That is, the output driver 115 is a component that outputs a driving voltage so as to be operated in accordance with the type controlled by the actual streetlight 1. [

Also, the control apparatus main body 110 of the present embodiment can be configured to include the function of the external interface section 122 of the module control section 121. That is, it is possible to additionally configure a body interface unit, which is a constituent part for interfacing the wide area wired / wireless network and signals from the local wired and wireless network, to the main body 110 of the control unit by selectively connecting the wide area wired and wireless network and the local wired and wireless network.

The control unit main body 110 and the external control module 120 can be selectively connected and communicated with signals from the wide-area wired / wireless network and the local wired / wireless network according to the selective connection of the main body interface unit under the control of the central control unit 111 . The control unit main body 110 is also connected to the external control module detachable streetlight control device 10 like the external interface unit 122 of the module control unit 121 to receive various external wired and wireless signals And it is possible to receive or output various signals in the state of selectively connecting and connecting.

The external interface unit 122 selectively connects the wide-area wired / wireless network and the local wired / wireless network under the control of the module control unit 121 and transmits the signals from the wide-area wired network and the local wired / wireless network to the external control module 120 . That is, the external interface unit 122 is connected to receive various external wired and wireless signals connected to the external control module 120 of the external control module detachable type streetlight controller 10, And wireless signals are connected, and various signals are transmitted or received in a connected state.

As shown in FIG. 4, when the external control module detachable type streetlight control apparatus 10 having such a configuration is activated, it is possible to control the streetlight 1 through various networks according to the management of the administrator (user). This is because various networks can be connected and controlled through the external control module 120 according to the present embodiment and can be controlled according to the connection state.

First, let's look at a case where the external control module detachable type street lamp control device 10 starts operating at an early stage. For example, when an administrator emits a control signal corresponding to the transmission of a control signal to each streetlight 1 through a wireless network, the control path is analyzed by grasping the network having the control signal.

[It is generally installed in the street light itself (street light) installed in each street light 1, but there is no restriction on the installation location or place. It may be installed in the streetlight itself or near the streetlight outside the streetlight.) The external interface unit 122 of the external control module 120 receives the control signal. Even in the case of a wired network, there may be slight differences in the setting and selection of the control path, but the overall concept is the same.

The initial control signal received from the external interface unit 122 of the external control module 120 is transmitted to the module control unit 121 and the module control unit 121 analyzes the control signal.

Then, the external control module detachable type streetlight controller 10 determines which network to receive the control signal to determine the control path.

In the external interface unit 122, signals that can be input or input from the network connected to the external control module 120 are continuously received and analyzed. Through this process, it is possible to switch to control the street light 1 by a signal coming into another network.

That is, according to the determination, a specific network among the various networks connected to the external control module detachable streetlight control device 10 is connected and a control signal for controlling the corresponding streetlight 1 is inputted.

The actual control signal for controlling the streetlight 1 inputted through the external interface unit 122 is transmitted to the module interface unit 112 of the next main body 110 of the control unit.

The control signal transmitted to the module interface unit 112 is analyzed in full by the analysis operation unit 113.

When the initial control is started, the analysis operation unit 113 receives environmental information signals sensed by the sensing unit 114 in parallel with the input and analysis of the control signals.

Then, the input of the environmental information signal necessary for the control of the streetlight 1 is determined in accordance with the interpretation of the control signal. Accordingly, an environmental information signal required through each sensor is detected and input is started.

The analysis calculation unit 113 computes the final control signal of the final streetlamp 1 to control the streetlamp 1 according to the conditions such as the external environment and the climate through the environment information signal, And informs it to the central control unit 111.

The central control unit 111 is notified that the final control signal is operable and controls the output driving unit 115 to output the final control signal.

The output drive unit 115 generates the drive voltage suitable for the state of the streetlight 1, that is, the type of the streetlight 1, and drives the output to the corresponding streetlight 1 to control the streetlight 1 .

Let's look at some examples of the control performed by the external control module detachable streetlight control device 10.

First, regarding the dimming of the basic one, it is possible to control the corresponding street light 1 to be turned on and off through a configuration including a photo coupler, which is one of the light intensity sensors. In addition, it is also possible to control the exterior control module detachable type streetlight control device 10 to light up brightly in accordance with a specific time period, for example, in the evening before midnight when a lot of people pass by.

Also, it is possible to include an infrared sensor in a plurality of sensors. Accordingly, it is possible to radiate infrared rays and receive infrared rays reflected from the object to judge whether the object is an object. Thus, it can be controlled such that a person or an animal is detected within a predetermined distance, for example, within about 30 meters from the streetlight,

It is also possible to include an ultrasonic sensor. Therefore, it is also necessary to radiate ultrasonic waves to an object, to receive ultrasonic waves reflected from the object, to process the ultrasonic waves over time, and to control the street light 1 to light up when an automobile or a bicycle approaches or approaches the street light 1 It is possible.

In addition, in the present invention, street lamps can control not only general lamps (lamps) but also mercury lamps, sodium lamps, LEDs and the like. In the case of LED street lamps, it is necessary to further configure the LED module, but the concept of overall control is possible within the scope of control through this embodiment.

It goes without saying that the external control module detachable type streetlight control device 10 is also controlled by a streetlight which is composed of a plurality of various power generation units such as a solar cell (solar cell) and a wind power generator.

In addition, it is also possible to set each streetlight in the form of a group in advance and to control by applying sunrise and sunset time according to the set group.

In addition, by receiving control signals through various external lines through the external control module detachable type streetlight controller 10 of the present embodiment, the street lights can be turned on in a state suitable for the current situation and the external environment. This satisfies the various external control conditions and other device upgrades, so it is convenient to control the streetlight. In addition, this configuration can prevent a situation in which the configuration of the " control device " itself needs to be changed according to the situation and the control state, thereby reducing the operating cost.

It is to be understood that the present invention is not limited thereto and that various changes and modifications may be made by those skilled in the art without departing from the scope of the present invention It is to be understood that these various implementations fall within the scope of the present invention.
