Description

Altitude sensor-based outing detection device and method

The present invention relates to an altitude sensor-based outing detection technology, and more particularly, to an altitude sensor-based outing detection device and method capable of quickly and accurately detecting a user's going out through changes in atmospheric pressure and temperature using an altitude sensor will be.

Currently, global navigation satellite system (GPS) and WiFi-based positioning system development and service are being actively developed. As for the system using GPS, a simple positioning system that calculates one's location using only the GPS itself and a location tracking system linking WiFi/mobile communication network are being developed, and are being used in various fields. A system using WiFi provides a positioning service indoors where GPS does not reach. When GPS and WiFi/mobile communication networks are linked, the accuracy of indoor and outdoor location information can be improved.

For example, the location tracking system is used to identify the scope of action for the prevention, protection and management of disappearance of dementia patients and children, and to provide notifications to guardians and managers when entering or leaving a certain area.

On the other hand, guardians or managers need to know immediately when they are outside in order to respond quickly before objects that need protection, such as the elderly, children, or pets, are exposed to danger.

Existing outing detection using GPS uses the GPS mounted on the smartphone or a dedicated GPS watch, which consumes a lot of the battery of the smartphone and the dedicated watch. There is a problem that it is difficult to check immediately after going out because there is a risk of doing it indoors, and since the GPS is not available indoors, the user must pass a certain distance after going out to know the location.

Moreover, since the called time takes about 5 minutes to start or restart the GPS, it lacks immediateness, and in a specific area, intermittently and repeatedly GPS location values are received as a bouncing value beyond the original area. Occurs. In the case of a user in an area where such a situation occurs, a malfunction occurs that repeatedly occurs when going out and returning home, which seriously impairs usability.

In the past, an infrared sensor was installed on the front door to detect going out through the door opening, but there is a problem in that the accuracy is significantly lowered to make a judgment about going out by only detecting the door open. For example, when a visitor arrives, if the door is opened and milk is put in, it is detected as an open door and determined to go out.

Korean Patent Publication No. 10-0926239 (November 3, 2009) relates to a user location tracking device using a GPS function, a GPS receiver for receiving satellite information transmitted from a GPS satellite, A microcomputer having a built-in memory storing the area coordinate value and comparing whether the current coordinate value according to the satellite information newly received from the GPS receiver is out of the area coordinate value of the management area based on the area coordinate value, and in the microcomputer As a result of the comparison, a voice output unit that generates an alarm sound when the current coordinate value is out of the zone coordinate value, and a guardian's mobile phone when the current coordinate value in the microcomputer is out of the range of the zone coordinate value The user has left the management zone It is characterized in that it is composed of a long-distance communication unit that wirelessly outputs area departure information for notifying.

Korean Patent Application Laid-Open No. 10-2017-0060572 (June 1, 2017) relates to a push service system through an access event. It detects that a door is opened from indoors to outdoors and wirelessly transmits a door event signal including door identification information. a door lock device that generates, a user terminal that receives the door event signal, checks whether the door event signal is generated from a previously registered door lock device, and transmits an outing event signal through the door identification information; and and a service server that receives an outing event signal and provides a push service to the user terminal.

Here, the user may target the elderly who may be at risk, such as an accident or disappearance, when exposed to the outside, such as the elderly with dementia, infants, and the like, but is not limited thereto, and subjects such as people and pets in need of protection and management are not limited. In an embodiment, the outing detection device 110 may be manufactured to be very small and light so that it can be easily attached to or carried by a user who is an outing detection target. For example, the outing detection device 110 may be implemented in a form that can be simply attached like a sticker or a wearable device that can be worn such as a bracelet, glasses, necklace, watch, ring, or clothes. Here, the going out detection device 110 may detect whether to go out through changes in air pressure and temperature generated when the user moves from indoors to outdoors using an altitude sensor.

The processor 210 may execute a procedure for performing an operation in the process of determining whether to go out for the user wearing the going out detection device 110 based on changes in air pressure and temperature sensed by the altitude sensor 220 . In addition, it is possible to manage the altitude sensor 220 measured throughout the process, and schedule a synchronization time between the atmospheric pressure sensing and the temperature sensing in the altitude sensor 220 . The processor 210 may control the overall operation of the outing detection device 110 , and is electrically connected to the altitude sensor 220 , the memory 230 , the user input/output unit 240 , and the network input/output unit 250 . You can control the flow of data between them. The processor 210 may be implemented as a central processing unit (CPU) of the outing detection device 110 .

The altitude sensor 220 may be implemented as an air pressure sensor such as a digital pressure sensor, and may measure altitude information and temperature information required to detect going out in the going out detection device 110 . For example, the altitude sensor 220 may use a board-mounted pressure sensor HSPPAD042A.

The memory 230 is implemented as a non-volatile memory, such as a solid state drive (SSD) or a hard disk drive (HDD), and may include an auxiliary storage device used to store overall data required for the outing detection device 110, It may include a main memory implemented as a volatile memory such as random access memory (RAM).

Here, the network may be connected to the management server 130 or the guardian/manager terminal 150 through the network input/output unit 250 .

FIG. 3 is a block diagram illustrating a functional configuration of the outing detection device 110 of FIG. 1 .

Referring to FIG. 3 , the going out detection device 110 includes an altitude measuring unit 310 , a temperature measuring unit 320 , an outing determining unit 330 , an outing notification unit 340 , and a control unit 350 .

The altitude measuring unit 310 may measure in real time the altitude of the current space of the user who is the object of going out detection who possesses or wears the going out detection device 110 . In an embodiment, the altitude measurement unit 310 may measure the altitude using an altitude sensor. The altitude sensor is a type of pressure sensor and may measure the altitude of the current location by detecting a change in air pressure according to the difference in altitude. Here, the altitude may be changed according to the environment while the user moves.

The temperature measuring unit 320 may measure in real time the temperature of the current space of the user who is the object of going out detection who possesses or wears the going out detection device 110 . The temperature measuring unit 320 may use a temperature sensor or a temperature measuring function of the altitude sensor used for measuring the altitude.

The altitude measurement unit 310 and the temperature measurement unit 320 may measure the altitude and temperature of the user's current location in real time. In this case, the altitude measurement unit 310 and the temperature measurement unit 320 may synchronize the altitude and the temperature at a predetermined time interval to measure.

The going out determination unit 330 may determine whether the user goes out based on the altitude data and the temperature data respectively measured by the altitude measuring unit 310 and the temperature measuring unit 320 . In an embodiment, the going out determination unit 330 may be equipped with an outing detection algorithm and may determine whether the user goes out by executing the installed outing detection algorithm. Here, the outing determination unit 330 determines the altitude change and temperature change for a predetermined time period with respect to the altitude data and temperature data actually measured by the altitude measurement unit 310 and the temperature measurement unit 320 to determine the movement of the user. It is predictable and can determine whether it is a simple movement indoors or going out from indoors to outdoors.

The going out determination unit 330 may minimize the measurement error by obtaining an average of the actually measured altitude data and temperature data in units of a predetermined time. In an embodiment, the going out determination unit 330 may set a unit average period for obtaining the average altitude value and the average temperature value to be less than the comparison period to quickly detect going out. For example, when the unit average section is set to 10 seconds and the comparison section is set to 1 minute, going out can be detected quickly within 1 minute. The outing determination unit 330 may obtain an altitude difference and a temperature difference by comparing the average altitude and temperature in the current comparison section with the average altitude and temperature in the previous comparison section. Here, the altitude difference and the temperature difference may mean an altitude change and a temperature change according to an environment change while the user moves. That is, rapid elevation changes and temperature changes in the time of the comparison section mean moving to different elevation and pressure environments.

The going out determination unit 330 may determine whether the user goes out by comparing the altitude difference and the temperature difference with respective threshold values. In an embodiment, when the altitude difference is greater than or equal to the first threshold and less than or equal to the second threshold, whether or not to go out may be determined by reflecting the temperature difference, and if the altitude difference is greater than or equal to the second threshold, it may be determined that the user has gone out. Here, the going out determination unit 330 may determine going out by reflecting the indoor environment based on the altitude difference and the temperature difference. For example, the indoor temperature may vary depending on the size, location, and space of the house, and in the case of a multi-story building, an altitude deviation may occur indoors. The going out determination unit 330 may reflect the temperature deviation and altitude deviation that may occur depending on the indoor environment by determining whether to go out by combining the altitude and the temperature. For example, if the height difference in the comparison section is greater than or equal to the first threshold of "100" and less than the second threshold of "200", the outing determination unit 330 may be a simple floor movement indoors. can When the temperature difference is equal to or greater than the third threshold value of "2 degrees", the going out determination unit 330 may determine that the user has gone out from indoors to outdoors. Here, the third threshold may mean a relative deviation of the room temperature. When the temperature difference is less than "2 degrees", the going out determination unit 330 may determine that the altitude change has occurred due to a large movement in the room. If the altitude difference is greater than or equal to the second threshold value of "200", the going out determination unit 330 may determine that there is an abrupt altitude change and determine going out regardless of the temperature difference. The sudden change in altitude greater than or equal to the second threshold may be mainly applied to a case in which a subject to be detected goes out is moved by an elevator in an apartment.

The going out determination unit 330 may apply an exception period to a specific situation when determining going out. In an embodiment, the going out determination unit 330 assumes an uncertain altitude value for the altitude value measured for a certain time when the altitude sensor is "turn-on/turn-off" Therefore, it does not judge whether or not to go out. Here, the outing determination unit 330 may increase the accuracy of the actual measurement data by setting the comparison period time to be relatively long in the first comparison period.

The going out notification unit 340 outputs a notification signal notifying the user going out when the going out determination unit 330 determines that the user is going out. The going out notification unit 340 receives the signal from the going out determination unit 330 and immediately outputs a notification signal. That is, the going out notification unit 340 may output an outing notification signal as soon as the user comes out of the room within the comparison section of the going out determination unit 330 . The outing notification unit 340 may transmit an outing notification signal to the management server 130 and the guardian/manager terminal 150 through the network to notify whether the user goes out.

The control unit 350 controls the overall operation of the going out detection device 110 , and a control flow or data between the altitude measuring unit 310 , the temperature measuring unit 320 , the going out determination unit 330 , and the going out notification unit 340 . You can manage the flow.

FIG. 4 is a flowchart of an altitude sensor-based outing detection process of the going out detection device 110 of FIG. 1 .

In FIG. 4 , the outing detection device 110 synchronizes the altitude and temperature of the space where the user is located through the altitude measurement unit 310 and the temperature measurement unit 320 and measures in real time (step S410 ). In this case, the actually measured altitude data and temperature data may be measured through an altitude sensor built in the wearable type outing detection device 110 worn by the user. The altitude measurement unit 310 may detect the ambient pressure and measure the altitude from the detected air pressure. The temperature measuring unit 310 may measure the ambient temperature by utilizing the temperature measuring function of the altitude sensor, and may measure the temperature by embedding a temperature sensor separately from the altitude sensor in the going out detection device 110 . In this case, the interval at which the actual measurement data is extracted may be changed and set according to the sensitivity of the sensor.

The outing detection device 110 determines whether the user goes out based on the altitude data and temperature data actually measured through the going out determination unit 330 (step S420). The step of determining whether the user goes out is to obtain the average value of the altitude data and the temperature data actually measured during the time of the set unit average section (step S421), and the altitude difference and the temperature difference from the average altitude value and the temperature average value calculated in the previous section are obtained. After (step S422), the user's outing is determined by comparing the altitude difference and the temperature difference with each threshold (step S423). The going out determination unit 330 may accurately determine the user's going out through a rapid altitude change and temperature change by comparing with threshold values within the comparison section time based on the altitude difference and the temperature difference. The going out determination unit 330 may exclude a situation of moving a position indoors through a difference in altitude and a temperature, and may accurately determine whether the user goes out from the room to the outside.

The outing detection device 110 may immediately provide a notification of the user going out to the guardian and the manager when the going out determination unit 330 determines to go out through the going out notification unit 340 (step S430). The outing notification unit 340 immediately transmits an outing notification signal when the user's outing is detected when the outing determination unit 330 determines that the user goes out during the time of the comparison section to notify the guardian/manager terminal 150 of whether the user goes out. can

In FIG. 5 , the altitude sensor-based outing detection device 110 according to an embodiment applies an exception section for a predetermined time of about 2 minutes at the time when the altitude sensor 220 is “turned-on” Accordingly, it is possible to increase the accuracy of going out detection by not using the measurement data that is uncertain at the time when the altitude sensor 220 starts to operate to determine going out. The outing detection device 110 may apply the comparison section in units of about 1 minute from the time when the exception section has elapsed to quickly detect going out as soon as the user goes out. The outing detection device 110 sets a unit average section that is about 1/5 or more less than the comparison section before the comparison section, so that the altitude and temperature measured by the altitude sensor 220 during the unit average section for about 10 seconds are set. average can be obtained. The outing detection device 110 compares the average value of the altitude and temperature obtained within the time of the current comparison section with the average value of the altitude and temperature obtained in the previous comparison section to obtain the altitude difference and temperature difference, and sets the altitude difference and temperature difference to a preset threshold. In comparison with , it is possible to detect the user's outing. Here, the threshold may mean an altitude and a temperature deviation capable of distinguishing indoors and outdoors.

Altitude sensor-based outing detection device and method according to an embodiment can detect only whether going out quickly and accurately through changes in atmospheric pressure and temperature using an altitude sensor, so that the elderly and the infirm, such as the elderly with dementia or infants, and the like without fear of infringing on privacy Parents and managers can quickly find out when pets are going out.
