Description

一种监视温度的装置和方法Device and method for monitoring temperature 技术领域Technical field
本发明总的来说涉及智慧消防领域，具体而言，涉及一种监视温度的装置。此外，本发明还涉及一种监视温度的方法。The invention generally relates to the field of intelligent fire protection, and in particular to a device for monitoring temperature. In addition, the invention also relates to a method for monitoring temperature.
背景技术Background technique
随着室内用电器的增加，火灾发生的频率越来越高。此外，随着全球气温的逐年升高，诸如森林或露天仓库之类的室外场所中也时常发生火灾。火灾一旦发生，通常会快速地发展和蔓延速，极易造成重大人身和财产损失。火灾的及早预警是降低火灾风险和损失的重要手段。With the increase of indoor electrical appliances, the frequency of fires is getting higher and higher. In addition, as global temperatures increase year by year, fires often occur in outdoor locations such as forests or open warehouses. Once a fire occurs, it usually develops and spreads quickly, and it is very easy to cause significant personal and property damage. Early warning of fire is an important means to reduce the risk and loss of fire.
当前火灾报警监控主要采用感温探测器、感烟探测器、火焰图像识别等技术来监视待监控场地。然而，这些监测技术均仅能在起火冒烟后报警，无法在起火冒烟前进行灾前预警。而起火冒烟后，火灾会迅速发展和蔓延，如果此时才报警，则将留给救援人员较少的时间来处置火情以及开展救援。此外，感温感烟探测器一般为单点监控，其监控范围较小，工程量大，很难对起火点进行有效定位，且不适用于室外场所。而火焰图形识别则受光环境影响严重，且有隐私保护要求的环境不宜使用。At present, fire alarm monitoring mainly uses temperature-sensing detectors, smoke detectors, flame image recognition and other technologies to monitor the site to be monitored. However, these monitoring technologies can only report to the police after a fire or smoke, and cannot provide pre-disaster warning before the fire or smoke. After the fire and smoke, the fire will quickly develop and spread. If the police is called at this time, the rescuers will be given less time to deal with the fire and carry out the rescue. In addition, the temperature and smoke detectors are generally single-point monitoring, which has a small monitoring range and a large amount of engineering. It is difficult to locate the fire point effectively, and it is not suitable for outdoor places. The flame pattern recognition is seriously affected by the light environment, and the environment with privacy protection requirements is not suitable for use.
目前需要一种能在早期识别火灾风险、更高效且适用面更广的温度监视手段。There is a need for a temperature monitoring method that can identify fire risks early, is more efficient, and has a wider range of applications.

本发明至少具有下列有益效果：(1)通过本发明，可以在火灾早起、即在起火冒烟前识别火灾风险，这是基于本发明人的如下洞察：火灾的发展过程为：发热升温、阴燃、冒烟起火、火苗蹿起、火势扩大蔓延、大火燃气形成火灾、***，也就是说，在起火冒烟之前，易燃物会有相当长一段时间的能量积累，在此阶段通过能量的蓄积，易燃物的温度会逐渐升高，如在此阶段既可监视其温度的变化，则可以提前预警避免灾情的发生。因此，如果能够在升温和阴燃阶段识别火灾风险，则能有效地避免火灾的形成，否则在冒烟起火后，留给救火人员的处置时间将会非常少，为此本发明通过分析由热像摄像头所检测的温度数据，可以确定温升速率和温度趋势，由此可有效地在火灾发展的最早期识别火灾风险，为人工处理赢取充足时间，大幅降低火灾发生概率；(2)本发明通过热成像摄像头采集温度数据，可对视野内的所有像素点独立地获取温度数值并做报警判断，由此可快速锁定升温区域，从而可有效地实现较大范围内的火灾监控，且安装工程量小、不受环境光条件影响，此外，热成像摄像头也不会侵犯用户隐私，因此本发明的应用范围较广。The present invention has at least the following beneficial effects: (1) Through the present invention, the fire risk can be identified before the fire rises early, that is, before the fire starts to smoke. This is based on the inventor's insight: the development process of the fire is: heating up, overcast Fire, smoke and fire, fire flames, fire spread and spread, and fire gas forms fire and explosion, that is to say, before the fire and smoke, combustibles will have a long period of energy accumulation, at this stage through the energy Accumulation, the temperature of flammables will gradually increase, if you can monitor the temperature changes at this stage, you can early warning to avoid the occurrence of disasters.

本发明所基于的思想是，不同的监测物品有各自的燃点，假定某类燃煤的着火点为190至270℃，但由于燃煤的自身的汽化以及环境因素的影响，煤堆内部会积聚热量以及汽化出可燃物，当内部积聚热量到达40℃时会加速汽化出的可燃物质产出，当汽化出来的可燃物质浓度达到一定值，且内部积聚的热量温度达到80摄氏度时，煤堆就会在内部阴燃，进而会逐渐扩大阴燃面积，同时随着阴燃的发生温度达到燃煤的着 火点时，火势将会迅速扩大最终导致灾情的发生。在上述这个场景中，可设定三个不同等级的监测报警阈值(40℃、80℃、190℃)，并实时监控煤堆的温度变化情况，当某一时刻的单个温度点达到报警阈值时就会触发对应等级的报警。同时，还可以根据不用物品的燃烧特点采用温升速率报警(例如报警阈值为20℃/min，当温升速率达到20℃/min时触发报警)，即根据多个时间点采集的温度来计算实际的温升速率。The idea underlying the present invention is that different monitored items have their own ignition points. It is assumed that the ignition point of a certain type of coal is 190 to 270°C. However, due to the gasification of the coal and the influence of environmental factors, heat will accumulate inside the coal pile And the combustibles vaporized, when the internal heat accumulation reaches 40 ℃, it will accelerate the output of vaporized combustible materials. When the concentration of vaporized combustible materials reaches a certain value, and the temperature of the internal heat accumulation reaches 80 degrees Celsius, the coal pile will The smoldering inside will gradually expand the smoldering area. At the same time, when the temperature of smoldering reaches the ignition point of coal combustion, the fire will expand rapidly and eventually lead to disasters. In this scenario, you can set three different levels of monitoring alarm thresholds (40℃, 80℃, 190℃), and monitor the temperature change of the coal pile in real time. When a single temperature point at a certain moment reaches the alarm threshold The corresponding level of alarm will be triggered. At the same time, you can also use the temperature rise rate alarm according to the combustion characteristics of unused items (for example, the alarm threshold is 20℃/min, and the alarm is triggered when the temperature rise rate reaches 20℃/min), that is, it is calculated according to the temperature collected at multiple time points The actual rate of temperature rise.
本发明具有如下特点：The invention has the following characteristics:
1)在升温阶段即可检测到温度的变化并进行预警，可及早发现火灾隐患；1) The temperature change can be detected and early warning can be detected during the heating stage, and the hidden fire hazard can be discovered early;
2)通过视频技术可进行大面积监控，安装工程量小；2) Large-area monitoring can be performed through video technology, and the amount of installation works is small;
3)对视野内的所有像素点独立地获取温度数值，并做报警判断。由此快速锁定升温区域；3) Obtain temperature values independently for all pixels in the field of view and make alarm judgments. This quickly locks the heating area;
4)红外热成像技术不受光线、烟雾等影响，区别于普通视频，特别适合有隐私保护要求的环境。4) Infrared thermal imaging technology is not affected by light, smoke, etc., and is different from ordinary video, especially suitable for environments with privacy protection requirements.
