The present invention relates to a streetlight point control method and an apparatus thereof. As is well known, two methods are generally applied for lighting and turning off a street lamp.

One is a central control system that emits radio waves from the central control center, and these radio waves reach a receiver installed on one side of the street lamp, and the receiver is turned on or off according to the command data contained in the received radio waves. There is an individual control method that turns on or off when the controller reaches the appropriate time.

According to the individual control method, since radio transmission and reception facilities and professional workers are not necessary for central control, it is mainly applied to streetlight control of street lamps installed in local roads.

This conventional individual control method calculates the altitude angle of the sun based on the latitude and longitude inputted by the microprocessor and the date and time date and time data provided by the built-in clock. When the street lights were turned on and the calculated altitude of the sun increased above a certain angle, it was regarded as sunrise and turned off.

In practice, however, the sunrise and sunset may be delayed or accelerated depending on the location of the installation area and the surrounding conditions of the streetlight installation area. There is a problem.

Therefore, Korean Patent Publication No. 94-2418 (name of invention: Automatic flashing and illuminance control method of street light flasher) has been proposed, and street light point control is controlled in consideration of the difference of sunset and sunrise time according to the region. The technology was introduced to provide convenience to people's life and to reduce the brightness of the street lights by 100% to 60% at a set time of human consumption.

However, since the street lamp is a discharge lamp, not an incandescent lamp, there is a problem in that the illumination is not properly adjusted because the discharge characteristics are nonlinear.

SUMMARY OF THE INVENTION In view of these problems, it is an object of the present invention to turn off a portion of a street lamp at a predetermined time at a predetermined time, so that a light-weighting agent is performed at a time when a vehicle or a pedestrian is small, so that a power saving effect can be obtained.

The object of the present invention can be achieved by having a lightswitch connected to the input port of the CPU and turning it off so that the lights are maintained for a predetermined time. It was.

As can be seen from the above, the present invention is equipped with a ROM for inputting sunrise time and sunset time data corresponding to, for example, one year, and then starts supplying power.

In this way, when the power is input, the CPU determines whether the power switch is on, and since the power switch is on, it initializes the values of the RAM and the register and inputs time-related data.

To this end, the present invention can prepare the function key 1 as shown in the second road, whereby the year, month, day, hour, minute, second data can be input. For example, when the set key and the increase key are pressed at the same time, "1" is displayed on the liquid crystal display 9 and an initial number corresponding to the light is displayed. In this case, when the increase key is pressed, the number displayed on the liquid crystal display 9 increases, and when the decrease key is pressed, the number displayed on the liquid crystal display 9 decreases, so that the corresponding year can be displayed by operating the increase and decrease keys. In this state, when the enter key is pressed, the number displayed on the liquid crystal display 9 is inputted as the year display. Then, the “2” is displayed on the liquid crystal display 9 and the initial number is displayed again. You can use it to display the current month.

In this way, if the enter key is pressed after the month is input, the LCD display 9 displays “3” and the initial number to display the current day. The current date is displayed by operating the increase and decrease keys. You can do it.

In addition, when the date is completed and the LCD display 9 displays “4”, the current time is input in the same process. If the “5” is displayed on the liquid crystal display 9, the minute is entered in the same process. If it is left for 10 seconds or more after pressing, it is in operation mode.

In addition, it is necessary to pull or slow the lighting time or the lighting time off due to the nature of the installation area of the street light. By pressing the set key and the decrease key, “d” is displayed on the liquid crystal display 9 so as to enter the delay time input mode. Press set key to get time "+" mode, press set key to get time delay "-" mode, then press increase and decrease key to get the desired delay time from initial value. The delay time can be set to minutes.

In this process, input the current year, month, day, hour, minute, set the delay time, and then leave it at that time, and the operation mode is automatically entered.

In addition, the CPU receives the date and date related data of the clock 11 from the clock 11 and stores the data in the RAM, and generates a corresponding address based on a table previously stored in the ROM in the RAM. will be.

Next, the generated address is added to the ROM to output sunrise and sunset data corresponding to the corresponding day of the year from the ROM, and the result is stored in the RAM, and then the current hour and minute data is taken from the clock 11 and stored in the RAM. The data stored in the RAM is compared with the sunrise time data and the current time and minute data by the clock 11.

At this time, if these data are the same, it is the sunrise time, and the light out signal is outputted for light-off. As a result, the output state of the drive circuit 7 of the block diagram shown in the third road is reversed, so that the power switching unit 8 is supplied to the lamp. The power will be cut off and therefore turned off.

Subsequently, as time passes, the current time data of the clock 11 becomes the same as the sunset time data stored in the RAM according to the above-described process. Thus, the output state of the driving circuit 7 is changed again to change the power switching unit ( 8) will power the lamp.

Therefore, the street light is turned on to enable night illumination.

However, in the present invention, the lighting time or the extinction time of the street light may be accelerated or delayed in consideration of the terrain or specificity in which the street light is actually installed, and for this purpose, the time and time data of the current clock 11 are stored in the RAM. When the street lamp is installed by checking whether the data is in the same state as the sum of the "+" or "-" delay time inputted in the above-described process and turning on or off by pulling the delayed time, It will be turned on and off according to the characteristics of the region, which will contribute to the convenience of the people's life.

After this operation process, it is checked whether there is a difference of 24 hours between the current time data of the clock 11 and the time data stored in the RAM. It is to perform the above-described process of controlling the power supplied to.

In addition, when 24 hours have elapsed, the data inputted by the clock 11 is received and stored at the same address as the date and date data already input to the RAM, so that the first data is erased and the new date and date data is inputted. After that, the control operation to turn on or off the light is performed in the same process as described above.

In addition, in the present invention, a differential operation for power saving can be selectively performed.

That is, if the light switch 10 is connected to the input port 2 and turned on, it is determined whether the light switch 10 is on before determining whether the difference between the current time of the clock 11 and the time input to the RAM is 24 hours. Check if the current clock (11) data is between 12 pm and 07:00 because it is currently on, and if it is during this time, it is a unequal execution time. If it is not checked whether the difference between the current time of the clock 11 and the time stored in the RAM is 24 hours, a check is performed between the 12 o'clock and 5 o'clock hours. The streetlights controlled by the lamps are turned off between 12 pm and 07:00 when traffic or traffic is rare, helping to save power.

The configuration example for carrying out the present invention is shown as the third degree, and the clock 11 for generating the year, month, day, and hour as a digital code is required in order to implement the present invention. In the input port 2, a function key 1 composed of a set key, an increment key, a decrease key, and an enter key, and a differential switch 10 are connected to the input port 2, and the output port 6 has a drive circuit. (7) and the power switching unit (8) for controlling the supply of electric power necessary for the lighting of the lamp by the output of the driving circuit (7), and the ROM (4) having inputted the sunset time and the sunrise time for each date as digital codes; A CPU having a liquid crystal display 9 for displaying various data inputted by operating the function key 1 and a RAM for storing data necessary for the execution of a program for controlling the elements It consists of (3).

According to the present invention, the CPU 3 moves the current year, month, day, hour, and minute data inputted by the operation of the function key 1 to the RAM, and then transfers the data to the address by a table stored in the ROM 4. The address is added to the address terminal of the ROM 4 and stored in the RAM so that the sunrise and sunset time data of the day are output at the corresponding address, and the CPU 3 performs the sunset and sunrise times as described above. In the same process, a high or low level signal is applied to the driving circuit 7 connected to the output port 6 to operate the power switching unit 8 so that the power supplied to the lamp is interrupted so that the lamp is at sunrise and sunset. It can be turned off or on accordingly.

When the light switch 10 connected to the input port 2 is turned on, the CPU 3 outputs an unlit signal when the current clock 11 time is a pedestrian or a time when the vehicle is rarely operated. It can be maintained to achieve a power saving effect.

In addition, the operation of the driving circuit 7 is controlled by the intermittent timer 12 for 24 hours as shown in the fourth road for the implementation of such a sharpening, for example, from 12 pm to 5 am power switching unit ( The power supply to the lamp by 8) can be cut off so that it can be turned off.

Thus, in the present invention, when turning on the light switch 10 at a desired interval in controlling the street light, the lamp is turned on at a desired interval at a desired time interval, thereby minimizing power consumption and maintaining optimum illuminance. There is a useful effect of being controllable.
