Hereinafter, with reference to the accompanying drawings, preferred embodiments of an energy-saving street lamp control panel and a solar street lamp system including the same according to the present invention will be described in detail. In the following description of the present invention, if it is determined that a detailed description of a known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. Throughout the specification, when a part is said to "include" any component, which means that it may further include other components, except to exclude other components unless specifically stated otherwise, also described in the specification The terms "... unit", "... module" and the like refer to a unit for processing at least one function or operation, which may be implemented by hardware or software or a combination of hardware and software.

When the energy saving street lamp control panel according to an embodiment of the present invention will be described with reference to FIGS. 1 to 8, the street lamp control panel 1 includes a box-shaped main body 11 in which power components for operation of the street lamp are accommodated. And a main body accommodating part 13 for accommodating the main body 11 to be fixed to the streetlight holder P.

The main body 11 is formed in the form of a box having a predetermined space therein to accommodate the power components for the operation of the street light, the power supply 111, the on-off switch 112, the power storage in the main body 11 The unit 113, the control unit 114, the communication unit 115, and the like may be accommodated, and the guide member 116 and the operation plate 117 may be formed outside the main body 11. In particular, the main body 11 is to include an on-off switch 112 having a unique structure in order to minimize the energy consumption of the street lamp control panel 1 itself. In addition, the main body 11 is accommodated in the closed space of the main body accommodating portion 13 so as not to be affected by the external environment, in particular accommodated above the main body accommodating portion 13 so that outsiders can not operate, By lowering to a position that can be operated only by an authenticated user, it is possible to block illegal operation of the street lamp control panel (1) at its source.

The power supply unit 111 is configured to supply power to the street light so that the street light is turned on, so as to receive power from commercial power supplied from a power plant, or to receive power from a separate battery charged by a solar module. can do. The power supply unit 111 supplies or cuts power to the street lamp L according to the operation of the on-off switch 112.

The on-off switch 112 connects the power supply 111 and the street light L to supply power, or cuts off the connection between the power supply 111 and the street light L to stop the supply of power. In this configuration, the energy consumption is minimized through a unique structure. To this end, the on-off switch 112 consumes power only at the moment when power is supplied to or cut off the street light, and no power is consumed while the street light is being supplied or cut off. In addition, since the on-off switch 112 does not use a power storage device such as a capacitor, the on-off switch 112 does not have an influence on the performance of the capacitor, and the like, thereby preventing the occurrence of a failure due to the surrounding environment or aging. Detailed description thereof will be described later. The on-off switch 112 is a fixed portion 112a for generating a magnetic force in response to the supply of current, a moving portion 112b moving in accordance with the magnetization of the fixed portion 112a, the power supply 111 and the street light (L) It is connected to each side and includes a contact portion (112c) connected or disconnected in accordance with the movement of the moving portion (112b).

The fixing part 112a is magnetized according to the supply of current for the operation of the on-off switch 112, and the fixing iron core 112a-4 is formed at a predetermined interval below the moving part 112b. The coil unit 112a-1 is wound around the outer circumferential surface of the fixed iron core 112a-4 to magnetize the fixed iron core 112a-4 according to the supply of the current, and the supply of the current to the coil unit 112a-1. It may include a switching unit 112a-2 for intermittent and a current switching unit 112a-3 for changing the direction of the current flowing through the coil unit 112a-1.

The coil unit 112a-1 is supplied with or cut off current according to the operation of the switching unit 112a-2, and the direction in which the current flows is changed to change the direction in which the fixed iron core 112a-4 is magnetized. Accordingly, the permanent magnet 112b-1 of the moving part 112b may be pulled or pushed along the magnetization direction of the fixing core 112a-4 so that the contact part 112c may be connected or disconnected. In addition, even when the supply of current to the coil unit 112a-1 is blocked, the contact portion 112c is connected or disconnected by the magnetized fixed core 112a-4 or the elastic body 112b-2 to be described later. So that no power is consumed to keep the power on or off.

In addition, the coil part 112a-1 may be formed to be wound in one direction as shown in FIG. 3 (a). In this case, the coil part 112a-1 is formed by the current switching part 112a-3. The direction of the current flowing through the) is changed so that the direction in which the fixed iron core 112a-4 is magnetized can be changed. In such a case, it is sufficient to connect only one switching unit 112a-2 to one coil unit 112a-1, which simplifies the structure, thereby reducing the occurrence of failure and facilitates the manufacture of the device. There is this.

Of course, the coil part 112a-1 may have an upper connection coil 112a- 'and a lower blocking coil 112a-1 " formed so as to be wound in different directions as shown in FIG. In this case, a switching unit 112a-2 is formed separately in each of the connection coil 112a- 'and the blocking coil 112a-1 ", so that the connection coil 112a-' and the blocking coil 112a are separately formed. -1 ") to interrupt the supply of current.

The coil part 112a-1 may be wound in one direction, or may be divided into a connection coil 112a- 'and a cutoff coil 112a-1 ". Is cut off, and the switching unit 112a-2 is made smaller with the movement of the moving unit 112b according to the supply of the current to the coil unit 112a-1, and thus, the operating moment of the moving unit 112b. Only by supplying the current and the current supply is cut off immediately, it is possible to minimize the power consumption.

The switching unit 112a-2 is configured to interrupt the supply of current by the coil unit 112a-1, so that the switching unit 112a-2 is formed as a switch that operates only at the moment of being pressed or released. As shown in FIG. 3, the switching unit 112a-2 is pressed in contact with the permanent magnet fixing member 112b-4, which will be described later, of the moving unit 112b, and is pressed or released when the current is released. Shut off the supply. In other words, when the permanent magnet 112b-1 is pulled and the contact portion 112c is connected, the permanent magnet fixing member 112b-4 moves the switching unit 112a-2 the moment the contact portion 112c is connected. Press to cut off the supply of current to the coil unit 112a-1 according to the operation of the switching unit 112a-2, and when the permanent magnet 112b-1 is pushed to disconnect the contact unit 112c. The moment the connection of the contact portion 112c is released, the permanent magnet fixing member 112b-4 releases the pressing of the switching unit 112a-2, and the coil unit 112a-1 according to the operation of the switching unit 112a-2. Cut off the supply of current.

In this case, as shown in FIG. 3A, when the coil parts 112a-1 are formed as one, the current supplied to the coil parts 112a-1 is oriented by the current switching unit 112a-3. Since the current is supplied to the coil part 112a-1, the switching part 112a-2 is instantaneously released when the permanent magnet fixing member 112b-4 presses or releases the switching part 112a-2. In operation, the supply of current to the coil unit 112a-1 is interrupted.

In addition, as shown in FIG. 3B, when the coil part 112a-1 is formed of the connection coil 112a-′ and the blocking coil 112a-1 ″, the switching unit 112a-2 is formed. As shown in FIG. 5, the switch is divided into a connection switch 112a-2 ′ and a disconnect switch 112a-2 ″ so as to be connected to the connection coil 112a-′ and the blocking coil 112a-1 ″, respectively. The connection switch 112a-2 'allows the current to be supplied only when pulling the permanent magnet 112b-1, and the permanent magnet 112b-1 is pulled so that the permanent magnet fixing member 112b-4 is connected to the connection switch 112a. The current is supplied only when the permanent magnet 112b-1 is pushed, and the permanent magnet 112b-1 is cut off. ) Is pushed to block the supply of current when the permanent magnet fixing member 112b-4 releases the pressing of the cutoff switch 112a-2 ".

Therefore, the switching unit 112a-2 is supplied with the current only at the moment when the current is supplied to the street lamp L or the supply is cut off regardless of the shape of the coil unit 112a-1, and thus the supply of the current is cut off immediately. Therefore, the power consumption can be minimized. In addition, the present invention is to supply a separate power to the switching unit (112a-2) so that the adjustment of the power supplied to the coil unit (112a-1) is made, by charging a current by a capacitor or the like to different two coils Compared to the way the current is supplied in the direction, it is possible to reduce the risk of failure due to condensers and power loss, thus enabling stable operation and reducing energy consumption.

When the current switching unit 112a-3 is formed of one coil unit 112a-1, as shown in FIG. 3 (a), currents in different directions are changed by changing the direction of current. ), Various circuits capable of diverting the current can be used. As shown in FIG. 4 (a), the current conversion unit 112a-3 rectifies electricity input from one power source and supplies two connection diodes for supplying current in different directions to the coil unit 112a-1. 112a-3 'and a blocking diode 112a-3 ". The direction of the current when the current is supplied to the coil part 112a-1 through the connection diode 112a-3'. When the current is supplied to the coil unit 112a-1 through the blocking diode 112a-3 ″, the directions thereof are opposite to each other, so that the permanent magnet 112b-1 of the fixed iron core 112a-4 is opposite to each other. The polarity changes so that the permanent magnet is pulled or pushed. In addition, the current switching unit 112a-3 rectifies electricity input from two power sources as shown in FIG. 4 (b) and supplies two currents in different directions to the coil unit 112a-1. The connection rectification circuit 112a-3 "'and the blocking rectification circuit 112a-3" "may be comprised.

The fixed iron core 112a-4 is wound around the outer circumferential surface of the coil part 112a-1 and is opposite to the permanent magnet 112b-1 in the direction of the current flowing in the coil part 112a-1. The polarity will change. Therefore, when the fixed iron core 112a-4 is magnetized to the same polarity as the end of the permanent magnet 112b-1, the fixed magnet core 112a-4 pushes the permanent magnet 112b-1 upward, and the end of the permanent magnet 112b-1. When magnetized in the opposite polarity and the permanent magnet 112b-1 is pulled downward.

The moving part 112b is configured to be elevated by the magnetic force generated by the fixing part 112a, and the permanent magnet 112b-1 that is pulled or pushed according to the polarity of the fixed iron core 112a-4, and permanently. The magnet 112b-1 is coupled to the upper side of the permanent magnet 112b-1 and the elastic body 112b-2 to maintain a constant distance from the fixed core 112a-4, together with the permanent magnet 112b-1. It includes a moving member (112b-3) to be moved up and down, permanent magnet fixing member (112b-4) coupled to the lower side of the permanent magnet (112b-1).

As described above, the permanent magnet 112b-1 is pulled or pushed according to the magnetization direction of the end of the fixed iron core 112a-4, and the movable member 112b-3 is pulled when the permanent magnet 112b-1 is pulled. When the contact member 112b-3 ', which will be described later, of the moving member 112b-3 is brought into contact with the contact portion 112c, and the current is supplied to the street lamp L, the moving member 112b-1 is pushed down. As 112b-3 rises, the contact 112b-3 'becomes far from the contact portion 112c, so that the supply of current to the street light L is cut off. Further, the permanent magnet 112b-1 is pulled so that the contactor 112b-3 'comes into contact with the contact part 112c, and the permanent magnet fixing member 112b-4 presses the switching part 112a-2 to coil part. The supply of current to 112a-1 is cut off. When the permanent magnet 112b-1 is pushed to move the contact 112b-3 'away from the contact part 112c, the permanent magnet fixing member 112b-4 releases the pressing of the switching part 112a-2 and opens it. The supply of current to the coil part 112a-1 is cut off.

The elastic body 112b-2 is a compression spring in which elasticity acts in the direction of pushing the permanent magnet 112b-1, and the permanent magnet 112b is disposed in a state where the contact 112b-3 'is separated from the contact portion 112c. -1) is prevented from being pulled toward the fixed core (112a-4) side to maintain a state in which no current is supplied to the street lamp (L).

The movable member 112b-3 is coupled to the upper side of the permanent magnet 112b-1 to move up and down with the permanent magnet 112b-1, and contacts 112b are provided on both sides of the movable member 112b-3. -3 ') are formed and allowed to lift together. The contactors 112b-3 'on both sides contact the power supply side contact 112c-1 and the streetlight side contact 112c-2, which will be described later, of the contact portion 112c, so that the power supply side contact 112c-1 and the street light side contact ( The current flows between 112c-2), thereby allowing the current to be supplied to the street lamp L. FIG. Therefore, when the permanent magnet 112b-1 is pulled toward the fixed iron core 112a-4, the contactor 112b-3 'contacts the contact portion 112c so that a current flows, and the permanent magnet 112b-1. ) Is separated from the contact point (112a-4) is separated from the contact portion (112c) to block the flow of current.

The contact portion 112c includes a power supply side contact 112c-1 connected to the power supply 111 and a streetlight side contact 112c-2 connected to the street light L. As described above, the contactor 112b is used. -3 ') when the power supply side contact 112c-1 and the street light side contact 112c-2 are connected to supply a current to the street light L, and is separated from the contact 112b-3'. The connection of the power supply side contact 112c-1 and the street light side contact 112c-2 is disconnected so that the supply of current is blocked.

Therefore, when the end of the fixed iron core (112a-4) is magnetized in the opposite polarity to the permanent magnet (112b-1) in accordance with the supply of the current to the coil portion (112a-1) the permanent magnet (112b-1) is pulled The contact 112b-3 'and the contact portion 112c come into contact with each other to supply a current to the street light L. FIG. At the same time, the permanent magnet fixing member 112b-4 presses the switching unit 112a-2 to cut off the supply of current to the coil unit 112a-1, and yet to the magnetized fixed core 112a-4. As a result, the permanent magnet 112b-1 is maintained.

In addition, when the end of the fixed core (112a-4) is magnetized to the same polarity as the permanent magnet (112b-1) in response to the current supply in the opposite direction to the coil portion (112a-1), the permanent magnet (112b-1) is pushed The contact 112b-3 'and the contact portion 112c are separated to cut off the supply of current to the street lamp L. FIG. At the same time, the permanent magnet fixing member 112b-4 releases the pressing of the switching unit 112a-2 to cut off the supply of current to the coil unit 112a-1, and yet the elastic body 112b-2. As a result, the permanent magnets 112b-1 maintain the state in which the permanent magnets 112a-4 are spaced apart from the fixed iron cores 112a-4, thereby maintaining a state in which no current is supplied to the street lamp L.

Therefore, the on-off switch 112 of the present invention requires the supply of the current only at the time of supplying or blocking the current to the street light, so that there is no power consumption for maintaining the current supply or blocking state, and at the time of supplying or blocking the current. In addition, the power supply is automatically cut off to minimize power consumption. In addition, the on-off switch 112 does not use a power storage device such as a capacitor to change the magnetization direction of the fixed core (112a-4), the coil unit from a separate power supply using a switching unit (112a-2) Since power is supplied to the 112a-1, the risk of failure and power loss due to the use of a capacitor or the like can be prevented.

The power storage unit 113 is a configuration for storing the power required for the operation of the street lamp (L), it may be formed of a battery that is charged by the solar module. The power storage unit 113 may supplementally supply power to the street lamp L when power is not supplied from a commercial power source. In addition, the power storage unit 113 may include an electricity supply amount measuring sensor 113a that measures the amount of power supplied and used, so that the stored power measures the amount used for the operation of the street lamp L. FIG. .

The control unit 114 controls the operation of the main body 11, the communication unit 115 to communicate with a server for controlling the street light.
