(Embodiment 1) In FIG. 1, numeral 1 indicates the power amount of a plurality of circuits from the first circuit to the n-th circuit from the voltages and currents of the plurality of circuits from the first circuit to the n-th circuit. The power amount measuring means 2 is a pulse counting means for counting first to n-th pulse inputs corresponding to the first circuit to the n-th circuit, and 3 is a pulse counting means for counting the first circuit to the n-th circuit.

Further, as in Embodiment 1, the power amounts of a plurality of circuits are added and subtracted to obtain a unit pulse power amount with one pulse input pulse, or a plurality of pulse inputs are added and subtracted to obtain one circuit. A unit pulse power may be obtained, or one unit pulse power may be obtained by adding or subtracting the power of a plurality of circuits and a plurality of pulse inputs.

Further, the ratio per pulse may be set as a multiplication factor. For example, when the unit price of one product to be produced is multiplied by one pulse, the power amount per money is obtained.

The electric energy measured by the electric energy measuring means 1 and the state detected by the detecting means 5 are input to the state-specific electric energy measuring means 6, and the electric energy measuring means 1 by the state-specific electric energy measuring means 6. The amount of power of the first circuit measured in step (1) is integrated for each state of the input level of the first state input detected by the detecting means 5 to determine the amount of power of the first circuit for each state. Each section is divided by a broken line in FIG. For example, if state A is the standby state of the machine tool, state B is the first step, and state C is the second step, the power consumption for each state is determined.
What has been troublesomely weighed while synchronizing the timing with a plurality of measuring instruments can be easily measured with one device. By adding the power amounts of the state B and the state C, the state A
The power consumption during standby and the power consumption during other operations are calculated, and the power consumption, which was previously known only in a large frame, can be analyzed in detail, which is useful for energy saving measures. It clarifies the process and points for improving the machine, and is effective in developing equipment with lower power consumption than before.

In another example, when a fluorescent lamp with a remote control switch is applied in place of the machine tool, the state A is a state where the remote control standby state is turned off, the state B is a two-step darker illuminance, and the state C is a brighter one. can do. If the amount of power consumption is known, depending on the use state, the main switch of the power supply is turned off to reduce the standby power at the time of turning off the light in the state A, or if the brightness does not pose a problem in actual use, change from the brighter to the darker. It becomes clear how much energy can be saved just by doing this.

In the third embodiment, the input to the electric power metering means 1 and the detecting means 5 has been described as an example using the first circuit and the first state input. However, a plurality of circuits and a plurality of state inputs may be used. Needless to say. The status input may be a command detection by communication.

Further, as in the first embodiment of the plurality of circuits, the electric energy may be added or subtracted, and the electric energy for each state may be obtained in the state of the first state input.

In this way, the power consumption during operation and during standby can be measured with a single device without the need for manual work such as switching between a plurality of devices and their inputs, so that it is simple. It is possible to realize a simple power consumption monitoring device and output it as digital data, which is useful for various displays and data processing. Above all, by measuring the amount of power required as a tool for energy saving, it is also useful for analyzing the actual situation of power consumption and understanding the standby power of equipment used to formulate energy saving measures when considering energy saving measures.

(Embodiment 4) In FIG. 5, the electric energy meter 1, the detector 5, and the state-specific electric energy meter 6 are shown in FIG.
Therefore, the description is omitted. Reference numeral 7 denotes a circuit channel setting unit that sets a combination of a voltage and current circuit input to the power amount measurement unit 1 and a state input input to the detection unit 5 in the state-specific power amount measurement unit 6.

The operation of the power consumption monitoring device configured as described above will be described with reference to FIGS. For example, when measuring the power consumption in each state of a certain machine tool, first, the voltage and current are input to the power metering means 1 as a first circuit from a power supply line of the machine. The power amount measuring means 1 calculates power from the first circuit voltage input and the first circuit current input, and integrates the power to obtain the power amount. As shown in the upper graph in FIG. 9, the electric power is integrated to obtain the electric energy.

The state of the device is input to the first state input of the detecting means 5. The detecting means 5 checks the level of the first state input, eliminates noise, and recognizes whether the input is a normal state input. As shown in the lower graph in FIG. 9, state input levels from level 1 to level 3 are detected.

The power amount measured by the power amount measuring means 1 and the state detected by the detecting means 5 are input to the state-specific power amount measuring means 6, and the state-specific power amount measuring means 6 outputs the power amount measuring means 1. The amount of power of the first circuit measured in step (1) is integrated for each state of the input level of the first state input detected by the detecting means 5 to determine the amount of power of the first circuit for each state. Each section is divided by a broken line in FIG. For example, if state A is the standby state of the machine tool, state B is the first step, and state C is the second step, the power consumption for each state is determined.
What has been troublesomely weighed while synchronizing the timing with a plurality of measuring instruments can be easily weighed with a single device. By adding the power amounts of the state B and the state C, the power consumption during standby in the state A and the power consumption during the other operation are obtained.
Since the amount of power consumption, which was previously known only on a large scale, can be analyzed in detail, it is useful for energy saving measures. It clarifies the process and points for improving the machine, and is effective in developing equipment with lower power consumption than before.

In another example, when a fluorescent lamp with a remote control switch is applied in place of the machine tool, the state A is a state where the remote control standby state is turned off, the state B is a two-step darker illuminance, and the state C is a brighter one. can do. If the amount of power consumption is known, depending on the use state, the main switch of the power supply is turned off to reduce the standby power at the time of turning off the light in the state A, or if the brightness does not pose a problem in actual use, change from the brighter to the darker. It becomes clear how much energy can be saved just by doing this.

Further, the input of a plurality of circuits is the electric energy metering means 1.
, And a plurality of state inputs are input to the detection means 5. The electric energy measured by the electric energy measuring means 1 and the state detected by the detecting means 5 are input to the electric energy measuring means 6 for each state, and are measured by the electric energy measuring means 1 by the electric energy measuring means 6 for each state. The detected electric energy is integrated for each state detected by the detecting means 5 to obtain an electric energy for each state.

On the other hand, the circuit channel setting means 7 sets a combination of the electric energy measuring circuit inputted to the electric energy measuring means 1 and each state input inputted to the detecting means 5.
For example, the first circuit and the third state input, the second circuit and the first state input, and the third circuit and the second circuit input are set.
Further, the same state input as the fourth circuit and the first state input may be set in a plurality of circuits.

Thus, the circuit channel setting means 7
By the setting according to the above, the state-specific power amount measuring means 6 obtains the state-specific power amount of each circuit. By providing the circuit channel setting means 7, even if the combination of the electric energy measurement input of a plurality of circuits and the plurality of state inputs is changed due to, for example, a change in the layout of a device or an input error due to a wiring construction error, the input wiring is changed. It is only necessary to change the setting by the circuit channel setting means 7 without performing the work, which leads to a significant reduction in the number of man-hours for change and a reduction in the construction cost.

Further, the state-specific electric energy obtained by the state-specific electric energy measuring means 6 may be displayed, remotely displayed at a remote place, output through communication, and subjected to various data processing by a computer.

Further, as in the first embodiment, the power amounts of a plurality of circuits may be added or subtracted, and the power amount for each state may be obtained with one state input.

In this way, it is not necessary to perform a human operation such as switching between a plurality of devices and their inputs, and a single device can measure the power consumption during operation and standby in any combination of inputs. Since it can be performed, a simple power consumption monitoring device can be realized, and can be output as digital data, which is useful for various displays and data processing. Above all, by measuring the amount of power required as a tool for energy saving, it is also useful for analyzing the actual situation of power consumption and understanding the standby power of equipment used to formulate energy saving measures when considering energy saving measures.

(Embodiment 5) In FIG. 6, the power amount measuring means 1, the detecting means 5, the state-specific power amount measuring means 6 and the circuit channel setting means 7 are the same as those in FIG. Reference numeral 8 denotes a state-specific input time integrating means for integrating and measuring the input time for each state input to the detecting means 5.

For example, suppose that the power consumption of each state of a certain machine tool is measured.

The state detected by the detecting means 5 is input to the state-specific input time integrating means 8 at the same time as the state-specific power amount measuring means 6 is input to the state-specific input time integrating means 8. The input time of the detected state is integrated for each state to obtain an integrated time for each state. In this case, the operation time of the device is determined by the integrated time of the state B and the state C, and the standby time of the device is determined by the integrated time of the state A.

Further, the integrated time for each state obtained by the input time integrating means 8 for each state may be displayed, remotely displayed at a remote place, output by communication, and various data processed by a computer.

Further, as in the first embodiment, the integration time for each state of a plurality of state inputs may be added or subtracted.

In this way, it is not necessary to perform a human operation such as switching a plurality of devices and their inputs, and a single device can measure the power consumption during operation and standby in any combination of inputs. Since it can be performed, a simple power consumption monitoring device can be realized.

Further, since it can be output as digital data, it is useful for various displays and data processing. Above all, by measuring the amount of power required as a tool for energy saving, it is also useful for analyzing the actual situation of power consumption and understanding the standby power of equipment used to formulate energy saving measures when considering energy saving measures. At the same time, the operating time and standby time of the equipment can be measured, so the operating rate of the equipment can be determined.

And the state-specific unit-time power amount calculating means 9 calculates the respective power amounts measured by the state-specific power amount measuring means 6 in accordance with the setting by the circuit channel setting means 7 by the state-specific input time integrating means 8. The amount of power per unit time for each state is calculated by dividing by the measured integration time for each state. In this case, the power consumption per unit time during operation of the device is obtained from the power amount in the state B and the state C and the integration time, and the power consumption per unit time in the standby state of the device with the power amount in the state A and the integration time. The quantity will be determined.

Furthermore, the unit time power consumption per state obtained by the unit time power consumption computing means 9 per state may be displayed, displayed remotely at a remote location, output by communication and processed by a computer for various data processing. Good.

Further, as in the first embodiment, the power amounts of a plurality of circuits may be added or subtracted, and the unit time power amount per state may be obtained by one state input.

In this way, the power consumption per unit time during operation and standby can be obtained with one device without the need for a plurality of devices and human work such as switching of inputs thereof. Therefore, a simple power consumption monitoring device can be realized, and can be output as digital data, which is useful for various displays and data processing.

Based on this data, the standby power can be reduced by further efficient operation of the equipment, and the productivity can be further improved. And energy saving can be promoted. Since the amount of power consumption per unit time is known, it is possible to estimate how much power is consumed when the operation time and the standby time are required, and it becomes easy to make a device operation plan.

(Embodiment 7) In FIG. 8, the power amount measuring means 1 and the pulse counting means 2 are the same as in FIG. 3, and the detecting means 5 is the same as in FIG. Reference numeral 10 denotes the electric energy measured by the electric energy measuring means 1 and the pulse counting means 2
Based on the number of pulses counted in the above, the state input by the detection means 5 is a unit pulse power amount in which the calculation of the power amount per pulse starts in the state B or the state C in FIG. It is an operation means.

The operation of the power consumption monitoring device configured as described above will be described with reference to FIGS.
For example, suppose that the amount of electric power used per product manufactured by a certain machine tool is measured.

The state A, the state B, or the state C is input to the detection means 5. The detection means 5 checks the level of the state input, eliminates noise, and recognizes whether the input is a legitimate input. Further, the voltages and currents of the plurality of circuits are input to the electric energy measuring unit 1, the plurality of pulse inputs are input to the pulse counting unit 2, and the states corresponding to the plurality of circuits are input to the detecting unit 5.

The power amount measured by the power amount measuring unit 1, the number of pulses counted by the pulse counting unit 2, and the state detected by the detecting unit 5 are represented by a unit pulse power amount calculating unit 10.
The pulse amount counted by the pulse counting unit 2 is the electric energy measured by the electric energy measuring unit 1 only when the state input to the detecting unit 5 by the unit pulse electric energy calculating unit 10 is the state B or the state C. The power per pulse is obtained by dividing by a number. When the state input to the detecting means 5 is in the state A, the operation is stopped. When the state is changed to the state B or the state C, the power per pulse is calculated again. Or continue from the previous calculation.

In this manner, the unit pulse power calculation means 10 obtains the unit pulse power in the states B and C of each circuit. In this case, for example, if the operating state of the production line is input to the detecting means 5, the amount of electric power per unit pulse used during operation of each produced product can be calculated.

On the other hand, the circuit channel setting means 11 sets a combination of a voltage and current circuit input to the electric energy measuring means 1, a pulse input to the pulse counting means 2 and a state input to the detecting means 5. .

For example, the first circuit, the third pulse input, and the second
State input, second circuit, first pulse input, third state input,
The third circuit, the second pulse input, and the first state input are set. The same channel may be set in a plurality of circuits, such as the fourth circuit, the first pulse input, and the first state input.

By providing the circuit channel setting means 11, the combination of the power amount measurement input of a plurality of circuits, the plurality of pulse count inputs, and the plurality of state inputs can be changed, for example, due to an input error due to a layout change of a manufacturing line or a wiring construction error. However, even if the setting is changed, it is only necessary to change the setting by the circuit channel setting means 11 without changing the input wiring, which leads to a drastic reduction in the number of man-hours for the change and a reduction in the construction cost.

Further, the unit pulse power amount calculating means 10
May be displayed, displayed remotely at a remote location, output through communication, and subjected to various data processing by a computer.

Further, as in Embodiment 1, the power amounts of a plurality of circuits are added and subtracted to obtain a unit pulse power amount with one pulse input, or the pulses of a plurality of pulse inputs are added and subtracted to add and subtract one pulse. A unit pulse power amount is obtained, and a power amount of a plurality of circuits is added to and subtracted from a pulse of a plurality of pulse inputs, and 1
Two unit pulse power amounts may be obtained.

The ratio per pulse may be set as a multiplication factor. For example, when the unit price of one product to be produced is multiplied by one pulse, the amount of power per unit of money is obtained. Furthermore, these can be controlled in a state of a plurality of channels.

In addition, applications such as taking in or out of a person or a vehicle by a pulse can be applied.

In this way, it is possible to measure the amount of power consumption per pulse only in an arbitrary state in an arbitrary combination of inputs with one device without requiring any human work with a plurality of devices. Therefore, a simple power consumption monitoring device can be realized, and can be output as digital data, which is useful for various displays and data processing. Among them, it is also useful for energy measurement and intensity management, which are necessary tools for energy saving.

When the material processing in the first machine tool 22 is completed, one pulse is input from the counter 25 to the pulse counting means 49 as processing information of the production number. The processed material is transferred to the next second machine tool 26. In this way, the material is transferred to the third machine tool 30 while being processed in the same manner, and the counter 46 counts non-defective products after the final inspection as finished products.

Then, the power amount measured by the power amount measuring unit 48 and the number of pulses counted by the pulse counting unit 49 are input to the unit pulse power amount calculating unit 51, and the unit pulse power amount calculating unit 51 outputs Weighed first

For example, if the state 1 is waiting for the machine tool, the state 2 is cutting, the state 3 is polishing, and the state 4 is assembling, the power consumption for each state is obtained. What was troublesomely measured while taking it can be easily measured with one unit. This makes it possible to analyze in detail the power consumption, which was conventionally known only on a large scale, and is useful for energy saving measures. In addition, since the processes that consume a large amount of power are clarified, it is possible to clarify the processes and points to be improved in order to reduce the power consumption of machine tools, and to develop equipment that leads to energy savings with lower power consumption than before. It is also effective.
Energy saving of the machine tool can be performed by replacing a component, for example, a motor or the like, in the machine unit 23 with an energy-saving type, or by improving a control program in the control unit 24 so as to eliminate useless operations. Since it becomes clear when each machine tool is on standby and during operation, energy saving can be achieved as a whole by improving the production process of the entire factory and performing efficient operation.

In addition to the machine tool, for example, in an air conditioner, information such as temperature, humidity, and human detection is input as state information, and one state is set from 10 ° to 20 °. By inputting the number of persons entering the room as a pulse, or by inputting the number of persons entering the room as a pulse, it is possible to perform analysis measures for efficient operation for energy saving measures.

In an elevator, for example, it is also possible to calculate the power consumption per person by inputting the number of users as a pulse or setting each floor to a state, or to calculate the power consumption used for each floor. it can.

In this way, by taking the object to be measured as the whole factory and each part as each device, it is possible to take a wider range of energy saving measures than before.

Conventionally, these measurements are performed by a plurality of personnel using a plurality of measuring instruments to synchronize the time. In the case of one measuring instrument, each part is sequentially measured and rotated. According to the present invention, since all of the above can be performed by one device, it is possible to quickly take measures and plan for energy saving improvement with a small number of people. By making early energy savings and reducing electricity bills, it is possible to make a significant contribution to the economy, environment and society.
