As shown in FIG. 1, the video telephone service robot 10 includes an external connection unit 100, a user location information retrieval unit 200, a moving unit unit 300, and a video call unit 400.

Here, the robot may be any type of mechanical device that provides a user with various functions of the present invention such as a video call. The user of the present invention is preferably intended for patients such as hospitals, medical centers and nursing homes.

The external connection unit 100 is a component that connects with an external wired / wireless communication network to transmit and receive voice, data, images, and the like with the outside. You can connect to your current 3G mobile network, or to your mobile WiMAX or LTE network, which will become the 4G standard in the future.

The external connection unit 100 may receive a robot call signal by a robot call means installed near the user. The robot call means may be installed in a characteristic place in a building, such as a hospital room or a resting room, and preferably a bell that can be easily operated by the user. That is, when the user presses the bell which is the robot call means in his / her room, the robot 10 receives the robot call signal through the external connection unit 100.

The user location information search unit 200 searches for a user in a building to obtain location information of the user. In the present invention, when a person outside the hospital tries to talk to the patient in the hospital, the user location information search unit 200 searches for the user in the hospital to obtain the location information of the user. Of course, it is also possible to use in the company organization of a general building or building other than a hospital, medical center, nursing home, in which case, the user may be an employee of the company, not the patient.

In addition, the user location information retrieval unit 200 stores in-building location information that stores location information acquired by installing a plurality of RFID readers in the building to read information on an object in the building and RFID tags attached to the user. The storage unit (not shown) may be included in the robot 10.

In addition, the user location information retrieval unit 200 stores in-building location information that stores location information acquired by installing a plurality of RFID readers in the building to read information on an object in the building and RFID tags attached to the user. In communication with a storage server (not shown), it is possible to retrieve the location information of the user.

In this case, the robot 10 transmits a signal for requesting location information of a specific user to the location information storage server in the building, and the location information storage server in the building receives the location information of the corresponding user, and then The location information is transmitted to the robot 10. Such transmission and reception is also possible using a private network in the building.

In the above description, the user location information retrieval unit 200 searches for a location of a user using an RFID system. However, this is not necessarily limited thereto. For example, it is also possible to search for the location of the user using ultrasonic waves. In this case, a plurality of ultrasonic sensors are installed in the building, an ultrasonic receiver is installed in the user's clothing, and the ultrasonic receiver installed in the user's clothing receives the ultrasonic wave generated from the ultrasonic generator, so that the position of the user can be grasped.

In general, when a call is received from an outsider, through the search result of the user location information search unit 200, when the user's current location is in an area where a phone call cannot be made, a voice memorandum for a phone call is not already stored. Can be. Here, the area where the phone call is impossible may mean a case where the user is located in the bathroom, in the rehabilitation center, or in consultation with the attending physician.

As a result of the search result of the user location information search unit 200, it may be known that the user is located in the area where the phone call is impossible. However, if the user comes to the phone call dead zone by storing the schedule of the user in advance and setting the time zone for the non-telephone call, Appropriate announcements are also possible.

In addition, the phone call can be guided to the outsider together with the available phone call time. Even in this case, it is possible to set a time zone during which a telephone call is possible by storing the schedule of the user in advance.

In addition, when the user is not allowed to talk on the phone, when the user's subsequent location enters a phone call available area through the search result of the user location information search unit 200, the user may be notified of the missed call. . In this case, the user location information search unit 200 needs to track location information of the user. Here, when the missed call is notified, it is possible to notify that there is a missed call by voice using a speaker.

On the other hand, the moving unit 300 is a configuration that enables the position movement of the robot 10. In general, the moving unit 300 is preferably composed of two wheels installed at the bottom of the robot 10 and a driving motor (not shown) for driving the wheels. It is also possible to include a reducer between the drive motor and the wheel. In this case, the direction of the robot 10 can be switched by changing the driving speeds of the two wheels. It is also possible to change the direction of the robot 10 in the same manner as the McCannum wheel type.

The moving unit may further include an obstacle detecting unit for detecting an obstacle. In this case, the obstacle detection unit may detect an obstacle using ultrasonic waves, and real-time obstacle detection may be performed through image processing technology.

When the robot call signal is received through the external connection unit 100, the robot 10 moves to a place where the robot call means that transmits the robot call signal is installed by the moving unit 300. That is, when the user calls the robot, the robot 10 moves to the place where the user is. In this case, the robot 10 may move to the place where the robot call means is installed by using the location information in the building stored in the location information storage unit.

The video call part 400 is a part which enables the video call of the user in a building. The video call unit 400 preferably includes a microphone, a speaker, and a display unit for enabling a video call. In addition, the display unit is preferably a touch screen display.

In addition, when a user in the building makes a call, it is possible to call a phone number corresponding to the picture by touching a previously stored picture or to make a call by touching a number on the display unit. 2 illustrates a case of making a call by touching a number on the display unit, and FIG. 3 illustrates a case of making a call to a phone number corresponding to the picture by touching a previously stored picture.

As shown in FIG. 2, when making a phone call by touching a number on the display unit, the phone number may be matched with the picture of the corresponding phone number counterpart and stored even after the phone call is completed or during a phone call. The picture of the corresponding phone number can be captured by taking a picture during a video call. In this case, the image processing unit for recognizing the other party's face may be further included.

The apparatus may further include a treatment video storage configured to share a previously stored treatment video with a video call counterpart according to a user's command or program during a video call. In this case, the user's command is generally touched by the user on the touch screen.

In the upper right of FIG. 2, a picture of the user himself is shown, and in the middle of the right side, a screen portion indicating a previously stored treatment video can be placed and shared with the video call counterpart. In this case, the treatment video may be played on the full screen of the display unit, or the treatment video may be played on some small screens. Instead of transmitting the user's image captured by the camera (not shown) mounted on the robot during the video call, the treatment video is transmitted to the other party's mobile terminal.

By doing so, it is possible to prevent the case where a user, especially an elderly person in an elderly nursing hospital, does not have a subject of conversation that can be shared with a son, grandchild, or granddaughter, and thus becomes reluctant to call. You can make a phone call while watching a treatment video with your family. Through this, you can reduce the emotional distance between families and give the elderly an emotional stability and maximize the effect of treatment. Furthermore, the family can understand the progress of treatment and the degree of improvement, thereby increasing the credibility of the hospital, thereby enhancing the image for the hospital and ensuring the justification for additional medical expenses.

In addition, in response to a user's command or program during a video call, a treatment video of a storage server external to the robot may be received and the treatment video may be shared with a video call counterpart. In this case, the robot does not store the treatment video by itself, but requests the external storage server to transmit the treatment video, and the external storage server that receives the request transmits the treatment video to the video call robot 10 and the counterpart. It is transmitted to the mobile terminal.

Although the description has been made assuming one treatment video, it is also possible that a plurality of treatment videos exist and the user can select and play the treatment video among them.

Here, sharing the treatment video with the video call counterpart according to the program means that the treatment video is automatically played simultaneously on the screen of the video call counterpart and the display unit of the robot as viewed by the elderly patient at an appropriate timing for the elderly patient. It is a function to continue the theme of.

The apparatus may further include a user basic information storage unit configured to share basic information of a user including at least one of pulse, body temperature, and oxygen saturation level with a video call counterpart according to a user's command or program during a video call. have. In this case, the user's command is generally touched by the user on the touch screen.

In addition, according to a user's command or program during a video call, the user's basic information including at least one of pulse, body temperature, or oxygen saturation is received from a storage server external to the robot, and the user's basic information is shared with the video call counterpart. can do.

In this case, the robot does not store the basic user information by itself, but requests the external storage server to transmit the basic user information, and the external storage server that receives the request transmits the basic information of the user to a video call robot ( 10) and the other party's mobile terminal.

In this case, the external storage server receives the information from the pulse sensor, body temperature sensor or oxygen saturation sensor attached to the elderly patient in order to obtain the pulse, body temperature or oxygen saturation information of the user (elderly patient) in real time, It is necessary to update the real time information. It is also possible to implement this by utilizing a sensor network configuration.

Similarly, there is no subject of conversation that can be shared with a son, grandson or granddaughter, such as an elderly person in a nursing home, especially a nursing home. You can make a phone call while looking at the basic information of the user like a family. Through this, it is possible to give emotional stability to the elderly by maximizing the emotional distance between families and further maximize the effect of treatment. Furthermore, the family can understand the progress of treatment and the degree of improvement, thereby increasing the credibility of the hospital, thereby enhancing the image for the hospital and ensuring the justification for additional medical expenses.

The user can make a phone call with the family using the robot 10, and can consult with a doctor and a nurse through a phone call. Although not shown, a separate button may be provided at one side of the display unit of FIGS. 2 and 3 for a call connection with a doctor or a doctor and a nurse. In this case, when the user presses this button, the robot 10 first checks the available state of the doctor or nurse that the user wants to consult through the external connection 100 and the private communication network in the building, and when the call is possible, Try to connect the call.

4 is a diagram illustrating an example of a case where basic information of a user is displayed on a main screen of a display unit.

In addition, it may further include a battery unit for supplying power to each component of the robot (10). In addition, when there is no task given to the robot, for example, when there is no demand for a video call and the remaining capacity of the battery falls below an appropriate level, it is preferable to move to a charging station for charging the battery unit to perform charging.

Meanwhile, the robot 10 may further include a phone number matching table for registering a phone number corresponding to the user. Of course, it is also possible to have a telephone number matching table in a database outside the robot and obtain information by communicating with a database outside of the robot.

In general, when a call comes from a phone number existing in the phone number matching table, the robot moves through the moving unit 300 so that the user can answer the call. The robot can move and reach the user, giving the user the opportunity to choose whether to accept or reject the call. It is possible to ask by voice or to display by text on the display. In addition, whether to answer or reject the call, or hear the answer from the user can also be through the voice recognition, it is possible to receive the answer by touching "telephone connection" or "call rejection" displayed on the display.

The robot 10 may further include a voice recognition unit for voice recognition.

In this case, when a call comes from a telephone number that does not exist in the telephone number matching table, it is possible to confirm the name of the user who wants to make a telephone call through the voice recognition unit.

In addition, when a call comes from a phone number that does not exist in the phone number matching table, the robot 10 moves to the place where the nearest nurse or caregiver is located according to its location, and connects the incoming call with the nurse or caregiver nearby. In addition, a nurse or caregiver who has made a call can be provided with location information in the building, for example, an internal map of a hospital, so as to select a patient to be connected to the call.

Moreover, when a telephone call comes from the telephone number which exists in the telephone number matching table corresponding to a plurality of users, it is also possible to confirm the name of the user who wants to talk among the plurality of users through the voice recognition unit.

As an example, when a call comes from an outsider named "Hong Gil-Dong", it is assumed that there are two patients who correspond to the outsider of Hong Gil-Dong as the father and mother of Hong Gil-Dong. In this case, the robot should decide whether to go to room 870, where Hong's father is, or go to room 504, where Hong's mother is. The robot can ask Hong Gil-dong whether he is looking for Hong-gil-dong's father (Hong Seo-bum) or Hong-gil-dong's mother (Jo Gap-kyung) with a mechanical sound. At this time, Hong Gil-dong recognizes that Hong Seo-bum is looking for Hong Seo-beom, and then moves to 870 where Hong Seo-bum is located.

In addition, the robot 10 may store a phone call black list. The phone call black list lists phone numbers that are expected to be unnecessary to the user, such as an advertisement phone and a recipient phone, and the call can be blocked when a call comes from a phone number on the phone call black list.

In addition, when a call comes from an outsider, the robot 10 may determine whether or not to connect a phone call according to a situation of a user who should receive an incoming call. For example, when the son calls the mother, the mother can talk on the phone, or if other patients in the room where the mother is sleeping, the robot 10 has a nurse through the vehicle unit 300 After moving to another place, the phone is brought in so that the patient can be taken out, and the son's phone can be connected to the mother.

In another situation, when the son calls the mother, assuming that the mother is sleeping, the robot 10 does not make a phone call, and the machine 10 notifies the mother that he is sleeping, or to the telephone number that called. You can send a text to let your mother know you are sleeping. At this time, the robot 10 may store the telephone number that has been dialed and then notify the user that the telephone has been called when the corresponding user, that is, the mother wakes up, and attempt to connect the telephone.

In addition, when making a call through the video call unit, the user may further include a charging unit for charging a telephone fee to the user.

The video call unit may further include a screen switching unit that enables to change the position of the screen element or the size of the screen element in response to a user's command (eg, a voice command) or a touch on the display unit. can do. For example, when the "second screen" is touched during the video call, the moving picture or the patient information screen of the "main screen" is terminated, and the call subject on the sub screen is moved to the center screen. 3 shows an example of a screen phone button.

Here, although the present invention has been described on the assumption that there is only one robot, the hospital may operate 2-3 robots for each floor.

Through the video telephony service robot as in the present invention, a function of visiting a user (elderly patient) who wants to make a call, a function of automatically finding a receiving user when a call is received from the outside, and automatically recognizes when the receiving user cannot receive a call. The ability to answer questions, identify the number of users, and provide a customized user interface to the user (patient) (for example, the ability to express words in words to a patient who can't speak) When there is no requestor or when the battery needs to be charged, it automatically goes to the charging station to charge it, finds a video suitable for the patient's conversation status, and helps to talk, and the patient's basic information (pulse, blood pressure, temperature, etc.) USN sensor communication module function suitable for elderly patients to acquire, identify the caller (user) It provides an automatic billing function for communication charges, so that the patient can be billed when the patient is discharged from the hospital, and the patient, family, and doctor can make a conference call so that the doctor can hear the opinion during the video call. It is possible.

The robot may further include not only a function for a video call but also a configuration for providing convenience to a user. For example, devices such as air cleaners and cameras may be mounted. If the air cleaner is mounted on the robot, the air cleaner may be configured to be operated by the user's operation or to be automatically operated according to the air pollution level at the place where the robot is located. In addition, if the camera is mounted on the robot, it is also possible to take a family picture of the user using the camera.

In addition, when the robot is a humanoid robot, it may be provided with a function of moving a certain body part such as a head, an arm, a leg, and shaking a gang, and greeting a new person when a building enters.
