More specifically, a guard using a smart band to recognize a guard distance in real time by providing a location notification sound corresponding to a distance to a subject of a guard The present invention relates to a distance notification device and method.

A bodyguard is a person whose job is to take care of the safety of others, generally serving as a celebrity, a politician, a state guest or other celebrity, but recently a child, youth or woman As crimes are increasing, the general public increasingly employs bodyguards.

The bodyguards move with the bodyguards to identify and remove all possible threats to the body, thereby protecting the body of the bodyguards from external threats, and the bodyguards can use a variety of bodyguards. It is possible to perform more efficient and safe guard service by using communication equipment for communication between bodyguards when performing group security service as well as self-protection equipment capable of overpowering the other party.

In particular, communication equipment for communication between bodyguards generally uses hands-free radios to freely use both hands due to the nature of the bodywork, wearing a radio body on a top or a belt, and connecting the radio body to the radio body by wire or wirelessly. Wear a microphone to use. This remains at the level of simple voice communications.

Such security communication equipment has a limitation in allowing the user to perform prompt and prompt security work while clearly knowing the current situation.

In order to improve the limitation problem of the security equipment of the simple voice communication level as described above, Korean Patent Laid-Open Publication No. 10-2013-0128786 discloses a 'security system equipped with a video system' as a technology for the conventional security equipment.

However, while the bodyguard may be away from the bodyguards while the bodyguard is in the vicinity of the bodyguard at an airport, terminal or rally or stadium where a large number of people are involved, the bodyguard may be farther away from the body if the situation arises. Failure to do so may occur.

Therefore, it is necessary for the bodyguard to recognize the situation in which the bodyguard is away from the bodyguard in real time. Security equipment equipped with a conventional imaging system has a function of analyzing a photographed image to determine the distance between a subject (guard subject) and a bodyguard (photographer) and displaying the same. However, when the subject is alone, image analysis is performed. Yes, but when you're in the crowd, you can determine the distance by image analysis, and it can be used to the extent that the commanding officer sees it and conveys the order to the nearest bodyguard, rather than the proximity body looking at the display and recognizing the distance.

As a result, with the conventional bodyguards, there is no choice but to visually observe the proximity guards in real time by the way the bodyguards perceive the distance to the subjects, and when it is difficult to completely close the bodyguards, the situation can easily be hidden by people. This can be caused. Therefore, there is a need for escort equipment that can automatically measure the distance between the guard and the subject and notify the guard in real time.

And, it generates a notification sound corresponding to the distance signal generated from the control module 140, characterized in that it comprises a notification output unit 150 for outputting to the ear microphone (120).

The transmission kit 200 may be a basic configuration including only a wireless transmitter for transmitting a distance measuring radio signal, as shown in FIG. 1, having a communication module 210, a control module 220, and a vibration module 230. It may be one configuration.

In addition, the communication module 130 of the portable device 100 may be configured as a radio receiver only for receiving a radio signal of the transmission kit 200 and detecting a reception signal.

In addition, as shown in FIG. 1, the mobile device 100 also includes a communication module 130 for short-range wireless communication, and the calling kit 200 includes a communication module 210 for wireless communication, both of which are wireless. Transmission and reception may be configured to be possible.

Similarly, the control module 140 of the portable apparatus 100 and the control module of the calling kit 200 may also detect the strength of the wireless reception signal, measure the distance, and generate a notification sound corresponding to the distance. The portable device 100 generates a notification sound corresponding to a linear change in distance, and the outgoing kit 200 may drive the vibration module 230 to notify when the distance is greater than or equal to the alarm distance.

In addition, the portable device 100 of the present invention,

The size of the notification sound and the period of generating the beeping sound may be controlled in inverse proportion to the distance away from the calling kit 200. That is, the notification sound may be output to identify the current distance in response to the linear distance change.

In addition, the portable device 100

The notification sound may be controlled by dividing the signal into a plurality of sections by distance based on the received signal strength of the wireless signal, and by setting a different beep size and a beep generation period for each section. That is, the notification sound for each section may be differently set and output as the notification sound for each section of the distance.

In the present invention as described above, the subject to be protected carries the originating kit 200 (A), and the body to carry the portable device 100 (B). The portable device 100 is configured to integrate the distance measuring notification device of the present invention into a radio that is normally carried by bodyguards, that is, a radio module 110 capable of a voice call. The portable apparatus 100 is generally for a voice call between a security center or bodyguards, and typically includes an ear microphone 120 as a hands-free device.

2 is a flowchart illustrating a security distance notification method according to a first embodiment of the present invention.

The portable device 100 carried by the bodyguard performs the step S10 of receiving the radio signal transmitted from the calling kit 200. That is, the portable device 100 receives a radio signal for measuring the distance of the calling kit 200 carried by the body of the guard. The method for receiving a wireless signal may be configured to periodically transmit short-range wireless signals (eg, beacon signals, Bluetooth, Wi-Fi, etc.) from the calling kit 200 or the calling kit 200 from the portable device 100. When the wireless signal request signal is transmitted to the transmission kit 200, there may be a method for transmitting the wireless signal as a response signal.

The portable apparatus 100 measures the received signal strength of the received wireless signal and generates a distance signal corresponding thereto (S20). The distance signal refers to a distance that the user can easily recognize and does not mean an absolute distance. It is known that the strength of the received signal is inversely proportional to the distance assuming that there are no radio signal obstacles in the near field communication.

When the strength of the received signal is measured and a distance signal is generated in response to the received signal strength, a step (S30) of generating a distance notification sound at a sound volume and an output period corresponding to the preset distance signal is performed. The distance notification sound takes a method of increasing the volume of the notification sound and controlling the output period as the distance increases in inverse proportion to the strength of the received signal.

The notification output unit performs the step (S40) of outputting the distance notification sound to the earphone connected to the radio module.

3A to 3C are explanatory diagrams of a guard distance notification of a guard distance notification device according to a first embodiment of the present invention.

As shown in (a) to (c) of FIG. 3, the subject A1 and the bodyguard B1 have a first distance (for example, 3M), a second distance (for example 3-5M), and a third distance (for example 5M or more). In the case of), the distance can be announced by outputting the intermittent sound at a volume and an output period that can be distinguished from each other for each distance. For example, suppose that the buzzer sounds (assuming the buzzer level is 1 to 3) is sounded every 30 seconds when it is within 3M radius as shown in FIG. 3A. When within the radius of 3M-5M, the buzzer sounds at level 2 every 15 seconds, and when the distance is greater than 5M as shown in (c) of FIG. 3, the distance is notified by the buzzer at level 3 every 5 seconds. If the distance is more than 5M or do not receive the wireless signal or if the weakly repeated reception and reception of the wireless signal is to sound the distance alerting alarm level with continuous intermittent sound.

As a result, with the methodology described above, the volume and intermittent sound output period may be linearly inversely proportional to the strength of the wireless signal, and the volume and output period of the notification sound may be varied for each distance section corresponding to the intensity of the wireless signal. Can be. Accordingly, by outputting a distinctive sound for each distance, the body can recognize the distance between the subject and bodyguards in real time.

This method should always be watched for close guards, such as factor guards. However, in general guards, close guards of guards may be burdensome and there may be cases where guards should be guarded at close distances. While moving away from the distance, the distance may be far away. At this time, if the security distance notification method of the present invention is used, the bodyguard can always follow the body of the subject within an appropriate distance.

As described above, the first embodiment of FIG. 1 includes a communication module 130, a control module 140, and a notification output unit for alerting a distance to a radio transceiver module 110 for a voice call for a purpose of a voice call using a general Lydo frequency. 150) is integrally formed. In addition, when the distance is measured by the strength of the radio signal, the notification sound is controlled in inverse proportion to the measured distance and output. In addition, the notification sound is periodically output with the distance measurement so as to know the current state of the distance periodically, the bodyguard can always recognize the distance to the subjects with the alarm sound only. That is, rather than outputting an alarm sound only when the alarm distance is out of the set distance, the alarm sound may be output in response to the change of the war in real time so that the distance to the guarded person can always be recognized.

As shown in FIG. 6.

A security distance notification method for automatically notifying the distance between a plurality of subjects and a plurality of bodyguards,

A local network for wireless communication is formed between a plurality of originating kits 200 (A1-An) carried by a plurality of subjects of security and a plurality of portable devices 400 (B1-Bn) carried by a plurality of bodyguards. Setting wireless pairing between the plurality of portable devices and the plurality of calling kits and setting up the wireless pairing between the plurality of portable devices (S110), and each of the portable devices 400 (B1-Bn) is provided with a plurality of calling kits 200 ( Receiving a radio signal from (A1-An), and extracting the distance information according to the outgoing kit information and the received signal strength of each of the received radio signal (S120), and the wireless device for each portable device between a plurality of portable devices Step (S130) of sharing the signal reception origination kit information and the corresponding distance information, and generating a notification object and a message based on the set notification sound generation condition by analyzing the transmission kit information and the distance information shared by each mobile device ( S140), the notification stand Characterized in that the ring tone, and notification to the steps (S150) to output a message notifying a security distance from the mobile device.

As shown in FIGS. 5 and 6, a plurality of portable devices B1-Bn are capable of one-to-many communication with a plurality of originating kits A1-An and wireless communication pairing to enable communication between the plurality of portable devices. Set up a rocker network.

Then, each mobile device extracts the distance information for each outgoing kit by the radio signal reception strength received from the plurality of outgoing kits, and shares the extracted distance information for each outgoing kit between the portable devices. Analyzes the distance information for each shared outgoing kit and outputs a notification sound or a notification message from the corresponding portable device, and in the case of the outgoing kit equipped with a vibration module, transmits an alarm signal to the corresponding outgoing kit to be notified by vibration.

The notification sound generating condition,

Set the closest distance information among the distance information for each outgoing kit detected by each mobile device as the reference distance information of the corresponding outgoing kit, and if the reference distance information deviates from the preset notification or alarm distance, It is characterized by outputting a notification or alarm sound to the outgoing kit.

In addition, the notification sound generating condition,

If any portable device does not receive a radio signal and there is a calling kit from which distance information has not been extracted, a voice message indicating that the distance of the calling kit has not been detected may be generated and output from the portable device.

In addition, the notification sound generating condition,

When the reference distance information for each calling kit exists within a predetermined allowable distance range, the mobile device outputs a notification sound indicating that the vehicle is a normal guard distance.

In this way, when one of the calling kits is determined to be the closest distance measured by the distance from all the portable devices corresponding to the alarm, that is, if it is out of the guard group area can be notified immediately.

On the other hand, when each mobile device transmits and receives a radio signal with a plurality of outgoing kits or performs wireless communication between the plurality of mobile devices, there may be signal interference. As a method of avoiding signal interference, as in a conventional multi-hop communication method, communication is performed while changing channels automatically, or a sequential communication is performed in a time-division manner, or communication is performed by dividing into different frequency bands. can do.

7 (a) and 7 (b) are explanatory diagrams for explaining a security distance notification method according to a third embodiment of the present invention.

As shown in FIG. 7A, B1 sequentially requests radio signals to A, A2, and A3, and in response to the request signal, A1, A2, and A3 transmit a distance measurement radio signal together with the identification signal. The portable device B1 measures distance information for each calling kit, and transmits the distance information for each calling kit and handoff information to another portable device B2. B2 receives the handoff information and distance information for each calling kit from B1 and stores distance information for each calling kit.B2 also requests B1 to A1, A2 and A3 based on the handoff information, and the distance according to radio signal reception. The information is extracted and the distance information and handoff information for each originating kit in the extracted B2 are transmitted to B1.

As described above, step S140 of generating a notification sound generation target and a notification sound or a message by sharing distance information for each calling kit between the mobile devices is performed.

 B1 and B2 compare and analyze distance information for each outgoing kit and self-measured outgoing kit distance information received from B2 and B1, respectively, to generate a notification sound generation target and a notification sound or a message that is far from B1 and B2.

As shown in FIG. 7A, B1 receives a radio signal of A1, A2 and A3 to measure a distance, and passes this information to B2. Then, B2 receives a radio signal of A2 and A3 to measure a distance to B1. Pass it to share with each other. Analysis of this shared information reveals that A1, A2, and A3 are all within alarm distance from B1 or B2. In this case, a notification sound indicating the presence of the alarm within a distance may be output or may be silent. It is more preferable to notify the normal state by outputting a low level notification sound (buzzer sound) in the unit of several seconds to several tens of seconds rather than the silent.

If one of the subjects moves in the state as shown in FIG. 7A and A3 moves as shown in FIG. 7B, if B2 does not follow, A2 is set to an alarm radius (eg, 5M) in B2. The distance measurement is found out from the distance measurement, B1 is a distance from A3 is not receiving a radio signal, so B2 can generate a notification sound to inform that the subject is out of the guard zone.

B2's bodyguards can visually identify A3 and move near A3 or guide A3 near A1 and A2. Here, as shown in (b) of FIG. 7, when A3 does not move in the opposite direction to B1, but moves away from B2 and close to B1, B1 and B2 move to near B1 through information sharing. The alarm will not sound because it is known.

Therefore, even when a plurality of bodyguards are insufficient in comparison with a plurality of bodyguards, whether the bodyguards are all within the normal bodyguard range is also known, and the distance to the bodyguards is measured in real time, so that any one of the bodyguards Immediately outside the guard zone, the nearby guard's handheld device will generate an alarm alert so that action can be taken.

8 is a flow chart of a warning distance notification method of the many-to-many security system according to the fourth embodiment of the present invention, Figure 9 (a) and (b) is a security of the many-to-many security system according to another embodiment of the present invention It is explanatory drawing of distance notification method.

In the fourth embodiment of the present invention, as in the third embodiment, a plurality of portable devices and a plurality of originating kits form a local network so that the distance measurement and the security distance notification method are configured to share and analyze information between the portable devices. It is a method for notifying when the portable device and the calling kit are separated from the group by the distance between the portable devices or when the portable device is released from the guard group area.

As shown in FIG. 8,

Setting wireless pairing between a plurality of portable devices and a plurality of calling kits and wireless pairing between the plurality of portable devices (S210);

Receiving a radio signal from a plurality of outgoing kits each mobile device, extracting the outgoing kit information and the distance information according to the received signal strength of each of the received radio signal (S220),

Extracting a distance between portable devices by exchanging wireless signals between a plurality of portable devices, and sharing the distance information between each portable device, the wireless signal reception kit information for each mobile device, and the distance information with the corresponding transmission kit ( S230),

Each mobile device analyzes the distance, calling kit information and distance information between the shared mobile devices, and when any one of the mobile devices is separated by more than the set distance, the wireless communication distance of the calling kits of the portable devices is farther than the set distance. Generating a notification sound or a notification message notifying the case (S240);

 And outputting a notification sound or a notification message in the corresponding portable device (S250).

9 is an explanatory diagram for explaining a security distance notification method according to a fourth embodiment of the present invention. The case where the number of bodyguards is larger than the bodyguards will be described as an example.

A many-to-many wireless communication pairing is set between the portable devices of the plurality of bodyguards B1-B5 and the calling party of the plurality of bodyguards A1-A3, and the many-to-many wireless communication pairing is also set up between the plurality of portable devices of the bodyguards. It is desirable to set the software in such a way that the mobile devices can communicate with each other in a multi-hop manner such as Wi-Fi D2D communication. That is, each portable device can be implemented to perform a virtual access point function by software to form a network by multi-hop communication.

Thus, in order to configure a communication network between mobile devices, such as a conventional smart phone can be implemented by installing a security distance notification security app on a smartphone capable of short-range wireless communication, the calling kit is a communication module capable of short-range wireless communication with such a mobile device It can be implemented in a device having a.

Assuming that B1-B5 protects A1, A2, and A3 as shown in FIG. 9A, B4 detects only one outgoing kit A3, and the other portable devices B1-B4 each have two outgoing kits. Will be detected. At this time, if the distance between the B4 and B5 and B3 is within the set security range of the mobile device, since the normal state, B1-B5 can all output the notification sound of the normal state.

Since the movement of the subject and the body of the body is generated, as shown in (b) of FIG. 9, B5 moves out of the area that does not detect the outgoing kit, and B4 moves together with A3, where the body is far from other body. A notification sound or voice message indicating that the person is away from the subject is output, and in B4, a notification sound or voice message indicating that A3 has fallen alone in another subject group is output. Accordingly, B5 and B4 may move to other guard subjects within the guard group area according to the site situation.

As a result, in another embodiment of the present invention, in the many-to-many system, the bodyguard can easily recognize that the body is far away from the body, and even if the bodyguard is far away from the body of the body, a notification sound informs it of the body and the normal state. Therefore, even in many-to-many escort, it is possible to grasp the escalation distance in real time without a voice call and take action according to the on-site situation.

On the other hand, the present invention, by configuring the outgoing kit with a smart band, the portable device can be configured by installing a distance notification guard app on the smartphone can be applied to applications such as anti-lost devices.

13 is a control flowchart of the security distance notification device using a smart band according to the present invention.

In step S310, wireless pairing is set between the mobile device and the smart band, and D2D communication is set between the mobile devices.

The portable device receives the wireless signals of the smart bands to measure the distance for each smart band and selectively outputs a notification sound corresponding to the distance (S320).

One portable device receives wireless signals from a plurality of smart bands, measures the distance for each smart band, and selectively outputs a notification sound for each. Since this is to measure the distance to each of a plurality of specific smart band, in turn may output a notification sound corresponding to the distance, or may output a notification sound only when the predetermined distance or more.

Subsequently, when the distance measurement for each smart band is completed, the distance information for each smart band is shared between the mobile devices. This may be performed by handheld devices in order to exchange handoffs in a sequential manner, or may share information through mutual D2D communication after simultaneous progress.

Thereafter, each of the shared smart band distance information is analyzed to extract a notification object, and the notification information is generated and transmitted to the corresponding smart band (S340). It extracts whether there is a smart band outside the guard zone, only one smart band is separated, and so on.

When the smart band corresponding to the notification condition is detected, the mobile device and the smart band receiving the corresponding information output an alarm sound or a notification message, respectively, in operation S350.

As described above, in the security distance notification method using the smart band, as shown in (a) and (b) of FIG. 7, when the bodyguards (guardians) B1 and B2 are smaller than the bodyguards A1, A2, and A3. It can be used suitably. For example, dozens of children can be suitably applied when a lifelong teacher guides them to perform movements or field trips. Normally, grouped by 10 persons, each instructor teacher leads, and when a child outside of a certain area occurs, a notification sound can be generated immediately.

For example, as shown in (a) of FIG. 7, B1 and B2 exchange wireless signals with respect to each of the smart bands A1, A2, and A3, measure distances, and share and analyze the distances. B) If it is determined that A3 is out of the set distance, it outputs a notification sound to inform B2 that A3 is out, and also sends alarm information to A3 smart band to control alarm notification sound and message or flashing in A3 smart band. Can be informed.

When using the smart band, not only one-to-one escort, but also children's co-learning or plural users moving away from each other in group movements or group activities moving together in a certain area occurs in real time on the mobile device and the corresponding smart band. Inform it. In addition, it is possible to output a message or control lighting flickering by using the display module of the smart band itself even when traveling in a group package.

In addition, in the application of the present invention, a conventional smart phone is equipped with a location information measuring means (GPS module) can know its own location, but in the case of a smart band or a transmission kit, if the GPS module is equipped with a higher cost It is common not to mount the GPS module. Even if there is no location information measuring means in the outgoing kit or smart band, if the mobile device transmits and receives wireless signals to measure distance information and is separated by a long distance which is not visible, the plurality of mobile devices are applicable. Since the distance measurement information with the calling kit or smart band is different, analyzing this information can find the direction. This is a real-time notification of when a person is leaving in a crowded place or a lot of blockages, and you can find a rough direction on your handheld device so that you can move in that direction and find it immediately. You can do it.
