Abstract

The invention provides a fire smoke alarm with storage function, the alarm includes a control unit, a storage unit, a thermal infrared imaging unit, a plurality of smoke sensors, a plurality of linear temperature sensors, a fire alarm unit, the The control unit obtains the thermal imaging image of the scene through the infrared imaging unit, and analyzes the temperature points in the calibration image. When it is judged that there is a fire point, the control unit activates the smoke sensor and the linear temperature sensor, and the measured smoke data and Fit the temperature data to the image data, and analyze and judge whether the temperature value difference between adjacent distances is less than the threshold value, so as to judge whether there is a fire on the scene, and save the image data, temperature and smoke data of the fire scene, which improves the accuracy of fire alarm , and can more intuitively judge and analyze the cause of the fire, as well as the data analysis of the fire.

Description

technical field

[0001] The fire smoke alarm of the present invention is suitable for the field of safety alarm, and in particular relates to the field of fire smoke alarm. Background technique

[0002] When most fires occur, a large amount of smoke will be released. Smoke particles are one of the important early features of fires, so smoke detection can detect fires earlier. Smoke and fire alarms are now widely used in aircraft cabins, entertainment venues, server rooms, substations and other places. At the same time, there will be a high-temperature combustion area at the fire scene, so different areas will have different temperature points on the scene, but for a relatively closed scene, the fire scene cannot be observed from the outside at the first time, and false alarms often occur And cause the situation that personnel retreat and firefighters run in vain due to false alarm situation.

[0003] At present, photoelectric smoke and fire detectors are used in buildings. ...

Examples

Embodiment Construction

[0027] The content of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as figure 1 As shown, a fire smoke alarm with storage function, the alarm includes a control unit, a storage unit, a thermal infrared imaging unit, a plurality of smoke sensors, a plurality of linear temperature sensors, and a fire alarm unit;

[0029] The control unit is electrically connected to the storage unit, the thermal infrared imaging unit, the smoke sensor, the infrared sensor and the ultraviolet sensor; the plurality of smoke sensors respectively measure the smoke concentration at their respective setting positions, and transmit the smoke data to the control unit unit;

[0030] Such as figure 2 As shown, the fire smoke alarm has a working mode: the thermal infrared imaging unit shoots a thermal infrared image in the setting environment through an infrared camera, and stores the thermal infrared...
