The present invention is characterized in that the control means 3 further comprises a load detecting unit 39 on an output side of the relay switch 41 to detect a load due to the operation of the electronic appliance, and the second MPU 42 recognizes that the electronic appliance is operated only when the load detecting unit 39 detects a load, and counts an actual operating time using the clock signals generated by the clock generating unit 36.

The present invention is characterized in that the control means 3 transmits the remaining operating time of the power plug 2 and ON/OFF status information of the power to the remote controller 1 in a wireless manner, thus allowing a user to monitor the information through the display unit 12 of the remote controller 1. Further, the present invention is characterized m that the control means 3 transmits a predetermined alarm signal to the remote controller 1 when the remaining operating time is less than a predetermined time, thus outputting an alarm through the signal tone generating unit 13 of the remote controller 1. Further, reference numerals 33 and 34, which are not described, represent a transmission power control unit for controlling a drive power supplied to the wireless transmitting unit 31, and a reception power control unit for controlling a drive power supplied to the wireless receiving unit 32, respectively. In the meantime, the control means 3 is implemented to exchange information with a terminal unit 5, such as a telephone provided in home, so that parents can access the terminal unit 5 from a remote place and then remotely controls the control means 3, thus enabling the operating time of the plug 2 to be controlled. The operation of the present invention having the above construction is described below. First, the user inserts the plug 2 of an electronic appliance equipped with the control means 3 into an outlet to allow a drive power to be supplied to the second MPU 42 The second MPU 42 is m a standby mode for a certain period when the drive power is initially supplied. For the certain period, the user registers a unique code of the remote controller 1 in the control means 3. The registration of the unique code is performed as the user presses a specific registration key provided on the key unit 11 of the remote controller 1. If the user presses the registration key, the first MPU 20 having recognized the pressing of the registration key transmits the unique registration code of the remote controller 1 to the control means 3 through the wireless transmitting umt 15. The second MPU 42 of the control means 3 stores the unique registration code transmitted from the remote controller 1 in the memory 35, compares a signal received by the wireless receiving unit 23 after the unique registration code with the registration code stored in the memory 35, determines whether the received signal and the registration code are identical with each other, and then uses the received signal as a valid signal. In the meantime, the second MPU 42 having received the unique registration code from the remote controller 1 transmits a response signal to the remote controller 1 again through the wireless transmitting unit 31. When receiving the response signal from the control means 3, the first MPU 20 of the remote controller 1 outputs a message indicating that the unique code of the remote controller 1 is registered in the control means 3 through the display unit 12 while driving the signal tone generating umt 13 to output a predetermined confirming tone through the speaker 14, thus enabling the user to confirm the confirmmg tone and the message- As described above, if the user manipulates numeric keys provided on the key unit 11 to set the operating time of the electronic appliance and then presses a specific key after the process for registering the unique code of the remote controller 1 has been completed, the first MPU 20 transmits the information of the preset operating time to the control means 3 through the wireless transmitting unit 15. The second MPU 42 of the control means 3 stores the preset operating time information received from the remote controller 1 in the memory 35, performs real-time counting using synchronous clock signals generated by the clock generating unit 36, and then outputs a control signal to shut off the power supplied to the electronic appliance to the power control unit 40 when a counted value is identical with the preset operating time stored in the memory 35. The power control umt 40 turns off the relay switch 41 connected to the power line at one end of the plug 2 by turning off the transistor Ql in response to the control signal output from the second MPU 42, thus shutting off the power supplied to the electronic appliance. Further, the second MPU 42 of the control means 3 outputs an alarm signal to the remote controller 1 when the counted remaining operating time of the electronic appliance less than a predetermined time (for example, five minutes) The first MPU 20 of the remote controller 1 drives the signal tone generating unit 13 in response to the received alarm signal to output a predetermined alarm, so that the parents confirm the remaining operating time of the electronic appliance, thus allowing their child to terminate the operation of the electronic appliance. By the above-described function, a problem can be prevented in that, as the power of the electromc appliance, such as a computer, is unexpectedly turned off, programs of the computer may be damaged. Further, the control means 3 is equipped with the speaker capable of outputtmg an alarm, so that the child using the electromc appliance personally hears the alarm and turns off the electromc appliance. Through the above operation, the parents control their child to suitably control the time spent using a computer, a television, a video game machine, etc., thus allowing the child to have a free time while concentrating on studies In the meantime, the load detecting unit 39 of the present invention detects the status of a load according to whether the electronic appliance is operated, and transmits the detected information to the second MPU 42. The second MPU 42 counts the actual operating time in real-time using the clock signals generated by the clock generating unit 36 only when the operation of the electronic appliance is detected by the load detecting unit 39. If the operation of the electronic appliance is not detected by the load detecting unit 39, the second MPU 42 does not count the operating time any longer and stops the counting. Further, if an abnormal fluctuation occurs on the AC power input to the plug 2, the abnormality of the power is detected by the low voltage control unit 37 and the detected information is provided to the second MPU 42. The second MPU 42 recognizes the low voltage state of the input power, stores actual operating time data obtained at the time of recognition in the memory 35, and is then reset. After the reset, the second MPU 42 continuously counts the remaining operating time on the basis of the actual operatmg time stored in the memory 35 to control the supply of the power to the power plug 2. The second MPU 42 provided in the control means 3 transmits the remaining operating time information at the time of counting the actual operating time and current ON/OFF status information of the electronic appliance to the remote controller 1, thus enabling the user (parents) to visually confirm both the preset time to turn off the operation of the electronic apphance and the current operating status thereof through the display unit 12 provided on the remote controller 1. In the meantime, the control means 3 provided m the present invention can be constructed to communicate with the terminal unit 5, such as a telephone placed in the home, in a wireless manner. Through the above construction, the user accesses the terminal unit 5 outside of the home, not in the home, and then remotely controls the control means 3 through the terminal unit 5, thereby setting and changing the operating tone of the electronic appliance.
