1 is a schematic block diagram functionally configuring a standby power cut-off switch according to the present invention.

Referring to FIG. 1, the standby power cutoff switch 100 according to the present invention includes a power measuring means 110 for measuring power, a switching means 120 for switching on and off power supplied to a load, and standby power. A reference value storage means 130 for storing a reference value of the microcomputer 140 for controlling on / off switching of power by comparing the measured power with a stored reference value, and allowing a user to operate the microcomputer 140, User control means 150 for operating the switching means 120 and setting a reference value of standby power; forced control means 160 for controlling the switching means 120 by the user in case of failure or malfunction; The main display means 170, the main display means 170 for displaying the on-off switching state of the switching means 120, the normal driving power supply to the load 10, the standby power supply and whether the standby power is cut off; To the display means 175 and the microcomputer 140 It comprises a power supply means 180 for supplying the same power.

First, the power measuring unit 110 measures the magnitude of an external commercial power supply, such as an alternating current, supplied to the load 10, that is, various electric and electronic products, and transmits the magnitude to the microcomputer 140.

Next, the switching means 120 switches on and off the external commercial power supplied to the load 10. That is, the switching means 120 is to cut off or maintain the external commercial power supplied to the load 10, triac (silicone controlled rectifier (SCR) or relay relay capable of two-way control) ) Can be implemented.

Next, the reference value storing means 130 is a memory for storing the reference value of standby power. Here, the standby power means power consumed by the electronic circuit included in the load 10 even when the load 10 is suspended. On the other hand, the reference value of the standby power stored in the reference value storage means 130 may be set and stored by the microcomputer 140 to be described later, or directly set by the user by the user control means 150 to be described later Can be stored. That is, the microcomputer 140 compares and determines the power respectively measured by the power measuring means 110 according to the use time of the load and the use stop time, and is stored in the reference value storage means 130 as a reference value of standby power or the load. The user can directly store and set the power supplied to the load 10 as the reference value of the standby power in the reference value storage unit 130 through the user control means 150 to be described later when the use of 10 stops. Accordingly, by allowing the user to arbitrarily set the reference value of the standby power or to be performed by the microcomputer 140, all users who are familiar or not familiar with how to use the standby power cutoff switch 100 can conveniently use the standby power cutoff switch 100. Can be.

On the other hand, the reference value storing means 130 is implemented as a nonvolatile memory to store the reference value of the standby power and the on-off switching state of the switching means so that the microcomputer 140 stores the reference value even if the microcomputer 140 is reset. The reference value of the standby power stored in the means 130 and the on-off switching state of the switching means may be used to maintain the state before reset.

Next, the microcontrol unit (MCU) 140 compares the power measured by the power measuring unit 110 with the reference value of the standby power stored in the reference value storing unit 130 to the load 10. When the power supplied is less than or equal to the standby power of the reference value, the switching means 120 is controlled to be switched off to cut off the external commercial power supplied to the load 10. That is, by the control of the switching means 120 of the microcomputer 140 described above, the standby power supplied to the load 10 is cut off when the electrical or electronic product is not in use or suspended, which is unnecessary by the conventional standby power. By minimizing the amount of power consumed, energy can be saved and environmental pollution from additional power generation can be reduced.

Next, the user control means 150 allows the user to directly operate the microcomputer 140, allows the user to directly operate the switching means 120, and allows the user to directly set the reference value of standby power. In detail, the control means 150 for the user may select whether the user directly performs the above-described operation of the microcomputer 140, that is, the manual and automatic control of the microcomputer 140, and the user selects the switching means 120. Direct on-off switching is controlled, and the current power measured by the power measuring means 110 is set to a reference value of standby power stored in the reference value storing means 130. On the other hand, the user control means 150 may be implemented as a touch (touch) or a contact (tact) switch.

Next, the forced control means 160, even when the power control means 110, the switching means 120, the reference value storage means 130, the microcomputer 140 or the control means for the user 150, malfunctions, The user directly controls the switching means 120 to cut off standby power consumed by the load 10 when the load 10 is not in use or stopped. For example, the forced control means 160 is a means for the user to directly control the switching means 120 when the control element constituting the standby power cut-off switch 100 fails or normal operation is difficult. That is, the microcomputer 140 is electronicized to perform the above-described operation, and the entire process is implemented by a complex program. As is well known, the microcomputer 140 has a higher probability of failure or malfunction than the mechanical control means. In case of malfunction or malfunction, the switching means 120 cannot be controlled, resulting in inconvenience. Therefore, since the user can directly control the switching means 120 by the forced control means 160, it is possible to minimize the inconvenience described above.

Next, the main display means 170 visually displays the on-off switching state of the switching means 120 and whether the normal driving power supply, the standby power supply, and the standby power are cut off to the load 10. For example, the main display means 170 is implemented as an LED or LCD, so that when the switching means 120 is turned on and the external commercial power source, that is, the normal driving power is supplied to the load 10 during the normal operation of the load 10, When the standby power is supplied to the load 10 when the load 10 is not in use or stopped, it is visually blinked, and the switching means 120 is turned off to block the standby power supplied to the load 10. Can be turned off visually. On the other hand, the main display means 170 may accurately display the current power measured by the power measuring means 110 in Arabic numerals.

Next, the auxiliary display means 175 displays whether the microcomputer is automatic and manual, and whether the reference value of standby power is stored. For example, the auxiliary display means 175 visually displays whether the user directly performs the operation of the microcomputer 140 selected by the user control means 150, that is, whether it is manual or automatic, and controls the user. It is visually displayed whether or not the reference value of the standby power is directly stored in the reference value storage means 130 by the 150.

Next, the power supply unit 180 supplies the driving power of the microcomputer 140, and converts commercial power into the microcomputer 140 using a switching mode power supply (SMPS) or a transformer. It can be converted to a driving power source, or an external commercial power source independent of the commercial power source can be used.

2A to 2D, the standby power cutoff operation of the standby power cutoff switch according to the present invention will be described in detail as follows.

FIG. 2A is an example of a timing diagram for implementing control means for a user of the standby power cutoff switch of FIG. 1.

Referring to FIG. 2A, as described above, the control means for the user may select whether the user directly performs the operation of the microcomputer, the user may directly control the on / off switching of the switching means, and the reference value storage means. Set the reference value of standby power stored in the.

That is, the above-described operation of the control means for the user may be set differently according to the duration of time when the user presses the control means for the user implemented as a touch or contact switch. For example, when the user presses the control means for the user for a time of t1, for example, 1 second or less, the user controls the on / off switching of the switching means, and presses the control means for the user for a time of t2, for example, 3 to 4 seconds. The operation of the microcomputer is repeatedly switched automatically and manually so that the user can select whether the user directly performs the microcomputer operation, and when the user's control means is pressed for a time of t3, for example, 6 seconds or more, the current is measured by the power measuring means. The measured power is controlled to be stored in the reference value storing means as a reference value of standby power. Here, t1 is a value smaller than t2, and t2 is a value smaller than t3.

On the other hand, as described above, the above-described operation may be implemented according to the duration of the pressing time of one user control means, the above-described operation by the user control means composed of at least two touch or contact switches, namely On-off switching of the switching means, automatic and manual repetition of the microcomputer, and storage of reference values of standby power may be implemented separately. Here, all the timing diagrams shown in FIG. 2A indicate in time the duration in which the user presses the control means for the user.

FIG. 2B illustrates an example of controlling the switching means and the main display means according to the power measured by the power measuring means of the standby power cutoff switch of FIG. 1.

Referring to FIG. 2B, an example in which the microcomputer controls the switching means and the main display means in accordance with the power measured by the power measuring means, is performed during normal operation of the load, that is, before entering the standby power mode (before t1). The means and the main display means are turned on, respectively, to indicate that the electrical and electronic products are in use, and when the standby power mode is entered (t1 to t2), that is, the power measured by the power measuring means is the reference value of the standby power stored in the reference value storing means. In the following cases, the main display means blinks to inform the user visually that standby power is being supplied to the load. Thereafter, after a predetermined duration (t2-t1) elapses after entering the standby power mode, the microcomputer turns off the switching means and the main display means to cut off the standby power supplied to the load. As described above, it is possible to provide convenience to the user by visually informing the user whether the standby power is supplied to the load by the main display means and whether the switching means is switched on or off. Here, the standby power mode refers to a case in which the power measured by the power measuring means is equal to or less than a reference value of standby power stored in the reference value storing means, and in fact, refers to a case in which the electric or electronic product is not in use or in use. On the other hand, the timing diagram of the upper end shown in Figure 2b relatively shows the magnitude of the power measured by the power control means, the middle timing diagram shows the on-off state of the switching means. The timing diagram at the bottom shows the on-off state of the main display means.

FIG. 2C illustrates an example of setting the power measured by the power measuring means by the user control means of the standby power cutoff switch of FIG. 1 to a reference value of the standby power.

Referring to FIG. 2C, when the user control means 150 is pressed for a predetermined time t2 between the standby power mode entry t1, the current power, that is, the power measured by the power measuring means, stands by in the reference value storing means. It is stored as a reference value of power.

FIG. 2D is an example of a timing diagram for driving forced control means of the standby power cutoff switch of FIG. 1.

Referring to FIG. 2D, in the case where the control of the switching means by the microcomputer is impossible when the microcomputer fails or malfunctions, the user may forcibly turn on or off the switching means through the forced control means. The switching means can be forced on and off by means of an element, for example a flip-flop or toggle switch.

As shown in FIG. 2D, when the forced control means is implemented as a toggle switch, when the user toggles the forced control means 160, the switching means 120 is turned on, and conversely, the user is forced to the forced control means 160. Toggling off the switching means 120 is off. That is, the switching means 120 may be directly on / off switched by the forced control means 160 to perform normal power supply or standby power cutoff to the load even when the microcomputer fails or malfunctions. On the other hand, Figure 2d shows an example of implementing a forced control means by a toggle switch, the same result and effect can be obtained even if implemented by a flip-flop, a state-maintaining device.

On the other hand, by implementing the standby power cut-off switch according to the present invention in combination with the outlet, it can provide convenience to the user in actual use. Here, a load, that is, an electrical and electronic product used by the user is electrically connected to the outlet, and power is supplied to the electrical and electronic product.

FIG. 3A is a first implementation diagram of the standby power disconnect switch of FIG. 1, and FIG. 3B is a second implementation diagram of the standby power shutdown switch of FIG. 1.

In addition, referring to an area marked as standby power shown in the lower part of FIG. 3A, a specific operation will be described. When the main display means 170 is in an on state, a switching means (not shown) is turned on, and It is an indication that the electrically connected electrical and electronic products are operating normally. If the main display means 170 is in a blinking state, it is an indication that standby power is being supplied when the electrical and electronic products are not in use or stopped. An off state 170 indicates that the switching means is off and the standby power supply to the electrical and electronic products is being cut off. In addition, the auxiliary display means 175 visually displays whether the user directly performs the operation of the microcomputer selected by the user control means 150, that is, whether it is manual or automatic, and displays the user control means 150 on the user. Visually indicating whether the reference value of standby power is directly stored in the reference value storage means.

Meanwhile, as implemented in FIGS. 3A and 3B, the standby power cutoff switch may be configured as a switch structure that is easily accessible to the user, thereby actively inducing the user to maximize the standby power cutoff effect.

Therefore, according to the standby power cut-off switch having the configuration as described above, by determining the standby power state for the electrical and electronic products using the commercial power source, in the standby power state, by completely shutting off the power supplied to the electrical and electronic products, Energy can be saved by preventing unnecessary power consumption by standby power, and environmental pollution due to the production of additional power of standby power can be reduced. In addition, even when the standby power cut-off control is impossible due to a failure or malfunction of the electronic switching means, the user can forcibly control the switching means, thereby greatly improving user convenience, and setting the reference value of the standby power arbitrarily by the user. By automatically setting by so that all users who are not familiar or familiar with how to use conveniently can use it conveniently, it can induce user's use and provide convenience to the user to maximize the effect of blocking standby power.
