Detailed Description

In order to make the objects, technical solutions and advantages of the present disclosure more clear, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without making any creative effort belong to the protection scope of the present specification.

In order to realize effective monitoring of an infant emergency and thus ensure health and safety of the infant, the present specification provides a system for monitoring the infant emergency, where the system includes a wearable device worn on the infant, a data relay for receiving pronunciation information sent by the wearable device, and a client installed in a terminal carried by a user, as shown in fig. 1.

Fig. 1 is a schematic diagram of a system for monitoring an infant during an emergency event provided herein.

In the system for monitoring the state of an infant provided in this specification, a wearable device may be worn on the infant (for example, at an arm) to collect pronunciation information issued by the infant and send the pronunciation information (i.e., target pronunciation information) meeting a preset pronunciation warning rule to a data relay. The data relay may be a separate device, i.e. the wearable device worn on the infant and the data relay may be two different hardware devices. The method comprises the steps of receiving target pronunciation information sent by wearable equipment through communication connection established between the wearable equipment and the wearable equipment, determining emergencies and incident positions of infants through the received target pronunciation information, and sending corresponding alarm information and the incident positions to a client of a user. After the client receives the alarm information and the incident position based on the relied terminal, the alarm information and the incident position can be displayed to the user, so that the user can timely return to the infant to take care of the infant, and the health condition of the infant is effectively guaranteed.

For convenience of description, the method for monitoring the status of an infant provided in the present specification will be described below mainly with a wearable device as an execution subject, and as for other devices in the entire system, the method will be described in a suitable place in the present specification.

The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.

Fig. 2 is a flow chart of a method for monitoring an infant during an emergency event, comprising the steps of:

s201: the wearable equipment collects pronunciation information of infants.

In this specification, a wearable device may be worn on an infant in a manner similar to a smart band, wherein the wearable device may be provided with a processor, a pronunciation information collector (e.g., a Microphone (MIC)), a communication module, and the like. The pronunciation information collector is used for collecting pronunciation information sent by the infant, the processor is used for processing the collected pronunciation information, and the communication module is used for sending the pronunciation information processed by the processor.

It should be noted that, in practical applications, an infant may also make a normal sound, that is, a sound that does not meet an unexpected condition, and the method for monitoring the infant condition provided in this specification is actually to acquire pronunciation information of the infant when the infant is in an unexpected condition, so that if all the acquired pronunciation information is sent to the data relay, the power consumption of the wearable device will certainly increase.

Therefore, in this specification, the wearable device may perform data analysis and filtering on the collected pronunciation information to send the pronunciation information satisfying the preset pronunciation warning rule to the data relay. The processor for screening the pronunciation information can be in various forms, for example, a common single chip microcomputer can be used (for example, an ARM, a cortix-M1 series can well realize local pronunciation information screening of the wearable device, the main frequency can be more than 40M, correspondingly, the RAM equipped in the wearable device can be more than 64K, and the ROM can be more than 128K). Therefore, the communication module in the wearable device can be dormant most of the time to save the electric quantity. Of course, other forms of microprocessors may suffice and are not illustrated in detail herein.

Of course, other devices, such as an acceleration sensor, a temperature sensor, etc., may also be provided on the wearable device. The acceleration sensor can acquire data of the infant when the body of the infant moves, when the infant has an emergency such as falling off the bed, the acceleration sensor can acquire corresponding sensing data in time and send the sensing data to the data relay, the data relay can determine the emergency when the infant falls off the bed through the acquired sensing data, and then corresponding warning information is sent to a client of a user, so that the user can get back to the body of the infant in time.

For the temperature sensor, when the body temperature of the infant rises to exceed the normal body temperature, the wearable device can acquire body temperature data of the infant through the temperature sensor and send the acquired body temperature data to the data repeater, the data repeater determines that the body temperature of the infant exceeds the normal body temperature through the received body temperature data, and then corresponding alarm information can be sent to a user, so that the user can get back to the body of the infant in time and take the infant to seek medical advice in time. The use of other sensors is not illustrated in this context.

The user mentioned in this specification may be a caregiver who takes care of an infant, such as a parent (e.g., a parent) of the infant, or a caregiver who takes care of the infant. And the wearable equipment mentioned above can be equipped with and set for the jack, and charging wire can be inserted to jack department to realize the charging of wearable equipment. Of course, the wearable device may also operate by mounting a battery.

Further, the external material of the wearable device may be made of plastic, metal material, etc., and certainly, for the convenience of wearing by the infant, a lighter and more flexible silicone material may also be used, and the external material of the wearable device is not limited in this specification.

In this specification, in order to further increase the alarm range for the infant, the data relay and the wearable device may be placed in different spatial areas that are not separated by a set distance, for example, the wearable device may be in a bedroom when the wearable device is worn on the infant, and the data relay may be placed in a living room, where the bedroom and the living room are different spatial areas. Therefore, the distance between the wearable device and the data relay does not exceed the set distance, if the distance is too long, the wearable device may not be in communication connection with the data relay, and accordingly, the acquired target pronunciation information cannot be sent to the data relay.

S202: and carrying out data analysis on the pronunciation information to identify whether the pronunciation information meets the preset pronunciation warning rule or not.

After the wearable device collects pronunciation information sent by the infant, the wearable device can perform data analysis on the pronunciation information to identify whether the collected pronunciation information meets a preset pronunciation warning rule or not, and if so, the collected pronunciation information can be sent to the data relay as target pronunciation information in a subsequent process. The pronunciation information conforming to the preset pronunciation warning rule can be understood as pronunciation information that the infant will give out when an emergency occurs, such as crying.

Specifically, the wearable device can extract corresponding pronunciation characteristics from the collected pronunciation information, and after the extracted pronunciation characteristics are determined to meet preset pronunciation warning rules, the collected pronunciation information is used as target pronunciation information. In practical applications, the infant cry often shows certain features, such as higher pitch, larger voice, and mostly vowels (such as cry in o). For these features, the pronunciation warning rules mentioned in this specification may include a first warning rule, a second warning rule, and a third warning rule. If the number of the alarm conditions is met, the pronunciation characteristics can be used as target pronunciation information, and the specific numerical value of the set condition number can be determined according to actual requirements, for example, the numerical value can be 1, namely, any one of the pronunciation characteristics can be met, or 3, namely, all alarm rules need to be met.

For the first alarm rule, if the wearable device determines that the pronunciation volume corresponding to the collected pronunciation information is not less than a specified volume threshold (e.g., 40 dB), it is recognized that the pronunciation feature extracted from the pronunciation information satisfies the first alarm rule, that is, if the volume corresponding to the collected pronunciation information is determined to be too large, it may be determined that the collected pronunciation information needs to be sent.

For the second alarm rule, if the wearable device determines that the pitch frequency corresponding to the collected pronunciation information is not less than a specified frequency threshold (e.g., 300 Hz), it is recognized that the pronunciation feature extracted from the pronunciation information satisfies the second alarm rule. That is, if it is determined that the pitch corresponding to the collected phonetic information is too high, it may be determined that the collected phonetic information needs to be transmitted.

For the third warning rule, if the wearable device determines that the information amount of the vowel pronunciation information included in the collected pronunciation information is not lower than the specified information amount threshold, it is recognized that the pronunciation feature extracted from the pronunciation information satisfies the third warning rule. That is, if it is determined that the collected pronunciation information includes vowel pronunciation information such as "o" and the duration of the vowel pronunciation information is too long (for example, more than 3000 ms) (if the duration is too long, the description information amount is too much), it may be determined that the collected pronunciation information needs to be sent.

S203: if the fact that the pronunciation information accords with the pronunciation warning rule is determined, the pronunciation information is used as target pronunciation information, the target pronunciation information is sent to the data repeater on the basis of communication connection established between the data repeater and the data repeater, so that the data repeater determines an emergency occurring when the infant generates the target pronunciation information according to the target pronunciation information, determines the position of the infant in the overall space map when the infant generates the emergency according to a pre-stored overall space map of a location area and the orientation of a signal receiver receiving the target pronunciation information in the data repeater, and uses the position as an incident position, and sends warning information for indicating the occurrence of the emergency of the infant and the incident position to a terminal installed with the client when the position of the terminal installed with the client is determined not to exceed a communication distance threshold value capable of communicating with the data repeater, so that a user carrying the terminal with the client is reminded that the infant has the emergency occurred at the incident position.

The wearable device can send the collected pronunciation information to the data repeater located in the working range as the target pronunciation information after determining that the collected pronunciation information meets the preset pronunciation warning rule. The wearable device can establish communication connection with the data relay through a preset communication mode of short-distance communication, for example, communication connection modes such as bluetooth, wiFi, radio Frequency (RF) and the like. Of course, the communication connection may also be established by means such as 4G, 5G, etc.

The data relay may be located at a suitable location not too far from the wearable device and the data relay may be directly connectable to a power source (e.g., a wall outlet) to remain operational. Because the data relay needs to perform semantic analysis on target pronunciation information sent by the wearable device after receiving the target pronunciation information to determine an emergency event occurring to an infant, some powerful processors can be arranged in the data relay, for example, a rui-core micro-installation android system is taken as an example, RK3128 can well implement a semantic analysis function, a main frequency can be above 800M, on the basis, a RAM which can be equipped in the data relay is above 1GB, and a ROM which can be equipped is above 4 GB. Other available processors are not illustrated in detail herein.

In this specification, the data relay may be provided locally with a preset pronunciation library, and the pronunciation library is used for performing semantic analysis on the received target pronunciation information by the data relay. Based on this, after receiving the target pronunciation information, the data repeater can determine an emergency occurring when the infant sends the target pronunciation information through the pronunciation library, and send the alarm information corresponding to the emergency to the client of the user.

For example, if the data relay determines that the infant may cry due to hunger through the pronunciation library, corresponding warning information may be sent to the client of the caregiver to remind the caregiver to return to the infant to feed the infant in time. For another example, if the data relay determines that the infant may cry due to defecation at this time through the pronunciation library, corresponding alarm information may be sent to the client of the caregiver to remind the caregiver to return to the infant in time to replace the diaper.

In this specification, a plurality of signal receivers are provided in the data relay, and for each signal receiver, the signal receiver is provided in one orientation of the data relay for collecting information transmitted from the orientation. That is, once the data relay is located at one position, the data relay can receive the information sent from each direction through each set signal receiver, and when the target pronunciation information is received through a certain signal receiver, the data relay can determine which position in the whole space map the received information comes from according to the corresponding orientation of the signal receiver by combining the preset whole space map and the position of the data relay in the whole space map.

Specifically, after the data repeater receives the target pronunciation information, the position of the signal receiver for receiving the target pronunciation information in the data repeater can be determined, so as to determine the orientation of the signal receiver in the data repeater. This orientation may be understood as the orientation of the signal receiver on the left side of the data repeater, i.e. the left side of the data repeater, assuming that a signal receiver is disposed on the left side of the data repeater, and accordingly the signal receiver will receive the information transmitted from the left side of the data repeater.

Then, the data relay may determine the location of the infant in the overall space map when the infant has the emergency as the incident location, based on the overall space map of the location area stored in advance and the orientation of the signal receiver receiving the target pronunciation information in the data relay, in combination with the location of the data relay in the overall space map.

The global spatial map is used to represent the overall area where the data relay and the wearable device are located, e.g., the global spatial map may be used to represent an indoor map, similar to a house type map. The overall space map may be pre-entered into the data relay by the user through the client, or automatically drawn according to the echo by the data relay through broadcasting radar signals, or determined based on the user's house type map, and the description does not limit how the overall space map is entered into the data relay.

The position of the data repeater itself in the overall space map may be determined based on a position directly indicated by the user in the overall space map, or may be a position where the data repeater itself is detected by the broadcast radar when the overall space map is stored in advance.

The function of determining the incident position is that the infant may crawl, so the infant may not be always maintained in a small area, and therefore, the user can know the position of the infant at which the emergency happens in time by determining the incident position and sending the incident position to the user.

In this specification, the data relay may send the determined alarm information and the determined incident position to a client of a user in various manners, such as bluetooth and WiFi. In practical applications, the data relay may be far away from the terminal supported by the client of the user, for example, when a parent goes to buy a menu, in which case the data relay may not be able to directly send the determined alarm information and the incident position to the client of the user.

Therefore, when the position of the terminal provided with the client is determined not to exceed the communication distance threshold value capable of communicating with the data relay, the data relay can send the alarm information and the incident position to the client, so that the client can timely obtain the emergency and the incident position of the infant and go to the incident position for processing.

Of course, the system for monitoring the status of an infant provided in this specification may further include a server, where the data relay may send the target pronunciation information to the server when receiving the target pronunciation information and determining that the location of the terminal where the client is installed exceeds a communication distance threshold value that can be communicated with the data relay, and the server may determine an emergency event that occurs at this time for the infant according to the target pronunciation information and send corresponding alarm information and an event location to the client of the user through a mobile communication network, as shown in fig. 3.

Fig. 3 is a schematic diagram of a system for monitoring an infant emergency provided with a server according to the present disclosure.

The data repeater does not need to send the target pronunciation information to the server under the condition that communication connection with a terminal carried by a user fails, and a stronger pronunciation library can be integrated in the server, so that under normal conditions, the data repeater can directly send the target pronunciation information to the server without processing the target pronunciation information, and the server determines corresponding alarm information and sends the alarm information to the client side so as to remind the user of returning to the infant.

The above-mentioned terminal carried by the user can be in various forms, such as a smart phone, a tablet computer, a bracelet, and the like. The present specification does not specifically limit the form of the terminal.

For the server, after receiving the target pronunciation information sent by the data relay, the server may input the target pronunciation information into a preset semantic recognition model to determine an emergency that occurs when the infant sends the target pronunciation information, and send alarm information indicating that the infant has the emergency and an event sending position determined by the data relay to the client of the user through the mobile communication network.

The semantic recognition model mentioned above may be trained in advance, for example, by adopting a supervised mode, and the specific training process is not described in detail here. It should be noted that, after receiving the target pronunciation information, the server may use the target pronunciation information as a training sample, that is, store the target pronunciation information, and train the semantic recognition model according to the stored target pronunciation information and other sample pronunciation information, thereby further improving the semantic recognition capability of the semantic recognition model.

In addition, in this specification, the data relay may also be provided with a display screen, and accordingly, after determining an emergency event that occurs when the infant and the young child utters the target pronunciation information through a locally preset pronunciation library, the data relay may display alarm information (which may include the incident position) indicating the emergency event on the display screen for the user to view. Of course, the data repeater may also be provided with an alarm device, and when it is determined that an emergency occurs to the infant, the alarm device may give an alarm sound to prompt the user to get back to the infant as soon as possible to take care of the infant.

According to the method, once the wearable device worn on the infant collects the target pronunciation information used for indicating that the infant generates the emergency, the target pronunciation information can be immediately sent to the data repeater, the data repeater can determine the emergency generated by the infant based on the received target pronunciation information, and the client installed in the terminal carried by the user can remind the user in time, so that the user can be present around the infant in time to take care of the infant, the state of the infant is effectively monitored, and the health and safety of the infant are guaranteed.

Meanwhile, the wearable equipment can screen the collected pronunciation information to send the pronunciation information capable of indicating that the infant has an emergency to the data repeater, so that the electric quantity of the wearable equipment can be effectively saved, and the endurance of the wearable equipment is improved.

In this specification, the client may prompt the user to view the alarm information or give an alarm to the user in a certain manner, except that the alarm information and the incident position are displayed to the user through the supported terminal, for example, after receiving the alarm information, the client may send an alarm sound or vibrate through the terminal to prompt the user to view the alarm information or prompt the user to return to the infant in time to take care of the infant.

Further, the user may be in a relatively noisy environment, which may cause the user to be unable to view the alarm information and the incident position in time, for example, when the user is cooking in a kitchen, the sound emitted by the cooking device and the sound emitted by the range hood are too loud, which may cause the user to be unable to view the alarm information and the incident position displayed by the client in time, or an alarm based on the alarm information.

For this situation, if the client determines that the user still does not respond to the alarm information after the set time, the terminal may be controlled to issue a larger-sound alarm to prompt the user. For example, if the user carries a terminal equipped with the client, the client monitors that the alarm information is displayed for a set time, and the distance between the user (i.e., the terminal) and the infant is not shortened, the client can determine that the user still does not respond to the alarm information after the set time; for another example, if a button for determining that the user responds to the warning information is arranged in the interface displayed by the client, the client may determine that the user still does not respond to the warning information after the set time elapses after monitoring that the warning information is displayed, and the user still does not click the button. Other ways are not necessarily illustrated herein.

In this specification, if the server determines that the current emergency of the infant belongs to the disease emergency through the target pronunciation information, the server searches out a hospital and a corresponding infant doctor near the current position of the user while determining the corresponding alarm information, and sends the list of the searched hospitals and infant doctors together with the alarm information and the event sending position to the client for display.

Furthermore, the list can show the searched hospitals and doctors of infants to the user, and can also be provided with the option of appointment registration, and after the user determines that the infants need to see a doctor, the user can quickly make appointment registration through the options so as to bring the infants to the doctor.

In this specification, there may be more than one client of a user bound to the data relay or the server, and different priorities may be set for each user, and after the alarm information and the event location are determined, the data relay or the server may first send the alarm information and the event location to the user with the highest priority according to the priority order of the priorities, and if it is determined that the user cannot timely return to the infant for care, continue to send the alarm information and the event location to other users according to the priority order. Of course, the data relay or the server may also send the alarm information and the event location to all relevant users after determining the alarm information and the event location.

In addition, the data relay, the server, or the client mentioned above may also have a function of predicting the occurrence of an emergency, taking the data relay as an example, the data relay may count the time of the occurrence of the emergency of the infant every day, and determine a corresponding time distribution or a corresponding time law, and then the data relay may send a prompt message to the client in advance according to the time distribution or the time law when determining the time of the occurrence of the emergency of the infant, and correspondingly, the client may display the prompt message so that the user can arrive at the infant in advance according to the prompt message, so as to process the emergency of the infant in time.

The system for monitoring the state of the infant provided by the specification can also be provided with an image collector (such as a camera), and the image collector can be located in the same space with the wearable device. If the infant wearing the wearable device is located in a bedroom, the image collector can be also arranged in the bedroom, and when the infant is determined to have an emergency, the data repeater or the server can also control the image collector to capture the image of the infant and collect corresponding video data. Then, the image collector can send the collected video data to the data relay or the server, so that the data relay or the server sends the collected video data and the determined alarm information to the client side to be displayed to the user for viewing.

Further, after it is determined that the user responds to the warning information and goes to the infant, the server or the data repeater may send instruction information to the image collector to instruct the image collector to continue to collect video data so as to capture process video data of the emergency processed by the user going to the infant as an event reference video, and finally send the collected event reference video to the server. The server can analyze the event reference video to determine the event type of the emergency event, automatically label the target pronunciation information according to the event type, and train the semantic recognition model according to the labeled target pronunciation information.

For example, if the server determines that the emergency event occurring to the infant is crying caused by hunger (a picture of the infant fed by the user is recorded in the video data) through the received event reference video, the server may label the target pronunciation information uploaded by the data relay as a hunger condition, and train the semantic recognition model in the server according to the label.

It should be noted that the image collector may be awakened only when the infant has the emergency event, and the image collector may be in a sleep state at other times, so as to protect the security of the personal privacy of the user. And once the server marks the target pronunciation information, the uploaded event reference video can be deleted, so that the privacy of the user is further protected.

In practical applications, the caretaker may be far away from the infant, for example, the caretaker goes out to buy vegetables. In this case, after the caregiver knows that the infant has an emergency, the caregiver needs to return to the infant to take care of the infant as soon as possible and in time.

Based on this, in this specification, when the client responds that the distance between the user carrying the terminal and the wearable device exceeds the set distance, the client may show the user a riding device parking area near the position where the user is currently located, where the riding device parking area may include: shared bicycle parking areas, shared electric bicycle parking areas, etc. At the same time, the client can also show the user a route to the riding device parking area, as shown in fig. 4.

Fig. 4 is a schematic diagram of a client user showing a route to a riding device parking area as provided by the present specification.

In fig. 4, the cycling device parking area is located at the bottom right of the user (southeast direction), and the client can show the user in the interface a route from where the user is currently located to the cycling device parking area. The user can go to this equipment of riding parking region fast according to this route to through being located the equipment of riding (like sharing bicycle) that this equipment of riding parking region was parked, the infant is looked after to quick returning home.

Of course, if there is a cooperative relationship with the platform providing the shared bicycle or the shared electric bicycle service, the client may also show the shared bicycle or the shared electric bicycle near the current location of the user to the user, so that the user can directly locate the specific shared bicycle or the shared electric bicycle, thereby quickly returning home to take care of the infant.

It should be noted that, the sensor data collected by other sensors of the wearable device may also be sent to the data relay after being stored for a certain time or after being stored to a certain data amount. For example, for an acceleration sensor in the wearable device, the acceleration sensor can collect sensor data of a falling infant and send the sensor data to the data relay in time, and can also collect sensing data of normal body movement of the infant such as normal turning over at any time.

It should be noted that the system for monitoring the state of the infant provided by the present specification can be applied to a variety of scenarios, for example, can be applied to a scenario in which a family cares the infant, the wearable device is worn on the infant, and the data relay is placed in a suitable location such as a bedroom or a living room at home, so that a parent or a caregiver can timely know about an emergency sent by the infant through a client installed in the terminal, thereby timely returning to the infant to care for the infant.

For another example, the system may also be used in a scene of a nursery center, the wearable device is also worn on the body of an infant, and the data relay may be placed in a corridor or other suitable position of the nursery center, so that when an emergency occurs to the infant, a caregiver located at a nursing and monitoring station of the nursery center may be timely notified, so that the caregiver may appear around the infant in time to take care of the infant in the emergency. In this scenario, the terminal for receiving the event information may be a computer or other device installed in the monitoring station. Of course, the system may also be applied in other scenarios, such as hospitals, etc., and will not be illustrated in detail here.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually manufacturing an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development, but the original code before compiling is also written in a specific Programming Language, which is called Hardware Description Language (HDL), and the HDL is not only one kind but many kinds, such as abll (Advanced boot Expression Language), AHDL (alternate hard Description Language), traffic, CUPL (computer universal Programming Language), HDCal (Java hard Description Language), lava, lola, HDL, PALASM, software, rhydl (Hardware Description Language), and vhul-Language (vhyg-Language), which is currently used in the field. It will also be apparent to those skilled in the art that hardware circuitry for implementing the logical method flows can be readily obtained by a mere need to program the method flows with some of the hardware description languages described above and into an integrated circuit.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be regarded as a hardware component and the means for performing the various functions included therein may also be regarded as structures within the hardware component.
