Description

The present invention relates to a system for saving

  of energy, provided with artificial intelligence and which makes it possible to reduce electrical energy by disconnecting an AC power supply sent to a facsimile machine during a

waiting state.

  More particularly, the present invention relates to a device for achieving energy saving, provided with an artificial intelligence and such that the supply of alternating current energy is interrupted when a pulse signal or an impedance variation does not occur not, and in which the AC power supply is applied when a pulse signal or an impedance change occurs, which means that it is possible to execute a fax operation using the application automatic power supply to

  AC power to the fax machine.

  The system for saving energy from a conventional facsimile apparatus is as follows. First of all, under the effect of its full-wave rectification, an input power supply with alternating current (alternating voltage of 110 V or 220 V) is transformed into a direct current energy supply and the supply into direct current energy is converted to a standby power source by means

of constant tension.

  Then, even in the absence of a transmission or reception, the power source is always active, that is to say that while an energy saving is in progress, the power source standby is applied to a circuit to implement the standby mode or state as an operating power source, and thereby an energy saving mode is activated. When an entry is made using a key for a transmission or when an impulse signal for a reception arrives, the conventional system which saves energy goes from the standby state to the state d Use and Apply Power for Operation to All Parts of the Fax System

  to perform transmission or reception.

  While the conventional facsimile system as previously indicated achieves energy savings through the use of a standby power source in the power saving mode, it is impossible to achieve economy full of energy even in the energy saving mode since the operation of several circuits requires considerable electrical energy. The object of the present invention is to solve the drawback appearing in the case of operation.

  with energy saving of a known fax machine.

  The object of the invention is to provide an improved energy saving device, provided with an artificial intelligence, which disconnects the supply of alternating current energy before the production of a pulse signal or of a variation d impedance and which, when an impulse signal or an impedance change occurs, automatically applies an AC power supply to a facsimile system, which results in facsimile transmission becoming possible. More particularly, the object of the present invention is to provide an energy saving device, provided with artificial intelligence and which can achieve complete energy saving without

  no loss of electrical energy.

This part includes: - a reset part 91 constituted by a diode D8 and a transistor Q1 to bring the logic control part 80 back to the initial state, - a switching part 92 constituted by a transistor Q2 performing a switching for supplying or interrupting a power supply as a function of signals produced in said logic control part 80, and - a relay 93 for applying or interrupting an AC power supply to main parts as a function of the operation of a

  transistor Q2 in the switching part 92.

  Below, we will explain the operation of an energy-saving device, provided with artificial intelligence, according to the invention as indicated

  previously, with reference to Figure 2.

  First of all, the AC / DC conversion part 10 converts the AC power supply introduced via two terminals L, N into a DC power supply by means of rectification by the bridge. diodes D2 to D5. Then, the DC power supply obtained in this way is applied to a downstream terminal after having

  been smoothed in a C3 capacitor.

  A noise filtering part 20 having an inductance Li and a capacitor C4 suppresses the noises from the energy current power supply line smoothed by said capacitor C3, and the part 30 forming

  pulse duration modulation stage and attack stage

  that produces a signal to achieve pulse modulation

  in time, which allows control of the current sent

  to a first coil of a transformer T1.

  The transformer T1 transmits said power supply flowing in the first coil to a second coil, under the control of the part 30 forming pulse modulation stage in duration and driving stage. Only an alternation of the DC power supply transmitted to a second coil is rectified and smoothed in a part 40 for filtering the ripple of the direct current, comprising a diode Dl and a capacitor Ci. At this moment, a part 50 of current and voltage detection detects the output current of the filter section 40 of the ripple of the direct current using an optocoupler 51 and sends an interrupt to the port Pl of the part 30 forming the stage of pulse modulation in duration and stage of attack, depending on the

  whether an output current is detected or not. That is

  say that, in the case where a direct current power supply is delivered by said portion 40 for filtering the ripple of the direct current, the current flows to a photodiode PD1 and therefore a light is emitted. Then, a phototransistor PT1 is activated by the light emitted. Consequently, the phototransistor PT1 signals that the DC power supply is supplied to a downstream terminal, placing the state of the port P1 of the part 30 forming at the low level.

  pulse duration modulation stage and attack stage

  than. Under these conditions, only a constant voltage is delivered to a downstream terminal and an overvoltage is blocked by the Zener diode D6 connected to the lower end of the photodiode PD1. The next part, which is the high frequency filtering part 60, removes the component located in the high band by means of an inductor L2 and a capacitor C2. Then the DC power supply, in which the high band component is suppressed by the high frequency filtering part 60, is sent to the external part 70 for detecting a logic signal, to the logic control part 80 and to the part 90 for controlling the supply of output energy at a rear terminal of the device. In addition, the external part 70 for detecting a logic signal is connected to telephone lines and detects a pulse signal or an impedance variation condition. That is to say that, in the case where a pulse signal or an impedance variation does not appear, a photodiode PD2 goes to the blocked state and by

  therefore the PT2 phototransistor is also blocked.

  In this case, the logic control part 80, the port of which is connected to a capacitor C9, identifies the fact that a pulse signal does not appear since the input signal applied to said port TR is the level signal high, and keeps the signal low

output from port 0.

  In this way, when the output signal delivered by the port 0 of the logic control part 80 is a low level signal, the transistor Q2 of a switching part 92 located in the part 90 of control of the output power goes into blocked state. In accordance with the above, no current flows in the coil of a relay 93 and therefore a switch of the relay is connected to a contact 5 so as to deliver no AC power supply to a downstream terminal of this device. In other words, in the event that an impulse signal or an impedance variation does not appear, the AC power supply is not applied to the main system of the downstream terminal, so

  that we get an energy saving function.

  On the contrary, in the case where a pulse signal or an impedance variation appears, the power supply is applied to the photodiode PD2 of the external part 70 for detecting a logic signal,

  which has the effect of producing a light emission.

  In accordance with this, the phototransistor PT2 is activated and the high level voltage applied to the port is derived in the direction of ground, which has the effect that the TR port

is placed at the low level.

  Then, the logic control part 80 identifies this as an interrupt and the output signal from the port O is set high so as to supply a power supply since a

  impulse signal or a variation in impedance appears.

  The transistor Q2 of the switching part 92 located in the power supply part 90 is placed in the conductive state by said high level signal transmitted. When the transistor Q2 goes to the state * inverter, the DC power supply supplied by the high frequency filtering part 60 flows to a coil of the relay 93 so that the relay switch is switched to a contact 4. At this instant, the input terminals L and N of the alternating current power source are connected together, which has the effect that an alternating current energy at 60 Hz is applied to the terminal back of this device. In fact, when an impulse signal or a variation in impedance appears, the input power supply is applied to the main parts of a facsimile apparatus and therefore an operation of

fax is executed.

  Figure 3 appended to the drawings shows another embodiment of a part 90 for controlling the output power in accordance with this

invention.

  As shown in FIG. 3, a part 90 for controlling the output supply comprises: a first switching element Q3 which operates as a function of the signal delivered by the logic control part 80 and therefore produces a signal actuation of a first relay, which must be applied to a line L of the AC power supply, - a second switching element Q4, which operates as a function of the signal delivered by the logic control part 80 and thereby produces an actuation signal of a second relay, to be applied to a neutral line N of the AC power supply, and - of the first and second relays RY2, RY3 which are controlled respectively on the basis of the operation of the first and second switching elements so that two lines of the AC input power supply are connected to a facsimile apparatus and thereby a power supply energy consumption is applied to

the fax machine.

  Similarly, in another embodiment of the output power control part 90, which is constituted in the same manner as mentioned above, when a logic control part 80 interprets the fact that a pulse signal or a variation in impedance appears, based on the detection of telephone lines, the logic control part 80 delivers a high level signal at an output terminal X1. The high level signal delivered by the output terminal X1 is distributed by distribution resistors R11, R12, then is applied to a base of the first switching element Q3 in a state of high electrical potential. Consequently, the first switching element Q3 is placed in the conductive state by the high level signal. The first switching element Q3 being placed in the conductive state, the DC power supply supplied by the high frequency filtering part 60 is applied to a coil of a first relay RY2 and therefore activates the first relay RY2, and a line L of the power supply among the power supply lines to

  AC power is connected to a fax system.

  Then, the logic control part 80 delivers a high level signal via the output terminal X1 as indicated previously and also, at the end of a determined time interval (approximately 5 seconds) delivers a high level signal via the other output terminal X2. Such high level signals delivered are distributed by distribution resistors R13, R14, then are applied to a base of a second switching element Q4 in a state of high electrical potential. Consequently, under the effect of the high level signal, the second switching element Q4 is placed in the conducting state. The DC power supply supplied by the high frequency filtering part 60 is sent to a coil of a second relay RY3 via the second switching element Q4 placed in the conductive state, and therefore the second relay RY3 is activated and a neutral line N among the AC power supply lines is connected to a facsimile machine. Thereby, the AC power supply is sent to the facsimile system and therefore a facsimile operation is performed. When a facsimile operation is completed, the logic control part 80 immediately blocks or places the output signals of the two output terminals X1, X2 at a low level so as to interrupt the supply of AC power applied to the system. fax machine. Therefore we get an energy saving

  in the fax machine.

  In accordance with the invention as indicated above, the device achieving energy saving provided with artificial intelligence, according to the

  present invention makes it possible to save energy.

  electric since electric energy is not

  not wasted in the standby mode, due to the inter-

  interruption of the AC power supply to be applied to main parts of the facsimile system, at an input terminal, in the event that a pulse signal or a change in impedance

does not appear.

  The previous description is considered only

  as illustrative of the principles of the present invention.

  Therefore, those skilled in the art may consider realizing different embodiments of the present invention based on these principles, while

  remaining within the scope of the invention.
