The microcomputer 11 holds a user password and a ring signal wait count value for user authentication, and includes a user password and a ring signal wait count updating means.

The dial-up lamp control device includes a relay switch for turning on and off a driving current of a home lighting lamp connected to an AC power source; A relay driving coil (RCO) for exciting the output of the relay driving unit operated by the control of the microcomputer to start the relay, and switching the lamp lighting current by maintaining the exciting state with the holding current output of the state maintaining unit; A relay driver 15 for communicating with a user through a telephone line and supplying a starting current to the relay driving coil RCO as a control signal of the microcomputer that controls the user in response to the user's selection; A state holding unit 16 for supplying a holding current to the relay driving coil in response to the control signal of the microcomputer in the excited state of the relay driving coil RCO to maintain the excited state at a low voltage; It is characterized by including.

In more detail, the dial-up lamp control apparatus includes a relay switch (RSW) for turning on and off the AC driving current of the home lighting lamp (LAMP); A relay that operates the relay by a starting current provided in response to the output signal c1 of the microcomputer 11 to supply a lamp driving current, and maintains an excitation state with a holding current provided in response to the control signal c2 of the microcomputer 11. Drive coil (RCO); A relay driver 15 for communicating with a user through a telephone line and supplying a relay starting current to the relay driving coil in response to the output signal c1 of the microcomputer 11 controlled in response to the user's selection; A state holding unit 16 for controlling the microcomputer to supply the low voltage holding current to the relay driving coil RCO to maintain the excited state in response to the control signal c2 in the excited state of the relay driving coil RCO; The relay drive coil (RCO) was configured to include a grounded portion (17).

According to the present invention, the lamp status detection unit 17 may be further installed in the control micom 11 to determine whether the lamp is turned on or off in response to a user request connected through a telephone line.

The relay driver 15 included in the dial-up ramp control device receives the control signal c1 of the microcomputer 11 through the bias resistor R1 at the base and connects the collector resistor R2 to Vcc 12v. )Wow; The emitter was connected to Vcc 12v, the base was connected to the bias resistor R3 and the first transistor collector resistor, and the second transistor Q2 was applied to the emitter output to one side of the relay drive coil RCO. .

When the control signal c1 is supplied to the base through the resistor R1 as a high signal, the first transistor is saturated so that the output of the bias resistor R3 flows to the collector resistor R2 and a low voltage is applied to the second transistor base. When the base voltage is low, the second transistor is saturated, and the current of emitter Vcc 12v is applied to the relay drive coil RCO as the second transistor collector output. The diode D2 blocks the starting current from being discharged to the zener diode JD ground when the second transistor is turned on. In the embodiment, the current supplied to the relay drive coil RCO at Vcc 12v is 200 mA. When the control signal c1 changes to a low signal, the first transistor is turned off, and as a result, a high voltage is applied to the second transistor base, so that the second transistor is turned off to cut off the current applied to the relay driving coil.

The state maintaining unit 16 receives the control signal c2 of the microcomputer 11 to the base through the bias resistor R4 and receives the collector Vcc voltage through the emitter decompression resistor R5 and the diode D2. A third transistor (Q3) applied to one side of the RCO; The constant voltage cathode ground zener diode JD was connected to the output of the pressure-sensitive resistor R5 and connected in parallel to the buffer capacitor C1.

The ground unit 17 is configured to ground the other end of the relay driving coil RCO through which the start current and the sustain current are supplied by connecting one end to the second transistor collector and the third transistor output diode D2 through the diode D3. .

When the microcomputer control signal c2 is a high signal, the third transistor Q3 is turned on so that the collector Vcc 5v current is applied as a 3v holding voltage to one side of the relay driving coil RCO through the emitter decompression resistor R5 and the diode D2. . The relay driving coil RCO is installed between the input diode D2 and the ground diode D3 to which the holding current is applied to maintain the excitation state of the relay driving coil at low voltage. The constant voltage zener diode JD prevents a voltage above the holding voltage from being applied to the relay driving coil RCO, and the capacitor C1 stabilizes the holding voltage. In the embodiment, the excitation state holding current of the relay drive coil is 15 to 25 mA.

The state detector 18 receives the cathode voltage of the ground diode D3 through the connection resistor R6 at the base, and the output of the Vcc connection collector resistor R7 is collected by the microcomputer through the connection resistor R8. The emitter ground fourth transistor Q4 is configured to detect by r1.

When the cathode voltage (0.7 to 1v) of the base ground diode D3 is applied to the base through the resistor R6 in the excited state of the relay drive coil RCO, the fourth transistor Q4 is turned on so that the microcom is a collector resistor. The output of (R7) is detected by the status signal r1. The collector resistor R7 used a large value resistor for the fourth transistor current limit. In the embodiment this resistance is 150 k ohm. The resistor R6 blocks the reverse voltage current of the fourth transistor from being passed to the ground diode D3. The microcomputer interprets the state where the low voltage is detected by the fourth transistor collector as the excitation state of the relay driving coil (RCO). Since the voltage at the coil end is 0v when the relay driving coil RCO is in the device state, the fourth transistor is turned off and the collector voltage is high. When the microcomputer detects the high voltage in the fourth transistor collector, it interprets that the relay drive coil is demagnetized.

Micom is programmed to detect the disconnection of the relay drive coil by utilizing the state inspection function of the relay drive coil. For disconnection detection of the relay drive coil RC, the relay drive coil 15 is controlled by the control signal c1, and the relay drive coil status is inspected while supplying a starting current to the relay drive coil RCO. Upon detecting the coil element state (high signal), the microcomputer interprets this state as the disconnection state signal of the relay drive coil RCO.

The dial-up lamp control device of the present invention configured as described above dials the microcomputer to turn the relay switch (RSW) on and off. The microcomputer 11 controls the relay driver 15 with the control signal c1 in response to the request of the remote user to supply the starting current to the relay driver coil RCO. The relay drive coil RCO is excited by the starting current and the relay switch RSW is turned on. The microcomputer controls the state holding unit 16 with the control signal c2 to supply the low voltage holding current to the relay driving coil RCO, and controls the relay driving unit 15 with the control signal c1 to stop the supply of the starting current. The relay driving coil RCO is kept in an excited state with a low voltage holding current, and the relay switch RSW is kept in an on state. In the relay switch-on state, the microcomputer 11 controls the state maintaining unit 16 with the control signal c2 in response to a request of the remote user to cut off the supply of the holding current applied to the relay drive coil RCO. ) To the off state.

In the exemplary embodiment of the present invention, the control microcomputer 11 applies a control signal c1 to the relay driver 15 when it is turned on, and applies a control signal c3 to the ground part 17 to excite the relay drive coil RCO with a starting current. After 0.8 seconds, the high control signal c2 is applied to the state maintaining unit 16 to supply the holding current to the relay drive coil. After 0.2 seconds again, the control microcomputer 11 applies the row control signal c1 to the relay driver 15 to stop the supply of the starting current.

According to the present invention having the above configuration, the home telephone line is connected to the control telephone line 12, and the main switch terminal of the lighting lamp installed in the home is connected to the relay switch (RSW) terminal.

The usage of the present invention is explained. Make a call to your home from outside your home. The microcomputer 11 counts the ring signal of the telephone. If the ring signal is within the set number of times, the microcomputer 11 does not start the control. When the ring signal reaches the set number, the microcomputer 11 starts the control. In control, the microcomputer allows the user to control the lamp of the home via the telephone line 12 in the remote state. The content of the control is to know the status of the lamp, to turn on the lamp, and to turn off the lamp. In the first stage of remote control, the microcomputer 11 performs user authentication. If the caller is not a registered user during the authentication phase, the microcomputer hangs up and terminates the control to go to the call waiting state. If the caller is a registered user in the authentication phase, MyCom will prompt the user for a selection of home control items. When the lamp control is selected as the home control item, the microcomputer prompts the user to select the lamp control item by voice. When the lamp control content is selected, the microcomputer 11 controls the home lamp through the relay driving unit 15 and the state maintaining unit 16 as shown in FIG. 1, and if the state detection unit 18 is included as shown in FIG. In response to the request, the lamp is turned on or off and whether it is disconnected, and the result is transmitted to the user in a voice message.

The user authentication, the control item selection guide, the selection of the control content designation, the error message and the state description included in these processes are stored in the voice chip 13 as a voice message. As the program progresses, the microcomputer 11 selects the voice message stored in the voice chip 13 as the control signal VS and transmits it to the telephone line 12. The user responds to the microcom's voice message request by pressing a keypad number key and a function key on the phone for options or control commands. The user keypad selection and command codes are included in the control program mounted on the control microcomputer 11. The microcomputer 11 receives a key input signal selected by the user through the telephone line 12 as a dial tone signal. The microcomputer 11 provides the received tone signal to the tone signal decoder 14 for decoding. The code decrypted in the tone signal decoder 14 is delivered to the microcomputer 11 as a kit value. The microcomputer 11 performs control by referencing the returned kit value to the control program.

Example 2

Micom detects and counts ring signals from telephone lines connected in the main loop. When the ring signal reaches the seven times set up in the program, the telephone line is transferred to the call state and control is performed.

The microcomputer selects the 001 voice message from the voice output unit and transmits it to the telephone line, waits for a user response for a certain time, and performs a "user authentication" control if there is a response. If there is no user response for a certain period of time, the operation ends and the ring signal is detected.

001: "Please enter your four-digit password for home control"

After sending the 001 message, MICOM's 'User Authentication' control receives and decrypts the dial tone signal on the telephone line and compares it with the password stored inside.

If the received password matches the stored password, the remote control is performed by the authorized user's control request.If the password is inconsistent or the response key signal is different from the format, the call is terminated and the control is terminated. Return to

Micom's 'remote control' sends 002 voice messages to the telephone line and waits for user response key signals.

002: "Press button 1 for gas control, button 2 for boiler control and button 3 for light control"

After sending the 002 message, the control of the microcomputer detects and decodes the dial tone signal from the telephone line and determines whether the received button signal is 1-3. If it is the number, branch as below. If the number is not found, error is processed and the loop returns to 'main loop'.

If the dial tone signal analysis result is '1' button signal, it calls 'Gas Valve Control' routine.

The microcomputer calls the 'boiler control' routine of the present invention when the dial tone signal analysis results in the button signal '2'.

The microcomputer calls 'light control' routine when the signal of '3' is analyzed.

The microcomputer selects the 030 message from the voice chip 13 and outputs it to the telephone line 12 in the 'light control' routine.

030: "Light control mode. Let me know the status of the light."

The microcomputer checks the state of the light in the state detector 18, and if the light is on, transmits 031 message and 032 message to the telephone line.

031: "Home light is on"

032: "Press the well button to turn off the light"

When waiting for the user's key input and detecting the '#' button signal, it performs 'light out control' through the grounding unit 17, outputs a 033 message to the telephone line, and returns to the 'main loop'. .

033: "The light is off"

The microcomputer checks the state of the light in the state detector 18 and transmits 035 and 036 messages to the telephone line when the light is turned off.

035: "Home light is off"

036: "Press the star button to turn on the lamp"

After waiting for the user's key input and detecting an asterisk ('*') button signal, it performs 'lighting control' through the relay driver 15 and the state maintaining unit 16, and then outputs a 037 message to the telephone line. Return to the main loop.

037: "Light is on"

When the microcomputer detects another button signal in the well sperm button signal or star button signal detection step, the microcomputer outputs a 038 message to the telephone line and returns to the main loop.
