The second switch 22 is a traditional electromechanical relay (EMR) which has relatively smaller effect on temperature change.
Although the solid state relay has low power consumption properties, but the temperature changed is very sensitive which is generated by the large current loading, such that the first switch 20 cannot withstand high power output steady. Thus, by the second switch 20 is a traditional relay, the second switch 20 can maintain the multi-ports power monitoring system has the largest current to conduct each the first switch 20 and each the second switch 22 of each the plurality of switches 2 by switching, such that the loading can be operated in a high power efficiency mode, a low power consumption efficiency mode and a turn off mode to achieve the high efficiency and energy-saving effect.
In one embodiment, the definition of low power consumption is that the first switch 20 is conducted and the second switch 22 is not conducted. When the second switch 22 is conducted and the first switch 20 is not conducted, it can be defined as the high power efficiency mode.

Then, the power loading value is compared with the preset threshold value in step S52. When the power loading value is higher than preset threshold value and the switch mode is set as low power consumption efficiency mode, the switch 2 is switched to high power efficiency mode according to the address in step S54. Otherwise, when the power loading value is set as lower than the preset threshold value and the switch 2 is set as high power efficiency mode, the switch 2 is switched to low power consumption efficiency mode according to the address is in Step 56, in which the preset threshold value can be set according to the environment or use habit.

The remote server is communicated with the control module 5 by wireless network through the wireless transmission module 6 and instructs the control module 5 to control the switch 2 that is corresponding to each address. The remote server can output a turn on signal and a turn off signal through the wireless transmission module 6 to the control module 5, in which the turn on signal and the turn off signal will correspond to an address respectively. The control module 5 will control the power output of the switch 2 of corresponded address according to turn on signal and turn off signal respectively.
Furthermore, when the control module 5 receives the turn on signal from the wireless transmission module 6, the switch module 2 is corresponding to the address that is to be conducted to turn on the corresponded electric equipment. When the control module 5 receives the turn off signal, the switch module 2 is corresponding to the address that is to be conducted to turn off the corresponded electric equipment. In addition, the electric output information includes the power loading value of each the plurality of power supply ports 3, total power loading value and average power loading value.

Thus, user can find out the power supply ports 3 that should not be consumed at that time, that is, the user may be forgotten to turn off the electric equipment and let the electric equipment is operated continuously. User can transmit a turn off signal from the mobile device through the remote server to the wireless transmission module 6 to allow that the control module 5 receives the turn off signal from the wireless transmission module 6, and the assigned address of the power supply ports 3 is to be turned, such that the power cannot supply for the power supply ports 3 of assigned address to achieve each the plurality of power supply ports 3 is monitored by the corresponded each address.
