Definitions
- the invention relates to an electrical functional unit and a tube monitor according to the features of the preamble of claim 1.
- Tube display devices convert energy into heat unused.
- tube screen devices with a color screen have a power loss of approximately 100 watts.
- an electrical functional unit e.g. a personal computer
- the tube screen devices then referred to here as monitors mostly run in continuous operation, although the mere usage time only makes up a fraction of the operating time.
- a device arrangement can be removed with Tion 1 a tube screen device with a Warte einsfunk ⁇ and the CRT display device for its operation grund ⁇ applied via line connections a Stand ⁇ ardschnittstelle with corresponding signals supplied 5 controller.
- the device arrangement comprises a signal evaluation circuit which, if the signals on the keyboard signal line do not change for a predetermined period of time, switches off the power supply to the tube monitor via a power supply interrupter switch.
- the tube screen device thus also assumes a similar state to an energy-saving state.
- the modules of the tube screen device are prematurely worn out due to increased on / off cycles due to the total shutdown of the power supply, thereby shortening the life of the device. So this is not a component-saving energy saving control. If the tube heating is also maintained, there is a risk of "cathode poisoning". 0
- the object of the invention is therefore to provide an electrical functional unit and a tube screen device of the type mentioned at the outset, in which there is the possibility of the control device controlling an energy-saving state of the tube screen device which is gentle on the components by reducing power or switching off, without this the use of the individual devices is limited to an arrangement in which both the control device can control the energy-saving state of the tube screen device and the tube screen device can be controlled with respect to an energy-saving state.
- the individual devices Since it is possible to transmit a message for the control of an energy-saving state of the tube screen device, which is independent of the function of the standard interface, the individual devices are not in each case on a correspondingly opposite device reliant.
- the basic functions of the individual devices are guaranteed regardless of their mutual training with regard to the possibility of controlling or executing an energy-saving state. If the devices are not designed in opposite directions, either the tube screen device cannot receive or use the message for controlling the energy-saving state, or the control device cannot send such a message.
- the advantage of the energy-saving state cannot be used in these cases, but the individual devices as such remain universally applicable.
- control device has a device for switching off the transmission of a message controlling the energy-saving state of the tube screen device, because then tube-screen devices without an energy-saving state or without a corresponding configuration for controlling the
- Energy-saving state can be operated safely and trouble-free.
- FIG. 7 shows a video signal evaluation circuit of a monitor according to FIG. 6.
- a standard interface SS consisting of three line connections, two of which are used for the transmission of synchronization signals Hsync, Vsync in the X and Y directions of the screen Monitor M and the third are responsible for the transmission of a video signal VS.
- any other standard interfaces are conceivable. For example, those for the operation of monitors with a color screen and analog input. In this case, the standard interface would have, for example, three line connections for each video signal of a given color. In those with a digital input, the number of video signal lines would correspond, for example, to the number of possible color / brightness levels of the image to be generated.
- FIG. 1 shows a control unit PC and a monitor M, which are connected to one another via the standard interface SS and an additional line connection ZV that is independent of the standard interface SS.
- Control of the energy saving state of the monitor Control of the energy saving state of the monitor.
- the relevant message in coded form from the control device PC to the monitor M can be transmitted on the line connection ZV independently of the standard interface SS.
- the monitor M switches to an energy-saving state after a predetermined period of time. This also applies to the figures described below.
- connection SSa consists of the line connections of the standard interface SS and an additional line connection directly assigned to these line connections, so that ultimately the only connection SSa results.
- extension line in the Verbin ⁇ represents the standard interface SS still • free communication path is available, which is used for the transmission of the message for controlling the state of the monitor M Energysparzu-.
- the message for controlling the energy-saving state of the monitor M is transmitted in coded form on the line connections of the standard interface SS, so that no further line connections are required apart from the line connections of the standard interface SS.
- the control device PC has a video encoder VC, which encodes the message and integrates it into the video signal.
- the message generation function should optionally be selectable by the user, since otherwise return lines may be visible when using third-party monitors. However, this effect can be reduced by choosing the level and the color in particular.
- the monitor M has a so-called "power stand-by" decoder PSB-DC, which filters out a message PSB which is decisive for controlling the energy-saving state from the transmitted signals.
- the PSB decoder PSB-DC can also be activated by completely or partially withdrawing the sync signals. It is advantageous, at least in this case, if the control unit PC has a device for switching off the function controlling the PSB decoder, which e.g. can be operated optionally by a user of the control device PC. This could be done, for example, using so-called setup menu switches.
- FIG. 4 shows a monitor M which is connected with its mains line NL to the control device PC, via which it is connected to a main power supply source.
- the power line NL similar to For example, in the case of child monitoring systems operated via the house network, a message for controlling the waiting function of the monitor M is transmitted.
- the control device PC has a filter device FE in the direction of the main power supply source, so that neighboring devices are not disturbed.
- the message which is decisive for the control of the energy-saving state is transmitted to the monitor M via a wireless transmission channel.
- a wireless transmission channel This may for example 'done like.' Infrared signals, ultrasonic signals or
- the message which is decisive for controlling the energy-saving state is transmitted via the video signal line VS.
- the monitor M has a video signal evaluation circuit in order to detect changes in the video signal.
- the monitor M is switched after expiry of a given time period vorgege- in the power saving state.
- Such a video signal evaluation circuit is outlined in FIG. It has a detector in the form of a low and downstream high pass TP, HP, which is followed by an evaluation circuit TR and this in turn is followed by a time delay circuit MK having a time constant tmin. At the output of the time delay circuit MK, for example, the negated message PSB for controlling the energy-saving state of the monitor M can be tapped.
