[0024] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0025] Embodiment: This embodiment provides a comprehensive joint debugging management platform for subway FAS. The comprehensive joint debugging management platform for subway FAS includes two levels of management: a central monitoring and management level in the control center and multiple station monitoring and management levels.

[0026] The central monitoring and management level in the control center includes a main control module in the control center, a communication module in the control center, and a historical server. The communication module in the control center and the historical server are electrically connected to the main control module in the control center. The communication module in the control center is used for communication with multiple station monitoring and management levels. The historical server is used for archiving historical data of fire events. The main control module in the control center is used for receiving fire disaster information from multiple station monitoring and management levels, monitoring and managing the station monitoring and management levels, daily supervising the fire protection facilities of the station monitoring and management levels, and controlling the station monitoring and management levels in the jurisdiction area through the central monitoring and management level in the control center in a linkage manner.

[0027] The station monitoring and management level includes a station control module, a station communication module, a station monitoring module, and a station fire prevention control module. The station communication module, the station monitoring module, and the station fire prevention control module are electrically connected to the station control module. The station communication module is used for communication with the central monitoring and management level in the control center. The station monitoring module is used for monitoring fire disasters within the jurisdiction of the station. The station fire prevention control module controls fire disasters within the jurisdiction of the station. The station control module is used for collecting, summarizing, and recording fire information, and controlling the linkage operation of facilities within the jurisdiction of each station.

[0028] In this embodiment, the station monitoring module includes multiple fire detectors for the jurisdiction of the station. The fire detectors include photoelectric smoke detectors, air sampling smoke detection alarms, heat detectors, flame detectors, and combustible gas detectors. The station is divided into multiple fire prevention areas.

[0029] Specifically, photoelectric smoke detectors are used in places where there is a smoldering stage in the initial stage of a fire, a large amount of smoke is generated, and a small amount of heat is generated, with little or no fire radiation, such as various equipment and management rooms, passages, cable wells, stairwells, etc. in the station.

[0030] For places where the fire develops rapidly and can generate a large amount of heat, smoke and flame radiation, one or a combination of temperature detectors, inductive smoke detectors, and flame detectors are used. For example, large workshops such as vehicle depots (parking lots), operation and maintenance workshops, main substations, and control center halls, etc.;

[0031] For places where the fire develops rapidly, there is strong flame radiation and a small amount of smoke and heat, flame detectors are used. For example, the dangerous goods warehouse in the vehicle depot, etc.;

[0032] For places where combustible gases or combustible liquid vapors are used, produced or concentrated, combustible gas detectors are used. For example, the gas storage room in the canteen of the vehicle depot.

[0033] In this embodiment, the station monitoring module further includes a line-type fire detector. The line-type fire detector is composed of a linear temperature sensing cable, a microcomputer modulator, and a terminal box. The microcomputer modulator is electrically connected to the linear temperature sensing cable and the terminal box, and is used for fire detection in dangerous places such as cable tunnels, cable shafts, cable mezzanines, and cable trays. The linear temperature sensing cable is arranged in layers according to the cable tray, in a serpentine shape, and extends into the high-voltage cable shaft. The temperature sensing cable is used as a detection area every 150m - 200m and is directly connected to the terminal box to achieve automatic fire detection and alarm. The linear temperature sensing cable is a resetable analog temperature sensing cable, arranged in a sine wave shape or a straight line shape, to monitor whether the high-voltage cable exceeds the rated temperature and give an alarm in time. The alarm temperature of the linear temperature sensing cable can be set arbitrarily between 70°C and 140°C, and the alarm temperature error is not greater than ±10%. The linear temperature sensing cable is installed in a continuous connection wiring method without taps or branches, and is constructed strictly in accordance with the design requirements. If an intermediate joint is really needed, a special temperature sensing cable microcomputer modulator must be used. The microcomputer modulator is connected to a certain length of linear temperature sensing cable and the terminal box for use. The microcomputer modulator is provided with a signal processing circuit, including a signal acquisition circuit, a signal amplification and conversion circuit, a display circuit, an ambient temperature test circuit, etc. The microcomputer modulator continuously monitors the temperature sensing cable and the ambient temperature, and gives an alarm for the temperature increase and open circuit or short circuit caused by abnormal conditions.

[0034] In this embodiment, the station monitoring module further includes a tunnel fire detection system, which adopts one or a combination of Raman optical fiber detection technology and fiber Bragg grating detection technology;

[0035] Raman fiber optic technology is based on the principle of optical time domain reflectometer and the temperature effect of backward Raman scattering of optical fibers. It uses advanced OTDR technology for positioning and Raman scattering effect for temperature measurement. The signal measured by Raman fiber optic technology is the optical intensity signal of weak backward scattered light, and its optical intensity will be affected by factors such as attenuation of light-emitting components, fiber optic connectors, and bending, with poor stability. However, the signal transmission and temperature detection use the same optical cable, featuring the integration of sensing and transmission;

[0036] Fiber Bragg grating detection technology uses wavelength division multiplexing technology or a method of hybrid multiplexing with identical fiber Bragg gratings to cascade multiple fiber Bragg gratings in a single optical fiber for distributed measurement. The fiber Bragg grating temperature monitoring system mainly consists of three major parts: a sensing part, a transmission optical fiber, and a fiber Bragg grating demodulator. The signal detected by fiber Bragg grating technology is a wavelength signal, and it uses advanced digital measurement technology, which is not affected by factors such as light source fluctuations, connection losses, and random vibrations of optical cables;

[0037] The tunnel fire detection system is composed of devices such as tunnel fire detection hosts, temperature sensing optical fibers, or fiber Bragg gratings. The tunnel fire detection system will give early warnings and alarms for the temperature, fires, etc. in areas such as subway interval tunnels and cable channels.

[0038] Through the above technical solutions, the station monitoring module can be installed in a configured manner according to different regional ends of the subway, used to comprehensively monitor different areas of the subway, and can reliably monitor, give early warnings, and alarms for subway fires, so that the subway can operate normally and orderly, and eliminate fires in the budding state as much as possible, avoiding or reducing the losses of personnel and property in case of disasters.

[0039] In this embodiment, the station fire prevention control module includes on-site level devices. The on-site level devices include a gas fire extinguishing system, an AFC system, vertical elevators, a smoke exhaust and ventilation system, a fire pump, a sprinkler pump, a smoke exhaust and fire prevention valve, an electric smoke curtain, a fireproof rolling shutter door, etc. The gas fire extinguishing system and the smoke exhaust and ventilation system are arranged in each area under the jurisdiction of the station.

[0040] Specifically, when the station confirms the occurrence of a fire, the station control module at the station monitoring and management level controls the opening of all turnstiles of the AFC system throughout the station to facilitate the evacuation of personnel during a fire; controls all vertical elevators in the station to return to the first floor and remain in the door-open state, and passengers are prohibited from taking the vertical elevators; the gas fire extinguishing system uses the Inergen gas fire extinguishing system, which adopts a pipe network total flooding combined distribution method. The designed minimum fire extinguishing concentration is 37.5% (at the lowest design temperature), and the highest designed fire extinguishing concentration is 43% (at the highest design temperature). The gas is discharged to reach 95% of the minimum design concentration within 1 minute. The Inergen system can be started in ways such as back-pressure start, electric start, manual start, and emergency start; controls the fireproof rolling shutters installed on the evacuation passage to descend in place after the personnel evacuation is completed; controls the electric smoke curtain to descend in place immediately when a fire occurs as a fire partition; the smoke exhaust and ventilation system uses professional smoke exhaust fans, etc., to reduce the amount of smoke in the subway during a fire; conducts fire extinguishing treatment on the fire area through fire pumps and sprinkler pumps.

[0041] In this embodiment, the station fire prevention control module further includes on-site control equipment. The on-site control equipment includes fire hydrants, fire extinguishers, fire emergency lighting, evacuation signs, smoke masks, manual alarms, audible and visual alarms, broadcast announcements, etc. The fire hydrants, fire extinguishers, and smoke masks are used for on-site staff to conduct fire extinguishing treatment. Through fire emergency lighting, evacuation signs, audible and visual alarms, broadcast announcements, etc., it commands personnel evacuation, controls the spread and development of the fire.

[0042] In this embodiment, the fire start modes at the station monitoring and management level are divided into automatic start mode, manual start mode, and manual start by personnel;

[0043] The automatic start mode is that when any two fire detectors in the same fire prevention area both generate fire alarms, the station control module will consider that the possibility of a fire occurring on-site is relatively high and will automatically start the fire mode;

[0044] The manual start mode is that when any one fire detector in a fire prevention zone generates a fire alarm, the duty officer goes to the site to confirm the fire situation. When a fire actually occurs on-site, the duty officer can trigger any one of the manual alarms set on-site for confirmation. After the station control module receives the confirmation alarm, it will automatically start the fire mode;

[0045] The manual start by personnel mode is that when personnel discover a fire on-site, they use the communication tool on the manual alarm to notify the station control room of the station. The duty officer in the control room can directly manually start the fire mode through the station control module; through the use of the three fire start modes, it comprehensively covers the application scenarios during subway fires, can know the occurrence of a fire in the first time, and helps to quickly handle the fire.

[0046] Furthermore, when the fire mode is activated, the station fire control module cuts off the power supply to non-firefighting facilities in the relevant fire-related areas according to the power supply and distribution range, so as to prevent the fire from endangering non-firefighting facilities and causing electrical damage.

[0047] In this embodiment, the central monitoring management level of the control center also includes an information publishing server electrically connected to the main control module of the control center, and the information publishing server is used to publish fire location information or emergency event level identification to the passenger's mobile terminal, wherein the mobile terminal is connected to the information publishing server via the Internet. When a fire occurs, emergency evacuation information carrying evacuation direction indication identification is published through the information publishing server, which can further improve the efficiency of emergency induced evacuation and buy time for passengers to escape.

[0048] The subway FAS integrated joint management platform of the present invention, in the early stage of a fire, the system automatically receives physical quantity signals such as temperature changes and thermal radiation of smoke generated by fire combustion through fire triggering devices such as smoke, temperature and light fire detectors set on site, and converts them into electrical signals and inputs them into a station control module. The station control module can also manually notify the station control module of a fire alarm through a manual alarm button. The station control module processes and analyzes the input alarm signal. When it is determined to be a fire, it immediately sends out a fire alarm through fire alarm devices such as sound and light signals, and records and displays the time and location of the fire. At the same time, it links various smoke and exhaust systems, gas fire extinguishing systems, and smoke and fire prevention facilities such as fire doors and fire curtains to direct personnel to evacuate and control the spread and development of the fire. It can control and extinguish the fire to the maximum extent, buy time for passengers to escape, improve safety, and reduce property losses.

[0049] All technical features in this embodiment can be freely combined according to actual needs.

[0050] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
