In general, street lamps are installed for the safety of night riders and crime prevention, and are turned on at night and turned off during the day. Conventionally, people operate the lights in accordance with the sunset / sunrise, but there is a problem of power consumption during unstable careless carelessness due to carelessness. Therefore, a device for automatically controlling the lighting of a street lamp in response to the amount of light in the surrounding area is introduced using a photodetector such as CdS. However, when the light receiving unit of the photodetector is contaminated with dust, a malfunction occurs such that it is turned on during the daytime. There was a problem. Therefore, recently, a microprocessor and a memory have been introduced to store a hundred years of sunrise / sunset time in a memory and to turn on or off a street lamp according to whether the current time matches the sunrise / sunset time. However, such a microprocessor system has a key input unit and a liquid crystal display unit for time correction because it is difficult to precisely turn on or off the timer when an error occurs in the timer. Therefore, the inspector corrects the current time to the correct time through the key input unit and the display unit when an error occurs in the lighting time of the street lamp. Therefore, the automatic lighting device has a key input unit and a display unit for each street light, so that the cost of the device is increased, the volume of the device is increased, and there is a problem that a failure occurs due to moisture penetration, dust or soot due to snow or rain. In addition, because the inspector has to open the control panel of the street lamp when performing time correction and perform the correction agreement, there was a troublesome maintenance and inconvenience.

SUMMARY OF THE INVENTION An object of the present invention is to provide a street light automatic lighting control device and a wireless time transmission device capable of wireless time correction to solve the problems of the prior art.

Hereinafter, with reference to the accompanying drawings will be described in more detail the present invention.

1 is a block diagram of a street lamp automatic lighting control device according to the present invention. The control device is composed of a general power control element for driving the flashing light of the street light 10, the driving unit 12 for switching the driving of supplying AC power to the street light 10 in response to the flashing light control signal; A program for calculating the year and year of the year and the sunrise / sunset time of the year, a memory for storing the system control program and time data, a timer for generating the current time data, and a control data or time correction data. A reception unit 18 which receives a radio signal containing a signal, detects and outputs a data signal from the received signal, and compares the current time of the timer 16 with the calculated sunset / sunrise time data by executing a program stored in the memory. In this case, the timer 16 is supplied to the driving unit 12 by turning on / off the control signal of the street lamp 10 by time correction data inputted through the receiving unit 18. It is provided with a control unit 20 composed of a microprocessor for correcting the current time of the) and is integrally formed with the street light (10). Reference numeral 22 is a power supply.

Referring to FIG. 2, the wireless time transmitter of the present invention has a selection key (S), an ON key, an OFF key, a transmission key (T), an enter key, and a numeric key (1-0) for time input. A key input section 30, a seven-segment liquid crystal display section 32 for displaying year, month day or time, a transmitter 34 for inputting current time data, on and off data and transmitting them as a wireless signal, and the year and year of the year A memory 36 for storing a calculation program, a system control program, and time data; a timer 38 for generating current time data; and a display unit 32 corresponding to a key input through the key input unit 30; And a controller 40 for correcting the current time with the input time data and controlling the transmission of the current time data through the transmitter 34. This wireless time transmitter is a portable equipment used by the inspector and uses either a primary or secondary battery as a power source.

Referring to FIG. 3, the wireless transmission apparatus checks a key input and inputs an S key (300) to perform a time setting mode. In the time setting mode, when the first S-key is pressed, the current year of the system blinks on the display unit (302). If the current year is entered by pressing the numeric keys, the displayed digits stops blinking and are displayed according to the entered numeric keys. 304. Pressing the S key again (306) displays the current day of the system blinks (308) and pressing the numeric key to change the blinking display of the corresponding place at the same time the input of the current month (310). When the S key is pressed again (312), the current system time is blinked and displayed (314). By pressing the numeric keys, the blinking display of the corresponding digit is turned on at the same time as the current time is input (316). Subsequently, when the enter key is pressed (318), the system time is set (320) to the year, month, and day input so far.

When the transmission key is pressed by the key input in step 300 (322), the current time data is checked (323), and the checked current time data is transmitted to the transmitter for two consecutive wireless outputs (326, 328).

When the on key is pressed by a key input in step 322, the on-data is generated (332), and the generated on-data is sent to the transmitter for two consecutive wireless outputs (334, 336).

When the off key is pressed by key input in step 330 (338), off-data is generated (340), and the generated on-data is sent to the transmitter for two consecutive wireless outputs (342, 344).

Referring to Figure 4a, the automatic street light control device checks the time of the timer and calculates the sunset / sunrise time of the date when the date changes, and outputs it in the normal operation mode with the off / on time data stored in the memory. If the current output state is turned on (400), off time data is loaded from the memory to the controller (402), and the current time data is checked (404). Continuous monitoring is performed until the loaded off time data and the current time data are the same (406), and the driving unit is controlled at the same time to turn off the street light (408). Subsequently, on-time data, that is, sunset time data, is loaded from the memory to the controller (410), and the current time data is checked (412). The monitor continuously compares the loaded on-time data with the current time data (414), controls the driving unit at the same time, turns on the street lamp (416), and performs step 402. If it is off in step 400 it performs step 410.

When data is received through the receiver during the normal operation, the interrupt routine of 4b is now performed. The receive operation mode checks data reception (418), detects data from the primary received signal (420) and stores it in memory (422), detects data from the secondary received signal (424) and stores it in memory. In operation 426, the control unit loads the primary data and the secondary data from the memory, and if the two data coincide, it is determined that the data has been properly received without error (428). The street lamp blinks once (432). If the received data in step 430 is time data (434), the current time of the system is corrected with the received time data (436). If the received data is on data (438), the street lamp is turned on for a predetermined time and then turned off (442). In step 438, since the received data is off data, the street lamp is turned off (440). On / off control is the mode used by the inspector to test the street light. The off by off command is to turn off the street light during installation or maintenance. Therefore, the on / off control is released when the on command or time correction command is received again.

As described above, the present invention provides a liquid crystal display and a key input for each control device for the interface between the checker and the control device for time compensation when the system is time-lapsed according to the time when the conventional device is installed in, for example, 100 street lights. Since 100 streetlight controllers can be shared by one key input unit and a liquid crystal display unit, each of which is provided with an unequal input / output device can significantly reduce the cost of the control apparatus.

In addition, since the liquid crystal display and the key input unit are exposed to the outside air, they may be contaminated by dust or soot, or may be easily penetrated by rain or snow, causing frequent failures, thereby increasing maintenance costs. As the input / output device is removed, small size is possible, and the frequency of failure can be greatly reduced by the perfect molding process.

In addition, in the prior art, when the time-calibration of 100 street lights, the inspector has to dismantle the cover of the control panel for each street light, and then press the keyboard by hand to perform time correction manually. If you press the transmission key of the wireless time transmitter at a distance that can be transmitted, for example, within about 50 meters, the time is automatically calibrated, and the maintenance and inspection time becomes very short. You can check.
