[0074] 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.

[0075] The embodiment of the present invention provides a ward without accompanying nursing management system based on the Internet of Things, such as Figure 1 As shown, including:

[0076] Demand perception module 1, used to perceive the nursing needs of patients in the ward based on the Internet of Things;

[0077] The nursing control module 2 is used to control the accompanying robot in the ward to provide nursing care to the patient in accordance with the nursing needs.

[0078] Multiple sensing devices are set up in the ward, and the Internet of Things is used to connect with each sensing device to sense the patient's nursing needs. Specifically, for example, the sensing device is a video camera, which captures the patient's image, analyzes the patient's image to determine whether there is an action that requires the patient to get up, and senses that the nursing need is that the patient wants to get up; another example: the sensing device is a sound pickup device, and the sound pickup device receives the patient's instruction that he wants to eat a meal, then the nursing need is that the patient wants to eat a meal. A companion robot is set up in the ward, and the companion robot can complete the work of accompanying and nursing the patient alone. When the nursing need is sensed, the companion robot in the ward is controlled to perform nursing work that meets the nursing needs.

[0079] This application is based on the Internet of Things, senses the nursing needs of patients in the ward, controls the accompanying robots in the ward to provide nursing work that meets the nursing needs of the patients, and realizes a nursing method without an accompanying system.

[0080] In one embodiment, the IoT-based ward care management system for non-escort nursing care also includes:

[0081] Plans to add modules for:

[0082] Get the future work plan of accompanying robots to provide care for patients;

[0083] Based on the work plan, determine the gap-period sequence;

[0084] Get material-time sequence;

[0085] Add the material-duration sequence as a supplementary work plan to the future work plan;

[0086] The gap-time sequence includes multiple first matching items of nursing gaps and corresponding gap time periods, a nursing gap is a gap between two consecutive plan items in the future work plan, and the gap time period corresponding to the nursing gap is a time period corresponding to the gap; the first matching items are sorted in the gap-time sequence according to the time sequence of the nursing gaps in the first matching items in the future work plan;

[0087] The material-duration sequence includes a plurality of second matching items of interactive materials and corresponding interaction durations, wherein the interactive materials are materials for interacting with the patient, and the interaction duration corresponding to the interactive materials is the duration of interacting with the patient using the interactive materials; the second matching items are sorted in the material-duration sequence according to the interaction order of the interactive materials in the second matching items;

[0088] The material-duration sequence and the gap-period sequence meet all standard applicable conditions;

[0089] The applicable conditions of the standards include:

[0090] The number of sequence items in the material-duration sequence and the gap-period sequence is the same;

[0091] The absolute value of the difference between the interaction duration in the i-th second matching item in the material-duration sequence and the duration of the gap period in the i-th first matching item in the gap-period sequence is less than a first threshold;

[0092] The interactive material in the i-th second matching item in the material-duration sequence meets the material applicability conditions of the planned items at both ends of the gap time period in the first i-th first matching items in the gap-time period sequence.

[0093] Whenever the accompanying robot is controlled to provide nursing work that meets the nursing needs of the patient, the accompanying robot will arrange its own future work plan; the future work plan will include multiple consecutive plan items, and the plan items include planned work content and planned time periods. There may be gaps between two consecutive plan items, that is, the gap time of the blank time period between the planned time periods, which is used as a nursing gap, and its corresponding gap time period is the blank time period; after determining the gap-time period sequence, the material-duration sequence is obtained, and the material-duration sequence and the gap-time period sequence meet all standard applicable conditions, so that the material-duration sequence is suitable for adding to the future work plan. After the addition is completed, the accompanying robot The corresponding interactive materials will be used to interact with the patient during the nursing breaks, making good use of the gap time; the interactive materials can be virtual animations, virtual character performances, audio and video materials, etc.; generally, when the accompanying robot is performing nursing work for the patient, the patient may feel uncomfortable or even nervous, and may also feel slightly bored and bored due to the repetitive daily nursing work. The embodiments of the present invention can solve these problems, introduce a gap-time period sequence, obtain a material-duration sequence, and add the material-duration sequence as a supplementary work plan to the future work plan, make good use of the gap time, and control the accompanying robot to interact with the patient through interactive materials, thereby enhancing the fun of accompanying and making it more humane.

[0094] In the nursing gap in the i-th first matching item, the interactive material in the i-th second matching item is used to interact with the patient; therefore, it is necessary to ensure that the number of sequence items in the material-duration sequence and the gap-period sequence is the same, and the number of sequence items is the total number of the first matching item or the second matching item; the first threshold can be 15 seconds; so that the absolute value of the difference between the interaction duration in the i-th second matching item in the material-duration sequence and the duration of the gap period in the i-th first matching item in the gap-period sequence is less than the first threshold, it can be ensured that when the interactive material in the i-th second matching item is used to interact with the patient in the nursing gap in the i-th first matching item, the complete demonstration of the interactive material is not affected as much as possible, and the execution of the planned item after the accompanying robot performs the nursing gap is not affected; the two-end planned item refers to the planned item at the two time endpoints of the gap period; the material applicable condition is that the demonstration of the interactive material is applicable to the two-end planned items, for example: if the two-end planned items are both to adjust the mattress temperature, then the material applicable condition is that the interactive material must be a prompt animation of the outdoor and indoor temperature, etc. Setting various standard applicable conditions can fully ensure the suitability, accuracy and comprehensiveness of the material-duration sequence acquisition.

[0095] In one embodiment, the IoT-based ward care management system for non-escort nursing care also includes:

[0096] Interaction control module, used to:

[0097] Monitor the patient's emotional level; the emotional level represents the health of the patient's emotional state. The higher the emotional level, the healthier the patient is. During monitoring, the patient's behavior as reflected in the monitoring video screen can be analyzed to determine his or her emotional level. The emotional level monitoring mechanism can be set up in advance by the technicians.

[0098] When the emotion level is less than the second threshold, the video playback device and the corresponding video source being viewed by the patient are obtained; the second threshold may be 5; when the emotion level is less than the second threshold, it indicates that the patient's emotional health is poor; the video playback device may be a television, etc.; the video source is the source file address of the content played by the video playback device;

[0099] Obtain the play content sequence of the video source within a preset future time; the preset future time may be 300 seconds; the play content sequence includes play contents arranged in order of play sequence;

[0100] Based on the patient's profile, multiple sets of one-to-one corresponding content screening conditions and condition weights are generated; the patient's profile includes: age, gender, occupation, medical history, hobbies, etc.; the content screening condition is to screen out the conditions that the playback content meets the patient's preferences, and the corresponding condition weight is the degree to which the playback content meets the patient's preferences if the playback content meets the content screening condition; for example: the patient's hobby is golf, then the content screening condition is the content of golf games, and the corresponding condition weight is 10;

[0101] Counting the evaluation value of each playback content in the playback content sequence; the evaluation value is the sum of the corresponding condition weights of the content screening conditions that the playback content meets;

[0102] The playback content with the maximum evaluation value is taken as the first target content; the larger the evaluation value, the more interested the patient will be in the corresponding playback content, therefore, the playback content with the maximum evaluation value, i.e., the most interesting to the patient, is taken as the first target content;

[0103] The playback content with the largest evaluation value among the preset number of playback contents before the first target content in the playback content sequence is selected as the second target content; the preset number may be the first three; the playback content with the largest evaluation value among the preset number of playback contents before the first target content in the playback content sequence is selected as the second target content, so that when the patient views the second target content, he or she will be more interested and engaged, and the probability of noticing that the accompanying robot moves its position is lower;

[0104] When the video playback device plays the second target content, the accompanying robot is controlled to position so that the accompanying robot, the patient and the video playback device meet the first relative position condition; meeting the first relative position condition makes the patient feel that the accompanying robot accompanies him to view the video playback device;

[0105] Obtain an interactive action sequence corresponding to the first target content; the interactive action sequence includes a plurality of interactive actions that are suitable for the accompanying robot to sequentially perform in response to the first target content. For example, if the first target content is a golf player swinging and scoring a goal, the interactive actions in the interactive action sequence are, in sequence, imitating a swing action, clapping to celebrate a goal, etc.;

[0106] When the video playback device plays the first target content, the position of the accompanying robot is controlled so that the accompanying robot, the patient and the video playback device meet the second relative position condition, and the accompanying robot is controlled based on the interactive action sequence. When the second relative position condition is met, the patient feels that the accompanying robot is showing himself; based on the interactive action sequence, the accompanying robot is controlled so that the patient further enhances the feeling that the accompanying robot is accompanying him to view the video playback device;

[0107] The first relative position condition includes:

[0108] The accompanying robot faces the display surface of the video playback device;

[0112] The accompanying robot faces away from the display surface of the video playback device.

[0113] Most ward patients, especially the elderly, may have fewer daily entertainment activities and often spend their time watching TV. As time goes by, the patients may become depressed. The embodiment of the present invention can solve this problem by determining the first target content and the second target content, and accurately determining the position control and action control timing of the accompanying robot, so that the patients can fully feel that the accompanying robot is accompanying them to watch the video playback device, thereby improving the fun, soothing the patients' emotions, being particularly humane, and improving the applicability of the system to the non-escort system.
