Referring to FIG. 1, a block device 1 for an IoT service according to an embodiment may include a main block 100, a plurality of sensor blocks 200, and a plurality of peripheral block 300. As illustrated in FIG. 1, the main block 100, the sensor block 200, and the peripheral block 300 may be electronic devices in the form of blocks that may be assembled with each other, such as a LEGO ^™ block.

The main block 100 is a block to which the sensor block 200 and / or the peripheral block 300 are coupled. The main block 100 may have a rectangular or square plate shape, but may have a size large enough to allow the plurality of sensor blocks 200 and / or the plurality of peripheral blocks 300 to be assembled.

According to an embodiment, a plurality of coupling protrusions 110 are formed on an upper surface of the main block 100. The plurality of coupling protrusions 110 each have a flat cylindrical shape.

A portion of the power supply terminal 112 is exposed around the upper surface of the coupling protrusion 110, and the remaining portion is disposed on the outer circumferential surface of the coupling protrusion 110 along the height direction of the coupling protrusion 110. A portion of the ground terminal 113 is exposed around the upper surface of the coupling protrusion 110, and the remaining portion is disposed on the outer circumferential surface of the coupling protrusion 110 along the height direction of the coupling protrusion 110.

According to an embodiment, the ground terminal 113 and the power supply terminal 112 are disposed to form a predetermined angle with respect to the data terminal 111. For example, the angle between the ground terminal 113 and the power supply terminal 111 may be 45 degrees, 90 degrees, or 180 degrees.

When the angle between the ground terminal 113 and the power supply terminal 112 is 45 degrees, a total of eight terminals may be disposed in one coupling protrusion 110. In this case, eight terminals may include, for example, four ground terminals 113 and four power terminals 112, which may be alternately disposed along the circumference of the corresponding coupling protrusion 110. .

If the angle between the ground terminal 113 and the power supply terminal 112 is 90 degrees, a total of four terminals may be disposed in one coupling protrusion 110. In this case, the four terminals may include, for example, two ground terminals 113 and two power terminals 112, which may be alternately arranged along the circumference of the corresponding coupling protrusion 110. . As such, when a plurality of terminals are disposed around each coupling protrusion 110, the terminals except the ground terminal 113 and the power terminal 112 may be used as sensing terminals for automatically detecting whether other blocks are assembled. It may be.

The data terminal 111, the voltage terminal 112, and the ground terminal 113 disposed on each coupling protrusion 110 are respectively connected to the data terminal, the voltage terminal, and the ground terminal of the control unit 130 provided in the main block 100. Electrically connected. In addition to the control unit 130, components such as the storage unit 140, the wired communication unit 150, and the wireless communication unit 160 may be additionally disposed inside the main block 100. Components constituting the main block 100 will be described later with reference to FIG. 3.

The sensor block 200 is a block that can be assembled to the main block 100 and includes a sensor. For example, the sensor block 200 is used to detect a distance that is a temperature sensor, a humidity sensor, a 9-axis sensor for detecting vibration or movement, a magnetic sensor used for checking the opening or closing of a window or a visit, an NFC sensor, and a movement. Ultrasonic sensor, gas sensor used to check the outflow of gas, flow sensor used to check the flow of water, infrared sensor, remote control sensor, current sensor, carbon dioxide sensor used to check the air condition, used to detect ultraviolet rays Ultraviolet light sensor, and a piezo sensor used to detect ultrasonic waves or vibrations.

According to an embodiment, the sensor block 200 has a square pillar shape. The cross section of the sensor block 200 may be square or rectangular, and the height of the sensor block 200 may be variously implemented.

2, a plurality of coupling protrusions 210 are disposed on an upper surface of the sensor block 200. Each coupling protrusion 210 includes a data terminal 211, a voltage terminal 212, and a ground terminal 213.

A plurality of coupling grooves 220 are disposed on the bottom surface of the sensor block 200. The plurality of coupling grooves 220 included in the lower surface correspond to the plurality of coupling protrusions 210 included in the upper surface thereof. Like the plurality of coupling protrusions 210 included in the upper surface, the data terminal 221, the voltage terminal 222, and the ground terminal 223 are disposed in the plurality of coupling grooves 220 included in the lower surface, respectively. The data terminal 211 penetrating the center of the coupling protrusion 210 included in the upper surface is electrically connected to the data terminal 221 disposed in the center of the coupling groove 220 formed at a position corresponding to the coupling protrusion 210. Connected. Therefore, when the coupling groove 220 formed on the lower surface of the sensor block 200 is coupled to the coupling protrusion 110 formed on the upper surface of the main block 100, the

data terminals

221 and 211 and the main of the sensor block 200 are connected. The data terminals 111 of the block 100 are electrically connected to each other. Similarly, the

voltage terminals

212 and 222 of the sensor block 200 are electrically connected to the voltage terminals 112 of the main block 100, and the

ground terminals

213 and 223 of the sensor block 200 are connected to the main block. It is electrically connected to the ground terminal 113 of the (100).

The peripheral block 300 is a block that can be assembled to the main block 100 and includes a peripheral device. For example, the peripheral block 300 may include a VGA camera, an HD camera, a DC motor, a servo motor, a step motor, a light emitting device, a sound input / output device, and a battery.

According to an embodiment, the peripheral block 300 has a square pillar shape. The cross section of the peripheral block 300 may be square or rectangular, and the height of the peripheral block 300 may be variously implemented. A plurality of coupling grooves are disposed on the lower surface of the peripheral block 300. A plurality of coupling protrusions are disposed on the upper surface of the peripheral block 300. Each coupling protrusion is provided with a data terminal, a voltage terminal and a ground terminal. A plurality of coupling grooves are disposed on the lower surface of the peripheral block 300. The plurality of coupling grooves included in the lower surface correspond to the plurality of coupling protrusions included in the upper surface and their positions. Similar to the plurality of coupling protrusions included in the upper surface, the data terminal, the voltage terminal, and the ground terminal are disposed in the plurality of coupling grooves included in the lower surface, respectively. The data terminal passing through the center of the coupling protrusion included in the upper surface is in contact with the center of the coupling groove formed at a position corresponding to the coupling protrusion. Therefore, when the coupling groove formed on the lower surface of the peripheral block 300 is coupled to the coupling protrusion 110 formed on the upper surface of the main block 100, the data terminal of the peripheral block 300 and the data of the main block 100 are provided. The terminals 111 are electrically connected to each other. Likewise, the voltage terminal of the peripheral block 300 is electrically connected to the voltage terminal 112 of the main block 100, and the ground terminal of the peripheral block 300 is the ground terminal 113 of the main block 100. Is electrically connected).

In the above description, the case where the sensor block 200 and the peripheral block 300 are assembled on the main block 100 is described as an example. According to another embodiment, another sensor block 200 may be assembled on the predetermined sensor block 200, and another peripheral block 300 may be assembled on the predetermined peripheral block 300. In addition, the main block 100, the sensor block 200, and the peripheral block 300 may be stacked and assembled in order.

According to an embodiment, each of the sensor block 200 and the peripheral block 300 is assigned a unique identifier, for example, a universally unique identifier (UUID). When each block is assembled to the main block 100, the UUID assigned to each block is recognized by the main block 100. When the UUID is assigned to each block, the user can assign the same type of sensor block to the base substrate. Even if assembling several 200, the IoT service can be implemented without a problem.

3 is a diagram illustrating a configuration of the main block 100 shown in FIG. 1.

Referring to FIG. 3, the main block 100 includes a controller 130, a storage 140, a wired communication unit 150, and a wireless communication unit 160.

The storage 140 stores data and / or algorithms necessary for the main block 100 to operate. For example, store the identifier database. The identifier database contains the type of block and the identifier assigned to each block. Such storage may include non-volatile memory, volatile memory, internal memory, removable external memory, or any type of computer readable recording medium well known in the art. Examples of the external memory include an SD card (Secure Digital Card), a mini SD card, and a micro SD card.

As another example, the storage unit 140 may include algorithms and peripheral devices necessary to process data sensed by the sensor block 200 when the sensor block 200 or the peripheral block 300 is assembled to the main block 100. A drive drive or the like required to drive the block 300 may be stored.

Data stored in the storage 140 may be continuously updated. For example, when the storage unit 140 is implemented as a removable external memory, the data may be updated by replacing the external memory in which the existing data is stored with the external memory in which the new data is stored. As another example, when the storage unit 140 is implemented as something other than a removable external memory, new data may be downloaded from an external device (not shown) through a wired or wireless network, and existing data stored in the storage unit 140 may be stored in the storage unit 140. The data can be replaced with the downloaded data.

The wired communication unit 150 supports the wired communication function of the main block 100. Examples of wired communication include USB 2.0, UTP, Ethernet switch, I2C, I2S, PCM, UART, and JTAG.

The wireless communication unit 160 supports the wireless communication function of the block device 1. Wireless communication methods include Wi-Fi 802.11 b / g / n, Bluetooth, Bluetooth Low Energy (BLE), Z-Wave, ZigBee and Near Field Wireless. For example, Near Field Communication (NFC). According to an embodiment, the wireless communication unit 160 may support only some wireless communication schemes among the illustrated wireless communication schemes. In this case, a wireless communication method not supported by the wireless communication unit 160 may be supported by a communication block (not shown). For example, by assembling a communication block including a Z-Wave module and / or a communication block including a Zigbee module to the main board 100, the main board 100 may be a jet wave or a direct-wave. Can be supported.

The controller 130 connects and controls the components in the main block 100. Specifically, when a predetermined block is assembled to the main block 100, the controller 130 automatically recognizes the type of the assembled block and receives data from the recognized blocks. That is, the controller 130 may be understood to support a flag function for the sensor block 200 and the peripheral device block 300. A more detailed description thereof will be described later with reference to FIGS. 4 to 7.

In the above, the structure of the main block 100 was demonstrated with reference to FIG. 3 illustrates a case in which the main block 100 does not include a power supply unit. In this case, a power block (not shown) may be provided separately from the main block 100. The power block may have a shape similar to that of the sensor block 200 or the peripheral block 300. The power block may also include a battery, which may be replaced with another battery or charged by a charging device. When the power block is assembled (connected) to the main block 100, the power block supplies power to the main block 100, the sensor block 200 and the peripheral block 300 assembled to the main block 100. . Although not shown in FIG. 3, according to another embodiment, the main block 100 may further include a power supply unit (not shown). At this time, the power supply unit may be implemented to be charged according to the wired power communication technology or wireless power communication technology.

4 is a diagram illustrating an example of a process in which the main block 100 recognizes sensor blocks.

Prior to the description, a first sensor block having a size smaller than the size of the main block 100 is assembled on the main block 100, and a second sensor having a size smaller than the size of the first sensor block is mounted on the first sensor block. Assume that the block is assembled.

First, the main block 100 transmits an identifier request signal to the first sensor block (S410).

When the identifier request signal is received from the main block 100, the first sensor block transmits an identifier response signal including its identifier to the main block 100 (S420). In this case, the identifier response signal may further include block information of the first sensor block in addition to the identifier of the first sensor block. Here, the block information may include, for example, types of sensors included in the first sensor block, arrangement information of the coupling protrusions included in the first sensor block, colors of the first sensor block, and the like. However, the block information is not necessarily limited to those illustrated.

Thereafter, the first sensor block transmits the identifier request signal received from the main block 100 to the second sensor block (S430). According to another embodiment, the first sensor block may generate an identifier request signal and transmit it to the second sensor block.

Thereafter, when the identifier request signal is received from the main block 100 again (S450), the first sensor block waits until an identifier response signal and / or a last flag signal are received from the second sensor block.

On the other hand, the second sensor block receiving the identifier request signal from the first sensor block determines whether it is the last block (S440). According to an embodiment of the present disclosure, when there is no other block assembled on the upper surface of the second sensor block, the second sensor block may determine that the second sensor block is the last block. According to another embodiment, after transmitting the identifier request signal received from the first sensor block, if the identifier response signal is not received within a predetermined time, the second sensor block may determine that the second sensor block is the last block.

As such, when it is determined that the second sensor block is the last block, the second sensor block transmits an identifier response signal including a last flag signal and its identifier to the first sensor block that it is the last block ( S460). In this case, the last flag signal may be a signal separate from the identifier response signal, or may be included in the identifier response signal. In addition, the identifier response signal may further include block information of the second sensor block in addition to the identifier of the second sensor block.

The first sensor block transmits the identifier response signal and the last flag signal received from the second sensor block to the main block 100.

As a result, the main block 100 may include the first sensor block and the second sensor based on the identifier response signal including the identifier of the first sensor block, the identifier response signal including the identifier of the second sensor block, and the last flag signal. The block may be recognized (S480).

On the other hand, the above-described process is performed for each of the coupling protrusions included in the main block 100, respectively. Therefore, if the number and type of signals received through the coupling protrusions of the main block 100 are determined, it is possible to determine what kind of sensors are stacked in each coupling protrusion of the main block 100. That is, the main block 100 may obtain information on the three-dimensional coupling structure between the respective sensor blocks based on the identifier response signal and the last place signal received from the first sensor block.

In the above, an example of a process in which the main block 100 recognizes the sensor block has been described with reference to FIG. 4. Referring to FIG. 4, the main block 100 may be understood to periodically generate and transmit an identifier request signal in order to recognize sensor blocks stacked and assembled in the main block 100.

5 is a diagram illustrating another example of a process in which the main block 100 recognizes sensor blocks.

First, the main block 100 generates an identifier request signal and transmits it to the first sensor block (S510).

When the identifier request signal is received from the main block 100, the first sensor block transmits an identifier response signal including its identifier to the main block 100 (S520).

When the identifier response signal including the identifier of the first sensor is received from the first sensor block, the main block 100 generates a new identifier request signal and transmits it to the first sensor block again (S530).

When the identifier request signal is received from the main block 100, the first sensor block transmits the identifier request signal received from the main block 100 to the second sensor block (S540). That is, the first sensor block transmits the identifier request signal received from the main block 100 to the second sensor block instead of generating an identifier response signal with respect to the identifier request signal received from the main block 100. This is because the identifier response signal including the identifier of the first sensor block is already transmitted to the main block 100.

When the identifier request signal is received from the first sensor block, the second sensor block determines whether it is the last block (S550). If it is determined that the second sensor block is the last block, the second sensor block generates an identifier response signal including its identifier and a last flag signal indicating that it is the last block and transmits it to the first sensor block ( S560).

When the identifier response signal and the last flag signal including the identifier of the second sensor block are received from the second sensor block, the first sensor block receives the identifier response signal and the last flag signal received from the second sensor block. Transfer to (S570).

As a result, the main block 100 may include the first sensor block and the second sensor based on the identifier response signal including the identifier of the first sensor block, the identifier response signal including the identifier of the second sensor block, and the last flag signal. The block may be recognized (S580).

In the above, another example of the process in which the main block 100 recognizes the sensor block has been described with reference to FIG. 5. Referring to FIG. 5, it may be understood that the main block 100 sequentially recognizes the sensor blocks stacked close to the main block 100 by sequentially transmitting the identifier request signal.

FIG. 6 is a diagram illustrating another example of a process in which the main block 100 recognizes sensor blocks.

Prior to the description, a first sensor block having a size smaller than the size of the main block 100 is assembled on the main block 100, and a second sensor having a size smaller than the size of the first sensor block is mounted on the first sensor block. Assume that the block is assembled. In addition, it is assumed that the terminal block having the same size as that of the second sensor block is assembled on the second sensor block.

First, the main block 100 transmits an identifier request signal to the first sensor block (S610).

The first sensor block transmits the identifier request signal received from the main block 100 to the second sensor block (S620).

The second sensor block transmits the identifier request signal received from the first sensor block to the end block (S630).

The terminal block receiving the identifier request signal from the second sensor block transmits an identifier response signal including its identifier to the second sensor block (S640).

The second sensor block adds its identifier to the identifier response signal received from the end block (S650). In operation S660, an identifier response signal having its own identifier added thereto is transmitted to the first sensor block.

The first sensor block adds its identifier to the identifier response signal received from the second sensor block (S670). In operation S680, the identifier response signal to which the own identifier is added is transmitted to the main block 100.

As a result, the main block 100 may recognize the first sensor block and the second sensor block based on the identifier response signal received from the first sensor block (S690).

On the other hand, the above-described process is performed for each of the coupling protrusions included in the main block 100, respectively. Therefore, if the number and order of identifiers included in the identifier response signal received through each coupling protrusion of the main block 100 are known, a certain kind of sensor may be divided into several layers in each coupling protrusion of the main block 100. It is possible to determine whether they are stacked. That is, the main block 100 can obtain information about the three-dimensional coupling structure between the main block 100 and the respective sensor blocks.

In the above, another example of the process in which the main block 100 recognizes the sensor block has been described with reference to FIG. 6. Referring to FIG. 6, it may be understood that the main block 100 generates and transmits an identifier request signal only once in order to recognize sensor blocks stacked and assembled in the main block 100.

FIG. 7 is a diagram illustrating a data communication process between the main block 100 and the sensor blocks shown in FIG. 1.

Prior to the description, it is assumed that the first sensor block is assembled on the main block 100 and the second sensor block is assembled on the first sensor block. When the first sensor block or the second sensor block attempts to transmit data to the main block 100 while the main block 100 and the respective sensor blocks are in this state, the first sensor block or the second sensor block generates an interrupt signal. Let's do it. In this case, an interrupt signal may be preferentially generated in the sensor block disposed closer to the main block 100.

Specifically, when data is to be transmitted, the first sensor block generates an interrupt signal and transmits the interrupt signal to the main block 100 (S710).

The main block 100 receiving the interrupt signal from the first sensor block generates and transmits a data request signal for requesting data of the first sensor block to the first sensor block (S720).

The first sensor block receiving the data request signal from the main block 100 generates a data response signal including data measured by the first sensor block and transmits the data response signal to the main block 100 (S730).

On the other hand, when the second sensor block intends to transmit data, the second sensor block generates an interrupt signal and transmits the interrupt signal to the first sensor block (S740). In FIG. 7, step S740 is shown to be performed after step S730, but step S740 may be performed between steps S720 and S730.

The first sensor block receiving the interrupt signal from the second sensor block generates a data request signal and transmits the data request signal to the first sensor block (S750).

Thereafter, the first sensor block transmits the interrupt signal received from the second sensor block to the main block 100 (S760).

Meanwhile, the second sensor block receiving the data request signal from the first sensor block generates a data response signal including data measured by the second sensor block and transmits the data response signal to the first sensor block (S770).

The main block 100 receiving the interrupt signal of the second sensor block from the first sensor block generates a data request signal for requesting data of the second sensor block and transmits the data request signal to the first sensor block (S780).

When the data request signal for requesting data of the second sensor block is received from the main block 100, the first sensor block transmits the data response signal received from the second sensor block to the main block 100 (S790).

Referring to FIG. 7, while data is being transmitted from the first sensor block to the main block 100, even if an interrupt signal generated in the second sensor block is received by the first sensor block, the first sensor block may have its own data. It can be seen that it waits until the transmission is completed and then communicates with the second sensor block.

The embodiments of the present invention have been described above.
