1. A remote monitor and control system for draining floodgate of a seawall comprising:

a spot control means comprising monitoring cameras for detecting surfaces of an inland water and a seawater respectively, detecting sensors for detecting opening and closing state, water level, water flux, water pressure, rainfall and so on of the draining floodgate and generating a predetermined electric signal corresponding to a detecting volume, speakers for amplifying audio signals transmitted from a spot control room or a remote control room formed at sides of the inland water surface and seawater surface respectively, floodgate opening and closing devices for transmitting information data having a response information on an operation order, opening and closing state information of the draining floodgate, and water level information of the draining floodgate and controlling the opening and closing of the draining floodgate by means of a power, and spot controllers for detecting the opening and closing state and trouble state of the draining floodgate, transmitting the state signal of the draining floodgate to the integrated controller, receiving the operation order of the draining floodgate from the integrated controller, sending the code signal and data to the data interpreter based on his code signal, and conducting two-way communications between the computer having a fixed IP and monitoring cameras and control units;

a control means comprising a data interpreter for interpreting the data received from the spot controller of the spot control means and remote-control the spot control means, an integrated controller for sending the data control signals on the opening and closing, stop and reset of the draining floodgate based on the interpreted data to the spot controller and conducting two-way communications between a computer having the fixed IP of the spot control means and control units, an image remote controller for conducting an internet access function of wire or wireless, a data compression function, a data restoration function, a remote camera control function, a system operation function and so on, and a monitoring device for displaying the images of the monitoring camera of the draining floodgate; and

a remote control means comprising a central management server for receiving processing data, displaying the received data information, and transmitting the operation order to the control means, and an alarm call device for automatically informing emergency situations of a spot monitor or a registered user by means of wire or wireless phone in case of emergency.

2. A remote monitor and control system for draining floodgate of a seawall as claimed in claim 1, wherein the image remote controller comprises a video card portion for compressing the image signals inputted through the monitoring camera in an MPEG-4 conversion manner, an audio card portion for processing the audio signals and having input/output ports of a mike, amp, and speaker for two-way communications, a digital data output portion for transmitting the result signals processed by a CPU through the control signals of the manager to controlling devices, an analog data output portion for converting digital signals processed by the CPU through the control signals of the manager into analog signals and transmitting them to the controlling devices, an emergency signal processing portion for receiving the emergency signal on an access control and a device malfunction and transmitting the emergency signal and the recorded message to the registered manager, a security power controlling portion for controlling turn-on/off of the power so as to maintain the security of the floodgate opening and closing device, a RGB monitor card portion for monitoring and displaying the image signals received from the video card portion in order, a color order screen outputting portion for outputting the image signals received from the video card portion in order according to 4-16 divisions manner, a data comparing portion for separating the data signals inputted by the remote control means and sending them to the spot controller so as to control the spot controller, a hub for mixing the communication signals inputted by the power controller or the draining floodgate controller and sending them to the remote control means, a MPEG encoding/decoding portion for supporting a MPEG4 480/240F for conducting compressing, restoring, and storing all data of the image remote controller, a CPU 242 for sending and receiving various data among each element of the image remote controller and controlling each element over all, and a Codec portion for sending the data through the remote controller after the encoding of the data in the CPU, receiving the data of the remote control means, and transmitting it to the CPU.

3. A remote monitor and control system for draining floodgate of a seawall as claimed in claim 1, wherein the spot controller servers to call out the control room, the remoter control room or the monitor according to the state of the draining floodgate in real-time,

4. A remote monitor and control system for draining floodgate of a seawall as claimed in claim 1, wherein a camera state, lens state, lamp state, floodgate opening and closing state, and urgent message signals and so on can be inquired and controlled by means of the remote control or network.

5. A remote monitor and control system for draining floodgate of a seawall as claimed in claim 1, wherein the data interpreter comprises a data comparator for interpreting the data received from the spot controller and a microcomputer for preventing a data contact between peripheral units and controlling remotely them over all.
