Under the control of the central processing unit 9, it communicates with a device to monitor or control and transmits and receives data, monitors whether the data transmission and reception state is good, and at the same time, the second data transmission unit 6 and the data buffer unit ( 5) a monitoring control section 8 for controlling the state data of the monitoring control object so that it can be accurately stored in the data storage section 4;

It is characterized in that the modem 10 is installed between the second data transmission unit 6 and the remote management system 8 and modulates and demodulates various monitoring and control data transmitted and received via a telephone line.

Here, the supervisory control object includes a panel logic controller (PLC), a general system control controller, a computer, a display device, a standalone device, and the like, and typically transmits and receives data by a general or special protocol.

Referring to the operation and effect of the device of the present invention configured as described above are as follows.

First, the controller and the remote management system 11 of the specific devices 1, which are monitoring and control objects, are connected to the communication interface 2 and the modem 10, respectively, through a communication line (i.e., a telephone line), respectively. It has a state where mutual serial communication is possible.

Of course, in the remote management system 11, if the abnormal state is received from the control panel of the various systems or devices (1) after analyzing it through the software, as well as a predetermined telephone number (i.e., a specific emergency call, mobile specified) It is possible to transmit the contents of the occurrence by making a phone call, etc., and to store and output various data necessary for maintenance and remote monitoring and control such as various accident contents and equipment history.

Meanwhile, when an abnormality occurs in one of the monitoring control objects and the monitoring information is transmitted through the communication interface unit 2, the first data transmission unit 3 under the control of the data control unit 7 stores the data. Since the data storage unit 4 stores the contents in itself, the data storage unit 4 transmits the data to the data buffer unit 5 under the control of the monitoring control unit 8. ) Wait for a while or temporarily store it and send it to the second data transfer unit (6).

Therefore, since the second data transmission unit 6 modulates the monitoring information received through the data buffer unit 5 through the modem 10 and then transmits it to the remote management system 11 through a general telephone line. The remote management system 11 can accurately determine the contents (that is, abnormal state) and make a phone call to a predetermined telephone number to automatically deliver the contents. It can accurately recognize various information required for maintenance and remote monitoring and control, such as accident details and equipment history about water, and take necessary measures in a short time.

On the other hand, the remote management system 11 modulates the control data on how to control the device 1 or a newly generated protocol or parameter based on the monitoring signal for a specific monitoring target to modify the general telephone line. When the modem 10 transmits the data to the modem 10, the modem 10 demodulates the data and transmits the demodulated data to the data storage unit 4 through the second data transfer unit 6 and the data buffer unit 5 as opposed to the above. Part 4 stores the received data in itself and transmits the data to the controller or control panel of the controlled object through the first data transmission part 3, the communication interface 2, and the telephone line. The device or device is automatically controlled in response to the control signal of the remote management system 11 as well as automatically changed to a remote parameter or protocol if necessary.

Of course, in the above description, each unit generates a control signal so as to communicate with the device 1 to be monitored or controlled through a predetermined control program and transmits and receives data, and at the same time monitors whether the data transmission and reception state is good. 9), the first data transfer unit 3 and the data storage unit 4 is controlled by the data control unit 7 under the control of the central processing unit 9, the data buffer The control section 5 and the second data transmission section 6 are controlled by the monitoring control section 8 under the control of the central processing section 9.
