Definitions

  • the invention relates to a remote controller device, and more particularly, relates to a power supply system of a remote controller, which uses a solar cell and a condenser instead of a battery as remote controller power source.
  • a remote controller is used as a convenient means to utilize the electronic appliances.
  • the buttons are properly connected to each command input terminal of a micro controller 2 by means of a data transfer line 3.
  • a micro controller 2 In order to achieve the objective of the system, a micro controller 2 generates a control data signal according to a function of the pressed button, whereby when one of buttons 1 is pressed, then the signal is transmitted through the output terminal of micro controller 2.
  • Output terminal of micro controller 2 is connected to a base of switching transistor 5, and a cathode of infrared light-emitting diode 4 is connected to a collector of switching transistor 5.
  • a switching transistor 5 converts a control data signal transmitted from the micro controller 2 to an infrared light control data for the purpose of the wireless remote control, by means of current flow control of an infrared light-emitting diode 4, which emits infrared light if current flows in it.
  • Fig. 2 is overall mechanical block diagram of remote controller with control buttons 1 and a battery 7 in the prior art.
  • the object of the present invention is to provide a permanent power supply source to a remote controller without an additional expense and the environmental problem.
  • one aspect of the present invention is to use a solar cell 8 as the power source as shown in Fig. 3, but in this case another back up power system should be considered to use in situation when the solar cell cannot generate electric current properly.
  • the present invention uses a condenser 9 as illustrated in Fig. 3, which has a large capacitance such as gold capacitor.
  • rechargeable battery may also be used as a back up power system of the remote controller, it is inadequate and impractical because recharging requires a high electric energy whereas a solar cell, in range of remote controller use, merely generate a low electric energy.
  • a condenser can be charged even with a low electric energy easily, this is the reason why the condenser is used as a back up power system in the present invention.
  • the condenser 9 connected to an output of solar cell 8, recharges electric energy generating from a solar cell 8 whenever light enters and recharged electric energy contained in the condenser 9 is used as a back up power source when there is no light such as a dark place.
  • the condenser 9 can be designed for the cost merit and simplicity as a back up power system, it has a problem that a condenser cannot supply the electric energy to a circuit system of a remote controller for a long period of time in no light condition since the capacity of the charged electric energy in the condenser 9 is not as large as a battery and micro controller 2 consumes it continuously.
  • another aspect of the present invention is to provide a technique that allows much longer usage of the charged energy in the condenser 9. That can be achieved by means of on-off switching power supply line of circuit, using a switch 10 as shown in Fig. 3.
  • the switch prevents the electric energy from flowing into the controller 2 and supply electric energy only when the data line transmits data.
  • the switch10 is designed to convert to the ON state simultaneously as whenever one of buttons 1 is pressed for the purpose of transferring a command input to a remote controller and always stays at the OFF state while the buttons 1 is not being pressed, then there will be no power consumption through load of circuit while button 1 is not in operation, and thus the charged energy in the condenser 9 can last much longer than one without the switch circuit because consumption of charged energy only takes place when the button 1 is pressed for a remote controller operation.
  • the present invention will demonstrate how to design a switch 10, which operates power on-off function simultaneously according to the press of button 1 for the remote controller operation.
  • Fig. 1 is a block diagram of a remote controller system used in prior art.
  • Fig. 2 is an overall mechanical block diagram of a remote controller system illustrating the prior art in which batteries are used as a power supply source.
  • Fig. 3 is a block diagram of the remote controller system according to embodiment of the present invention.
  • Fig. 4 is a mechanical diagram of a remote controller system illustrating a solar cell as a power supply source.
  • Fig. 5 is a block diagram of the switch according to embodiment of the present invention, which has two circuit lines in one mechanical switch connecting each line simultaneously but separately when the switch is pressed.
  • Fig. 6 is a detailed block diagram of the remote controller system which is designed accordance with the concept set forth in Fig. 3.
  • Fig. 3 is a block diagram of the remote controller system according to embodiment of the present invention.
  • a circuit design between the prior art and the present invention consist basically the same connection among a micro controller 2, a switching transistor 5 and an infrared light-emitting diode 4, except for a data line 3 which transfer a command of buttons 1, a switch 10 for the on-off power line, a condenser 9 for charge of electric energy and a solar cell 8.
  • the solar cell 8 is used as the power supply source for the present invention.
  • the positive terminal of the solar cell 8 is connected to the positive terminal of the condenser 9, and the negative terminals of the solar cell 8 and the negative terminal of the condenser 9 are connected to each ground terminals of the micro controller 2 and a switching transistor 5 in common.
  • the solar cell 8 is placed on the remote controller case as shown in Fig. 4.
  • the positive terminal of the condenser 9 is connected to a power-input terminal of the micro controller 2 and anode terminal of an infrared light-emitting diode 4 via the switch 10 for the on-off power line.
  • the function of the switch 10 is to convert to ON state simultaneously with press of the buttons 1 for sending a command input to a remote controller, but always stays at the OFF state if the buttons 1 is not pressed.
  • the embodiment of the switch 10 for the above function is illustrated in Fig. 5.
  • the switch 10 consists of two circuit lines where each line is connected separately, whereby when the switch is pressed then both circuit lines simultaneously becomes connected. As a result, if this switch is used for each button of remote controller, one pass of the switch is utilized as a data line that transfers a command of button and another pass of the switch is utilized as a switch for the on-off power line, and thus creating two separated pass line when the button is pressed.
  • Fig. 6 is a detailed block diagram of the remote controller system designed according to the concept set forth in Fig. 3. If a button 11 of remote controller buttons 1 is pressed, the c and d terminals transfer command data to the micro controller 2 and the a and b terminals supply electric energy of a condenser 9 to load of circuit, including the micro controller 2 and the infrared light-emitting diode 4. Terminal a and b are selectively connected by the first switching line 21 when the button 1 is pressed and terminal c and d are also selectively connected by the second switching line 22. The terminal b is connected to solar cells 8 and the terminal is connected to the micro controller 2.
  • terminal a and b become connected and same time terminal c and d also become connected by first and second switching lines 21, 22.
  • the button of remote controller buttons 1 is not pressed and remains at the OFF state, and the charged energy in the condenser 9 is blocked from flowing into the micro controller 2, 4 thus continual consumption of the charged energy no longer occurs.
  • the power supply system of remote controller of the present invention comprises of a solar cell 8 that generates current whenever light exists.
  • the size of the solar cell 8 should be a small enough that it could be mounted on a remote controller case, but must sufficiently generate current in order to supply energy to operate the remote controller without any difficulties.
  • the solar cell that can generate about electric power of 3V ⁇ 10mA should be used.
  • Current generated from the solar cell 8 is charged in a condenser 9 and used as a power source.
  • the condenser 9 should have sufficiently large capacitance, preferably a gold capacitor, to hold the charged energy to use as a back up power source when the solar cell 8 cannot generate current properly such as when there is no light. If a condenser with capacitance of 0.2 farad and the solar cell generating electric energy of 3V ⁇ 10mA is used as a power source, according to the equation.
  • the condenser 9 Even if the condenser 9 is used as a back power source since it contains sufficiently large energy which can operate a remote controller more than 100 times in no light condition, the condenser 9 is connected to the micro controller 2 and the infrared light-emitting diode 4 directly thus the electric energy in the condenser 9 will be reduced slowly and continuously because of current consumption by the micro controller 2. As a result, the condenser 9 will completely drained of energy such that it cannot be used as a back up power if there is no additional current from the solar cell 8 is supplied.
  • a switch 10 for the on-off power line is designed in order to solve above stated problem.
  • the switch 10 is consist of the function that turns to ON state simultaneously as whenever one of the buttons 1 is pressed for a command input to the remote controller, but always remains in OFF State if no buttons 1 has been pressed as described above in detail along with Fig. 3, Fig. 5 and Fig. 6.
  • the electric energy of the condenser 9 will be conserved without consumption as long as there is no pressing of button 1 for remote controller operation because electric energy consumption in a condenser 9 takes place only by press of button 1. Therefore, the method of the present invention prevents drainage of the energy and the condenser 9 can be used as a back up power source for much longer period of time during the no light state.
