Here said " accumulative total electric power amount upper limit set value " is meant the consumption electric power value as every month energy conservation object of household electrical appliance, when interlock setting sign 106d is set at " 1 ", by relatively calculating part 114 controls, in principle, stops power supply when surpassing this value.Here said " accumulative total electric power value ".Being meant the electric power amount aggregate-value of actual consumption in the household electrical appliance, is the value of upgrading per schedule time (for example 1 minute).Here said " interlock set sign " is meant for each household electrical appliance, whether makes it and electrical management device 10 interlocks and implements energy-conservation sign, set by the occupant.Implement to be set at " 1 " when energy-conservation, do not implement to be set at " 0 " when energy-conservation.Here said " relative importance value " is meant the value of the degree of difficulty of expression when judging whether as energy-conservation object, " 0 " expression relative importance value the highest (that is) least easily as energy-conservation object, and numerical value is big more, relative importance value low more (that is, the easiest of energy-conservation object).At this moment, be the household electrical appliance of " 0 " for relative importance value, from energy-conservation object, remove (for example refrigerator etc.).Therefore, from the big household electrical appliance of relative importance value value, in turn as energy-conservation object.Here said " accumulative total total amount of power upper limit desired value " is meant every month overall consumption electric power amount desired value of family, when surpassing this value, from the big household electrical appliance of relative importance value value, implements strategy of Saving Energy.
Below, the action of above-mentioned electrical management device 10 is described.
Power measurement control device 110, insert as the household electrical appliance 210 of energy-conservation object and between the plug 202 of these household electrical appliance 210 power supplies, like this, accumulative total power measurement portion 111 begins to offset the measurement of power consumption strength aggregate-value.Its measurement result, is delivered to and is set display device 100 by lamp cord 200 from lamp cord Department of Communication Force 113, shows that by display part 101 like this, the occupant can confirm the consumption electric power amount of household electrical appliance 210.After the occupant has seen this demonstration, when wanting to stop the power supply to household electrical appliance 210, the operation of " power supply stops " being carried out in configuration part 102.Like this, control part 104 produces open and close controlling signal " 1 (switch 116: open) " according to occupant's operation, delivers to power measurement control device 110 by lamp cord 200.So, receive the lamp cord Department of Communication Force 113 of the power measurement control device 110 of open and close controlling signal, this open and close controlling signal is delivered to break-make control part 115, so, switch 116 can be controlled to be " opening ".At this moment, even the operator that position and operating and setting display device 100 are set of household electrical appliance 210 leaves far, its operation also is easy to.For example, with the setting display device 100 of Stall, affirmation is located at the accumulative total electric power amount of the household electrical appliance 210 of second floor, the operation that can power and stop.In addition, the open and-shut mode of break-make control part 115 also can be confirmed by display part 101, so, can 102 energisings easily from the configuration part, make the household electrical appliance action again.
The following describes the energy-conservation action of considering convenience.As previously mentioned, the occupant is when setting display device 100 and confirm on one side that totally electric power amount etc. is operated household electrical appliance 210, owing to from the operating state that compares the household electrical appliance between short-term, judge, cut down holding state power consumption, do not forget when leaving the house that closing electrical equipment etc. is more effective way, but, only depend on and so still can not get sufficient energy-saving effect.Must in a planned way judge from long-term operating state, carry out energy-conservation.For example, in advance each household electrical appliance is set the consumption electric power amount higher limit of every month,, when electric power amount aggregate-value surpasses its higher limit, cut off power supply automatically, be only so effectively.In this example, have comparison calculating part 114 corresponding to this situation.According to the occupant's who receives by configuration part 102 operation, set the accumulative total electric power amount upper limit set value of household electrical appliance 210, and be stored in the storage part 105.Simultaneously, also set and store the effective interlock of the interlock that whether makes this upper limit set value and above-mentioned break-make and set sign.As mentioned above, make that the value that interlock is set sign is set at " 1 " with accumulative total electric power amount higher limit interlock, when carrying out Energy Saving Control, be not set at during interlock " 0 ".
Fig. 4 is a process flow diagram, expression and the treatment scheme that adds up in electric power amount higher limit interlock, the comparison calculating part 114 when carrying out Energy Saving Control.At first, lamp cord Department of Communication Force 113, input is set sign (S401) with any period (for example one-second period) or random time from accumulative total electric power amount upper limit set value and interlock that setting device 100 is sent here by lamp cord 200.Even interlock is set and is indicated when being set at " 0 (not interlock) " (S402:No) Energy Saving Control under unreal the imposing if accumulative total electric power amount higher limit is set.
Then, relatively calculating part 114 is accepted the accumulative total electric power value of sending here from accumulative total power measurement portion 111 (S403).If when accumulative total electric power value surpasses accumulative total electric power amount higher limit (S404:Yes), then open (cut-out) switch 116, give break-make control part 115 (S405) open and close controlling signal " 1 ".By this action, stop to household electrical appliance 210 power supplies.
In addition,,, the zero setting signal can be sent, accumulative total electric power value zero setting constantly can be somebody's turn to do by with the operation of random time from occupant's acceptance in accumulative total power measurement portion 111.This zero setting signal is before calculating part 114 actions relatively or the utilization when surpassing higher limit etc. of accumulative total electric power value.
In addition, compile the consumption electric power amount of whole household electrical appliance in the family, when this accumulative total electric power amount of compiling the result surpasses certain value,, stop power supply successively, carry out Energy Saving Control from unessential (being that relative importance value is low) household electrical appliance.
Fig. 5 is according to above-mentioned accumulative total total amount of power and relative importance value, the signal procedure figure between the setting display device-power measurement control device when carrying out Energy Saving Control.
At first, set 100 pairs of household electrical appliance 51 of display device and require it to send accumulative total electric power value, accept its accumulative total electric power value (S501, S502) again.Similarly, set display device 100 and require its household electrical appliance 210 to propose to send accumulative total electric power value, accept its accumulative total electric power value (S503, S504) again.Then, set display device 100 and compile the accumulative total electric power value (S505) of these electrical equipment, when this value has surpassed this month to date total amount of power upper limit desired value 107a (S506) that is stored in the storage part 105, determine the big household electrical appliance (S507) of value of relative importance value 106e, the open and close controlling signal is delivered to its power measurement control device (S508), stop its power supply (S509).
As mentioned above, electrical management device 10 according to the invention process form 1, can not only measure the consumption electric power amount of household electrical appliance 210, and the signal of the setting display device 100 of available occupant's operation, cut off energising, so the occupant has seen that the supervision that consumes electric power is as a result the time, needn't directly go to the position that is provided with of electrical equipment and operate, just can realize energy-conservation.In addition, can control the energising of household electrical appliance linkedly with the consumption electric power amount higher limit that the occupant sets, so, can realize convenient economize on electricity.(example 2)
In this example, use air-conditioning as household electrical appliance.Usually, among the electrical equipment that family uses, what consume electric power amount ratio maximum is air-conditioning.Therefore, when considering family's economize on electricity, the economize on electricity of air-conditioning must be considered.But air-conditioning is the electrical equipment that directly forms the room hot-cool environment, so, only stop the action of itself, can bring uncomfortable sensation to the occupant.For this reason, in the time of saving the power consumption of air-conditioning, require to control subtly the adjusting of design temperature, the adjusting of air quantity etc.
At this problem, among the present invention, the infrared remote controller that utilizes air-conditioning to have is not only controlled beginning to body power supply/stop, and also carries out the control of setting range with infrared remote controller, like this, carries out energy conservation control.
Fig. 6 is the outside drawing of the air-conditioning structure in this example.As shown in Figure 6, this air-conditioning 160 is powered by power measurement control device 310 and plug 161.Power measurement control device 310 is connected with setting display device 300 by lamp cord 300.The infrared ray acceptance division of air-conditioning 160 is prevented to cover 125 by the infrared ray reception and is covered with, so, can not directly receive infrared signal from telepilot.For this reason, receive remote controller signal in order to make power measurement control device 310, and supply with infrared signal to air-conditioning 160,, be provided with signal relay device 126 with infrared ray acceptance division 123 and illuminating part (figure does not show) in the side of air-conditioning 160 by optical fiber 124.
Fig. 7 is the block diagram of electrical management device 20 structures in the expression example.Electrical management device 20 in this example with the difference of electrical management device 10 in the example 1, is as household electrical appliance with air-conditioning 160.In addition, in the following description, with identical construction in the example 1, annotate with same tag, its explanation is omitted.
In the electrical management device 30 of this example, unexistent neotectonics in example 1, it is air-conditioning 160 as the electrical management object, plug 161 to the air-conditioning power supply, the infrared remote controller 162 that the occupant uses air-conditioning 160, the ultrared infrared ray acceptance division 123 of receiving infrared-ray telepilot 162, directly obtain the signal that receives by infrared ray acceptance division 123, and the remote signal obtaining section 122 of giving lamp cord Department of Communication Force 113 as air-conditioning set condition data, receive air-conditioning set condition data and be used to make from the remote signal efferent 120 of the infrared signal of infrared luminous part irradiation, infrared ray acceptance division to air-conditioning sends ultrared infrared luminous part 121, the infrared ray that infrared luminous part 121 is sent is given the optical fiber 124 of air-conditioning infrared ray acceptance division, the infrared ray that makes infrared ray directly not enter air-conditioning infrared ray acceptance division receives and to prevent to cover 125 etc.
Set the function of display device 300, the setting display device 100 with example 1 is identical basically, but in order to control according to the various signals of infrared remote controller 162, has correspondingly enlarged the function of control part 304 and storage part 305.
In addition, lamp cord Department of Communication Force 313 in the power measurement control device 310 and the basic function that compares calculating part 314, also lamp cord Department of Communication Force 113 and the comparison calculating part 114 with example 1 is identical, but, with the various control signals of infrared remote controller 162 correspondingly, increased the functions such as reception of the generation of air-conditioning control data and transmitting-receiving, air-conditioning set condition data.
Remote signal efferent 120 according to the relatively indication of calculating part 314 or lamp cord Department of Communication Force 313, produces the control signal of control air-conditioning 160, and gives infrared luminous part 121.In addition, remote signal efferent 120 when not carrying out Energy Saving Control, the control signal of sending here from remote signal obtaining section 122, is intactly given infrared luminous part 121.

Below, the action of above-mentioned electrical management device 30 is described.At first, power measurement control device 310 is inserted between the plug 202 and air-conditioning 160 of air-conditioning 160 power supplies the measurement that accumulative total power measurement portion 111 begins to consume electric power amount aggregate-value.This measurement result, is shown by the display part 101 of setting display device 300 through lamp cord 200 from lamp cord Department of Communication Force 313, points out the electric power consumption of air-conditioning 160 to the occupant.
In addition, the setting content that receives from the infrared remote controller 162 in Japanese room for example to air-conditioning 160, obtained by the infrared ray acceptance division 123 of power measurement control device 110 and remote signal obtaining section 122, from lamp cord Department of Communication Force 113 process lamp cords 200, show by the display part 101 of setting display device, so the people in the living room for example also can monitor the setting content of air-conditioning 160.In addition, setting content to air-conditioning 160, the normally operation mode of the ON/OFF that sets with the infrared remote controller of air-conditioning of occupant, cooling/heating etc., design temperature, air quantity, wind direction etc., these setting contents are delivered to lamp cord Department of Communication Force 313 as air-conditioning set condition data from remote signal obtaining section 122.
Because being installed, the infrared ray reception prevents to cover 125 on air-conditioning 160, so, the infrared signal that receives from the occupant, directly do not enter the infrared ray acceptance division of air-conditioning 160, but receive by the infrared ray acceptance division 123 of power measurement control device 310, through remote signal obtaining section 122, remote signal efferent 120, infrared luminous part 121 and optical fiber 124, deliver to the acceptance division of air-conditioning 160, handle.Therefore, the set condition of air-conditioning 160 is consistent with the air-conditioning set condition of being grasped by remote signal obtaining section 122.
When the occupant wants to make air-conditioning 160 economize on electricitys, see the electric power consumption of the air-conditioning 160 that the display part 101 of setting display device 300 shows and the set condition of air-conditioning 160, when the operation of its design temperature is changed in configuration part 102, this content of operation is by the lamp cord Department of Communication Force 313 of setting display device 300 and the lamp cord Department of Communication Force 313 of lamp cord 200 and power measurement control device 310, deliver to remote signal efferent 120, can carry out the control of air-conditioning 160.For example, in when refrigeration, when carrying out that for economize on electricity design temperature improved 1 ℃ setting, can carry out this setting to the air-conditioning 160 that is positioned at second floor by the setting display device 100 in the Stall room.
In addition, relatively calculating part 114 also can have electric power consumption when air-conditioning and surpassed certain in limited time, automatically the function of cut-out.Specifically, set the control part 304 of display device 300, accept the accumulative total electric power amount upper limit set value that the occupant sets air-conditioning 160 by configuration part 102.Simultaneously, also accept the setting that interlock is set sign.
Fig. 8 is a process flow diagram, represents to compare in this example the treatment scheme of calculating part 314.At first, relatively calculating part 314 receives air-conditioning set condition data from remote signal obtaining section 122, judges whether the power supply of air-conditioning 160 connects (S801).Then, relatively calculating part 314 is accepted from setting accumulative total electric power amount upper limit set value and the interlock setting sign (S802) that display device 300 is sent here by lamp cord.When being masked as " 1 ", the interlock setting (S803:Yes) and from accumulative total power measurement portion 111 accepts accumulative total electric power values, when this accumulative total electric power value has surpassed accumulative total electric power amount upper limit set value (S805:Yes), for air-conditioning is stopped, sending the air-conditioning control data (S806) of " energy saver mode " usefulness to remote signal efferent 120.The air-conditioning control data of said here " energy saver mode " usefulness for example is by suppressing design temperature or air quantity, suppressing the control data of power consumption.
Like this, remote signal efferent 120 generates the control signal of " energy saver mode " usefulness and gives infrared luminous part 121.By the infrared ray that infrared ray acceptance division 123 generates, deliver to air-conditioning 160 through optical fiber 124, air-conditioning begins Be Controlled.The air-conditioning control data of said here " energy saver mode " usefulness also can be the control that makes the air-conditioning outage.In addition, even after once having set accumulative total electric power amount higher limit, also can make Energy Saving Control invalid by the interlock sign being set at " 0 " (not interlock).
Accumulative total power measurement portion 111 can 102 send the zero setting signal from the configuration part in time arbitrarily, this accumulative total electric power value zero setting constantly.Therefore, before calculating part 114 actions relatively or the utilization such as when surpassing higher limit of accumulative total power value, be effectively.
As mentioned above, according to the electrical management device 20 of example 2, power measurement control device 110 is not only measured the electric power consumption of air-conditioning 160, and can carry out the setting to air-conditioning with the signal of the setting display device 100 of occupant operation.Therefore, the occupant can confirm the set condition of electric power consumption and present air-conditioning, needn't directly go to the position of air-conditioning and operate, and also can realize energy-conservation.In addition, owing to can control the setting of air-conditioning linkedly with the consumption electric power higher limit that the occupant sets, the control electric power consumption, so, can realize energy-conservation more easily.(example 3)
Fig. 9 is the block diagram of electrical management device 30 structures of expression example 3.The difference of the electrical management device of example 3 and example 2 is, increased or not pick-up unit 140.Like this, can provide and do not reduce occupant's comfort as far as possible, realize energy-conservation electrical management device.In the following description, with part identical in the example 2, annotate with same tag, its explanation is omitted.
Or not pick-up unit 140, constitute by infrared ray sensor 130, sensor signal detection portion 131, lamp cord Department of Communication Force 141.By infrared ray sensor 130 human body is detected as hot object, judge that by sensor signal detection portion 131 human body is whether in the surveyed area of infrared ray sensor.Usually, surveyed area is that Zone Full in the house of air-conditioning is being set.The signal that sensor signal detection portion 131 sends is that human body is in the room or not at the signal in room.
Plug 183 is connected on the socket 202, should just beginning action at pick-up unit 140, obtain from sensor signal detection portion 131 or not signal, pass through the lamp cord 200 that lamp cord Department of Communication Force 141 is delivered in the family.Deliver to lamp cord 200 or not signal, can receive by the lamp cord Department of Communication Force 113 of power measurement control device 110.Therefore, can not be provided with away from the power measurement control device 110 that is located at air-conditioning 160 next doors, for example can be arranged on the place that ceiling etc. is convenient to human body at pick-up unit 140.Set display device 100, power measurement control device 110, identical with electrical management device in the example 2.
Calculating part 514 relatively, accept comfortable not pick-up unit 140 or not signal, when having no talent in the sensor zone, air-conditioning is carried out energy-conservation setting, when the people gets back to surveyed area, return original setting value, like this, automatically guarantee the Energy Saving Control of comfortableness.
Below, the action of above-mentioned electrical management device 30 is described.
Figure 10 is a process flow diagram, represents to compare in this example the treatment scheme of calculating part 514.
At first, relatively calculating part 514 receives from setting accumulative total electric power amount higher limit, the interlock that display device 500 sends here by lamp cord 200 and sets sign and do not setting sign (S1001) at interlock.When or not the interlock setting is masked as " 1 " time (S1002:Yes),, judge whether " in the chamber " (S1004) from or not being received in not at sensor signal (S1003) pick-up unit 140.
If be judged as in the chamber (S1004:Yes), and, will not be set at " 1 " at sign or not sensor signal is " 0 " time, air-conditioning in the number of chambers according to storing (S1009) as the air-conditioning control data.
On the other hand, if be judged as in the chamber and at or not be masked as " 1 " time (S1005:No), the air-conditioning setting data as air-conditioning control data and air-conditioning in the number of chambers according to storing (S1006, S1007).
In addition, if be judged as not when the chamber, relatively whether calculating part 514 analyzed or not the value of sign, when its value during for " 1 ", not changing to " 0 " (S1011) in the value that indicates, the energy-saving type air conditioner setting data as air-conditioning control data (S1012).
Then, relatively calculating part 514 is exported to remote signal efferent 120 to the value of air-conditioning control data, control air-conditioning 160 (S1013).
In addition, relatively calculating part 514 is analyzed the value that interlock is set sign, when its value is " 1 ", accept accumulative total electric power value (S1015) from accumulative total power measurement portion 111, when accumulative total electric power value has surpassed accumulative total electric power amount upper limit set value (S1016:Yes), stop to air-conditioning 160 power supplies (S1017, S1018).
Below, illustrate that " or not sensor signal " reaches the relation of " or not sign " and air conditioner energy saving control.Should " or not sign ", be used for keeping with some cycles (for example 1 second cycle) input or not the sign of last time importing duration of sensor signal.For example, be at present not in the chamber (promptly, be not " 0 "), and be the situation that (is " 1 ") in the chamber just now in value or not sign in the value of sensor signal, be to have become not in the chamber owing to the people goes out from the room, so, based on energy-saving type air conditioner setting data to air-conditioning, the control air-conditioning.So-called " based on the air-conditioning control of energy-saving type air conditioner setting data " for example is meant if be set at 26 ℃ when the chamber, should be that room temperature is set at 30 ℃ based on the air-conditioning control of energy-saving type air conditioner setting data then when refrigeration.In the time of these 30 ℃, if the people feels quite uncomfortable in indoor meeting, but for energy-conservation be effective design temperature, can realize not energy-conservation when indoor of people effectively.
On the other hand, be (promptly, not to be " 1 ") at present in sensor signal in the chamber, and be the situation that (promptly, be not masked as " 0 ") not in the chamber just now, be to become in the chamber owing in people's return to room, so, as air-conditioning in the number of chambers according in store setting, deliver to air-conditioning, can get back to the set condition when the chamber.Certainly, if, just needn't set change to air-conditioning in the chamber or when not changing in the chamber.
With above-mentioned example 2 similarly, even after once setting accumulative total electric power amount higher limit, also can make Energy Saving Control invalid by the interlock sign being set at " 0 " (not interlock).In addition, can be at any time 102 the zero setting signal be delivered to accumulative total power measurement portion 111, this accumulative total power value zero setting constantly from the configuration part.Therefore, before calculating part 114 actions relatively or the accumulative total power value utilize when having surpassed higher limit etc., be effectively.
As mentioned above, according to the electrical management device 30 of example 3, by with or not pick-up unit 140 or not the signal interlock, can be only automatically carry out the energy-conservation setting of air-conditioning during not in the chamber the people, so, can reduce user's uncomfortable property as far as possible, can realize high energy-conservation of convenience.
In addition, in this example, be comparison calculating part 114 at power measurement control device 110, the size of accumulative total electric power amount upper limit set value of setting by the configuration part 102 of setting display device 100 and the accumulative total electric power value measured by accumulative total power measurement portion 111 relatively.But, also can relatively not add up the electric power amount, compare but be converted into accumulating sum (electricity charge).At this moment, for the accumulative total electric power value of being measured by accumulative total power measurement portion 111 is converted into the amount of money, the electric power value with respect to the amount of money is set in advance in the power measurement control device 110 102 usefulness amount of money capping values from the configuration part.
In addition, in this example, power measurement control device 110, set display device 100, in the or not communication between the pick-up unit 140, be to utilize lamp cord.But,, also can adopt radio communication in order to carry out telecommunication.The invention effect
