Description

[Technical field]

[0001] The present invention belongs to the technical field of skin treatment instruments, and in particular to a control system and a control method of an ultraviolet light therapy instrument based on distributed sensing. [Background technology]

[0002] Ultraviolet light therapy is a medical device that uses ultraviolet radiation to treat skin diseases. It stimulates the metabolic activity of skin cells and enhances immunity by irradiating ultraviolet light of a specific wavelength onto the skin surface, thereby achieving the effect of treating skin diseases.

[0003] In order to improve the safety of using ultraviolet light therapy devices, patent CN219896806U in the prior art discloses a light therapy device with a safety device, which has a contact induction coil arranged around the light outlet, and controls the light output by detecting whether there is contact with the patient's skin through the contact induction coil, thereby achieving the purpose of safety control; however, the light therapy device is only suitable for the treatment of skin in patient areas with high flatness, and is not suitable for areas with obvious concave and convex features, small curved surface areas, or patient areas at some edge positions, such as fingers, toes, cheek and jaw edges, etc. When the light outlet of the light therapy device cannot fully fit the skin, but can only partially fit the skin, if the above-mentioned light therapy device is used for treatment, the light output will stop or will not be emitted because the light outlet does not fully fit the skin, resulting in the treatment process being often interrupted or even unable to perform light therapy normally.

[0004] Therefore, it is necessary to provide a new ultraviolet light therapy device control system and control method based on distributed sensing to solve the above technical problems. [Summary of the invention]

[0005] The main purpose of the present invention is to provide a control method for an ultraviolet light therapy device based on distributed sensing, which takes the particularity of the patient's location into consideration to perform safe control of skin fitting, thereby improving the treatment smoothness and use stability of the light therapy device while ensuring safety.

[0006] The present invention achieves the above-mentioned purpose through the following technical scheme: a distributed sensing-based ultraviolet light therapy device control system, which includes:

[0007] A light emitting module, used for emitting ultraviolet light;

[0008] Skin sensing modules, the number of which is P and which are spaced around the light outlet of the phototherapy device, where P is an integer greater than or equal to 2;

[0009] The main control unit is electrically connected to the light-emitting module and the skin sensing module; when the number of skin sensing modules detected to be in contact with the skin reaches a set number A, the main control unit controls the light-emitting module to emit light, where A is less than or equal to P.

[0010] Furthermore, it also includes a parameter setting module electrically connected to the main control unit, which is used to collect the user's parameter setting information, and the parameter setting information includes the setting of the safety control mode; the safety control mode includes a full control mode and a non-full control mode; the full control mode is when the set number A is equal to the number P of skin sensing modules; the non-full control mode is when the set number A is less than the number P of skin sensing modules

[0011] Furthermore, the skin sensing modules are distributed around the light outlet of the phototherapy device to form a plurality of monitoring points or monitoring areas.

[0013] Furthermore, it also includes a communication module and control software installed on a mobile terminal, the main control unit is connected to the mobile terminal signal through the communication module, and the control software is provided with the parameter setting module.

[0014] Furthermore, the parameter setting information also includes luminous intensity and lighting duration.

[0015] Another object of the present invention is to provide a control method based on the ultraviolet light therapy device control system as described above, comprising the following steps:

[0016] S101, set the initial value of i to 1, the initial value of j to 0, and obtain the set number A and the number P of skin sensing modules;

[0017] S102, digitizing the induced skin signal i collected by the i-th skin sensing module, i=1, 2, ..., P;

[0018] S103, determining whether the value of the induced skin signal i exceeds a set threshold, if so, the skin contact count is j++; otherwise, executing the next step; the set threshold is the value of the induced skin signal i collected by the skin sensing module after being digitized when the skin is in contact with the skin;

[0019] S104, determine whether i is less than P, if so, then i++ and return to step S102; if not, proceed to the next step;

[0020] S105 , determining whether the value j is greater than or equal to A, if so, controlling the light emitting module to emit light, otherwise controlling the light emitting module not to emit light.

[0021] Another object of the present invention is to provide a control method based on the ultraviolet light therapy device control system as described above, comprising the following steps:

[0022] S201, obtaining a set number A and a number P of skin sensing modules;

[0023] S202, determine whether the set quantity A is equal to P, if so, execute step S203; if not, execute step S207;

[0024] S203, set the initial value of i to 1;

[0025] S204, digitizing the induced skin signal i collected by the i-th skin sensing module, i=1, 2, ..., P;

[0026] S205, determining whether the value of the induced skin signal i exceeds a set threshold value, if so, it indicates that the skin is in close contact, and then executing step S206, if not, it indicates that the skin is not in close contact, and then executing step S212; the set threshold value is the digitized value of the induced skin signal i collected by the skin sensing module when the skin is in close contact;

[0027] S206, determine whether i is less than P, if so, then i++ and return to step S204; if not, execute step S213;

[0028] S207, set the initial value of i to 1, and the initial value of j to 0;

[0033] S212, controlling the light-emitting module to emit no light;

[0034] S213, controlling the light-emitting module to emit light.

[0035] Compared with the prior art, the beneficial effects of the control system and control method of an ultraviolet phototherapy device based on distributed sensing of the present invention are: a plurality of skin sensing modules are arranged at intervals around the light outlet of the phototherapy device to form a distributed skin fit status monitoring system. Based on the distributed skin fit monitoring system, users can set a variety of safety control modes. When the patient's affected area is located in a relatively flat large skin area, in order to improve safety, the full control mode can be turned on. In this mode, the light-emitting module will only emit light when all the sensing modules detect skin fit; if the patient's affected area is in a special position and cannot be completely fitted around the light outlet, the non-full control mode can be turned on. In this mode, the light-emitting module will only emit light when one or a set number of sensing modules detects skin fit, making the phototherapy device of this scheme suitable for more usage scenarios; the control system takes the particularity of the patient's position into consideration, and performs safety control of light output based on the flexibility of the skin fit status, thereby improving the treatment smoothness, usage stability and flexibility of the phototherapy device while ensuring safety.

[0043] Embodiment 1:

[0044] Please refer to Figure 1-Figure 4 The present embodiment is a distributed sensing-based ultraviolet light therapy device control system 100, which includes a main control unit 1, a light emitting module 2 electrically connected to the main control unit 1, at least two skin sensing modules 3 and a parameter setting module 4; the skin sensing modules 3 are arranged at intervals around the light outlet 200 of the light therapy device, and the number of the skin sensing modules is two or more.

[0045] The skin sensing modules 3 are distributed around the light outlet 200 of the phototherapy device. The skin sensing modules 3 can be distributed in a point-like manner or in a number of independent blocks to form a number of monitoring points or monitoring areas to monitor whether each monitoring position of the light outlet 200 of the phototherapy device is in contact with the skin.

[0046] The skin sensing module 3 is a capacitive sensor. When the user puts the light outlet of the phototherapy device close to the skin, the capacitance of the skin sensing module 3 will change, thereby sensing the skin contact.

[0047] The parameter setting module 4 is used to collect the user's parameter setting information, and the parameter setting information includes luminous intensity, lighting duration, and safety control mode.

[0048] The main control unit 1 controls the light emitting module 2 to emit light according to the parameter setting information and the skin fitting condition collected by the skin sensing module 3 .

[0049] The safety control modes include the following two:

[0050] (1) Full control mode: In this mode, the light-emitting module 2 will emit light only when all skin sensing modules 3 detect skin contact;

[0051] (2) Non-full control mode: In this mode, the light-emitting module 2 emits light only when the number of skin sensing modules 3 detecting skin contact reaches a set number or a set ratio.

[0052] The parameter setting module 4 can be directly integrated in the ultraviolet light therapy device control system, or it can be set in the control software of the mobile terminal. If it is set in the control software of the mobile terminal, the ultraviolet light therapy device control system 100 based on distributed sensing also includes a communication module 5, which is connected to the mobile terminal through the communication module 5. The user can set the parameter setting information in the control software installed on the mobile terminal, and then transmit it to the main control unit 1 through the communication module 5. If the user sets a non-full control mode, the number A of skin sensing modules 3 that are required to detect skin contact can also be set, and A is less than or equal to the total number P of skin sensing modules 3.

[0053] This embodiment also provides a control method for an ultraviolet light therapy device control system based on distributed sensing, which includes controlling the light output of the light emitting module 2 according to the safety control mode and the collected signals of several skin sensing modules 3.

[0055] S101, set the initial value of i to 1, the initial value of j to 0, and obtain the set number A and the number P of skin sensing modules;

[0056] S102, digitizing the induced skin signal i collected by the i-th skin sensing module 3, i=1, 2, ... P, P is the number of skin sensing modules 3, P is greater than or equal to 2;

[0057] S103, determining whether the value of the induced skin signal i exceeds the set threshold, if so, the skin contact count is j++; otherwise, executing the next step;

[0058] S104, determine whether i is less than P, if so, then i++ and return to step S102; if not, proceed to the next step;

[0059] S105 , determining whether the value j is greater than or equal to A, if so, the main control unit 1 controls the light emitting module 2 to emit light, otherwise, the light emitting module 2 does not emit light.
