It is well known that is being put to practical use.

However, in countries where there is a risk of emergencies such as in Korea, such unmanned lighting devices are quite useful in normal times, but in case of an emergency (exhibition), infrastructure facilities, ports, airports In addition, various lighting devices installed in large buildings, etc. cannot be turned off quickly at the appropriate time, which is expected to cause great damage, and as a result, it is a factor that cannot be drastically converted to unmanned lighting devices.

Therefore, in view of the efficient operation of the unmanned lighting equipment, the present invention allows the unmanned lighting devices to be turned off quickly and instantly when necessary in a country where there is no fear of an emergency. The purpose of the present invention is to provide a remote control circuit of an unmanned lighting device that has been prepared for the convenience of an unmanned lighting device and a countermeasure through a remote control circuit.

Looking at the technical configuration of the present invention made to the above object with reference to the accompanying drawings as follows.

A block diagram of the present invention is shown in FIG. That is, the receiver 1 receives the radio frequency and applies its tuning output to the set / reset circuit unit 2 through a logic element to connect it to the flip-flop 3 and connect this output to the drive control logic circuit 4. The unattended illumination is applied to the photo reset unit 5 according to an increase in the amount of solar radiation while simultaneously applying and turning off the load L connected to the switching transistor S / TR in relation to the output of the ordinary unmanned illumination device B. From the output of the device B to the reset of the set / reset circuit section 2, branching from the output of the flip-flop 3 to the tie 6, and connecting this timer output to the set / reset circuit. It is made by connecting to the reset terminal of the reset circuit unit 2, which will be described in detail with reference to a detailed circuit diagram as a basic embodiment of the present invention as shown in FIG.

The AND logic element AND ₁ is connected to the output side of the wireless paging receiver 1 to receive the radio call signal, and the two input AND logic elements AND ₂ and AND _{3 of the} set / reset circuit unit 2 are connected to the output side. The outputs of the AND logic elements AND ₂ and AND ₃ are connected to the set terminal and the reset terminal of the flip flop 3, respectively, to the NAND logic elements. It is connected to control the load by connecting to the one-side input of the drive control logic circuit (4) consisting of a three-input AND logic element (AND ₅ ) through (NAND ₁ ), branched at the output terminal of the flip-flop (3) time constant The other end of the AND logic element AND ₃ connected to the reset end of the flip-flop 3 by connecting the output of the timer 6 to the AND logic element AND ₄ by delaying it through the timer 6 having AND logic element is connected to the stage set at the same time to lock to the input being via a NAND logic element (NAND ₃₎ to (AND ₂₎ Other forms and connected to the side end while connecting the connection via a picture reset unit (5) of the NAND logic element (NAND ₂₎ is branched at the output of unattended lighting device (B) to the reset terminal of the flip-flop 3 to the 3-input aND with a logic element (aND ₅₎ the picture reset section 5, the three-input aND logic element (aND ₅₎ connected to the reset terminal of said flip-flop (3) connected through a by the drive control The load L is turned off and on by controlling the switching transistor S / TR on and off at the output of the logic circuit 4.

Meanwhile, as another embodiment of the present invention, FIG. 3 illustrates a case where a remote control circuit is configured through a radio frequency.

It connects a plurality of frequency decoders FD ₁ and FD ₂ with reference frequencies set to the radio frequency receiver RR for reliability, and delays the decoding output through the receiver ₁ having the NOR logic element NOR ₁ . A set circuit section (2 ＇) connected to the circuit (D), the output of the electrical delay circuit connected to the inverting input terminal of the voltage comparator (VC ₁ ), and the reference voltage generator (VR ₁ ) connected to the non-inverting input terminal, Connect the output of VC ₁ to the set input of the flip-flop (3 ms), and connect the driving control logic circuit (4 ms) consisting of three input and logic elements to turn off the load according to the output of the flip-flop. A photo reset section 5 'made of a NAND logic element inverted in accordance with the output of the unmanned lighting device B is connected to the reset end of 3 ms.

In addition, as another embodiment of the present invention as shown in FIG. 3 is an example of bonding in the case of an advertising tower, a street lamp, etc. using a commercial power source, not a small power supply used to charge a solar cell as a power source and an operational amplifier. The photodiode PD is connected between the ground circuits between the input terminals of the OP AMP, and the output is connected to the non-inverting input terminal of the voltage comparator VC ₂ so as to be connected to the 3-input AND as one input. The configuration of the control input unit is the same as that of the basic embodiment, and description thereof will be omitted.

At the same time, the present invention forms a drive control logic circuit 4,4 kHz with a 4-input AND and a control unit A having a wireless paging receiver PR described above and a control unit A 를 having a radio frequency signal receiver RR. Is connected to the drive control logic circuit (4 or 4 kHz) with respective inputs, thereby enabling the use of both a radio calling method and a radio frequency method operating as a specific call code.

Unexplained P is a pulse generator to realize flashing of the load.

Looking at the effect of the present invention having the configuration as described above as follows.

The conventional unmanned lighting device B, which charges the solar cell 20 to the rechargeable battery 11 and uses it as an operating power source, charges when the potential difference between the solar cell and the battery becomes solar cell> storage battery (weekly). in contrast, when the solar cell ≤ battery that is if the non-inverting input below the level of the voltage comparator (VC _2), a reference voltage generation section 13 is set to an inverting input terminal of the (overnight) the voltage comparator (VC ₂₎ is operated by the output The unmanned lighting device (B) is operated to turn on the load, so let's look at the basic embodiment of the present invention as shown in FIG.

Here, the unmanned lighting device B will be described as a lighting operation state. When the corresponding code is first transmitted to the wireless paging receiver PR to receive a specific radio call code and is input to the receiver PR, the output terminal of the wireless paging receiver PR continuously for several tens of seconds (typically 20 seconds). When the signal of the "H" level appears and is input to _{one end} of the AND logic element AND ₂ (AND ₃ ) of the set / reset circuit unit 2 through the AND logic element AND ₁ , the output of the flip-flop 3 is output. The output of the NAND logic element NAND ₃ in the "L" level state is inverted to the "H" level state and input to the other end of the AND logic element AND ₂ to realize the set input of the flip-flop 3.

Accordingly, the flip-flop 3 represents the signal of the "H" level at the output terminal, and the signal of the "H" level is inverted in the NAND logic element NAND ₁ so that the three input AND logic element AND of the drive control logic circuit 4 is generated. ₅ ) turns off the load by applying the “L” level at one end to cut off the bias potential of the switching transistor (S / TR) that was in operation.

On the other hand, when the unmanned lighting device B is turned off and then turned on again, two reset circuits are used.

First, the photo reset unit 5 commonly applied to the present invention is in a set state in which the input of the NAND logic element NAND ₂ becomes “L”, that is, during the day when the solar radiation increases (solar cell> storage battery). The NFL logic element (HAND) is reset so that the flip-flop 3 is reset to the reset stage of the flip-flop 3 so that the flip-flop 3 is reset and thus connected to the drive control logic circuit 4 as an input. NAND ₁ ) has its output reversed to the “H” state, but since the output of the unmanned lighting device B is at the “L” level, the load does not turn on but becomes night again and the reset flip-flop 3 is turned on. Lights up in relation to the output of

The second reset path transmits the radio call code described above again, and when the wireless paging receiver PR of the present invention generates the output of " H " level again, the AND logic element of the set / reset circuit portion 2 as described above. One end of (AND ₂ , AND ₃ ) receives a signal of “H” level, but the “H” level of the AND logic device (AND ₄ ) that has passed the delay time is input to the other end of the AND logic device (AND ₃ ). The flop 3 receives a reset input and the reset output then acts to turn off the load in relation to the previously described three input AND logic element AND ₄ . Here, the NAND logic element NAND ₃ cuts off the set input terminal of the flip-flop 3, and the timer 6 is continuous because the output of the wireless paging receiver PR is continuously output for several tens of seconds (about 20 seconds). It is used to precisely set and reset the operation by delaying it beyond the output time limit.

Meanwhile, when another embodiment of the present invention is described, a radio frequency for turning off a load is operated by decoding an alarm signal for informing an emergency, for example, when a plurality of frequency decoders FD ₁ and FD are received. ₂ ), when the reference frequency is set and is matched with the alarm signal input of the emergency, it generates an output of “L” level, which is inverted and output from the NOR logic element NOR ₁ to compare the voltage with a voltage comparator ( It is applied to the inverting input terminal of VC ₁ ). When the alarm signal is continuously received even after the delay time of the delay circuit D passes, the voltage comparator VC ₁ generates an output of “H” level. The output is generated in the “H” state as it is input to the set terminal of 3 ＇), and thus, the drive control logic circuit 4＇ consisting of the 3-input AND logic element is outputted as “L” and is loaded or turned off.

The reset of this other embodiment is only possible with the photo reset described above.

As described above, the remote control circuit of the unmanned lighting apparatus of the present invention can be controlled by radio call codes and radio frequencies by mutual combinations, and various modifications can be made to connect the output stages to the driving units of all lighting loads. It is also found that the present invention is included in the technical configuration sought.

The remote control circuit of the unmanned lighting device as described above has a circuit operated by an alarm signal or a radio call code when an emergency situation occurs, and remote control by radio frequency as a means of turning off the emergency light with the convenience of the unmanned lighting device. It is a very useful invention that can maximize the efficiency.
