Description
TECHNICAL FIELD
[0001] The utility model relates to icing detection technical field especially relates to an adjustable optical fiber type icing detector. BACKGROUND
[0002] With the influence of climate change and the increasing severity of seasonal icing problems, icing detection has become particularly important in many industries. Especially in the fields of aviation, transportation, power, communication and construction, icing phenomenon may have a significant impact on equipment operation, personnel safety and the stability of infrastructure. Therefore, the development of an efficient, accurate and adaptable icing detection device has become an urgent need for industry development. At present, the optical fiber type icing detector is widely used in icing detection due to its high sensitivity, fast response speed and other advantages. The device usually transmits optical signals through optical fibers and detects changes in optical signals through receivers to determine whether icing occurs on the surface. However, the traditional optical fiber type icing detector has some inherent technical problems, especially in terms of light source brightness adjustment and device adaptability, which limits its performance and reliability in complex environments. The traditional optical fiber type icing detector usually uses a fixed brightness light source. Although this design can work effectively in some specific environments, it often cannot maintain the best detection effect under changing environmental conditions. The thickness of the ice layer, reflectivity and ambient light intensity will all affect the transmission intensity of the optical signal.

In prior art 1, optical fiber type icing sensors are used to detect the thickness of the ice layer. These sensors are placed inside a specially designed housing, which has multiple arc surfaces with different radii. The detection end of each optical fiber type icing sensor has a unique cross-sectional radius, and these radii are arranged in increasing order.

[0030] Embodiment 1
[0031] Please refer to Figure 1The utility model embodiment provides a kind of adjustable optical fiber type icing detector.In traditional optical fiber type icing detector, the brightness of light source is usually preset and fixed, and the light source with fixed brightness cannot be adjusted according to different environmental conditions or different icing conditions.However, the thickness of ice, surface reflectivity and other factors will change with the change of environment, which may cause the light source with fixed brightness to have weak signal or high noise in some cases, thereby affecting the sensitivity and accuracy of the detector.In order to solve this problem, the utility model provides a kind of adjustable LED light source brightness setting.Through this adjustment setting, the sensitivity of the detector can be adjusted according to actual needs.Specifically, in cold and severe icing area, the brightness of the optical fiber sensor emitting end can be increased to ensure that clear signal can be obtained under harsh conditions;while in non-icing or warm environment, the brightness can be appropriately reduced to avoid unnecessary energy waste and reduce potential interference caused by too strong light source, thereby improving the accuracy of detector measurement.
[0032] Please refer to Figure 1 and Figure 2 In this embodiment, the adjustable optical fiber type icing detector includes a mounting plate 210 and a control circuit board 300 for adjusting the detection sensitivity of the icing detector 100.The arc top part of the control circuit board 300 is fixedly assembled with the mounting plate 210, ensuring that it can be stably set on the mounting plate 210.In addition, the control circuit board 300 can adjust and control the icing detector 100 to detect the degree of icing according to the actual detection environment.Such a setting enables the icing detector 100 to adapt to various detection environments and obtain accurate detection results according to the changes of these environments.
[0033] Please refer to Figure 1 and Figure 4 In this embodiment, the control circuit board 300 is arranged on the mounting plate 210, and the mounting plate 210 is further provided with a mobile power supply 310.The control circuit board 300 is electrically connected with the mobile power supply 310, ensuring the power supply required for normal operation of the control circuit board 300.In addition, the mobile power supply 310 is stably fixed on the mounting plate 210 to ensure its stability and safety during equipment operation.
[0034] Please refer to Figure 1, the icing detector 100 and the mobile power supply 310 are electrically connected with the control circuit board 300, ensuring the cooperative work of the whole system. The control circuit board 300 itself is an electronic component, which includes a microcontroller MCU, a MOSFET (Metal Oxide Semiconductor Field Effect Transistor) and an LED light source. The role of the LED light source is to provide the necessary light signal for the icing detector 100, which is essential for the normal work of the detector. The microcontroller MCU and the LED light source are connected with the gate and drain of the MOSFET respectively, which makes the microcontroller able to accurately control the brightness of the LED light source, and then adjust the intensity of the light signal provided by the LED light source for the icing detector 100.
[0035] The microcontroller MCU is the core unit of the control, which controls the MOSFET responsible for outputting the PWM signal (Pulse Width Modulation signal). The microcontroller MCU controls the gate of the MOSFET, and then adjusts the brightness of the LED light source. This adjustment mechanism makes the LED light source able to provide different intensity of light signal according to the needs, to adapt to different detection environment and conditions, ensuring that the icing detector 100 can accurately perform its detection task.
[0036] The microcontroller MCU is an Arduino or various types of single-chip microcomputer, which can output PWM signal to control the switching state of the MOSFET. In this way, the microcontroller can accurately adjust the brightness of the LED light source. The duty cycle of the PWM signal is a key parameter, which determines the proportion of time that the current flows in the LED light source. The higher the duty cycle, the longer the current flows, and thus the brightness of the LED light source is greater; on the contrary, if the duty cycle is reduced, the current flow time is reduced, and the brightness of the LED light source will be reduced accordingly.
[0037] In practical applications, the microcontroller MCU will adjust the duty cycle of the PWM signal according to different detection needs. For example, in the application of high sensitivity icing detection, by increasing the duty cycle of the PWM signal, the brightness of the LED light source can be increased, so as to more clearly observe the possible icing situation. While in the case of strong environmental light or relatively stable light conditions, in order to reduce energy consumption and avoid interference to the surrounding environment, the microcontroller will reduce the duty cycle of the PWM signal, thereby reducing the brightness of the LED light source, so as to adapt to the current detection needs.
[0038] Further, in other detection instruments, the arrangement of LED light sources may be fixed and cannot be adjusted; and fixed brightness LED light sources may cause excessive battery energy consumption in some cases, especially in mobile detection or unattended application scenarios, excessive power consumption may cause the device to be unable to work for a long time. In the embodiment, the brightness of the LED is adjusted by the microcontroller MCU outputting a PWM signal to control the MOSFET, and the power consumption is optimized. And when the icing detection demand is low, the LED brightness can be adjusted lower, thereby prolonging the battery usage time and improving the working efficiency of the system.
[0039] Further, in some complex environments, such as scenes with large temperature changes and strong light interference, fixed brightness light sources cannot adapt to changes in light environment, resulting in poor detection results. By adjusting the brightness of the LED light source, the detection instrument can adapt to different ambient light intensities. For example, in a strong light environment, the brightness of the LED light source is reduced; in a weak light environment, the brightness of the LED light source is increased, so that the detection instrument can adapt to different working conditions.
[0040] In addition, in the embodiment, the microcontroller MCU controls the MOSFET by outputting a PWM signal to adjust the brightness of the LED, which not only effectively reduces power consumption, but also flexibly adjusts the brightness according to actual detection needs. In the case of long-term operation of the detection instrument or battery power supply, such an adjustment mechanism is particularly important. By reducing the brightness of the LED, the battery consumption can be significantly reduced, thereby prolonging the operation time of the device and ensuring that the detection instrument can work continuously at critical moments, improving the overall working efficiency and reliability.
[0041] Further, the environmental adaptability problem is also considered in the embodiment. In different working environments, such as large temperature fluctuations or severe light interference, fixed brightness LED light sources often cannot meet the detection needs. Through the brightness adjustment mechanism provided in the embodiment, the detection instrument can automatically adjust the brightness of the LED light source according to the strength of the ambient light. In a strong light environment, reducing the brightness of the LED light source can reduce unnecessary energy consumption and avoid interference with the detection results caused by excessive light; while in a weak light environment, increasing the brightness of the LED light source can enhance the detection capability of the detection instrument, ensuring that clear and accurate detection data can be obtained in various complex environments, thereby improving the adaptability and detection accuracy of the detection instrument.
[0042] In the design of the control circuit board 300, in addition to other electronic components, a resistor is also arranged; the resistor is arranged between the microcontroller MCU and the gate of the MOSFET, and the main function thereof is to ensure the stability of the PWM signal during transmission, and to limit the current flowing through the LED light source, thereby protecting the LED light source from damage by the current, ensuring the normal operation of the entire circuit and prolonging the service life of the LED.
[0043] Further, the PWM signal is generated by the microcontroller, the PWM signal controls the MOSFET, and in turn controls the current flowing through the LED light source. The duty ratio of the PWM signal directly affects the brightness of the LED, and changing the duty ratio can adjust the brightness. The source of the MOSFET is grounded, the drain is connected to the negative pole of the LED, and the positive pole of the LED is connected to the positive pole of the power supply. By adjusting the duty ratio of the PWM signal, the on-time of the MOSFET and the current of the LED can be changed, thereby realizing brightness adjustment.
[0044] Further, in the present embodiment, an operational amplifier can also be arranged in the control circuit board 300, which can amplify the output signal of the photodetector to ensure that the signal strength is suitable for further processing.
[0045] Embodiment 2
[0046] Please refer to Figure 1 In the embodiment of the utility model, the movable part of the adjustable optical fiber type icing detector 100 is provided, so that the icing detector 100 can be moved for detection, and not only the detection sensitivity of the icing detector 100 can be adjusted, but also the detection range of the icing detector 100 can be adjusted.
[0047] Please refer to Figure 1 、 Figure 2 and Figure 3 The adjustable optical fiber type icing detector 100 comprises a top plate 220, a mounting plate 210 and a shell 230, and the top plate 220, the mounting plate 210 and the shell 230 are connected together in a detachable manner. The top plate 220, the mounting plate 210 and the shell 230 are arranged in such a way that they can be assembled into an integral structure. In addition, the control circuit board 300 and the mobile power supply 310 can be arranged in the internal space in this structural design, so as to ensure that the detector will not be disturbed by external environmental factors during operation, and to ensure its stability and reliability.
[0048] Please refer to Figure 1On the mounting plate 210, the control circuit board 300 and the mobile power supply 310 are both waterproofed. Since the icing detector 100 usually performs detection in a relatively humid environment, it is particularly important to waterproof the control circuit board 300 and the mobile power supply 310; such treatment ensures that the icing detector 100 can normally perform its icing detection work even in harsh environmental conditions, thereby ensuring the stable operation of the equipment and the accuracy of the detection.
[0049] Please refer to Figure 2 The icing detector 100 includes at least two detection probes 113 arranged at the two ends of the mounting plate 210. These probes are arranged to extend away from the top plate 220, ensuring that they can cover a wider detection area.
[0050] In addition, the icing detector 100 is also equipped with a detection optical fiber 110 composed of a transmitting optical fiber bundle 111 and a receiving optical fiber bundle 112. The LED light source of the detector is responsible for providing detection light 114, which enters the interior of the icing detector 100 through the transmitting optical fiber bundle 111 and is then received by the receiving optical fiber bundle 112 from the surface to be detected.
[0051] In this embodiment, for the detection principle of the icing detector 100, please refer to the detection principle of the JS-GD series optical fiber icing sensor developed by Shanghai Jingli Electronic Technology Development Co., Ltd. This series of sensors uses advanced optical fiber sensing technology to determine icing conditions by detecting changes in the propagation characteristics of light in the optical fiber.
[0052] The optical fiber icing sensor is a sensor for detecting the thickness of ice on the surface of objects such as aircraft, power transmission lines, buildings, roads, and wind turbine blades, and its application in these scenarios is relatively mature. Generally, the icing sensor can convert the icing signal into an electrical signal that can be directly detected. The optical fiber icing sensor uses two concentric optical fibers, with the central circular shape being a transmitting optical fiber that can emit infrared light, and the peripheral circular shape being a receiving optical fiber that can accept and detect scattered and reflected infrared light. The end face of the optical fiber probe is a flat glass, and when there is no ice on the glass, the infrared light emitted by the transmitting optical fiber passes through the glass end face into the air, and the receiving optical fiber cannot receive any infrared light. When there is ice on the glass end face, part of the infrared light emitted by the transmitting optical fiber is scattered and reflected by the ice layer and is received by the receiving optical fiber. By detecting the strength of the received infrared light by the receiving optical fiber, the purpose of detecting icing is achieved.
[0053] In order to ensure that the probe and the surface to be detected to maintain a predetermined detection interval, so that the emission fiber bundle 111 emitted detection light 114 can be in a good way back, and to ensure that these reflected light can be received by the optical fiber bundle 112 accurately captured and received.
[0054] Please see Figure 3 And Figure 5 In this embodiment, in order to make the ice detection instrument 100 can be moved on the road 410, self moving ice surface 420 for ice detection; thus, so that the ice detection instrument 100 has mobility, so that the device can be flexible in a variety of environments for work. In order to achieve this goal, the two sides of the mounting plate 210 are respectively provided with the first drive wheel 242 and the second drive wheel 243 with drive motor 241; the setting of the two drive wheels allows the ice detection instrument 100 to maintain good mobility on different ground. The first drive wheel 242 and the second drive wheel 243 can be synchronized or individually moved, which makes the ice detection instrument 100 more flexible to adjust its direction and speed when encountering obstacles or needing to turn or needing to detect ice in other areas. The first drive wheel 242 and the second drive wheel 243 are respectively driven by the respective drive motor 241, which ensures that each wheel can be independently and accurately controlled.
[0055] Further, please see Figure 2 In order to ensure the stability and safety of the ice detection instrument 100 during detection, the lowest height of the ice detection instrument 100 is set to be not lower than the lowest height of the first drive wheel 242 and the second drive wheel 243. Such setting is considered to avoid the ice detection instrument 100 in the moving process with the detection surface directly, so as to avoid unnecessary damage to the detection surface or affect the accuracy of the detection result. Through such design, the ice detection instrument 100 can accurately detect the icing condition of the surface without contacting the detection surface.
[0056] In the mounting plate 210 structure of the embodiment, the first universal wheel 244 and the second universal wheel 245 are respectively arranged at both ends of the mounting plate 210. The two universal wheels not only can provide the guiding function in different directions, but also can provide necessary support for the whole device.
[0057] In addition, the two ends of the top plate 220 are also respectively provided with the first shooting unit 246 and the second shooting unit 247; the two shooting units are connected with the control circuit board 300. By combining the ice detection instrument 100 and the two shooting units, a double detection mechanism can be realized, so that the detection result is more accurate and reliable.
[0058] Traditional optical fiber icing detectors usually need to be manually held or fixedly installed, which limits their detection range and flexibility. The trolley-mounted design in this embodiment allows the device to move freely along a predetermined path, covering a larger area for detection. The trolley itself can carry multiple detection probes, allowing for multi-point detection and more comprehensive and efficient acquisition of icing data.
[0059] In road, railway, airport and other transportation facilities, icing is one of the main factors affecting traffic safety. The trolley-mounted icing detector can patrol along the road, railway track or airport runway area to detect icing or snow problems in time. Compared with the traditional manual patrol method, the automatic icing detector mounted on the trolley can more efficiently and comprehensively perform real-time monitoring to avoid traffic accidents caused by icing. Especially in large areas such as airports, icing detection on the runway has a great impact on aircraft take-off and flight safety. Traditional icing detection methods often rely on manual or fixed detection equipment, which is inefficient and costly, and it is difficult to cover the entire range. By using this trolley-mounted icing detector, it can detect all aspects of the runway and aircraft wings and provide real-time feedback to help airlines better perform pre-flight safety checks.
[0060] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art
[0061] Ordinary skilled person should understand: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
