Abstract

A power delivery control system includes a main receptacle and a plurality of secondary receptacles. Each receptacle is provided with a conductive member which is connected with a power source line via a respective one of a plurality of electrically-controlled switches. The power source line is connected to a power source. The electrically controlled switches are connected with a control unit for receiving an external electronic signal to bring about a control signal for controlling the electrically-controlled switches which in turn control the power supply between the power source line and the conductive members of the secondary receptacles.

Claims

1. A power delivery control system comprising:

a power strip having a main receptacle having a conductive member and a plurality of secondary receptacles, each having a conductive member;

a power source line connected with the conductive member of said main receptacle;

a plurality of electrically-controlled switches, each connected between said power source line and said conductive member of a respective one of said secondary receptacles;

a personal computer; and

a control unit connected between said personal computer and said electrically-controlled switches for receiving external electronic signals from said personal computer to produce control signals corresponding to the external electronic signals for controlling said electrically-controlled switches which in turn control the power supply between said power source line and said conductive member of each of said secondary receptacles when power is being supplied to said main receptacle.

2. The system as defined in claim 1, further comprising a housing, and wherein said main receptacle, said secondary receptacles, said conductive members, said power source line, said electrically-controlled switches, and said control unit are disposed in said housing.

3. The system as defined in claim 1 further comprising an output-input interface connecting said control unit to said computer.

4. The system as defined in claim 3, wherein said output-input interface is a personal computer RS232 interface.

5. The system as defined in claim 3, wherein said output-input interface is a personal computer USB interface.

6. The system as defined in claim 3, wherein said output-input interface is a personal computer parallel port interface.

7. The system as defined in claim 3, wherein said output-input interface is a personal computer expansion slot.

8. The system as defined in claim 1, wherein said control unit is disposed on an interface card whereby said interface card is plugged into a personal computer expansion slot.

9. The system as defined in claim 1, wherein said control unit has a microprocessor and a drive circuit connected with said microprocessor and said electrically-controlled switches.

10. The system as defined in claim 1, wherein said electrically-controlled switches are relays.

11. The system as defined in claim 1, wherein each of said electrically-controlled switches is a TRIAC.

12. The system as defined in claim 1 further comprising a telephone interface connected with said control unit to enable said control unit to be externally connected with a telephone line.

13. The system as defined in claim 12, wherein said telephone interface is connected with a power supplying device of said computer to facilitate the control of said power supplying device by a telephone key signal.

14. The system as defined in claim 1, wherein said main receptacle and said secondary receptacles are disposed accessibly on a housing of the computer whereby said housing is provided therein with a receiving space;

and wherein said conductive members, said power source lines, said electrically-controlled switches, and said control unit are disposed in said receiving space of said housing.
