Data storing and trend display image monitoring apparatus using image processing board

An image monitoring apparatus using an image processing board, the image processing board connected between a control system and a network video recorder (NVR) and embedded in a camera, the image processing board comprising:

• a digital signal processor (DSP) chip;
• a synchronous dynamic random access memory (SDRAM);
• an external storage unit;
• and
• a plurality of ports including an RS-232/485 communication port, a TCP/IP LAN port, a port for controlling a digital output, a contact output, and an alert, a digital port, an analog input port, an RS-485 communication port, an audio port, and a multipoint control unit (MCU) external input/output port, wherein the image processing board is configured to support various protocols of an external device communicating with the control system through RS-485 communication, a LAN, or a Modbus, wherein data processed by the image processing board is displayed by the NVR on a monitor as a situation including a water level, a temperature, and a pressure, wherein when a dangerous or alert situation occurs, a message is displayed on the monitor or an overall screen of the monitor flickers, wherein the image processing board is configured to simultaneously perform an image processing function and an external device control function, wherein the image processing board is configured to encode an compressed image and input data together with the compressed image and to send the encoded data to the NVR, and wherein the NVR including a decoder is configured to restore the compressed image, and the NVR is configured to display various input data including the temperature and the pressure received from the external device on a lower portion of the monitor.
