Description

Technical Field

[0001] This invention relates to the field of temperature detection technology, and in particular to a three-dimensional medium temperature identification method, a medium temperature identification device, a medium temperature identification system, and a computer-readable storage medium. Background Technology

[0002] Temperature is a parameter that reflects the degree of hotness or coldness of a medium, and it is one of the important parameters in processing, production, medical testing, and other processes. Current temperature measuring instruments use temperature sensing elements and electromagnetic radiation to complete the detection, which can achieve non-contact temperature measurement and is relatively convenient to use.

[0003] However, current non-contact temperature measurement devices can only detect the surface temperature of the medium, and the final medium temperature image they construct is also a two-dimensional image. For media with multi-layered structures, existing technologies cannot accurately characterize the temperature of each layer below the surface, thus failing to fully construct a three-dimensional temperature image of the medium and making it difficult to meet the higher requirements for precise control of the overall temperature of the medium. Summary of the Invention

[0004] The main objective of this invention is to provide a three-dimensional medium temperature identification method for use in energy detection components. The three-dimensional medium temperature identification method includes the following steps:

[0005] The target energy line is emitted toward the target medium; wherein the target energy line is any one of infrared energy line, laser energy line, and radio frequency energy line.

[0006] Receive the target energy line reflected by the target medium at a preset location point to obtain the corresponding first received power value, and use the first received power value at multiple preset time nodes as the first node power value.

[0007] A first dielectric layer temperature value is obtained based on the power value of each first node.

[0008] Based on the correspondence between the preset time node and the depth of the target medium, a first mapping relationship is established between the depth of the medium and the temperature value of the first medium layer to obtain a three-dimensional temperature image of the medium.

[0009] Further, the step of obtaining a first dielectric layer temperature value corresponding to each of the first node power values ​​includes:

[0010] Each of the first node power values ​​is sequentially used as the target power value, and the power value of the first node that is prior to the target power value is obtained as the base power value;

[0011] By subtracting the corresponding base power value from the target power value, a dielectric layer reflection power value is obtained based on each target power value.

[0012] A temperature value of the first dielectric layer is obtained based on the reflection power value of each dielectric layer.

[0013] Further, the step of subtracting the corresponding base power value from the target power value to obtain a dielectric layer reflection power value based on each target power value includes:

[0014] The current repetitive power value is obtained by multiplying the base power value by a preset conversion parameter; wherein the preset conversion parameter is used to characterize the degree of attenuation of the target energy line in the target medium;

[0015] By subtracting the corresponding current repetition power value from the target power value, a dielectric layer reflection power value is obtained based on each target power value.

[0016] Furthermore, prior to the step of emitting the target energy line into the target medium, the following steps are included:

[0017] Establish a correlation table between the reflected power value of the dielectric layer and the temperature value of the dielectric layer;

[0018] The step of obtaining a temperature value of the first dielectric layer based on the reflection power value of each dielectric layer includes:

[0019] Based on the reflection power value of each dielectric layer, the corresponding temperature value of the first dielectric layer is looked up in the association table.

[0020] Furthermore, the step of establishing a correlation table between the dielectric layer reflection power value and the dielectric layer temperature value includes:

[0021] Establish a correlation table between the target energy line wavelength, the reflected power value of the dielectric layer, and the temperature value of the dielectric layer.

[0022] Further, before the step of establishing a first mapping relationship between the medium depth and the temperature value of the first medium layer based on the correspondence between the preset time node and the medium depth of the target medium to obtain a three-dimensional temperature image of the medium, the following steps are included:

[0023] The wavelength value of the target energy line is switched, and the target energy line is emitted to the target medium; the target energy line reflected by the target medium is received at the preset position point to obtain the corresponding second received power value, and the second received power value at multiple preset time nodes is used as the second node power value; a second medium layer temperature value is obtained based on each second node power value.

[0024] The step of establishing a first mapping relationship between the medium depth and the temperature value of the first medium layer based on the correspondence between the preset time node and the medium depth of the target medium, so as to obtain a three-dimensional temperature image of the medium, includes:

[0025] Based on the correspondence between the preset time node and the depth of the target medium, a second mapping relationship is established between the depth of the medium and the temperature value of the second medium layer;

[0026] Based on the first mapping relationship and the second mapping relationship, a three-dimensional temperature image of the medium is constructed.

[0027] Further, the energy detection component includes a photoelectric sensing device; the step of receiving the target energy line reflected by the target medium at a preset location point to obtain the corresponding first received power value includes:

[0028] The photoelectric sensing device receives the target energy line reflected by the target medium at the preset position point and converts it into a photocurrent signal.

[0029] Obtain the first received power value corresponding to the photocurrent signal.

[0030] Correspondingly, the present invention also proposes a three-dimensional medium temperature identification device, the three-dimensional medium temperature identification device comprising:

[0031] The transmission module is used to transmit target energy lines to the target medium.

[0032] The conversion module is used to receive the target energy line reflected by the target medium at a preset location point to obtain the corresponding first received power value, and to use the first received power value at multiple preset time nodes as the first node power value.

[0033] The calculation module is used to obtain a first dielectric layer temperature value based on the power value of each first node.

[0034] The construction module is used to establish a first mapping relationship between the medium depth and the temperature value of the first medium layer based on the correspondence between the preset time node and the medium depth of the target medium, so as to obtain a three-dimensional temperature image of the medium.

[0035] Correspondingly, the present invention also proposes a three-dimensional medium temperature identification system, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, it implements the steps of the three-dimensional medium temperature identification method as described above.

[0036] Correspondingly, the present invention also proposes a computer-readable storage medium storing a three-dimensional medium temperature identification program, wherein the three-dimensional medium temperature identification program, when executed by a processor, implements the steps of the three-dimensional medium temperature identification method as described above.

[0037] The three-dimensional medium temperature identification method provided by this invention changes the traditional method of passive temperature measurement based on the radiation energy of the target medium (such as the radiation energy of the human body). By actively transmitting target energy lines (including infrared energy lines, laser energy lines, and radio frequency energy lines) to the target medium, and utilizing the time difference of the target energy lines in the target medium and the characteristic that the target energy lines reach different depth levels of the target medium at different times and are reflected, a preset location point is selected. The target energy lines reflected by the target medium to the preset location point at different time points are received, and the power values ​​corresponding to each time point are obtained. These multiple power values ​​can characterize the reflected energy of each depth level. Based on the coupling relationship between the reflected energy of each depth level and the current temperature of that depth level, the medium layer temperature value of each depth level is derived. Thus, a first mapping relationship between the medium depth and the current temperature value at each depth level can be established. Finally, a three-dimensional temperature image of the medium that can characterize the temperature information of each depth level of the target medium is constructed through temperature development and other technologies. The above technical solution can overcome the shortcomings of current non-contact temperature measurement devices, which can only detect the surface temperature of the target medium and can only construct a two-dimensional temperature image of the target medium. It can accurately reflect the current temperature at each depth level in a multi-layered target medium and construct a three-dimensional temperature image of the target medium, so that users can more accurately control the overall temperature of the target medium in the process of processing, production, medical testing and other processes.

[0052] Reference Figures 1 to 3 This invention provides a three-dimensional medium temperature identification method applied to an energy detection component. The energy detection component includes a measurement probe, which includes at least one energy line light source 2 capable of multi-point precise positioning and at least one light receiver. The energy line light source 2 and the light receiver are located on the same side of the target medium 1. The three-dimensional medium temperature identification method includes the following steps:

[0053] S1, emit target energy lines to target medium 1; wherein, target medium 1 can be any medium with a multi-level structure, each level of which can be partially penetrated by the target energy lines, and each level of which can absorb and reflect a portion of the target energy lines, such as human skin with stratum corneum, epidermis, dermis, and subcutaneous tissue; the target energy lines can be infrared energy lines, laser energy lines, or radio frequency energy lines, which can be emitted by energy line light source 2. Specifically, taking infrared as an example, energy line light source 2 can include an infrared transmitter, which is equipped with a corresponding optical system. Under the excitation of the power supply, the infrared light in the infrared transmitter emits a series of modulated infrared beams to target medium 1;

[0054] S2, receive the target energy line reflected by the target medium 1 at a preset location point to obtain the corresponding first received power value, and use the first received power value at multiple preset time nodes as the first node power value.

[0055] Optionally, the energy detection component includes a photoelectric sensing device 3; step S2 includes:

[0056] S21, the photoelectric sensor 3 receives the target energy line reflected by the target medium 1 at a preset position point and converts it into a photocurrent signal;

[0057] S22, obtain the first received power value corresponding to the photocurrent signal; specifically, the photocurrent signal can be processed by the circuit and transmitted to the back-end processing system 4. After signal processing, the photocurrent signal can be digitized to obtain the corresponding first received power value and can be displayed on the display 5.

[0058] For example, first, a preset location point is selected; the preset time points may include three time points: 0.1s, 0.2s, and 0.3s (corresponding to...). Figure 1 (as shown in T1, T2, and T3). Correspondingly, at 0.1s, the target energy line reflected by the target medium 1 is received at the aforementioned preset position point and a corresponding first received power value a1 is obtained; at 0.2s, the target energy line reflected by the target medium 1 is received at the aforementioned preset position point and a corresponding first received power value a2 is obtained; at 0.3s, the target energy line reflected by the target medium 1 is received at the aforementioned preset position point and a corresponding first received power value a3 is obtained; wherein, the optical signal corresponding to the received target energy line can be converted into an electrical signal through photoelectric conversion technology, thereby obtaining the first received power values ​​a1, a2, and a3.

[0059] Based on the transmission rate of the target energy line in the target medium 1, at 0.1s, the target energy line reaches the first depth level 11 in the target medium 1. Part of the target energy line is reflected at the first depth level 11, and the other part of the target energy line will pass through the first depth level 11 and continue to be projected forward. That is, what is received at this time is the target energy line reflected by the first depth level 11 at 0.1s. The first received power value a1 obtained thus represents the reflected energy reflected by the first depth level 11 to the preset position point at 0.1s. At 0.2s, the target energy line reaches the second depth level 12 in the target medium 1. Part of the target energy line is reflected at the second depth level 12, and the other part of the target energy line will pass through the second depth level 12 and continue to be projected forward. That is, what is received at this time is the target energy line reflected by the first depth level 11 at 0.2s. The sum of the target energy lines reflected by layer 11 and the second depth layer 12, thus obtaining the first received power value a2, represents the sum of the reflected energy reflected by the first depth layer 11 and the second depth layer 12 to the preset position point at 0.2s; at 0.3s, the target energy line reaches the third depth layer 13 in the target medium 1, part of the target energy line is reflected at the third depth layer 13, and the other part of the target energy line will pass through the third depth layer 13 and continue to be projected forward, that is, what is received at this time is the sum of the target energy lines reflected by the first depth layer 11, the second depth layer 12, and the third depth layer 13 at 0.3s, thus obtaining the first received power value a3, which represents the sum of the reflected energy reflected by the first depth layer 11, the second depth layer 12, and the third depth layer 13 to the preset position point at 0.3s.

[0060] S3, based on the power value of each first node, a first dielectric layer temperature value is obtained respectively;

[0061] Since the energy of the target energy line reflected by each depth layer in the target medium 1 has a predictable coupling relationship with the current temperature of that depth layer, and the first received power values ​​obtained in the aforementioned steps can also characterize the reflected energy status of each depth layer, the first medium layer temperature value of each depth layer can be derived based on the above coupling relationship and the corresponding first received power values; the specific derivation method is not limited here.

[0062] S4. Based on the correspondence between the preset time node and the depth of the target medium, establish a first mapping relationship between the depth of the medium and the temperature value of the first medium layer to obtain a three-dimensional temperature image of the medium.

[0063] The correspondence between the preset time nodes and the depth of the target medium 1 can be determined based on the transmission rate of the target energy line. After determining the specific depths of the first depth level 11, the second depth level 12, and the third depth level 13 reached by the target energy line at the three time points of 0.1s, 0.2s, and 0.3s respectively, each specific depth can be associated with the temperature values ​​of each first medium layer obtained at the preset location points to establish a first mapping relationship. Based on this first mapping relationship, a three-dimensional temperature image of the medium that can characterize the temperature information at each depth level of the target medium 1 can be constructed using techniques such as temperature development.

[0064] In practical applications, taking human skin as the target medium 1 as an example, human skin is divided into the stratum corneum, epidermis, and dermis from the outside in. When the target energy rays irradiate the skin, some of the target energy rays are reflected, and some penetrate into the skin. The degree of skin reflection of the target energy rays is related to the degree of pigmentation. For example, when infrared rays with a wavelength of 0.9 μm irradiate the skin, skin without pigmentation reflects about 60% of the energy, while skin with pigmentation reflects about 40% of the energy. In addition, the metabolic activities and heat radiation generated by human cells and tissues are different when they are in different states. For example, when a tissue is in a state of chronic disease, insufficient blood supply, or local necrosis, its metabolic heat intensity is relatively low; while the metabolic heat intensity is relatively high in diseases such as pain, hyperplasia, inflammation, and tumors. Taking breast cancer cells as an example, in the early stage of the disease, the metabolic heat production of cancer cells can reach 70 mw / cm³, and the temperature difference between them and the surrounding normal cells can be more than 2°C. When skin cells are in a diseased state, they can also cause abnormal pigment metabolism and pigmentation. Therefore, based on the correlation between reflected energy, degree of pigmentation, diseased cell tissue, and cell tissue temperature, the coupling relationship between the temperature value of the medium layer in human skin and the power value of reflected energy reception can be obtained. This will ultimately construct a three-dimensional temperature image of the medium and can be used to predict the disease condition.

[0065] Therefore, the three-dimensional medium temperature identification method provided in this embodiment changes the traditional method of passively measuring temperature based on the radiation energy of the target medium (such as the radiation energy of the human body). By actively transmitting target energy lines (including infrared energy lines, laser energy lines, and radio frequency energy lines) to the target medium, and utilizing the time difference of the target energy lines in the target medium and the characteristic that the target energy lines reach different depth levels of the target medium at different times and are reflected, a preset location point is selected. The target energy lines reflected by the target medium to the preset location point at different time points are received, and the power values ​​corresponding to each time point are obtained. These multiple power values ​​can characterize the reflected energy of each depth level. Based on the coupling relationship between the reflected energy of each depth level and the current temperature of that depth level, the medium layer temperature value of each depth level is derived. Thus, a first mapping relationship between the medium depth and the current temperature value at each depth level can be established. Finally, a three-dimensional temperature image of the medium that can characterize the temperature information at each depth level of the target medium is constructed through temperature development and other technologies. The above technical solution can overcome the shortcomings of current non-contact temperature measurement devices, which can only detect the surface temperature of the target medium and can only construct a two-dimensional temperature image of the target medium. It can accurately reflect the current temperature at each depth level in a multi-layered target medium and construct a three-dimensional temperature image of the target medium, so that users can more accurately control the overall temperature of the target medium in the process of processing, production, medical testing and other processes.

[0066] Optionally, refer to Figures 1 to 3 Step S3 includes:

[0067] S31, take each first node power value as the target power value in turn, and take the first node power value that is earlier than the target power value as the base power value;

[0068] S32, by subtracting the corresponding base power value from the target power value, a dielectric layer reflection power value is obtained based on each target power value;

[0069] S33, a first dielectric layer temperature value is obtained based on the reflection power value of each dielectric layer.

[0070] Based on the principle of the three-dimensional medium temperature identification method described in the above embodiments, it can be seen that the first received power value a1 represents the reflected energy of the first depth level 11 received at the preset position point at 0.1s; the first received power value a2 represents the sum of the reflected energy of the first depth level 11 and the second depth level 12 received at the preset position point at 0.2s; and the first received power value a3 represents the sum of the reflected energy of the first depth level 11, the second depth level 12, and the third depth level 13 received at the preset position point at 0.3s. Therefore, to derive the coupling relationship between the energy of the target energy line reflected by each depth level in the target medium 1 and the current temperature of that depth level, the corresponding first received power values ​​must be used to derive the... The temperature value of the medium layer at each depth level needs to be obtained by subtracting the previously received reflected energy (i.e., the reflected energy at the depth levels through which the target energy line has already passed) from the total reflected energy received at the current time. Only in this way can the reflected energy at each depth level be accurately obtained. In other words, it is necessary to subtract the first received power value (base power value) obtained at the previous time point from each obtained first received power value (target power value). Only in this way can the medium layer reflected power value directly corresponding to the reflected energy at each depth level be obtained. Thus, the current temperature (first medium layer temperature value) of each depth level can be obtained more directly based on the coupling relationship between the energy of the target energy line reflected by each depth level in the target medium 1 and the current temperature of that depth level.

[0071] Optionally, refer to Figures 1 to 3 Step S32 includes:

[0072] S321, the current repetitive power value is obtained by multiplying the base power value by the preset conversion parameter; wherein, the preset conversion parameter is used to characterize the degree of attenuation of the target energy line in the target medium;

[0073] S322, by subtracting the corresponding current repetition power value from the target power value, a dielectric layer reflection power value is obtained based on each target power value.

[0074] Understandably, when the target energy line reaches any depth level, some of the target energy line is reflected by that depth level, some passes through that depth level and is projected to the next depth level, and some is continuously absorbed by the target medium 1 or refracted to other unreceivable angles during transmission. As time goes by, this will manifest as the attenuation of the target energy line in the target medium 1. This will result in a non-linear relationship between the total amount of target energy line received at a later time point and the target energy line received at a previous time point. In other words, the reflected energy of each depth level obtained at previous time points has changed at the current time point. The method of simply subtracting the reflected energy received at previous time points from the total reflected energy received at each time point can no longer obtain the accurate reflected energy of that depth level.

[0075] To address the aforementioned issues, this implementation introduces a preset conversion parameter. This parameter is multiplied by the reflection energy (specifically, the base power value) of each depth level obtained at previous time points, thereby converting it into the reflection energy (specifically, the current repetition power value) of the aforementioned depth levels at the current time point. Then, by subtracting the reflection energy (specifically, the current repetition power value) of the aforementioned depth levels at the current time point from the total reflection energy (specifically, the target power value) obtained at the current time point, a more accurate reflection energy (i.e., the reflection power value of the medium layer) of the corresponding depth level can be obtained, thereby improving the accuracy of the medium three-dimensional temperature image.

[0076] As an example, the reflection power value of the first depth layer 11 of the target medium 1 is a1, the reflection power value of the second depth layer 12 of the target medium 1 is a2-αa1 (α is a preset conversion parameter), and the reflection power value of the third depth layer 13 of the target medium 1 is a3-βa2-γa1 (β and γ are preset conversion parameters). Using the above local gradient calculation method, a three-dimensional temperature image of the medium that more accurately characterizes the overall temperature condition of the target medium 1 can be obtained.

[0077] Optionally, refer to Figures 1 to 3 Before step S1, the following are included:

[0078] S0, establish a correlation table between the reflected power value of the dielectric layer and the temperature value of the dielectric layer;

[0079] Step S33 includes:

[0080] S331, based on the reflection power value of each dielectric layer, look up the corresponding temperature value of the first dielectric layer in the association table.

[0081] The aforementioned association table can be pre-stored in a storage device for quick retrieval during subsequent calculations, thereby improving the construction speed of the medium's three-dimensional temperature image.

[0082] Optionally, refer to Figures 1 to 3 Before step S4, the following are included:

[0083] S041, switch the wavelength value of the target energy line and emit the target energy line into the target medium;

[0084] S042, receive the target energy line reflected by the target medium at a preset location point to obtain the corresponding second received power value, and use the second received power value at multiple preset time nodes as the second node power value;

[0085] S043, a second dielectric layer temperature value is obtained based on the power value of each second node;

[0086] Step S4 includes:

[0087] S41, based on the correspondence between the preset time node and the medium depth of the target medium, establish a second mapping relationship between the medium depth and the temperature value of the second medium layer;

[0088] S42, based on the first mapping relationship and the second mapping relationship, construct a three-dimensional temperature image of the medium.

[0089] This embodiment repeats the transmission, reception, and calculation steps of the above embodiment after changing the wavelength value of the target energy line (the specific steps can be referred to the above embodiment, which will not be repeated here) to obtain another set of temperature measurement data corresponding to the wavelength value, and then obtains a second mapping relationship based on the set of temperature measurement data; in this way, the temperature measurement data of this set can be compared and corrected with the temperature measurement data corresponding to the previous wavelength value, eliminating occasional interference factors, and a three-dimensional temperature image of the medium that can more accurately characterize the overall temperature condition of the target medium 1 can be constructed based on the first mapping relationship and the second mapping relationship.

[0090] Optionally, refer to Figures 1 to 3 Step S0 includes:

[0091] S01, establish a correlation table between the target energy line wavelength, the dielectric layer reflection power value, and the dielectric layer temperature value.

[0092] The acquired temperature measurement data may differ under different target energy line wavelength values. By pre-establishing a correlation table between the target energy line wavelength, the dielectric layer reflection power value and the dielectric layer temperature value and storing it in a storage device, it can be quickly retrieved during the calculation process to more accurately correspond to the dielectric layer temperature value under the corresponding wavelength value, thereby further improving the accuracy and construction speed of the dielectric three-dimensional temperature image.
