Abstract

PURPOSE:To make an indirect and efficient indication with simple configuration, by lighting indicating elements on indication blocks corresponding to the digit of respective places. CONSTITUTION:An indication block 1 consists, for example, of nine indicating elements 1a-1i, which are arranged in a matrix with three columns and three lines and represent a digit of 1-9 respectively. A plurality of indication blocks 1 are prepared according to the number of figures for the indication of watt- hour value. Here, the indication blocks 2, 3, 4 and 5 represent the first, second, third and fourth digits, and the blocks 6 and 7 represent the first and second decimal places. Thus, by forming indication blocks with a plurality of indicating elements such as LED devices which emit light according to the digit of respective places, a watt-hour value can be indirectly indicated.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in the display method of an electronic integrated watthour meter.

(Prior Art) Conventionally, electronic integrated power meters have been equipped with a mechanical counter device that uses a stepping motor to rotate a counter mechanism to count and display the integrated power amount. It is known that the image is displayed electronically using a seven-segment liquid crystal display.

(Problem to be Solved by the Invention) By the way, all of the above-mentioned conventional electronic power meters have the advantage of being able to directly read the integrated power amount, but they do not display the integrated power amount separately for each time period. If the number of display units is to be displayed, it is necessary to provide a number of display units corresponding to the number of divisions in the time zone, and there is a limit to reducing the area occupied by the display unit from the perspective of direct reading of the numbers. Although the area occupied by each time zone is small, there is a problem in that the larger the number of time zones, the larger the area occupied by the display section as a whole.

Further, as the number of time zone divisions increases, the structure becomes more complicated, the materials used increase, the number of wiring increases, and the cost increases.

(Object of the Invention) The present invention has been made in consideration of the above circumstances, and its purpose is to simplify the configuration, reduce the occupied area, and display the integrated power amount by time zone. An object of the present invention is to provide a display method for an electronic integrated watthour meter that can cope with the above problems.

(Means for Solving the Problems) The display method of the electronic integrated watthour meter according to the present invention is characterized by:
A display block is constructed by arranging a plurality of display elements such as liquid crystal elements, LED elements, ECD elements, etc., and each display element of this display block is lit in correspondence with each digit of the integrated power amount, and each display element is The integrated power amount is indirectly displayed depending on the lighting position of the element.

(Operation) In the case of the invention of this method, the number corresponding to the display element of the display block is determined based on the lighting position of the display element,
This means that the integrated power amount can be read indirectly.

(Example) A display method of an integrated power consumption meter according to the present invention will be described below with reference to the drawings.

FIG. 1 is an enlarged view of a display section of a display method of an integrated power consumption meter according to the present invention, and in FIG. 1, ■ is a display block. The display block 1 here is composed of nine display elements 18 to 11, and the display elements 18 to 1j are arranged in a matrix of three vertically and three horizontally. Here, the display elements 18-11 are made to correspond to each number "1-9", respectively, as shown in the figure.

The display blocks 1 are provided in the number corresponding to each display digit of the integrated electric energy, and in FIG. 2, 2 is a display block for the "1" digit, and 3 is a display block for the "10" digit. , 4 is rloOJ digit display block, 5 is rl
Shows the display block for the digits of oooJ, and 6 is the decimal point.
7 indicates a display block with a digit of "1", and 7 indicates a display block with a digit of "10" below the decimal point. This row of display blocks arranged horizontally corresponds to one integrated power amount display section, and the number of rows of display blocks is equal to the number of time periods to be displayed. For example, 5
When displaying the integrated power amount for each type of time, the number of display block columns is five.

When displaying the integrated power amount, the display element in the display block corresponding to each digit is lit up, and the number "0" is changed to the number "1". The corresponding display element 1a is made to correspond to the display element 11 corresponding to the number "9". For example, when the integrated electric energy is r1357.90KwhJ, as shown in FIG. It lights up the element 1g, the display element 1j of the display block 6, and the display elements 1a and 11 of the display block 7, and reading the integrated electric energy is indirectly determined from the lighting position of the display element for each display block. This is done by doing so.

FIG. 4 shows the second display method of the integrating watthour meter according to the present invention.
This is a diagram for explaining an embodiment, and the display method of this second embodiment is a combination of so-called binary codes.
It represents the number ``9'', and the display block is composed of digits below the decimal point and above the decimal point, and the display elements of the display block 8 above the decimal point are arranged in a matrix of ``4'' horizontally and ``5'' vertically, and the display is displayed vertically. The column of elements corresponds to the "1" digit to the rlooOJ digit of the integrated electric energy, and the horizontal display element column corresponds to the binary code "2°" to "23", and the decimal point The display elements of the display block 9 below are arranged in a matrix of "2" horizontally and "5" vertically, and the columns of vertical display elements correspond to each digit of the integrated power consumption meter below the decimal point, and the columns of horizontal display elements from "2°" to "23" in binary code
It is designed to correspond to the following. In FIG. 4, symbols 8a to 8t and 9a to 9j indicate respective display elements. In the case of the display method of this embodiment, only the number "0" is specially displayed in a row of horizontal display elements.

With this display method, for example, the integrated power amount r135
7.90'', the display element 8e for the rloooJ digit, the display elements 8f, 8j for the rloOJ digit,
Display elements 8g and 8o for digits of "10", display elements 8h and 81.8p for digits of "1", display element 9 for digits of decimal point "1"
c, 91, and the display element 9b of the decimal point "10" is lit.

According to the display method according to this embodiment, the number of display elements can be reduced compared to the display method shown in FIG.

In the second embodiment, if the display color is made different for each row of horizontal display elements corresponding to the binary code, reading can be facilitated even at night.

(Effects of the Invention) As explained above, the display method of an electronic watt-hour meter according to the present invention includes arranging a plurality of display elements such as liquid crystal elements, LED elements, and ECD elements to form a display block. This method involves lighting up the display elements of the display block corresponding to each digit of the cumulative power amount, and indirectly displaying the cumulative power amount based on the lighting position of the display element. Compared to conventional display methods, the display space can be made smaller, and the present invention has the advantage of being compatible with electronic integrated power meters that display integrated power amounts by time zone.

Further, since the numbers can be determined simply by changing the position where the lights are turned on, the configuration is simpler than that of a device related to the display method of a conventional direct-reading electronic watt-hour meter.
