Description

Technical Field

[0001] The invention relates to the technical field of infrared thermal imaging temperature measuring devices, and in particular to an external ready-to-use infrared thermal imaging temperature measuring device for a mobile phone and a working method thereof. Background Art

[0002] The infrared thermal imaging temperature measuring device is a device used to detect the temperature distribution on the surface of an object. It uses the blackbody radiation law that all objects with a temperature higher than absolute zero will emit infrared radiation, and there is a specific relationship between the temperature of an object and the intensity of the infrared radiation it emits. By detecting, analyzing and processing the infrared radiation emitted by the object, the temperature distribution on the surface of the object can be detected.

[0003] Most existing infrared thermal imaging temperature measurement devices collect infrared radiation by setting up a detection head. However, most of the detection heads lack effective protection structures and are easily hit and worn during carrying and use, affecting their service life and measurement accuracy. At the same time, cleaning the temperature measuring head is also a common problem. If it is not cleaned in a timely and effective manner, it may lead to inaccurate measurement results. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art in that the detection head of an infrared thermal imaging temperature measuring device for collecting infrared radiation lacks an effective protective structure and a corresponding cleaning function, and to provide a mobile phone external ready-to-use infrared thermal imaging temperature measuring device and a working method thereof. For the portable mobile phone external ready-to-use infrared thermal imaging temperature measuring device, a protective shell whose opening and closing is controlled by a magnet is provided to provide protection for the detection head of a thermometer in the infrared thermal imaging temperature measuring device to prevent the thermometer detection head from being damaged by the outside world, and a sponge strip for cleaning the detection head is provided to ensure that the detection head is always in the best working state, accurately detect the infrared radiation emitted by the object and convert it into a thermal image, avoid the influence of dirt on the reception and conversion ability of infrared radiation, and ensure the accuracy of the temperature measurement result.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] An external ready-to-use infrared thermal imaging temperature measuring device for a mobile phone comprises a thermometer body, a handle and a protective shell, wherein a control key is arranged on the side of the thermometer body, a connecting block is fixedly installed on the side of the protective shell, a connecting rod is fixedly installed on the side of the protective shell, a magnet A is fixedly installed on one end of the connecting rod, a fixed block is fixedly installed on the surface of the thermometer body, a magnet B is arranged on the surface of the thermometer body, an L-plate is rotatably connected to the side of the thermometer body, the internal thread of the L-plate is connected to a limit rod, a cleaning plate is slidably connected to the inside of the protective shell, a sponge strip is arranged on the side of the cleaning plate, a sliding block is fixedly connected to the side of the cleaning plate, a moving block is fixedly connected to the side of the cleaning plate, and a slide groove is provided inside the protective shell.

[0007] By separating magnet A and magnet B, and then flipping the protective shell to completely cover the thermometer detection head, the detection head can be protected from physical damage such as collision and scratches from the outside. When the moving block is grasped and slid back and forth, the sponge strip on the surface of the cleaning plate cleans the surface of the thermometer detection head, thereby ensuring that the detection head is always in the best working condition, accurately detecting the infrared radiation emitted by the object and converting it into a thermal image, and avoiding the influence of dirt on the reception and conversion ability of infrared radiation.

[0008] Furthermore, the connecting block is rotatably connected to the fixing block, and the limiting rod is threadably connected to the protective shell.

[0009] By optimizing the design of the protective shell structure, it is ensured that when the temperature measuring device is not in working state, the detection head can be screwed into the protective shell through the limit rod and fixed, so as to ensure the protective effect of the protective shell on the detection head.

[0010] Furthermore, the magnet A and the magnet B are attracted to each other, and the sliding block is slidably connected to the sliding groove.

[0011] Furthermore, the moving block is slidably connected to the protective shell, and the side surface of the moving block is provided with anti-slip grooves.

[0012] When the temperature measuring device is in working state, the protective shell can be opened and fixed by adsorbing magnet A and magnet B to facilitate the use of the detection head. After opening the protective shell, the detection head can be cleaned by moving the moving block on the protective shell, and anti-slip grooves are set on the moving block to optimize the use of the moving block.

[0013] Furthermore, a storage box is fixedly installed on the side of the handle, a wire entry slot is opened on the side of the storage box, a winding pole is fixedly installed inside the storage box, a wire clamp is fixedly installed inside the storage box, a flip cover is rotatably connected to the inner side of the storage box, a rotating rod is symmetrically fixedly installed on the side of the flip cover, a magnet C is rotatably connected to the inner side of the flip cover, and a magnet D is provided on the side of the storage box.

[0014] Furthermore, the number of the winding poles and the wire clamps is two groups, and the rotating rod is rotationally connected to the storage box.

[0015] Furthermore, the magnet C and the magnet D are attracted to each other.

[0016] The design of the winding post and the wire clip allows users to easily wind the transmission line or other wire harnesses on the winding post and use the wire clip to fix it in a suitable position, avoiding the transmission line from being tangled around the device in a disorderly manner, making the device look neater, and also making it convenient to quickly find the transmission line and unfold it the next time it is used. The design of magnet C and magnet B can ensure that the flip cover can fit tightly against the storage box when closed, preventing the cover from being accidentally opened during carrying.

[0017] Furthermore, a signal processing module and a signal output interface are also provided on the thermometer body. The signal processing module is electrically connected to the thermometer detection head, and the signal processing module is also communicatively connected to an external mobile phone via the signal output interface.

[0018] In order to improve the portability of the optimized temperature measuring device, a corresponding signal output interface is provided, through which communication connection with an external mobile phone can be realized. The collected data can be directly transmitted to the external mobile phone for display, which can provide more intuitive and timely feedback on the temperature measurement results.

[0019] The working method of the mobile phone external ready-to-use infrared thermal imaging temperature measuring device includes:

[0020] Obtain the target temperature measurement object and select the detection point of the target temperature measurement object;

[0021] Establish a communication connection between the thermometer and an external mobile phone through the signal output interface;

[0022] Adsorb magnet A and magnet B, combine with control keys, and collect infrared signals of each detection point through the thermometer detection head;

[0023] The infrared signals of each detection point are processed to construct the thermal image data of the target temperature measurement object, and the thermal image data is transmitted to an external mobile phone for display.

[0024] For different temperature measurement purposes of the temperature measurement object, the location where the corresponding temperature characteristics are displayed is different according to the operating characteristics of the equipment. Therefore, before performing temperature measurement, a specific detection point is selected first, and then the temperature measurement process is performed on the detection point to achieve overall temperature measurement of the target temperature measurement object.

[0025] Furthermore, the signal processing of the infrared signal of each detection point to construct thermal image data of the target temperature measurement object includes:

[0026] Preprocess the infrared signal of each detection point, and perform digital signal processing on the preprocessed infrared signal to obtain image data corresponding to each detection point;

[0027] Correcting the temperature error in the image data corresponding to each detection point;

[0028] All image data are integrated according to the position of each detection point to construct the thermal image data of the target temperature measurement object.

[0029] In order to ensure the accuracy of the temperature measurement data, the temperature measurement data of different detection points are collected to form the overall thermal image data of the target temperature measurement object, so as to fully display the temperature of the target temperature measurement object and facilitate the subsequent intuitive display in the external mobile phone. When generating the corresponding measured data, temperature calibration and other processing are performed to ensure the accuracy of the thermal image data displayed later.

[0030] The beneficial effects of the present invention are:

[0031] (1) By separating magnet A and magnet B, and then flipping the protective shell to completely cover the thermometer detection head, the detection head is protected from physical damage such as collision and scratches from the outside.

[0043] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0044] Embodiment 1:

[0045] Power equipment in operation is affected by factors such as installation and weather, and is prone to problems such as increased contact resistance, reduced insulation resistance, and increased dielectric loss. These problems can be reflected by changes in the local temperature of the equipment. By analyzing the infrared image of the equipment, the operating status of the equipment can be understood, and the problems existing in the equipment can be preliminarily analyzed and judged based on different infrared defect maps.

[0046] Therefore, in order to ensure the safe operation of power equipment, the temperature of the power equipment can be obtained through infrared temperature measurement, so as to obtain the fault status of the power equipment in time.

[0047] In response to the above requirements, Figure 1-Figure 6 As shown, this embodiment shows a mobile phone external ready-to-use infrared thermal imaging temperature measuring device, including a thermometer body 1, a handle 2 and a protective shell 3, the side of the thermometer body 1 is provided with a control key 4, the side of the protective shell 3 is fixedly installed with a connecting block 5, the side of the protective shell 3 is fixedly installed with a connecting rod 6, one end of the connecting rod 6 is fixedly installed with a magnet A7, the surface of the thermometer body 1 is fixedly installed with a fixed block 8, the surface of the thermometer body 1 is provided with a magnet B9, the side of the thermometer body 1 is rotatably connected with an L plate 10, the internal thread connection of the L plate 10 is connected with a limit rod 11, the internal sliding connection of the protective shell 3 is provided with a cleaning plate 12, the side of the cleaning plate 12 is provided with a sponge strip 13, the side of the cleaning plate 12 is fixedly connected with a sliding block 14, the side of the cleaning plate 12 is fixedly connected with a moving block 15, and the interior of the protective shell 3 is provided with a slide groove 17. The connecting block 5 is rotatably connected with the fixed block 8, and the limit rod 11 is threadedly connected with the protective shell 3. The magnet A7 and the magnet B9 are attracted to each other, and the sliding block 14 is slidably connected to the sliding groove 17. The moving block 15 is slidably connected to the protective shell 3, and the side of the moving block 15 is provided with anti-slip grooves 16.

[0048] Before the device is not in use, the magnet A7 and the magnet B9 can be separated, and then the protective shell 3 can be turned over to completely cover the thermometer detection head, and then the limit rod 11 can be rotated to screw it into the protective shell 3 to mechanically fix it, thereby preventing the thermometer detection head from being physically damaged by external collisions, scratches, etc.

[0049] When the device is used, the protective shell 3 can be turned over again, and the protective shell 3 can be fixed by the mutual adsorption of the magnet A7 and the magnet B9, and the temperature can be measured by the thermometer detection head.

[0050] Among them, the control keys set on the side of the thermometer include the power control button and the temperature measurement control button of the thermometer. When the power control button is pressed, the thermometer is started. After determining the temperature measurement detection point and reaching the corresponding position, press the temperature measurement control button to achieve temperature measurement and reduce the energy consumption of the thermometer.

[0051] During use, if there are stains or dust on the surface of the thermometer detection head, there is no need to use additional cleaning tools. By sliding the movable block 15 back and forth, the sponge strip 13 on the surface of the cleaning plate 12 can clean the surface of the thermometer detection head, thereby ensuring that the detection head is always in the best working condition and avoiding the impact of dirt on the detector's ability to receive and convert infrared radiation.

[0052] A storage box 18 is fixedly installed on the side of the handle 2, a wire entry slot 19 is opened on the side of the storage box 18, a winding post 20 is fixedly installed inside the storage box 18, a wire clamp 21 is fixedly installed inside the storage box 18, a flip cover 22 is rotatably connected to the inner side of the storage box 18, a rotating rod 23 is symmetrically fixedly installed on the side of the flip cover 22, a magnet C24 is rotatably connected to the inner side of the flip cover 22, and a magnet D25 is provided on the side of the storage box 18.

[0053] The number of the winding pole 20 and the wire clamp 21 is two sets, and the rotating rod 23 is rotatably connected to the storage box 18 .

[0054] The magnet C24 and the magnet D25 are attracted to each other.

[0055] When realizing the communication connection between the thermometer and an external mobile phone, it is mostly necessary to use a signal transmission line to realize the communication connection, and a power line may also be needed to realize power supply during use. These cables can be wound on the winding pole 20 and fixed in a verified position using a wire clamp 21, thereby avoiding the cables from being tangled around the device in a disorderly manner. When used later, the required cables can also be quickly obtained and unfolded, thereby improving the use efficiency. Magnets C24 and D25 are provided, and through the mutual adsorption of magnets C24 and D25, it can be ensured that the flip cover 22 can fit tightly against the storage box 18 when closed, preventing the cover from accidentally opening during carrying.

[0056] The thermometer body 1 is also provided with a signal processing module and a signal output interface. The signal processing module is electrically connected to the thermometer detection head. The signal processing module is also connected to an external mobile phone for communication via the signal output interface.

[0057] In order to improve the temperature measurement efficiency, a signal processing module is set in the thermometer, which can convert the collected infrared radiation signal into an electrical signal that is easy to process directly. After further amplification and processing, the temperature value or temperature field distribution on the surface of the equipment can be displayed in the form of digital or two-dimensional thermal images.

[0058] In order to be able to transmit the temperature measurement results in time, a corresponding signal output interface is set up, and a communication connection can be established with an external mobile phone through the signal output interface to transmit the collected temperature measurement data in real time and obtain the fault status of the power equipment in time.

[0059] Embodiment 2:

[0060] Based on the mobile phone external ready-to-use infrared thermal imaging temperature measuring device shown in Example 1, this embodiment also shows the working method of the mobile phone external ready-to-use infrared thermal imaging temperature measuring device, such as Figure 7 As shown, including:

[0061] Obtain the target temperature measurement object and select the detection point of the target temperature measurement object;

[0062] Establish a communication connection between the thermometer and an external mobile phone through the signal output interface;

[0063] Adsorb magnet A7 and magnet B9, combine with control key 4, and collect infrared signals of each detection point through the temperature measuring head;

[0064] The infrared signals of each detection point are processed to construct the thermal image data of the target temperature measurement object, and the thermal image data is transmitted to an external mobile phone for display.

[0065] For different temperature measurement purposes of the target temperature measurement object, the location where the corresponding temperature characteristics are displayed is different according to its equipment operation characteristics. Therefore, before performing temperature measurement, first determine the possible equipment failure type according to the equipment type, and then select the equipment location that displays the temperature characteristics corresponding to the various equipment failure types, and then determine the specific detection points, and then perform temperature measurement on the detection points to achieve overall temperature measurement of the target temperature measurement object and achieve comprehensive fault identification of the target temperature measurement object.

[0066] Taking the transformer as an example, when the transformer is working, its winding and core will generate heat due to electromagnetic induction, and the oil in the oil tank will also heat up due to heat conduction. Therefore, specific detection points can be selected according to the location of the transformer winding, the location of the core and the location of the oil tank.

[0067] And considering that infrared thermal imaging temperature measuring devices are generally used outdoors, the ambient temperature varies greatly, and the temperature measuring device is generally required to have good thermal stability. Therefore, when selecting the detection point, it is necessary to stay away from the high temperature area of ​​the equipment and select a place where the temperature of the corresponding circuit of the equipment is relatively low for temperature measurement, which can generally be below 80°C, thereby reducing the high temperature resistance requirements of the temperature measuring device. Corresponding temperature compensation can also be set in the signal processing module of the infrared thermal imaging temperature measuring device to further improve the thermal stability of the infrared thermal imaging temperature measuring device.

[0068] In order to realize the real-time transmission of temperature measurement data, a communication connection is established between the thermometer and the external mobile phone, and then subsequent temperature measurement operations are carried out.

[0069] After the protective shell 3 is opened, the magnet A7 and the magnet B9 are attracted to fix the protective shell 3, and then the temperature measurement of each detection point is realized by operating the control key 4.

[0070] The thermometer detection head is generally composed of an infrared detector and a black radiation device, which can sense the infrared rays emitted by an object and convert them into electrical signals. After pressing the control key 4, the infrared detector in the thermometer detection head can be triggered to receive the infrared radiation emitted by the surface of the target temperature measurement object, and then convert the infrared signal into an electrical signal. After signal processing such as amplification and filtering, the corresponding thermal image data can be obtained to achieve temperature measurement of the target temperature measurement object.

[0071] The signal processing of the infrared signal of each detection point to construct the thermal image data of the target temperature measurement object includes:

[0072] Preprocess the infrared signal of each detection point, and perform digital signal processing on the preprocessed infrared signal to obtain image data corresponding to each detection point;

[0073] Correcting the temperature error in the image data corresponding to each detection point;

[0074] All image data are integrated according to the position of each detection point to construct the thermal image data of the target temperature measurement object.

[0075] For the infrared radiation emitted by the surface of the target temperature measurement object, the collected infrared signal is usually weak, so it is first converted into an electrical signal that is easier to process and then amplified by an amplifier. At the same time, in order to eliminate noise and interference in the environment, the amplified electrical signal is further filtered.

[0076] In order to realize the subsequent thermal image analysis, the electrical signal after filtering is converted into a digital signal by analog-to-digital conversion to complete the preprocessing. The digital signal after analog-to-digital conversion is the image data.

[0077] The acquired image data also needs to undergo a further step of image enhancement, image smoothing, and edge detection to improve the clarity and contrast of the thermal image.

[0078] At the same time, considering the impact of factors such as environmental noise and instrument performance changes on the collected data, the image data needs to be further corrected, such as applying an ambient temperature compensation algorithm and adjusting gain parameters to achieve image data correction.

[0079] Subsequently, the image data of each detection point is integrated according to the specific location of each detection point to form complete thermal image data of the target temperature measurement object, and then transmitted to an external mobile phone for display to identify abnormal temperature areas and quickly obtain equipment failure conditions.

[0080] The above-described embodiment is only a preferred solution of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solution described in the claims.
