Description

Smart Phaser {SMART PAGER}

To a pager capable of low power wireless paging of the present invention.

A pager with a paging function called 'pager' is hidden in history with the emergence of mobile communication terminals such as mobile phones and smart phones that can communicate wirelessly with the other party.

However, mobile communication terminals, especially smart phones, are mainly used, resulting in various problems.

For example, there is a demand for a terminal that has a simple calling function different from a smart phone, can be downsized, and has a low price. However, since there is no communication service provider supporting the communication bandwidth of the existing pager along with the appearance of the mobile communication terminal, there is a problem that it is difficult to provide the pager satisfying the user's request.

Korean Patent Laid-Open Publication No. 1997-0008963 discloses a wireless pager having a display control function for a received message. However, the conventional wireless pager uses a communication bandwidth of a conventional pager, and thus is currently unavailable.

Korean Patent Publication No. 1997-0008963

The present invention is to provide a pager using LPWA.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not intended to limit the invention to the precise forms disclosed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The sizes and shapes of the components shown in the drawings may be exaggerated for clarity and convenience. In addition, terms defined in consideration of the configuration and operation of the present invention may be changed according to the intention or custom of the user, the operator. Definitions of these terms should be based on the content of this specification.

1 is a schematic view showing a phaser of the present invention.

The pager shown in FIG. 1 may include a first communication unit 110, a display unit 180, an input unit 150, and a case 190.

The first communication unit 110 can communicate with other terminals 10 using an LPWA (Low Power Wide Area Network). In order to use the LPWA, the first communication unit 110 may include a communication module supporting LPWA.

LPWA is an IoT proprietary network technology featuring a wide range of communication coverage, low bandwidth, long battery life and low power consumption. The LPWA protocol focuses on the exchange of information between objects and differs from the protocol such as the LTE network.

LTE network, CDMA network, etc., but a high capacity battery is required because high power is required. There is a problem that the miniaturization is limited due to the high capacity battery and the charge is high. Therefore, at present, a pager using an LTE network or the like is not practicable at a time when a smart phone using an LTE network or the like is provided.

On the other hand, the LPWA for the Internet, which requires a small amount of data to be transmitted and received, is insufficient in terms of communication speed compared with the LTE network, and has many merits in terms of power consumption, communication distance, and usage fees.

The first communication unit 110 includes a communication module using LPWA, and can transmit and receive character data and the like that can be recognized by the user, instead of data transmitted and received between objects.

LPWA may include at least one of LoRa (Long Range), SIGFOX, Long Term Evolution Machine Type Communication (LTE-M), NarrowBand-Internet of Things (NB-IoT)

LoRa has a frequency of the license-exempt band (900MHz), and transmission speed varies from 300bps to 5kbps. LTE networks, and 170 companies including IBM and SK Telecom are continuing their research with the Laura Alliance.

SIGFOX has a frequency of the license-exempt band (900MHz) and has a transmission rate of 100bps. This technology is the IoT standard technology that European Telecommunication Standards Association (ISP) has developed with the French sig technology. It is used for low power long distance. Also, a separate network is used instead of the existing communication network.

LTE-M transmits data at a transmission rate of 220kbps to the existing LTE frequency. It is mainly used for low-power long distance method and it has the advantage of using existing LTE network. Since the LTE-M has a relatively fast transmission / reception speed, it is also possible to transmit and receive a picture or a low-capacity moving picture compared with LoRa, which is suitable for transmission and reception of character data. On the other hand, since the existing LTE network is used, there is a disadvantage that the power consumption is rather large and the use cost is high.

NB-IoT uses the LTE frequency corresponding to the licensed band and transmits data at a transmission rate of 100 kbps. It is the IoT scheme that KT is currently pursuing in parallel with LTE-M.

The first communication unit 110 using the LPWA focuses on exchanging data that can be recognized by the user, rather than exchanging data between objects. Accordingly, the pager of the present invention may be provided with a display unit 180 for displaying a received message received through the first communication unit 110. [ The received message at this time may include a paging signal for operating an alarm unit (not shown) included in the pager.

The display unit 180 may include a display such as an LCD or an OLED. The received message displayed through the display unit 180 may include characters such as English and Korean that can be recognized by the user.

Since the pager of the present invention corresponds to the portable terminal 10, the case 190 in which the first communication unit 110 and the display unit 180 are incorporated can be formed to be portable and small size.

The pager of the present invention can send a message to another pager. The input 150 may be used to send a message to another phaser.

The input unit 150 is embedded in the case 190 and can generate a transmission message to be transmitted through the first communication unit 110. The input unit 150 may include a keypad, a touchpad, a keyboard, buttons, and the like. When the input unit 150 is a touch pad, the input unit 150 may be formed integrally with the display unit 180.

With the development of the mobile communication terminal 10, there is a demand for an old pager at a present time when a complicated function smart phone is to be used forcibly. In particular, there is a growing demand for phasers in households, companies, hospitals, and organizations where there is no need for smartphones such as children or adolescents. At present, using high-power, high-cost communication network such as LTE network, existing pager is difficult to communicate really, and it is difficult to use and join. The pager of the present invention can send and receive short messages using the LPWA which is in the commercialization stage. In addition, the pager of the present invention can be used as a multipurpose text pager capable of maintaining realistic communication while maintaining the calling function.

In the pager of the present invention, a battery may be installed inside the case 190. Since the first communication unit 110 consumes low power, the capacity of the battery can be reduced. It is sufficient to install only the coin-sized first communication unit 110 and the small-capacity small-sized battery in the case 190, so that it is possible to sufficiently reduce the size. In addition, the extra battery power can be used for other purposes.

For example, the pager of the present invention can be used as a stethoscope using the power of a battery.

2 is a schematic view showing a partial cross-section of the phaser of the present invention.

The pager of the present invention may include an interface unit and a microphone 130.

The interface part is formed in the case 190 and can acquire the bio-acoustics of the body. When the display unit 180 is disposed on one side of the case 190, the interface unit can be disposed on the other side of the case 190. [

The interface section may be provided with a diaphragm 111 having one side facing the body 50 and a sound pickup 113 provided on the other side of the diaphragm 111. [ At this time, the sound collector 113 may be formed in a funnel shape for collecting the body sound of the body.

The case 190 may be provided with a communication hole 119 for connecting the inside and the outside. The communication hole 119 may be formed in the shape of a closed circle such as a circle on a plane, and the communication hole 119 may be formed in the center of the sound collector 113. The bio-acoustics collected at the sound collector 113 may be output through the communication hole 119 formed at the center of the sound collector 113.

The microphone 130 is formed in the case 190 and can convert the bio-acoustic signal into a first signal that can be processed by the terminal 10. It is difficult for the bio-acoustic such as the heartbeat sound of the body 50 to directly acquire the bio-sound from the microphone 130 even if the microphone 130 directly contacts the body 50 with a very fine sound. The interface unit can acquire the bioacoustic of the human or animal body 50 to a level required by the microphone 130.

The microphone 130 may be installed to face the communication hole 119 on the opposite surface of the case 190 facing the body. Since the microphone 130 is installed facing the communication hole 119, the sound picked up by the sound collector 113 can be reliably input to the microphone 130 via the communication hole 119.

The microphone 130 exposed on the other surface of the case 190 may be sealed by the sealing material 114 to prevent noise from being input to the microphone 130 from the other side of the case 190. [

Meanwhile, the phaser of the present invention may include the tightening portion 170 to exclude the noise such as the fricative sound sweeping the diaphragm 111 to the body 50 or the garment.

The tight fitting portion 170 may be formed integrally with the case 190 or may be formed separately.

The contact portion 170 is an element which is brought into close contact with the body 50 and can be interposed between the body 50 and the diaphragm 111 which is provided to face the body 50. The diaphragm 111 can be disposed at a position spaced from the body 50 by the tight contact portion 170 interposed therebetween.

The diaphragm 111 disposed at a position spaced apart from the body 50 can be excluded from contact with the body 50 or a garment clad with the body 50. [ As a result, the noise caused by the contact of the body 50 or the clothes with the diaphragm 111 by the tight contact portion 170 can be originally excluded. Therefore, it is not necessary to provide an additional means such as a filter for removing the noise in the case 190, which is suitable for the pager of the present invention which pursues low power.

The contact portion 170 may be formed in a ring shape of the hollow 179 surrounding the diaphragm 111 in a plane. The adhered portion 170 may be formed in a funnel shape in which the diameter of the hollow 179 decreases from the body 50 toward the diaphragm 111. [ According to the funnel-shaped tightly fitting portion 170, there is an effect that the living body of the body 50 is partially collected by the tightly fitting portion 170.

Meanwhile, the pager of the present invention may include a speaker 140 that converts a second signal received from the terminal 10 (30) into a sound wave that can be heard by a person. At this time, the interface unit may be configured to transmit sound waves output from the speaker 140 to the body 50.

A battery (not shown) that provides driving power to the first communication unit 110 may also provide driving power to the microphone 130 and the speaker 140.

The speaker 140 may be installed at a position facing the diaphragm 111 in the sound pickup unit 113.

The sound wave output from the speaker 140 can be output to the acoustic space 117 between the diaphragm 111 and the sound collector 113. [ A communication hole 119 may be formed in the sound collector 113 at a position facing the microphone 130. An auxiliary hole 118 may be formed on the side of the communication hole 119. The auxiliary hole 118 may be formed at a position where the speaker 140 faces and the sound wave output from the speaker 140 may be output to the acoustic space 117 through the auxiliary hole 118.

The diaphragm 111 can transmit the bio-acoustic sound to the microphone 130 when the microphone 130 is driven. The diaphragm 111 can be vibrated by the sound waves output to the acoustic space 117 when the speaker 140 is driven. The vibration of the diaphragm 111 by the sound wave can be transmitted to the body 50 and the fetus located in the body 50 can be heard.

For example, a user can acquire a heartbeat sound of a fetus using the microphone 130 provided in the phaser of the present invention, and can listen to the fetish music or the voice of the mother by using the speaker 140 provided in the phaser . The preaching music or the voice of the mother may be the second signal received from the terminal 10.

The phaser of the present invention may be in a state in which acoustic output means for outputting bio-acoustic signals received through the microphone 130 is omitted to realize low power. Therefore, the bio-acoustic needs to be transmitted to another terminal 10 equipped with the sound output means. In addition, the pager of the present invention can receive the second signal from the corresponding terminal 10. At this time, it may be inappropriate to use the LPWA for communication with the other terminal 10. This is because LPWA provides a slow communication speed in which real-time transmission of acoustic data is difficult.

A second communication unit (not shown) may be provided in the pager of the present invention for transmission of the biomedical sound and reception of the second signal.

The second communication unit is installed in the case 190 and can communicate with the terminal 10 using a short-range wireless communication network such as Bluetooth. And the second communication unit may transmit the first signal output from the microphone 130 to the terminal 10. [

Meanwhile, the pager of the present invention may include a storage unit (not shown) for storing data transmitted and received through the first communication unit 110. According to the storage unit, the first signal output from the microphone 130 may be stored in the storage unit, and then transmitted to the terminal 10 in accordance with the LPWA speed through the first communication unit 110.

Since the pager of the present invention can be manufactured in a small size, various additional functions other than the stethoscope can be added to the pager.

For example, the case 190 may include at least one of a near field communication (NFC) module for payment, an entry / exit approval module for the setting gate, and a GPS (Global Positioning System) module for grasping the current position of the case 190 . In the case of the payment NFC module and the I / O approval module, there may be a situation where authentication data must be received from the management server. At this time, the authentication data can be sufficiently received through the first communication unit. The authentication data can be used to verify the integrity of the payment NFC module or the I / O approval module.

1, the display unit 180 may be provided with a first messenger 210 for exchanging messages with the other party's terminal 10 using the first communication unit 110. [ At this time, the first messenger 210 can not communicate with the second messenger 220 using the LTE network due to differences in protocols and the like.

It is preferable that means for communicating with the second messenger 220 using the LPWA and another communication network is provided.

The first server 310 for managing the first messenger 210 includes a conversion unit 311 for converting the first message of the first messenger 210 and the second message of the second messenger 220 . At this time, the second messenger 220 may be a messenger such as a Kakao Talk using another communication network different from LPWA.

The first messenger 210 by the conversion unit 311 transmits the message including the terminal 10 on which the messenger using the LPWA is installed and the terminal 10 on which the second messenger 220 using the other communication network distinguished from the LPWA are mounted, You can send and receive.

The second server 320 may provide the second message to the terminal 10 such as a smart phone and the second message may be normally displayed on the terminal 10.

The first server 310 may convert the second message into a first message and transmit the second message to the first communication unit 110 when the second message is received from the second server 320. Accordingly, the message input to the KakaoTalk installed on the smartphone is displayed on the first messenger 210 named 'Aladdin' via the second server 320 and the conversion unit 311 of the first server 310 .

 The pager of the present invention described above can have a bi-directional text calling function by the first communication unit 110. It is possible to send and receive bidirectional characters such as kakao talk, line and so on. With LTE-M, it is possible to send and receive simple pictures and videos.
