BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 This is a flow chart of the elderly anti-lost supervision system of this application. DETAILED DESCRIPTION

[0017] The following is combined with Figure 1 This application is described in further detail.

[0018] The embodiment of the present application discloses a system for preventing loss of an elderly person.

[0019] Reference Figure 1 , an anti-lost supervision system for the elderly includes a positioning module and a remote background.

[0020] Among them, the positioning module includes a packaging shell and a controller, a positioning chip, a communication module, a pressure switch and a massage prompt mechanism integrated in the packaging shell. The positioning module is used to be installed in the sole (it should be noted that in other embodiments, the positioning module can also be installed in other wearable devices, such as: necklaces, bracelets, belts, etc.), the massage side of the massage prompt mechanism faces the user's feet, the sensing side of the pressure switch faces the user's soles, and the pressure switch is connected in series to the controller power circuit. When the pressure from the user's soles is sensed, the pressure switch is turned on, the positioning module is powered on and started, and positioning data is generated.

[0021] The remote backend includes the server and the personal terminal connected to the server; Among them, the remote background configuration is: receiving positioning data; When receiving a location query request initiated by a personal terminal (the user or his / her family's smartphone, iPad, electronic watch, etc. downloaded APP) through the APP, the matching positioning data is output based on the electronic map and the requester's identification information; It can be understood that a database is preset, and the database is used to store the user's identity information (photo, mobile phone number), bound family member information (mobile phone number, home address) and device ID, as well as real-time received positioning data. The database design contains necessary data indexing and search algorithms to support fast data retrieval and matching. Therefore, according to the location query request initiated by the personal terminal, the database is retrieved to match the positioning data of the device ID corresponding to the requester. Secondly, the system marks the received positioning data on the map through integration with the electronic map service to generate visual location information. Family members can query and view the real-time location information of the elderly through the application installed on the smartphone or other mobile terminal device, after entering the necessary identity authentication information. The application provides a user-friendly interface, so that family members can easily find the location of the elderly on the electronic map.

[0022] Based on the matching positioning data, it is determined whether the user is in the returning state. The user's movement trajectory can be monitored in real time to calculate the distance between the user's current location and the preset home address. If the distance gradually decreases and a certain movement trajectory is highly similar to the historical movement trajectory, it can be inferred that the user may be in the returning state.

[0023] If so, the current positioning data and the preset home address positioning data are called for difference comparison analysis, and the comparison results are output; it can be understood that if the user is in the return state, and the user has not moved after staying in the non-home address area for the preset T1 time, the current positioning will be compared with the preset home address location.

[0024] Based on the comparison results, the massage reminder mechanism is controlled to give massage reminders to the user; regarding the massage reminder mechanism, it is a massager structure pre-installed on the sole. When it receives the start control command sent by the remote background to perform the massage action, the massager structure realizes vibration, rolling or tapping effects, which not only serves as a reminder, but also massages the soles of the user's feet to make the user relax appropriately.

[0025] If the user's positioning data has not been updated within the T2 duration, the preset matching prompt will be output to the personal terminal; for example: if the current positioning is significantly different from the preset home address positioning and the user has not moved within the T2 duration after the massage prompt, the corresponding prompt will be matched: user return deviation warning; if the current positioning is slightly different from the preset home address positioning, the corresponding prompt will be matched: the user is near the address, thereby reminding family members of the user's location.

[0026] The personal terminal is pre-installed with a private key and a public key that are negotiated and matched with the positioning module. The positioning module is pre-installed with a public key. The remote backend also includes a third-party terminal (other people's electronic devices, such as mobile phones and tablets). The third-party terminal is pre-installed with a public key. The communication module is configured as follows: when the third-party terminal detects the Bluetooth signal pre-installed in the positioning module, the third-party terminal receives the positioning data and the public key of the positioning module, and sends the positioning data and the public key anonymously to the server; the personal terminal obtains the positioning data from the server.

[0027] Specifically, in this embodiment, wireless communication can use BLE's Find My technology to assist in positioning through the Apple device network, or use BLE's Find My Device technology to assist in positioning through the Android device network, both of which use Bluetooth low energy technology and crowdsourcing network concepts to help users achieve communication positioning. Taking BLE's Find My technology as an example, a personal terminal (a mobile phone or tablet of the user or his family) is pre-installed with the Find My App, and when paired with a Find My compatible positioning module, a pair of secret keys will be negotiated between them, in which the private key and the public key are retained on the electronic device of the personal terminal, and the public key is stored in the positioning module.

[0028] The paired positioning module will operate as a BLE beacon, continuously broadcasting a changing secret key derived from the public key to ensure the security and privacy of the signal. When third-party terminals (other Apple devices, such as iPhone or iPad) are nearby, they can detect the broadcast of this BLE beacon. These devices will then package the received secret key together with their own positioning data and upload it anonymously to Apple's server. Personal terminals can obtain these data reports containing positioning information from the server through the Find My App and see the user's location on the map in the APP.

[0029] The Find My solution based on BLE technology can not only provide rough positioning outdoors, but also provide centimeter-level positioning accuracy for devices that support UWB. The Find My network can use UWB technology to provide centimeter-level positioning accuracy, and thus can achieve precise indoor positioning by combining UWB technology. The location can be determined by using the surrounding Apple device network, thus providing users with a comprehensive and accurate positioning service.

[0030] In another embodiment of the present application, the communication module is further configured to: send the pre-stored family contact information to the third-party terminal after the third-party terminal detects the Bluetooth signal pre-installed in the positioning module and establishes a connection.

[0031] It is understandable that if the user's positioning data is not updated within the T2 duration, the third-party terminal detects the Bluetooth signal of the positioning module, and after automatically interconnecting, searches in the database and sends the family contact information (mobile phone number) matching the current positioning module device ID to the third-party terminal, so that the third-party terminal can directly contact the user's family contact. The Bluetooth signal of the positioning module can be kept on continuously or turned on manually by family members.

[0032] In another embodiment of the present application, the positioning module is configured to: periodically execute a preset function self-check process; Specifically, when the positioning module is powered on, it will first perform a quick self-test to check whether the hardware is working properly and test its signal reception ability; the positioning module will process the received data and then verify whether the processed data is accurate to ensure the accuracy of the location information; the positioning module will also calibrate the time synchronization to ensure that the internal clock of the module is synchronized with the time of the outside world, which is crucial for the accuracy of positioning; through a series of preset test procedures, the performance of the positioning module is evaluated to see whether it meets the standards, including indicators such as positioning accuracy and response speed. If any problems are found during the self-test process, the positioning module will record the error information and report it to the main system through the appropriate interface; in order to keep the positioning module at its best performance throughout the operation, this self-test process will be automatically executed periodically, and can be set to a cycle of 3 days, and automatically executed every 3 days.

[0033] Through periodic functional self-test, the positioning module can be self-checked to see whether its functions are operating normally, so that the positioning module can provide more accurate and reliable positioning services.

[0034] When the function self-check process is triggered, if it is detected that the positioning module is in the communication state, the self-check stop control instruction is output to reduce energy waste.

[0035] In another embodiment of the system, the remote backend is further configured as: Based on the matched positioning data, it periodically monitors whether there are other users within a preset range around the matched positioning data, and feeds back the monitoring results to the personal terminal.

[0036] Specifically, first, the system will obtain the current user's positioning data from the positioning module; according to the needs, set a preset range, for example: set the user's location as the center and a radius of 5 kilometers as the preset range. Within the set time interval (for example: 1 hour as a detection cycle), the system will periodically check whether there is positioning data of other users within the preset range. The system will analyze the collected positioning data and match it with the location data of the target user to determine whether there are other users within the preset range. If other users are detected within the preset range, the system will feed back this monitoring result to the personal terminal so that the user can understand the surrounding situation. If an emergency occurs and help is needed, it is convenient for family members to contact other users for help.

[0037] Secondly, when monitoring user locations, the system should ensure that appropriate privacy protection measures are taken to avoid leaking sensitive user information. Secondly, the system will update the monitoring results in real time based on the user's movement to ensure accurate information. If an abnormal situation is found during the monitoring process, such as abnormal positioning data or a large number of unknown users within the preset range, the system should be able to handle and report the abnormal situation in a timely manner. Secondly, the system establishes a user feedback mechanism, allowing users to make suggestions or feedback on monitoring results in the personal terminal APP to continuously optimize and improve the monitoring system.

[0038] In another embodiment of the system, the remote backend is further configured as: If signal loss or instability is detected, the last received positioning data within the target time period is called; it is understandable that when the signal is lost or unstable, the system will call the last received valid positioning data within the target time period as a reference for the current position.

[0039] Based on the last received positioning data, a missing person request is sent to a third party with which cooperation has been established in advance within a preset range; it is understandable that the third party includes notifications to nearby security agencies, community service centers or other resources that can assist in finding the missing person.

[0040] Receive image data from cameras preset in streets and parks transmitted by third parties; this data may come from city surveillance systems, community surveillance or other public safety cameras.

[0041] Based on image analysis and recognition, the system will screen and determine whether there is an image of the user that is being sought in the image, and output the screening results. Through image processing and analysis technology, the system will screen the camera image data to determine whether there is an image of the user that is being sought in the image. This process may involve facial recognition, clothing matching or other biometric recognition technologies. Once the system identifies the target user in the image, it will output the screening results and provide them to relevant agencies and family members for further action.

[0042] In another embodiment of the system, the remote backend is further configured as: Based on the matched positioning data, obtain monitoring data from the monitoring cloud of the specified community; Specifically, a connection is established with the monitoring cloud of the designated community to ensure smooth acquisition of monitoring data. Authentication is then performed to ensure that only authorized users or systems can access monitoring data, and a data request is sent to the monitoring cloud, clearly specifying the required monitoring data type and time range.

[0043] Determine the user's travel time based on monitoring data; Specifically, after the monitoring cloud responds to the request, it receives the returned monitoring data and processes the received monitoring data, such as decoding and format conversion, for subsequent analysis. The processed monitoring data is matched with the existing positioning data to determine the user's travel time and route.

[0044] If the user's travel time meets the preset abnormal travel time, an abnormal travel reminder is output to the personal terminal.

[0045] Specifically, the user's travel habits and time patterns are analyzed based on the travel time information in the monitoring data. The user's travel time is compared with the preset normal travel time to determine whether it meets the abnormal travel time; if the judgment result is that it meets the abnormal travel time, abnormal travel prompt information is generated and output to the personal terminal so that family members can understand it in time and take corresponding measures.

[0046] In another embodiment of the present system, a Micro Xbee module is also included, which is used for wireless communication with other nearby users and wirelessly connected to the communication module and the remote background.

[0047] If the signal is lost, the XBee module is enabled to communicate with the positioning modules of other users nearby, and the data is transmitted again and again through the positioning modules of other users, so as to send the location data out of the interference area. It can be understood that the MicroXBee module is a micro wireless module that supports ZigBee 3.0. It can communicate with devices such as microcontrollers through the serial port and quickly connect the devices to the ZigBee network. The communication between the XBee module and the microcontroller can be carried out in transparent mode or API mode. In transparent mode, the microcontroller directly sends data to the XBee module through the serial port, and the module wirelessly transmits data to the remote XBee module according to the ZigBee protocol. The remote module then transmits the data to another microcontroller through the serial port, which can achieve long-distance and low-power data transmission.

[0048] In another embodiment of the present system, it further includes a wireless charging module and a charger matching the wireless charging module; wherein the wireless charging module is installed in the sole and electrically connected to the positioning module, and the charger is installed in a designated area.

[0049] Specifically, the wireless charging module receives wireless energy from the charger and converts the energy into electrical energy to charge the positioning module. In this embodiment, this type of wireless charging module can transmit energy using electromagnetic induction.

[0050] The charger is installed in a designated area, such as at home or other places where users can charge conveniently. The charger generates an alternating electromagnetic field. When the wireless charging module enters the effective range of this field, it can receive energy through the above-mentioned electromagnetic induction method and convert it into direct current to charge the positioning module, thereby allowing users to charge the positioning module in the sole without physically connecting the charging cable, which provides convenience.

[0051] The embodiment of the present application also discloses a method for preventing loss of an elderly person.

[0052] The method for preventing loss of elderly persons uses any of the above-mentioned systems for preventing loss of elderly persons.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
