Description

Technical Field

[0001] The invention belongs to the technical field of fire detection equipment, and in particular relates to an automatic detection device and a detection method for a point-type infrared flame detector. Background Art

[0002] Fire detection is required in large oil tank storage areas, petrochemical operation areas, chemical plants, refineries, gas stations and other places where open flames are prone to occur or where the spread of open flames may cause serious dangers. The instrument commonly used for fire detection on the market is the flame detector.

[0003] Flame detectors are also called photosensitive fire detectors, which are fire detectors that detect the light intensity of flame burning and the flickering frequency of flames. According to the light characteristics of flames, there are three types of flame detectors used: one is an ultraviolet detector that is sensitive to the shorter wavelength ultraviolet radiation in flames; the other is an infrared detector that is sensitive to the longer wavelength infrared radiation in flames; the third is an ultraviolet / infrared hybrid detector that detects both the shorter wavelength ultraviolet and the longer wavelength infrared in flames. In order to prevent false alarms, dual-band and triple-band infrared flame detectors are more commonly used in actual use.

[0004] According to the requirements of 6.1.1 of the national standard (GB15631-2008 special fire detectors), the factory inspection of point-type infrared flame detectors must include four tests: consistency test, orientation test, repeatability test, and low temperature (operation) test. For purchasers or project users, it is necessary to sample the flame detectors to be installed on site for the above routine inspections (except low temperature tests). For the above three tests, according to the method required in 5.2 of the national standard (GB15631-2008), the detectors must be repeatedly operated to obtain the response threshold ratio. However, the current flame detector detection devices on the market have a low degree of automation and require a lot of manual participation, such as manually moving the flame detector, manually turning on and off the chopper, and manually looking at the light card stopwatch. At the same time, in the orientation test, only the horizontal angle of the flame detector is measured, which is a trumpet-shaped angle in the actual on-site use environment, and cannot fully reproduce the actual environment on site, affecting the accuracy of the test. Summary of the invention

[0005] The present invention provides an automatic detection device and a detection method for a point-type infrared flame detector. One purpose is to provide a detection device and a detection method that can make up for the fact that the detection device in the prior art cannot simulate the actual on-site use conditions during the azimuth test and can only measure the horizontal angle but not the solid angle; the second purpose is to provide a detection device and a method with more accurate test results and more standardized test data and result records.

[0026] Step 2: Open the back cover of the infrared flame detector, connect the integrated cabinet to the infrared flame detector, and after ensuring that the connection is reliable, cover the back cover of the infrared flame detector; then, fix the infrared flame detector on the fixing bracket and keep the indicator light of the infrared flame detector horizontally set;

[0027] Step 3: Turn on the gas source mechanism;

[0028] Step 4: Ignition;

[0029] Step 5: After successful ignition, start the orientation test and repeatability test of the detector;

[0045] The specific process of ignition in step four is as follows: after pressing the start button on the integrated cabinet, the upper computer sends an ignition command to the first control panel through the flame detector automatic detection. After receiving the command, the first control panel starts the ignition device. After detecting the flame, the photosensitive sensor transmits a signal to the first control panel. The first control panel stops the ignition action of the ignition device and sends the ignition success information to the upper computer. The flame detector automatically detects that the upper computer records the ignition success time locally. If the upper computer does not receive the ignition success data after 5 minutes, it will issue an "abnormal fire source" warning and trigger the fault indicator light on the integrated cabinet.

[0049] Step 3: If T is greater than 28 seconds, control the horizontal motor to move the infrared flame detector closer to the light source, then turn on the regulator and restart the timing to see the change of T; if T is still greater than 29 seconds, continue to move the infrared flame detector closer to the light source, if T is less than 27 seconds, proceed to step 4, if T is within 28 seconds ± 1 second, proceed to step 5;
