As can be seen in the present invention, when the personal computer is turned on and booted, the present invention displays a radio button corresponding to an execution command on the monitor screen to start a program as shown in FIG. When the radio button is clicked on, the operation as shown in Fig. 3 is performed. Accordingly, the present invention first provides a data value input window for overall operation to receive various data necessary for operation. First, the present invention receives the use of the radio, the use of the light meter, the use of the GPS in the data value input window, and then, the time interval for receiving the light meter data, the time interval for counting the average data value, and the GPS The reception data application period and the setting data transmission period of the time data by reception are set, and the street light unit ID is input and completed.

In this state, when the administrator clicks the radio button corresponding to the completion of input in the monitor screen window, the CPU takes the data of the region from the memory where the sunrise and sunset time data of each region is stored in the main memory. In this state, the CPU activates the corresponding communication port according to whether the radio is used, the illuminometer, and the GPS in the above-described process, and adjusts the correction value of the time for turning off and turning on before and after sunrise and sunset. An input window for input is displayed on the monitor screen display to prompt the administrator to enter this value. In this manner, after the administrator completes input of various data, the CPU receives data of the illuminometer through the communication port every one second that is set in the timer and stores the average brightness of the ambient light by the illuminometer in the memory as a digital value. This value is calculated as an average value and stored in the database every minute. Then, GPS data is received through the communication port to calculate the time value separately from the received data, and it is determined whether the application period of the time data has been applied. When the application period is reached, the system time is synchronized immediately.When the setting data transmission period is reached, the radio data is transmitted through the communication port, but a plurality of flashing data are sequentially transmitted by the ID of the street light in the predetermined format. Will be done.

By repeating this process, if the average value of the illuminometer is very low, and the situation is necessary to adjust the point and the extinction time, the CPU may turn on or turn off the light for 10 minutes according to the grade corresponding to the total value of the illuminometer. The lighting time and the lighting time are set to the time value of pulling or slowing down and are transmitted to the plurality of street light receivers through the wireless transmitter.

In addition, in the present invention, in the application of GPS reception data, by synchronizing with the system time at appropriate time intervals, the operation time criteria of a plurality of street light receivers are corrected, so that accurate dot and light operation can be performed automatically. do.

In this invention, since data stored in the database is managed and input on a personal computer, it is most practical to use Excel, and thus, various data inputted and modified in this series of processes are converted to Excel. This is shown in FIG.

In addition, Figure 5 shows an example of a street lamp receiver for receiving a radio wave transmitted in the present invention. As can be seen from this, the present invention is a mixer with an output of an oscillating circuit which is operated by a receiving antenna, a band pass filter for filtering reception frequencies, a high frequency amplifying circuit, and an output of a PLL controlled by a microcontrol unit. A filter for passing a signal converted to an intermediate frequency through the signal, an intermediate frequency amplifier circuit for amplifying the intermediate frequency, a modem supplied with an audible frequency, and a serial for serially outputting digital data output from the modem. It consists of a port, relays and street lamps connected to the serial port, a keypad for setting and controlling the operation of the micro control unit, a display panel for displaying the operation status, and a memory for storing various data.

This streetlight receiver will receive a four-byte data format of the type listed below.
