Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an integration recording device that independently integrates and counts pulses from, for example, a power consumption meter with a transmitting device for each time period, and prints the counted contents at regular intervals.

In general, it is necessary for special customers in large power transactions to measure the integrated power amount by classifying it into three time periods: daytime, nighttime, and peak time.

For this reason, conventionally, as shown in FIG. 1, the emitted pulse from one power meter 1 with a transmitting device is passed through a three-time zone selector switch 2 for switching between the three time zones to three meters 3a, It is sent to the measuring device 3 consisting of 3b and 3c, and during the day,
Integrated display of power consumption during peak hours and at night.

However, with a device like the one shown in Figure 1, it is possible to know the amount of electricity used by time of day, for example, every month, but if you want to measure the amount of electricity used hourly in more detail,
This method requires a procedure of reading the values of the three measuring instruments 3a, 3b, and 3c every hour and calculating the difference between these readings and the previous reading, which is extremely troublesome and inefficient.

Particularly at a time when resource conservation is being called for these days, it is unsuitable for the detailed power monitoring described above.

Further, the conventional device must be equipped with a time switch in addition to the three-time zone selector switch 2, but since the time switch is mechanically driven, the time accuracy is undeniably lowered.

Furthermore, since the three measuring instruments 3a, 3b, and 3c are mechanically operated using electromagnets and ratchets, they are subjected to a large load due to wear and tear over time, and they also have disadvantages such as making a large noise when driven and consuming a large amount of current. .

The present invention has been made in view of the above-mentioned circumstances, and uses a time zone switching circuit to differentiate into multiple time zones, and an electronic counter to cumulatively measure the amount of power used in each of these time zones. It is an object of the present invention to provide an integration recording device that eliminates the above-mentioned drawbacks by eliminating a mechanical drive system and making the entire device electrically structured, such as by displaying the contents on a display.

Hereinafter, the present invention will be described in detail with reference to the drawings.

In FIG. 2, reference numeral 10 denotes a power consumption meter with a transmitting device that generates pulses for each predetermined unit of power consumption (pulses), to which is connected an integration recording device 20 for each time period that integrates and records the pulses. .

This integration recording device 20 includes a time zone switching circuit 21 that divides and outputs pulses from the electricity meter 10 with a transmitting device into three time zones, that is, daytime, peak time, and nighttime.
This is controlled by a time signal from an electronic time unit 22.

This electronic time device 22, for example, counts the commercial power frequency using a counter, and then divides the frequency of this count using a frequency dividing circuit to create a time signal.

A daytime counter 23, a peak counter 24, and a nighttime counter 25, which are divided into three time zones, are connected to the output side of this time zone switching circuit 21. The pulses generated are integrated and measured.

These counters 23.degree.24.25 are IC counters such as CMO8, for example.

Then, the values accumulated by the counters 23, 24, and 25 are displayed on an electro-optical daytime display 2 composed of light-emitting elements, etc.
6. The information is displayed on the peak display 27 and the nighttime display 28, and the contents are printed by the printing device 30 at fixed time intervals.

Next, FIG. 3 is a diagram specifically showing the time zone switching circuit 21, in which reference numeral 31 indicates an output terminal 31 when a specific time signal from the electronic time device 22 and a predetermined logic signal match.
This is a matching circuit that outputs matching signals (hereinafter referred to as clock pulses) to a and 31b.

That is, when the time signal reaches a predetermined value, the -number circuit 3
1 outputs a clock pulse.

For example, from 23:00 to 7:00 the next day at night, from 17:00
Peak time is 20:00, other times (7:00-17:00)
and 20:00 to 23:00) are the daytime hours, and when the electronic time device 22 reaches 7:00 and 23:00, a clock pulse is output from the output end 31a of the minus number circuit 31.

Also, when the time unit 22 reaches 17:00 and 20:00, a clock pulse is similarly output from the output terminal 31b of the matching circuit 31.

32 and 33 are first and second flip-flop circuits, and the signals obtained from these and the pulses from the electricity meter with transmitter 10 supplied to the terminal 34 are connected to a daytime gate circuit 35 consisting of an AND circuit, and a peak gate circuit 36,
It is supplied to the night gate circuit 37.

The output sides of these gate circuits 35, 36, 37 are connected to the daytime counter 23 through output terminals 38, 39, 40, respectively.
, a peak counter 24, and a night counter 25.

Next, the operation of the apparatus shown in FIG. 2 will be explained.

For example, when the time zone is set as described above, when the electronic time unit 22 reaches 7:00, a clock pulse is generated from the output terminal 31a by matching the logic of the minus number circuit 31, and the first flip Flop circuit 32 (hereinafter referred to as
A flip-flop circuit 32 is supplied thereto.

Therefore, the Q terminal of the foot flop circuit 32 is 1"
, the Q terminal becomes °0゛' (Fig. 4 32-Q, 32-Q
reference).

At this time, the second flip-flop circuit 33 (hereinafter simply referred to as flip-flop circuit 33) has not yet received the clock pulse from the coincidence circuit 31, so
The Q terminal of the flip-flop circuit 33 is O'' and the Q terminal is 1'' (see FIG. 4, 33-Q and 33-Q).

In this state, from the electricity meter with transmitter 10 to the terminal 34
When a pulse is supplied to the terminal 38, all the inputs of the daytime gate circuit 35 become 1'', and a ``1'' signal is generated from the terminal 38 when the conditions for the daytime time zone are satisfied.

That is, the pulses from the electricity meter 10 with the transmitting device pass through the time zone switching circuit 21 as they are, are integrated and measured by the daytime counter 23, and are displayed on the daytime display 26.

When a time signal of 17:00 is generated from the time unit 22 as time passes, a clock pulse is generated from the output terminal 31b side due to the coincidence signal from the minus number circuit 31, so that the Q terminal of the flip-flop circuit 33 becomes 11129. ,
Q terminal changes to 011 (Fig. 4 33-Q, 33-Q
reference).

In this state, from the electricity meter with transmitter 10 to the terminal 34
When a pulse is supplied to the terminal 39, the peak time period condition of the peak gate circuit 36 is satisfied, and the pulse is supplied to the terminal 39.
A signal is generated.

That is, the pulses from the power meter 10 with the transmitting device pass through the time zone switching circuit 21 as they are, are integrated and measured by the peak counter 24, and are displayed on the peak display 27.

Furthermore, as time passes, the time device 22 changes to 20:0.
When a time signal of 0 is generated, a clock pulse is output from the output terminal 31b due to the coincidence signal from the minus number circuit 31, and the Q terminal of the flip-flop circuit 33 becomes "O" and the Q terminal becomes "".
1'', and as in the beginning, when the conditions for the daytime time period of the gate circuit 35 are established, the pulses from the electricity meter 10 with transmitting device pass through the gate circuit 35 and are integrated and measured by the daytime counter 23.

Further, when the time unit 22 generates a time signal of 23:00, the coincidence signal from the - number circuit 31 causes the output terminal 31 to
A clock pulse is generated from a, whereby the Q terminal of the flip-flop circuit 32 becomes 1Qtl, and the Q terminal becomes 1''.
Therefore, after 23:00, the pulse from the electricity meter with transmitter 10 generates a "1" signal, that is, a pulse, from the night gate circuit 37, which is integrated and measured by the night counter 25 and displayed on the night display. 28.

In this manner, the pulses from the power meter 10 with transmitting device are switched to each time zone by the time zone switching circuit 21, and are integrated and measured by the counters 23, 24, 25 corresponding to the respective time zones.

Then, the time device 22 generates a print command signal at predetermined time intervals to operate the printing device 30, thereby printing out the contents of the counters 23, 24, and 25.

Further, since the contents of these counters 23, 24, and 25 are displayed on separately provided electro-optical displays 27, 28, and 29, the contents of the counters 23, 24, and 25 can be directly read as in the conventional case.

Note that it goes without saying that the device of the present invention is not limited to the above embodiments.

For example, two counters 23, 24, and 25 are each connected in parallel, and input pulses are supplied to them simultaneously for cumulative measurement. One of the counters is cleared to zero at each printing time, and the other counter is continuously integrated. Well, during the day,
Continuous integrated values for each time zone during peak hours and nighttime and integrated values for each time period are obtained and printed at the same time, thereby eliminating the trouble of calculating each hour as in the conventional method.

In this case, printing is performed as shown in FIG. 5, for example.

In addition, by making it possible to preset the minus number circuit 31 and setting the time period using a digital switch, etc., it is possible to know the integrated amount for each time period.

Furthermore, the display units 26, 27, and 28 are integrated, and the print command signal from the electronic time device 22 or the gate circuits 35 to 3
7 may be used to turn on a lamp or the like that indicates any of the daytime, peak, and night time periods.

As described in detail above, according to the present invention, when the time signal output from the electronic clock device reaches a predetermined time, a coincidence signal is outputted to control the daytime gate circuit, the peak gate circuit, and the nighttime gate circuit. By opening the circuit and allowing the input pulses to be cumulatively counted by the corresponding daytime counters, peak counters, and nighttime counters, the mechanical drive system for the cumulative counting means can be eliminated. This eliminates driving noise and also eliminates problems such as wear, improving durability and stability of operation.

In addition, since the conventional device is a mechanical switch, there is a transient phenomenon associated with the on/off of the switch, but in the case of the device of the present invention, the first and second Since the second flip-flop circuit is driven, the problem of transient phenomena is eliminated and the integrated count can be increased.

Furthermore, even if, for example, the number of time slots other than daytime, peak hours, and nighttime hours is increased due to rate policy, this can be easily accommodated by simply adding flip-flop circuits and gate circuits.

Moreover, the Q of the first and second flip-flop circuits,
Since both Q signals are used and applied to each gate circuit, accuracy can be increased and the number of flip-flop circuits can be reduced by one.

In other words, in a normal case, if each gate circuit were to add an input pulse and a signal of the relevant time period and output the input pulse, three flip-flop circuits would be required.
For the above reasons, only two pieces of this device are required.

In addition, although it is common to supply two inputs to each gate circuit, in this device, in addition to the input pulse and the signal for the relevant time period, by adding a signal indicating that it is not for other time periods, This greatly contributes to improving accuracy.

Furthermore, the amount of power used can be directly printed as an integrated amount of power for each hour, which eliminates the complexity of calculations and the like.

Although the present invention is mainly intended for measuring and printing the amount of electricity by time of day, it can also be used to measure the amount of water, gas, etc. used by time of day, and the number of users of public facilities such as stations by time of day. It is something that can be known.
