Description

Technical Field

[0001] The present invention relates to the field of fire protection technology, and in particular to a building intelligent safety management and control method and system. Background Art

[0002] With the improvement of living standards, people's demand for a better life also increases. Smart buildings are one of the products. By adopting advanced computer control technology, management software and energy-saving system programs, the equipment in smart buildings can operate in an orderly and scientific manner, making people's lives more comfortable, convenient and energy-saving. The main contents of smart buildings include video surveillance systems, security alarm systems, building intercom systems, access control card systems and fire alarm systems.

[0003] Most fire alarm systems use smoke alarms to prevent fires. When the signal received by the smoke alarm reaches the alarm threshold, an alarm will be sounded. However, some problems may arise in actual use. For example, when a user is cooking indoors and a lot of smoke is produced by cooking, the smoke alarm will sound an alarm because the received smoke signal reaches the smoke concentration threshold, resulting in a false alarm. In the early stages of a fire when the smoke concentration is still very low, the smoke alarm will not sound an alarm because the received signal does not reach the smoke concentration threshold, resulting in missed alarms and missing the best time to extinguish the fire.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on the structures shown in these drawings without paying creative work.

[0016] Figure 1This is a flow chart of a building intelligent security management method in Example 1 of the present invention.

[0017] Figure 2 This is a structural diagram of a building intelligent security management and control system in Example 2 of the present invention. DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the present application clearer, some embodiments of the present application are further described in detail below in conjunction with the accompanying drawings and Examples. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. However, it will be appreciated by those skilled in the art that in the various embodiments of the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented.

[0019] Example 1: See Figure 1 Embodiment 1 of the present invention provides a building intelligent safety management and control method, including: S1, monitor the fire situation of the environment according to the obtained smoke concentration data C1; S1.1, obtain the smoke concentration data C1 of the detection area; S1.2, determine whether "C1>C0" is true, C0 is the smoke concentration threshold, if "C1>C0" is true, the smoke alarm sounds an alarm, and returns to S1.1; if "C1>C0" is not true, the smoke alarm stops the alarm, and returns to S1.1; It should be added that the most notable feature of the early stage of a fire is thick smoke. Because the burning material has not yet been completely burned, a large amount of smoke will be released. The smoke contains gaseous products produced by the pyrolysis or combustion of combustibles and a variety of tiny solid particles. As the smoke is released, the smoke concentration in the detection area will become larger and larger. Therefore, by detecting the smoke concentration to warn of the fire, people can detect the fire in time and take fire-fighting measures in the early stage of the fire.

[0020] S2, obtaining temperature data C2 and toxic gas content data C3; Acquiring the temperature data C2 and the toxic gas content data C3 specifically involves acquiring the temperature data C2 and the toxic gas content data C3 once every second preset time t02, and the second preset time t02 can be manually adjusted according to the actual use environment; if the smoke alarm is used in a place where fire is not monitored, the second preset time t02 can be set longer; if the smoke alarm is used in a place where fire is monitored, the second preset time t02 can be set shorter; the shorter the second preset time t02, the higher the sensitivity; It should be added that the time is obtained by a timer, and the first preset time length t01 is greater than the second preset time length t02.

[0021] S3, calculating the variance based on the first data set P1 and the second data set P2 and variance ; The variance is calculated by the following formula : ; The variance is calculated by the following formula : ; in For this The average value of temperature data, ; For this The average value of the toxic gas content data C3, ; It should be added that the temperature changes during the fire are divided into the initial growth stage, the full development stage and the attenuation stage. The temperature in each stage changes differently over time, and the variance can better reflect the change of the data. Therefore, the temperature variance is calculated by the acquired temperature data, and the temperature changes in the detection area are observed to assist in judging whether a fire has occurred in the detection area. The concentration of harmful gases in the early stage of the fire shows an upward trend, so the variance of the harmful gas concentration can also be calculated to assist in judging whether a fire has occurred in the detection area.

[0022] S4, based on smoke concentration data C1, temperature data C2, toxic gas content data C3, variance and variance Adjust the smoke concentration threshold C0; Specifically include: T1. Judgment " "Is it established? is the preset temperature data variance, if " " is established, enter T2; if " "If not true, go to T9; T2. Judgement "Is it established? is the preset variance of toxic gas content, if " " is established, enter T3; if " "If not true, go to T9; T3, ; T4. Judgement "Is it true? If " " is established, then enter T5; if " "If not true, go to T9; T5. Judge "Is it true? If " " is established, then enter T6; if " "If not true, go to T9; T6. Judgement "Is it established? is the preset value, ,like" " is established, then enter T8; if " If not, go to T7; T7, assignment for , return to T4; T8. Determine whether "C1≥C0" is true. If "C1≥C0" is true, no operation is performed; if "C1≥C0" is not true, assign C0=C1-Cr, where Cr is the preset smoke concentration threshold adjustment value; T9. Determine whether "C1≥C0" is true. If "C1≥C0" is true, assign C0=C1+Cr; if "C1≥C0" is not true, no operation; It should be added that if a fire is detected in the detection area only by judging whether the variance of the temperature data and the toxic gas content data is greater than the preset temperature data variance and the preset toxic gas content variance, respectively, misjudgment may occur, because if someone passes by the smoke alarm with a burning object that is emitting thick smoke, the temperature data and the toxic gas content data will first increase and then decrease, and the detected temperature data and toxic gas content will also change, thereby being misjudged as a fire. Therefore, it is more reasonable to judge whether a fire has occurred in the detection area by judging whether the latest preset value temperature data and harmful gas content data show an upward trend; at the same time, when a fire is detected in the detection area, if the smoke alarm sounds an alarm, the smoke concentration threshold does not need to be adjusted, otherwise the smoke concentration threshold needs to be adjusted to avoid missed reports; and when the monitoring area is not in the early stage of a fire, if the smoke alarm sounds an alarm, the smoke concentration threshold needs to be adjusted to avoid false alarms, otherwise the smoke concentration threshold does not need to be adjusted.

[0023] S5, perform safety monitoring of the environment according to the acquired toxic gas content data C3; Determine whether "C3>C30" is true, C30 is the preset toxic gas content. If "C3>C30" is true, an alarm sounds; if "C3>C30" is not true, no operation is performed; It should be added that in addition to providing early warning of fires, smoke alarms can also sound the alarm when the level of toxic gases in the air is too high, to remind people to implement anti-toxic safety measures and avoid being in toxic and dangerous environments.

[0024] The initial stage of a fire is the best time to extinguish it, because the fire has not yet spread, and the heat, fire source and fuel supply are relatively small. At this time, as long as it can be discovered and measures are taken in time to prevent the spread of the fire, the fire can be quickly extinguished to avoid huge losses; if this opportunity is missed, the fire will spread rapidly and become fierce, causing huge losses to people's personal safety and property safety. Therefore, using smoke alarms to detect smoke concentration can promptly remind people to take fire extinguishing measures in the early stages of the fire; if the smoke alarm falsely alarms, it will affect people's judgment of the fire. If the smoke alarm misses a report, it is very detrimental to people's personal safety and property safety.

[0025] The present invention timely adjusts the smoke concentration threshold C0 by real-time monitoring the temperature data C2 and the toxic gas content data C3 of the detection area, thereby achieving the effect of adjusting the smoke concentration threshold C0 according to the environment and avoiding the problems of false alarm and missed alarm of the smoke alarm.

[0026] The present invention obtains toxic gas content data C3, and sounds an alarm when the toxic gas content data C3 exceeds a preset toxic gas content C30, reminding people to implement safety measures, thereby achieving the effect of reminding people when the toxic gas content data C3 is too high.

[0027] Example 2: See Figure 2 Embodiment 2 of the present invention provides a building intelligent safety management and control system, including: A data acquisition module is used to acquire smoke concentration data C1, temperature data C2 and toxic gas content data C3 of the detection area; A timing module, used for obtaining time, wherein the timing module comprises a timer, and the timer is installed in the smoke alarm; Monitoring module, used to monitor whether the smoke concentration threshold CO needs to be adjusted; The smoke concentration threshold adjustment module is used to adjust the smoke concentration threshold according to the smoke concentration data C1, temperature data C2, toxic gas content data C3, variance and variance Adjust the smoke concentration threshold CO; The first alarm module is used to sound an alarm when the smoke concentration data C1 exceeds the smoke concentration threshold C0.

[0028] A building intelligent safety management and control system also includes a second alarm module, which is used to sound an alarm when the toxic gas content data C3 exceeds the preset toxic gas content C30.
