Description

  The present invention relates to an integrating device that integrates physical quantities such as heat quantity and flow rate and outputs a pulse every time the integrated value reaches a predetermined integrated value arrival point, and more particularly, pulse output pace (increased integrated value pace). It is related with the technique which makes it easy to recognize.

  Conventionally, there is a device called an integrated calorimeter. The integrating calorimeter is installed in a supply path such as cold / hot water, and calculates the amount of heat from the temperature and flow rate of the cold / hot water. An integrating calorimeter is one of measuring meters such as electricity, water, and gas, and is sometimes used for money transactions. Therefore, if the construction state is not correctly confirmed, there may be a case where a trouble occurs after the start of use.

  As one of the operation checks of the integrated calorimeter, it is necessary to check the output of the integrated pulse. In other words, since the integrated calorimeter outputs a pulse every time a predetermined amount of heat is integrated, it is necessary to check whether the pulse is output correctly. However, when the pulse output is extremely slow (for example, when the pulse interval is a few seconds or a few minutes), it takes a very long time to confirm. Therefore, a method of grasping how long it takes to output a pulse by displaying the integrated value numerically on a display device has been put into practical use (see Patent Document 1).

[Principle of Invention 1]
In the case of an integrated calorimeter, an amount that depends on two state quantities of temperature and flow rate is measured. Therefore, in particular, the pace at which the integrated heat amount increases (time interval for pulse output) cannot be assumed in advance, and the fluctuation range of the pace can be extremely large. Therefore, an integrated state display that is easy to recognize intuitively is preferable.

  Therefore, a display of a dimensionless quantity that can easily and clearly recognize the arrival point of the integrated heat quantity is added to the integrated calorimeter. Specifically, bar graph display (all lights when integrated heat reaches a predetermined integrated value arrival point), percentage display (100% display when integrated heat reaches a predetermined integrated value arrival point) ), LED display (all lights when the accumulated heat reaches a predetermined accumulated value arrival point) is adopted.

As is well known, in the integrated calorimeter, the amount of heat is integrated, and when the integrated heat amount reaches a predetermined integrated value arrival point (100%) as shown in FIG. A pulse is output as shown in FIG.
In the bar graph display of the present invention, a bar graph having a length corresponding to the integration rate, which is the elapsed rate of the integrated heat quantity with respect to the integrated value arrival point, is displayed. For example, in the examples of FIGS. 2A and 2B, the length L of the bar graph 100 changes according to the integration rate of 0%, 25%, 50%, 75%, and 100%, respectively. .

  In the percentage display of the present invention, the integration rate is displayed numerically. In the LED display of the present invention, the LED is lit for a time corresponding to the integration rate. For example, the examples of FIGS. 3A and 3B show that the LED lighting time T changes according to the integration rate of 0%, 25%, 50%, 75%, and 100%, respectively.

[Principle of Invention 2]
As described above, in the case of an integrated calorimeter, since the pace at which the integrated calorific value rises (the time interval at which pulses are output) cannot be assumed, there is more to be confirmed essentially. However, if it is limited to the confirmation of the integration status by bar graph display, percentage display, and LED display, it will be limited to merely intuitively confirming whether or not there is an operation.

  Therefore, the inventor has conceived that if the comparison reference pace is defined (for example, the change pace in the latest past performance) and the comparison reference pace is included in the display information, the accumulated pace itself can be confirmed.

  FIG. 4A and FIG. 4B are diagrams showing the relationship between the integrated heat quantity and the time interval at which pulses are output. In the figure, Q0 is a cumulative heat amount for comparison, and P0 is a pulse output according to the cumulative heat amount Q0. Q1 is an integrated heat quantity whose rising pace is faster than the comparative integrated heat quantity Q0, and P1 is a pulse output according to the integrated heat quantity Q1. Q2 is an integrated heat amount whose rising pace is slower than the integrated reference heat amount Q0, and P2 is a pulse output according to the integrated heat amount Q2.

[First Embodiment]
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 5 is a block diagram showing the configuration of the integrating device according to the first embodiment of the present invention. The present embodiment is an example corresponding to Principle 1 of the invention described above. The integrating device according to the present embodiment integrates an amount of heat and outputs an integration calculation unit 1 that outputs a pulse every time the integrated amount of heat reaches a predetermined integrated value arrival point, and an integrated value arrival point to be pulsed. A stored pulse output integrated value storage unit 2; an integrated rate calculating unit 3 that calculates an integrated rate that is an elapsed rate with respect to the integrated value arrival point of the integrated heat; a display processing unit 4 that performs display processing according to the integrated rate; It is composed of a bar graph meter, a display such as a liquid crystal, and an integration rate display unit 5 including LEDs.

  FIG. 6 is a block diagram showing the configuration of the input side of the integration calculation unit 1. Here, a case where the integrating device is an integrating calorimeter will be described. The integrated calorimeter is provided, for example, in a district cooling / heating system. The district cooling and heating system delivers a heat medium such as hot water to which heat energy is given by a heat supply (not shown) to a heat exchanger (not shown) serving as a heat load through the feed pipe 10a. Then, the heat medium that has consumed the heat energy for cooling and heating is returned again to the heat supply device through the return pipe 10b.

  On the input side of the integration calculation unit 1, a flow rate measurement unit 11 that measures the flow rate of the heat medium flowing through the return pipe 10b, a temperature sensor 12a that detects the temperature of the heat medium flowing into the heat exchanger through the feed pipe 10a, A temperature sensor 12b that detects the temperature of the heat medium that returns to the heat supply device through the return pipe 10b, and an A / D converter 13 that converts analog signals output from the temperature sensors 12a and 12b into digital signals are provided. .

  Hereinafter, the operation of the integrating device of the present embodiment will be described with reference to FIG. The integration calculation unit 1 calculates the amount of heat (step S100 in FIG. 7). Specifically, the flow rate measuring unit 11 measures the flow rate of the heat medium flowing through the return pipe 10b. On the other hand, the temperature sensor 12a detects the temperature of the heat medium flowing through the feed pipe 10a, and the temperature sensor 12b detects the temperature of the heat medium flowing through the return pipe 10b. The A / D converter 13 converts the analog temperature signal output from the temperature sensors 12a and 12b into a digital signal. The integration calculation unit 1 determines the flow rate of the heat medium measured by the flow rate measurement unit 11 and the temperature difference between before and after the heat load (that is, the temperature of the heat medium measured by the temperature sensor 12a and the temperature of the heat medium measured by the temperature sensor 12b). The heat consumption is calculated by multiplying the multiplication result by a predetermined heat amount conversion coefficient.

  Then, the integration calculation unit 1 integrates the calculated heat amount, and when the integration heat amount reaches the integration value arrival point stored in the pulse output integration value storage unit 2 (YES in step S101 in FIG. 7), a pulse is output. Output (step S102 in FIG. 7). In this way, a pulse is output each time a predetermined amount of heat is integrated. Needless to say, when the integrated heat amount reaches the integrated value arrival point and a pulse is output, the integrated heat amount is reset to 0, and the integration of the heat amount starts again.

On the other hand, the integration rate calculation unit 3 calculates an integration rate, which is an elapsed rate of the integration heat amount with respect to the integration value arrival point (step S103 in FIG. 7). If the integrated heat amount calculated by the integrated calculation unit 1 is Q, and the integrated value arrival point stored in the pulse output integrated value storage unit 2 is Qa, the integration rate R is expressed by the following equation.
R = Q / Qa (1)

  The display processing unit 4 performs display according to the integration rate R using the integration rate display unit 5 (step S104 in FIG. 7). For example, when displaying the bar graph, the display processing unit 4 does not display the bar graph when the integration rate R is 0%, and the bar with the length L corresponding to 25% when the integration rate R is 25%. A graph is displayed on the integration rate display unit 5 (for example, a bar graph meter). When the integration rate R is 50%, a bar graph having a length L corresponding to 50% is displayed on the integration rate display unit 5, and the integration rate R When L is 75%, a bar graph of length L corresponding to 75% is displayed on the integration rate display unit 5, and when the integration rate R is 100%, a bar graph of length L corresponding to 100% is displayed. It is displayed on the display unit 5.

  When performing the percentage display, the display processing unit 4 displays “0” on the integration rate display unit 5 (for example, a display) when the integration rate R is 0%, and displays the integration rate when the integration rate R is 25%. “25” is displayed on the unit 5, “50” is displayed on the integration rate display unit 5 when the integration rate R is 50%, and “75” is displayed on the integration rate display unit 5 when the integration rate R is 75%. When the integration rate R is 100%, “100” is displayed on the integration rate display unit 5.

  When performing LED display, the display processing unit 4 does not turn on the integration rate display unit 5 (LED) when the integration rate R is 0%, and the time corresponding to 25% when the integration rate R is 25%. The integration rate display unit 5 is lit only for T25. When the integration rate R is 50%, the integration rate display unit 5 is lit for the time T50 corresponding to 50%, and when the integration rate R is 75%, 75% is supported. When the integration rate R is 100%, the integration rate display unit 5 is lit for the time T100 corresponding to 100%.

  The processes in steps S100 to S104 as described above are repeatedly executed at regular intervals until the operation of the integrating device ends (YES in step S105 in FIG. 7).

  In the present embodiment, by displaying according to the integration rate R, an operator who wants to check the operation of the integration device intuitively recognizes how long it takes to output a pulse. can do. As a result, in this embodiment, even if the pulse output pace (the increasing pace of the integrated value) cannot be assumed in advance and the pulse output is extremely slow (for example, when the pulse interval is several seconds or several minutes), the integrating device It is possible to improve the ease of checking the operation.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. FIG. 8 is a block diagram showing the configuration of the integrating device according to the second embodiment of the present invention. The same components as those in FIG. The present embodiment is an example corresponding to Principle 2 of the invention described above. The integration device according to the present embodiment includes an integration calculation unit 1, a pulse output integrated value storage unit 2, an integration rate calculation unit 3, a display processing unit 4a, a color graph compatible bar graph meter, and a color display compatible display. An integration rate display unit 5a composed of a plurality of LEDs having different emission colors, an integration elapsed time measurement unit 6 that measures an integration elapsed time that is an elapsed time from when the integration calculation unit 1 outputs a pulse, and an integration calculation A comparison reference pace storage unit 7 that stores a reference pulse interval time of pulses output from the unit 1, and an accumulated elapsed time measurement unit 6 is stored in the accumulated elapsed time and comparison reference pace storage unit 7 during measurement. And a comparison reference pace rate calculation unit 8 for calculating a comparison reference pace rate which is a ratio to the pulse interval time.

  Next, the operation of the integrating device of the present embodiment will be described with reference to FIG. The operation of integration calculation unit 1 (steps S200 to S202 in FIG. 9) and the operation of integration rate calculation unit 3 (step S204 in FIG. 9) are as described in the first embodiment.

  The accumulated elapsed time measuring unit 6 starts measuring the accumulated elapsed time ta when the accumulated calculating unit 1 outputs a pulse (step S203 in FIG. 9). In the example of FIGS. 1A and 1B, measurement of the accumulated elapsed time ta is started at timings t1, t2, t3, t4, t5, and t6. Needless to say, when the next pulse is output, the accumulated elapsed time ta is reset to 0, and the measurement of the accumulated elapsed time ta is started again.

  The comparison reference pace storage unit 7 stores a reference pulse interval time tref of pulses output from the integration calculation unit 1. As an example of the reference pulse interval time tref, there is a previous pulse interval time (the latest record). In the example of FIGS. 1A and 1B, if the current time is between t4 and t5, the reference pulse interval time tref is the time from t3 to t4.

  When the previous pulse interval time is used as a reference pulse interval time tref, pulse interval time measuring means (not shown) for measuring the pulse interval time from when a certain pulse is output until the next pulse is output is provided. It is necessary to provide it inside the integration calculation unit 1. The comparison reference pace storage unit 7 stores the latest pulse interval time measured by the pulse interval time measuring unit as a reference pulse interval time tref.

Further, as another example of the reference pulse interval time tref, there is an average value calculated from past results (for example, the average value of the last 10 pulse interval times). In this case, it is necessary to provide the above-mentioned pulse interval time measuring means and the average value calculating means (not shown) for calculating the average value of the last 10 pulse interval times inside the integration calculating unit 1. . The comparison reference pace storage unit 7 stores the latest average value calculated by the average value calculation means as a reference pulse interval time tref.
Further, the reference pulse interval time tref may be registered in advance in the comparison reference pace storage unit 7 as a fixed value.

The comparison reference pace rate calculation unit 8 is a comparison reference pace that is a ratio between the integration elapsed time ta being measured by the integration elapsed time measurement unit 6 and the reference pulse interval time tref stored in the comparison reference pace storage unit 7. The rate Rref is calculated by the following equation (step S205 in FIG. 9).
Rref = ta / tref (2)

  The display processing unit 4a performs display according to the integration rate R and the comparison reference pace rate Rref using the integration rate display unit 5a (step S206 in FIG. 9). For example, when displaying a bar graph, the display processing unit 4a displays a bar graph having a length L corresponding to the integration rate R in the same way as in the first embodiment, for example, an integration rate display unit 5a (for example, a bar graph meter for color display). At the same time, the color of the bar graph is changed depending on whether the integrated rate R is greater than or less than the comparison reference pace rate Rref. For example, a red bar graph is displayed when the integration rate R is equal to or higher than the comparison reference pace rate Rref, and a green bar graph is displayed when the integration rate R is less than the comparison reference pace rate Rref.

  When performing the percentage display, the display processing unit 4a displays the integration rate R as a numerical value on the integration rate display unit 5a (for example, a display compatible with color display) and compares the integration rate R as in the first embodiment. The color of the numerical value to be displayed is changed depending on whether it is greater than or less than the reference pace rate Rref. For example, when the integration rate R is equal to or higher than the comparison reference pace rate Rref, the integration rate R is displayed in red, and when the integration rate R is less than the comparison reference pace rate Rref, the integration rate R is displayed in green.

  When performing LED display, the display processing unit 4a turns on the integration rate display unit 5a (a plurality of LEDs having different emission colors) for the time T corresponding to the integration rate R as in the first embodiment. The LEDs having different colors are turned on depending on whether the rate R is equal to or less than the comparison reference pace rate Rref. For example, when the integration rate R is equal to or higher than the comparison reference pace rate Rref, the red LED is turned on, and when the integration rate R is less than the comparison reference pace rate Rref, the green LED is turned on.

  The processes in steps S200 to S206 as described above are repeatedly executed at regular intervals until the operation of the integrating device is completed (YES in step S207 in FIG. 9).

  In the present embodiment, the same effect as in the first embodiment can be obtained, and the display color is changed depending on whether the integration rate R is equal to or less than the comparison reference pace rate Rref. It can be confirmed whether the rate of increase in the integrated heat amount is faster or slower than the comparative reference pace.

Simultaneously with the display according to the integration rate R, the display processing unit 4b uses the comparison reference pace rate display unit 9 to display according to the comparison reference pace rate Rref (step S307 in FIG. 11).

For example, when the bar graph display is performed, the display processing unit 4b displays the bar graph having the length L corresponding to the comparison reference pace rate Rref in the same manner as the display according to the integration rate R, for example, the comparison reference pace rate display unit 9 (for example, (Graph meter)
When performing the percentage display, the display processing unit 4b displays the comparison reference pace rate Rref as a numerical value on the comparison reference pace rate display unit 9 (for example, a display) in the same manner as the numerical display of the integration rate R.
