Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise. Also, the terms "part," "module," and the like, which are described in the specification, refer to a unit for processing at least one function or operation, and may be implemented by hardware or software or a combination of hardware and software.

In the embodiment of the present invention, a device and a wiring pattern included in a floor tile can be configured so that it can be applied to the floor of an actual indoor / outdoor architectural space, and by simply joining and installing these tiles without a separate wiring or device, Smart flooring system using new smart floor tiles that can be used for applications such as smart home, smart building, and smart city by detecting location and walking pattern are provided. Here, a plurality of smart floor tiles are used to constitute a smart floor according to an embodiment of the present invention.

The I2C (Inter-Integrated Circuit) communication method employed in the embodiment of the present invention is a communication method in which a plurality of slave devices 1 and 2 communicate with a plurality of master devices 3 and 4 And is designed for close range communication between elements of an electronic system. The I2C communication is composed of one SDA 5 as a line for exchanging data and a SCL 6 as a clock line for synchronization of transmission and reception timings and includes one or more masters 3 and 4 and one or more And slaves (1, 2). If the master (3,4) and the slave devices (1,2) such as transducers or actuators contain separate lines for power supply (7) and ground (8), then all four lines will have one I2C communication unit Respectively. In addition, since both the master 3 and 4 or the slaves 1 and 2 use the operation of transmitting or receiving data, the SDA 5 line uses both the input and the output, A pull-up resistor 9 is used.

In the embodiment of the present invention, up to now, 128 transducers can be serially connected to two stranded cable lines allowed by the I 2 C (Inter-Integrated Circuit) communication method, and selected transducers are connected in series By connecting these cables to the master unit, including the power supply and ground wires, it dramatically reduces the complexity, effort and expense of cabling from the one-to-one connection between the transducer and the processing unit, as in most existing smart floor systems .

For example, in the case of a smart floor tile in which the acceleration sensor is embedded in the upper center, the acceleration sensor is concealed in the center of the tile as an inherent form, and each sensor is equipped with SDA (Serial Data), SCL (Serial Clock) , Ground, and power supply lines are connected in series. Cables that make up a serial bus can be built into each tile and connected at the ends of the tile to each other during wiring, and then joint tiles can be attached to the floor using conventional floor construction using joint mortars. In this case, the sensor in the center of each tile corresponding to the slave sensor node and the cable connecting them in series can easily cover the irregular arrangement of the entire floor space with simple tie-line connector connection and construction without additional wiring, It is possible to construct a floor.

The connection lines of each tile are again connected to one bus line and finally connected to the master device, which is then connected to a control device (such as a computer or an embedded board) which controls the smart floor system as a whole, The system configuration for the application can be easily completed.

On the other hand, if the number of transducers connected to the master device exceeds 128 and all the master devices can not be connected, another master device is set and the remaining transducers are connected to the master device, The master unit can be used to convert a relatively large floor space to a smart floor. In this case, a plurality of master devices need to be connected to the control device.

Another important point in the embodiment of the present invention in addition to the dramatic economical and simplification of the smart floor construction and construction is that it has a separate lower slit for receiving cables finished with insulating and insulating materials at the bottom of the tile, Even if it is sensitive to heat or electromagnetic field, it provides upper and lower shield to protect it.

In this way, reliability and stability of the transducer signal are ensured. In addition, when the floor heating tile floor heating system is used as a domestic apartment, considering the fact that the floor tile should be a thermal conductive body, the wiring and the transducer are protected from heat, This will overcome the conflicts caused by differences in physical requirements between the two.

On the other hand, the sensor to be mounted on the smart floor tile is a sensor that measures the pressure by using internal displacement or piezoelectric phenomenon such as FSR (Force Sensitive Resistor), a load cell or a fiber optic sensor in most existing research and development efforts However, in the case of a pressure sensor, the range of the pressure acting is limited, the fluctuation of the measurement value is severe according to various conditions, the correction is required from time to time, and if the continuous load is applied, the sensitivity of the sensor value becomes dull after the load disappears And the like.

Therefore, in the embodiment of the present invention, various kinds of sensors capable of detecting the position and walking pattern of a resident using heat or vibration, such as an infrared sensor, a motion sensor, an acceleration sensor, a sound sensor, (Exposed top of tile), 2) hidden under the surface of the floor tile (concealed top of the tile), or 3) inside the floor tile It is produced by joining to the floor tile from the manufacturing since it is manufactured. It also produces the LED, miniature speaker, vibrator and other actuators that can generate light, sound, vibration and so on, Eliminating the need for transducer installation and wiring.

These transducers are the same transducer with the unique address given to them at the time of manufacture, but they can be used to make all the transducers in the transducer grid have unique identification IDs, A memory is provided and an extended address is given through the master device to give a unique address to all the transducers in the grid so that it is possible to distinguish which transducer the master device is coming from when generating the signal.

Hereinafter, a smart floor tile according to an embodiment of the present invention will be described in detail with reference to the drawings.

2, 3, 4 and 5, a smart floor tile 100 according to an embodiment of the present invention includes tile connectors 110 and 111, communication cables 120 and 121, A cable tray 140, a branch connector 150, and a transducer connecting cable 160. The cable tray 140,

First, the smart floor tile 100 is made of a general tile material such as ceramic, marble, wood panel, synthetic material, etc., and a transducer module 130 is mounted at the center thereof.

The tile connectors 110 and 111 are used for wire bonding with other smart floor tiles. Specifically, the tile connectors 110 and 111 are connected to four signal lines (SDA, SCL, ground, and power lines) according to the I2C communication method according to an embodiment of the present invention. It is used to interconnect cables with other smart floor tiles. The smart floor tile connection method through the tile connectors 110 and 111 can be accomplished by various methods. For example, a male or female connector type may be used between interconnected smart floor tiles, or may be interconnected using separate tile coupling connectors (shown later) between smart floor tiles. This will be explained later.

The transducer module 130 includes sensors for calculating external stimuli such as light, sound, and vibration and actuators (e.g., LEDs, speakers, vibrators, etc.) actuators, for example.

The transducer module 130 is coupled to the body of the tile 100, but is mounted to be removable or replaceable if necessary.

The sensor mounted in the transducer module 130 may be a sensor for detecting position, gait pattern, a motion sensor, an infrared sensor, a sound sensor, a pressure sensor, an acceleration sensor, etc., Sensors, and conversely, actuators that produce stimuli in the external environment include LEDs, small speakers, buzzer, and vibrator.

Meanwhile, the transducers installed in one transducer module 130 may have one or more than one transducers. For example, in order to realize a scenario such as a nighttime indoor / outdoor walking path presentation rather than a simple user's position sensing , Sensors and LEDs that detect the user's physical presence and location within a specific tile, and actuators that indicate that the user is detected in a particular tile, such as a buzzer. In this case, the sensors and actuators mounted in the transducer module 130 may be interconnected through signal lines corresponding to the I 2 C communication method inside the transducer module 130.

The communication cables 120 and 121 are used to connect the four signal lines of the tile connectors 110 and 111 and the branch connector 150.

The cable tray 140 is inserted into the bottom of the tile 100 in a straight or L-shaped groove and closed with a cover for insulation and insulation so that the tile connectors 110 and 111, the communication cables 120 and 121, And performs insulation from the floor and insulation from the ducer module 130.

The branch connector 150 is used to provide four signal lines of the communication cables 120 and 121 to the outside. Specifically, the branch connector 150 is used to provide the signal lines of the communication cables 120 and 121 to the transducer module 130.

The transducer connecting cable 160 is used to connect the four signal lines of the branch connector 150 to the transducer module 130. [

Thus, the transducer module 130 is connected to an external master or other smart floor tiles 100 (not shown) through the transducer connecting cable 145, the branch connector 150, the communication cables 120, 121 and the tile connectors 110, Can be transmitted.

In the above description, only at least one sensor and at least one actuator are mounted together in the transducer module 130, but the technical scope of the present invention is not limited thereto, A plurality of transducer modules 130 may be mounted.

6 is a view showing an example in which two transducer modules are mounted on a smart floor tile according to an embodiment of the present invention.

Referring to FIG. 6, two transducer modules 130 and 130 'are mounted inside the smart floor tile 100. Each of these two transducer modules 130, 130 'may also be equipped with at least one sensor and / or at least one actuator.

The two transducer modules 130 and 130 'are interconnected through a communication cable 123 to connect the four signal lines corresponding to the I2C communication method between the transducer modules 130 and 130'.

In the above description, the tile connectors 110 and 111 in the smart floor tile 100 are symmetrical with respect to the center of the tile 100, that is, with respect to the transducer module 130, The tiles 100 are disposed at both ends of the tiles 100. However, the tiles 100 may vary depending on the connection method of the tiles 100. Alternatively, the smart floor tile 100 according to the embodiment of the present invention may form the tile connectors 110 and 111 as shown in FIGS. 7A, 7B, 7C and 7D. Particularly, in the case of the square tile 100, when the tile connectors 110 and 111 are made of the L-shaped connector with reference to the transducer module 130, the direction of the tile 100 may be rotated When the tiles 100 are arranged in the form of (a), (b), (c) or (d) and then connected to each other, an L-shaped arrangement which can be applied to any case can be formed.

Meanwhile, the cable tray 140 is assembled to the lower portion of the tile 100 in the process of manufacturing the tile 100, and is embedded in the tile with the branch connector 150 attached to the center thereof.

FIG. 8 is a diagram showing a specific configuration in which a transducer module 130 according to an embodiment of the present invention is coupled to a smart floor tile 100. FIG.

Referring to FIG. 8, a transducer module 130 according to an embodiment of the present invention includes a transducer 131, a transducer lead 132, and an insulator 133.

Depending on the type of the transducer 131, the type of the head portion exposed on the surface of the transducer module 130, such as an infrared sensor or an LED, a sensor for detecting vibration or shaking, such as a sound sound sensor or an acceleration sensor, Such as in the transducer module 130, as shown in FIG.

The transducer module 130 can be fabricated in the form of a square or circular stopper that retains the same finish as the surface of the tile 100, with a transducer wrapped in the insulator 133, have.

The transducer module 130 is also inserted into the pre-drilled opening in the tile 100 and secured by an adhesive material 134 for engagement with the tile 100. The leads 132 under the transducer module 130 are inserted into the transducer connector 170 for connection with the transducer connecting cable 160 coming out from the branch connector 170 located under the tile 100 Loses.

The configuration and assembly of the smart floor tile 100 related modules basically involves bake the material at high temperatures, sometimes through separation of the electronic component units such as the tile 100 itself and the transducer module 130 coupled thereto A maintenance advantage of preventing the collision of the manufacturing conditions of the tiles 100 in the manufacturing process of the tiles 100 and the replacement of the broken transducers 131 in the tiles 100 instead of replacing the entire tiles 100 when necessary . Here, when the transducer module 130 of the tile 100 breaks down or a problem occurs in the connector for connection, the adjacent tile joint joint of each tile 10 may be replaced with a conventional joint joint mortar Alternatively, it can be easily removed from the tile body after the tile 100 has been removed, such as opaque silicon or synthetic material, and the connector or its connection in the tile 100 or the embedded or concealed portion of the transducer 130 It is made of structure and material that can be easily separated.

Meanwhile, in the smart floor system according to the embodiment of the present invention, an I2C communication method is used between a master device controlling an entire system and a transducer 131 installed in each tile 100. [

As is well known, the I2C communication method has two connections: serial clock (SCL) and serial data (SDA) between low-speed peripherals. There are SCLs that provide clock signals and SDLs for data transfers, and a master device is connected to one side of the I2C bus and several other devices (slaves, slave devices) that are moved by information are connected to the other side. At this time, there is only one master device, and the slave device can have a unique address of 7 bits, so that a maximum of 128 slave devices can be connected. The advantage of an I2C connection is that it can serialize up to 128 devices on a bus extending from a single master, dramatically reducing the complexity and hassle of cabling resulting from the unnecessary one-to-one connection between slave and master to be.

In general, the address used to designate a device to be a slave device in the I2C communication scheme is represented by 7 bits or 10 bits, and most devices use a 7-bit address in order to use a 7-bit address If so, the number of devices that the master device can assign is limited to 128.

Most of the transducers connected through the I2C communication method are different types of transducers having unique addresses given from hardware devices and manufacturers that are compatible with the I2C communication method. However, if a plurality of transducers are used In the case of a transducer grid of a kind, it is virtually impossible to distinguish signals from transducers that have been given the same address by the manufacturer.

However, the device address can be specified by the device manufacturer or by using the external pin of the device. For packages with a small number of pins, the upper bits of the address are fixed and only the lower bits are possible.

In addition, a transducer grid configuration using I2C communication requires a computer (PC) or an embedded board, which requires resources for grounding and power supply and is connected to the master device to receive and process signals from the transducers.

The most common method of connecting a plurality of transducer nodes to the I2C is a serial bus connection (hereinafter referred to as " serial bus connection ") in which each of the smart floor tiles 100, Method.

Through the serial bus connection method, a total of 128 transducers are connected to one master device (microcontroller 200 such as Arduino), and if the number of transducers exceeds 128, And the master devices 200 may be connected to a controller (a computer or an embedded board) 300 that controls the smart floor system via a USB or the like.

Another method of connecting the transducers mounted on the smart floor tiles 100 according to the I2C communication scheme is to connect the transducers of the smart floor tiles 100 to each of the smart floor tiles 100, Line hybrid connection that connects the end of these columns to the I2C main bus.

The advantage of the serial-parallel hybrid connection scheme is that the length of the cable from the master device 200 to all the slave devices can be reduced, thereby reducing communication efficiency, error reduction, and material cost.

The control device 300 shown in FIGS. 9 and 10 includes a plurality of slave devices 100, a plurality of transducers 131 connected to the master device 200 via the I2C communication method through the master device 200, Lt; / RTI > That is, the control device 300 recognizes the situation of the user located on the smart floor system through the plurality of slave devices 100 and performs control corresponding thereto. That is, it can perform control for applications such as a smart home, a smart office, a smart square, and a smart city.

Meanwhile, in order to connect the smart floor tile 100 according to the method shown in FIGS. 9 and 10, the tile connecting connector 400 is used as shown in FIG. 11 in the embodiment of the present invention. Two tiles 100 can be coupled through the tile coupling connector 400 by coupling one tile 100 to one side of the tile coupling connector 400 and the other tile 100 to the other side. have. Here, as shown in FIG. 7, when the square tile 100 having the L-shaped connector is rotated and used, the directions of the signal lines of the connectors between the two tiles 100 may be different from each other. In this case, a tile-joining connector 400 is used which allows the signal lines on both sides to be coupled in opposite directions.

In addition, the current I2C communication system performs bidirectional data communication through 7-bit addresses, that is, addresses assigned to 128 devices. Generally, it is common that different transducers in a production department are given different address values through the manufacturer. In the case of the same type of transducer, the lower 2-3 bits of the address can be varied as needed, In this case, the transducer has three address pins for connecting to the master device 200 via the I2C interface so that up to eight homologous transducers can be connected to one I2C bus without address conflicts.

In the embodiment of the present invention, when a kind of transducer grid needs to be formed through an array of the same kinds of transducers, it is possible to use an address-based communication format between the master device 200 and the slave device 100 on this I2C communication It is necessary to overcome the limitations of the smart floor tiles 100. In the case of the transducer 131 used in the smart floor tiles 100, a plurality of homogeneous transducers are given separate addresses from the time of manufacture.

In addition, the slave device address differentiation method of other homogeneous transducers further enlarges the address variation range available from the user to 2-3 bits, ultimately enabling the user to arbitrarily designate the address of each slave device .

In the embodiment of the present invention, it is possible to construct and operate a smart tile grid composed of homogeneous transducers in at least one of the two modes.

9 and 10, an application server (not shown) for providing other services or applications, for example, applications such as user position sensing, fall detection, walking path guide, game, So that it can interwork with the smart floor system according to the embodiment of the present invention.

The smart floor system for recognizing the user's position and the gait pattern applicable to a smart home, a smart office, a smart square, or a smart city can be constructed simply, robustly, and economically in the same manner of constructing a general floor tile through embodiments of the present invention A new way of operating can be realized. In other words, the smart floor system will be opened to commercialization.

In addition, the smart floor system according to the embodiment of the present invention can provide indoors user position recognition that is essential for smart building and smart city applications by constructing a simple tile combining method that eliminates the need for wiring based on the I2C communication method. It is possible to identify the person's identity, health status, mood state and so on through the gait pattern check. In the case of the elderly or the disabled, it is necessary to detect an accident such as a pre- It can be used for a variety of applications such as providing a mechanism, detecting an intruder of an outsider, tracking the usage pattern of indoor and outdoor people and information utilization.

In addition, if the occupant observes and analyzes gait patterns in a smart home or an elderly residence to detect the health condition or abnormal behavior of a resident, or installs an LED as a slave device instead of a transducer, . In museums and exhibition halls, it is possible to grasp view lines of visitors, or conversely, to induce blinking of LEDs in appropriate viewing circles. In the case of visually impaired persons, guidance on moving routes through sound or vibration and warnings .

It is also possible to detect a position where the user's foot is tilted and thereby to enable a kind of interactive game by driving a display or a speaker built in the floor tile.

Ultimately, practically commercialization of a smart floor system is possible by the embodiment of the present invention.
