ELECTRONIC APPARATUS WITH MEANS FOR CONTROLLING THE POWER CONSUMPTION AND CORRESPONDING METHOD
The present invention pertains to an electronic apparatus, comprising a power supply unit, a screen and an electronic measurement device for measuring the consumed power on the primary side of said power supply unit.
Furthermore, the invention pertains to a method for controlling the power of an electronic apparatus and to a system of an electronic apparatus and a computer system.
Today nearly all kinds of electronic apparatuses for presenting motion pictures and images on a screen, such as computer monitors, TV sets or other display devices, are power-hungry as they provide a wide functionality and additional features for processing and enhancement of image data, for playback of audio data and for configuration purposes .
However, situations could arise in which the whole functionality and/or additional features are not necessarily needed. This could be the case if the user does not need special functions, for example supplementary audio functions for a computer monitor in an office environment. Another case is given by the fact that an additional function for enhancement of the luminance and brightness of a display could probably be neglected if the room or area where the apparatus is used is hardly illuminated.
Therefore, an electronic apparatus consumes much more power than necessary, if a user does not adapt the functions to the situation and the environment in which the apparatus is currently used. Furthermore, a user often does not have any motivation for reducing the consumed power or forgets to do so .
Therefore, it is an object of the present invention to provide an electronic apparatus, a method for controlling the power of an electronic apparatus and a system of an electronic apparatus and a computer system with enhanced power saving efficiency.
Pursuant to a first aspect of the present invention an electronic apparatus comprising a power supply unit, a screen, and an electronic measurement device for measuring the consumed power on the primary side of said power supply unit is provided for displaying the consumed power on said screen. This solution has the advantage that a user always knows the current power consumption level and therefore has a motivation for adapting and setting functions of the electronic apparatus in order to save power in a more efficient way than was possible up to now.
In a preferred embodiment the electronic apparatus comprises a device for generating an on-screen display, wherein said on-screen display is provided for displaying the consumed power. By this feature a user is given the possibility to access an on-screen menu for monitoring the actual consumed power level.
Furthermore, the electronic measurement device is preferably located in the power supply unit and a communication bus is
preferably provided, whereby the measurement device communicates with a main board of the electronic apparatus for sending and/or receiving data. Thus the consumed power on the primary side of the power supply unit is directly measured by said electronic measurement device, wherein data representative of the detected consumed power is transmitted to the main board of the electronic apparatus via the communication bus.
It is also possible that the electronic measurement device, besides means for the measurement of the consumed power, also comprises means for a temperature measurement. The information about the temperature level of the power supply unit can also be transmitted via communication bus to the main board of the electronic apparatus. In this manner the electronic measurement device detects current information about the energy level and the consumed power of the primary side of the power supply unit which allows the electronic apparatus to process and display this information on the screen. Regarding the information shown on the screen, a user always has knowledge of the current energy and consumption level of the electronic apparatus and can therefore adapt the functionality of the apparatus in order to efficiently save power .
In another embodiment the electronic apparatus comprises a power supply unit, a screen, an electronic measurement device for measuring the consumed power on the primary side of said power supply unit and a data communication interface for connecting said electronic apparatus to a computer system. The electronic apparatus is characterized in that it is designed for providing signal values of said measured consumed power at said data communication interface. Hence,
the electronic apparatus is prepared to transmit information about the consumed power to a computer system, which is able to interpret and process this information for re-sending it to the electronic apparatus. Then the electronic apparatus can display the processed and re-sent information about the measured consumed power level on its screen. Thus, in this embodiment it is not the electronic apparatus which processes its detected consumed power for displaying on the screen, but a computer system that is connected to the electronic apparatus via a communication interface.
In further preferred embodiments the electronic apparatus is either a computer monitor or a TV set.
Pursuant to a second aspect of the present invention, a method for controlling the power of an electronic apparatus is characterized by the following steps: Detecting the consumed power of said electronic apparatus by means of an electronic measurement device located in said electronic apparatus, processing signal values of the detected consumed power for providing a graphical representation of the consumed power, and displaying said graphical representation on a screen of the electronic apparatus. The mentioned method has the advantage that a user is always informed about the actual power consumption level of the electronic apparatus for identifying functions that are power-hungry and that can be neglected in order to save energy.
Preferably, the data representative of the detected consumed power is transmitted from the electronic apparatus to a computer system connected to the electronic apparatus by means of a data communication interface. The computer system performs the processing of the detected consumed power for
providing a graphical representation. Then this representation can be displayed on the screen of the electronic apparatus to inform a user about the current power consumption .
Furthermore, the consumed power of the electronic apparatus is processed by software in the computer system and can be transmitted to another computer system. This other computer system can, for example, be a server of an information technology (IT) department of a company or office which is then able to interpret the transmitted information and to control the computer system and finally the electronic apparatus to reduce the power consumption. This is for example beneficial in an office environment wherein several computer systems with computer monitors or other display devices are installed whereas it is suitable to limit all of the display devices in their power consumption.
This can be effected by an electronic apparatus according to the present invention which is able to detect its consumed power, to process and/or to transmit the data representative of the power consumption level for a graphical representation to a computer system that itself passes this information to another computer system or a server system for interpreting the consumed power and for limitation of the power consumption of the electronic apparatus. This is suitable if an electronic apparatus, for example a display device in the office environment, consumes much more energy than is necessary.
For limiting the consumed power at least one of the computer systems in the chain of signal propagation preferably generates a power saving command which is transmitted to the
electronic apparatus via a data communication interface and which influences the power consumption of said electronic apparatus. A power saving command could, for example, include a sequence for activating or inactivating additional features of the electronic apparatus or for changing settings such as the brightness or the luminance in order to reduce the consumed power.
A further aspect of the present invention pertains to a system of an electronic apparatus and at least one computer system, wherein the electronic apparatus and the at least one computer system are designed to perform the above-mentioned method for controlling the power of the electronic apparatus.
Further features and advantages of the present invention are disclosed in the dependent claims and in the description of the drawings .
The invention is now described in more detail based on embodiments depicted in several drawings. In the figures,
Figure 1 shows an electronic apparatus according to the present invention,
Figure 2 shows a schematic diagram of an electronic apparatus providing an on-screen display,
Figure 3 shows a schematic diagram of an electronic apparatus providing an on-screen display and being connected to a computer system, and
Figure 4 shows the schematic diagram of a communication process between a server and several display devices according to the present invention.
Referring to Figure 1, an embodiment of an electronic apparatus 1 is shown which comprises a power line 2 for connecting the electronic apparatus 1 to a primary electric power source and a screen 3 for displaying video information and/or an on-screen display (OSD) 6. The electronic apparatus 1 further comprises several control buttons 4 and a light- emitting diode (LED) 5 for controlling the electronic apparatus 1 and for providing status information about the operating state of the electronic apparatus 1. Such operating states can for example be a hard-off state where the electronic apparatus is completely turned off, a stand-by state where the electronic apparatus 1 is in a sleeping mode with the screen 3 turned off and an on state where the electronic apparatus 1 is completely turned on with the screen 3 being illuminated and providing some video information. In the embodiment shown in Figure 1 the electronic apparatus is a computer monitor or a TV set. However, the electronic apparatus 1 could also be any other display device.
The on-screen display (OSD) 6 provides control options for the configuration of the electronic apparatus 1, as there are for example a brightness, luminance and/or RGB colour control, an audio control or some control of the position and the angle as well as the horizontal and vertical synchronization (H-Sync, V-Sync) of the displayed information on the screen 3. Furthermore, the OSD 6 contains an option for monitoring a detected level of consumed power of the electronic apparatus 1. This informs a user about the actual
power consumption and gives the possibility to adapt several additional features of the electronic apparatus 1 to the actual operating situation or a special environment in which the electronic apparatus 1 is being operated. For example, a user can lower the contrast if the electronic apparatus 1 is used in an environment which is hardly illuminated. With this measure a user can reduce the power consumption of the electronic apparatus 1 by controlling the power consumption level shown on the screen 3 through the OSD 6.
This solution is also applicable to an economy mode in which a part or all of the supplementary functions are automatically driven in a power saving mode. Since the economy mode can be activated, for example, by pushing a special button placed at the system housing or on a remote control or the like, it can be utilized in an efficient manner for reducing the power consumption of the electronic apparatus 1. By simply activating the economy mode, the user can control additional functions in dependence on the actual power consumption level that is shown on the screen 3 of the electronic apparatus 1.
The display device 1 shown in Figure 1 can also comprise a data communication interface (not shown in Figure 1) such as Video Graphics Array (VGA), Digital Visual Interface (DVI), High Definition Multimedia Interface (HDMI), Display Data Channel (DDC) or the like for the connection to a computer system which allows to exchange video data or other information between the electronic apparatus 1 and the computer system.
Figure 2 shows a schematic block diagram of an electronic apparatus 1 according to Figure 1 wherein the internal
electric components of the electronic apparatus 1 are shown in more detail. The electronic apparatus 1 comprises a power line 2 for connecting the electronic apparatus 1 to a primary power source to supply the electronic apparatus 1 with electric energy. Furthermore, the electronic apparatus 1 comprises a power supply unit 7 which transforms a primary alternative current (AC) into a direct current (DC) on the secondary side of the power supply unit 7. An electronic measurement device 8 is located in the power supply unit 7 for measuring the consumed power, which is drawn from the primary power source by the electronic apparatus 1. The device 8 preferably captures real time values of the supplied voltage and current on the primary side and calculates after filtering an instantaneous mean power level by firstly multiplying the detected voltage and current signal values and by secondly applying some averaging procedures to these processed signals to calculate the consumed mean power level. The averaging can be effected, for example, by applying some root-mean-square (RMS) procedures.
After all, the detected data representative of the power consumption level can be transmitted from the electronic measurement device 8 to a main board 9 of the electronic apparatus 1 by means of a communication bus 10. Hence, the main board 9 can interpret and process the acquired information about the consumed power wherein the main board 9 is able to create an on-screen display 6 for monitoring the consumed power. To effect this, an on-screen display 6 contains, among several sub-categories 11a to Hd, a power consumption monitor 12 which shows the actual power consumption level of the electronic apparatus 1. The power consumption monitor 12 can for example provide a relational value between a minimum value and a predetermined maximum
value wherein the relational value is a percentage of the maximum value of the power consumption. Within the embodiment according to Figure 2 an electronic apparatus 1 is therefore able to detect and provide the actual consumed power level to a user who can adapt the functionality of the electronic apparatus 1 to reduce the power consumption of the electronic apparatus 1 in an efficient manner.
Referring now to Figure 3, an electronic apparatus 1 with components according to Figure 2 and a first computer system 13a are schematically depicted. As described in Figure 2 the electronic apparatus is able to detect its actual consumed power via electronic measurement device 8 located on the power supply unit 7 and is able to communicate this information to a main board 9 via communication bus 10. The embodiment shown in Figure 3 provides the following options: In a first option the main board 9 effects the monitoring of the consumed power level through an on-screen display 6 as described in Figure 2. In a second option the detected consumed power level is transmitted from the main board 9 to the first computer system 13a by means of a data communication interface 14. The data communication interface 14 preferably relates to a display data channel (DDC) and therein preferably to one of the DDC2B, DDC2B+, DDC2AB or DDC/CI standards that allow a bidirectional data exchange between the main board 9 and the first computer system 13a via the Inter-Integrated Circuit (I2C) bus standard. Therefore, such a DDC interface 14 gives the possibility to the main board 9 to transmit the detected consumed power level to the computer system 13a and in particular to a video card incorporated on a main board of the computer system 13a.
The computer system 13a then processes the information to convert it into a graphical representation and sends this representation back to the main board 9 over the interface 14. Hence, the main board 9 of the electronic apparatus can prepare the processed graphical representation sent by the computer system 13a for displaying on the screen 3 of the electronic apparatus 1 and especially in the OSD 6 according to the above-mentioned method. It is also possible that the first computer system 13a stores or passes the collected information on the consumed power level to another computer system (not shown in Figure 3) whereas the other computer system can re-process the given information.
Referring now to Figure 4, several electronic apparatuses 1 are shown which are communicatively connected to a second computer system 13b that belongs to a server system of an information technology (IT) department. It should be noted that each of the electronic apparatuses 1 is connected to its respective first computer system 13a which is, however, not shown in Figure 4 for reasons of simplicity. The IT department can receive information about the operating state and/or the consumed power from all of the depicted electronic apparatuses 1 and can transmit control data for setting an operational mode to the apparatuses 1 via a communication channel 15, which contains a network connection and a data communication interface 14 as described in Figure 3. Hence, the measured consumed power in one electronic apparatus 1 can be sent to its respective first computer system 13a and then is passed to the computer system 13b whereas the computer system 13b effects the processing of a graphical representation of the consumed power level. This can for example be achieved by using suitable software solutions that are part of an operating system installed on the computer
system 13b. The graphical representation is then sent to the electronic apparatus 1 via the communication channel 15 that is capable of a bi-directional transmission. These communication activities are depicted as bi-directional arrows between the computer system 13b and each of the electronic apparatus 1.
Beyond, the computer system 13b is able to generate a power saving command that is transmitted to one or all of the electronic apparatuses 1 via channel 15. This process is indicated by dashed unidirectional arrows pointing from the computer system 13b to each of the electronic apparatuses 1. Hence, the computer system 13b of the IT department controls each of the electronic apparatuses 1 to reduce its power consumption and to adapt additional features in an efficient manner .
Therefore, the embodiment according to Figure 4 allows the IT department to collect information about the power consumption of each of the display devices 1 in a special environment. The IT department either can create a graphical representation of the consumed power for displaying on the display devices 1 to inform the user of the display device 1 or can process the information about the consumed power and can generate a control sequence to command each of the display devices 1 to limit its power consumption in a suitable manner.
