Meanwhile, as illustrated in FIGS. 2 and 3, the GPS signal receiver 100 and the solar power supply unit 200 of the present invention are installed on an upper end of the main body 10, and the central control unit 400 is installed inside the main body 10. ), An output value setting unit 600, a clock detector 300, and a temperature detector 700 are built in, and a lamp driver 500 is installed at one side.

Referring to the operation of the present invention configured as described above in more detail.

First, as shown in FIG. 1, the present invention receives the standard time information from the GPS satellite as the antenna 101, amplifies the signal from the amplifier 102, and then centers the standard time signal received from the GPS satellite receiver 103. Input to the P1 terminal of the control unit (CPU) 400 is automatically synchronized with the internal clock. In addition, the central control unit 116 has a built-in weather and sunrise time program, so the indicator lamps 505 to 508 blink at sunset (night) time by a flashing period value set by the user.

That is, the user operates the DIP switch 601 of the output value setting unit 600 to transmit the set value of the user set to the central control unit 400, the central control unit 400 from the GPS signal receiving unit 100 It receives the standard time data and synchronizes with the internal timer to set the correct time, and outputs the lamp lighting signal at night according to the pre-stored sunrise sunset timetable, and adjusts the blinking cycle according to the input user's setting value. Accordingly, the driving switches 501 to 504 are driven according to the lamp lighting signal output from the central control unit 400 to light the lamps 505 to 508.

At this time, according to the present invention, it is also possible to sequentially control the flashing of the plurality of lamps 505 to 508 by setting for each group unit. That is, since each output terminal (01, 02, 03, 04) of the central control unit 400 is different on / off period of the output, for example, the device set to the output number 01 is installed in a certain number of groups Then, if the device set to the output No. 02 is installed in a certain number of groups in the next position, the same flashing in each group, it is possible to adjust the flashing cycle of the lamp differently between different groups.

In addition, the flashing speed of the lamp is made by the DIP switch 601, for example, blinking at intervals of 0.1 to 0.5 seconds, and the indicator is automatically turned off at sunrise (weekly) time.

In addition, when the clock is poor during the day (eg, rain, snowstorm, fog, etc.), the lamps 505 to 508 are turned on, and the flashing speed is preferably adjusted faster than the reference value.

That is, the clock detector 300 detects the state of the clock by irradiating a pulse-modulated optical signal (infrared ray) in the air and receiving the amount of the reflected optical signal, and transmits the state of the clock to the central controller 400, If it is determined that the clock state is poor by the value detected by the clock detector 300, the controller 400 outputs a lamp lighting signal regardless of day or night.

In addition, the power supply is programmed by the time periodically in the central control computer 400 in order to reduce the power consumption to the minimum used for the clock detector 300, the supply time is initially supplied for 1 to 5 minutes, The power is supplied every 5 to 20 seconds while the power supply is interrupted for 1 to 5 minutes. At this time, when the power is supplied for the initial 1 to 5 minutes and periodically for 5 to 20 seconds, the clock detector 300 only 2 to 10 minutes when the clock is poor. The indicator lamps 505 to 508 blink continuously.

In addition, the temperature detection unit 700 detects the temperature of the atmosphere through the change in the resistance value of the temperature sensor 701, amplifies it in the amplifier 702 and transmits it to the central control unit 400, the central control unit If it is determined that the air temperature has dropped to minus zero (-0 ° C.) by the value detected by the temperature detector 700, the 400 outputs a lamp lighting signal regardless of day or night. At this time, the central control unit 400 preferably controls the operation of the driving switches 501 to 504 so that the flashing cycles of the lamps 505 to 508 blink faster than the reference speed (approximately twice the speed).

On the other hand, looking at the operation of the solar power supply unit 200 of the present invention, the solar collector plate 201 collects sunlight to generate power, the charging control unit 202 under the control of the central control unit 400 By comparing the voltage generated from the solar collector plate 201 and the operating voltage to prevent overcharge and overdischarge, the storage battery 203 stores the power generated from the solar collector plate 201, the constant voltage circuit unit 204 Stabilizes the voltage from the storage battery 203 and supplies it to each part.

The solar cell module generates power during the day to store power in the storage battery 203, but functions as a load that consumes power at night. Therefore, in order to prevent this, the charging control unit 202 has a reverse current prevention function.

In addition, the output value setting unit 600 transmits the lamp blinking speed setting value of the user set by the operation of the DIP switch 601 to the central control unit 400. Here, the blinking speed operation method is as follows. .

Dust, DIP switch 601 is divided into 1,2,3,4, where switch 1 is a group unit setting on / off switch, when the switch on action lamp 505 is flashing sequentially 506 flashes, and then 507 and 508 flash synchronously, and the flashing speed at this time is set by on and off three times and four times.

On the other hand, switch 2 is the temperature setting on / off switch, the action at the time of switch, but switch 1 should be off, it corresponds to the existing setting switch 3 and 4, the standby temperature is below zero at night When descending, the flashing cycle and the flashing speed change according to on / off setting switch 3 and 4, and the flashing speed is doubled according to the value set in 3 and 4.

In addition, the third switch is a flashing speed setting on / off switch, the flashing speed is faster when the switch on, and the flashing speed is slower when the switch is off. Switch 4 is the on / off switch for setting the flashing cycle. When the switch is on, the flashing cycle is faster and when the switch is off, the flashing cycle is slower.
