Therefore, the reliability of the operating status of fire detectors is crucial and directly related to whether fires can be discovered and effectively dealt with in a timely manner. Regularly testing the action of fire detectors to ensure that they can work normally at critical moments is an important part of ensuring fire safety.

[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

Unless otherwise specified, the above-mentioned directional descriptions can be flexibly set in the process of actual application under the condition that the relative positional relationship shown in the accompanying drawings is satisfied.

[0049] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 An embodiment of the present application provides a fire detector action test device, including a test seat 1 with a test area 11, on which a laser aligner 2 and a flame simulation radiation source 3 are provided. The laser aligner 2 is used to emit visible laser outward from the test area 11, and the flame simulation radiation source 3 is used to emit a radiation signal simulating the radiation characteristics of a flame outward from the test area 11.

[0051] The test seat 1 is used to install other components of the test device, and can be made of strong and durable materials, such as high-strength metal alloys or high-strength engineering plastics, to ensure the stability and durability of the test device. Exemplarily, the test seat 1 can be made of aluminum alloy to meet the requirements of light weight, long service life and high heat dissipation. A test area 11 is provided on one side of the test seat 1, and the test area 11 is used to face the fire detector to be tested during the test operation.

[0052] The laser aligner 2 is installed on the test socket 1, and is used to emit visible laser light from the test area 11 for alignment. Visible laser light refers to laser light that can be perceived by the human eye, such as laser light with a wavelength between 400-700nm. During the test operation, the laser aligner 2 emits laser light to the fire detector to be tested, which can clearly indicate the position of the fire detector to be tested, thereby assisting the operator to quickly and accurately direct the test area 11 of the test socket 1 toward and align the fire detector to be tested.

[0053] Since the human eye with normal vision is most sensitive to electromagnetic waves with a wavelength of about 555nm, which is in the green light region of the optical spectrum, the laser alignment tool 2 uses a 532nm laser pen to emit a green laser beam. Of course, in other embodiments, the laser alignment tool 2 can also use a laser pen that can emit a red, blue or blue-violet laser beam, as long as it can be observed by the human eye, and no specific limitation is made here.

[0054] The flame simulation radiation source 3 is installed on the test seat 1, and is used to emit radiation signals simulating the radiation characteristics of flames from the test area 11. These radiation signals are similar to the radiation signals generated by real flames in terms of wavelength, intensity, etc., so that the flame radiation characteristics in real fire scenes can be simulated without using open flames, providing a realistic test environment for the action test of fire detectors. During the test operation, the flame simulation radiation source 3 can stably emit radiation signals simulating the radiation characteristics of flames, and also avoids the problem of unstable test results caused by factors such as flame jitter and different sizes in traditional flame tests.

[0055] The present invention provides a method for testing the operation of a fire detector, comprising the following steps:

[0056] S1. Place the fire detector action test device provided in the above embodiment in the monitoring area of ​​the fire detector to be tested. Exemplarily, the distance between the fire detector action test device and the fire detector to be tested is no more than 20m, and the laser aligner 2 and the flame simulation radiation source 3 are powered by the power supply 9. The power supply 9 can be a mains or a battery.

[0057] S2, control the laser aligner 2 to emit visible laser light outward, and adjust the angle of the test seat 1 to align the visible laser light with the fire detector to be tested. This operation can ensure that the test area 11 is aligned with the fire detector to be tested, and ensure that the radiation signal emitted by the flame simulation radiation source 3 can be fully covered by the fire detector to be tested, so that the fire detector can receive the strongest trigger signal source.

[0058] S3, control the flame simulation radiation source 3 to emit a radiation signal simulating the flame radiation characteristics to trigger the fire detector to be tested. When the fire detector sends out an alarm signal, it indicates that the fire detector is in good operating condition; when the fire detector does not send out an alarm signal, it indicates that the fire detector is in abnormal operating condition and needs to be repaired or replaced.

[0059] The fire detector action test device and method provided in the embodiment of the present application are provided with a test socket 1 having a test area 11, and a laser aligner 2 and a flame simulation radiation source 3 are provided on the test socket 1. The flame simulation radiation source 3 can emit a radiation signal simulating the flame radiation characteristics from the test area 11, and the laser aligner 2 can emit a visible laser to the fire detector to be tested, so as to align the test area 11 with the fire detector to be tested, thereby ensuring that the radiation signal emitted from the test area 11 by the flame simulation radiation source 3 can accurately act on the sensing part of the fire detector to be tested, thereby realizing the action test of the fire detector.

[0060] Compared with the existing technology, the present application can simulate flame characteristic signals without using open flames, thereby realizing comprehensive, safe and reliable testing of fire detectors, solving the problem that traditional flame testing methods cannot be used in special places such as chemical workshops, oil depots, and hospital operating rooms due to the risk of causing fire or explosion.

[0061] Fire detectors are key equipment in the automatic fire alarm system. Depending on their working principles, they can include infrared flame detectors, ultraviolet flame detectors, and image-type flame detectors.

[0062] In some embodiments, see Figure 2 The flame simulation radiation source 3 includes at least one of an infrared radiation source 31, an ultraviolet radiation source 32 and a full-spectrum radiation source 33. The infrared radiation source 31 is used to emit an infrared radiation signal, which can trigger the alarm action of the infrared flame detector; the ultraviolet radiation source 32 is used to emit an ultraviolet radiation signal, which can trigger the alarm action of the ultraviolet flame detector; the full-spectrum radiation source 33 is used to emit a full-spectrum radiation signal, which can trigger the alarm action of the image-type flame detector.

[0063] The fire detector action test device provided in the embodiment of the present application, when the flame simulation radiation source 3 includes at least two of the infrared radiation source 31, the ultraviolet radiation source 32 and the full-spectrum radiation source 33, any one or more combinations of the infrared radiation source 31, the ultraviolet radiation source 32 and the full-spectrum radiation source 33 can be selected according to the test requirements. This flexibility enables the test device to simulate the triggering of multiple different types of fire detectors, thereby improving the versatility and practicality of the test device.

[0064] In some embodiments, the infrared radiation source 31 can be an infrared signal source capable of releasing a wavelength of 3-5 μm and a frequency of 2-20 Hz, which is used to trigger the alarm action of the infrared flame detector. The ultraviolet radiation source 32 can be an ultraviolet signal source capable of releasing a wavelength of 185-400 nm, which is used to trigger the alarm action of the ultraviolet flame detector.

[0065] In some embodiments, see Figure 2 The full spectrum radiation source 33 may include a halogen lamp 331 and a shielding mechanism 332 for intermittently shielding the halogen lamp 331; the halogen lamp 331, as an energy release source, can release light waves in the 0.35-3.5 μm band, covering the receiving range of most spectral bands based on the principle of image fire detection. Due to the high power characteristics of the halogen lamp 331 itself, it is unable to perform high-frequency on-off changes. Therefore, the shielding mechanism 332 is used to intermittently shield the halogen lamp 331 to modulate the radiation source of the halogen lamp 331 to achieve the purpose of simulating flame flickering, which is used to trigger the alarm action of the image-type flame detector.

[0066] For example, see Figure 5 The shielding mechanism 332 includes a motor 3321 and a swinging blade 3322 connected to the motor 3321, and the motor 3321 is used to drive the swinging blade 3322 to intermittently shield the halogen lamp 331. The motor 3321 is installed on the test seat 1, and the swinging blade 3322 is installed on the output shaft of the motor 3321. After starting the motor 3321, the motor 3321 drives the swinging blade 3322 to swing, and the swinging blade 3322 intermittently shields the halogen lamp 331; by controlling the swing amplitude and frequency of the swinging blade 3322, the radiation source of the halogen lamp 331 is modulated to achieve the purpose of simulating flame flickering, which is used to trigger the alarm action of the image-type flame detector.

[0067] In some embodiments, see Figure 1 , Figure 2 The test seat 1 is provided with a mounting cavity 12, the laser aligner 2 and the flame simulation radiation source 3 are arranged in the mounting cavity 12, the test area 11 is provided with a laser emitting hole 13 facing the emitting head of the laser aligner 2, and the test area 11 is also provided with a transparent window 14 facing the flame simulation radiation source 3. Exemplarily, the transparent window 14 can be made of glass, PVC board, etc.

[0068] By arranging the laser aligner 2 and the flame simulation radiation source 3 in the installation cavity 12, the laser aligner 2 and the flame simulation radiation source 3 can be effectively protected from external physical damage, the service life can be extended, and the durability of the test device can be improved. By setting the laser emission hole 13, the laser emitted by the laser aligner 2 can be emitted outward through the laser emission hole 13. By setting the transparent window 14, an output channel is provided for the radiation signal emitted by the flame simulation radiation source 3, so that the radiation signal can be output outward through the transparent window 14 of the test area 11, while reducing the interference of external environmental factors on the radiation signal, ensuring that the radiation signal can act on the fire detector clearly and stably.

[0069] Exemplarily, the test seat 1 is a rectangular test box, the inner cavity of the test box forms an installation cavity 12, and the front side wall of the test box forms a test area 11. The laser aligner 2, the infrared radiation source 31, the ultraviolet radiation source 32, the halogen lamp 331, the motor 3321 and the swinging fan blade 3322 are all installed in the installation cavity 12, the laser emission hole 13 passes through the front side wall of the test box, and the emission head of the laser aligner 2 is installed in the laser emission hole 13 so that the laser is emitted outward through the laser emission hole 13. Among them, the laser emitted by the laser aligner 2 can be perpendicular to the front side wall of the test box. The transparent window 14 may include one, and the radiation signals emitted by the infrared radiation source 31, the ultraviolet radiation source 32 and the halogen lamp 331 are simultaneously output outward from the transparent window 14. See. Figure 1The transparent window 14 may also include three transparent windows 14, which are an infrared transparent window 141, an ultraviolet transparent window 142 and a halogen lamp transparent window 143; the infrared transparent window 141 is directly opposite to the infrared radiation source 31, and the radiation signal emitted by the infrared radiation source 31 can be output outward through the infrared transparent window 141; the ultraviolet transparent window 142 is directly opposite to the ultraviolet radiation source 32, and the radiation signal emitted by the ultraviolet radiation source 32 can be output outward through the ultraviolet transparent window 142; the halogen lamp transparent window 143 is directly opposite to the halogen lamp 331, and the radiation signal emitted by the halogen lamp 331 can be output outward through the halogen lamp transparent window 143, wherein the swinging fan blade 3322 is arranged between the halogen lamp 331 and the halogen lamp transparent window 143, and the motor 3321 drives the swinging fan blade 3322 to swing back and forth, and then the swinging fan blade 3322 is used to intermittently block the halogen lamp 331.

[0070] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 The fire detector action test device provided in the embodiment of the present application also includes a power converter 4 and a control switch 5. The power converter 4 is connected to the laser aligner 2 and the flame simulation radiation source 3 respectively through the control switch 5.

[0071] Accordingly, a power converter 4 is provided to centrally manage and distribute a power source 9 such as a mains or a battery, so as to provide an adaptive working voltage and current for different types of flame simulation radiation sources 3 and laser alignment devices 2. A control switch 5 is provided to control the opening and closing of the laser alignment device 2 and the flame simulation radiation source 3.

[0072] For example, see Figure 1 , Figure 3 , Figure 6 The control switch 5 includes a main power switch 51, a laser aligner switch 52, an infrared radiation source switch 53, an ultraviolet radiation source switch 54, a full-spectrum radiation source intensity knob 55, and a full-spectrum radiation source frequency knob 56; the power converter 4 is connected to the power supply 9, and the power supply 9 is an AC220V AC power supply. The power on and off of the entire test device is controlled by the main power switch 51. Under the action of the power converter 4, the internal power supply can simultaneously output DC3.3V, DC5V, DC12V, DC24V and AC220 voltages, thereby respectively powering the ultraviolet radiation source 32, the laser aligner 2, the infrared radiation source 31, the motor 3321 and the halogen lamp 331.

[0073] The laser aligner switch 52 is used to control the opening and closing of the laser aligner 2, the infrared radiation source switch 53 is used to control the opening and closing of the infrared radiation source 31, the ultraviolet radiation source switch 54 is used to control the opening and closing of the ultraviolet radiation source 32, the full-spectrum radiation source intensity knob 55 is used to control the radiation intensity of the halogen lamp 331 by adjusting the bidirectional thyristor 551, and the full-spectrum radiation source frequency knob 56 is used to control the motor 3321 to reciprocate at a specified step frequency by adjusting the frequency and duty cycle of PWM561, thereby driving the swinging fan blades 3322 to repeatedly block the halogen lamp 331 at a specified frequency to achieve the purpose of simulating the flickering characteristics of flames.

[0074] During operation, connect the power converter 4 to the power supply 9, press the main power switch 51 to power the entire test device; press the laser aligner switch 52, the laser aligner 2 emits a visible laser, and adjust the angle of the test socket 1 to align the visible laser with the fire detector to be tested; this operation can ensure that the radiation source can be fully covered by the fire detector to be tested, and ensure that the fire detector can receive the strongest trigger signal source.

[0075] For the infrared flame detector, when the infrared radiation source switch 53 is pressed, the test device can release an infrared signal source with a wavelength of 3-5nm and a frequency of 2-20Hz.

[0076] For the ultraviolet flame detector, by pressing the ultraviolet radiation source switch 54, the test device can release an ultraviolet signal source with a wavelength of 185-400nm.

[0077] For the red-ultraviolet composite flame detector, the infrared radiation source switch 53 and the ultraviolet radiation source switch 54 can be pressed simultaneously, and the test device can release the infrared and ultraviolet signal sources simultaneously.

[0078] For the image type flame detector, adjust the full spectrum radiation source intensity knob 55 and the full spectrum radiation source frequency knob 56. At this time, the test device can release a full spectrum signal source with a power of 100-1000W, a wavelength of 0.35-3.5μm, and a flickering frequency of 2-20Hz.

[0079] In some embodiments, see Figure 1 , Figure 2 , Figure 3 , Figure 4The fire detector action test device provided in the embodiment of the present application further includes a base 6, and the test seat 1 is rotatably connected to the base 6 via a horizontal rotation shaft 7. Exemplarily, the base 6 includes a horizontally arranged bottom plate 62 and a pair of side plates 63 fixed on the bottom plate 62, and the test seat 1 is arranged between the two side plates 63, and the two side plates 63 are rotatably connected to the test seat 1 via the horizontal rotation shaft 7. During operation, the base 6 can be placed on the foundation, and when the laser aligner 2 emits the laser, the angle of the test seat 1 is adjusted by controlling the test seat 1 to rotate around the horizontal rotation shaft 7, so that the laser can be quickly aligned with the fire detector.

[0080] For example, see Figure 1 , Figure 2 , Figure 3 , Figure 4 A locking mechanism 8 is provided between the base 6 and the test seat 1. Accordingly, by providing the locking mechanism 8, after the test seat 1 is adjusted to a specific angle, the test seat 1 can be locked to ensure that the test seat 1 will not be offset in angle due to external force or vibration during the test process, especially when a long-term test or a test in a complex environment is required, the accuracy and reliability of the test results can be ensured.

[0081] See also Figure 4 The locking mechanism 8 includes a locking shaft 81 and a locking nut 82. An arc groove 61 centered on the horizontal rotation axis 7 is provided on the base 6. One end of the locking shaft 81 is connected to the test seat 1, and the other end of the locking shaft 81 passes through the arc groove 61 and is threadedly connected to the locking nut 82. Exemplarily, the arc groove 61 is provided on the side plate 63. When the angle of the test seat 1 needs to be adjusted, it is only necessary to loosen the locking nut 82. When the locking nut 82 is separated from the side plate 63 of the base 6, the test seat 1 is controlled to rotate around the horizontal rotation axis 7, and the locking shaft 81 moves in the arc groove 61; when the angle adjustment of the test seat 1 is completed, it is only necessary to tighten the locking nut 82 until the locking nut 82 is tightly pressed against the side plate 63 of the base 6, so that the test seat 1 is locked at a specific angle.

[0082] In other embodiments, the locking mechanism 8 may also only include a locking bolt, which passes through the side plate 63 of the base 6 and is threadedly connected to the side plate 63 , and one end of the locking bolt is used to abut against the test socket 1 .
