In addition, the service target setter 330 searches for a smart device in the area generated by the service area generator 320 and sets a smart device to provide an amber warning service based on the location information reflecting the above-described location change. do. That is, the service target setter 330 may determine which smart device among the collected smart devices to provide the amber alert service.

The service target setter 330 sets a smart device to provide a service based on the location information reflecting the location change, and there may be some error between the location information reflecting the location change and the actual location of the smart device. . However, since the amber warning system according to the present invention may be a main purpose to quickly inform as many people as possible of emergency situations, such as indiscriminate terrorism, violent crime, disasters, disasters, etc., the smart device within the above-described area to search and set It is not a big problem to use the positional information having a certain error at the time.

For reference, the search criteria for searching for a smart device within the above-described area is not particularly limited. For example, the service target setter 330 may search for a smart device having a dedicated application for providing an amber alert service according to the present invention, and set the found smart device as a smart device to provide an amber alert service.

The transmitter 340 disconnects after transmitting data for providing the amber alert service to all the smart devices or some smart devices set by the service target setter 330 based on the device information. After data transmission, the communication is disconnected to reduce the traffic, and the socket is opened for socket communication only when a connection request is made.

In this case, the data for providing the amber alert service may be data stored in the memory 360 to correspond to the amber alert situation, and may be provided through an I / O device 370 such as a wired / wireless keyboard, a virtual keyboard, a mouse, a touch keypad, or the like. It may be input data. Such an input operation is preferably performed by a worker of a country, a public institution, or a group in which the amber warning service supply device 300 according to each embodiment of the present invention is disposed.

Referring to FIG. 11, the operations of the receiver 310, the service area generator 320, the service target setter 330, and the transmitter 340 described above will be briefly described as follows. FIG. 11 is a flowchart illustrating a process of operating the amber warning service supply device of FIG. 8.

The service target setter 330 may search for location information of the plurality of smart devices collected through the receiver 310 (S1110). The service target setter 330 performs the task of classifying the location information of each smart device according to whether it is included in the area set by the service area generator 320 (S1120). Referring to the figure next to the flowchart, the service area generator 320 sets an area B within a predetermined radius from the center point A, longitude / latitude = 127.6 / 44.11 as an area for providing the amber warning service. The service target setter 330 may be divided into smart devices 100, 102, and 104 within a set area and smart devices 106 and 108 outside a set area by using location information of each smart device. Subsequently, the transmitter 340 connects to the smart devices 100, 102, 104 through the IP information and the port information of the smart devices 100, 102, 104 set by the service target setter 330. The transmitter 340 transmits data for providing an amber alert service including emergency notification contents to the smart device 100, 102, 104.

In this case, the transmitter 340 may transmit data for providing the amber alert service through a specific application that is pre-loaded in all or some smart devices. For example, the transmitter 340 may be a plug-in or a plug-in through a mobile messenger application such as KakaoTalk, My People, Chat On, Line, Tick Talk, or a dedicated application for providing an amber alert service. It can provide data for amber alert service in the form of API (Application Programming Interface).

With respect to the criteria for deciding whether to transmit the data for providing the Amber Alert service to all of the smart devices set by the service target setter 330 or to transmit such data to a part, the service target setting. The number of smart devices set by the device 330 may be used as a reference.

In other words, the transmitter 340 transmits data for providing the amber warning service to all the smart devices when the number of the smart devices set by the service target setter 330 is less than the first reference value. When the number of smart devices set by the service target setter 330 is greater than or equal to a first reference value, data for providing an amber alert service may be transmitted to some smart devices.

In addition, among the smart devices set by the service target setter 330, a criterion for selecting and determining some smart devices to which data for amber warning service is to be transmitted is additionally needed.

In this regard, the amber alert service supply apparatus 300 according to another embodiment of the present invention may include some target determiners as well as a receiver 310, a service area generator 320, a service target setter 330, and a transmitter 340. 350 may be further included. That is, the some target determiner 350 is a configuration for a criterion for determining some smart devices among all the smart devices set by the service target setter 330 described above.

Some target determiner 350 operates when the number of smart devices set by the service target setter 330 is equal to or greater than a first preset reference value, and determines some smart devices based on the preset criteria.

In detail, when some target determiner 350 operates, the service area generator 320 repeatedly performs an operation of dividing an area where an amber alert service is provided. In particular, the dividing operation is performed until the number of smart devices in each division area generated as a result of the dividing operation is smaller than the first reference value. In addition, a grid search algorithm may be modified and applied to the service area generator 320.

In this case, the some target determiner 350 determines the smart device by the second reference value preset for each of the divided regions generated by the service region generator 320, and the transmitter 340 is determined by the some target determiner 350. Some smart devices send data to provide amber alert services.

FIG. 12 is a diagram illustrating an example in which a service area generator and some target determiners operate in the amber alert service supply device of FIG. 8.

When some target determiner 350 operates, the service area generator 320 may generate the divided areas A, B, C, and D as shown in FIG. If the number of smart devices in the C partition among the A, B, C, and D partitions is equal to or greater than the first reference value, the service area generator 320 may divide the C partition again.

Some target determiner 350 determines the smart device by the second reference value preset for the A, B, C, D partition area in which there are fewer smart devices than the first reference value. If the second preset reference value is 2, two smart devices 100 and 102 may be determined among a plurality of smart devices in the B partitioned area.

In particular, when the second reference value is 1, the some object determiner 350 may determine each smart device located at the position nearest to the center of each divided area as some smart devices. That is, each smart device (100, 100 ', 100 ", 100"') that is located closest to the centers of a, b, c, and d partitions a, b, c, and d may be determined as some smart devices. have.

In this case, the data for providing the amber warning service may include IP information of the smart device in each partition, port information of the smart device in each partition, and event information generating an amber warning condition. However, IP information and port information may vary depending on which partition the smart devices are located in.

For example, the transmitter 340 transmits data for providing an amber alert service to the smart device 100 located closest to b, which is the center of the B partition. The data for providing the amber alert service transmitted to the smart device 100 in the B partition includes IP information of the other smart devices 102 and 104 in the B partition, and other smart devices 102 and 104 in the B partition. ) May include port information and event information for generating an amber warning situation.

Hereinafter, with reference to FIGS. 13 and 14 with respect to operations performed by the service area generator 320 and some target determiner 350 in the amber warning service supply device 300 according to another embodiment of the present invention. do. FIG. 13 is a diagram illustrating a process in which some smart devices are determined by some target determiners in the amber alert service supply device of FIG. 8, and FIG. 14 is a divided region by a service area generator in the amber alert service supply device of FIG. 8. This is a view for explaining the process of generating.

In step ① of FIG. 13, as an example, it may be assumed that there are 300 smart devices set by the service target setter 330 in the area extracted and set by the service region generator 320. As an example, it may be assumed that the first preset reference value is 100 and the second preset reference value is one.

Since the smart device set by the service target setter 330 is 100 or more in step ②, some target determiner 350 operates to determine some smart devices to receive the data for providing the amber alert service. If the number of smart devices set by the service target setter 330 is less than 100 in step ②, the transmitter 340 may directly transmit data for providing the amber warning service to all the smart devices. That is, even if the first reference value is directly processed by the amber alert service supply device 300, it is preferable that the first reference value is preset to a value that does not cause any traffic or power load problem in particular.

When some target determiner 350 operates, the service area generator 320 repeatedly divides an area where an amber alert service is provided. As a result of the dividing operation on the region, a divided region such as A, B, C, or D is generated. It can be seen that there are 90, 50, 40, and 120 smart device users in the divided areas A, B, C, and D, respectively, which can be determined using location information of the smart device.

In step ③, the number of smart devices existing in the partitions A, B, and C is smaller than the first preset reference value, and the number of smart devices existing in the partition D is still greater than or equal to the preset first reference value. You can see that. The service area generator 320 repeatedly performs the partitioning operation on the partition area D until the number of smart devices in the partition area D is less than 100. Some target determiner 350 may determine, as some smart devices, one smart device (second reference value) at a position closest to each center of the divided areas A, B, and C.

In step ④, the transmitter 340 transmits data for providing an amber alert service to some smart devices determined in step ③. In this case, the data for providing the amber alert service may include IP information, port information, and event information for generating an amber alert situation of another smart device in each partition.

As described above with reference to FIG. 2, the data for providing the amber alert service includes IP information of the other smart devices 102 and 104 and port information of the other smart devices 102 and 104 and the amber alert service supply device 300. ), The smart device 100 receiving such data may be some smart devices determined by some target determiner 350. Therefore, the smart device 100 serving as a server is based on the IP information of the other smart devices 102 and 104 and the port information of the other smart devices 102 and 104 to the other smart devices 102 and 104 as clients. Socket communication can be performed, and data for providing an amber alert service can be transmitted.

In this manner, since the amber warning service supply device 300 according to each embodiment of the present invention transmits the data for providing the amber warning service to the smart device, the amber warning service supply device 300 has a traffic or power load problem. You can send data to multiple smart devices without That is, the amber alert service supply device 300 does not directly transmit data to all smart devices, but transmits data to some smart devices determined by some target determiner 350. For the other smart devices, some smart devices transmit data. As a result, it is possible to increase the transmission capability of the amber warning service supply device 300 according to each embodiment of the present invention to the maximum, and to minimize the cost required to install the amber warning service supply device 300 when the service environment is actually established. Can be.

In step ⑤, the service area generator 320 repeatedly performs the partitioning operation on the partition area D until the number of smart devices in the partition area D is less than 100. It can be seen that there are 10, 5, 25, and 80 smart device users in the partitions D-1, D-2, D-3, and D-4, respectively. It can be seen that the number of smart devices in each partitioned area is less than 100. That is, the service area generator 320 may no longer perform the dividing operation.

Step ⑥ can be the same process as step ③. Some target determiner 350 may determine, as some smart devices, one smart device (second reference value) at a position closest to each center of the partitions D-1, D-2, D-3, and D-4. have.

In step ⑦, the same process as in step ④ can occur. The transmitter 340 transmits data for providing an amber alert service to some smart devices determined in step ⑥. In this case, the data for providing the amber alert service may include IP information, port information, and event information for generating an amber alert situation of another smart device in each partition. Some smart devices may transmit data for providing an amber alert service to other smart devices in each partition based on IP information and port information of other smart devices in each partition. If the event information causing the amber warning situation is in the form of a URL, the packet size required for data transmission from some smart devices to other smart devices may be very small.

⑧ Referring to step ⑧, the amber alert service supply device 300 according to each embodiment of the present invention consequently provides data for providing amber alert service only to some of 7 smart devices among 300 smart devices through the transmitter 340. It can be seen that it transmits. The remaining 293 smart devices may receive data for providing an amber alert service through socket communication by a smart device serving as seven servers. By applying such a high-volume traffic processing technology, the amber warning service supply apparatus 300 according to each embodiment of the present invention can transmit data to a plurality of smart devices without traffic or power load problems.

As illustrated in FIG. 14, four division regions 1410 may be generated when the division by the service region generator 320 is performed once. The divided region 1420 at the upper right is further divided into four, and the divided region 1430 at the lower left is further divided into four and some portions are further divided into four. The divided area 1440 on the lower right is divided into 16 parts (1450), and then a part of the divided areas 1440 is further divided into 4 parts (1460). One area that is initially generated is divided into a total of 40 divided areas by the service area generator 320, and the number of smart devices within the 40 divided areas is less than the first reference value. Some target determiner 350 determines a smart device as a predetermined second reference value among the smart devices in each partition as some smart devices, and the transmitter 340 provides data for providing the amber alert service to the smart devices. Send.

By using the amber warning service supply apparatus according to each embodiment of the present invention described above, it is possible to use the data communication network and the existing system as much as possible to reduce the cost of actual implementation, and to discriminate against terrorism, violent crime, disaster, disaster In case of an emergency such as an accident, many people can provide services that can help the public.

The above dividing operation is repeatedly performed until the number of times is less than the first reference value.

If the number of smart devices in the divided area is less than the first preset reference value (Yes), the smart devices corresponding to the preset second reference value are determined for each divided area (S1546), and the determined smart devices are partially smart. Decide on the equipment.

In this case, when the second preset reference value is 1, one smart device at the position closest to the center of each partition is determined one by one, and the determined smart device is determined as some smart devices to transmit the data for providing the amber warning service.
