extent of the fire are stored in multiple alternative applications. At least one target application is determined. The target application is used to execute a fire extinguishing procedure based on the nature and extent of the fire. The fire extinguishing procedure includes the selection of extinguishing agents and fire extinguishing equipment. The extinguishing agents selected are dry powder, foam, and carbon dioxide. The fire extinguishing equipment includes fire nozzles, fire extinguishers, and spray systems. It monitors the oxygen concentration in a confined space and controls it according to a set safety threshold. When the oxygen concentration exceeds the safe range, it automatically activates the ventilation equipment to expel the excess oxygen. At the same time, it provides life support equipment for personnel in an accident, including respirators, fireproof clothing, and emergency call devices.
