Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present inventors two-line access control system having the above problems, solving means and effects.

1 is a block diagram of a two-line access control system according to an embodiment of the present invention.

As shown in FIG. 1, the two-wire access control system according to the present invention is connected to a household terminal 10 installed in each household and a household terminal 10 installed in each household by two lines. The connection controller 20 and the connection controller 20 are connected in two lines, and the common entrance terminal 30 performs data communication with the generation terminal 10 under the control of the connection controller 20. ) Here, it may further include a security terminal for the terminal 40 is connected to the connection controller 20 in two lines to strengthen the access control.

The generation terminal 10 may include any terminal provided in each household and capable of performing data communication with a terminal for security guard, a terminal for common entrance, or a terminal for household installed in another household. For example, a digital interphone that transmits and receives data of a voice call and a door open signal, and a digital video phone that adds a function of transmitting and receiving video, crime prevention, gas, and a fire detector to the digital interphone may be a terminal for generations. .

The generation terminal 10 is a terminal connected to a communication network of an access control system constructed with two wires, and may perform data communication with the common entrance terminal 30 by relaying the connection controller 20. Therefore, the access control of the automatic door after the call with the terminal for the common entrance can be performed by two lines with the help of the relay role of the access controller 20.

Each generation terminal 10 performs data communication with the connection controller 20, and finally data communication with the common entrance terminal 30, security terminal 40 or another generation of generation terminals. It includes a transmitting module and a receiving module to perform the operation.

The transmission module included in each generation terminal 10 includes a transmission buffer unit 11, a data moving unit 12, and a D / A converter 13, as shown in FIG. The reception module included in each generation terminal 10 includes an A / D converter 14, a data separation unit 15, and a reception buffer unit 16 as shown in FIG. 2.

The transmission buffer unit 11 of the transmission module stores data input through the input means of the generation terminal 10. The input means includes a microphone, a camera, a keypad (or a touch pad) and a detector such as a crime prevention, a gas, a fire, and the like. Therefore, the input data includes audio data, video data, key input data, and sensing signal data.

The voice data is data that a user in the home intends to transmit to the common entrance terminal 30, the guard terminal 40, or another generation generation terminal 10 through a microphone. The image data is data to be transferred to the common terminal 30, the guard terminal 40, or another generation of generation terminal 10. The key input data is data input by the user, and are data related to the entrance control signal for the common entrance, an address of another generation (destination address associated with call and call), and the like. The detection signal data is signal data generated from a detector such as a crime prevention, gas, or fire connected to the generation terminal.

Such data may be temporarily stored in the transmission buffer unit 11, but separately stored in a separate storage space. That is, the transmission buffer unit 11 is divided into an area for storing audio data, an area for storing video data, and an area for storing key input data.

Data stored in the buffer unit 11 is output by the data moving unit 12 according to a predetermined format. That is, the data moving unit 12 sequentially outputs or synthesizes the data temporarily stored in the buffer unit 11. For example, the data moving unit 12 may output audio data in order first, and then output video data sequentially (output data sequentially), or may mix and output audio data and video data ( Synthesize data and output).

When the data moving unit 12 sequentially or synthesizes the data temporarily stored in the buffer unit 11, it is preferable that the data moving unit 12 add identification data to a portion where each data starts or ends.

That is, in the case of outputting audio data first and then outputting image data (sequential output), the identification data indicating audio data is included in front of the audio data for output, and after outputting all the audio data, the identification data indicating video data. After including the image data are sequentially output. If the audio data and the video data are synthesized out of order, the identification data may be included in front of each data to be output.

As described above, data output from the data moving unit 12 is converted into an analog signal by the D / A converter and output. This analog signal is transmitted to the connection controller 20 through two wires. In this way, the data input to the access controller 20 is transmitted to the corresponding destination through the analysis process. That is, the access controller 20 finds the destination address and transmits the data to the common entrance terminal 30, the guard terminal 40, or another terminal 10 through the corresponding port.

Meanwhile, the generation terminal 10 includes a receiving module for processing data input from the connection controller 20, wherein the input data are data transmitted from the connection controller 20 through two wires. .

Data input from the connection controller 20 through the two wires are analog signals. Therefore, first, the A / D converter 14 included in the receiving module is converted into digital data and output.

The output digital data are separated into audio data, video data and key input data and various sensing signal data by the data separating unit 15. This separation can be performed because, as described above, identification data for identifying each data is included. That is, the data separator 15 may separate and output the data by referring to the identification data included in the input data.

The data separated and output from the data separator 15 are separated and stored in the reception buffer unit 16. The data stored in the reception buffer unit 16 may be output to the speaker according to the determination and processing of the controller (not shown). The image data stored in the reception buffer unit 16 may be output to the LCD. Meanwhile, if there is a key input and detection signal stored in the reception buffer unit 16, the control function and signal processing may be performed.

The generation terminal 10 including the transmission module and the reception module as described above may perform access control by performing data communication with the common entrance terminal 30 under the control of the connection controller 20. Therefore, the common entrance terminal 30 is also connected to the communication network of the access control system constructed with two wires, specifically, it is connected with the connection controller 20 by two wires.

Since the common entrance terminal 30 transmits and receives data with the connection controller 20 through two wires, the common terminal 30 includes a transmission module and a reception module included in the generation terminal 10. Since the transmission module and the reception module included in the common entrance terminal 30 are the same as the transmission module and the reception module included in the generation terminal 10 described above, description thereof will be omitted. However, when the separated key input signal is the common door opening / closing signal, a control unit (not shown) which may be included separately may receive the key input signal to open and close the common door.

Data communication between the common entrance terminal 30 and each generation terminal 10 is performed by the relay of the connection controller 20. The connection controller 20 is connected to the generation terminal 10 and the common entrance terminal 30 in two lines, respectively, to control data communication between each other.

On the other hand, the terminal controller 40 for the guard room may be connected by two wires to the connection controller 20. That is, the guard room terminal 40 is connected to the connection controller 20 by two wires may transmit and receive data with the generation terminal 10 and the common entrance terminal 30. By configuring in this way, it is possible to receive an abnormal signal generated by a detector such as a crime prevention, gas, fire, etc., which is separately connected to the terminal for generation in the guard room, and can call by calling the terminal for generation. It is possible to check and call the image received from the terminal for the common entrance, and also to control access. Since the guard terminal 40 also transmits and receives data with the access controller 20, the guard room terminal 40 includes a transmission module and a reception module shown in FIG.

The connection controller 20 as described above is connected to the generation terminal 10, the common entrance terminal 30 and the guard room terminal 40 in a one-to-one manner through the port. In addition, the connection controller 20 includes the configuration shown in FIG. 3 to control data communication between terminals.

That is, the connection controller 20 includes an A / D converter 21, a data analyzer 23, and a D / A converter 25 as shown in FIG. 3.

The A / D converter 21 converts analog data input from the generation terminal 10, the common entrance terminal 30, and the guard terminal 40 through two wires and outputs the digital data.

The digital data output from the A / D converter 21 is analyzed by the data analyzer 23 and output to the corresponding port. That is, the data analyzer 23 analyzes the converted digital data to find a destination address. The destination address may be determined through data input using a keypad of each terminal, or may be determined through data generated and transmitted when data is transmitted from each terminal.

After finding the destination address, the data analyzer 23 outputs the digital data to the corresponding port. This digital data is converted into analog data by the D / A converter 25 and outputted so that it can be transmitted through two lines. That is, the D / A converter 25 converts digital data output from the data analyzer into analog data and transmits the analog data to the corresponding terminal through the two wires. Since the destination address is one-to-one with each port, digital data may be transmitted to the corresponding terminal.

If the communication network of the access control system is configured according to the above-described configurations, data communication can be performed using existing two wires without removing the wiring already formed in the apartment, and consequently, access to the common entrance with two wires. Can control and perform unmanned security functions.
