Description

Method and apparatus for determining the minimum time of departure from a smartphone-based residence}

The present invention relates to a smart phone-based minimum time residence departure determination, and more particularly, to a smart phone-based minimum time residence departure determination method and apparatus, which is faster and more reliable than GPS without additional equipment.

Recently, due to the COVID-19 outbreak, self-isolation management is on the rise. Self-isolation means that when an infectious disease or virus spreads, when an infection is suspected or there is not enough room for treatment, a notification is issued to a person who has been confirmed but is still mild, and the person who receives the notification isolates himself or herself only at home in accordance with the rules of the health authorities. have to do Therefore, through self-isolation, contact with other people is minimized to prevent the spread of the virus and to perform quarantine smoothly.

However, the self-isolation safety protection app based on the existing smart phone uses GPS to determine the departure of residence when leaving the residence. In the case of GPS, it is basically aimed at outdoors where satellite reception is possible, and even in the case of outdoors, location detection time varies depending on the state of the GPS. For example, in the case of a cold start, a location detection time of 1 to 2 minutes is required, which can be detected after moving 70 to 140 m during outdoor walking. And in the case of a worm start, it takes about 10 to 30 seconds to detect it, and when moving outdoors, it can be detected after moving 15 to 3 m, and finally, in the case of a hot start, it takes about 3 to 10 seconds. Detection time is required, and when moving outdoors on foot, detection is made after 5 to 15 m, and except for hot start, a faster and more reliable dwelling departure determination technology than GPS is required.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, the terms or words used in the present specification and claims should not be construed as being limited to conventional or dictionary meanings, and the inventor should properly understand the concept of the term in order to best describe his invention. Based on the principle that it can be defined, it should be interpreted as meaning and concept consistent with the technical idea of the present invention. Therefore, the configuration shown in the embodiments and drawings described in the present specification is only the most preferred embodiment of the present invention and does not represent all of the technical spirit of the present invention, so at the time of the present application, various It should be understood that there may be equivalents and variations.

1 is a flowchart for performing a method for determining departure from residence for a minimum time based on a smartphone according to the present invention.

First, the user's residence information is input (S100). Here, the residence information means a residence address, type of residence, and a residential floor, and when a residence address is input from the user, the central coordinate of the received residence address lot number is regarded as the user's residence area. At this time, using the last location in the smartphone, such as GPS, is compared with the entered residential area to check whether the input is normal. However, if the difference between the address and the last location is large, the user is encouraged to proceed with the input again after moving to the residence to receive the user's accurate residence information. The type of residence can be classified into the type of residence, and the classification criteria can be broadly classified into the apartment house type and the detached house type, and the apartment house can be classified into the staircase type and the corridor type. In addition, detached houses can be classified into those with a yard and those without a yard. Here, apartment houses include villas, hotels, and officetels, including apartments, and other gosiwons and studios can be classified separately. Meanwhile, the classification criteria are not limited thereto and can be arbitrarily set by applying various criteria.

Thereafter, the residence departure determination process is performed by applying the residence departure determination reference value set according to the pre-classified residence type (S200). The residence departure determination process ( S200 ) will be described later in more detail with reference to FIGS. 2 to 5 .

The reference value for determining departure from residence set according to the type of residence is, for example, in the case of a single-family house with a yard and a first floor, the minimum value of the distance between the center coordinate of the residence lot number and the center coordinate of the adjacent lot number is multiplied by 0.7, so it is set as the maximum number of steps and set to impossible to update and set as a reference value. As another example, in the case of an apartment, stair-type, and 5th floor, the maximum number of steps is set to 5, and the departure is set when the elevation change lasts for 2 seconds or more. Refer to the following [Table 1] for information on the departure determination criteria according to the pre-classified residence type.

[Table 1]

Here, the maximum number of steps is the number of steps (eg, 1 step = 0.7 m) corresponding to the maximum travel distance for departure determination, and the atmospheric pressure change time means the duration for which the atmospheric pressure rises or falls due to taking the stairs or elevator.

Then, the result of leaving the residence is output through the process performed in step S200 (S300). Here, the output can transmit information notifying the user of departure from the residence, and when GPS is received, location tracking is performed to confirm the user's departure from the residence.

2 to 5 are flowcharts illustrating an embodiment in which a residence departure determination process is performed in the method for determining departure from residence for a minimum time based on a smartphone according to FIG. 1 .

First, the present invention according to FIGS. 2 to 5 is based on a smartphone, and the smartphone is equipped with various sensors, such as an inertial sensor and a barometric pressure sensor, including GPS, and uses them. This is done by generating a pattern fingerprint for The fingerprint pattern is formed by collecting the minimum (Min) and maximum (Max) values of the signal strength (RSSI) for each UUID (BSSID) during scanning.

Here, the first embodiment is a case where there is no radio wave pattern and barometric pressure sensor, and is a method of determining departure by limiting the maximum number of steps using an inertial sensor. First, the PDR engine is driven using the inertial sensor and the number of steps (N) Count (S210).

Then, it is checked whether there is a direction change (S212), and if there is a direction change, the number of steps is set back to 0 (S211), and step S210 is performed again. On the other hand, if there is no direction change, it is checked whether the maximum number of steps in the step pattern is greater than the reference value by comparing it with the initial departure determination reference value (N) according to the dwelling type presented in [Table 1] (S214).

As a result of the check (S214), if it is greater than the reference value, it is determined as a departure from the residence (S290), and if it is not greater than the reference value, step S210 is performed again.

Here, the second embodiment is a case in which there is a radio wave pattern using Bluetooth scan but no air pressure sensor, and it is a method for more accurate departure determination by applying a radio wave pattern through Bluetooth scan while restricting the maximum number of steps using an inertial sensor. , First, the PDR engine is driven using the inertial sensor and the number of steps (N) is counted (S210).

Then, it is checked whether there is a direction change (S212), and if there is a direction change, the number of steps is set back to 0 (S211), and step S210 is performed again. On the other hand, if there is no direction change, a Bluetooth (BLE) scan is performed (S213).

After the Bluetooth scan is performed (S213), it is checked whether the maximum number of steps in the step pattern is greater than the reference value N by comparing it with the initial departure determination reference value N according to the type of residence presented in [Table 1] (S214).

As a result of the check (S214), if it is not greater than the reference value (N), the minimum and maximum values of the Bluetooth beacon strength in the propagation pattern are updated (S215), and step S210 is performed again. On the other hand, if the check result (S214) is greater than the reference value (N), it is checked whether the intensity of the Bluetooth beacon is smaller than the maximum value and greater than the minimum value (S216).

As a result of checking (S216), if the strength of the Bluetooth beacon is less than the maximum value and greater than the minimum value, the maximum number of steps in the radio wave pattern is reset to the reference value (N) (S217), and this reference value (N) is the maximum number of steps in the step pattern Step S214 is performed to check whether it is greater than

On the other hand, as a result of the check (S216), if the intensity of the Bluetooth beacon is less than the maximum value and not greater than the minimum value, it is determined as a departure from the residence (S290).

In addition, it is checked whether the atmospheric pressure change time through the barometer value extracted in step S220 is greater than the reference value (A seconds) (S221). As a result of the check (S221), if the atmospheric pressure change time is less than the reference value (A seconds), step S220 is performed again.

Then, as a result of the check ( S212 ), if there is no direction change, it is checked whether the maximum number of steps in the step pattern is greater than the reference value (N) (S214), and if the maximum number of steps is not greater than the reference value (N), step S210 is performed again.

And, as a result of the check (S214), when the maximum number of steps is greater than the reference value (N) and the atmospheric pressure change time is greater than the reference value (A seconds), it is determined as leaving the residence (S290).

Here, the fourth embodiment is a case where there is a radio wave pattern using Bluetooth scan and an air pressure sensor. The first and second embodiments are performed by using the air pressure sensor and applying the radio wave pattern through Bluetooth scan while limiting the maximum number of steps by using the inertial sensor. And as a method for more accurate residence departure determination than the third embodiment, first, the PDR engine is driven using the inertial sensor to count the number of steps (N) (S210), and the atmospheric pressure change time is N/A (Not Applicable). If not, the barometer value is also extracted (S220).

In addition, it is checked whether the atmospheric pressure change time through the barometer value extracted in step S220 is greater than the reference value (A seconds) (S221). As a result of the check (S221), if the atmospheric pressure change time is less than the reference value (A seconds), step S220 is performed again.

And, as a result of the previous confirmation (S212, S221), when there is no direction change and the atmospheric pressure change time is greater than the reference value (A seconds), a Bluetooth (BLE) scan is performed (S213).

After the Bluetooth scan is performed (S213), it is checked whether the maximum number of steps in the step pattern is greater than the reference value by comparing it with the initial departure determination reference value (N) according to the type of residence presented in [Table 1] (S214).

As a result of the check, if it is not greater than the reference value, the minimum and maximum values of the Bluetooth beacon strength in the propagation pattern are updated (S215), and step S210 is performed again. On the other hand, if the check result (S214) is greater than the reference value, it is checked whether the intensity of the Bluetooth beacon is smaller than the maximum value and greater than the minimum value (S216).
