Description

Technical Field

[0001] The present invention relates to the technical field of wireless charging of cardiac pacemakers, and in particular to a distance adaptive wireless charging system based on in vivo microwave response. Background Art

[0002] Currently, in order to avoid unnecessary removal of the pacemaker from the patient's body for charging purposes, wireless charging methods that do not require surgical removal are often used to charge the pacemaker.

[0003] However, wireless charging requires that the distance between the wireless charging device and the charging object is close enough. However, due to the special location of the pacemaker implanted in the patient's body, the patient needs to deliberately put his heart close to the wireless charging device, and maintain the posture continuously before the wireless charging is completed. This will result in a poor experience every time the pacemaker is wirelessly charged, and in the long run, it may also affect the patient's mood.

[0004] Therefore, a solution is urgently needed. Summary of the invention

[0085] The technical solution of the present invention is further described in detail below through the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0086] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0089] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0090] The embodiment of the present invention provides a distance adaptive wireless charging system based on in vivo microwave response, such as Figure 1 As shown, including:

[0091] The reminder module 1 is used to remind the patient to charge when it is detected that the power of the patient's pacemaker is low;

[0092] A first control module 2, used to control the wireless charging device to measure the distance between the wireless charging device and the pacemaker based on the microwave response of the pacemaker in the patient's body;

[0093] The second control module 3 is used to control the wireless charging device to charge the pacemaker when the distance meets the wireless charging condition;

[0094] The third control module 4 is used to control the wireless charging device to perform charging interaction with the patient when the wireless charging device is charging the pacemaker.

[0095] When measuring the distance between the wireless charging device and the pacemaker, the wireless charging device transmits a signal to the pacemaker, the pacemaker responds and generates a reflected signal, and the distance strategy is performed by combining the transmitted signal and the reflected signal. Wireless ranging belongs to the scope of existing technology and will not be traced back. The wireless charging condition can be less than or equal to the distance threshold. When the distance is less than or equal to the distance threshold, the wireless charging device is controlled to charge the pacemaker. When the wireless charging device is charging the pacemaker, the wireless charging device is controlled to interact with the patient for charging.

[0096] This application is particularly applicable because when the wireless charging device is charging a pacemaker, it controls the wireless charging device to interact with the patient in charging, thereby improving the patient's experience in wireless charging of the pacemaker and avoiding the patient's need to deliberately maintain a posture for a long time to wirelessly charge the pacemaker, which may affect his or her emotions.

[0097] In one embodiment, when the wireless charging device is charging the pacemaker, the third control module controls the wireless charging device to perform charging interaction with the patient, including:

[0098] Control the wireless charging device to monitor the patient's multimodal information; the multimodal information includes: the patient's body movement information, conversation information with others, content browsed on the mobile phone, etc.;

[0099] Based on the intention prediction knowledge base, multiple behavioral intentions and corresponding intention probabilities are determined according to multimodal information. The intention prediction knowledge base contains a large amount of intention prediction knowledge, which is used to predict the patient's behavioral intention and corresponding intention probability according to multimodal information. The behavioral intention refers to what the patient wants to do next, and the intention probability is the probability that the patient wants to do the thing next. For example, the intention prediction knowledge outputs that when the patient browses the video APP, his behavioral intention is to watch a movie, and the corresponding intention probability is 60%. The intention prediction knowledge can be set by the technician according to actual needs.

[0100] When the maximum intention probability is less than or equal to the probability threshold, the wireless charging device is controlled to obtain the patient's charging posture; the probability threshold may be, for example, 35%; when the maximum intention probability is less than or equal to the probability threshold, it means that the patient does not have a sufficiently clear behavioral intention, and charging interaction is most needed at this time; the charging posture is the patient's body posture at this time, and the wireless charging device may have a built-in millimeter wave radar sensor to obtain the charging posture;

[0101] Determine the standby interactive device based on the charging posture, the device location of the wireless charging device and the smart home map of the patient's environment; the standby interactive device is a smart home device in the patient's environment that can be used to control the patient to perform charging interaction;

[0102] Based on the charging interaction mode library, multiple charging interaction modes are determined according to the supported configuration information of the device to be interacted; the supported configuration information of the device to be interacted is the functional configuration of the device to be interacted, such as: supporting music playing, supporting video playing, etc.; the charging interaction mode library has charging interaction modes corresponding to different supported configuration information, for example: the supported configuration information of the device to be interacted reflects that each device to be interacted supports music playing, then the charging interaction mode has music linkage playback through each device to be interacted, so as to achieve the effect of simulating a concert;

[0103] Calculate the evaluation value of each charging interaction mode, the calculation formula is as follows:

[0104]

[0105] Among them, Eva is the evaluation value of the charging interaction mode, K i,j is the relationship weight of the jth association between the ith behavioral intention and the charging interaction mode, n i is the total number of associations between the ith behavioral intention and the charging interaction mode, P iis the intention probability corresponding to the ith behavior intention, and m is the total number of behavior intentions; there is a correlation between the behavior intention and the charging interaction mode, for example: the interaction behavior generated after the charging interaction mode is executed is consistent with the behavior intention, etc.; the correlation relationship is preset with a relationship weight, and the larger the relationship weight, the more suitable the charging interaction mode is for the behavior intention;

[0106] Based on the charging interaction mode with the maximum evaluation value, the standby interactive device is controlled to perform charging interaction with the patient. The larger the evaluation value, the more suitable the corresponding charging interaction mode is. Based on the charging interaction mode with the maximum evaluation value, the standby interactive device is controlled to perform charging interaction with the patient.

[0107] When the present application controls the wireless charging device to interact with the patient for charging, it first determines whether the patient has a clear behavioral intention. When the patient does not have the clear behavioral intention, the charging interaction control is performed to avoid disturbance and influence caused by the charging interaction control of the patient having a clear behavioral intention, which is more humane and intelligent. In addition, it connects with the smart home in the patient's environment and controls the smart home to interact with the patient for charging, thereby improving the applicability of the system. Secondly, the evaluation value of each charging interaction mode is quickly calculated through the above calculation formula, and the charging interaction mode with the maximum evaluation value is selected to control the standby interactive device to interact with the patient for charging, thereby improving the suitability and control efficiency of the charging interaction control.

[0108] In one embodiment, the step of determining the interactive device to be used based on the charging posture, the device location of the wireless charging device, and the smart home map of the patient's environment includes:

[0109] Get the target posture;

[0110] Based on the audio-visual area determination template, in the smart home map, the audio-visual area of ​​the patient in the environment is determined according to the target posture and the device position of the wireless charging device; the audio-visual area determination template refers to taking the visible area of ​​the patient represented by the target posture within a preset radius (for example, within a radius of 8 meters) around the device position of the wireless charging device in the smart home map as the audio-visual area;

[0111] The intelligent audio-visual devices falling into the audio-visual area are used as standby interactive devices;

[0112] Among them, obtaining the target posture includes:

[0113] Obtaining the retention rate of the charging posture; the retention rate is the probability that the patient will maintain the charging posture within a certain period of time (e.g., 10 minutes) in the future; the corresponding retention rate can be determined in advance according to the comfort level of different patients in maintaining wireless charging of the pacemaker; the greater the comfort level of the charging posture, the greater the retention rate;

[0114] When the persistence rate is greater than or equal to the retention rate threshold, the charging posture is taken as the target posture; the retention rate threshold may be, for example, 75%; when the persistence rate is greater than or equal to the retention rate threshold, it indicates that the probability of the patient maintaining the charging posture for a certain period of time in the future is relatively high, and the charging posture is taken as the target posture;

[0115] When the persistence rate is less than the retention rate threshold, the charging posture is predicted to be maintained in the future and used as the target posture. When the persistence rate is less than the retention rate threshold, it means that the probability of the patient maintaining the charging posture for a certain period of time in the future is low, and the charging posture is predicted to be maintained in the future and used as the target posture; when predicting the charging posture to be maintained in the future, the prediction can be made based on the patient's historical body posture.

[0116] The embodiment of the present invention reasonably determines the target posture when determining the interactive device to be used, thereby improving the rationality of determining the audio-visual area.

[0117] In one embodiment, after the third control module controls the standby interactive device to perform charging interaction with the patient based on the charging interaction mode with the maximum evaluation value, it further includes:

[0118] Control the wireless charging device to monitor the patient's interactive response information; the interactive response information may be the patient's behavioral actions, speech content, etc. after receiving the charging interaction;

[0119] Based on the interaction response information, the degree value of the patient's involvement in the charging interaction with the standby interactive device is determined; based on the interaction response information, the degree value of the patient's involvement in the charging interaction with the standby interactive device can be determined, and the degree value reflects the degree to which the patient accepts the charging interaction. For example, if the interaction response information reflects that the patient enjoys the effect of the simulated concert achieved by the combined audio playback of the standby interactive devices (for example, the action of waving to the rhythm), the corresponding degree value is relatively large;

[0120] When the degree value is less than or equal to the degree value threshold, the charging interaction mode based on the maximum evaluation value is obtained, and the first mode control progress of the standby interactive device for charging interaction with the patient is controlled. At the same time, the charging interaction mode with a non-maximum evaluation value and an evaluation value greater than or equal to the evaluation value threshold is determined and used as the target charging interaction mode; the degree value threshold can be, for example, 8; the evaluation value threshold can be, for example, 10; when the degree value is less than or equal to the degree value threshold, it means that the patient's acceptance of charging interaction is small, the first mode control progress is obtained, and the target charging interaction mode is determined;

[0121] Determine a second mode control progress that can take over the first mode control progress from the target charging interaction mode;

[0122] Starting from the second mode control progress, based on the target charging interaction mode, the standby interactive device is controlled to perform charging interaction with the patient.

[0123] After the embodiment of the present invention controls the standby interactive device to perform charging interaction with the patient, the patient's response is determined, and whether the interactive control needs to be changed according to the response. If so, the target charging interaction mode and the second mode control progress are determined. Starting from the second mode control progress, based on the target charging interaction mode, the standby interactive device is controlled to perform charging interaction with the patient, which greatly improves the rationality and applicability of the interactive control.

[0124] In one embodiment, determining the second mode control progress that can take over the first mode control progress from the target charging interaction mode includes:

[0125] Parsing a control progress sequence of a target charging interaction mode; the control progress sequence includes control progresses generated in sequence after executing the target charging interaction mode;

[0126] Based on the non-relay connection control progress determination template, the non-relay connection control progress is determined from the control progress sequence; the non-relay connection control progress determination template is to determine the control progress that is obviously not capable of relay interaction and is cut in from the control progress sequence, that is, the non-relay connection control progress, for example: prompting the patient to rest on his own (it cannot be directly cut in to prompt the patient to rest);

[0127] Based on the progress cluster screening condition, a progress cluster including at least one non-relay connection control progress is screened out from the control progress sequence; the progress cluster screening condition includes: combining continuous non-relay connection control progresses to form a progress cluster;

[0128] Based on the template for determining the control schedule to be selected, the control schedule to be selected is determined from the control schedule sequence; the template for determining the control schedule to be selected is that if the number of control schedules between the two schedule clusters exceeds a threshold value (for example, 3), the first control schedule among the control schedules between the two schedule clusters is used as the control schedule to be selected (if the first control schedule is selected and there are multiple control schedules to be executed, it means that the selection is appropriate);

[0129] Obtaining a suitable value of the control schedule to be selected; the suitable value represents the degree of adaptation between the control content before switching into the control schedule of the first mode in the charging interaction mode with the maximum evaluation value;

[0130] Taking the candidate control schedule with the maximum suitable value as the second mode control schedule;

[0131] The obtaining of a suitable value of the control progress to be selected includes:

[0132] The control content after the selected control progress in the target charging interaction mode and the control content before the first mode control progress in the charging interaction mode with the maximum evaluation value are characterized to obtain a characteristic description vector; the control content may be the type of music played, the rhythm of the music played, etc.; the control content after the selected control progress in the target charging interaction mode and the control content before the first mode control progress in the charging interaction mode with the maximum evaluation value are characterized to construct a characteristic description vector in the form of a vector;

[0133] The appropriate value corresponding to the feature description vector is determined from the appropriate value library. The appropriate value library contains appropriate values ​​corresponding to different feature description vectors. The larger the appropriate value, the greater the appropriateness of the candidate control schedule reflected by the feature description vector.

[0134] When determining the second mode control progress that can relay the first mode control progress from the target charging interaction mode, the embodiment of the present invention introduces a progress cluster screening condition and a template for determining the candidate control progress, quickly determines the candidate control progress for further evaluation, and then introduces a suitable value, and uses the candidate control progress with the maximum suitable value as the second mode control progress, thereby improving the accuracy, suitability and determination efficiency of the second mode control progress.
