[0027] Figure 1 The present invention is a structural block diagram of a power control system of a light therapy system. DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings 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.

[0029] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0030] In this embodiment, a light therapy system power control system is provided. Figure 1 is a system block diagram of a power control system of a light therapy system according to an embodiment of the present invention. Figure 1 As shown, including:

[0031] The instruction acquisition module 11 is used to acquire a system startup instruction, and according to the system startup instruction, gradually increase the system operating power to a first power according to a preset rule, wherein the first power is greater than 100W;

[0032] In this embodiment, the magnitude of the first power is different in different usage environments. For example, some are 150W and some are 120W. This is determined according to usage requirements and the type of emitted light (such as titanium light, etc.).

[0033] Among them, gradually increasing the working power instead of directly reaching the preset power of more than 100W is to avoid burning or fluctuation of some modules of the phototherapy system during the rapid increase of power, so as to ensure the smooth operation of the system; the gradual increase method can be implemented step by step in multiple stages, for example, first increase from 5W in the power-on state to 20W at a rate of 5W / min, and then maintain the current power for 10s. In the absence of abnormal conditions (such as laser fluctuations, control module abnormalities and inability to run smoothly, etc.), increase the power from 20W to 60W at a rate of 10W / min, and then maintain the current power for 10s. Under normal operation, increase the power from 60W to 80W at a rate of 10W / min, and then increase it to more than 100W after running smoothly for 10s, and so on. It should be noted that the purpose of running for 10 seconds is to detect the emission frequency, power consumption, heat impact of the laser at the current power and whether each working module is normal, so as to avoid abnormal situations during subsequent normal use; the preset rules are the way of increasing the power to the first power, including (but not limited to) the current / voltage adjustment mode, the laser adjustment mode, the adjustment of the input power, the heat dissipation of the system, etc.; of course, the preset rules of this application are not only limited to phototherapy systems, but can also be applied to other systems. In other words, other systems involving power adjustment can use the power control system described in this application.

[0034] The power adjustment module 12 is used to obtain reflected light information and perform a power adjustment action according to the reflected light information, wherein the power adjustment action includes: adjusting the system operating power to a second power greater than 50W when the reflected light information meets a first condition.

[0035] In this embodiment, the light therapy system can adjust the power for equipment detection, such as detecting the working status of each module of the light therapy system at different powers, verification test of the maximum working status of the system, system power output stability test, etc., and of course it can also be used to act on some objects (the objects may be plants) to cause some state changes (such as the growth status of plants, etc.); in the working process of the light therapy system being used to irradiate the object to cause a state change, the emitted light will produce a certain degree of reflected light after acting on the object. These reflected lights will have different distributions and parameters (such as intensity, wavelength, etc.) under different action states. Therefore, by observing the changes in these parameters and distributions, the action results can be judged, and then the light therapy system can be reacted according to the judgment results, so that the light therapy system automatically adjusts the power to achieve efficient and precise action.

[0036] The reflected light information includes (but is not limited to) parameters such as the intensity, wavelength distribution, spatial distribution, and energy intensity of the reflected light; if the reflected light information meets the preset first condition (for example, the reflected light intensity reaches a certain threshold, indicating that the tissue has fully responded to the light therapy), the system's operating power is adjusted to the second power level. The second power level is set to be greater than 50W, because the power of about 50W can make some objects of action change in another direction; it should be noted that before the power adjustment is performed, the power adjustment step length needs to be measured with a laser power meter to ensure that the power adjustment step length is executed according to the predetermined rules; the first condition includes whether the reflected light information reaches the predetermined intensity, uniformity, density, etc.

[0037] It should be noted that in addition to adjusting the power, parameters such as irradiance (power density), irradiation time (pulse width in pulsed laser), repetition frequency and pulse delay can also be adjusted.

[0038] When it is specifically applied to plant growth control, the power can be adjusted to control the growth status of the plant at different stages. For example, adjusting the light during the heading period of rice can make the heading slower or faster, etc.; and when applied to the prostate, the use of the laser can be adjusted by adjusting the power, thereby alleviating the urinary waiting, urgency, frequent urination, frequent nocturia, weak urination, dribbling urine, difficulty urinating, etc. caused by prostate hyperplasia, without limitation here.

[0039] In addition, different laser technologies (such as green laser, holmium laser, etc.) have different characteristics, and users will choose the appropriate laser type and power according to actual needs.

[0040] It should be noted that the purpose of the present invention is mainly to accurately control the power of the phototherapy system and does not involve the actual use of the phototherapy system; that is, the present invention is an improvement on the power control system of the phototherapy system, rather than an improvement on the use of the phototherapy system. For example, when the phototherapy system is used to promote plant growth, the power control system of the present invention is also applicable.

[0041] Through the above steps, the reflected light is detected, and the changes in the object of action are judged according to the detection results of the reflected light. Based on this, the working power of the system is adjusted to ensure that the working results of the system meet the requirements, thereby solving the erroneous results caused by untimely power control and improving the power control accuracy and efficiency of the system.

[0042] In an optional embodiment, when the reflected light information meets the first condition, adjusting the system operating power to the second power includes:

[0043] Determining reflected light distribution information according to the reflected light information;

[0044] When the reflected light distribution information meets a second condition, the system operating power is adjusted to the second power, wherein the first condition includes the second condition.

[0045] In this embodiment, when determining the reflected light distribution information, it is necessary to pre-separate areas with higher light intensity, calculate the uniformity of light distribution, and classify possible blind spots of light illumination, so as to ensure that the reflected light information can adequately reflect the actual changes of the object.

[0046] For example, the reflected light information can be classified according to type, energy intensity, wavelength, etc., and then divided according to the receiving area of ​​the reflected light to obtain a high-weight reflected light area, a medium-weight reflected light area, and a light-weight reflected light area. The distribution value of the reflected light in each area is calculated based on the classification result of the reflected light information and the area division result, and the distribution value is used as one of the distribution information, and the distribution result is mapped with the tissue change of the corresponding object of action, so as to establish the association between the reflected light situation and the tissue change situation; it should be noted that when making conditional judgments on the distribution information, it is possible to consider calculating the distribution results of each area in a matrix or pixel manner, such as calculating the correlation value between the matrix corresponding to the energy intensity and the matrix corresponding to the wavelength, or calculating the probability value of the image composed of pixel points through the softmax function of the neural network, and judging whether the distribution is reasonable through the probability value (for example, if the probability value is within the preset range, it is determined to meet the conditions), wherein the probability value of the image composed of pixel points calculated by the softmax function of the neural network specifically includes the following process:

[0047] First, the receiving area of ​​the reflected light is divided into regions according to a preset region division result, for example, into a nine-square grid or multiple regions;

[0048] Then, the energy intensity and other parameters of the reflected light received by each area are normalized to obtain a normalized value, and the normalized value is used as the grayscale value of the pixel point corresponding to the area. At this time, all the receiving areas of the reflected light together form a grayscale image composed of pixels;

[0049] The grayscale image is then input into a pre-trained neural network, and the probability value of the image is calculated through the softmax function of the neural network, and the output probability value calculation result is used as the rationality judgment value of the image; when the probability value is within the preset range, the image is judged to meet the requirements, otherwise it is considered that the image does not meet the requirements.

[0050] It should be noted that the softmax function is an activation function widely used in machine learning and deep learning. Its function is to convert a real number vector into a probability distribution so that each element in the vector is between 0 and 1, and the sum of all elements is 1. This makes the softmax function very suitable for use in the output layer to represent the model's predicted probability for a certain category.

[0051] In addition, judgment can also be made in other ways; among which, the receiving area of ​​reflected light can be divided according to historical data or actual experimental results; the reflected light distribution information can represent the intensity of reflected light, or the density in each area, etc. This is because different objects react differently to different lights, and the corresponding reflected light information in different areas is also different, so it is necessary to judge the change of the corresponding object through the distribution result; correspondingly, the second condition includes the uniformity of reflected light, whether the light intensity in a specific area reaches a predetermined value, etc.

[0052] In an optional embodiment, determining the reflected light distribution information according to the reflected light information includes:

[0053] Performing encoding conversion on the information set of the reflected light information to generate encoded data;

[0054] The reflected light distribution information is determined according to the coded data.

[0055] In this embodiment, in order to facilitate the calculation of the reflected light information, the reflected light collected in each area needs to be encoded; for example, the reflected light is first filtered, and then the wavelength, energy intensity, and density of each area are encoded in hexadecimal (for example, encoded as [A1#S3#F15#C5], representing A1 area, reflected light type S3, energy intensity F15, wavelength C5, and so on), and then separated according to the encoding results, and identification calculations are performed separately.

[0056] In an optional embodiment, when the reflected light information meets the first condition, adjusting the system operating power to the second power includes:

[0057] Determining the intensity of the reflected light according to the reflected light information;

[0058] When the reflected light intensity meets a third condition, the system operating power is adjusted to the second power, wherein the first condition includes the third condition.

[0059] In this embodiment, the reflected light intensity is determined in order to determine the degree of influence of the illumination on the object, thereby providing a parameter reference for power adjustment.

[0060] The third condition may be whether the intensity of reflected light in a certain area is greater than a certain threshold.

[0061] In an optional embodiment, the system further includes:

[0062] A temperature information acquisition module 13, used for acquiring temperature information of an area corresponding to the reflected light after acquiring the reflected light information;

[0063] The second power adjustment module 14 is used to adjust the system operating power to the second power when the temperature information meets the fourth condition and the radiation light information meets the first condition.

[0064] In this embodiment, during actual use, continuous laser irradiation of the object will inevitably cause temperature changes in the area, and the object will react differently to different temperature changes under different changing states. Therefore, the temperature needs to be observed to avoid excessive temperature caused by continuous action and to ensure that the action results meet the requirements.

[0065] Among them, the fourth condition includes whether the temperature value of a certain area reaches a preset temperature threshold, or whether the temperature value of the entire action area reaches a preset temperature threshold, etc.; it should be noted that in addition to observing the reflected light and temperature, power adjustment can also be performed in other ways; for example, observing the relationship between the inductance / voltage / current of the laser transmitter of the phototherapy system to determine whether the power during operation meets the requirements. Specifically, first obtain the backlight power, then convert the backlight power into an electrical signal, and then compare the electrical signal with the reference voltage through a comparator, and determine whether the adjusted power meets the requirements based on the comparison result, and adjust the driving current of the laser based on this so that the working power of the phototherapy system meets the requirements; or by collecting images of the action area of ​​the phototherapy system, the image is identified to determine the color change of the skin caused by the photosensitizer in the image. This is because photosensitizers are usually required to be applied during the action process to increase Strong effect, for example, Xibofen (hematoporphyrin injection) as a photosensitizer for tumor photodynamic therapy (PDT), targeted accumulation in tumor tissue through lipid pathways, and photochemical reaction occurs under laser irradiation of a specific wavelength, producing cytotoxic reactive oxygen species, precisely destroying tumor cells, or photosensitizers are excited to transition to an excited state under irradiation of a light source of a specific wavelength, producing reactive oxygen species (ROS) with biological toxicity. These ROS will affect proteins, fats and other molecules in the photosensitive area, and may also cause changes in skin color, such as pigmentation or color fading. The uniformity of the photosensitizer directly affects the uniformity of this color change. Therefore, by observing the color change of the skin, it can be judged whether the effect of the laser on the area meets the requirements, and then the working power of the light therapy system is adjusted according to the different skin color changes, so that the effect on each area meets the preset requirements, and so on.
