Description

[Detailed description of the invention]

[Technical Field of the Invention] The present invention relates to a meter reading display device that can reduce the number of meter readings in a demand meter. [Technical Background of the Invention and Problems Therein] Conventional meters, for example, do not have equipment to record the amount of energy for multiple months, and the meters are read on a fixed day each month. This meter reading is; (regardless of the weather,
The same procedure had to be done for female birds, which was a difficult task for meter readers. As an expedient method to reduce the burden on meter readers, for example, it is possible to read the meter every other month and multiply the amount of electricity used for two months by V2 to display the amount of electricity used for one month. It could not be adopted easily because the system uses a pay-as-you-go rate system, where the rate varies significantly when the amount of electricity used exceeds a certain amount. [Object of the Invention] The present invention has been made in view of the above points, and it is possible to perform bimonthly meter reading by displaying the monthly loincloth required amount on different display sections and retaining this for at least two months. The purpose is to provide a meter reading display device that makes it possible. [Summary of the Invention] In order to achieve the above object, the meter reading display device of the present invention has the following features:
a pulse generation circuit that generates a pulse proportional to the demand;
A plurality of counters have a function of counting the pulses of this pulse generation t=+ path and a function of recording and considering the counted values, and a reset signal is applied to each of these counters at 1 o'clock of the 1st change of the month. , and add a hold signal to memorize and hold the counted value when the next month changes.
A timer circuit that sequentially sends the reset signal and the master gogo to a plurality of counters in accordance with the change of the month, and a separate display section that displays the count 1 recorded on each of the counters of the above-mentioned number of sheets. Adopts a configuration that includes a display circuit and a display circuit. [Examples of the Invention] Hereinafter, the present invention will be described in detail based on Examples with reference to the accompanying drawings. No. 1N is a block diagram showing the configuration when the meter reading display device according to the present invention is applied to, for example, a power consumption display device. 1. Count and record the counted value. t counters 11 and 12, and a reset signal and hold 1 to these counters 11 and +2, respectively.
A timer circuit 20 that outputs a monthly change signal whose level is inverted at the change of the month, and a timer circuit 20 that takes in the counts 11a stored in the counters 11 and 12, respectively, and a digit selection signal of these counters and a timer circuit. The display circuit 30 displays these counted values on two display sections based on twenty monthly signals. Among these, the timer circuit 20 includes a timer 21 that outputs a monthly change signal, and an N pulse that generates a pulse at the time of transition from an odd numbered month to an even numbered month based on the monthly change signal of this timer 21.
fll control signal and a pulse forming circuit 2 that obtains a control signal that generates a pulse at the time of transition from an even numbered month to an odd numbered month.
2, and an inverter 23 for inverting the 1 times sign on the open side.
24 and has metal fittings. The display circuit 30 also includes a signal synthesizer 31 that sequentially time-divisionally outputs the contents stored in the counters 11 and 12, and a monthly signal from the timer 21, which directly receives the monthly signal from the timer 21 via the cabinet inverter 34, so that the phase is Digit selectors 32 and 33 that output digit numbers 11 that differ by 180 degrees from each other; a decoder 35 that converts the output signals of the signal synthesizer 31 into signals corresponding to all display elements; and digit signals of the digit selectors 32 and 33. The display section 36 and 37 display the value obtained through the decoder 35 when the input signal is sent. FIG. 2 shows the operation of the power amount display device configured as described above.
This will be explained below with reference to FIGS. 8 and 4 as well. Note that the symbols a to j attached to the signal lines connecting the blocks in FIG. 1 correspond to the symbols representing the signals in FIG. 2 and FIG. '34, respectively. First, the timer 21 is set to L in odd-numbered months as shown in Figure 2a.
As shown in Figure 2 and e, the pulse forming circuit 22 outputs a monthly signal ai ratio whose level changes from 1 to 1 when the months change so that the level becomes H level in even months. Move to the moon (5)
-, '(, +19-) Outputs control signals C and d that generate a single pulse at the time of change, and θ, and outputs control signals C and d that generate a single pulse at the time of change from an even month to an odd month. Pulses proportional to the amount of power in the circuit 1 are simultaneously applied to the counters 11 and +2.Here, the counter 11 receives a control signal as a reset signal.
A control signal C obtained by inverting the control signal d by an inverter 23 is applied as a holding signal, and similarly, a control signal d is applied to the counter 12 as a reset signal, and a control signal b'6 is applied to the counter 12.
The control signal e inverted by the inverter 24 is added as a holding signal. Therefore, the counter 11 starts counting pulses at the same time as its contents are cleared at the time of transition from odd-numbered months to even-numbered months (1st, 8th, 5th, . . . end of November),
The time when an even numbered month changes to an odd numbered month (2, 4, 6...
. . . the end of December), and continues to hold it until the next holding signal is added (4, 6, 8, . . . the end of February). This means that at the beginning of January,

[February count value - (6) is deployed and the end of February! While maintaining the lever range, full counting of pulses begins at the beginning of February, and furthermore, the count value for February is stored at the beginning of August, and the count value is held until the end of April. On the other hand, the counter 12 indicates the point in time when an even numbered month changes to an odd numbered month (2, 4, 6......the end of December) FC
As soon as the contents are cleared, the number of pulses starts, and at the time of transition from an odd month to an even month (1, 8, 5,
The count value is recorded at the end of November), and the next holding signal is added (8, 5, 7...).
I will continue to hold this until the end of January. This means, for example, that at the beginning of February the count value for January is memorized and retained until the end of August, while at the beginning of August the number of pulses is started and then for the month of April. First, count values for August will be memorized, and this will be retained at the end of May. Next, the count content signals stored in the counters 1 and 12 are time-divided by the 1g synthesizer 31, and as shown in FIG.
and the count content signal B of the counter 12 are sequentially sent out at intervals of 5/1000 seconds, and are further applied simultaneously to the display sections 36 and 36 via the de]-2' half life=35. Also, digit selectors 32 and 331rJ:, , timer 2
Based on the month number signal a of 1, it is determined whether an odd numbered month is an even numbered month, and the digit selector "32 selects the digit number 100 g indicated in the fourth row in the even numbered month.
Add the digit signal 1 shown in Figure 1 to the odd numbered months to the display section 3, and add the digit selector 3]1 to the digit selector 3]. The digit signals J are respectively applied to the display section 37. As a result, the contents of the counter 11 are displayed on the display section 36 in even-numbered months.
Then, the contents of the counter I2 are displayed on the display section 37, respectively. For example, in February, the power amount for December of the previous year is displayed on the display section 36, and the power amount for January of the current year is displayed on the display section 37. Further, in odd-numbered months, the contents of the counter 11 are displayed on the display section 37, and the contents of the counter 12 are displayed on the display section 36, respectively. Therefore, in March,
The electric energy amount for January is displayed on the display section 36, and the electric energy amount for February is displayed on the display section 37. In other words, the display unit 36 is always configured to display the electric power amount for the month before the previous month, and the display unit 37 is configured to always display the total power consumption for the month, as shown in FIG. 8, for example. When the display unit 36 and the display unit 37 display the contents of the counter 11 and the counter 12 in a fixed manner, respectively, the electric energy for the month before the previous month and the previous month will be displayed in the even month. , which changes depending on the odd-numbered month, is ineffective in eliminating the steepness of the resistance. If such a 4i function @: display part # is added near the conventional electricity meter, it will always display the single-use electric energy for the month before the previous month and the previous month, making it easier to read the meter once every two months. This will reduce the number of meter readings by half, and also allow you to choose a day that is convenient for you or a day when the weather is clear. In addition, in the above embodiment, two counters and two display units were provided, and the meter was read once every two months, but the meter could also be read once every three months or more, as in the case of this example. The solar power indicator device can also be configured in substantially the same manner. Figure 5 is a diagram showing a partial configuration of an electric energy display device that reads the meter once every 3 months. The counters 11, 12, and I3 are each recorded with a total of 1 and 1]a) A signal synthesizer 31a that outputs all the time-divided signals on an instant basis, and a decoder (not shown) that outputs the time-divided synthesized signals. Display section 36.37.3B that displays n respectively.
and, for example, one for the counter 11.
A reset signal is added at the beginning of each month, April, etc., a holding signal kf: is added at the end of these months, and the reset signal is applied to the counter 12 at the end of each month, and February, May, etc.・・・・・・
A reset signal is added to the beginning of these months, a hold signal 1 is added to the end of these months, and 8 is added to the counter 13.
If the reset signal is set to 0 at the beginning of month, June, etc., and the holding signal m is set to 0 at the end of these months, the time keeping signals of these γt and others will be set to 1, m. The relationship between the retained contents is shown in FIG. In other words, counter llv'X, total count contents for January 2
Counter 2 holds the number of elbows for February for 8 months from the beginning of March to the end of May, and counter 13 holds 8 months from the beginning of March to the end of May. Monthly counts will be retained for eight months from the beginning of April to the end of June. On the other hand, for display R36, 37, and 38, n1 month, respectively.
In April..., the digit signals o, 'n q. shown in Figure 7 0.11), (1, , t, digit signals r, s, m, in August, June, etc.
In January 1, the digit signal shown by u, v, w, 1 input v,
If you add w, the electricity amount for the past 8 months will be displayed in the old column. In this way, it is possible to construct a power amount display device that can read the past three months' worth of power by just reading the meter once every eight months. In addition, in the two embodiments shown in Figure vJ1 and Figure 5, the count content f of the counter is time-divided and outputted by the signal synthesizer and added to the display at the same time. , it is possible to display the counting contents as they become older. FIG. 81 is a block diagram showing a partial configuration of an embodiment not based on a time division system, in which the same reference numerals as in FIG. Here, signal selectors 41 and 42 are used instead of the signal combiner, and the digit signal of the counter 11 is transferred to the digit selectors 32 and 3.
Similarly, the digit signals of the counter 12 are also simultaneously applied to the digit selectors 32 and 33. On the other hand, the count content signal of counter 11 is applied to signal selectors 41 and 42 simultaneously, and similarly, the count content signal of counter [2 is also applied to signal selectors 41 and 42 simultaneously. Here, when the monthly change signal a of the timer circuit 20 is at L level, that is, when the output of the inverter 34 is at H level, the digit selector 32 and signal selector 41 select the counter [2 digit signal and count content signal]. On the other hand, when the monthly 1M number a is at the HV level, that is, the output of the inverter 34 is at the L level, the digit signal and count content signal of the counter 11 can be passed through. Further, the digit selector 33 and the signal selector 42 can pass the digit signal and count content signal of the counter 11 when the monthly change signal a of the timer circuit 20 is at L level, and conversely, when the monthly change signal a of the timer circuit 20 is at the L level, When the signal a is at H level, the counter can pass the 2's digit signal and the count content signal. Thus, if the timer circuit 20 generates an L level signal in odd numbered months and an H level signal in western months as shown in Figure 2a, then the odd numbered months I/C will be displayed on the display section 36. In even months, the count contents of the counter 11 are displayed on the display section 37, and the count contents of the counter 11 are displayed on the display section 36, and the count contents of the counter 12 are displayed on the display section 3.
7, so lr'L is displayed. This means that a display method completely similar to that of the embodiment shown in FIG. 1 will be adopted.・Next, FIG. 9 is a block diagram showing the configuration of another embodiment according to the present invention, in which the count contents of the counter 11 that counts and holds the pulses of Fi even-numbered months are always displayed on the display. 36, the count contents of the counter 12 that counts and holds the pulses of odd-numbered months are always displayed on the display section 37 f'L.
In addition, a light emitting diode 43.44i is provided near the display section 36.37, and the monthly change of 1g of the timer circuit 20 is displayed.
The light emitting diodes 43 are turned on in odd numbered months, and all the light emitting diodes 44 are turned on in even numbered months. In this case, if it is determined that the display section on the side where the light emitting diode is lit will display the amount of electricity for the previous month, and the display section on the side where the light is off will display the amount of electricity for the month before the previous month. In addition, it is possible to eliminate the complexity at the time of obtaining the electric power S:a+, and it is also possible to further simplify the configuration of the display circuit. Here, if a light emitting diode is used as the display section 36, 37, 38 in the above embodiment, the display device can be housed within the case of a conventional watt-hour meter because the entire display device can be miniaturized. Although it is possible, if there is not enough room, for example, as shown in FIG.
You can pull out the conductor from this and install the main body of the power consumption display device after the counter outside the case, or you can
As shown in FIG. 1, the rotation speed of the rotating disk 51 of the watt-hour meter is detected by a sensor 52, and based on the signal from this sensor, it is converted into a pulse signal within the watt-hour display device main body 60. Needless to say, there are words that can have the same effect. [Effects of the Invention] As is clear from the above explanation, the meter reading display device of the present invention can display, for example, the amount of electric power used for commuting each month on different display sections, and Since the data is retained for two months, it is possible to accurately estimate the amount of electricity used each month by reading the meter once every two months or once every several months, especially in areas with inconvenient transportation or on remote islands. This has the excellent effect of significantly reducing the burden on personnel, and at the same time allowing meter reading contracts to be carried out on a convenient day or in good weather.
