The present invention relates to a method for preventing falling-out by providing information on the left-out member to a leader of a meeting using location information, speed information, or acceleration information of each member's mobile phone when members of a meeting move. The existing location information service measures the location information of one mobile phone and provides an additional service using the measured location information. There was an insufficient point in implementing the present invention for measuring the distance and path between each mobile phone and giving a warning when it deviates from a certain level.

And in the above embodiment, connecting a voice call, a video call, a text message, a voice message or a video message from the mobile phone of the meeting leader to the mobile phone of the missing member (step S11); further includes

As described above, the method of preventing the falling-out of meeting members including the meeting members' mobile phones, the meeting leader's mobile phones and the central server is the distance between each meeting member using the location information of each meeting member's mobile phone when a meeting including several members moves. If the distance exceeds a certain distance by measuring , a dropout message is transmitted to the meeting leader's mobile phone or the meeting leader's mobile phone and the straggler's mobile phone, thereby preventing the meeting member from falling behind.

Therefore, the definition should be made based on the content throughout this specification.

1 is a network configuration diagram for implementing a method and system for preventing a member from falling behind. Referring to FIG. 1 , a network configuration diagram for implementing a method and system for preventing a dropout of a meeting member includes a central server 110 and mobile phones 130 of the meeting members, and the central server 110 and mobile phones of the meeting members ( 130), the mobile communication network 120 is used. As the mobile communication network, GSM, CDMA, WCDMA, LTE and 5G mobile communication networks may be used. Among the mobile phones of the meeting members, there is a mobile phone 140 of the meeting leader.

2 is a cell phone screen of a meeting leader and a meeting member according to an embodiment. When the meeting leader creates a meeting, a corresponding QR code is generated. (210) When the user selects a desired meeting in the mobile phone app or takes a QR code such as an external signboard (220), he joins the meeting. , become a member of the group. When a user joins the meeting, anonymity is guaranteed because no personal information is entered. 230 is a diagram illustrating a mobile phone of a meeting leader. The meeting leader's own location and meeting members' locations are received from the central server and displayed on the meeting leader's mobile phone. 240 is a diagram showing that a dropout message is received when any member of the meeting members is outside the dropout allowable range, that is, when a dropout member occurs.

3 shows the concept of the allowable fallout range P(x,,y) in consideration of the reference position value F(x,y) (310) and the set dispersion intensity s (320) of the group.

The dispersion intensity s (320) is a value indicating the degree of dispersion of the group member positions allowed based on the reference position value F (x, y) (310) of the group. In one embodiment, the dispersion strength s 320 is initially set arbitrarily by the meeting leader. First, due to the nature of the meeting, the group leader chooses the form of dispersion. The form of dispersion may be a dense 910, a linear 920, a scattering 930, etc. (FIG. 9) In the dense type, the members of the group maintain a circular shape and the distribution is even, and the linear It is a form with a long line, and the dispersed type may have an atypical form.

Dispersion strength s (320) may allow input of a predetermined value according to the degree of allowable dispersion. The initial dispersion intensity value is regarded as no movement of the group members, and the dispersion intensity can be determined by reflecting only the distance between the members. For example, if the value of s is set to 5, it can be calculated as s * 10 m and set as having members dispersed within a radius of 50 m.

When the members of the meeting room move, the leader may adjust the dispersion strength s (320) on the reader's terminal in order to set the allowable fallout range P(x,y) (330) between the members. Here, the allowable dropout range P(x,y) 330 may be defined as the maximum distance that each member of a specific group can be separated from all members of the group. For the initial dispersion intensity s (320), a value between 0 and 100 can be input, and if a value of '0' is input, there is no limit to the allowable fallout range P(x,y) (330). (i.e., the alarm does not sound)

When a motion to further increase is taken when the dispersion intensity s is '100' (the initial maximum dispersion intensity), the maximum value of the dispersion intensity is (the previous maximum value). X 2), the set value range is widened, and it becomes a group with a more detailed and reinforced fallout tolerance P(x,y).

When a motion to further reduce the dispersion intensity s is taken in the state of '1' (the initial minimum dispersion intensity), the maximum value is reset to (previous maximum value X 2), the set value range is widened, and the current set value is that of the initial set value. As it doubles, it becomes a group with a more relaxed dropout tolerance P(x,y).

If there is no previously set variance intensity value, it is also possible to calculate the allowable dropout range P(x,y) (330) of the group with the initially set variance intensity value. The initial fallout allowable range P(x,y) 330 may be obtained by the following equation as an example.

Initial fallout tolerance P(x,y) = s X θ X D

where, s: initial dispersion intensity

θ : parameter

D : variance value among members

The reference position value F(x,y) 310 of the group is a value representing the position of the meeting members, and in other words, it can be viewed as an average position value and a central position value. As an embodiment, the reference position value F(x,y) 310 of the group can be obtained as follows.

Reference position value F(x. y) = (reference position latitude value F(x), reference position longitude value F(y))

Base location latitude value F(x) = (∑All members latitude value(x)- Maximum latitude value Max(x)- Minimum latitude value Min(x) ) ÷ (Total members - 2)

Standard location hardness value F(y) = (∑ All members hardness value (y)- Maximum hardness value Max(y)- Minimum hardness value Min(y) ) ÷ (Total members - 2)

And the parameter θ is a kind of weight value multiplied to adjust the dispersion intensity s. And the variance value D between the members is a value corresponding to a value representing the deviation between the members with respect to the average value of the positions between the members.

The allowable fallout range P (x, y) 330 of the meeting is the central server 110 in consideration of the reference position value F (x, y) 310, the dispersion strength s 320, and the parameter θ of the meeting. ) is calculated.

5 is a stray tolerance range P(x, y) It is a diagram showing the concept of calculating (320). The predicted meeting reference position value F'(x,y) 510 may calculate the meeting reference position value after a predetermined time in consideration of the position information, speed information, and acceleration information transmitted from the mobile phones of the meeting members to the central server. For example, after obtaining the displacement vector value w using the location information, velocity information, and acceleration information of the meeting members collected in a predetermined time period immediately before the reference position value of the current meeting, the meeting member after a predetermined time period from the current time It is possible to estimate the standard location value of their gathering. In this case, the displacement vector value w (520) of the meeting reference position value may be defined as follows.

Prediction meeting reference position value F'(x,y) = current meeting reference position value F(x,y) + displacement vector value w

The central server calculates the allowable fallout range P(x,y) (330) in consideration of the meeting reference position value F(x,y) (310), the displacement vector value w (520), and the set dispersion intensity s (320) can do. Here, the shape of the allowable fallout range P(x,y) will generally vary according to the magnitude and direction of the displacement vector value w (520).

With reference to FIG. 5, the allowable fallout range in consideration of the displacement vector value of the reference position value of the group will be described as follows. In an exemplary embodiment, the allowable fallout range may be reset by reflecting the vector value w 520 in the fallout allowable range determined as the reference position value of the current group.

Here, the displacement vector value w (520) of the reference position value of the group can be calculated in consideration of the moving path form (FIG. 10) and the moving speed form (FIGS. 11a, 11b) of the group.

The reference position value of the assembly displacement vector value: w

Reference position value of current meeting: F(x. y)

Reference position value of the adjusted prediction group: F'(x, y) = F(x, y) + w

Dispersion strength: s

Parameter: θ

When defining

The adjusted fallout tolerance P(x, y) can be calculated from the following equation.

√(P(x) - F(x)) ² + (P(y) - F(y)) ² = θ X s - √((P(x) + (F'(x) + F(x)) )/2) ² + (P(y) + (F'(y) + F(y))/2) ²

When judging whether a member is a fallout based on the allowable fallout range in the standard location value F(x, y) of the group, the location value M(x, y) of each member is if P(x, y) ∋ M( x, y), it is judged not to be a failure.

6 is another embodiment in consideration of the displacement vector value w (520) between the meeting reference position value F (x, y) (310) and the predicted meeting reference position value F '(x, y) (510), the stray range P It is a flowchart of a fall-out prevention method for calculating (x,y) (320). In addition to the method of preventing falling-out of meeting members according to the embodiment (FIG. 4), in the embodiment, the central server calculates the tolerance of falling-out in step S4 and when the meeting members move, the current location of the meeting members; calculating a displacement vector value (w) of the reference position value of the current meeting and the reference position value of the meeting predicted after a predetermined time in consideration of the moving speed and the moving acceleration (step S7); and resetting, by the central server, the allowable fallout range in consideration of the displacement vector value (w) calculated in step S7 (step S8); further includes

7 is a diagram illustrating the concept of resetting the dispersion intensity s' 720 based on the existing dispersion intensity s. First, it is determined whether there is an existing set value of the dispersion intensity s. (Step S9) If the set value of the existing dispersion intensity s does not exist, the group leader calculates the allowable dropout range in consideration of the dispersion intensity s set in step S1. (Step S4) However, if there is an existing dispersion intensity setting value, the step of re-adjusting the dispersion intensity s' (720) is performed. (Step S10) In order to readjust the dispersion intensity s' (720), the displacement vector value w (520) of the reference position value of the group, the surrounding topographic indices e1, e2 (710-1, 710-2), and the current group Adjust in consideration of the variance value D (not shown in this figure) for the position value of . As an example, the readjusted dispersion intensity s' can be obtained as follows.

s’ = θ' * s

θ' = θ * f(D, w, e)

Here, each variable is as follows.

s : Existing dispersion strength (310)

s’: adjusted dispersion strength (720)

θ : existing parameter

θ' : new parameter

D: Variance of current meeting member positions (deviation from the average of current meeting members’ position values)

w: Gathering reference position value displacement vector value (520)

e: surrounding topographical index (710-1, 710-2)

Here, θ is a kind of weight value multiplied to adjust the dispersion intensity s as described above. The adjusted parameter θ' is the previous parameter θ with the current group member position variance value D, the meeting reference position value displacement vector value w (520), and the surrounding topographical indexes e1, e2 (720-1, 720-2) as variables. It can be a value multiplied by a function f. The surrounding topographical index e may be defined as a value of probability that a member of the group exists in the topography by changing its value depending on whether the topography is a road, a forest, a paddy field, or a field. That is, roads (sidewalks), etc., have a high probability of having members of the group, so the value of the surrounding topographic index e may increase, and in the case of forests, the probability of the members of the group is low and the value of the surrounding topographical index e may decrease.

For example, the surrounding topographical state value e may be input as follows after imposing a differential value for each area on a map divided into areas such as roads, buildings, and mountains.

Ex) 10 car roads, 9 bike paths, 8 sidewalks, 7 forests, 6 mountains, 3 buildings, 1 rough terrain.

When the stray tolerance value in the moving direction is included in another section with a rare probability that the member of the group exists in the section selected during movement, it is also possible to correct the vector value by the difference value of the other section. That is, if the newly moved meeting reference location in FIG. 7 is outside the preset road section by e1 (710-1), the probability that the meeting member exists in the section is extremely low because the portion corresponding to section e1 is not a road. . Accordingly, by correcting the displacement vector value by e2 (710-2) (that is, the vector value may be corrected as w - e) corresponding to this, a new gathering reference position value may be predicted. Through this process, the meeting leader can determine whether or not members of the meeting are left behind according to the finely adjusted dropout area.

As an example, FIG. 8 shows the fallout tolerance range P' (x, y) ( 730) is a flowchart of a fall-out prevention method. In addition to the method for preventing falling-out of meeting members according to the embodiment (Fig. 6), in the embodiment, when the central server calculates the allowable fall-out range in step S4, the central server checks whether the previous distribution strength setting value exists. determining whether or not (step S9); and the central server considers the previous dispersion intensity setting value (s), the displacement vector value (w) calculated in the step S7, and the surrounding terrain index (e), when there is a previous dispersion intensity setting value in step S9. to reset the dispersion strength (s') (step S10); further includes

In the method for preventing a meeting member from falling out according to an embodiment, in the embodiment, the central server in step S6 may transmit a missed message not only to the mobile phone of the meeting leader but also to the mobile phone of the falling member. In this case, it is possible to enable the straggled member to quickly join the meeting by transmitting the straggled message to the mobile phone of the straggled member as well. And in the above embodiment, connecting a voice call, a video call, a text message, a voice message or a video message from the mobile phone of the meeting leader to the mobile phone of the missing member (step S11); may further include.
