Description

Technical Field

[0001] The present invention belongs to the field of nursing technology, and specifically relates to a smart elderly care method and system. Background Art

[0002] As the aging of society deepens, the safety and health monitoring of the elderly has become an increasingly prominent social issue. Most of the existing elderly care solutions rely on video surveillance or wearable health monitoring devices. Although video surveillance can provide intuitive picture information, there is a problem of infringing the privacy of the elderly, especially for private spaces such as bathrooms and bedrooms. In addition, the video surveillance system cannot actively monitor the health status of the elderly, such as abnormal heart rate, difficulty breathing, etc. Wearable health monitoring devices, such as wireless bracelets, can monitor the elderly's heart rate, blood pressure and other physiological indicators in real time, but there is a problem that the elderly are prone to forget to wear or frequently charge, which reduces the convenience and continuity of use.

[0003] Currently, there is a lack of nursing products designed specifically for the elderly that can fully cover all areas of the home while protecting privacy. Especially for those elderly people with limited mobility or memory loss, traditional emergency call methods (such as pressing a button) may fail because the elderly cannot operate in time in an emergency, resulting in missing the best time for rescue.

[0004] When it comes to caring for the elderly, most children who have left home still use the installed webcam images to learn about the elderly’s situation during their spare time. They are unable to detect abnormalities in time, resulting in missing the best time for rescue. They also cannot be used in private places such as toilets, resulting in blind spots in the scenes.

[0005] In general, the existing technology cannot actively monitor the physical and mental state of the elderly, such as abnormal heart rate, falls, sudden death, etc. It is also impossible to fully cover all places in the home without taking into account privacy. In case of emergency, relevant personnel cannot be notified in time. Summary of the invention

[0006] The purpose of the present invention is to provide a smart elderly care method and system, which can realize active detection and passive triggering of alarms to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides a smart elderly care method, comprising the following steps: S1: Establish a communication connection between the host and at least one FDx sensorless detector through the DECT wireless protocol; S2: The FDx sensorless detector monitors the elderly's physical condition in real time through millimeter wave radar, including falls, long-term sitting, staying, breathing, heart rate, getting out of bed, and sudden death; S3: When the FDx sensorless detector detects an abnormal state, it asks the elderly whether they need to call for help through voice. If the elderly answer cancel, the next step will not be executed; if there is no answer or the answer is that help is needed, the next step will be executed; S4: The FDx sensorless detector sends the abnormal state data to the host through the DECT wireless protocol; S5: After the host receives the abnormal state data, it transmits the data back to the background server through the network, and initiates a call based on the preset emergency contact list.

[0008] Preferably, the host supports configuring WIFI SSID and PASSWORD via Bluetooth.

[0009] Preferably, the host is connected to the Internet via Ethernet, WIFI or 4GCat1 to achieve data exchange with the backend server.

[0010] Preferably, the host supports establishing wireless communication networking with third-party Zigbee devices, and the third-party Zigbee devices include but are not limited to water immersion, door magnets, smoke, and gas sensors.

[0011] Preferably, the FDx sensorless detector can transmit the audio segment after voice keyword recognition to the host through the DECT wireless protocol, and the host performs secondary confirmation.

[0012] It also includes: S6: the host establishes a wireless communication connection with the wireless bracelet, and when the emergency button on the wireless bracelet is long pressed, the wireless bracelet is activated and sends an emergency signal to the host.

[0013] Another aspect of the present invention provides a smart elderly care system, comprising: The host is used to establish a communication connection with the FDx non-sensing detector, receive abnormal status data, and interact with the background server; At least one FDx sensorless detector is used to monitor the elderly's physical condition through millimeter wave radar and ask the elderly whether they need help through voice; A wireless bracelet that activates and sends an emergency signal to the host when the emergency button is long pressed; Third-party Zigbee device, used to send environmental monitoring data to the host.

[0014] Preferably, the host has voice call capability and can make voice calls through the Internet or a list of ordinary telephone numbers.

[0015] Preferably, the host supports the extension of voice call distance and range through the Dect wireless protocol.

[0016] Preferably, the FDx non-contact detector recognizes the elderly's call for help through voice keywords, and sends the audio clip to the host through the DECT wireless protocol, which performs secondary confirmation processing.

[0017] Technical effects and advantages of the present invention: Compared with the prior art, the present invention provides a smart elderly care method and system, which has the following advantages: The present invention realizes contactless real-time monitoring of the physical state of the elderly by using the combined use of the host and the FDx non-contact detector using millimeter-wave radar technology. The host supports button and voice keyword recognition to trigger the alarm; the FDx non-contact detector will confirm the elderly's real needs through voice inquiries. Only when it is confirmed that help is needed will it notify the host to send an alarm message and trigger a call. This method can not only promptly notify relevant personnel when emergency situations such as the elderly falling or having an abnormal heart rate are detected, but also confirm the elderly's real needs through voice inquiries, thereby avoiding false alarms; in addition, the emergency button design of the wireless bracelet provides the elderly with another simple way to ask for help, and a distress signal can be quickly sent even when they are unable to speak. This method effectively solves the problems of the prior art in terms of lack of comprehensive coverage, timely response, and respect for the privacy of the elderly, thereby improving the safety and comfort of the elderly's lives. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 This is a flow chart of the smart elderly care method of the present invention; Figure 2 It is a structural schematic diagram of the smart elderly care system of the present invention. DETAILED DESCRIPTION

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] The embodiment of the present invention provides a smart elderly care system, and the whole elderly care system is mainly divided into two parts: intelligent hardware system and background system. The intelligent hardware system is divided into four parts: SC01 host, FDx non-sensing detector, wireless bracelet, and third-party Zigbee device.

[0021] Specifically, Figure 2As shown, the host is used to establish a communication connection with the FDx non-sensing detector, receive abnormal status data, and exchange data with the background server; at least one FDx non-sensing detector is used to monitor the physical condition of the elderly through millimeter wave radar, and ask the elderly whether they need to call for help through voice; the wireless bracelet is used to activate and send an emergency signal to the host when the emergency button is long pressed; the third-party Zigbee device is used to send environmental monitoring data to the host.

[0022] Among them, the main functions of the SC01 host are as follows: Capable of voice calls: divided into network calls and ordinary calls. Network calls can establish voice calls through the Internet, while ordinary calls are made through a pre-set mobile phone number or landline number list to realize voice calls.

[0023] With the ability to recognize voice keywords, the elderly can use preset keywords such as emergency, call my family, and call for help to trigger emergency calls, calls to family members, and calls for help respectively.

[0024] It has the ability to trigger calls with buttons, and also supports three calling modes: emergency calls, calls to family members, and calls for help.

[0025] It has 868 wireless communication capability, can establish communication with low-power wireless bracelets, and receive button trigger events from wireless bracelets in real time.

[0026] With dect wireless voice expansion capability, the distance and range of voice calls can be expanded to various places, such as bathroom, bedroom, living room, kitchen, study, etc.

[0027] It has Zigbee wireless communication networking capability and can seamlessly connect to third-party Zigbee devices such as water immersion, door magnets, smoke sensors, and gas sensors.

[0028] It has multiple capabilities for accessing the Internet and can support Ethernet, WIFI, and 4GCat1 to access the nursing network.

[0029] Support Bluetooth configuration function, you can configure WIFI SSID\PASSWORD to access WIFI.

[0030] It supports remote OTA upgrade function, and software-related functions and voice recognition algorithms can be continuously updated and iterated.

[0031] Among them, the main functions of FDx non-sensing detector are as follows: It has the capabilities of wireless voice expansion and wireless communication, and establishes voice and data links with the SC01 host through the Dect wireless protocol. When an abnormal event or a call for help is detected, the data is transmitted to the SC01 host through the data link. The SC01 host actively initiates a voice call and serves as a bridge for two-way voice transmission. Through DECT, a voice call link is established between the user's APP or mobile phone and the FDx non-contact detector, so that the FDx non-contact detector can directly have voice conversations with users who care about the elderly and understand the elderly's on-site situation in a timely manner.

[0032] With voice keyword recognition capability, the elderly can trigger an emergency call through preset keywords, such as emergency. When the millimeter-wave radar detects an abnormality, it will also ask the elderly whether they need to call for help. The elderly can cancel the call for help through preset keywords, such as imfine.

[0033] With millimeter wave radar monitoring function, it can realize real-time fall detection, sedentary detection, resident detection, breathing detection, heart rate detection, bed leaving detection, sudden death detection alarm and other functions 24 hours a day. When any of the above events are detected, the data will be transmitted to the SC01 host through the dect data link, and the SC01 host will then transmit the event back to the background through the network, so as to notify the user in time.

[0034] Supporting OTA upgrade function, the millimeter-wave radar algorithm can be continuously updated and iterated.

[0035] Specifically, the elderly can call for help through voice keywords, or the abnormal situation can be detected by radar, or the elderly can trigger the call for help through the bracelet worn on them. For the scenario of false alarm, voice recognition is used for secondary confirmation. When a fall is detected, the user will be prompted by voice whether to cancel the alarm. If the user explicitly says "cancel the alarm", the fall event will be canceled. Otherwise, the alarm notification will be triggered after the specified countdown.

[0036] Among them, the main functions of third-party Zigbee devices are as follows: Currently, water sensors, door magnetic sensors, smoke sensors, and gas sensors can be connected to the SC01 host, and the SC01 host will send the detection status of these devices back to the backend through the network. Furthermore, any product that supports the Zigbee3.0 standard can be connected.

[0037] Exemplarily, the millimeter wave radar and voice recognition keyword triggering process is as follows: The SC01 host can establish communication with multiple FDx non-contact detectors at the same time through the DECT protocol. According to the following process, the emergency event triggered by the FDx non-contact detector will be connected to the user's mobile phone or APP for a two-way voice call, so that the user can understand the elderly's physical condition at the first time and obtain the most precious rescue time.

[0038] After the FDx sensorless detector is powered on, it will be in a state of waiting to be connected.

[0039] The SC01 host will poll the registered FDx sensorless detector device at intervals to try to handshake and establish a connection.

[0040] After the SC01 host establishes a connection with the FDx sensorless detector, the FDx sensorless detector will synchronize the latest events to the SC01 host and maintain the connection status, so that any events of FDx can be transmitted to the SC01 host in real time.

[0041] After receiving the event, the SC01 host will determine whether it is an emergency event. If it is not an emergency event, it will only send the event notification to the cloud, which will then send it to the corresponding APP.

[0042] If the SC01 host receives an emergency event, in addition to transmitting the relevant event message to the cloud, it will also make a voice call to the user (network call or ordinary call) according to the current configuration given by the cloud to establish a two-way voice call.

[0043] You can also receive notifications of common events during the period when the user answers the call or hangs up.

[0044] After the FDx non-contact detector device is powered off, the SC01 host can also detect the offline status and notify the user.

[0045] Exemplarily, the wireless bracelet triggering process is as follows: The SC01 host has a built-in 868 receiver, and the wireless bracelet has a built-in 868 transmitter. In addition, the SC01 host not only supports 868MHz, but also supports four frequency bands: 315MHz, 433MHz, and 915MHz.

[0046] Under normal circumstances, the entire hardware system of the wireless bracelet is powered off. When the user presses and holds the button, the capacitor is charged. When a certain voltage is reached, the MOS tube is controlled to connect to the MCU power supply, and the MCU begins to take over the MOS tube. At this time, the button can be released. After the MCU completes the relevant initialization, it sends an emergency event to the SC01 host through the 868 transmitter. After completion, the MOS tube is controlled to turn off the power and enter the hardware power-off state to achieve ultra-low power standby.

[0047] After the SC01 host receives the emergency event triggered by the 868 transmitter, it makes a voice call to the user (network call or ordinary call) according to the current configuration given by the cloud and establishes a two-way voice call.

[0048] On the other hand, the present invention provides a smart elderly care method, which aims to realize non-contact real-time monitoring of the elderly's physical state through the combined use of a host and an FDx non-sensing detector, using millimeter-wave radar technology. This method can not only promptly notify relevant personnel when emergency situations such as elderly falls and abnormal heart rates are detected, but also confirm the elderly's real needs through voice inquiries, avoiding false alarms. The details are as follows: like Figure 1 As shown, the above-mentioned smart elderly care method includes the following steps: S1: Establish a communication connection between the host and at least one FDx non-sensing detector through the DECT wireless protocol; Furthermore, the host supports configuring WIFI SSID and PASSWORD via Bluetooth, which is convenient for users to set up the network. The host accesses the Internet through Ethernet, WIFI or 4GCat1 to achieve data exchange with the backend server. The host supports establishing wireless communication networking with third-party Zigbee devices, including but not limited to water immersion, door magnets, smoke, and gas sensors, further enhancing the system's environmental monitoring capabilities.

[0049] S2: The FDx non-contact detector uses millimeter wave radar to monitor the elderly's physical condition in real time, including falls, long-term sitting, staying, breathing, heart rate, getting out of bed, and sudden death; this contactless monitoring method not only protects the privacy of the elderly, but also ensures the accuracy of monitoring.

[0050] S3: When the FDx sensorless detector detects an abnormal state, the elderly person is asked by voice whether he needs help. If the elderly person answers "cancel", the next step is not executed; if the elderly person does not answer or answers "need help", the next step is executed; S4: The FDx sensorless detector sends the abnormal status data to the host through the DECT wireless protocol; the FDx sensorless detector can transmit the audio clip after voice keyword recognition to the host through the DECT wireless protocol, and the host performs secondary confirmation.

[0051] Speech recognition algorithms may also have the problem of misidentification. Usually, using a larger model and consuming more examples can greatly improve the accuracy of the speech recognition algorithm. Therefore, in order to further reduce misidentification and improve the recognition rate, when the sub-device recognizes an audio clip of a suspected specified keyword, it will transmit the clip to the host, and use the host's high-performance CPU to use a larger model for secondary recognition confirmation. Different from transmitting to the cloud for recognition, the sub-device uses DECT to transmit audio to the host, which has the following advantages: 1. There is no need to connect to the Internet, there is no traffic problem, and real-time performance is not affected by the network. 2. For places with high privacy requirements, there is no need to worry about audio being maliciously used or leaked in the cloud. 3. Make full use of existing hardware resources to reduce the hardware cost of sub-devices.

[0052] S5: After receiving the abnormal status data, the host transmits the data back to the background server through the network, and initiates a call according to the preset emergency contact list.

[0053] In another embodiment, the process further includes S6: the host establishes a wireless communication connection with the wireless bracelet, and when the emergency button on the wireless bracelet is long pressed, the wireless bracelet is activated and sends an emergency signal to the host.

[0054] The main functions of the wireless bracelet are as follows: It has ultra-low power consumption capability. When the button is not long pressed, the entire hardware system is powered off and does not work. When the button is long pressed for 3 seconds, the hardware will be powered on and the emergency signal transmission action will be activated.

[0055] It has 868Mhz wireless transmission capability (not only supports 868MHz, but also supports four frequency bands of 315MHz, 433MHz, and 915MHz). When the button is activated, the data will be sent to the SC01 host. The SC01 host will directly trigger an emergency call to the designated user's mobile phone or APP based on the preset network call or ordinary call configuration.

[0056] Through the combined use of the host and the FDx non-contact detector, comprehensive monitoring of the elderly's physical condition is achieved, covering various conditions such as falls, long-term sitting, staying, breathing, heart rate, getting out of bed, sudden death, etc.

[0057] Contactless monitoring: Using millimeter-wave radar technology for contactless monitoring protects the privacy of the elderly while improving the accuracy and reliability of monitoring.

[0058] Real-time response: Through voice inquiry and emergency button design, we ensure that when an abnormal state is detected, the real needs of the elderly can be confirmed in time, and the emergency contact process can be quickly initiated to avoid false alarms.

[0059] Multi-mode communication: The host supports multiple communication modes (Ethernet, WIFI, 4G Cat1) to ensure the stability and reliability of data transmission.

[0060] Environmental monitoring: The networking of the host and third-party Zigbee devices enhances the system's environmental monitoring capabilities, enabling timely detection and handling of safety hazards such as flooding, door magnets, smoke, and gas leaks.

[0061] User-friendly: supports WIFI configuration via Bluetooth, which is convenient for users to set up the network and improves the user experience; it can also be connected to the mobile phone APP to see more alarm information and configuration functions.
