FIG. 3 is a block diagram of the field control panel shown in FIG. 2. FIG.

As shown in the figure, one field control panel 100 controls two motors M1 and M2. However, the present invention is not limited to the number of motors M1 and M2.

Each of the motors M1 and M2 supplies power to the branch breakers SCB1 and SCB2 branched from the main breaker MCB of the field control panel 100, the low voltage relays UVR1 and UVR2, the forward rotation buttons 111 and 113, (112, 114), and electronic overcurrent relays (EOCR1, EOCR2).

The main breaker (MCB) disconnects (trips) when a short circuit or a full load is overloaded and the branch breaker (SCB1, SCB2) disconnects (trips) when the motor M1 or M2 is overloaded. The capacity of the circuit breaker MCB is larger than that of each of the branch circuit breakers SCB1 and SCB2.

The trip state of the main breaker MCB or the branch circuit breakers SCR1 and SCR2 is transmitted to the monitoring controller 200 via the interface 150. [

The low voltage relay (UVR1, UVR2) is a relay which trips when voltage is too low to damage motor M1, M2, so it is prepared for power failure rather than low voltage.

The trip state of the low voltage relays UVR1 and UVR2 is transmitted to the monitoring controller 200 via the interface 150. [

The forward rotation buttons 111 and 113 and the reverse rotation button 112.114 are constituent units for forward and reverse rotations of the motors M1 and M2. The motor M1 and M2 can be rotated in the reverse direction by pressing the reverse rotation buttons 112 and 114 to remove foreign substances and then the normal rotation buttons 111 and 113 can be pressed again to normally operate the motor.

The control states of the forward rotation buttons 111 and 113 and the reverse rotation buttons 112 and 114 are transmitted to the monitoring controller 200 via the interface 150.

The electronic overcurrent relays EOCR1 and EOCR2 are relays used when detecting the overcurrent of the motors M1 and M2. When an abnormality occurs in the motors M1 and M2, the power supplies to the motors M1 and M2 are shut off (Trip).

The trip state of the electronic overcurrent relays EOCR1 and EOCR2 is transmitted to the monitoring controller 200 via the interface 150. [

Also, a level sensor S for sensing the level of the manhole pump is provided in the field control panel 100 to sense the level of the manhole pump as the highest, the lowest, the lowest, (200).

The interface 150 outputs monitoring information to the monitoring controller 200 and receives a control signal from the monitoring controller 200 as a component for input / output to / from the monitoring controller 200.

4 is a block diagram of the monitoring controller shown in FIG.

The monitoring controller 200 includes a microcomputer 210, an interface 220, a storage unit 230, a plurality of display units 242, 244, 246 and 248, and a wireless module 250.

The interface 220 receives inputs of monitoring information from the field control panel 100 and outputs a control signal to the field control panel 100.

The wireless module 250 is a component for wireless communication with the mobile phones 300a, 300b, ..., 300n and wirelessly transmits surveillance text messages to the mobile phones 300a, 300b, ..., 300n, , 300b, ..., 300n by wirelessly receiving control text messages.

The storage unit 230 stores various programs necessary for the operation of the monitoring controller 200 and telephone numbers of a plurality of mobile phones.

The microcomputer 210 executes the program stored in the storage unit 230 and outputs the monitoring information sent from the field control panel 100 to the display units 242, 244, 246 and 248, converts the monitoring information into a text message form, To the plurality of cellular phones (300a, 300b, ..., 300n).

In addition, the microcomputer 210 converts the control text message sent from the mobile phones 300a, 300b, ..., 300n into a control signal and outputs the control signal to the field control panel 100 through the interface 220. [

The display unit is constituted by an LCD and / or an LED and displays monitoring information of the field control panel 100. The trip display unit 242 displays a trip state of the main breaker, a trip state of each branch circuit breaker, Status, and trip status of each electronic overcurrent relay.

The water level display unit 244 displays the water level of the manhole pump station classified into the highest, the highest, the lowest, and the lowest.

The first control indicator 246 indicates the reset of the forward rotation, the reverse rotation, the stop and the electronic overcurrent relay EOCR1 for controlling the first motor M1 and the second control indicator 248 indicates the reset of the second motor M2, and the reset of the electronic overcurrent relay (EOCR2).

The field control panel 100 and the monitoring controller 200 may include a solar cell and may use the solar cell as a power source.

Remote monitoring and control of this configuration will be described as follows.

For example, if the impeller of the first motor (M1), which is in the forward rotation in the field control panel (100), senses that foreign matter has stopped moving and outputs the impulse to the surveillance controller (200), the surveillance controller 246) indicates the stop of the first motor. Based on this, the first motor of the manhole pump station is stopped. And transmits the text message to the storage number of the stored multiple mobile phones 300a, 300b,..., 300n in the storage unit 230 by radio.

The person in charge of the manhole pump station confirms the text message to the mobile phone 300a, 300b, ..., 300n, executes the monitoring and control app and outputs a control signal for rotating the first motor of the manhole pump station to the field control panel for 3 minutes , And then outputs a control signal for forward rotation of the first motor to the field control panel 'to transmit the control text message to the monitoring controller 200 by radio.

The monitoring controller 200 generates a control signal based on the control text message and outputs the control signal to the field control panel 100. The field control panel 100 rotates the first motor M1 for three minutes in response to the control signal, And then the motor is driven normally to rotate the motor normally.

For example, when the water level sensor S of the field control panel senses that the water level of the manhole pump is at its maximum and outputs the water level to the monitoring controller 200, the monitoring controller 200 displays the level of the manhole pump in the water level indicator 244 Is the best condition, and based on this, 'Manhole pump level is the highest level, please take measures.' And transmits the text message to the storage number of the stored multiple mobile phones 300a, 300b,..., 300n in the storage unit 230 by radio.

The person in charge of the manhole pump station confirms the text message to the mobile phones 300a, 300b, ..., 300n, executes the monitoring and control app, and sends a control signal to the field control panel Quot ;, and transmits the control text message to the monitoring controller 200 by radio.

The monitoring controller 200 generates a control signal based on the control text message and outputs the control signal to the field control panel 100. The field control panel 100 simultaneously controls the first and second motors M1 and M2 according to the control signal, So that the water level of the manhole pump can be normally managed.

According to the present invention, it is possible to remotely control the manhole pump station by radio, to detect overload, breaker trip, and high / low water level during power failure and motor operation and to send letters to the person in charge, In addition, all the control functions are provided in the mobile phone of the person in charge, so that the manhole pump can be operated by the mobile phone without arriving at the site.
