Hereinafter, a specific embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.

The central processing unit 10 outputs the first control signal CTRL1, which is a transmission / reception enable signal of the first and second line transceivers 24 and 26, to the Z terminal of the multiplexer 22. The multiplexer 22 receives the first control signal CTRL1 and transmits / receives an enable signal input terminal of the first line transceiver 24 and the second line transceiver 26 through a Z0 output terminal and a Z1 output terminal. , TXE). The first control signal CTRL1 has a state of 1 and a state of 0. When the first control signal CTRL1 is input to the first and second line transceivers 24 and 26 in a state 1, the first and second line transceivers 24 and 26 are converted into a data transmission mode. When the first control signal CTRL1 is input to the first and second line transceivers 24 and 26 in a zero state, the first and second line transceivers 24 and 26 are converted to a data reception mode. Thus, the line transceivers 24 and 26 are always in a state capable of transmitting and receiving data. When the first and second line transceivers 24 and 26 are in the data transmission mode, data is input from the central processing unit 10 to the input / output terminals X and Y of the multiplexer 22. At this time, the central processing unit 10 transmits the second control signal CTRL2 to the fifth control signal CTRL5 to the control signal input terminal INH of the multiplexer 22 in order to distinguish whether the data is passage guard room data or main control room data. , A, B, C) Input / output terminal connection states according to the second control signal CTRL2 to fifth control signal CTRL5 of the multiplexer 22 are shown in Table 1 below.

In Table 1, X1, Y0, Z0: connection terminal with the first line transceiver 24

X1, Y1, Z1: connection terminal with the second line transceiver 26

×: Regardless of input status

INH, a, b, c: control signal input terminal of the multiplexer 22

Referring to Table 1, when the second control signal CTRL2 of the central processing unit 10 is in the zero state output, and the third control signal CTRL3 and the fifth control signal CTRL5 are all in the zero state, the multiplexer 22 is used. The output terminal of X0 terminal, Y0 terminal, and Z0 terminal are connected. Therefore, the data DATA1 and DATA2 output from the central processing unit 10 are input to the X input / output terminals and the Y input / output terminals of the multiplexer 22 and output to the X0 terminal and the Y0 terminal of the multiplexer 22. The first line transceiver 24 receives the data DATA1 and DATA2 and transmits the data DATA1 and DATA2 through the inter-guard room data bus lines L1 and L2.

When the second control signal CTRL2 of the central processing unit 10 is in the zero state output, and the third control signal CTRL3 to the fifth control signal CTRL5 are all in one state, the output terminal of the multiplexer 22 is the X1 terminal, Y1. Terminal and Z1 terminal are connected. Therefore, the data DATA1 and DATA2 output from the central processing unit 10 are input to the X input / output terminals and the Y input / output terminals of the multiplexer 22 and output to the X1 terminal and the Y1 terminal of the multiplexer 22. The data DATA1 and DATA2 of the second line transceiver 26 are received and the data DATA1 and DATA2 are transmitted through the data bus lines L3 and L4 with the main management office.

In addition, in Table 1, when the second control signal CTRL2 of the central processing unit 10 is output of 1 state, the multiplexer 22 is connected to the internal line regardless of the third control signal CTRL3 to the fifth control signal CTRL5. This is not done. When data from another guard room is received through the first line transceiver 24, the line transceivers 24 and 26 output the received data to the multiplexer 22 via the RXD terminal. The multiplexer 22 outputs the data to the central processing unit 10 when the data is received. The central processing unit 10 receives data through the X1 terminal and the X2 terminal, and searches whether the data is a signal transmitted to itself. The central processing unit 10 outputs a call call signal for the administrator to recognize when the data indicates that the data comes to him and is a call initiation signal. The central processing unit 10 retrieves the call request signal of the manager and outputs the call control signal CTRL6 to the switching unit 34 of FIG. 3 when the signal is detected. The switching unit 34 receives the call control signal CTRL6 and selects and connects a call bus line to be connected with the call circuit in response thereto. The call bus line includes bus lines L5 and L6 connected to the multiple passage guard rooms and bus lines L7 and L8 connected to the main management office.

As described above, the present invention can be applied to communication circuits with each guard room and the main control room to facilitate communication and data transmission with each guard room and the main control room. In addition, the present invention has the advantage of simplifying the wiring between each communication circuit. In addition, the present invention provides a convenient communication between each communication circuit can easily control the management and operation of each communication circuit installation place, that is, between the management room and the guard room.
