3 is a block diagram showing the configuration of an intelligent water supply and sewage remote monitoring and control system according to an embodiment.

As shown in FIG. 3, when the system of one embodiment basically performs remote monitoring and control of water and sewage as in the past, the field control panel 100 converts data from electrical signals such as infrastructure and transmits it to the central control center 200. To confirm. Then, by controlling the operation operation of the infrastructure according to the operation operation control value of the central control center 200 or the field control panel 100, water and sewage monitoring and control is performed.

In this state, the system according to an embodiment combines the operation of the infrastructure and the like with the IoT function through real-time interworking between the on-site control panel 100 and the central control center 200 when the operation of the infrastructure is controlled in this way. By doing so, intelligent water supply and sewage system remote monitoring and control are performed.

To this end, the system according to an embodiment allows the on-site control panel 100 to differently and integrally control the operation operation of the infrastructure according to the operation operation control values for different operation modes from the PLC controller 110 described above. It includes an MCU (130).

And, in this case, the central control center 200 or the field control panel 100, when the operation mode is the automatic mode, the set value according to the input/output condition of the control target to the MCU 130 as a first operation operation control value. to provide. In addition, when the driving mode is a manual mode, an operation value by an operator is provided to the MCU 130 as a second driving operation control value.

In particular, when the operation mode is the cascade mode, the central control center 200 analyzes the data of the infrastructure including the infrastructure and the sensor unit 120 inputted through the PLC controller 110 and adjusts to a preset control format. Accordingly, a control command is calculated and provided to the MCU 130 as a third driving operation control value.

The on-site control panel 100 is specifically, a sensor unit 120 that collects a plurality of different water and sewage status information, and the central control center 200 by converting the electrical signal of the infrastructure and the water and sewage status information of the sensor unit 120 ), and includes a PLC controller 110 that integrally transmits the operation control values for each of a plurality of different operation modes of the central control center 200 or the field control panel 100 itself to the infrastructure. In particular, the on-site control panel 100 includes an MCU 130 that controls the operation operation of the infrastructure differently and integratively according to a plurality of operation operation control values for different operation modes from the PLC controller 110. For example, when the operation mode is a cascade mode, the on-site control panel 100 is provided with an infrastructure and a sensor unit 120 from the central control center 200 through the communication module of the PLC controller 110 in the MCU 130.

General settings are made in general, the camera part is to select the type of the connected camera part, address is the network address of the selected camera part, and the protocol is LSIS, Modbus, Profibus, etc. You can select the one that matches the part 50, and for communication, you can select among RS-232, RS485, and LAN communication, and for the communication port, select the communication port (Common Port) terminal (COM1, COM2). , ..., COM10), IP address is the camera's IP address, History trend is Live or saved previous data search history, select the date of previous data search, Period is the search date period.

You can choose.

In Analog, Enable is the use of displayed data, String is the data name, Measure is the data unit, the X axis is the coordinates of the X axis to display characters on the screen, and the Y axis displays the characters on the screen. The coordinates of the Y-axis to be performed, Size is the size of the character, Color is the color of the character, Display Status is Text or Trend, and the minimum range is the minimum number of data. , Range Max is the highest value of the data, and Display Time is the time when the X coordinate of the time domain is set among the trend coordinates when displaying the trend.

Enabling of digital input is whether or not the displayed data is used, the string is the data name, the X axis is the coordinates of the X axis to display the text on the screen, the Y axis is the coordinates of the Y axis to display the text on the screen, the size is the size of the character, and the color is the character. Color and effect set the alarm method (fast blinking, slow blinking, screen flicker), and the Display Status is Text or Trend, and the display time is the time among trend coordinates when the trend is displayed. The area X coordinate is displayed at the set time.

The enable of digital output is the use of displayed data, the string is the data name, the X axis is the coordinates of the X axis to display the text on the screen, the Y axis is the coordinates of the Y axis to display the text on the screen, the size is the size of the character, and the color is the character. The color and effect of the alarm set the method of alarm (fast blinking, slow blinking, screen blinking), and the control status is a function that allows the administrator to arbitrarily set the program that selects the control of the control system between ON/OFF.
