Description

Smart lighting device with BLE mesh group setting and lighting control method using the same {Smart lighting device with BLE mesh group setting and lighting control method using the same}

The present invention relates to a smart lighting device, and more particularly, to a smart lighting device capable of setting a BLE mesh group and a lighting control method using the same.

As sensor network technology develops, research and development on smart lighting technology that can control lighting fixtures by attaching sensors to lighting fixtures is being actively conducted.

Smart lighting technology can increase the operator's convenience when operating multiple lights. However, even in the case of smart lighting, there is a problem in that the installation worker must directly set the individual lighting when constructing it, and if an error occurs in the setting operation for a plurality of lights, re-construction or changing the setting information is required.

When dozens or hundreds of individual lights are installed in a specific location of a building, each light has identification information. While installing individual lights, the operator matches the identification information and the installation location of the corresponding lights and arranges them into a database, and builds a control system for controlling a plurality of lights based on this database.

During this installation process, if a worker installs lighting differently from the construction plan without distinguishing the identification information of lighting, or if incorrect information is entered into the database even if it is installed correctly, the lighting cannot be controlled correctly. Difficulties to be corrected were noted.

In order to solve this difficulty, when lighting is recognized and registered, there is a need for developing a lighting system capable of self-grouping settings so that registered lights can identify each other and perform grouping according to common elements.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. The smart lighting device described below has been described only with essential components within the scope of understanding the technical concept of the present invention, and may be designed with additional configurations or similar configurations within the scope of the technical concept.

1 is a diagram illustrating a smart lighting device capable of self-grouping settings according to an embodiment of the present invention by way of example. Referring to FIG. 1 , a smart lighting device (100, hereinafter referred to as a smart lighting device) capable of self-grouping settings according to an embodiment of the present invention includes a low-power wireless communication unit 110 and a lighting unit 130.

The low power wireless communication unit 110 includes Bluetooth Low Energy (BLE) and an input/output interface module. Here, the input/output interface includes GPIO and communication interface. GPIO and communication interface can be expanded with various switches and serial communication interface terminals that can be added or replaced.

Specifically, a general purpose input output (GPIO) refers to a digital signal pin of an integrated circuit or electronic circuit board whose operation including input or output can be controlled by a user at runtime. GPIOs have no predefined purpose and are not used by default. GPIOs are implemented by assembly-level circuitry designers (circuit board designers in the case of integrated circuit GPIOs, system integrators in the case of board-level GPIOs, S/I). When using this, the purpose and operation of GPIO can be defined.

The communication interface terminal may be implemented as a serial communication interface. Here, the serial communication interface is a communication method that transmits and receives data using one or two transmission lines. Various methods such as UART, USB, SPI, and I2C can be applied to the serial communication interface.

UART (Universal asynchronous receiver/transmitter) is a type of computer hardware that transmits data by converting the form of parallel data into a serial method. UART is commonly used with communication standards such as EIA RS-232, RS-422, and RS-485. The communication data of UART is stored in memory or register, and it is read sequentially and serialized for communication. A maximum of 8 bits is the basic unit.

Universal Serial Bus (USB) is an input/output standard protocol used to connect hardware (e.g., a computer) and peripheral devices.

The Serial Peripheral Interface Bus (SPI) is a synchronous serial data connection standard named after the Motorola architecture that operates in an architectural full-duplex communication mode. Devices communicate in master-slave mode, where the master device initiates data frames. Multiple slave devices can operate with individual slave select (chip select) lines.

I2C (Inter-Integrated Circuit) is a serial bus developed by Philips. It is a serial communication interface used to connect low-speed peripherals such as motherboards, embedded systems, mobile phones, etc.

According to an embodiment of the present invention, an input/output interface between the low power wireless communication unit 110 and the lighting unit 130 by additionally connecting a sliding switch, an encoder switch, a dip switch, etc. to the GPIO. method can be set. Group information may be transmitted to the corresponding smart lighting device 100 according to the interface method set in this way so as to achieve self-grouping.

Here, a self-formed mesh network is a network topology in which each node (smart lighting device) relays data to the network. All mesh nodes cooperate in the propagation of control signals within the network. Such a mesh network can be applied to both a wireless method and a wired method.

In the case of the present invention, a detailed description of how the smart lighting device can be grouped by itself according to the setting of the input/output interface module will be described with reference to separate drawings.

2 is a diagram illustratively illustrating an embodiment of grouping according to group information input using a sliding switch according to an embodiment of the present invention. Referring to FIG. 2(a) , for a plurality of smart lighting devices 100-1 to 100-3, the corresponding lighting unit 130 is operated by positioning a sliding switch connected to a GPIO to a first position. Group information is delivered as first grouping information. That is, the first grouping for self-grouping the corresponding smart lighting devices 100-1 to 100-3 into the first group by manipulating the button to the first position using the sliding switch for the plurality of smart lighting devices 100. convey information In other words, when the grouping information of the lighting unit 130 is input as the first grouping information through the GPIO by the sliding switch, the plurality of smart lighting devices 100-1 to 100-3 to which the first grouping information is input are controlled under the same control. Since it can be equally collectively controlled by a signal (a signal for controlling the smart lighting devices set as the first grouping information), it means that they operate as one group.

Referring to FIG. 2(b) , a method of inputting grouping information using a sliding switch can be confirmed. By placing the sliding switch in the first position, the plurality of smart lighting devices 110-1 to 110-3 are self-grouped into the first group. The plurality of smart lighting devices 110-1 to 110-3 receiving the first grouping information through the GPIO interface in this way form a mesh network as a first group. In the same way, the sliding switch is positioned at the fourth position to self-group the plurality of smart lighting devices 110-4 to 110-5 into the second group. The plurality of smart lighting devices 110 - 4 to 110 - 5 receiving the second grouping information through the GPIO interface form a mesh network as a second group.

3 is a diagram illustratively illustrating an embodiment of inputting grouping information using an encoder switch or a dip switch according to another embodiment of the present invention. Referring to FIG. 3 (a), a plurality of smart lighting devices (100-6 to 100-10) are connected to GPIOs by using encoder switches or dip switches. 100-6 to 100-10) may deliver each grouping information.

Specifically, the smart lighting devices 100-6 to 100-8 can be self-grouped into a third group by placing the button in the second position using the encoder switch. By manipulating the button to move the encoder switch to the second position, third grouping information can be transmitted to the plurality of smart lighting devices 100-6 to 100-8, and the corresponding smart lighting devices 100-6 to 100-8 will form its own group as the third group. That is, when the plurality of smart lighting devices 100-6 to 100-8 are set as the third group through the GPIO by the encoder switch, the plurality of smart lighting devices 100-6 to 100-8 self-grouped into the third group 8) can be equally collectively controlled by the same control signal (signal for controlling the smart lighting devices set to the third group), meaning that they operate as one group.

Referring to FIG. 3(b) , it can be seen how to set the third group using an encoder switch and how to set a fourth group using a dip switch. By placing the encoder switch in the second position, the plurality of smart lighting devices 110-6 to 110-8 are set to self-group into a third group. The plurality of smart lighting devices 110 - 6 to 110 - 8 receiving the third group information in this way form a mesh network by themselves as a third group. In the same manner, the plurality of smart lighting devices 110 - 9 to 110 - 10 are set to self-group into a fourth group by positioning the dip switch to the first set value. The plurality of smart lighting devices 110 - 9 to 110 - 10 receiving the fourth group information in this way form a BLE mesh network group by themselves as the fourth group.

4 is a diagram illustratively illustrating a result of grouping for a plurality of smart lighting devices according to an embodiment of the present invention. Referring to FIG. 4(a) , by placing the sliding switch in the first position, the plurality of smart lighting devices 100-1 to 100-3 receiving first group information through the GIPO interface connect to the first BLE mesh network. It is set to self-group as a group.

Referring to FIG. 4 (b), by placing the sliding switch in the fourth position, the plurality of smart lighting devices 100-4 to 100-5 receiving the second group information through the GIPO interface are connected to the second BLE mesh network. It is set to self-group as a group.

Referring to FIG. 4(c) , by placing the encoder switch in the first position, the plurality of smart lighting devices 100-6 to 100-8 receiving the third group information through the GIPO interface are connected to the third BLE mesh network. It is set to self-group as a group.

Referring to FIG. 4 (d), by setting the value of the dip switch to the first set value, the plurality of smart lighting devices 100-9 to 100-10 receiving the fourth group information through the GIPO interface It is set to self-group as a BLE mesh network group.

FIG. 5 is a view illustrating a method of controlling lighting for a plurality of grouped smart lighting devices shown in FIG. 4 by way of example. Referring to FIG. 5 , a plurality of smart lighting devices 100-1 to 100 are transmitted by transmitting group information for each BLE network group through an interface for each of the 10 smart lighting devices 100-1 to 100-10. -10) to enable self-grouping for each BLE network group.

At this time, the plurality of smart lighting devices 100-1 to 100-10 are grouped into a plurality of groups (first to fourth groups), so that the smart lighting devices of the same group perform the same control operation for a specific control signal. .

For example, the first control signal generated from the electronic device 200 is transmitted to the plurality of smart lighting devices 100-1 to 100-10. The first control signal includes group identification information and control information. The group identification information of the first control signal includes values of "Dip Switch" and "101", and the control information includes power-on information. When such a first control signal is transmitted to the plurality of smart lighting devices 100-1 to 100-10, it is received by at least one smart lighting device for each group. At this time, among the smart lighting devices receiving the first control signal, the smart lighting devices 100 - 9 and 100 - 10 matching the group identification information perform a control operation according to the first control signal. However, the smart lighting devices 100-1 to 100-8 that do not match the group identification information included in the first control signal do not execute a control operation according to the received first control signal. That is, according to the first control signal, the ninth smart lighting device 100-9 and the tenth smart lighting device 100-10 operate to turn on power. On the other hand, the remaining smart lighting devices 100-1 to 100-8 do not perform a separate operation despite the first control signal.

In this way, by transmitting grouping information to a plurality of smart lighting devices through the input/output interface, the smart lighting devices receiving the same group information can group themselves into the same BLE network group and control them using the same control signal.

In this way, when grouping information is transmitted to a plurality of smart lighting devices through an input/output interface, the smart lighting device receiving the same group information operates as one node, and the plurality of nodes form a mesh network. An example of forming a mesh network will be described with reference to separate drawings.

6 is a diagram for explaining an example in which smart lighting devices according to an embodiment of the present invention are arranged and grouped 4×7. Referring to FIG. 6 , the first group is composed of a first node, a third node, an eighth node, and a ninth node. The second group is composed of a third node, a fourth node, a fifth node, a sixth node, a tenth node, an eleventh node, a twelfth node, and a thirteenth node. The third group consists of 15th to 20th nodes. The fourth group is composed of the seventh node, the fourteenth node, and the twenty-first node. Nodes 22 to 28 remain in an unassigned state in which a group has not been formed because group information has not yet been transferred through the input/output interface.

As shown in FIG. 6, a plurality of 28 smart lighting devices arranged in a 4×7 matrix are treated as 28 nodes, and the smart lighting devices receiving the same group information through the input/output interface form the same group on their own. will do The smart lighting device belonging to the same group may be composed of only one or a plurality of smart lighting devices. Hereinafter, an example of forming a mesh network by a plurality of nodes will be described with reference to separate drawings.

FIG. 7 is a diagram for explaining an example of forming a mesh network for each group shown in FIG. 6 . Referring to FIG. 7, the first group is composed of nodes 1, 2, 8, and 9, and a first BLE mesh network group is built by these nodes (see FIG. 7 (a)). The second group is composed of nodes 3, 4, 5, 6, 10, 11, 12, and 13, and a second BLE mesh network group is built by these nodes (see FIG. 7 (b)). The third group is composed of nodes 15, 16, 17, 18, 19, and 20, and a third BLE mesh network group is built by these nodes (see FIG. 7(c)). The fourth group is composed of the 7th, 14th, and 21st nodes, and the 4th BLE mesh network group is built by these nodes (see FIG. 7(d)).

When a control signal is received in the first mesh group composed of the first group shown in FIG. 7, the control signal is transmitted to neighboring nodes in addition to nodes belonging to the first group matching the group identification information. In addition, when the second control signal is received by the twelfth node belonging to the second group, other nodes belonging to the second group matching the group identification information (second grouping information) included in the second control signal also receive the second control signal. It transmits a control signal. In addition, when the 16th node belonging to the third group receives the third control signal, the other nodes belonging to the third group that match the group identification information (third grouping information) included in the third control signal also receive the third control signal. signal is transmitted. In addition, when the fourth control signal is received by the 21st node belonging to the fourth group, other nodes belonging to the fourth group that match the group identification information (fourth grouping information) included in the fourth control signal also receive a second control signal. 4 It transmits the control signal.

FIG. 8 is a diagram for explaining an example of updating nodes within the mesh network group shown in FIG. 7 . Referring to FIG. 8, a third node is added to the first group shown in FIG. 7, the third node is removed from the second group to update the first mesh network, and the second mesh network is updated to add a node and removal may be reflected.

Compared to this method of the present application, according to the node update method of the existing BLE mesh group, there is a hassle of individually grouping using a smart pad or a smart terminal for all nodes (28 nodes).

Compared to these conventional methods, the present invention can remove a corresponding smart lighting device from an existing group and easily register it in a new group simply by transmitting or changing grouping information through the input/output interface of the corresponding smart lighting device. That is, in the existing BLE mesh method, a grouping procedure had to be performed for the nodes constituting the group for grouping, but the present invention does not require a separate procedure for group configuration setting in the BLE mesh. It is possible to add/remove a corresponding smart lighting device from an existing BLE mesh group and register it in a new group simply by changing the grouping information through this.

9 is a flowchart illustrating a lighting control method using a smart lighting device according to another embodiment of the present invention by way of example. Referring to FIG. 9 , the lighting control method executes a step (S910) of transmitting grouping information to a smart lighting device through an input/output interface. The method of transmitting grouping information through the input/output interface is to input grouping information through the input/output interface by manipulating the switch connected to the GPIO for the smart lighting device or by transmitting the group information through the serial communication interface to be specific for the corresponding smart lighting. Groups can be set to enable self-grouping.

The smart lighting devices 100 are self-grouped into the same group when the group information input through the input/output interface is the same, and each smart lighting device 100 functions as a node in the group, and forms a group in the BLE mesh network. form When the control signal is received, group information is checked, and only when the group information matches its own group information, the low-power wireless communication unit 110 transfers the corresponding control signal to the lighting unit 130. The low power wireless communication unit 110 transmits the control signal to other nodes belonging to the mesh network in a broadcasting manner (S930).

10 is a diagram for explaining a problem that occurs when some nodes are changed in a grouping result. Referring to FIG. 10, in order to remove the 13th node of the second group from the second mesh network and add the 13th node to the first mesh network of the first group, the existing method is to create and assign a network identifier through provisioning. After that, the first mesh network and the second mesh network can be updated through a grouping step. Compared to the method according to the present invention, this method has a more complex grouping method and must go through provisioning to identify smart lighting devices. Therefore, even when some additions or changes occur to the entire network, the same procedure as the method of registering a new device is followed. The problem is that the procedure is complicated.

In contrast, the present invention transmits group information to a smart lighting device through an input/output interface capable of various settings, so that it can be set to perform self-grouping. In this method, a node can be set as a desired group without information about the node, and thus, a method of changing a lighting group is greatly simplified.

Although the preferred embodiments of the present invention have been shown and described above, the present invention is not limited to the specific embodiments described above, and is common in the art to which the present invention pertains without departing from the gist of the present invention claimed in the claims. Of course, various modifications and implementations are possible by those with knowledge of, and these modifications should not be individually understood from the technical spirit or perspective of the present invention.
