Description

Lamp remote controller using PLL {Lamp remote controller using PLL}

The present invention relates to a luminaire remote control device using a PLL (Phase locked loop, hereinafter referred to as a PLL), and more particularly, a luminaire installed in a large area, for example, by controlling a street lamp remotely from a central control station. It relates to a luminaire control device that turns off and on.

Here, the PLL is an electronic circuit composed of a phase detector, a low pass filter, and a voltage controlled oscillator. The PLL is a PM demodulation network having excellent linearity between the input signal frequency of the FM operation and the PLL output voltage, or a frequency-shift (FSK). Keying) is a circuit that is applied to two data transmissions in digital data transmission used for the operation, or for optical methods such as AM frequency demodulation or AM detector and tracking filter.

In general, a conventional luminaire on-off control method uses a control device using a power switch, a control device using an optical sensor, a control device using a time switch, and an on-off operation state using a control device by radio wave reception. To control.

However, in the case of the control device using the power switch, the manpower and time wasted to operate the power switch is severe, it is difficult to maintain the consistency of the lighting device, the point and the lighting time, and also the control device using the optical sensor In this case, the operation of the optical sensor is susceptible to the influence of the environmental factors, and thus malfunctions and incomplete operations, for example, when dust gets on the surface of the optical sensor, the amount of light reaching the optical sensor is small and is recognized at night even during the day. The luminaire may turn on, causing a waste of power.

In addition, in the case of the control device using the time switch, since the operation is performed only at the set time, the lighting and lighting are uniformly made without considering the sunrise and sunset time that changes every time according to the season. In addition, even when weather conditions, for example, when the weather is not good due to rain or fog, it is difficult to achieve the original purpose of the luminaire because it is not turned on in reality, and finally, In the case of the control device by the radio wave reception, when the radio wave is transmitted in order to turn on and off the experiment in the field, the luminaire in the adjacent distance receives the control signal and lights up to generate a power waste, and separately to transmit the radio wave. Of the radio station because it is necessary to construct a radio station And maintenance is constantly required, and luminaire control devices that are out of the radio wave coverage range cannot fully utilize their functions unless additional radio stations are constructed, and the frequency used according to each region and area of use. Is different, and the number of radio transmission stations is low, so the radio reception rate is low as 80 ~ 90%, so it is difficult to control the operation precisely by the central control. If the current street lights are turned on and off, but the current time supplied from the clock circuit and the preset reservation time are malfunctioning, there is a big difficulty in management because the function cannot be checked.

Accordingly, an object of the present invention is to solve the problems of the conventional power supply control apparatus as described above, and simultaneously transmit a signal using an existing call service and use the PLL to transmit the received signal. Since it automatically recognizes the frequency of the signal and sets the data corresponding to the area, it turns on and off, so there is no need for a separate wireless transmission station, and it is necessary to set and design the frequency range of the lighting equipment according to the area. If the luminaire malfunctions or fails to operate due to a lightning strike occurring during the use of the luminaire control device, the PLL is used to automatically recognize the area where the luminaire control device is installed and reset the data. In addition to reducing waste of time and time, lighting equipment at the time of occurrence of environmental factors such as weather conditions Operation of the control unit is to enable the control to the radio terminal, to provide a lighting equipment remote control device using the PLL to increase the use, and energy efficiency.
