Fig. 1 diagrammatically illustrates the block diagram 100 being suitable to the exemplary context of use for realizing embodiment of the present invention.As
Shown in Fig. 1, ammeter 110 is connected to transmission line of electricity, and in measuring such as one family, the total energy of each electronic equipment disappears
Consumption.Electronic equipment 1 120, electronic equipment 2 122 ..., electronic equipment N 124 are connected to ammeter via transmission line of electricity respectively
110, and from transmission line of electricity to these power electronic equipment.In the environment, ammeter 110 can only measure each electronic equipment
The sum of energy expenditure, and the energy expenditure of independent each electronic equipment can not be measured.
Fig. 2 A and Fig. 2 B diagrammatically illustrate respectively according to different solutions, disappear for measuring the energy of electronic equipment
Organization Chart 200A and 200B of the technical scheme of consumption.
In the technical scheme shown in Fig. 2 A, for independent measurement each electronic equipment 1220A, electronic equipment 2
222A ..., the energy expenditure of electronic equipment N 224A, can connect ammeter 1 230A, ammeter at each electronic equipment respectively
2 232A ..., ammeter 3234A.It should be noted that, ammeter 1 230A in this embodiment, ammeter 2 232A ..., ammeter 3
234A is analogous to measure the ammeter of energy expenditure currently for each family, and this ammeter structure is complicated and also can take certain
Space.In this way, although the energy expenditure of each electronic equipment can be measured respectively, but dispose at each electronic equipment
Ammeter is worthless technical scheme.On the one hand being, ammeter belongs to precision instrument and relatively costly；Further aspect is that,
User the supply socket on wall may be attached the supply socket of " one-to-many " and connect multiple electronic equipment, so electricity
The quantity of subset is uncertain thus is difficult to.
It is used for measuring energy expenditure it addition, the production firm of some electronic equipment is integrated with " ammeter " in the electronic device.
But, the standard that different production firms follow is different, how to read each from these from the electronic equipment of different production firms
Energy expenditure be the work wasted time and energy.
In the technical scheme shown in Fig. 2 B, set up WLAN (such as, by the technology such as zigbee or bluetooth),
And measure the energy of each electronic equipment (such as, electronic equipment 1 220B, electronic equipment 2 222B ..., electronic equipment N 224B)
Amount consumes, and then utilizes corresponding wireless module (such as, wireless module 1 230B, wireless module 2 232B ..., wireless module
N 234B) to transmit the data about energy expenditure to ammeter 210B by this WLAN.Owing to WLAN needs
Special equipment support also needs professional to safeguard, thus this technical scheme is difficult to be generalized in average family use.
