Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the false alarm rate of fire alarms in the prior art is high, and the large-scale city-level remote monitoring of fire protection lacks technical support. A method for regional fire alarms is provided, which utilizes the correlation of multiple single-type fire detector signals Carry out fire alarms to reduce the false alarm rate and provide technical support for large-scale city-level fire remote monitoring systems

Embodiment 1

[0046] Keyword Explanation:

[0047] Field calculation: The general term for the fire prediction and judgment process for the detection signal.

[0048] Trigger Threshold: The minimum signal value calculated by the detector detection signal trigger field. (for analog detectors)

[0049] Alarm Threshold: The minimum signal value at which the detector detection signal triggers an alarm response. (for switch detectors)

[0050] Fire alarm threshold: The minimum probability value that is judged as a true fire alarm in the fire alarm judgment.

[0051] Building structure micro-elements: such as figure 1As shown, if the building is regarded as a structure composed of different functional spaces, then different functional spaces have certain specific layouts due to their specific functions, such as corridors and stairwells belonging to narrow and long connected structures, rooms and equipment rooms belonging to Closed or semi-closed chamber structure. The spread of fire smoke i...

Embodiment 2

[0110] Corresponding to Embodiment 1, this embodiment provides a regional fire alarm system, including the following steps:

[0111] System trigger module, calculating the trigger field of a single detector A in the building;

[0112] The positioning module locates the building structure micro-element where the single detector A is located, and identifies the adjacent detectors;

[0113] The building structure micro-element determination module selects the building structure micro-element signal parameter unit where the single detector A is located, so as to determine the fire alarm threshold parameter corresponding to the building structure micro-element; at the same time, the building structure micro-element signal parameter unit acquires the detection The detection signals of the detector and its adjacent detectors are processed to obtain signal characteristics;

[0114] Among them, the signal characteristic model is the same signal relationship value between the single dete...

Embodiment 3

[0167] like Image 6 As shown, corresponding to Embodiment 1 and Embodiment 2, this embodiment provides a safety cloud platform. The fire safety cloud platform is divided into a three-layer structure. The first layer is for social units, the second layer is for regional centers, and the third layer is for The layer is the total center.

[0168] level one

[0169] The first layer can be called the front-end perception layer. Taking the social unit as a whole, a fire alarm system is established to analyze and process the switch / analog signal of a single fire detector. When the signal reaches the trigger threshold / alarm threshold, the trigger field It can realize the joint application of edge computing and regional fire alarm model.

[0170] Second floor

[0171] The second-level regional center is mainly aimed at the city, and connects the signal of the fire alarm system to the regional center on a regional basis. The regional center stores the building BIM model of the acce...

Abstract

The present invention provides a regional fire alarm method, comprising: S01. Calculating the trigger field of a single detector A in a building; S02. Locating the micro-unit of the building structure where the single detector A is located, and identifying adjacent detectors; S03. Select the micro-signal parameter unit of the building structure where the single detector A is located, obtain the detection signals of the detector and its adjacent detectors, and obtain the signal characteristics after processing; S04. Input the signal characteristics into the fire alarm model, and determine Whether there is a fire; S05. According to the judgment, output a real alarm or a false alarm signal. For different building structure elements, the law of fire smoke spread is different, so the correlation of adjacent smoke signals is also different; the correlation of adjacent smoke signals caused by the law of fire smoke spread is used as the fire alarm Judging the standard, and then using the standard to carry out fire alarm, can greatly reduce the false alarm rate and improve the alarm efficiency.

Description

technical field [0001] The invention relates to the technical field of fire early warning, in particular to a fire safety monitoring method, system and cloud platform. Background technique [0002] The urban fire remote monitoring system is a combination of the most advanced contemporary fire alarm technology, information communication and network technology, computer control technology and multimedia display technology, through public (unit) telephone network, local area / wide area network, wireless GPRS / CDMA network, etc. It collects and monitors various alarm signals, fault signals and image information in real time, and transmits the above information to the equipment of the remote alarm detection center in a timely and reliable manner. In the center, the alarm information display, electronic map operation, data query and retrieval, remote audio and video transmission, emergency plan management, short message ordering and sending can be completed for networked units. Und...
