Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device capable of predicting weather information.

Generally, when planning a sports day or picnic, the most important thing to consider is the weather on the day. It is often possible to predict the weather a day in advance by looking at the sky, but
It is extremely difficult to make quick predictions one week to two months in advance, and there is no way to do so.

The present invention has been made in view of the above-mentioned drawbacks, and is particularly capable of storing past weather information in memory in association with date information (for example, daily weather information for the past several years in various parts of Japan). Ok,
By specifying a date (for example, using a key), this device provides a device that can output past weather information for that day.It can predict the weather on the day of a sports day, picnic, etc., and easily determine the planned date. The purpose is to be able to do something.

Hereinafter, an example in which the device of the present invention is implemented in a desktop calculator (hereinafter referred to as a weather information calculator) will be described in detail.

Figure 1 shows an external view of the above calculator, and in the figure, 1
is the main unit, 2 is a key unit, and the keys include, for example, numeric keys from 0 to 9, a decimal point key, arithmetic instruction keys, key 2a for inputting the region, key 2b for inputting the month, and key 2b for inputting the day. key for 2
c, key 2d for inputting weather, clock key 2
It consists of e, etc. Reference numeral 3 denotes a display, which is composed of, for example, a dot matrix liquid crystal display.

Specifically, the past of major locations such as Tokyo, Osaka, and Fukuoka.
Store daily weather information for 10 years in advance in memory.

Weather information is classified into four types: clear, cloudy, rainy, and snowy, and is displayed with each symbol mark (Figure 3).
In addition, the main areas are divided into 10 areas as shown in Figure 4, and data is stored for each area. By specifying the month, day, and region using the keys, weather information as shown in FIG. 2 is displayed.

FIG. 2 shows an example of the display on the display 3, where 30 is clear,
31 represents rain, 32 represents cloudy weather, and 33 represents snow. The display for displaying these marks is composed of a dot matrix liquid crystal display, and each mark is represented by a dot. 34 is a number representing the year, and is displayed fixedly in this embodiment.

This device normally operates as a clock or calculator, but if you want to know the weather, use the following key operations.

First, specify the region. This is done by entering key locations using numerical codes as shown in Figure 4 (see Figure 1). For example, in the case of Tokyo, after inputting ``3'' on the numeric keys, the ``area'' key 2a is pressed. Here, the code list of the main locations can be provided inside the notebook-type case that houses the device. Next, specify the month and day. For example, if it is March 4th, press the number key "3",
"Month" key 2b, number key "4", "day" key 2c
Enter the keys in this order. Then "weather" key 2d
If you press , a display as shown in Figure 2 will appear.

That is, the weather in Tokyo for the past 10 years can be predicted based on the display.

FIG. 5 is a system block diagram of the main parts of the weather information calculator according to the present invention.

In the figure, 2 represents a group of input keys, 2a is a "region" key, 2b is a "month" key, 2c is a "day" key, 2d is a "weather" key, 2e is a "clock" key,
25 is a numeric key.

When the area code of a major place is input using the numerical keys based on FIG. Next, if you press the "Region" key 2a, the key input buffer 5
The area code stored in the buffer input control unit 6
The data is transferred to area code buffer 7 via . Similarly, numerical values corresponding to the month are input via the buffer input control section 8 to a buffer 9 for temporarily storing month data, and data relating to the day are input via the control section 10 to the day buffer 11. If you then press the "weather" key 2d, the calculation unit 12 that calculates the number of days will tell you what day of the year the input date (month and day) corresponds to, that is, how many days after January 1st. The correspondence is calculated. In addition, at this time, February
It is calculated as if there were 29 days and can be calculated using known methods. Based on this calculated number of days (output of calculation unit 12) and area code (output of buffer 7),
The start address is determined by the address determining section 13. Once the starting address is determined,
Weather memory information in which daily weather for each major location is stored for 10 years is read out from the memory unit 14. 15 is an address register, 16 is an address decoder, and 17 is an output control section. Here, the contents of the memory unit 14 are expanded and shown in FIG. 6 for easy understanding, so a description will be added. The memory contents are roughly divided into 10 major locations as shown in Figure 4, and the daily weather for each major location is stored for 10 years. Each weather is stored in 2 bits (4 ways shown in Figure 3). 70, 71, 72, . . . shown in the figure indicate the order in which the weather of the year is stored (it does not indicate the stored contents). The data for each major location is continuous in terms of addresses as shown in the figure. According to this format, if you know the area code in Figure 5 and the number of days from January 1st (7 and 7 of 12 in Figure 5), you can determine the start address to read. Can be done. The content read from the memory unit 14 is 20 bits from the start address, and this content is transferred to the output buffer 18. Also, the read control unit 19
reads out the contents of the output buffer 18 2 bits at a time in year order, converts it into a display code in the character generator 20, and inputs it to the display buffer 21. Further, 22 is a register for storing the date and time, M is the month, D is today's information,
Tomorrow's date information is input into buffers 9 and 11 by the date information input control section 23. That is, unless a date is specified using key 2, tomorrow's weather information will be displayed. Further, the numerical value input into the area code buffer 7 continues to be stored until it is specified again using the key. Therefore, unless a region code is specifically specified using a key, the previously specified region will be automatically selected. When clock information is to be displayed, by pressing the clock key 2e, the contents of the register 22 are sequentially read out by the readout control section 24 and displayed on the display section 3. In addition, 25,2
6 is a clock generator and frequency divider for forming a clock circuit.

In the embodiment, the weather of the day for each year is displayed using a symbol mark, but it is also possible to calculate the probability of occurrence of each weather code from the information transferred to the output buffer 18 and display this. be.
Further, in the embodiment, weather information is stored in the memory in advance, but it is also possible to use this information by writing it into the writable memory using a key or an external input device.

As described above, according to the present invention, by inputting the date and region, the past weather information for that day in the specified region is displayed and output for each year, which is often useful for predicting the weather. , which increases the certainty of predictions.
