Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a time switch with a solar function that performs control according to sunrise and sunset times throughout the year.

For example, a time switch with a solar function turns on street lights at sunset and turns them off at sunrise.

or turn on advertising lights at sunset, or turn on advertising lights at 12 midnight.
This is used when turning off the power at times. sunrise,
Sunset times vary considerably throughout the year, as shown in Figure 1. Also, the sunrise and sunset times in various parts of Japan are different. In order to perform control according to the sunrise and sunset times, which change depending on the month, day, and location,
Conventional time switches with solar functions are equipped with a special cam mechanism, and the special cam mechanism has a different shape depending on the region where Japan is divided into six latitudinal regions. Therefore, even if the longitudes are different, the control is the same, and a certain amount of error occurs in the control time between the easternmost region and the westernmost region. Also,
When the power is initially turned on, if you do not check the sunrise and sunset times of the day in a newspaper and make solar settings, there is a risk that the control time will be incorrect throughout the year.

An object of the present invention is to provide a time switch with a solar function that can solve the above-mentioned problems, reduce errors due to differences in longitude, and facilitate solar settings.

In order to achieve this object, the present invention provides a setting input means for inputting at least the year, month, and day of the setting day, the latitude and longitude of the installation location, and the sunrise and sunset times of IJ 4rJ that input the latitude and longitude. and a control means for controlling the output in accordance with the sunrise and sunset times. It is also characterized in that it is not necessary to input the sunrise and sunset times of the day at the time of setting.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

Figures t52 to t5 are diagrams showing an embodiment of the present invention that uses both solar control and scheduled control. As shown in Figure 2, on the front of the time switch l with solar function are a key switch 2, a set switch 3 for switching between setting mode and automatic operation mode.Normally, the current time is displayed, and when setting, the year (year (lower two digits), data display section 4 that displays the month, day, control time, and circuit number; day of the week display section 5 that normally displays the day of the week; and the day of the week that is being set during setting; and the circuit that is normally on. An output status display section 6 is provided which displays the circuit being set and displays the circuit being set during setting. In this embodiment, only the No. 5 circuit performs solar control, and the No. 1 to 4 circuits perform regular control.

FIG. 3 shows a block diagram of an embodiment of the present invention, FIG. 4 shows a flowchart of its basic operation, and FIG. 5 shows a flowchart of solar control processing.

In FIG. 3, the operating section 7 also includes a key switch 2 and a set switch 3. First, the setting of scheduled control will be explained. Switch the set switch 3 to the setting mode, and operate the key switch 2 to set the year, month, day, and day of the week.
When the current time is input to the calendar/clock section 8, the calendar/clock section 8 starts measuring time. Further, when control data related to scheduled control, that is, day of the week, circuit number, control time (minimum set interval of 1 minute), and control details (on, off) are input, these control data are stored in the first memory 9. Details of these settings are as follows.

Enter the C control time (00:00-23:59) in 4 digits.

d Set the control details (ON, OFF) using the ON key switch or OFF key switch (7).

e Press the write key switch to complete the control data setting.

When setting solar control, press set switch 3.
Switch to the setting mode, enter the east longitude and north latitude data of the installation location by operating key switch 2, and save the data to the second memory l.
Let O memorize it. Details of latitude and longitude settings are as follows.

(6) Longitude setting a.Press the East/North key switch 1@ or an odd number of times.

b Enter the east longitude of the installation location in 3 digits using the numeric key switch.

Press the C write key switch to complete the longitude setting.

(7) Latitude setting a.Press the East/North key switch twice or an even number of times.

b Enter the northern latitude of the installation location in two digits using the numeric key switch.

Press the C write key switch to complete latitude setting.

As the east longitude and north latitude data are stored in the second memory 10, solar control processing by the arithmetic unit 11 is performed as shown in FIG. The calculation unit 11 calculates the daily sunrise and sunset times T at the installation location from the formula T=To+MthN・n.
Do X. However, T is the daily sunrise and sunset time on the 5th of the former Tokyo Observatory (referring to the former site of the center of the Great Calf Observatory), data recorded in "Science Chronology J" compiled by the Tokyo Astronomical Observatory, and M is the eastern longitude as an argument. is the auxiliary number that takes the northern latitude as an argument, and N is the auxiliary number that takes the northern latitude as an argument; Data listed, n is 1/2 of the time from sunrise to sunrise
This is an auxiliary number whose argument is the time difference p, which is also data related to the sun in Table 3. + in front of N is selected at sunset, and - is selected at sunrise.

The sunrise and sunset times at the former Tokyo Observatory are stored in advance in the third memory 12, and similarly, the auxiliary numbers M, N,
n is stored in advance in the fourth to sixth memories 13 to 15.

The calculation unit 11 reads the east longitude and north latitude data from the second memory 10, reads the auxiliary number M from the fourth memory 13 using the east longitude as an argument, reads the auxiliary number N from the fifth memory 14 using the north latitude as an argument, and calculates the calendar. The month and day of the current day are read from the clock section 8, and the sunrise and sunset times To of the former Tokyo Observatory for the month and day read from the third memory 12 are searched. p=
1 Calculate the time difference p from the formula (sunrise time - sunset time) 1/2, and use this time difference p as an argument to store the time difference p in the sixth memory 15.
The auxiliary number n is read from 0 sunrise and sunset times T. By substituting the auxiliary a M + N + n into the above equation, the sunrise and sunset times T at the installation position are calculated. This time T is stored in the first memory 9 as the solar 8 control time. The solar control process described above is performed not only when the power is initially turned on, but also when the day changes, for example, at midnight every day.

Regarding circuit No. 5, if you want to set either ON or OFF to regular control instead of complete solar control, specify circuit No. 5 in conjunction with the solar control settings and set it to Control data settings can be performed in the same way as for control.

If you want to move the solar control time within the range of ±60 minutes, switch the set switch 3 to setting mode, and if you want to advance the control time, press the +/- key switch an odd number of times.
Conversely, if you want to slow it down, press it an even number of times. Then, enter the time to be moved using the numeric key switches and press the write key switch.

When all setting operations are completed, switch the set switch 3 to automatic operation mode. In automatic driving mode,
The comparison unit 16 compares the current time with the regular control time or solar control time stored in the first memory 9, and when they match, relays the output control signal from the output control unit 17 (
(not shown).

According to this embodiment, the calculation unit 11 calculates the sunrise and sunset times T according to the latitude and longitude, so that errors caused by differences in longitude can be reduced. In addition, when setting up the solar, you only need to enter the latitude and longitude of the installation location, and there is no need to set the sunrise and sunset times on the day of setting, unlike in the past, making solar settings easier and preventing mistakes. Settings can be removed. Furthermore, the same product can be used in any region of Japan.

In the illustrated embodiment, the key switch 2 corresponds to the setting input means of the present invention, the first memory 9 and the calculation section 11 correspond to the calculation storage means, and the comparison section 16 and the output control section 17 correspond to the control means.

In the illustrated embodiment, the calculation unit 11 calculates the sunrise and sunset times T for each day at the set position, but the whole country of Japan is divided into several 10 locations, for example, about 49 locations, and each region is divided into For example, the sunrise and sunset times for every 10 days may be directly stored in the memory, and the sunrise and sunset times for each day may be determined based on the month and day data from the calendar/clock section 8.

As explained above, according to the present invention, there is provided a setting input means for inputting at least the date of setting light 1, the latitude and longitude of the installation position, and the setting input means for inputting at least the year, month, day, latitude and longitude of the installation position of "setting light 1", and the setting input means for inputting at least the latitude and longitude of the setting light 1, It is equipped with an arithmetic storage means for calculating and storing the time, and a control means for controlling the output in accordance with the sunrise and sunset times of the day. In addition, since it is not necessary to input the sunrise and sunset times of the day when making settings, errors due to differences in longitude can be reduced and solar settings can be easily performed.
