3d, 3e, 3f are graduated numerical indicators for displaying the scale value of the measurement object, 4 is a unit indicator, and A, KA, MA are used as units in the case of the AC ammeter used for the power distribution board, In order to display by switching these three units, A
Indicates the display units 4a, KA displays the display units 4b, 4d, 4a, and MA displays the display units 4d, 4c, 4a to perform unit display.

Next, FIG. 2 shows a display control device for controlling the display of each display of the display device 1.

In FIG. 2, reference numeral 11 denotes a circuit to be measured, and in the case of an AC ammeter, a current transformer (hereinafter referred to as CT) 12 for a meter, which is proportional to the current flowing in the circuit 11 to be measured, for example, AC0 to AC0. A measurement signal of 5 A is obtained. Thirteen

Reference numeral 4 is an A / D converter for A / D converting the DC voltage signal into a digital signal such as a binary code, and 15 is an A / D converter.
This is a bar graph display control unit for converting the output of the / D conversion unit 14 into a signal for driving and controlling the bar graph display unit 2 and controlling the bar graph display unit 2 for displaying the measured value.

Reference numeral 16 is a maximum scale value setting section for setting a maximum scale value which is a primary side value of CT12, and the primary side value of CT12 of the circuit 11 to be measured, for example, CT ratio is 100.
In case of / 5, AC100A is set. When the measurement target is the AC voltage of the circuit 11, a value on the primary side of the meter transformer VT (not shown), for example, AC6600V is set when the VT ratio is 6600/110.

Reference numeral 17 is a scale number calculation unit, which calculates the display values of the scale number displays 3a to 3f based on the primary side value of the CT 12 set by the maximum scale value setting unit 16 by the following formula.

Therefore, in this case, N is 0 to 5. Therefore, for example, if the transformation ratio of CT12 is 100/5, the display values of the respective scale number indicators 3a to 3f are the scale number indicator 3a =
0, scale number display 3b = 20, scale number display 3c =
40, scale number display 3d = 60, scale number display 3e
= 80, the scale number display device 3f = 100, and the scale number display control unit 18 converts the signals into signals for driving the scale number display devices 3a to 3f to display and control the scale numbers.

Reference numeral 19 denotes a unit calculation unit, which calculates a unit based on the set value of the maximum scale value setting unit 16. That is, in the case of an AC ammeter, when the set value is <1000, when A 1000 ≤ set value <1,000,000, and when KA 1,000,000 ≤ set value MA
Then, the unit display control section 20 displays the corresponding display unit among the unit display units 4a, 4b, 4c and 4d so as to obtain this display.

In this case, the above-mentioned scale numeral display 3a.
Also in 3f, it is necessary to display the scale numbers with the decimal point added according to this unit. For example, CT ratio is 10
In the case of 00/5, the unit indicator 4 displays KA,
In this case, the display values of the scale number indicators 3a to 3f are as follows: scale number indicator 3a = 0, scale number indicator 3b = 0.2,
Scale number display 3c = 0.4, scale number display 3d = 0.
6, scale number display 3e = 0.8, scale number display 3f
The display including the decimal point is controlled by the scale numeral display control unit 18 so that = 1.0.

Therefore, according to the measurement value display device having the above-mentioned configuration, the scale number and the unit display corresponding to the bar graph display are C
It can be set by the maximum scale value setting unit 16 that sets the maximum scale value of the primary side current value or voltage value of T12, and it is not necessary to individually prepare the basic pattern of the liquid crystal in accordance with the actual scale, and the cost is reduced. It has an effect that can be realized at a low cost. In addition, the current value on the primary side of CT12 or V
By switching the setting of the maximum scale value of the primary side voltage value of T, the scale number and unit display are automatically switched by calculation, so even if it is diverted to another circuit with a different CT ratio, it can be handled by simply changing the setting. Therefore, unlike the conventional mechanical instrument, it is not necessary to replace the scale plate and the dial plate by reprinting, and thus the versatile effect can be obtained.

Similarly, the appearance of the AC voltmeter is as shown in FIG. The unit display is as follows. When set value <1000 V 1000 ≦ set value <1,000,000 KV 1,000,000 ≦ set value MV
Then, the unit display control unit 20 displays the corresponding display unit among the unit display units 4e, 4b, 4c and 4d so as to obtain this display. Although not shown, in the case of an AC voltmeter, CT12 in FIG. 2 becomes VT, and the conversion unit 13
Has a function of inputting a value on the secondary side of the VT, that is, AC110V, and outputting a DC voltage signal of DC0 to 5V proportional to this.

Example 2. Next, a second embodiment of the present invention will be described with reference to FIG. In FIG. 4 in which the same parts as those in FIG.
The value on the secondary side of 2, that is, the rated value setting unit that sets the rated value in order to obtain the output from the conversion unit 13 according to the rated value, and corresponds to this when the rated product of the instrument transformer is changed. The conversion setting value is given to the conversion unit 13 in order to convert the display instruction value.

That is, in the case of an alternating current ammeter, the secondary side of CT12 has rated products of AC0 to 1A in addition to AC0 to 5A.
When connected to the 1A CT12, there is a problem that the indicated value is displayed five times larger. Therefore, the rated value setting unit 21 for setting the secondary value of the CT 12 for setting the secondary value of the CT 12 is provided, and the conversion function of the conversion unit 13 is set to, for example, 0 to 1 A according to this setting. If yes, the measurement input AC
For 0 to 1 A, DC 0 to 5 V proportional to this is converted. As a result, any CT12 having a different rated product can be used.

Example 3. A third embodiment of the present invention will be described with reference to FIG. FIG. 5 is a diagram showing a configuration of a third embodiment of the present invention, in which the display device 1 to the unit display 4,

Then, the scaling calculator 22 and the digital display controller 2
It consists of three.

The scaling calculation is as follows. For example, the value on the secondary side of CT12 is AC5A, and this value is converted by the conversion unit 13 into a DC voltage signal DC0 to 5V.
To the A / D conversion unit 14
The digital signal is converted into a digital signal by, but if the digital signal is displayed on the digital display unit 24 as it is, the current value flowing through the circuit 11 to be measured is not displayed.
It is necessary to convert it to a value on the primary side of 12. A scaling operation is an operation for converting the digital signal into a value on the primary side of CT12. Here, the following calculation is performed.

Display data of digital display section 24 = {(set value of maximum scale value setting section 16) × (conversion data of DC voltage signal of A / D conversion section 14)} / (DC5V of A / D conversion section 14) Conversion data)

The calculation result is displayed on the digital display section 24, and the value of the current flowing through the circuit 11 to be measured can be directly read. If a decimal point occurs in the above calculation result, the corresponding decimal point is displayed. Therefore, with the above configuration, the value of the current flowing through the circuit 11 to be measured can be roughly grasped on the display of the bar graph display 2, and further the specific numerical value can be read on the display of the digital display section 24.

Here, in the first embodiment, the unit arithmetic operation of the unit arithmetic unit 19 is such that when the set value is <1000, A 1000 ≦ the set value <1,000,000, and when KA 1,000,000 ≦ the set value, MA.
Unit display 4

The scale division calculation unit 25 performs scale division calculation based on the primary side value of the CT 12 of the circuit 11 to be measured, which is set by the maximum scale value setting unit 16, and is arranged around the bar graph display 2. Scale number display 3a-3g, parent scale 29
The lighting states of the a to 29l and the sub scales 30a to 30N are determined. In this calculation, the scale division data corresponding to the primary side value of CT12 is searched from the scale division table 26, and the division of the parent scales 29a to 29l is instructed to the parent scale display control unit 27 based on the searched scale division data. The parent scale display control unit 27 turns on or off the corresponding parent scales 29a to 29l. Similarly, the division of the child scales 30a to 30N is instructed to the child scale display control unit 28 based on the scale division data, and the child scale display control unit 28 makes the corresponding child scale 3.
0a to 30N are turned on or off.

The contents of the scale division table 26 will be described with reference to FIGS. 9, 10, 11 and 12. 9, 10 and 11 are diagrams showing a list of graduation display patterns of the AC ammeter corresponding to the value of the primary side rated current of the CT 12. FIG. 12 is a diagram showing a list of scale display patterns of the AC voltmeter corresponding to the value of the primary side rated voltage of VT.

Regarding the primary side rated current value of CT12, J
It is defined in IS / C1731, "Transformers for Instruments (for Standard and General Instruments)", and the scale display patterns of FIGS. 9 to 11 are the main corresponding ones.

The primary side rated voltage value of VT is also defined in JIS C1731, and the scale display pattern of FIG. 12 is the main one corresponding to this.

9 to 11 show that the scale display pattern 31 and the unit symbol 32 of the AC ammeter are changed depending on the value of the primary side rated current of the CT 12. For example, as shown in FIG. 10, the value of the primary side rated current of CT12 is 100.0.
In case of A, the scale number of the scale display pattern 31 is 0, 2
0, 40, 60, 80, 100, and the scale is divided into five. In addition, the parent scales are arranged at the places marked with the above scale numbers respectively, and the child scales are between the scale numbers 0 and 20, between the scale numbers 20 and 40, between the scale numbers 40 and 60, and between the scale numbers 60. Between 80, between the scale numbers 80 and 100, ie between the main graduations, exactly half are arranged in a split manner.

Next, for example, as shown in FIG.
When the value of the primary side rated current of 12 is 300 A, the scale number of the scale display pattern 31 is 0, 100, 200, 300.
And the scale is divided into three. In addition, the parent scales are arranged at the positions marked with the above scale numbers respectively, and the child scales are divided into 5 between the scale numbers 0 and 100, and the scale numbers 100 and 20.
It is arranged so that 0 is divided into 5 parts and scale numbers 200 and 300 are divided into 5 parts.

00 and 200 are divided into two, scale numbers 200 and 300 are divided into two, and scale numbers 300 and 400 are divided into two.

From a similar view, the method of dividing a large scale can be classified into three types, that is, three, four and five. Then, the parent scale and the scale number are arranged at the position of this large division. For the secondary scale, depending on the value of the primary side rated current of CT12, for example, 300A and 600A are the same 3
Although it is a division, the arrangement of child scales is different.

When these are arranged, as shown in FIGS. 21, 22 and 23, there are six types of arrangement of the parent scale and the child scale. That is, (1) parent scale 5 divisions, child scale 10 divisions, (2) parent scale 4 divisions, child scale 8 divisions, (3) parent scale 3 divisions, child scale 9 divisions, (4) parent scale 3 divisions, children Scale 1
2 divisions, (5) parent division 3 divisions, child division 15 divisions, (6)
There are 5 divisions on the parent scale and 15 divisions on the child scale. The scale display pattern 31 of FIGS. 9 to 12 corresponds to any of the above divisions (1) to (6).

21 and 22 show the lighting states of the parent scales 29b to 29k and the child scales 30a to 30N in the above divisions (1) to (6). The scale pattern 31 shown in FIGS. 9 to 12 can be realized by turning on the scale marked with a circle and turning off the scale marked with a minus sign. The parent scales 29a and 29l are not shown in FIGS. 21 and 22 because they are always lit in any case. Hereinafter, in the text as well, it is not particularly described as being in a constantly lit state.

The graduation division table 26 includes the graduation numbers and the parent graduation of the graduation display pattern 31 corresponding to the value of the primary rated current of the CT 12 or the value of the VT primary rated voltage shown in FIGS. 9 to 12 as described above. The turning-on / off position of and the turning-on / off position of the child scale are stored as data, and the value of the primary rated current of CT12 set in the maximum scale value setting unit 16 is stored in the scale division table 26 by the scale division calculation unit 25. It retrieves and retrieves the data.

Based on the data obtained by this search, the parent scale display control unit 27 displays the parent scales 29a to 29l and the child scale display control unit 28 displays the child scales 30a to 30N. 14, FIG. 15, FIG. 16, FIG. 17, FIG. 18, FIG. 19, and FIG. 20 No. 1 to No. 34 and No. 3
6 to No. 45.

For example, when the value of the primary side rated current of CT12 is 100 A, the display is as shown in the scale diagram No. 13 of FIG. That is, it corresponds to the pattern (1) shown in FIGS. 21 and 22, and has parent scales 29b, 29e, 29g, 29.
k and 29l are lit, and parent scales 29c, 29d, 29f,

It suffices to determine which one of (6) is applicable.

In FIG. 28, first, the set value of the maximum scale value setting unit 16 is C specified by JIS C1731.
It is checked whether the value is the primary value of T or VT (step 40). If there is no applicable item, JIS / C
Round to a value close to the specified value of 1731 (step 41).
For example, when the set value is AC14A, AC1 close to this is set.
Consider 5A as the set value. Since this is a check for the presence of erroneous settings, simply display an error message and
The setting of the maximum scale value setting unit 16 may be redone.

Next, the decimal point of the set value is removed (step 42) and the least significant digit "0" of the set value is removed. However,
If this value is "10", it is set to "10" (step 43). The value obtained by the processing of this step 43 is the value indicated by reference numeral 60 in FIG. The following division is executed using this value as the dividend, and the scale division types (1) to
Find (6).

In FIG. 27, divisors “9”, “8”, “5”,
The dividend by "4", "3", and "2" (value indicated by reference numeral 60)
When divided by, whether or not it can be divided is indicated by ○ and ×.

First, the value indicated by reference numeral 60 is divided by "3" (step 44). If it is divisible, it is further divided by "3" (step 45), and if it is divisible, the scale division type (3) is obtained (step 50). If it is not divisible, it is divided by "2" (step 46), and if it is divisible, it is the scale division type (4) (step 5).
1). If it is not divisible by "2", it is divided by "5" (step 47). If it is not divisible, it is again divided by "5" (step 48). If it is not divisible, it is the scale division type (6) (step). 52). If it is divisible, the scale division type (5) is set (step 53). Similarly, if division is not possible by the division of "5" (step 47), the scale division type (5) is similarly set (step 53).

Next, the division of "3" (step 44).
If it is not divisible by, divide by "5" (step 4)
9). If it is divisible by this, the scale division type (1) is obtained (step 54). If it is not divisible, the scale division type (2) is set (step 55).

Since the type of graduation division can be known from the above, based on this, as shown in FIGS.
.About.29k and sub-scales 30a to 30N are turned on or off (step 56).

Next, the scale number indicators 3a to 3g display the scale numbers shown in FIG. 24 based on the set value of the maximum scale value setting section 16 (step 57).

When the set value of 16 is exceeded, the operation is performed based on the stored value of the maximum value storage unit 34 this time. In the ninth embodiment, as shown in FIGS. 30 and 31, the set value of the maximum scale value setting unit 16 is set. Instead of using, the scale number calculation unit 17 and the unit calculation unit 19 calculate the scale number display and the unit display based on the stored value of the maximum value storage unit 34.

Example 10. Although not shown in the above-described eighth and ninth embodiments, the scale number calculation unit 17 and the unit calculation unit 19 are set so that the maximum scale value becomes a scale 1.5 times the stored value of the maximum value storage unit 34. , Scale division calculator 25

Example 11. In each of the above-mentioned embodiments, the division number and the division of the scale are divided so that the parent scale 29l corresponding to the maximum scale value has the maximum scale value. Scale division is performed as the scale value, and parent scale 29k and parent scale 29l
Is an extended scale. Further, the bar graph display 2 may be extended on the extension of the parent scale 29l to add an additional bar graph and an additional parent scale, and the additional bar graph and the additional parent scale may be used as the extended scale. The extended scale is an extended scale specified by JIS / C1102, which indicates the starting current on the extension of the rated current because the starting current flows through the indicating electric instrument used for the electric motor instrument. An extended scale is added for this purpose.

Example 12. In the above-described Embodiment 1 and the like, the unit indicator 4 is composed of the display portions 4a to 4d, but in the embodiment 12, as shown in FIG. 32, the unit indicator 4B.
