Abstract
The utility model provides an automatic detection recorder of flame for building material incombustibility test device, includes flame detector, infrared camera, video transmission line, video storage and data processor and flame alarm device, flame detector and infrared camera are installed and are arranged in the central point that is arranged in burning sample perpendicular directly over mirror in being used for building material incombustibility test device test stove and put, flame detector and flame alarm device circuit connection, the infrared camera is connected with video storage and data processor with video transmission line. When the infrared camera and the flame detector detect that continuous flame is generated on the surface of the sample, the flame detector immediately sends out an alarm prompt, and the infrared camera automatically captures a flame video and automatically records flame time. The device has the advantages of simple structure, high safety, high automation degree, recording of flame video images of the sample in the whole process, display of test results, reduction of labor intensity of testers, optimization of working environment and improvement of working efficiency.
Description
Technical Field
The utility model relates to a building material incombustibility test device, in particular to an automatic flame detection and recording device used in the building material incombustibility test device.
Background
The test method of building material incombustibility is the main test method for testing incombustibility of main components of building products. One of the criteria of the test method is the sum of the times during which a flame lasting more than 5s is produced on the visible surface of the test specimen. Currently, the laboratory test method of the project is a visual method, namely once a sample is put into a test furnace of a building material incombustibility test device, a tester immediately and constantly watches a mirror above the test furnace, and after the continuous flame is observed and generated, the total flame time generated on the visible surface of the sample is recorded by a stopwatch. In actual detection, the flame occurrence time of various samples is different from 0-600s, the flame duration can reach 800 seconds at the longest, and therefore, if the project works under the visual fatigue of testers, the error is large, the labor intensity is high, only one device can be monitored, and the working efficiency is low.
Disclosure of Invention
Problem to prior art existence, the utility model discloses on original building material incombustibility test device basis that is arranged in, provide one kind and be arranged in building material incombustibility test device flame automatic detection recorder, easy and simple to handle, the result is accurate.
The technical scheme is that the automatic flame detection and recording device for the building material incombustibility test device comprises a flame detector, an infrared camera, a video transmission line, a video storage and data processor and a flame alarm device, and is characterized in that: the flame detector and the infrared camera are arranged in the center of a mirror which is arranged right above a combustion sample and in a test furnace of the building material incombustibility test device, the flame detector is connected with a flame alarm device circuit, and the infrared camera is connected with a video storage and data processor through a video transmission line.
The utility model discloses the technological effect is, whole record sample flame video image to carry out the test result at display terminal and show, reduced testing personnel's intensity of labour, optimized operational environment, improved work efficiency.
Drawings
Fig. 1 is a schematic connection diagram of the present invention.
Detailed Description
As shown in figure 1, the automatic flame detection and recording device for the building material incombustibility test device comprises a flame detector 1, an infrared camera 2, a video transmission line 3, a video storage and data processor 4 and a flame alarm device 5, wherein the flame detector 1 and the infrared camera 2 are installed in the center position of a mirror which is 1m above a test sample in the test furnace of the building material incombustibility test device, the flame detector 1 is in circuit connection with the flame alarm device 5, and the infrared camera 2 is connected with the data processor 4 through the video transmission line 3 and the video storage.
Working procedure
Installing a flame detector 1 and an infrared camera 2 in the center of a mirror which is 1m above a test sample and is used in a test furnace of a building material incombustibility test device, opening a human-computer operation interface terminal of a video storage and data processor 4, starting the flame detector 1 and the infrared camera 2, when flame appears on the test sample, triggering the infrared camera 2 while alarming by the flame detector 1, recording a flame video image of the test sample in the whole process, transmitting the flame video image to a video storage and recording device of the video storage and data processor 4, transmitting the flame video image to the video processor of the video storage and data processor 4 through a video transmission line 3, analyzing the flame duration, and displaying the test result on a display terminal.
Principle of operation
After the flame detector 1 catches a flame signal on the surface of a sample, an alarm prompt is sent immediately, simultaneously, the infrared camera 2 automatically catches a sample combustion flame video and automatically records the flame combustion flame video on the storage device, meanwhile, the sum of flame time and the whole test video can be transmitted to the video storage and data processor 4 in real time, and the test result is displayed, the test video is recorded, and the video can be inquired and played back to be displayed and output in a centralized mode through the terminal.
