Description

Power-saving power supply unit {POWER REDUCTION POWER SUPPLY APPARATUS}

One embodiment of the present invention relates to a power-saving power supply device, and more particularly, to a power-saving power supply device that can supply power to a load by using a detection result and a time schedule of whether a person is occupied.

As part of low carbon green growth being promoted worldwide, the power sector is encouraged to save energy through automatic monitoring and control based on time and space conditions.

As part of energy saving, indoor lamps installed in various houses, government offices, and public facilities, street lamps installed near roads, or outdoor lamps installed in residential areas, parks, etc. may be appropriately selected depending on whether people are present, sunrise time, and weather conditions. You need to turn it off. However, since it is very inefficient to open and close such indoor and outdoor lamps manually by manual operation, an opening and closing circuit for controlling the photoelectric sensor (CDS) connected to one lamp is usually used.

However, the conventional indoor and outdoor lamps have a semiconductor device such as a relay and a timer, and the operation time can be limited, but the operation time is limited to approximately 20 seconds, and also the operation of a light that requires low power or high power. There was a problem that it is difficult to save power substantially because it is difficult to supply power to fit.

In addition, this problem is present not only indoor and outdoor lamps, but also other electrical devices that require low power or high power.

1 to 2B, the power saving type power supply apparatus according to the present invention includes a main controller 20, a sensor unit 10, a first power supply unit 30, and a second power supply unit 40.

The sensor unit 10 is connected to the main controller 20 to detect the movement of the object and transmit the detection result to the main controller 20. In addition, the sensor unit 10 has a time schedule for the sensing operation is set in advance by the main controller 20. The sensor unit 10 may be an infrared sensor that detects a movement of a person or an object. However, the present invention is not limited to the type of sensor constituting the sensor unit 10, and other types of sensors capable of detecting the movement of a person or an object are also applicable.

The main controller 20 includes a plurality of channels for controlling the loads 50 to be powered, and sets a time schedule for operation of at least one of the plurality of channels. Outputs a control signal.

The main controller 20 is a RISC processor (Risk Instruction Set Compute Processor), the sensor unit 10, the first power supply unit 30 and the second power supply unit 40 through a plurality of channels using the I / O port. It can be connected to the control signal for each operation to generate and output to each. In addition, the main controller 20 is programmed and preset in advance with the types of loads 50 supplied with the primary power and the secondary power through the first power supply 30 and the second power supply 40.

One side of the main controller 20 may be connected to at least one switching element 25, and may control the operation of the loads 50 by controlling the operation of the switching element 25. To this end, the main controller 20 sets a time schedule for the sensing operation of the sensor unit 10 in advance. Preferably, the time schedule may be set at one of 30 minutes, 45 minutes, and 60 minutes. For example, in the state where the main controller 20 is set to detect the movement or loss of the object through the sensor unit 10 at an interval of 30 minutes, the movement or loss of the object is detected through the sensor unit 10. If detected, the switching element 25 is operated to continuously supply power to the loads 50. However, the main controller 20 does not supply power to the load at the time after 30 minutes, when the movement or loss of the object is not detected by the sensor unit every 30 minutes. In other words, when the main controller 20 sets the time schedule for the operation of the sensor unit 60 to 60 minutes, the sensor unit 60 first detects the motion of the object or the loss of a person for 60 minutes. Therefore, the movement of the object or the state of human occupancy is detected every 60 minutes. Therefore, when it is not detected that the movement of the object or the person in the room according to the time schedule is not recognized for 60 minutes, after 60 minutes the power to the load is cut off and automatically turned off.

In addition, when the lighting device of the loads 50 is included in the second load 52, the control signal may include an illumination signal set for each magnitude of intensity, such as weak, medium, steel. At this time, when the second load 52 is a lighting device, it is preferable that a lighting device having a power amount of approximately 300W is applied.

In addition, at least one amplification element between the main controller 20 and the sensor unit 10 to amplify a signal sensed by the sensor unit 10 to a port of the main controller 20 to a predetermined size. 15, that is, OP-AMPs may be connected. The input terminal and the output terminal of the amplifying elements 15 may be connected to a plurality of electronic elements such as a resistance element and a capacitor element to implement each operation.

The first power supply 30 is connected to the main controller 20, when the movement of the object is not detected by the sensor unit 10, receives the first control signal output from the main controller 20, The primary power is supplied to the at least one first load 51 requiring the small power among the loads 50. That is, the first power supply unit 30 supplies commercial power supplied from the outside to the first load 51 side, and receives the first control signal output from the main controller 20 together with the first control signal. One load 51 can be operated. In order to implement such an operation, the first power supply unit 30 may include a plurality of electronic devices, such as a plurality of resistors, capacitors, and diodes, for signal processing such as rectification or amplification of the first control signal.

In addition, a branch such as a refrigerator, a washing machine, and the like, which are separately branched to an output terminal of the first power supply unit 30, receive power from the main controller 20 regardless of the detection result of the sensor unit 10 of the loads 50. The third power supply unit 35 may further include a third power supply unit 35 to supply the primary power (that is, the regular power 220V) to the load 53.

The second power supply unit 40 is connected to the main controller 20, when the movement of the object is detected by the sensor unit 10, receives the second control signal output from the main controller 20, and At least one second load 52 that requires relatively high power compared to the first load 51 of the loads 50 through the relay 41 and the current amplifier 42 switched in accordance with the two control signals Supply secondary power. The relay 41 is a switching element that is turned on or off according to the result of detecting the movement of the object by the sensor unit 10. When the movement of the object is not detected by the sensor unit 10, the relay 41 is turned off. If detected, the signal is turned on to supply the control signal from the main controller 20 and the primary power to the current amplifier 42. The current amplifier 42 is a magnet (M / G) having an induction coil therein, receives a primary power source, that is, an output current from the relay 41, and raises (ie, amplifies) the second current. The load 52 can be supplied. Accordingly, the second load 52 is operated by being supplied with the output current raised from the current amplifier 42, that is, the secondary power. For example, when the first load 51 is a small power load such as sensors requiring a capacity of 200 W, the first load 51 is supplied with a primary power of 220 V (ie, a constant incoming power) for its operation. When the second load 52 is a load requiring a capacity of 5 KW, the second power 52 receives a secondary power (ie, a control power) of 220 V and 4 KW for its operation. In this case, the current amplification of the second power supply 40 is performed. The unit 42 may amplify the output current of the relay 41 to the magnitude of the current corresponding to the power of 4 KW.

The main controller 20, the first power supply unit 30, and the second power supply unit 40 may be provided in the distribution box 100. That is, as shown in FIG. 3, the main controller 20, the first power supply unit 30, and the second power supply unit 40 may be provided as one power supply unit 400 in the distribution box 100, respectively. The electronic device may be connected to the external / internal buildings and the sensor unit 10 through the terminal terminal 200 to supply power to the electrical devices based on the detection result of the sensor unit 10. The distribution box 100 is installed for each unit in a building such as an apartment, a villa, a detached house, a public building, an officetel, etc., and receives the main power (that is, commercial power) supplied from the outside to provide external / internal lighting products, Electrical supplies such as computers, air conditioners and washing machines, that is, loads 50 are distributed and supplied to a plurality of channels. In addition, the distribution box 100 may be provided with a circuit breaker 300 to cut off the power supply when a short circuit or overload occurs, thereby preventing fire or breakage of the electrical load. Each of the plurality of channels may be designed as a single-phase two-wire or R, S, T three-phase four-wire type, but the present invention is not limited thereto.

Although not shown, a surface protection layer may be formed on the top surface of the main controller 20 to protect the surface of the main controller 20. More specifically, the surface protective layer comprises a polypropylene resin and a high density polyethylene resin, the high density polyethylene resin, the melt index is within the range of 0.5 ~ 5.0g / 10 minutes (ASTM D1238), the density is 0.940 g / cm 3 or more and less than 0.970 g / cm 3, molecular weight distribution is 10 or less, the content may be 5 to 20% by weight.

The high-density polyethylene resin preferably has a melt index of 0.5 to 5.0 g / 10 min. If less than 0.5 g / 10 minutes, the miscibility of the polypropylene and the high-density polyethylene resin is lowered, a large amount of fish eye is generated, and when the amount exceeds 5.0 g / 10 minutes, roll unwinding property does not improve during manufacturing.

It is preferable that the density of the said high density polyethylene resin is 0.940g / cm <3> or more and less than 0.970g / cm <3>. If the thickness is less than 0.940g / cm3, the stiffness of the film is low to decrease the adhesive strength, and if it is more than 0.970g / cm3, the stiffness of the film is large and the adhesive strength increases, thereby damaging the surface to be protected.

It is preferable that the molecular weight distribution of the said high density polyethylene resin is 10 or less. If it exceeds 10, a large amount of fish eyes may occur.

The high density polyethylene resin may be included in 5 to 20% by weight based on 100% by weight of the polyolefin resin composition. When the content of the high-density polyethylene resin is less than 5% by weight, the degree of improvement in roll loosening is insufficient, and when the content of the high-density polyethylene resin is more than 20% by weight, a large amount of fish eyes may be generated or the appearance of the film may be poor.

The polypropylene resin may comprise an ethylene propylene block copolymer in which polypropylene and ethylene propylene rubber are polymerized stepwise in the reactor. When the polypropylene resin contains an ethylene propylene block copolymer, the average surface roughness of the film is further increased, and as a result, the roll releasing property can be improved.

The content of the ethylene-propylene copolymerized portion in the polypropylene resin is preferably within a range of 10 to 20% by weight. If it is less than 10% by weight, the loosening property is inferior, and if it exceeds 20% by weight, a large amount of fisheye may occur.

The intrinsic viscosity of the solvent extract (solvent xylene) of the ethylene propylene rubber is preferably in the range of 2.5 to 4.0 dl / g. If it is less than 2.5dl / g, the loosening property is inferior, and if it exceeds 4.0dl / g, a large amount of fisheye may occur.

According to the present invention, the surface protection layer configured as described above may be attached on the surface of the main controller 20 to protect the surface of the main controller 20 from external temperature, humidity, and impact, and further, the wiring around the main controller 20. It is possible to improve the insulation effect between the two and a plurality of electronic devices.

At this time, it is preferable that the thickness of the said surface protection layer is a coextrusion multilayer film which is 5-50 micrometers. If the thickness is less than 5㎛ annealed inferiority, if it exceeds 50㎛ may increase the adhesive strength significantly damage the surface to be protected. Moreover, it is preferable that surface roughness Ra of the said surface protection layer is 0.5 micrometer = Ra = 1.5 micrometer. If the surface roughness is less than 0.5㎛, the unwinding property of the film during adhesion and more than 1.5㎛ when the film appearance is not good and may damage the surface to be protected.

According to the power-saving power supply apparatus according to the present invention configured as described above, by detecting the presence of a person through the sensor unit 10, the time schedule for the operation is transmitted to the main controller 20, the main controller 20 Since the power supply to the load side is controlled based on the detection result, the power supplied to the load can be saved. In addition, according to the present invention, when a person is not occupied, the power supply to the load is cut off, thereby reducing power and improving electrical safety. In addition, according to the present invention, since the power supplies having different sizes are supplied to the load according to the types of loads requiring small power or large power, it is possible to improve the operational stability of loads having different requirements.
