The main body 11 is formed in a box shape having a certain space therein so as to receive power components for operation of the streetlight. The main body 11 includes a power supply unit 111, an on-off switch 112, A guide member 116 and an operation plate 117 may be formed outside the main body 11. The guide member 116 and the operation plate 117 may be formed integrally with each other. In particular, the main body 11 includes an on-off switch 112 having a unique structure in order to minimize energy consumption of the streetlight control board 1 itself. The main body 11 is accommodated in a closed space of the main body accommodating portion 13 so as not to be influenced by the external environment and is particularly accommodated on the upper side of the main body accommodating portion 13, It is possible to prevent the illegal operation of the streetlight control panel 1 from occurring.

The power supply unit 111 is configured to supply electric power to a street lamp so as to light the street lamp. The electric power supply unit 111 may be configured to receive electric power from a commercial power supply supplied from a power plant or the like, or to receive power from a separate battery can do. The power supply unit 111 supplies or blocks electric power to the street light L in accordance with the operation of the on-off switch 112.

The on / off switch 112 connects the power supply unit 111 and the streetlight L so that the electric power is supplied or the connection between the electric power supply unit 111 and the streetlight L is cut off, To minimize energy consumption through a unique structure. To this end, the on-off switch 112 allows power to be consumed only when the power is supplied to or blocked from the street light, and power consumption is prevented from being consumed while the power is supplied to or blocked from the street light. Also, since the on / off switch 112 does not use a power storage device such as a capacitor, it has no influence on the performance of a capacitor or the like, and the occurrence of a failure due to the surrounding environment or aging is fundamentally blocked. A detailed description thereof will be described later. The on-off switch 112 includes a fixed portion 112a for generating a magnetic force in accordance with the supply of a current, a moving portion 112b moving according to the magnetization of the fixed portion 112a, a power supply portion 111, And a contact part 112c connected to the moving part 112b and connected or disconnected according to the movement of the moving part 112b.

The fixed portion 112a is magnetized in accordance with the supply of the current for the operation of the on-off switch 112. The fixed portion 112a-4 is formed at a predetermined distance below the moving portion 112b. A coil part 112a-1 for magnetizing the fixed core 112a-4 in accordance with the supply of current by being wound around the outer circumferential surface of the fixed core 112a-4, and a coil part 112a-1 for supplying current to the coil part 112a-1 And a current switching unit 112a-3 for changing the direction of a current flowing through the coil part 112a-1.

The coil part 112a-1 is supplied with current or is interrupted according to the operation of the switching part 112a-2, and the current flowing direction is changed to change the magnetization direction of the fixed core 112a-4. Accordingly, the permanent magnet 112b-1 of the moving part 112b is pulled or pushed according to the magnetization direction of the fixed core 112a-4, so that the contact part 112c can be connected or disconnected. Even if the current supply to the coil part 112a-1 is cut off, the contact part 112c is connected or disconnected by the magnetized fixed core 112a-4 or the elastic body 112b-2 described later So that power is not consumed at all to maintain the power supply or shutdown state.

The coil section 112a-1 may be formed so as to be wound in one direction as shown in FIG. 3 (a). In this case, the coil section 112a-1 The direction of the current flowing through the fixed core 112a-4 is changed so that the direction in which the fixed core 112a-4 is magnetized can be changed. In this case, it suffices to connect only one switching part 112a-2 to one coil part 112a-1. Therefore, it is possible to simplify the structure, to reduce the occurrence of failure and to facilitate manufacture of the device .

Of course, the coil part 112a-1 may be formed by winding the upper connecting coil 112a- 'and the lower blocking coil 112a-1', which are formed to be wound in different directions as shown in FIG. 3 (b) A switching unit 112a-2 may be separately formed in each of the connection coil 112a 'and the blocking coil 112a-1' so that the connection coil 112a- 'and the blocking coil 112a-1' Quot; -1 ").

Regardless of whether the coil part 112a-1 is wound in one direction or divided into a connection coil 112a- 'and a blocking coil 112a-1' And the switching unit 112a-2 is operated so that the switching unit 112a-2 is operated simultaneously with the movement of the moving unit 112b in accordance with the supply of current to the coil unit 112a-1, So that the power consumption can be minimized.

The switching unit 112a-2 is configured to intermittently supply current by the coil part 112a-1, and is formed of a switch that operates only at the moment of pressing or releasing the pressing. As shown in FIG. 3, the switching unit 112a-2 is pressed against the permanent magnet fixing member 112b-4 of the moving unit 112b to be described later. When the switching unit 112a-2 is pressed or released, Cut off the supply. In other words, when the permanent magnet 112b-1 is pulled to connect the contact portion 112c, the permanent magnet fixing member 112b-4 contacts the switching portion 112a-2 at the moment when the contact portion 112c is connected The supply of current to the coil part 112a-1 is cut off by the operation of the switching part 112a-2 and when the permanent magnet 112b-1 is pushed to release the connection of the contact part 112c The permanent magnet fixing member 112b-4 releases the depression of the switching unit 112a-2 at the moment when the connection of the contact unit 112c is released so that the coil unit 112a-1 ) In response to a current flowing through the first and second electrodes.

In this case, when the coil part 112a-1 is formed as one as shown in FIG. 3 (a), the current supplied to the coil part 112a-1 is directed by the current switching part 112a-3 The switching unit 112a-2 instantaneously turns on when the current is supplied to the coil part 112a-1 and the permanent magnet fixing member 112b-4 presses or releases the switching part 112a-2 To cut off the supply of current to the coil portion 112a-1.

3 (b), when the coil portion 112a-1 is formed of the connecting coil 112a- 'and the blocking coil 112a-1', the switching portion 112a-2 is formed of Is formed to be connected to the connecting coil 112a 'and the blocking coil 112a-1', respectively, as shown in FIG. 5, divided into a connecting switch 112a-2 'and a breaking switch 112a-2 " The connection switch 112a-2 'is configured so that current is supplied only when the permanent magnet 112b-1 is pulled, and when the permanent magnet 112b-1 is pulled and the permanent magnet fixing member 112b-4 is connected to the connection switch 112a 2 '', the current is supplied only when the permanent magnet 112b-1 is pushed, and the permanent magnets 112b-1 'and 112b-1' Is pushed to interrupt the supply of current when the permanent magnet fixing member 112b-4 releases the pressing of the cutoff switch 112a-2 ".

Therefore, regardless of the shape of the coil part 112a-1, the switching part 112a-2 is supplied with current only when the current is supplied to the street light L or when the supply thereof is cut off, , And power consumption can be minimized. In addition, since the power supplied to the coil part 112a-1 is adjusted by supplying a separate power source to the switching part 112a-2, the current is charged by a capacitor or the like, Compared to a method in which current is supplied to the power supply, the risk of failure due to a capacitor or the like and the power loss can be reduced, and stable operation and energy consumption can be reduced.

When the current switching part 112a-3 is formed of one coil part 112a-1 as shown in FIG. 3 (a), currents in different directions are changed by changing the direction of current, ), Various circuits capable of switching the direction of the current can be used. As shown in FIG. 4 (a), the current switching unit 112a-3 includes two connection diodes 112a-1 and 112a-1 for rectifying the current input from one power source and supplying currents in different directions to the coil unit 112a-1. And a blocking diode 112a-3 ". The current direction of the current supplied to the coil part 112a-1 through the connection diode 112a-3 ' The direction of the current supplied to the coil portion 112a-1 through the blocking diode 112a-3 "is opposite to the direction of the current supplied to the permanent magnet 112b-1 of the fixed core 112a-4, The polarity changes and pulls or pushes the permanent magnet. As shown in FIG. 4B, the current switching unit 112a-3 rectifies the electric power input from the two power sources to supply currents of different directions to the coil part 112a-1. May be composed of the connection rectification circuit 112a-3 '' 'and the isolation rectification circuit 112a-3' ''.

The fixed core 112a-4 is wound around the outer circumferential surface of the coil portion 112a-1 and has an end portion facing the permanent magnet 112b-1 in accordance with the direction of the current flowing in the coil portion 112a-1 The polarity is changed. Therefore, when the fixed core 112a-4 is magnetized to have the same polarity as that of the end of the permanent magnet 112b-1, the permanent magnet 112b-1 is pushed upward and the end of the permanent magnet 112b- The permanent magnet 112b-1 is pulled downward.

The moving part 112b is configured to be lifted and lowered by the magnetic force generated by the fixed part 112a and includes a permanent magnet 112b-1 that is pulled or pushed according to the polarity of the fixed core 112a-4, An elastic body 112b-2 for keeping the magnet 112b-1 at a predetermined distance from the fixed core 112a-4 and a permanent magnet 112b-1 coupled to the upper side of the permanent magnet 112b- And a permanent magnet fixing member 112b-4 which is coupled to the lower side of the permanent magnet 112b-1 and elevated.

As described above, the permanent magnet 112b-1 is pulled or pushed according to the magnetization direction of the end of the fixed core 112a-4. When the permanent magnet 112b-1 is pulled, the moving member 112b-3 The contact 112b-3 'of the moving member 112b-3 is brought into contact with the contact portion 112c to supply electric current to the street lamp L. When the permanent magnet 112b-1 is pushed, The contactor 112b-3 'rises and the contactor 112b-3' is away from the contact portion 112c, and the supply of current to the streetlight L is interrupted. When the permanent magnet 112b-1 is pulled to contact the contact 112b-3 'with the contact portion 112c and the permanent magnet fixing member 112b-4 presses the switching portion 112a-2, (112a-1). When the permanent magnet 112b-1 pushes the contactor 112b-3 'away from the contact portion 112c, the permanent magnet fixing member 112b-4 releases the pushing of the switching portion 112a-2, The current supply to the coil portion 112a-1 is cut off.

The elastic body 112b-2 is a compression spring that is resiliently urged in a direction to push the permanent magnet 112b-1. When the contactor 112b-3 'is apart from the contact portion 112c, the permanent magnet 112b- -1 is prevented from being pulled toward the fixed core 112a-4 side so that a state in which current is not supplied to the street light L can be maintained.

The moving member 112b-3 is configured to be coupled to the upper side of the permanent magnet 112b-1 and move up and down with the lifting of the permanent magnet 112b-1. -3 ') are formed and allowed to ascend and descend together. Side contact 112c-1 and the streetlight side contact 112c-2, which contact the power supply side contact 112c-1 and the streetlight side side contact 112c-2, which will be described later, of the contact portion 112c, 112c-2 so that current can be supplied to the streetlight L. [0053] Accordingly, when the permanent magnet 112b-1 is pulled toward the fixed core 112a-4, the contact 112b-3 'contacts the contact portion 112c to allow current to flow, and the permanent magnet 112b-1' Is separated from the contact portion 112c when it is away from the fixed core 112a-4, the flow of current is cut off.

The contact portion 112c includes a power source side contact 112c-1 connected to the power supply 111 and a streetlight side contact 112c-2 connected to the streetlight L. As described above, the contact 112b- 3 ', the power supply side contact 112c-1 and the street lamp side contact 112c-2 are connected to supply the electric current to the street light L. When the contact is separated from the contact 112b-3' The connection between the power source side contact 112c-1 and the streetlight side contact 112c-2 is disconnected so that the supply of current is cut off.

Therefore, when the end portion of the fixed core 112a-4 is magnetized in the opposite polarity to the permanent magnet 112b-1 in accordance with the supply of current to the coil portion 112a-1, the permanent magnet 112b-1 is pulled The contactor 112b-3 'and the contact portion 112c are brought into contact with each other and a current is supplied to the streetlight L. At the same time, the permanent magnet fixing member 112b-4 presses the switching part 112a-2 to cut off the current supply to the coil part 112a-1, So that the permanent magnet 112b-1 remains attached.

When the end portion of the fixed core 112a-4 is magnetized to have the same polarity as that of the permanent magnet 112b-1 in accordance with the supply of current to the coil portion 112a-1, the permanent magnet 112b-1 is pushed The contactor 112b-3 'and the contact portion 112c are disconnected, and the current supply to the streetlight is interrupted. At the same time, the permanent magnet fixing member 112b-4 releases the depression of the switching unit 112a-2 to interrupt the supply of current to the coil unit 112a-1. Nevertheless, the elastic member 112b- The permanent magnet 112b-1 is maintained in a state in which the permanent magnet 112b-1 is spaced apart from the fixed core 112a-4, thereby maintaining a state in which current is not supplied to the street lamp.

Therefore, the on-off switch 112 of the present invention needs to supply current only at the time of supplying or interrupting current to the streetlight, and there is no power consumption for maintaining the current supply or blocking state, So that the power consumption is minimized. The on-off switch 112 may be configured not to use a power storage device such as a capacitor to change the magnetization direction of the fixed core 112a-4 but to use a switching part 112a-2 to switch the coil part Power is supplied to the capacitor 112a-1, so that 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 configured to store power required for the operation of the streetlight L and may be formed of a battery that is charged by a solar module or the like. The power storage unit 113 may supplement power to the streetlight L when power is not supplied from the commercial power supply. Further, the power storage unit 113 may include an electric power supply measuring sensor 113a for measuring an amount of electric power supplied and used, so that the stored electric power can be used to measure the amount used for the operation of the streetlight L .

The control unit 114 controls the operation of the main body 11, and the communication unit 115 communicates with a server for controlling the streetlight.

6, the guide member 116 is configured to move along the lifting rails 132c of the main body accommodating portion 13, which will be described later. The guide members 116 are formed of wheels, protrusions or the like protruding from both sides of the main body 11 And is inserted into the elevating rail 132c to be elevated. Accordingly, the main body 11 can be stably lifted and lowered along a predetermined path in the main body accommodating portion 13. [

The operation plate 117 is formed on the front surface of the main body 11 so as to enable the control of the streetlight. Since the main body 11 is present in the closed main body accommodating portion 13, The operation is possible only when the main body 11 is lowered and the operation plate 117 is exposed to the outside through the open area 134a to be described later.

The main body accommodating portion 13 is fixed to the street lamp post P to form a closed space and allows the main body 11 to be received between the street lamp post P. The main body 11 accommodated in the main body accommodating portion 13 is fixed in a state of being lifted to a height that can not be reached by an outside person and the main body 11 is lowered only when an authenticated user is confirmed, And the main body 11 can be controlled. 6, the main body accommodating portion 13 includes a closed housing 131, a lifting and driving portion 132, a lifting operation portion 133, and an opening and closing means 134.

If the electricity usage amount is measured as 200 KW, the usage amount calculation module 523b-1 "corrects the used electricity amount 200 KW based on the device information (200/2/2 x 2 = 100). Therefore, it can be judged that the specific streetlight has no abnormality.
