Visitor Identification using Mobile Station and Door Lock Control at Real Time using DTMF Signal In Conversation}

The present invention relates to a MOBELL system, and when the visitor presses the call button, in the absence of the owner calls the host to the outside through the MOBELL system to check the visitor through a direct call (voice and video) and, if necessary, the door in real time during the call It relates to a method that can control.

Conventional visitor identification method is a method of notifying the user's mobile communication terminal in a text message by using an intercom or home server, a method of capturing the image of the visitor's face to be sent to the mobile terminal for display, search and confirm the data stored in the DB How to do it. However, these prior arts are difficult to check the visitor's condition, and the connection time is long because the multiple steps are required to confirm the visitor, and the connection rate is inconvenient.

In the conventional door lock control system, 'application number 10-2003-0009166, the invention name; door locking control device using a telephone' can conveniently lock and unlock the door lock using a telephone at a remote location.

However, the above door lock control method does not allow the user to confirm the exact identity and business of the visitor, and can only open the door in peace to the visitor because only the door lock can be controlled.

As a conventional technique for solving this problem, 'Application No. 10-2002-0021097, the name of the invention; Door phone system that can communicate with the external mobile communication terminal is through the wired / wireless integrated home gateway to check the identity of the visitor from a remote place through voice and video call with the external mobile communication terminal when the user is not in the house and lock the door if necessary. To be released.

However, the well-known 10-2002-0021097 technology also allows the user to check the visitor's business through a direct call with the visitor when the user is absent, but cannot control the door lock in real time during the call, and also cannot check whether the door lock is controlled in real time. In order to control the door of the home from a remote location, the user has to try again through the home gateway.

Therefore, in order to solve the above problems, the present invention interworks with a mobile communication network by mounting a CDMA matching module for mobile communication, and also works with a public switched telephone network (PSTN) by mounting a PSTN matching module. (MOBELL) system that can check visitor's business anytime, anywhere through the call with the visitor, and how to control the door lock in real time through DTMF signal injection during the call between the visitor and the user. Its purpose is to provide a convenient service that transcends time and space between users and visitors.

In order to achieve the above object, the present invention provides a call control method after a visitor presses a call button in a MOBELL system, comprising: capturing a visitor image and checking a user's absence; An automatic origination and user response step according to priority; Checking the visitor and controlling the door lock during a call; A visitor business recording step when the visitor fails to connect with the user; MOBELL system characterized by consisting of the call history and the captured image of the visitor.

In addition, the design proposed through the present invention is a sample model of the triangular relationship of the requester (visitor), the user (homeowner), and the behavior (door lock control), so that it can be dedicated to various applications. For example, when a dog (requestor) who is alone at home barks (detected by a sensor), the dog owner (user) contacts the mobile terminal to monitor the dog's situation, and then feeds the food through a feeder control (act) using DTMF signals. Service that provides immediate delivery, when the patient's (requester's) pulse or blood pressure is abnormal (detected by the sensor), by contacting the patient's guardian or doctor to monitor the situation through a call with the patient and then to connect to the corresponding action It has features that can be applied to various fields such as.

The configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

Referring to Figure 1, MOBELL service network is divided into home network, external network, user telephone. The home network includes a MOBELL (100) system for connecting a call between the visitor and an external user by interworking with an external network when the user is away from the home when the visitor presses a call button; A home server 200 for storing a call record (eg, a visitor's call time, a video, and whether the door lock is opened or closed) between the visitor and the external user; The door lock 300 is configured to control the door. The external network includes a mobile communication network 400 interworking when a user's phone registered and attempted to receive a call is a mobile phone, and a public telephone network 500 interworking when a wired telephone is connected. The user phone is divided into a mobile communication terminal 600 or a wired telephone 700.

2 illustrates a configuration of the MOBELL 100 system, and includes a touch pad LCD module 111 for use in initial information input and setting; A camera 112 for photographing the visitor; A video codec 113 for recording an image; An audio codec 114 for processing voice; A speaker 115, a microphone 116, and an amplifier 117 for a visitor to have a voice conversation with an external user; A CDMA module 118 and a PSTN module 119 for interworking with a mobile communication network and a public telephone network; A DTMF decoder 120 for analyzing a DTMF signal corresponding to an access number and a password inputted from a user's mobile communication terminal 600; A controller 121 for controlling the door lock 300 according to the DTMF decoder analysis result; A LAN module 125 for connecting with the home server 200 to store call records; An auxiliary power source 122 for providing backup power in case of emergency and power failure in a home; It is composed of a sensor 123 and a sensor detector 124 for detecting a change in the external environment as an application service and connecting it to a user.

The various components of the MOBELL 100 system match each other via a bus line 130.

3 is divided into a visitor image capturing and user absence checking step (first step) and an automatic sending and user response step (second step) according to priority.

In the first step, when the MOBELL system receives the call button signal of the visitor in the idle state (S810) (S820), the image of the visitor is captured (S830). After that, it is determined whether the user is absent in the home, and when the user is busy, the normal user service is performed (S841).

In step 2, when the user is not in the home, the user automatically makes a call according to the priority (S850), sets the waiting time for the response (S860), and waits for the user's response (S870). If the user answers (S880), the call between the user and the visitor is possible (S890). If the user does not answer within a certain time in the answering standby state (S871), the user telephone of the next rank is called. This procedure continues sequentially until the last user set in advance (S872). If there is no response to the last user specified in the priority list, the MOBELL system notifies the visitor (S874), sets the recording waiting time (S875), and waits to record the visitor's image (S876).

4 shows the visitor confirmation and door lock control step (third step) during the call. During the call between the visitor and the user (S900), when the access number for controlling the door lock is received from the user (S910), the MOBELL system blocks the speaker (S920). Thereafter, the user inputs a password input guide broadcast (S930), and waits for a password to be input (S940). If a password is input (S950), the MOBELL system determines whether the password matches (S960), and if the password matches, it sends a door lock control signal (S970) to control the door lock. Then, the speaker is connected (S980) so that the call between the visitor and the user can be continued (S990). If the password does not match, the password error counter is incremented (S961), and if the password error counter does not exceed the limit set in the MOBELL system (S962), a password error announcement is sent (S963), and the user's password is reset. Wait for input (S940). However, if the number of re-entry passwords exceeds the allowable number set in the MOBELL system, a password error allowance exceeding announcement is sent (S964), and a speaker is connected (S980) so that the call between the visitor and the user can be continued ( S990).

5 illustrates a visitor recording step (fourth step) when the visitor fails to connect with the user.

If the visitor wants to leave the business in the recording standby state (S1120) (S1130), the MOBELL system requests the home server to record the visitor's business (S1140). After setting the recording request response waiting time (S1150), the device waits for a recording request response (S1160). When the home server responds to the recording request (S1170) in the recording request response waiting state (S1160), the voice and image of the visitor are recorded (S1180). When the visitor presses the OK button after recording (S1190), the home server requests to stop recording (S1200), and after storing the call history and the captured image of the visitor (S1210), it is in a dormant state (S1230). However, if the home server does not respond to the recording request within the specified time in the recording request response waiting state (S1160) (S1171), the recording error guidance to the visitor (S1170) and after storing the call history and the captured image of the visitor (S1210) ) Is in a resting state (S1230).

On the other hand, in the recording standby state (S1120), if the visitor does not want to leave the business (S1131) after storing the call history and the captured image of the visitor (S1210) goes to a dormant state (S1230).

6 shows a step (stage 5) for storing a MOBELL system call history and a captured image.

When the user who is in a call with the visitor (S1000) terminates the call (S1010), the MOBELL system is in a dormant state after storing the call history and the captured image of the visitor to the home server (S1020).

As described above, when the visitor presses the call button, the present invention automatically calls the owner's phone (mobile communication terminal or landline phone) registered in advance in the absence of the owner to directly confirm the visitor by voice and video call between the owner and the visitor. After that, the present invention relates to a method of controlling a door lock by injecting a DTMF signal into a communication path. In this way, the following excellent effects can be obtained.

First, when a visitor visits the user's house, the user can connect to a mobile communication terminal or a wired telephone device set in advance through the MOBELL system to enable voice and video calls even when the user is outside the home.

Through this, the security effect can be achieved by providing an environment like a home owner, and it can overcome the limitation of time and space between the visitor and the user.

Second, in case the outside user wants to send the visitor into the house while talking with the visitor, the user can control the door lock in real time by injecting DTMF signal on the call path through the push button and check the control situation in real time. .

Through this, a separate connection process for the door lock control can be omitted, and the time delay occurring at the time of connection can be reduced. In addition, various errors that may occur during the connection process can be avoided. Various additional services can be applied to development by integrating such technologies related to real-time control during a call to services in various fields.
