Description

  The present invention relates to an external notification device and a demand management system that monitor a current demand value, predict a future demand value, and notify the fact when there is a risk of exceeding a target demand value.

  In recent years, resource saving and energy saving have been desired, and in particular, reduction of electricity charges by power saving is also performed in ordinary households. By the way, the electricity charge is a charge obtained by adding the electricity charge to the basic charge, and the basic charge is a charge obtained by multiplying the basic charge unit price by the contract power. As for this contract power, the largest value among the demand values of the past 12 months is adopted as the contract power for the next one year. Here, the demand value refers to an average power (kW) for 30 minutes. For this reason, in order to reduce electricity charges, it is possible not only to reduce electricity consumption charges by reducing power consumption, but it is also possible to keep basic charges as low as possible by making efforts to reduce contract electricity .

  Therefore, conventionally, when the demand value is monitored and it is predicted that the target demand value will be exceeded, the fact is notified by an alarm lamp or the like, and the appliance that uses electricity unnecessarily is turned off. A demand management system has been developed that reduces electricity bills by calling attention.

For example, in Patent Document 1, the amount of power of the power demand monitoring target device is taken in, the current power amount, the predicted power at the end of demand monitoring are calculated, and the predicted power exceeds a preset power demand value. A technique is disclosed that determines whether or not the power demand value is exceeded and outputs a plurality of levels of alarms according to the degree.

The sound generated by the buzzer 33 is stopped by operating the buzzer stop button 34. The input / output terminal unit 35 receives an output terminal that generates an electrical signal when an alarm command corresponding to “CAUTION” is received from the demand management device 10, and an alarm command that corresponds to “LIMIT”. And an output terminal for generating an electrical signal.

  The external alarm device 50 is connected via a lead wire to an output terminal that generates an electrical signal when an alarm command corresponding to “caution” is received in the input / output terminal section 35 of the demand alarm device 30. An alarm command corresponding to “caution” transmitted from the demand management apparatus 10 is received via the demand alarm apparatus 30. The external alarm device 50 outputs a sound based on the alarm command from the demand alarm device 30, and notifies the user of the demand management device 10 of the occurrence of the alarm and the accompanying information regarding the alarm.

  FIG. 3 is a perspective view showing the internal configuration of the external alarm device. The external alarm device 50 has a configuration in which a speaker 52, an alarm generation circuit board 53, and a power supply circuit board 54 are installed in a casing 51, and a power plug 55 connected to the power supply circuit board 54 is provided outside the casing 51. It is. A plurality of slits 51 a are formed side by side on a part of the surface of the casing 51, and the speaker 52 is fixed in the casing 51 so as to face the slits 51 a. On the printed circuit board constituting the alarm generating circuit board 53, a receiving circuit for receiving a signal from the external alarm device 50, a recording circuit for recording a real voice, and an electric signal obtained by reproducing the voice recorded in the recording circuit are provided as a speaker. Various electric circuit elements constituting a circuit such as a reproduction circuit to be output to 52 are mounted. The power supply circuit board 54 converts the alternating current supplied by connecting the power plug 55 to a commercial power supply into a stabilized direct current of 6 V, for example, and supplies it to the alarm generation circuit board 53 and the speaker 52.

  FIG. 4 is a layout diagram of main electric elements mounted on the alarm generation circuit board. The alarm generation circuit board 53 includes a power input terminal 60, a recording status display LED 61, a recording / playback start point switch 62, a line output terminal 63, a speaker connection terminal 64, a condenser microphone 65, a recording / playback switch 66, and a line input selection. A switch 67, a line input terminal 68, a recording / playback changeover switch 69, and a control IC 70 are mounted. A lead wire is connected in parallel to the recording / playback switch 66, and this lead wire is connected to the input / output terminal portion 35 of the demand alarm device 30.

  The power input terminal 60 is connected to a 6 V stabilized DC power supply terminal by the power circuit board 54. The recording / playback start point switch 62 is a switch for determining a point at which recording / playback is started. The recording / playback changeover switch 69 is a switch for switching between a recording standby state and a playback standby state. When the recording / playback switching switch 69 is set to “REC”, the recording state display LED 61 is lit to enter the recording standby state. When “PLAY” is set, the recording state display LED 61 is turned off and the reproduction standby state is set.

  The line input selection switch 67 is a switch for setting whether or not to use a device connected to the line input terminal 68. For example, when recording a sound source from a device connected to the line input terminal 68, “LINEIN” is set. When the condenser microphone 65 mounted on the power circuit board 54 is used, the switch lever is always moved in the direction opposite to “LINEIN”. The recording / playback switch 66 is a switch for starting recording / playback. For example, when the recording / reproduction switch 69 is “REC”, the sound source is recorded in the memory of the control IC 70 while the recording / reproduction switch 66 is depressed. When the recording / playback switch 69 is “PLAY” and the recording / playback switch 66 is pressed once, the recorded content is played back. Further, by continuously pressing the recording / reproducing switch 66, the recorded contents are repeatedly reproduced. A reference point for starting recording or reproduction is determined by a recording / reproduction start point changeover switch 62. The playback time is the same number of seconds as the recorded time. Further, when recording (overwriting) is again performed on the recorded state, only the later recorded one is recorded, and the previous recording is deleted. The recording status display LED 61 is lit when the recording / playback switch 69 is “REC”. The condenser microphone 65 is used when the line input selection switch 67 is not set to “LINEIN”, and is recorded in the memory of the control IC 70 by inputting a real voice to be recorded toward the condenser microphone 65. The speaker connection terminal 64 is a terminal for connecting the speaker 52, and a sound composed of recorded electrical data is reproduced as audible data through the speaker 52. The line input terminal 68 is used when, for example, an external sound source such as a CD player is connected. The line output terminal 63 is used, for example, when connecting to an external power amplifier. In addition, since a lead wire is connected in parallel to the recording / reproducing switch 66, an electrical signal output from the demand alarm device 30 via the input / output terminal unit 35 operates the recording / reproducing switch 66. Has the same function as

  Next, operations for recording will be described. First, the case of recording using the mounted condenser microphone 65 will be described. First, as shown in FIG. 5, a 6 V stabilized DC power supply is connected to the power supply input terminal 60 by the power supply circuit board 54 so that the polarity is not mistaken. Next, the selection lever of the line input selection switch 67 is moved to a direction other than “LINEIN”. Next, the recording / reproduction start point changeover switch 62 is operated to set a point at which recording is to be started. In the present embodiment, recording for up to 60 seconds is possible, and by switching the recording / playback start point switch 62, it is possible to record / playback content within 20 seconds in three parts. . Next, the recording / playback switch 69 is set to “REC”. Next, while the recording / reproducing switch 66 is being pressed, a real voice is emitted toward the condenser microphone 65. While the recording / reproducing switch 66 is being pressed, a real voice is recorded, and recording is ended by releasing the pressing of the recording / reproducing switch 66.

  Next, the case of recording using line input will be described. First, as shown in FIG. 5, a sound source such as a CD player or an MD deck is connected to the line input terminal 68. Here, it is good to use a bin jack or a mini jack according to the cord to be used. Next, a 6V stabilized DC power supply is connected to the power supply input terminal 60 by the power supply circuit board 54 so that the polarity is not mistaken. Next, the line input selection switch 67 is set to “LINEIN”. Next, the recording / reproduction start point changeover switch 62 is operated to set a point at which recording is to be started. Next, the recording / playback switch 69 is set to “REC”. Then, the recording / reproducing switch 66 is pressed to record. While the recording / reproducing switch 66 is being pressed, the sound from the sound source is recorded, and the recording is ended by releasing the pressing of the recording / reproducing switch 66.

  Next, an operation for reproduction will be described. First, the case of reproducing using the mounted speaker 52 will be described. First, as shown in FIG. 6, the speaker 52 is connected to the speaker connection terminal 64. Next, the recording / playback start point changeover switch 62 is set to a point at which playback is to be started. Next, the recording / playback changeover switch 69 is switched to “PLAY”. Next, a 6V stabilized DC power supply is connected to the power supply input terminal 60 by the power supply circuit board 54 so that the polarity is not mistaken. Then, by pressing the recording / reproducing switch 66 once, the recorded content is reproduced to the end. If the recording / reproducing switch 66 is continuously pressed, the reproduction is repeated. Even if the recording / playback switch 66 is released during repeated playback, the recorded content is played back to the end without being played back, and the playback ends. Similarly, when the external alarm device 50 is connected to the demand alarm device 30, the recording / playback switch 66 is pressed by an electrical signal output from the demand alarm device 30 via the input / output terminal unit 35. The same function will be played, and the recorded content will be played to the end.

  Next, the case where the power amplifier 71 is connected to the speaker for reproduction will be described. First, as shown in FIG. 7, the power amplifier 71 is connected to the line output terminal 63. Connect “SP +” of line output terminal 63 to SIG or + of LINE input of power amplifier 71, and connect “GND” of LINE output terminal to “GND” or “−” of LINE input of power amplifier 71. To do. The recording / playback start point switch 62 is set to a point where playback is to be started. The recording / playback switch 69 is switched to “PLAY”. Next, a 6V stabilized DC power supply is connected to the power supply input terminal 60 by the power supply circuit board 54 so that the polarity is not mistaken. Then, by pressing the recording / reproducing switch 66 once, the recorded content is reproduced to the end. If the recording / reproducing switch 66 is continuously pressed, the reproduction is repeated. Even if the recording / playback switch 66 is released during repeated playback, the recorded content is played back to the end without being played back, and the playback ends. Similarly, when the external alarm device 50 is connected to the demand alarm device 30, the recording / playback switch 66 is pressed by an electrical signal output from the demand alarm device 30 via the input / output terminal unit 35. The same function will be played, and the recorded content will be played to the end.

  Next, the specific usage method of this embodiment and the case where it applies to a factory facility are demonstrated as an example. FIG. 8 is an explanatory diagram showing an arrangement example of the present embodiment in a factory, and the factory has three facilities of facility A, facility B, and facility C and a management room. Moreover, the demand management apparatus 10 is installed near the place where the watt-hour meter 100 (refer FIG. 1) is installed. In addition, a demand alarm device 30 is installed in the management room, and a signal is transmitted from the demand management device 10 by the power line conveyance method. An external alarm device 50 is installed on the side of the demand alarm device 30.

  In the demand management device 10, the demand value is monitored based on the power consumption of the entire factory facility, but it is difficult to grasp the power consumption of each of the equipment A, equipment B, and equipment C. For this reason, the use state of the electric power in each equipment A, equipment B, and equipment C is investigated. FIG. 9 is a graph showing an example of a change in the amount of electric power when the equipment A, equipment B, and equipment C are operated. In the example of FIG. 9, it can be seen that when equipment A, equipment B, and equipment C are simultaneously operated, the demand value is likely to exceed the predicted demand value around 12:00 pm. Here, when the power supply of the facility C is stopped, the demand value exceeds the target demand value, but when the power supply of the facility A is stopped, the demand value does not exceed the target demand value. Therefore, when the demand value is likely to exceed the target demand value, only the facility A needs to be stopped, and the facility to be stopped is specified.

  Then, the administrator opens the casing 51, operates various electrical components of the alarm generation circuit board 53, and records a message “Please stop the facility A” with the manager's voice. After recording, the recording / playback start point switch 62 is set to a point where playback is to be started, and the recording / playback switch 69 is switched to “PLAY”, and then the casing 51 is closed to enter a standby state. To do. Then, the demand management apparatus 10 monitors the current demand value and calculates a predicted demand value every predetermined time, for example, every 10 seconds. When the demand management device 10 detects that the predicted demand value has exceeded the target demand value, the demand management device 10 emits a yellow LED corresponding to “caution” on the alarm display unit 12 and also changes it to “caution”. A corresponding notification signal is transmitted to the demand alarm device 30. In the demand alarm device 30, the yellow LED 32 b corresponding to “caution” emits light and an intermittent sound “beep” is output from the buzzer 33. Further, when a current flows through a lead wire connecting the input / output terminal portion 35 of the demand alarm device 30 and the external alarm device 50, it functions in the same manner as when the recording / playback switch 66 is pressed, The administrator's voice is replayed via the speaker 52. By listening to this real voice, the administrator can grasp that the demand value may exceed the target demand value and the coping method of stopping the facility A. Then, the manager contacts the person in charge of the equipment A, gives an instruction to stop the equipment A, and the person in charge of the work who receives the notification from the manager stops the equipment A.

  Thereby, since the demand value in a factory falls, the predicted demand value which the demand management apparatus 10 calculates falls. When the predicted demand value becomes lower than the target demand value, the demand alarm device 30 emits the blue LED corresponding to “margin” and the blue LED 32a corresponding to “margin” in the demand alarm device 30 so as to emit light. Become.

  In addition, even if there is no sound from the external alarm device 50, the administrator can determine that the facility A needs to be stopped by the buzzer sound from the demand alarm device 30. However, the manager is not always resident in the management room, and an alternative employee may be in the management room. In this case, it becomes possible for the employee to determine that the facility A needs to be stopped by the voice from the external alarm device 50 saying “Please stop the facility A”. You can get in touch. Since the external alarm device 50 is provided with the line output terminal 63, the line output terminal 63 and a speaker close to the facility A are connected, and the voice “Please stop the facility A” is close to the facility A. You may make it output directly to a speaker.

  Further, depending on the factory, it may be necessary to operate the facility A depending on the time of day. In this case, since the external alarm device 50 can record three types of sounds, the output sound may be switched by opening the casing 51. Alternatively, as shown in FIG. 11, a plurality of external alarm devices 50 are connected in parallel to an output terminal that outputs a “caution” alarm command of the input / output terminal section 35 via the selector 73, and by operating the selector 73, The external alarm device 50 capable of outputting sound may be switchable. In this case, for example, an audio message “Please stop facility A” is output from the external alarm device 50a at around 12:00, and “Stop equipment B and facility C” from the external alarm device 50b at around 15:00. Audio may be output. In this way, it is possible to easily configure a management system in which alarm contents are output as voice data using real voice data.

  Furthermore, another external alarm device 50 is connected via a lead wire to an output terminal that generates an electrical signal when an alarm command corresponding to “limit” is received at the input / output terminal portion 35 of the demand alarm device 30. To do. Then, another external alarm device 50 may be made to output a voice saying “The limit is approaching. Stop the facility A sooner”.

  As described above, according to the present embodiment having the configuration described above, the demand management apparatus 10 monitors the demand value, predicts the demand value after 30 minutes every 10 seconds, and the predicted demand value is the target demand value. Can be notified by the alarm display unit of the demand management device 10, the demand alarm device 30 and the external alarm device 50 that the demand value may exceed the target value after 30 minutes. In particular, the external alarm device 50 externally attached to the demand alarm device 30 can notify the voice that the demand value may exceed the target value. Here, the external alarm device 50 has a recording / reproducing function of real voice data. For example, the name of the equipment to be turned off is recorded. Thereby, the voice output itself by the external alarm device 50 will notify that the demand value may exceed the target demand value, and by listening to the content of the real voice data emitted from the external alarm device 50, It is possible to easily grasp the countermeasure corresponding to the alarm. In this way, it is possible to reliably transmit the occurrence of an alarm for notifying that the demand value may exceed the target demand value in the future, and information accompanying the alarm, saving power, It will be possible to reduce charges.

  In addition, since it is possible to change the recorded content in the external alarm device 50, for example, when there is a layout change or equipment change in the floor, it is possible to cope with the changed environment.

  The recording operation in the external alarm device 50 is performed by operating various electrical components mounted on the alarm generation circuit board 53. Here, since the alarm generation circuit board 53 is covered with the casing 51, the recording function cannot be operated from the outside of the external alarm device 50 main body. Accordingly, it is possible to reduce the possibility that the recorded content is falsified by mischief or interest-oriented operation.
