Among the components of the video phone system, a communication terminal capable of receiving a lobby phone call includes a video telephone, a wireless terminal, and a general wired telephone.

205 Public Switched Telephone Network (PSTN)

A telephone network that uses a telephone line that includes a public telephone network (PSTN) and an ISDN as a telephone network that can provide a calling party number with a unique telephone number.

409 IP Telephone Network

A system that can relay a telephone number in the middle of a telephone network that communicates using the Internet's IP and has recently received a telephone number and entered a complete telephone network. Including telephone network.

The present invention can be installed without an additional control device by building a video phone system installed in the entrance door of the apartment house using an IP phone network without connecting to the intercom system, yet can be conveniently constructed, with additional services remotely It relates to a video phone system that can open the door.

In general, the videophone system installed at the entrance of a large apartment house is converted to the interphone system constructed at the time of construction. In order to build all the facilities or install a line directly to one lobby phone for each generation, it is expensive to install and many videophone system cannot be installed, and existing interphone system is installed Even if it is digital or if the wire of the line is not 4, there is a problem that some functions cannot be used to construct a complete system.

In the example of using the existing video phone system, the visitor who arrives at the door of the apartment house first enters the lake of the household to be visited by using the keyboard of the lobby phone, and then presses the call button. It generates and sends data to the lake of the household, and the videophone of the generation receives a call to inform the connection. When the tenant picks up the handset of the videophone or selects a call, the image of the visitor at the door can be checked. In addition, the call can be made so that the user can open the door or stop the call after confirming the purpose of the visit.

In addition, if the lobby phone is equipped with a function to control the door by using an RF card or a password method, a resident may contact the registered RF card with a lead device, enter a password, or both to mount the lobby phone. If there is matching information by checking the registered information in the control device, the door is opened through the door part, so that the registered resident can enter and exit without talking to the resident inside.

Details of the conventional method will be described with reference to the accompanying drawings in the following.

Figure 1 is a block diagram of a conventional multi-unit video phone system, as shown in the lobby phone 104 is installed in the lobby and the video phone 106 installed for each household, the connection is a video phone control Connected around the device 105, the lobby phone 104 is a keyboard 112 for inputting the lake or telephone information of the house, speaker phone 110 for making a call with the video phone in the house, visitor image information It consists of a camera 109 for confirming, the RF card reader 111 for using an RF card, the video phone controller 105 selects the line corresponding to the lake input from the lobby phone 104 To connect the call line.

In addition, looking at the patent application related to the present patent, patent application 1019990025617 establishes the lobby phone system as a general telephone network, the visitors of the generation to visit through the keypad 112 attached to the lobby phone 104 when the visitor arrives at the entrance door If you enter the lake, you can make a phone call using a phone number registered in advance.If the resident receives a call and confirms the visitor, and then presses a certain key (# or *) on the phone, it is recognized by the lobby phone 104. Opening and closing the door.

Table 2 is a schematic diagram reconstructing the outline of the above-listed patents in the form of the present patent, which is composed of a telephone system 204, a general telephone network 205, and telephones 207 installed by generations. If you make a call to the household you want to visit through the public telephone network (PSTN) or the Integrated Information Communication Network (ISDN), the resident can open the door by pressing a specific key. It is configured to allow only the direction from the door to the generation, and it is impossible to make a reverse call because there is a problem such as a wrong call by a third party, and because of the characteristics of general telephone and ISDN, the communication speed is low. The transmission is almost impossible and cannot be provided (there is no device in the block diagram in Fig. 3). In the case of a visitor calling at the door, telephone charges are continuously generated, which is a very disadvantageous factor in that no additional communication charges are incurred when using a videophone system using an existing interphone system.

ISDN is an abbreviation of Integrated Services Digital Network and is defined as a network that aggregates and provides various communication processing services such as telephone, data, facsimile, and various communication processing services that provide communication information through one communication network. It was created with the aim of facilitating advanced service provision by integrating separate communication networks and adding various functions for each existing service. The objectives are the economicalization of communication network by digitalization, reduction of transmission error, improvement of communication quality and To provide convenience to the user by providing a variety of services, which is a kind of a general telephone network that is completely different from the IP telephone network of the present patent.

Application 3 is a block diagram of the above-described patented telephone system (lobby phone), which is connected to a control / data bus 300 and the control / data bus 300 and is a generation telephone in a multi-family house through a telephone network circuit 310. Telephone circuit controller 320 connected to the field 301, the microphone 330 and speaker 335 connected to the telephone circuit controller 320 through the telephone network circuit 310, and the control / data bus. Serial input and output device connected to the 300 and the peripheral control device 340 for controlling the door and peripherals, connected to the control / data bus 300 and connected to an external device through a serial interface (RS-232C) (Serial Input) and Output) 350, the processor 360 is connected to the control / data bus 300 to control the overall operation, the program is connected to the control / data bus 300 for the operation of the processor 360 Program memory to store A device 370, a data storage device 375 connected to the control / data bus 300 to store data for the operation of the processor 360, and a notice and an alarm connected to the control / data bus 300. A display device 380 for outputting a door, a keypad 385 connected to the control / data bus 300 to receive a key from a user, and a relay connected to the control / data bus 300 to control a plurality of relays It is configured to include a control group 390 and the voice guidance device 395 connected to the control / data bus 300 to output a guide and an alarm, but can be received when a resident makes a call from inside or outside Since there is no device, remote control of the door using caller display is impossible, and there is no device for transmitting image information, so that the visitor's image information cannot be confirmed.

An object of the present invention is to solve the above problems and to build a video phone system simply and conveniently, by building a video phone system using a lobby phone and IP phone network dedicated to IP phones, video through the existing interphone Compared to the phone system, there is no need for a separate video phone control unit to connect the lobby phone with the video phone in the house, and also the IP phone and the general phone on the sofa in the living room, not the entrance of the house where the video phone is normally installed. By using it, you can sit and take necessary actions without having to go to the entrance to open the door, and it is more convenient by using a phone that can change the ring tone by the designated phone number to distinguish the call from the lobby phone from other calls. It is possible to use it, but it is not limited to the lobby phone exclusively for IP telephones It presents a model integrated with regular phone, that in case a problem with the IP telephone network occurs, IP telephone system still will be integrated additional presented in order to complement the role because it was not verified by historians stabilize shorter than the regular telephone network.

Compared with the previous patent application, it is difficult to provide image information due to the data transmission speed when using a general telephone network, but there is no problem when using an IP telephone network. It can be confirmed by MMS or VMS, and the general telephone network has a problem of distribution of expenses by occupants due to continuous telephone charges, but it does not incur additional charges by constructing the internal network of IP telephones instead of the existing interphone videophone system. If you do not have the same unit, but the entire internal network of the apartment can be used as a video phone at no additional cost, similar to the interphone, and you need to enter or delete each individual door unit when registering a resident of a general telephone network, but use an IP telephone network. Registered residents at the server in bulk It is possible to save and manage the entire apartment from the server without any computer system related to access control, and in the patent application, it is necessary to call the lobby phone to prevent the third party from inadvertently calling. However, the caller ID is used to answer the call only if the caller is a registered person. If not, the call is automatically disconnected from the caller. You can open the door on your phone without having a key.

In other words, by using the general telephone network and the IP telephone network as a side function, the door can be opened by using the caller ID. Therefore, the residents can use the phone registered to the lobby phone without the need for a separate key. If you enter a password according to ARS after dialing the phone number of, you can open the door automatically by extracting the calling party number from the lobby phone and comparing the registered phone number with the password. Except where access control must be strictly enforced, most apartments use only the calling party number without entering a separate password. You can open the door easily by pressing SEND and then call). If there is a visitor in the absence of a person, after receiving and confirming the visitor's image information and telephone number, a resident outside can call as above and remotely open the door at the visitor's request.

Compared to the door control system, which is part of the recently activated home network, the videophone system of this patent uses a general telephone network and an IP telephone network that are already configured, rather than using a router or gateway built in an individual household. In other words, complex devices are not required separately, and registered residents can access the door by simply making a phone call, rather than accessing it from the inside or outside using a wireless Internet network, which is different from being part of a home network. .

In addition to the use of public telephone networks, RF cards, passwords, and the use of both, which are rapidly spreading recently, will be added, so that children or the elderly who do not have a mobile phone or avoid complicated things can easily use them.

In order to achieve the above object, IP-only or IP-ordinary telephones, which are installed at doors of apartments, are connected to the public telephones or IP telephone networks, and the caller display function of the telephone network is utilized. By opening the door by adding an additional RF card access control system, by issuing a card to residents who do not have a mobile phone or feel uncomfortable to use, all residents can use it conveniently. It is possible to construct an internal network by building an individual server for each apartment or by constructing a virtual internal network by tying up a certain number of telephone numbers in case of a small number of households. To keep a record of the operation of all doors in a batch for later retrieval. By doing so, it is possible to realize economic cost, ease of use, and complete security system at once.
