[0019] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0020] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise", "include", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0021] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification, and should not be interpreted in an idealized or overly rigid manner.

[0022] When using expressions such as "at least one of A, B, and C, etc.", they should generally be interpreted according to the meaning of the expression commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0023] The fire safety engineering construction industry is one of the industries that is deeply integrated with cutting-edge technology. In recent years, with the rapid development of information technology and artificial intelligence technology, smart fire protection has been promoted and applied in civil buildings. At the same time, the data of some systems in the pipeline corridor has gradually been connected to the comprehensive pipeline corridor monitoring platform to realize the linkage between fire protection and monitoring.

[0024] The mainframes of each subsystem of traditional fire protection will print paper samples and use paper inspection records, which can easily lead to file stacking, information blockage, inadequate fire inspections, and untrue inspection records. Smart fire protection can store relevant data by building a database. The traditional automated fire protection system contains a large number of fire protection or related systems. These systems are independently set up and perform their respective duties. Each system only meets the monitoring requirements of its own system, but there is almost no information exchange between systems, thus forming a "information island". The data acquisition device can connect the data information collected by each fire protection or fire protection related system to the smart fire protection system, where the data information includes the operating status of each fire protection system, the status of the detector, the status of the sensor, the operation and linkage status of the fire protection equipment, the electronic tag, the video image and other information. Realize the unified management of information and realize further information processing and application. The data transmission of traditional fire protection to the mainframes of each system is terminated, and the alarm information and location can only be visualized through the CRT device. Each host mainly triggers the alarm linkage and records the alarm information. Traditional firefighting mainly relies on passive fire extinguishing. After a fire occurs, the detector triggers the alarm information to complete a series of linkage actions. In addition, in the harsh environment of the pipe gallery, the traditional independent smoke and temperature sensors have a high failure rate, a short service life, and low triggering accuracy. When an independent alarm sounds an alarm, if there are no people at the fire scene or the people indoors are unable to move, the alarm will not be discovered in time and cannot achieve the real alarm effect.

[0025] This disclosure combines the special structure, environmental factors, required fire-related systems, and working conditions of underground utility corridors to design a smart fire protection system suitable for utility corridors. This system uses distributed optical fiber linear temperature-sensing fire detectors and distributed image fire detectors in the corridor section to build a fire automatic alarm system that can transmit more information. At the same time, the fire warning system and other linkage systems are collected on the platform through the collector, which enhances the efficiency and safety of traditional fire protection in terms of fire prevention, fire location, linkage, and coordination.

[0026] First, the technical terms involved in this disclosure are explained as follows:

[0027] Underground utility corridor: Underground utility corridor is a public tunnel built underground in the city for laying municipal pipelines such as electricity, communications, radio and television, and water supply. Underground utility corridor can effectively prevent the "zipper road" phenomenon, so that technicians do not need to repeatedly dig the road surface, and can repair, maintain, expand and transform various pipelines in the utility corridor; at the same time, it greatly reduces the time for pipeline repair.

[0028] Underground utility corridor monitoring system: The underground utility corridor monitoring system is mainly used for real-time monitoring of the underground utility corridor environment, equipment, video and other information. It mainly includes: environmental monitoring subsystem, video monitoring subsystem, network monitoring subsystem, automatic fire alarm system, electrical fire monitoring system, etc. It provides management personnel with real-time information on the underground utility corridor by collecting real-time data from each subsystem.

[0029] Smart firefighting: Smart firefighting is an advanced solution. Compared with traditional firefighting, it focuses on breaking through information islands between systems, improving perception and early warning capabilities, and emergency command intelligence capabilities. Fire risks and impacts can be minimized through earlier detection and faster processing. The firefighting systems installed in the tunnel include automatic fire alarm systems, fire emergency lighting and evacuation indication systems, fire equipment power supply monitoring systems, combustible gas detection and alarm systems, electrical fire monitoring systems, fire door monitoring systems, gas fire extinguishing (ultra-fine dry powder fire extinguishing) systems, fire power supply monitoring systems, video monitoring systems, and other firefighting and firefighting-related systems.

[0030] Automatic fire alarm system: The automatic fire alarm system is composed of a trigger device, a fire alarm device, a linkage output device and other auxiliary function devices. It can convert physical quantities such as smoke, heat, and flames generated by combustion into electrical signals through fire detectors at the early stage of a fire and transmit them to the fire alarm controller. In the present disclosure, the fire alarm detection module realizes the alarm of the fire protection system by detecting smoke, heat, etc.

[0031] Electrical fire monitoring system: A system that can send out alarm signals, control signals and indicate the alarm location when the detected parameters in the protected line exceed the alarm setting value. It consists of electrical fire monitoring equipment (optional) and electrical fire monitoring detectors.

[0032] Fire power supply monitoring system: Fire equipment power supply monitoring system refers to a system that monitors, controls and manages the power supply of fire equipment in real time, aiming to ensure that the fire equipment can be started and operated in a timely and effective manner in an emergency. In this disclosure, the fire power supply is monitored by the voltage / current signal sensor of the fire equipment power supply.

Use distributed image fire detectors as the second trigger source, and at the same time transmit optical information, thermal imaging information, and alarm information to the upper platform through the monitoring host.

[0035] Through the embodiments of the present disclosure, by collecting electrical data (such as residual current, cable temperature, etc.), the state of electrical equipment can be monitored in real time to prevent the occurrence of electrical fires; by collecting alarm data (such as alarm information, fire door monitoring information, etc.), fire events can be responded to quickly; by obtaining image data and temperature data through distributed image fire detectors and distributed optical fiber linear temperature-sensing fire detectors, the fire scene situation can be displayed intuitively. The accuracy and comprehensiveness of fire monitoring are improved, and the fire extinguishing and evacuation effects are enhanced.

[0036] Based on the above embodiments, the data fire warning detection module includes at least one of a combined electrical fire detector, a front-end residual current detection probe, a cable temperature detection probe, a box temperature detection probe, and a voltage / current signal sensor of a fire-fighting equipment power supply.

[0037] In this embodiment, the voltage / current signal sensor of the fire power supply monitoring system is used to detect the voltage and current of the line.

It should be noted that the distributed optical fiber linear temperature-sensitive fire detectors and distributed image fire detectors are only used here to upload alarm information of abnormalities.

[0041] In this embodiment, the smoke detector is arranged with a radius of 4.4m; the temperature detector is arranged with a radius of 6.7m; the linear temperature fire detector arranged under the ceiling should be 0.1m away from the ceiling. The protection radius of the detector should meet the protection radius requirements of the point temperature fire detector; the distance from the detector to the wall should be 1m to 1.5m.

[0042] Through the embodiments of the present disclosure, more than one detection device is actually arranged. When the scale of the fire reaches a certain extent, as long as there are two detection signals, the alarm system will be triggered; at the same time, the alarm host will display the alarm information of the front-end equipment, which requires timely maintenance by the operation and maintenance personnel. At the same time, the pipe gallery and the tunnel are similar linear structures, using linear cable-type temperature detectors and image fire detectors (which can be understood as cameras); the equipment layer and the comprehensive well layer are similar to the structure of a three- or four-story bungalow, with small rooms inside, and are more suitable for point detectors with a circular detection range (smoke and temperature sensors). Through the alarm detection equipment on the equipment layer and the comprehensive well layer, comprehensive monitoring of fires can be achieved, the coverage and response speed of fire alarms can be improved, and it can be ensured that alarms can be issued in time when a fire occurs to ensure personnel safety.

[0043] On the basis of the above embodiments, the transmission layer includes a fire warning host, a fire alarm host, a distributed optical fiber linear temperature sensing fire detector host, a distributed image fire detector monitoring host and a remote transmission module; the fire warning host is used to receive the electrical data of the fire warning detection module and forward the electrical data to the platform layer; the fire alarm host is used to receive the alarm data of the fire alarm detection module and forward the alarm data to the platform layer; the distributed optical fiber linear temperature sensing fire detector host is used to receive the temperature data obtained by the distributed optical fiber linear temperature sensing fire detector and forward the temperature data to the platform layer; the distributed image fire detector monitoring host is used to receive the image data obtained by the distributed image fire detector and forward the image data to the platform layer; the remote transmission module is used to communicate between the host and the platform layer.

[0047] In this embodiment, the data storage module uniformly stores the fire collection data; the application function module divides the application into different function modules according to the functional requirements.

[0048] Through the embodiments of the present disclosure, the operation and maintenance personnel in the traditional fire protection system usually do not continue to pay attention to the fire control room, and the processing of fire alarm information is not timely enough. At the same time, the maintenance personnel of the pipe corridor sometimes still need to rely on fire protection professionals to handle various alarm information. The host of each subsystem of the traditional fire protection will print paper samples and use paper inspection records. The traditional fire protection system of the integrated pipe corridor contains a large number of fire protection or related systems, and there is almost no information exchange between these systems, thus forming a "information island". The data storage module of the present disclosure stores a large amount of electrical data, alarm data, etc. from various information sources, provides data support for fire analysis and early warning, and realizes long-term storage and rapid retrieval of data; through the application function module, multi-source information is integrated and applied to improve the efficiency of alarm processing.

[0049] Based on the above embodiments, Figure 3 The schematic diagram of the functional modules according to the embodiment of the present disclosure is schematically shown. The application function module includes a monitoring submodule, a linkage submodule, a maintenance submodule and an analysis submodule; the monitoring submodule is used to perform abnormal monitoring of the data of the data storage module; the linkage submodule is used to respond to the occurrence of an alarm and provide an evacuation and fire fighting plan based on the alarm data, temperature data and image data; the maintenance submodule is used to store the operation and maintenance plan and communicate with the remote management platform so that the remote management platform can supervise and guide the operation and maintenance; the analysis submodule is used to analyze the data of the data storage module; wherein the operation and maintenance plan includes at least one of the analysis list or legend of the operation and maintenance personnel information, the emergency plan, the rescue map and the alarm data; the rescue map includes at least one of the public fire fighting facilities and the rescue conditions around the tunnel.

[0050] Through the embodiments of the present invention, the application functions are divided into four sub-modules, and full use is made of fire protection and fire-related data such as cable temperature, box temperature, residual current, three-phase voltage and current, real-time temperature information, temperature sensing point distance information, visible light images, thermal imaging images, and fire door status information, fire damper status information, fan status information, and electric control manhole cover status information. It can realize fire electrical safety prevention, real-time monitoring, fire situation analysis, linkage confirmation of each subsystem, emergency plan, remote management, integrated display of data, and other functions to improve on-site operation and maintenance capabilities.

[0052] In this embodiment, for a pipe gallery with a large span, it is usually necessary to set up multiple fire alarm control extensions along the pipe gallery to achieve detection coverage, but the extensions are generally set up in equipment rooms or integrated wells without supervision. At the same time, the fire alarm control host will only display the alarm information of the extension, lacking overall information summary and visual display. Through the visual display of smart fire protection, the information of each extension and the devices mounted under each extension can be summarized, and the degree of abnormality of the overall system of each partition can be analyzed.

[0053] In this embodiment, the main fire control room of the integrated pipe corridor is usually located in the monitoring center, but due to the limitation of the specification, the fire control room will be set up in a separate room. The operation and maintenance personnel usually control the situation in the corridor through the integrated pipe corridor monitoring platform, and do not focus on the fire control room. The control of the subsystems of the overall fire protection will be relatively lagging, and the processing of alarm information will not be timely. Through the infrastructure of the smart fire protection Internet of Things, the relevant information of each fire protection subsystem can be integrated into the integrated pipe corridor monitoring platform, and the operation and maintenance personnel can pay attention to the fire protection related information in a timely manner. Abnormal and alarm information can guide the operation and maintenance personnel through pop-up windows or prompts.

[0054] In this embodiment, the monitoring module is used at least for: (1) real-time display of analog data: including real-time residual current, cable temperature, box temperature of non-fire protection circuits of each system, voltage, current value of fire protection circuits, real-time temperature of temperature-sensing optical fiber, and temperature distance of temperature-sensing points; real-time alarm information of each system, including information such as faulty equipment (module or equipment), circuit, address code, time, and location; (2) equipment monitoring: including the number of controller devices, the number of connected transmission devices, the number of online transmission devices, the number of faulty equipment, and the number of alarm devices; a list of all equipment and a search function; (3) abnormal data monitoring: including the number of faults, alarms, linkages, and feedbacks of each subsystem on the day. The number of alarms processed, shielded, silenced, fault reports, and repairs on the day; (4) display of drawing point information, which is essentially the same as the CRT graphical interface and is integrated into the platform for easy operation and linkage.
