Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

As shown in fig. 1 and 2, the intelligent nursing alarm system for home care comprises: the RFID tags are independently configured for each aged person needing to be nursed in the community, and each RFID tag records the unique identification of each aged person; the RFID reader is arranged at a set position in the home of a user and is used for reading the RFIF label in a reading range; the data processing module is used for collecting the reading time of the RFID tag by the RFID reader in the user' S home within a set time period, calculating the time difference between two adjacent reading times and forming a first data set S (t) by taking the natural day as a unit₁，t₂、t₃……t_n) Calculating a first data set S (t)₁，t₂、t₃……t_n) And calculating an alarm reference value by the following formula:

SOS₂(t) n-n' formula two

Wherein the SOS₁(t) is a first alarm reference value; SOS₂(t) is a second alarm reference value; n is the data quantity in the first data set at the same day and is more than or equal to 2; n' is the data quantity in the first data set of the last natural day and is more than or equal to 2; e' (t) is the first data set S (t) of the last natural day₁，t₂、t₃……t_n) Average value of (a).

The system also comprises an alarm module, and in each natural day, when the set time period is over, the comprehensive parameters are calculated according to the following formula:

X＝a*SOS₁(t)+b*SOS₂(t) formula III

Wherein a and b are adjustment coefficients specifically set according to the condition of each elderly person, preferably both positive numbers, for adjusting SOS₁(t) and SOS₂(t) weights in the synthesis parameters, wherein SOS₁The calculation of (t) adopts the basic idea of variance, and is used for evaluating the deviation degree of each data of the current day relative to the average value of the corresponding data of the previous day, so that the change of the old to be nursed in two days is judged, the updating and comparison of the data day by day ensures the accuracy of the evaluation, and the parameter reflects the action efficiency of the old to a certain extent; SOS₂The calculation of (t) adopts the basic idea of difference, and the parameter reflects the times of actions of the old to a certain extent.

the system also comprises a network module which synchronizes the community network environment, records mutual aid data at least comprising unique identification and alarm information, and forms new blocks of the mutual aid data into a block chain.

In the invention, in order to accurately identify the behaviors of the old people, the RFID tags are used as a distinguishing carrier of the old people in the system and can be worn at the remarkable position on the old people, the specific embodiment form can be any one of a card form, a badge form or a bracelet, and the like, but the number of the RFID tags is ensured to be 1, so that the influence of repeated data reading of more than two RFID tags on subsequent data processing is avoided. In the invention, the number of the RFID readers can be 1 or more, the RFID readers are distributed at different positions in the home, more accurate behavior acquisition can be realized, but different reading ranges are covered, and repeated reading of data is avoided, but the RFID readers are preferably arranged in a range with relatively high activity frequency, so that the acquisition amount of the data is guaranteed, for example, in a kitchen, a toilet or a bedroom, and the like; aiming at the old people who are sick and lie in bed, the RFID tag can be arranged on the moving part of the body and can be identified through the moving behavior of the moving part.

In the invention, the selection of the collection set time period is similar to the setting principle of the RFID reader, and the time period with higher activity frequency is selected, so that the collection amount of data, such as the morning, noon and evening meal time periods, is ensured. The selection of the set time period is as follows:

the time period is set to be a continuous time period, the time period is shorter than 1 hour, and the control of the time period is mainly used for ensuring the effectiveness of calculating the comprehensive parameters when the set time period is finished, namely the time for controlling the problem to be found is controlled, the time period shorter than 1 hour is used as the time period for finding the problem, so that the comprehensive parameters have higher effectiveness, the problem can be quickly processed, the danger caused by untimely processing of the elderly due to the emergency situation is avoided, the situation is suitable for the elderly with relatively weak physical conditions, in terms of statistics, the life habits of the elderly in the situation are more fixed, and the change of the life mode is smaller.

Another way to set the time period selection is: the set time period comprises at least two periods of time which are arranged at intervals, and the first data set S (t)₁，t₂、t₃……t_n) The data in (1) is a set of time differences between two reading times in each period of time, taking the example of collecting 4 time points in the first period of time and collecting 5 time points in the second period of time, 3 time difference values are obtained in the first period of time, and 4 time differences are obtained in the second period of timeThe difference, and therefore, 7 data were obtained for the entire first data set. The method is more suitable for the old with relatively good physical quality, and the old with the condition has certain fluctuation of living habits in daily life in view of activity flexibility, so that the method is more suitable for more distributed data acquisition time periods, and the accuracy of data processing results is ensured. In this embodiment, it is still preferable that the duration of each period of time is less than 1 hour, so as to ensure the data concentration; in addition, the time lengths of all the time periods in the set time period are preferably guaranteed to be equal, so that the centralized influence of the individual time periods on the final data processing result is avoided, and the evaluation of the data deviates from the objectivity.

The intelligent home-based care alarm system comprises a first user, a second user, a third user and an intelligent management terminal, wherein the first user is a first user, the second user is a second user, the third user is a third user, the first user is a first user, the second user is a third user, the third user is a third user, the first user is a first user, the third user is a second user, the fourth user is a third user, the third user is a third user, and the third user is a third user; the data encryption module receives and encrypts the operation information and forms unique key data for decryption; the data processing module receives the encrypted operation information and the encrypted key data, transmits the encrypted operation information to the resident service terminal of the first user, and transmits the encrypted key data to the resident service terminals of the second user and the third user; the execution module generates feedback information by decrypting the encrypted operation information through the key data in the first user home, and the data processing module is also used for calculating the time difference t from the generation of the operation information to the generation of the feedback information in the first user home_x(ii) a When t is_xAnd when the value is larger than the set value, the alarm module generates alarm information.

In the preferred scheme, when a certain old man makes a mutual help request as a first user, operation information is formed by operating through a resident service terminal, the behavior is regarded as active alarm behavior, but the processing of the alarm behavior is preferably finished in the mutual help range of a community without an external medical service system, wherein the operation can be realized through various forms such as a key or a touch screen, the operation information is obtained through conversion of a pressure signal, a temperature signal and the like, confirmation is required through other second users and third users in the community after the information is formed, the confirmation form can be regarded as the acceptance of tasks, wherein in view of the fact that mutual help groups belong to the same community, directional transmission is not carried out aiming at set personnel, a centralized management mode can be avoided, meanwhile, because the old man needing mutual help is large in age, when the second user and the third user are set, the designated person is also taken as a mutual object, and therefore, it is difficult to ensure timely and effective problem handling, so the second user and the third user in this embodiment are two users who voluntarily undertake mutual tasks after receiving information in the community, and certainly, each user will receive information for making a mutual request.

In this embodiment, the data encryption and the decryption of the second user and the third user who obtain the key data in the first user who makes the mutual assistance request are used as the basis for the mutual assistance personnel to arrive at the request site, and after the decryption, feedback information is generated, so that the default mutual assistance behavior is ended. The operation information and the feedback information are written into the block chain, all users in the community can obtain timely information synchronization, data loss and damage caused by centralized management are avoided, and the efficiency and the accuracy of information transmission are guaranteed. In the preferred scheme, the second user or the third user can input key data to the help seeking site to ensure the completion of the mutual-help task, the set condition is the safety guarantee provided by considering the age and the actual condition of the aged-care mutual-help object, meanwhile, when the old people receiving the mutual-help task cannot complete the task, the old people can also be used as the basis for judging the health condition of the old people, and certainly, the other old people receiving the task can complete the task to form the mutual-help data. The data processing module generates the time difference t from the generation of the operation information to the generation of the feedback information_xWhether alarming is needed or not is judged, and the effectiveness of the treatment of the help seeking behavior of the old is ensured.

The key data comprises second identifications of the first user, the second user and the third user, and the received multiple mutual-help tasks can be distinguished by the old people who are more keen to provide mutual-help through the second identifications, so that the condition that the key data corresponds to errors is avoided.

In order to better judge the mutual aid request, the old people in the whole network can more objectively and rationally judge the mutual aid behavior, and the operation information comprises identification of daily care, emergency rescue and other three functions. The daily care can include conventional medical assistance, such as medicine feeding, medical article replacement, medical monitoring and the like, emergency rescue is performed when the old people face serious medical conditions, such as falling, serious trauma or sudden severe discomfort, and other conditions can include psychological need of consolation of the old people, and other users can obtain mutual assistance tasks suitable for the old people according to different operation information for helping the old people. All information in the network is timely disclosed and effectively transmitted, but specific help content is not disclosed, and the privacy of the old is protected.

It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
