In this embodiment, the central control unit 20 may be referred to as a monitoring device installed in security guards (ex; secom, caps), the data transmission and reception device 10 is a surveillance that such security guards will be in charge of security. If the operation is described for example by being installed in the object 100, 200, 300 as follows.

First, the monitoring target (100, 200, 300) to detect the presence or failure of each position, that is, the front door sensor 31, the back door sensor 32, the safe sensor 33, the fire sensor 34, etc. The sensor unit 30 to be installed.

The detection sensor unit 30 installed as described above is connected to each channel of the input channel 11 configured in the data transmission / reception apparatus 10 installed at a predetermined position of the monitoring targets 100, 200, and 300.

Therefore, the signal detected by the sensing sensor unit 30 is input to the data transmitting and receiving device 10 through the input channel 11, wherein the sensing signal input through the input channel 11 is input channel control unit 12 According to the control of the signal input proceeds.

The input signal detector 13 detects the current channel status of each channel by performing a signal detector on the input signal, and informs the controller 14 of this.

The controller 14 re-analyzes status data transmitted from the input signal detector 13 to determine whether it is in a normal state or an emergency state.

In this case, in the normal state, the input channel 11 is monitored in the same manner as described above to continuously determine the current state.

However, when there is an external invader, or when a fire is detected, the corresponding detection sensors 31, 32, 33, 34 output a detection signal.

Accordingly, the sensing signal output as described above is input through the corresponding channel of the input channel 11, and the signal input to the input channel 11 is signal detected through the input signal detector 13.
