In general, a tele remote control device is a device that remotely controls a control object by a control signal input through an external telephone, detects a surrounding situation, and outputs it through the external telephone. It is a device which makes a telephone call to the installed place, and can remotely control the electronic goods used at home by the tele remote control device, or can grasp | ascertain the state etc. around the remote control device.

FIG. 1 is a schematic block diagram of such a tele remote control apparatus. Referring to FIG. 1, the tele remote control apparatus 10 may include a voice database (DB) 13 and a telephone line for outputting a guidance message to a user. And a telephone line interface unit (I / F) 11 for interfacing with a power source and a power source interface unit (I / F) 12 for interfacing with a power source.

As such, the tele remote control device must always be in standby state in preparation for a call from the outside due to its operation characteristic, so that a certain amount of power must be supplied at all times. Since it has a structure to operate by receiving power, a separate adapter must be added when the tele remote control device is installed, and there is a disadvantage in that the tele remote control device cannot be used if there is no adapter or electricity goes out.

In addition, there is a method for supplying power by applying a battery in the tele remote control device to compensate for these disadvantages, but in this case, the battery is quickly discharged due to the operation characteristics of the tele remote control device, so that a separate battery for charging the battery A charger is needed, which is a more complex configuration than an adapter.

Therefore, the part that can utilize the tele remote control device was limited.

For example, it is difficult to apply the tele remote control device to a security device that must be operated at all times. In order to apply the tele remote control device to a security device, a power supply other than the adapter may be used. It had to be equipped with a separate battery in preparation.

That is, in the case of the conventional tele remote control device must be provided with a separate adapter for power supply, if the power is lost, the tele remote control device loses its function and does not apply to applications requiring reliability, or There was a disadvantage of having a battery and a charger for an auxiliary power supply.

Therefore, in order to solve such a problem, the present invention eliminates the unreliable element generated when power is extinguished by adding a self-power generator that generates power by a ring signal applied through a telephone line inside the tele remote control device. It is an object of the present invention to provide a tele remote control apparatus for increasing the reliability of the apparatus and facilitating the installation.

In order to achieve the above object, the tele remote control device provided in the present invention includes self power generating means for generating an operating power of the tele remote control device in response to a ring signal input through a telephone line.

And a telephone line interface unit (I / F) 120 for generating a power source for operating the remote control device in response to a ring signal input through the telephone line instead of the conventional power interface unit. 150).

And an internal block and a detailed circuit for the tele remote control device. Referring to FIGS. 3 and 4, the self power generator 150 includes a ring detector 102, a battery 103, and a driving power source. It includes a generator 151, and generates a power source for operating the tele remote control device by the control of the microcomputer 101 in the tele remote control device.

The battery 103 is configured as a small rechargeable battery, and supplies power for the initial operation of the microcomputer 101 to the microcomputer 101 by the control of the ring detector 102, and the ring detector 102. Is composed of an optocoupler including a photodiode (PD) and a phototransistor (OPT01). When the photodiode (PD) detects a ring signal input through a telephone line and emits light, the phototransistor (OPT01) Is turned on to transfer the power of the battery 103 to the microcomputer 101 to operate the microcomputer 101.

On the other hand, the driving power generation unit 151 generates a driving power to drive the tele remote control device by leveling up the voltage input through the telephone line by the hook-off signal generated in response to the ring signal. In order to drive the tele remote control device and to charge the battery, the first switch unit 104, the constant current unit 105, and the DC converter 106 are included.

The first switch unit 104 is 'on' by the hook-off signal to form a power transmission path between the telephone line and the constant current unit 105, and 'off' by the hook-off signal to the telephone line and The power transmission path between the constant current units 105 is blocked. That is, only when the ring signal is detected and the hook-off signal of the telephone is generated, the driving power of the tele remote control device is generated by the current transmitted from the telephone line.

In addition, the constant current unit 105 is a device for constantly controlling the current input through the telephone line, as shown in Figure 4 controls the transistors (TR5, TR6) by the amount of current flowing through the resistor (R16). In order to allow a constant current to flow, in addition to such a configuration, all conventional constant current circuits can be applied, and the constant current unit 105 can be used when the tele remote control device according to the present invention consumes a lot of current or an external message. In order to remove the sound distortion caused by the change of current, the voice is used to comply with national standards. If the current consumed by the tele remote control device is small or the current fluctuation is small, the constant current is used. The section 105 can be deleted.

On the other hand, the DC converter 106 is configured by using a step-up (Setp-up) IC that is generally used to increase the level of the power supply, and the voltage of the telephone line constant current through the constant current unit 105 Level-up to generate drive power for driving the tele remote control.

When the ring signal is input from the outside, the microcomputer 101 initially driven by the power applied from the battery 103 drives the tele remote control device when a hook-off signal is generated in response to the ring signal. It generates a control signal for generating a drive power to be delivered to the drive power generator 151.

In addition, the switch SW1 is 'on' to form a power transmission path so that the power of the battery 103 is applied to the microcomputer 101 even in the off period of the ring signal, and the driving power generation unit 151 When the driving power is generated, the switch SW1 is turned off to block the power transmission path.

The overall operation of the tele remote control device by the power control method will be described with reference to FIGS. 3 and 4 as follows.

3 and 4, the tele remote control device includes an in-use detector 107 and a telephone line signal processing unit, which are general components of the tele remote control device, in addition to the self-power generation unit 150. 108, DTMF detector 109, hook-on signal detector 110, voice generator 111, voice detector 112, extension connection control unit 113, display unit 114, key input unit 115, data The transmitter / receiver 116 and the temperature sensor 117 are configured. First, a case in which no ring signal is generated from the outside will be described. In this case, the tele remote control device does not perform any operation, and the battery 103 ) Is not applied to the microcomputer 101, the microcomputer 101 is in the 'off' state, the battery 103 is in a state without any discharge element.

On the other hand, when a call is received from the outside, the optocoupler of the ring detector 102 starts to operate. The voltage of the battery 103 is charged to the capacitor C4 through the resistor R2 and the transistor OPT01. The transistor TR3 and the transistor TR2 are connected to each other, and the voltage of the battery 103 is applied to the microcomputer 101 through the transistor TR2 to operate the microcomputer 101.

Then, the microcomputer 101 first transmits the power of the battery 103 to the microcomputer 101 by first turning on the transistor TR3 with the output terminal OUT2 'high'. It forms a power transmission path, which is to apply the power of the battery 103 to the microcomputer 101 even in the 'off' section of the ring signal that repeats the 'on (on) / off (off)' at a predetermined time interval. .

On the other hand, the microcomputer 101 counts the number of rings through the input terminal IN1, and operates the in-use detector 107 for detecting that the other station picks up the telephone receiver. Here, the extension refers to a case in which a device such as an answering machine that operates automatically when there is no person inside, as well as artificially picking up the handset for a call. In-use) The detection result of the detector 107 enables the tele remote control device to operate even when another station picks up the telephone receiver.

If the count of the counted ring is a preset number or another extension is detected through the in-use detector 107 and is in a hook-off state, the micom ( 101 outputs a 'high' signal through output terminal OUT3 to conduct transistor TR4, through which the current of the telephone line is applied.

As such, the current applied through the transistor TR4 is constant current through the constant current circuit 105 and then level-up via the DC converter 106 to the driving power actually used in the tele remote control device. The driving power output from the DC converter 106 is preferentially supplied to the microcomputer 101 through the diode D3, and to the other circuits in the tele remote control device via the diode D4 and the power supply terminal V1. Then, it is supplied to the battery 103 through the diode (D2) to charge the battery 103.

At this time, the microcomputer 101 outputs an 'off' signal through the output terminal OUT2 to 'off' the transistor TR2, thereby preventing power consumption of the battery 103, The charging current of the battery 103 comes in a limited amount through the resistor R35.

In addition, by outputting a 'high' signal through the output terminal OUT1 of the microcomputer 101, the second switch unit 113 for controlling the extension connection is operated to cut off the extension. To prevent the overlapping of the voice transmitted from the tele remote control device with the voice transmitted from another device, such as when an answering machine is installed, it can be deleted and changed according to the characteristics of the device.

In this way, when the power is supplied to the tele remote control device and all internal circuits operate normally, the tele remote control device is operated by a key operation signal (dial key operation signal) input from the outside.

That is, when the dial key is operated externally, a DTMF signal that is 'striped' is generated, and the DTMF signal is transmitted to the telephone line processing unit IC3 108 through the transistor TR4 and the telephone line processing unit IC3. It is output again through the output terminals (RO1, RO2) of the 108 and is input to the DTMF detector 109.

Then, the DTMF detector 109 extracts the number of the dial key operated by the user based on the signal, and transfers the number to the input / output terminal IN / OUT2 of the microcomputer 101, and the microcomputer 101 receives the microcomputer 101. Voice guidance is provided according to the type of key. To this end, first, the type and timing of the voice to be output to the voice generator IC6 111 through the input / output terminal IN / OUT3 of the microcomputer 101 are indicated. The voice generator (IC6) 111 receives such a command and transfers the contents of the PROM (IC7) storing the voice to be transmitted to the telephone line signal processing unit (IC3) 108 through the output terminal VOICE_OUT, and the voice signal. Is transmitted to the outside through the terminal VL and the transistor TR4 of the telephone line signal processing unit IC3 108.

The transmission of the voice may transmit the contents determined in the PROM IC7 to the outside, but may also transmit the voice around the tele remote control device collected through the voice detector (MIC) 112 to the outside. That is, for example, when the user wants to listen to the sound around the tele remote control device to check whether a thief enters, the children are playing well, or the elderly are uncomfortable.

Then, this series of processes is terminated and a hook-on signal is generated when the user hangs up the telephone receiver or unilaterally hangs up the telephone receiver according to the voice guidance of the tele remote control device. Accordingly, the operation of the tele remote control device is as follows.

That is, when the user puts down the telephone receiver according to the voice guidance of the tele remote control device, the microcomputer 101 may naturally know the time, and thus performs a preset hook-on process. If not, the tele-remote device is operated by a hook-on signal ('band-to-' signal) generated by a telephone switchboard, and the hook-on signal. Is input to the telephone line signal processing unit (IC3) 108 through the transistor TR4, and the microcomputer 101 through the output terminals (R01, R02) and transistor TR8 of the telephone line signal processing unit (IC3) 108. It is input to the input terminal (IN3) of the user informs the microcomputer 101 that the user arbitrarily disconnected to perform the processing for the hook-on (hook-on).

The hook-on processing can be performed by outputting a 'low' signal through the output terminal OUT3 of the microcomputer 101, whereby the transistor TR4 is turned off. off) &quot; to shut down the microcomputer 101 and all circuitry, thereby stopping the operation of the tele remote control device.

On the other hand, the data transmitting and receiving unit 116 includes a plurality of transmission units configured to transmit a plurality of control signals output to the control target to be controlled by the tele remote control device. However, since the power applied through the telephone line as in an embodiment of the present invention is limited, it is not possible to simultaneously drive a plurality of transmission units by the power supply, and to compensate for this, under the control of the microcomputer 101 Operate sequentially.

Therefore, the power VDD (FIG. 5G) applied to the microcomputer at the first time point t1 becomes 'high', and the power charged in the battery 103 is the first time point t1. Gradually decreases.

On the other hand, when a ring signal is generated and power is supplied to the microcomputer 101 as described above, the microcomputer 101 outputs the microcomputer 101 output terminal OUT2 until a hook-off signal is generated (t2). By outputting a 'high' signal through, to set the power supply path of the battery.

When a hook-off signal is generated in response to a ring signal at the second time point t2, the transistors TR2 and TR3 (FIGS. 5A and 5B) are 'off'. Turn off the power output from the battery to the microcomputer, and output a 'high' signal through the microcomputer output terminal OUT3 (Fig. 5f) until the hook-on signal occurs at the third time, the telephone line The voltage input through the input to the input terminal (IN2) (Fig. 5c) of the microcomputer, at this time, also generates a power supply (V1) (Fig. 5h) applied to the other circuit of the tele remote control device.

On the other hand, the battery power is discharged at the first time point t1 at which the ring signal is generated, and is discharged to a second time point t2 at which the hook-off signal is generated, and when the hook-off signal is generated, the telephone It is charged again by the voltage input through the line.
