1 is a schematic connection state diagram of a remote control apparatus using a wired method.

As shown, it can be seen that the telephone line is connected to the air conditioner (10). The telephone line extends from the telephone 22 and is connected to the air conditioner 10 through the telephone terminal 20. The telephone line extending from the telephone terminal 20 is connected to the interface unit 16 according to the present invention installed adjacent to the main control unit 12. The interface unit 16 demodulates the dial tone signal input through the telephone line, processes the signal, and inputs the signal according to the processing result into the main control unit 12. The interface unit 16 includes a dual tone multi-frequency unit (DTMF unit) for demodulating a dial tone signal input through a telephone line, and a control unit for processing a signal input from the DTMF unit. It is included.

When the user makes a phone call from the outside by using the telephone, the DTMF unit demodulates the signal input through the telephone line, and the control unit interprets the signal according to a pre-programmed situation to process the necessary work. For example, when the user inquires about the operating condition of the air conditioner, the user can inquire the current control status (currently operating or failure occurs) to the control unit of the air conditioner and then output the operating status by voice synthesis. . Obviously, these functions can be changed in various ways using a program embedded in the controller. In the case of using a wire line (telephone line), there is an advantage of controlling the air conditioner located over a wide range by extending the length of the telephone line or the connection line. Although the block diagrams for the control unit, the DTMF unit, the speech synthesis unit, and the like are not shown in FIG. 1, since they operate similarly to the circuit blocks described later in FIG. 3, a detailed description thereof will be omitted with reference to FIG. 3. It works the same except the actual control.

2 is a schematic connection state diagram of a remote control apparatus using a wireless method as another embodiment of the present invention.

As shown in the drawing, a transceiver 19 for transmitting and receiving a signal wirelessly is connected to the telephone terminal 20, and the main board control unit 12 installed in the conventional air conditioner 10 can also transmit and receive a signal wirelessly. The interface unit 18 can be connected. The structure of the interface unit 18 and the transceiver unit 19 will be described later.

Signals input by a user located outside through the telephone are first inputted to the transceiver 19 of the remote control apparatus through the telephone line, demodulated, and then transmitted wirelessly. The transmitted signal is received by the interface unit 18 and then input to a control unit (not shown) in the main board control unit 12 of the air conditioner 10. The control controller outputs a control signal to perform a specific operation according to the input signal. The control unit is programmed to perform the role of the control unit of the conventional air conditioner and the function according to the present invention.

One embodiment of a wireless remote control device including the configuration of the interface unit 18 and the transceiver unit 19 is shown in FIG. 3. Corresponding to the transceiver 19 of FIG. 2 is a telephone terminal 20, a DTMF unit 182, a first control unit 184, a first wireless transmission / reception unit 186, and an interface unit 18. The second wireless transmission and reception unit 190 and the second control unit 192 are applicable. The difference between the wired method and the wireless method is the same except that the first and second wireless transmitters and receivers 186 and 190 and the second control unit 192 are further added in the wireless method, so a detailed description of the wired method using the drawings is omitted. In the drawings, the DTMF unit 182 and the voice synthesizer 188 having the same reference numerals perform the same operation.

Telephone terminal 20 is a means for connecting the telephone line, it is preferable to connect the telephone line 22 and the telephone line in parallel. When a signal is input through a telephone line connected to the telephone line terminal 20, the DTMF unit 182 detects the signal. The DTMF unit 182 detects a dial tone signal of the telephone and demodulates it into a signal corresponding to a specific code (usually a number or symbol assigned to a keypad).

The signal demodulated by the DTMF unit 182 is input to the first control unit 184. The first control unit 184 is for performing a specific operation according to the state of the signal input from the DTMF unit 182, the control program is embedded therein, the operation state of this using the flow chart of FIG. It is explained.

The first controller 184 processes a signal input from a user through a telephone line to output a command signal for operating the air conditioner 10 or to notify the user of an operating state of the air conditioner 10. It generates voice synthesis or buzzer sound. The generated voice signal or buzzer sound is transmitted to the user through the telephone line to inform the operating condition of the air conditioner 10. However, there is a difference in function from the control unit used in the wired method.

In addition, the first control unit 184 requests the password input from the user at the first connection and allows the air conditioner 10 to operate only when the correct password is input. In addition, in order to perform a malfunction detection function for detecting a control state, a predetermined signal is output to the interface unit 18, and the reflected signal is detected to monitor the malfunction. In addition, when at least one air conditioner 10 is installed, it may include a function of assigning an identification code so as to control all the air conditioners installed at the same time. In particular, the identification of the air conditioner is carried out by interconnection with the interface section 18. This is explained later.

The voice synthesizer 188 synthesizes and outputs a specific voice signal according to the control signal of the first controller 184. That is, when the user inputs a command for confirming the operation state or the malfunction state of the air conditioner 10, the voice synthesis unit 188 synthesizes the voice for the corresponding item and outputs it to the user through a telephone line. The user can hear the voice signal and check the operation of the air conditioner. At this time, the DTMF unit 182 does not perform any processing on the voice, and the voice synthesized by the voice synthesizer 188 outputs the voice like a talker of a conventional telephone.

The signal output to control the air conditioner 10 from the first control unit 184 or to process a necessary operation is input to the first wireless transmission / reception unit 186. The first wireless transmitter / receiver 186 modulates a signal into a wireless signal and transmits the signal. The radio signal may be a signal by a conventional radio frequency signal (RF), an infrared signal, or a blue tooth method.

The radio frequency signal is generated using an RF module packaged to have a radio transmission and reception function, and the transmission and reception of an infrared signal can be configured by using an infrared sensor having a light emitting unit and a light receiving unit, and brutus The method may use a transceiver designed to meet the Brutus specification. The blue tooth is a wireless interface proposed by five companies including Ericsson, Nokia, Intel, IBM, and Toshiba, and is a wireless communication protocol that wirelessly connects various mobile devices within a range of about 10 meters using a 2.45 GHz frequency. to be.

The radio signal propagated from the first wireless transmitter 186 is input to the second wireless transmitter / receiver 190 embedded in the air conditioner 10. The second radio transmitter and receiver 190 is a pair of devices capable of transmitting and receiving data in essentially the same frequency band as the first radio transmitter and receiver 186.

The second radio transmitter and receiver 190 demodulates the modulated radio signal and inputs it to the second controller 192. The second controller 192 has a built-in control program and outputs a control signal for operating the air conditioner 10 according to the received signal. The output control signal is input to the control unit 12a of the air conditioner 10 to perform a necessary operation. The second controller 192 maintains a cooperative relationship for controlling the operation of the air conditioner 10 through data transmission and reception with the first controller 186.

4 and 5 are flowcharts showing the operating state of the remote control apparatus of the present invention configured as described above, which will be described based on a wireless method.

Maintain standby with telephone line connected to remote control. At this time, when a user makes a call from outside and a predetermined number of ringing signals are input, the DTMF unit of the remote control device detects this and answers the call. At this time, the remote control device may output a voice signal and output a message for the user to input a password (if set). If the password does not match when the password is set, the remote control device confirms the identity by inputting the password up to a predetermined number of times. If the correct password is not entered, the remote control hangs up by outputting a signal to turn off the phone.

When the correct password is input, the controller (first controller) provides information such as an operation state of the air conditioner using the voice synthesizer and waits for a command from the user. At this time, it is preferable to output a voice prompt so that the user can easily input a command. When the operation command signal for the product (air conditioner) is input from the user, the controller outputs a control signal to operate the air conditioner. The operation command signal may be input by pressing a specific number (preset number) on the telephone.

Alternatively, when a change command of a password is input, the password is updated by receiving a new password, reconfirming and storing the password. These functions can be added to the various functions by changing the built-in programs of the controller. All the dial tones generated when the button of the telephone is pressed are demodulated by the DTMF unit 182 and input to the first control unit 184 for processing. At this time, the command menu is output as a voice using the voice synthesizer 188 so that a user can input a command.

FIG. 5 illustrates a process of setting an identification code to control the added air conditioners when adding a new air conditioner. In this case, in the remote control apparatus of the present invention, the control unit (second control unit) is used in the state of using only one transceiver unit (corresponding to the case of the wireless method) and adding the interface unit 18 to the added air conditioner. Can be used to assign an identifier to In addition, by setting a password associated with the identification code in order to control the operation of the added air conditioner can be operated for safety. The identification code and the password may be configured in software, and in the case of the identification code, it may be configured using hardware such as a dip switch. In this case, information is shared through data transmission with the first control unit 184.

As described above, according to the present invention, the user can be notified of the on / off control, operation and operation state of the air conditioner by using a voice or a buzzer, and a password can be set. Also, the air conditioner is controlled by a wired method or a wireless method. There is an advantage to this.
