Remote power control system and power supply tap

Abstract

According to one embodiment, a power supply tap includes a first wireless reception module which receives a control request which is transmitted from a remote-control terminal by a first wireless signal, a power observation module which is activated in a case where the received control request includes a power information acquisition request, and observes a total amount of power including power supplied to an electric apparatus from a power output module and power consumed by a communication control module, a first wireless transmission module which transmits the observed total amount of power to the remote-control terminal by a second wireless signal, and a switch control module which turns off a switch in a case where the control request received by the first wireless reception module includes a power-off request, thereby shutting off power supply to the electric apparatus from the power output module.

1 . A remote power control system comprising a power supply tap and a remote-control terminal configured to remotely control the power supply tap by a wireless signal, the power supply tap comprising:
 a power input module configured to receive power;   a power output module configured to output the power to an electric apparatus;   a switch disposed between the power input module and the power output module; and   a communication control module configured to wirelessly communicate with the remote-control terminal, the communication control module comprising a first wireless reception module configured to receive a control request transmitted from the remote-control terminal by a first wireless signal, a power observation module configured to be activated when the control request received by the first wireless reception module comprises a power information acquisition request and configured to observe a total amount of power consumed via the power supply tap, the total amount of power comprising power supplied to the electric apparatus from the power output module and power consumed by the communication control module, a first wireless transmission module configured to transmit the total amount of power observed by the power observation module to the remote-control terminal by a second wireless signal, and a switch control module configured to turn off the switch in order to shut off power supply to the electric apparatus from the power output module when the control request received by the first wireless reception module comprises a power-off request, and   the remote-control terminal comprising:   an input module;   a second wireless transmission module configured to transmit the control request comprising either the power information acquisition request or the power-off request, to the power supply tap by the first wireless signal in response to an operation of the input module;   a second wireless reception module configured to receive the observed total amount of power transmitted from the power supply tap by the second wireless signal; and   a display configured to display information relating to the power consumed via the power supply tap based on the total amount of power received by the second wireless reception module.   
   
   
       2 . The remote power control system of  claim 1 , wherein the power observation module is configured to observe either a value indicative of a difference between the total amounts of power before and after turn-off of the switch or a value indicative of the total amount of power after the turn-off of the switch, and the first wireless transmission module is configured to transmit the value observed by the power observation module to the remote-control terminal by the second wireless signal as information indicative of a power saving effect by the turn-off of the switch, if the received control request comprises the power-off request. 
   
   
       3 . The remote power control system of  claim 1 , wherein the first wireless transmission module is activated after the control request is received by the first wireless reception module. 
   
   
       4 . The remote power control system of  claim 3 , wherein a wireless communication between the second wireless transmission module and the first wireless reception module by using the first wireless signal is slower than a wireless communication between the first wireless transmission module and the second wireless reception module by using the second wireless signal. 
   
   
       5 . The remote power control system of  claim 1 , wherein the power supply tap comprises a cell configured to supply power to the communication control module. 
   
   
       6 . The remote power control system of  claim 1 , wherein the remote-control terminal comprises a solar cell module configured to supply power to the input module, the second wireless transmission module, the second wireless reception module and the display. 
   
   
       7 . A power supply tap configured to wirelessly communicate with a remote-control terminal, comprising:
 a power input module configured to receive power;   a power output module configured to output the power to an electric apparatus;   a switch disposed between the power input module and the power output module; and   a communication control module configured to execute wireless communication with the remote-control terminal, the communication control module comprising a wireless reception module configured to receive a control request transmitted from the remote-control terminal by a first wireless signal, a power observation module configured to be activated when the control request received by the wireless reception module comprises a power information acquisition request, and configured to observe a total amount of power consumed via the power supply tap, the total amount of power comprising power supplied to the electric apparatus from the power output module and power consumed by the communication control module, a wireless transmission module configured to transmit the total amount of power observed by the power observation module to the remote-control terminal by a second wireless signal, and a switch control module configured to turn off the switch in order to shut off power supply to the electric apparatus from the power output module when the control request received by the wireless reception module comprises a power-off request.   
   
   
       8 . The power supply tap of  claim 7 , wherein the power observation module is configured to observe either a value indicative of a difference between the total amounts of power before and after the turn-off of the switch or a value indicative of the total amount of power after the turn-off of the switch, and the wireless transmission module is configured to transmit the value observed by the power observation module to the remote-control terminal by the second wireless signal as information indicative of a power saving effect by the turn-off of the switch, when the received control request comprises the power-off request. 
   
   
       9 . The power supply tap of  claim 7 , wherein the wireless transmission module is activated after the control request is received by the wireless reception module. 
   
   
       10 . The power supply tap of  claim 9 , wherein a wireless communication between the second wireless transmission module and the first wireless reception module by using the first wireless signal is slower than a wireless communication between the first wireless transmission module and the second wireless reception module by using the second wireless signal.
