In such an embodiment, the central control device 20 may be referred to as a monitoring device installed in the security guards (ex: secom, caps), the data transmission and reception device 10 is monitored such that the security guards will be in charge of security. When described in such an example by being installed on the object (100, 200, 300) as follows.

First, the detection target (100, 200, 300) in each position, that is, a sensor for detecting the presence of abnormalities such as the front door sensor 31, the back door sensor 32, the safe sensor 33, the fire sensor 34, etc. The unit 30 is 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 transceiver 10 installed at a predetermined position of the monitoring targets 100, 200, and 300.

Accordingly, the signal sensed by the sensing sensor unit 30 is input to the data transmitting and receiving apparatus 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 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.

The control unit 14 analyzes the detected signal as described above to determine the emergency state, and if it is determined that the emergency state, the encoder to transmit the channel number and status data from the detected signal to the central control unit 20 The output is (15).

The encoder 15 converts the input channel number and state data and the unique number data of the monitoring targets 100, 200, and 300 into a signal form for encoding and transmitting the encoded data.

Thereafter, the data encoded by the encoder 15 is transmitted to the telephone number set in the control unit 14 through the data transmission / reception unit 16.

As described above, the data transmitted from the data transmission / reception apparatus 10 is relayed to the public communication network PSTN through the CT-2 base station BS and transmitted to the central control apparatus 20.

The central control apparatus 20 decodes the data transmitted as described above and converts the data into a data form before being decoded by the decoder 22.

The central control unit 23 analyzes the converted data as described above, recognizes the unique number of the monitoring target (100, 200, 300) to determine which position, and recognizes the state by recognizing the channel number and state data. It will control the operation accordingly.

That is, by determining the state as described above is to proceed with the step of being able to automatically contact the patrol crew, or the fire department in case of fire with a warning display.

On the other hand, the central control device 20 can transmit and receive data when connected to the data transmission and reception device 10 as well as the CT-2 PLUS to the desired monitoring target (100, 200, 300) at the desired time in the central control device 20. It is possible to remotely monitor the monitoring target by command control signal by calling through the service.

In this case, the central control apparatus 20 determines the desired monitoring targets (100, 200, 300), determines the command control data, and then encodes the command control data through the encoder 24 to convert the data into a transferable data form.

Subsequently, the call number of the monitoring target (100, 200, 300) is dialed through the transmission / reception unit 21, and when the call is connected with the data transmission / reception device 10, the data encoded by the encoder 24 is transmitted as call data. The call then completes.

At this time, the data transmitted as the call data includes a command control signal such as a channel number of the data transceiver and whether or not to perform state sensing.

In the data transmission apparatus 10, as in FIG. 4, the operation of the control signal transmitted from the central control apparatus 20 is performed. The call data received through the call signal receiving unit 17 is performed. It is decoded by the decoder 18 and converted into the original data form.

The control unit 14 reads the converted command control signal as described above to determine the corresponding channel number of the input channel 11 and whether or not the command is executed, so as to read the detection signal for the channel of the corresponding number through the input channel control unit 12. Output a control signal.

Subsequently, the input channel controller 12 detects the detected signal input through the channel of the corresponding number as described above by the input signal detector 13 to detect the detected signal, and determines the detected signal by the controller 14 to control the central control. The apparatus 20 is connected to the central control apparatus 20 through the CT-2 service network and transmits the result thereof.

In this way, the central control apparatus 20 recognizes the data transmitted from the data transmission / reception apparatus 10 to recognize whether the data transmission / reception apparatus 10 is operating normally as well as the status of the current monitoring targets 100, 200, and 300. In the state connected with the data transmitting and receiving device 10, the control signal data can be output to remote control.

In addition, as shown in FIG. 4, the data transmitting / receiving apparatus 10 detects an abnormal signal from the sensing sensor unit 30 or detects a detection result every set time except for a call from the central control apparatus 20. By transmitting to the central control device 20 can be informed that the normal operation is made.

In addition, even if it is not a control method for making a phone call according to the conditions as described above, always call the central control unit 20 from the data transmission and reception device 10 to maintain an on-line state through the CT-2 service network. Real time control is possible.

When real-time control is executed as described above, the data transmission / reception apparatus 10 collects, in real time, environmental data such as voltage, current, temperature, and humidity from each detection sensor unit 30 and transmits the data to the central control apparatus 20. Therefore, when the central control device 20 receives such data and is applied to the air conditioner installed in the monitoring targets (100, 200, 300), it may be able to control and monitor its own temperature and humidity value in real time in the central control device (20). have.

In this way, the data information transmitted from the monitoring targets 100, 200, and 300 are stored in the data storage unit 26, whereby the time information and the place can be searched later.

In this way, as well as security companies, the sensor is installed in a large number of devices distributed outside, such as a vending machine, and connected to the data transmission and reception device 10, the quantity and sales of goods in the vending machine from the central control device 20 In addition, centralized monitoring of theft and theft may be possible.

As described above, by allowing the data to be transmitted using the existing CT-2 service network as it is, the system can be constructed at the convenience of circuit use and low cost, and the convenience of system maintenance and repair can be provided. There is an effect that becomes possible.

In addition, due to the characteristics of the CT-2 service network of the wired / wireless duplex structure connected to the public communication network (PSTN) through a large number of distributed base stations (BS), there is little concern about data loss.

In addition, since the central control unit and the real time control of the always online state can be selected according to the conditions (when a call signal is received, when an abnormal signal is detected, or when a predetermined time has elapsed), it is possible to use a low fee. In other words, monitoring and control are possible.
