System and method for monitoring current
View Patent ↗A system for measuring throughflow of current includes a plurality of monitoring units and an electronic device. Each of the plurality of monitoring units is positioned in a switchboard for monitoring the current flowing through the switchboard and outputting a current signal. The electronic device is electronically connected to the plurality of monitoring units. The electronic device receives the current signal transmitted by the plurality of monitoring units, performs analysis and filtering to isolate and display information as to three-phase current being consumed through the plurality of switchboards.
1. A system for monitoring a current flowing through each of a plurality of switchboards, the system comprising:
a plurality of monitoring units, each of the plurality of monitoring units positioned in a switchboard for monitoring the current flowing through the switchboard and outputting a current signal;
an electronic device, the electronic device electronically connected to the plurality of monitoring units; the electronic device comprising a processing unit and a display unit, the display unit electrically connected to the processing unit;
a receiver, the receiver electrically connected to the plurality of switchboards and the processing unit;
wherein the processing unit receives the current signal transmitted by the plurality of monitoring units, performs analysis and filter to output three-phase current information of the plurality of switchboards to the display unit for displaying;
wherein the three-phase current information at least comprises three-phase current values, the display unit further displays a maximum current value of the three-phase current values to determine whether the three-phase current value is overloaded; and
wherein when the maximum current value of the three-phase current value is within a first preset range, the processing unit determines that the current flowing through the switchboard is within a normal range and sends a first control signal to the display unit to control the maximum current value to be displayed with a first color.
2. The system of claim 1 , wherein the receiver transmits the current signal output by the plurality of monitoring units to the electronic device.
3. The system of claim 2 , wherein the processing unit receives the current signal transmitted by the receiver.
4. The system of claim 3 wherein
when the maximum current value of the three-phase current value is within a second preset range, the processing unit determines that the current flowing through the switchboard is within a near overload range and sends a second control signal to the display unit to control the maximum current value to be displayed with a second color; and
when the maximum current value of the three-phase current value is greater than the maximum value of the second preset range, the processing unit determines that the current flowing through the switchboard is in an overload state and sends a third control signal to the display unit to control the maximum current value to be displayed with a third color.
5. The system of claim 4 , further comprising a notification unit, wherein the notification unit is electrically connected to the processing unit, when the processing unit determines that the maximum current value of the switchboard is greater than the maximum value of the second preset range, the notification unit receives a notification signal and the three-phase current information of the overloaded switchboard output by the processing unit.
6. The system of claim 3 , wherein the three-phase current information further comprises the number of the switchboards, when the three-phase current value displayed by the display unit is overloaded, a position of the overloaded switchboard is determined according to the number of the switchboard.
7. A method for monitoring current comprising:
monitoring a current flowing through a switchboard and outputting a current signal;
receiving the current signal, performing analysis and filtering out three-phase current information; and
displaying the three-phase current information;
wherein the three-phase current information at least comprises three-phase current values, a maximum current value of the three-phase current values is displayed to determine whether the three-phase current value is overloaded; and
wherein when the maximum current value of the three-phase current value is within a first preset range, the current flowing through the switchboard is determined to be within a normal range and sends a first control signal to control the maximum current value to be displayed with a first color.
8. The method of claims, further comprising:
determining whether the current flowing through the switchboard is overloaded according to the three-phase current information; and
sending the received three-phase current information to relevant personnel to notify that the switchboard is overloaded.
9. The method of claim 8 , wherein when the maximum current value of the three-phase current value is within a second preset range, the current flowing through the switchboard is determined to be within a near overload range and sends a second control signal to control the maximum current value to be displayed with a second color.
10. The method of claim 8 , wherein when the maximum current value of the three-phase current value is greater than the maximum value of the second preset range, the current flowing through the switchboard is determined to be in an overload state and sends a third control signal to control the maximum current value to be displayed with a third color.
11. The method of claim 8 , wherein the three-phase current information further comprises the number of the switchboards, when the three-phase current value displayed is overloaded, a position of the overloaded switchboard is determined according to the number of the switchboard.
