Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.
First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.
Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection fluorescent light sensor, a mirror reflection fluorescent light sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.
On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .
The touch sensor senses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, do.
For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.
Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.
On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.
The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.
The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.
The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

Hereinafter, a method of installing the sensor 220 (or the hub 200) so that the sensor 220 and the hub 200 can perform wireless communication will be described in detail with reference to the accompanying drawings.
In the past, a professional article installer has visited the hub 200 and installed the sensor 220 in an appropriate position, and tried to connect the hub 200 and the sensor 220 in a wireless communication manner. However, if the installation is not completed (i.e., fails) to allow wireless communication in a state where the installation is completed, the installer may move the installed sensor 220 or hub 200 away from the installed location, After the installation is completed, the connection is attempted again to determine whether wireless communication between the hub 200 and the sensor 220 is possible. When the wireless communication is established, the installation of the sensor 220 and the hub 200 is completed.
If an error occurs in the communication between the installed hub 200 and the sensor 220 after the installation professional is finished after the installation is completed, the installation professional should visit again and repeat the procedure described above.
Therefore, conventionally, the installation time is long, the frequency of occurrence of the communication error is high, and when the error occurs, the article must be visited again, which leads to a problem of wasting human / material / temporal waste.
The system constituting the Internet of objects related to the present invention can solve the above problems.
FIG. 3 is a flowchart illustrating an exemplary control method of the present invention, and FIGS. 4A, 4B, and 4C are conceptual diagrams illustrating a control method illustrated in FIG.
FIG. 3 shows a flow chart of a control method of a mobile terminal with an emphasis on the mobile terminal.
Referring to FIG. 3, first, in the present invention, when a hub and a sensor are connected to each other so as to allow wireless communication within a predetermined distance from the hub 200, first screen information indicating a connection state between the hub and the sensor is moved A step of outputting to the touch screen of the terminal proceeds (S310).
Before the sensor 220 is installed (or attached), the hub 200 and the sensor 220 are connected to each other so that wireless communication is possible. That is, the hub 200 may be connected to allow wireless communication with the sensor 220 existing within a predetermined distance. The predetermined distance is a distance (or area or space) in which wireless communication between the sensor 220 and the hub 200 is possible with respect to the hub 200. This distance is determined by the distance between the hub 200 and the sensor 220 The performance of the communication module provided, or the type of communication technology used for the communication between them. If the wireless communication technology between the hub 200 and the sensor 220 is Zigbee or Z-Wave, the predetermined distance may be about 10 m.
Means that the hub 200 and the sensor 220 are connected to each other so as to allow wireless communication within a predetermined distance from the hub 200 so that the distance between the hub 200 and the sensor 220 And may mean wirelessly connected to enable communication.
When the hub 200 and the sensor 220 are connected so as to allow wireless communication within a predetermined distance, it is preferable that an obstacle of a type affecting wireless communication does not exist between the hub 200 and the sensor 220 .
The connection between the hub 200 and the sensor 220 may be performed in various manners. For example, the hub 200 may have a button associated with a function of searching for a sensor. When the button is selected by the user, the hub 200 can transmit a signal for searching for a sensor existing within a predetermined distance through the communication module (or the router 210). Thereafter, when a response signal is received from the specific sensor according to the response of the sensor existing within the predetermined distance, the hub 200 and the specific sensor can be connected to enable wireless communication.
Alternatively, when the button of the sensor 220 is selected by the user, the hub 200 existing within the predetermined distance may be provided with a button associated with the function of transmitting the specific signal. And the sensor 220 may be interconnected to enable wireless communication.
As another example, the hub 200 and the sensor 220, which are within the predetermined distance (or the predetermined space A), may be connected to each other to be capable of wireless communication with each other under the control of the mobile terminal 100.
As shown in FIG. 4A, the hub 200 can search for a sensor that exists within a predetermined distance (or predetermined space A). The search may be performed based on a button provided on the hub 200, a search function associated with the search function, or a user control command applied to the mobile terminal. The hub 200 may transmit information related to a sensor (detected sensor) existing within the predetermined distance to the mobile terminal 100 through the router 210 (or a communication module).
Although FIG. 4A shows that the mobile terminal 100 exists within a predetermined distance based on the hub 200, the mobile terminal 100 does not necessarily exist within a predetermined distance.
The controller 180 of the mobile terminal 100 may output information related to the received sensor to the touch screen 151 as shown in FIG. Here, when there are a plurality of searched sensors, the touch screen 151 may display information related to a plurality of sensors.
4A, when the controller 180 of the mobile terminal 100 selects one of the information related to the sensor output from the touch screen 151, Information related to the selected sensor may be transmitted to the hub 200 through the wireless communication unit 110 so that the sensor 220 corresponding to the information and the hub 200 are connected to enable wireless communication.
The hub 200 receiving the information related to the selected sensor may further include a sensor 220 corresponding to information related to the sensor selected on the touch screen 151 of the mobile terminal, And wireless communication can be established through the communication module to enable wireless communication.
When the hub 200 and the sensor 220 are connected to each other so as to allow wireless communication within the predetermined distance A, the hub 200 is connected to the sensor 220 and the hub 200, May be transmitted to the mobile terminal 100 via the router 210 (or communication module).
The control unit 180 of the mobile terminal 100 then receives the first screen information 400a indicating the connection status between the hub 200 and the sensor 220 based on the received information related to the connection status The touch screen 151 can be controlled to be displayed.
4A, the control unit 180 controls the connection of the hub 200 and the sensor 220 to the hub 200 from the hub 200 through the wireless communication unit 110. That is, The first screen information 400a indicating the connection status can be output to the touch screen 151 based on the information related to the connection status.
Here, the connection state is a state in which the data (or packet) is transmitted from the sensor 200 to the sensor 220 from a signal strength transmitted and received between the hub 200 and the sensor 220, And a return time (e.g., Tima of Flight, ToF).
In the drawings of the present specification, it is shown that the connection state is signal strength. However, the present invention is not limited to this, and the connection state may be the time ToF.
Thereafter, in the present invention, in a state in which the hub 200 and the sensor 220 are connected, a variable connection state can be reflected on the first screen information and displayed by changing the relative distance between the hub and the sensor (S320).
Specifically, when the first screen information 400a is output to the mobile terminal (that is, when the hub 200 and the sensor 220 are connected so as to allow wireless communication), the user can move the sensor 220 to an appropriate position (Or installed) with the sensor 220. As shown in FIG. The relative distance between the sensor 220 and the hub 200 is changed by the movement (i.e., by an external force).
The connection state between the hub 200 and the sensor 220 may vary (or may vary) based on the change in the relative distance. For example, if the sensor 220 is moved away from the hub 200 by an external force (or by movement) while the hub 200 and the sensor 220 are connected, at least one of the signal strength and the time One can be changed.
For example, the signal strength may be weakened as the relative distance between the sensor 220 and the hub 200 increases. Also, the time may be longer as the relative distance between the sensor 220 and the hub 200 is increased.
The hub 200 may transmit the information related to the connection status periodically or at predetermined time intervals or in real time to the mobile terminal 100.
The control unit 180 of the mobile terminal 100 determines a variable connection state between the hub 200 and the sensor 220 based on information related to the connection state received from the hub 200, It can be reflected on the information 400a and displayed.
4B, when the relative distance between the hub 200 and the sensor 220 is changed by an external force, the control unit 180 determines that the relative distance between the hub 200 and the sensor 220 The first screen information 400a may be controlled such that at least one of the changed signal intensity and the changed time is reflected.
For example, when the sensor 220 and the hub 200 are separated from each other, the signal strength between the sensor 220 and the hub 200 may be weakened, as shown in FIG. 4B, (b).
The user can grasp (continuously) in real time whether or not the communication between the hub 200 and the sensor 220 is smooth using the screen information indicating the connection status displayed on the touch screen 151 of the mobile terminal 100 .
Thereafter, in the present invention, if the connection state satisfies the predetermined condition, the step of outputting the second screen information linked to the condition to the touch screen 151 of the mobile terminal proceeds (S330).
The predetermined condition may mean a condition in which the connection state between the hub 200 and the sensor 220 is not smooth. For example, the preset condition may be that the signal strength, which is one of the connection states, falls below a preset strength (or a reference strength, a specific strength, or a threshold value) A reference time, a specific time, or a critical time).
For example, if the relative distance between the hub 200 and the sensor 220 is too great, or if there is an obstacle between the hub 200 and the sensor 220, for example, The data (or packet) transmission / reception between the hub 200 and the sensor 220 may not be performed smoothly.
The control unit 180 of the mobile terminal 100 may determine the connection state between the hub 200 and the sensor 220 based on the information related to the connection state received from the hub 200. [
The control unit 180 may output the second screen information associated with the condition to the touch screen 151 if the connection status corresponds to the predetermined condition.
4C, if the signal strength of the connection state becomes weaker than a predetermined strength, or the time is longer than the predetermined time, the second screen information 400b may be output to the touch screen 151 as shown in FIG.
The second screen information 400b may include information for guiding the movement of the sensor 220, for example. In other words, the second screen information 400b may include information indicating that the communication state between the hub 200 and the sensor 220 (i.e., the sensor being moved by the user) is not smooth.
The second screen information 400b may be output to the touch screen 151 instead of the first screen information 400a or may be superimposed on the first screen information 400a. Alternatively, the second screen information 400b may be output to a portion of the first screen information 400a in a state in which the first screen information 400a is displayed.
The second screen information 400b may include a graphic object (for example, 'remeasurement') associated with the function of re-outputting the first screen information 400a. The controller 180 may switch the second screen information 400b to the first screen information 400a when a touch is applied to the graphic object.
As another example, the connection state between the hub 200 and the sensor 220 can be smooth again by moving the sensor 220 after the second screen information 400b is output (i.e., The predetermined condition may not be satisfied).
When the connection status is restored not to satisfy the predetermined condition and the information related to the connection status is received from the hub 200 (i.e., the connection status between the hub 200 and the sensor 220 from the hub 200) The control unit 180 switches the second screen information 400b to the first screen information 400a based on the reception of the information, if the information indicating that the set condition is not satisfied can do. In this case, the first screen information 400a may reflect the connection state between the sensor 220 and the hub 200 that does not satisfy the predetermined condition (i.e., current).
With this configuration, the present invention provides a user interface that determines whether the communication state between the sensor and the hub is smooth before the user installs the sensor, and informs the user when the communication state is not smooth .
Thus, the present invention can minimize the installation time and significantly reduce the communication error rate.
3 to 4C, the sensor is moved in a state in which the hub and the sensor are connected so as to enable wireless communication, and communication is smoothly performed between the sensor and the hub in a proper place for the sensor to be installed. A user interface can be provided.
Hereinafter, a method of installing a sensor will be described in more detail with reference to the accompanying drawings.
5 is a conceptual diagram for explaining a method of installing a sensor related to the present invention.
As shown in FIG. 5A, the sensor 220 may be provided with a button for transmitting an attachment completion signal to the hub 200 (or the mobile terminal 100). That is, the sensor 220 may include a button for transmitting an attachment completion signal to the hub 200. If the button is selected (or pushed) by the user after the sensor is attached to the location, the sensor 220 may transmit the attachment completion signal to the hub 200 via the communication module.
The hub 200 may transmit the received attachment completion signal to the router 220 in response to the button being selected at the sensor 220 (or based on the attachment completion signal being received from the sensor 220) To the mobile terminal 100 through the communication module 210 (or the communication module). At this time, if the connection state between the sensor 220 and the hub 200 does not satisfy the predetermined condition (or the signal strength is greater than a predetermined strength or the time ToF is shorter than the predetermined strength) If the connection time is shorter than the set time, that is, if the connection state is smooth, the mobile terminal 100 can transmit the attachment completion signal.
5 (b), the controller 180 of the mobile terminal 100 that has received the attachment completion signal determines that the connection completion signal does not satisfy the predetermined condition The third screen information 400c indicating that the attachment of the sensor 220 is completed can be output to the touch screen 151 based on the received information.
As shown in FIG. 5 (b), the third screen information 400c may include information for inquiring (confirming or requesting) whether to install the sensor. The control unit 180 may transmit an installation completion signal to the hub 200 when a graphic object (for example, YES) associated with the function of transmitting the installation completion signal is touched.
In this case, the hub 200 can confirm that the mounting and installation of the sensor 220 is completed based on the reception of the installation completion signal from the mobile terminal 100, and update the routing table. The contents related to the routing will be described later in more detail with reference to FIG. 6 and FIG.
Through such a configuration, the present invention can remarkably reduce the communication error rate by completing the installation of the sensor while the connection state (communication state) between the sensor and the hub is smooth.

As described above, the hub 200 and the sensor 220b may be connected so as to allow wireless communication within a predetermined distance.
6 (a), when the relative distance between the sensor 220b and the hub 200 is changed (for example, by a distance) due to an external force, the connection state can be changed .
If the connection state meets a predetermined condition (for example, the signal strength between the sensor 220b and the hub 200 becomes weaker than a predetermined strength, or data is transmitted / received between the sensor 220b and the hub 200) The control unit 180 transmits information 610a inquiring (confirming or requesting) whether to perform routing instead of the second screen information to the touch screen 151 As shown in Fig.
The information 610a may be superimposed on the first screen information 600 indicating the connection state between the hub 200 and the sensor 220b or may be displayed on at least a part of the first screen information 600 have.
The control unit 180 transmits a control command to the hub 200 to control the routing of the user control command to the hub 200 using the information 610a, 200).
The control unit 180 of the mobile terminal 100 may control the hub 200 to perform routing if the connection state between the sensor 220b and the hub 200 meets the predetermined condition, Command to the hub (200). For example, the control unit 180 may transmit a control command for controlling the hub 200 to perform routing, based on whether the connection state corresponds to a predetermined condition, even if no separate user control command is received To the hub (200).
Further, the routing may be performed automatically by the control of the hub 200. [ For example, the hub 200 can automatically perform routing when the connection state between the hub 200 and the sensor 220b satisfies predetermined conditions.
Routing refers to the operation of selecting a path for transmitting data (or packet, information) from a calling party to a receiving party in a network (e.g., a wireless sensor network, a routing network, or the like) do. Routing is sometimes referred to as routing.
There are two main ways of routing. One is a method of predetermining a path from a calling side to a receiving side, and the other is a method of selecting a path that is most efficient according to the state of the system or the network at that time.
In the present specification, the latter case will be described as an example. However, the present invention is not limited to this, and the following description may be applied to the former or the latter analogously.
The hub 200 is connected to the sensor 220b in order to establish wireless communication with the sensor 220b for the current installation and when the connection state with the sensor 220b meets predetermined conditions (the sensor 220b and the hub 200 ) Is shorter than a predetermined strength or the time ToF between the sensor 220b and the hub 200 is longer than a predetermined time) can be performed. The routing may be performed by the hub 200 itself or may be performed based on a control command received from the mobile terminal 100, as described above. The mobile terminal 100 may automatically transmit the control command to the hub on the basis of the connection state being set to a predetermined condition, or may transmit the control command to the hub as shown in FIG. 6 (a) Or may be transmitted on the basis of.
For example, the hub 200 may transmit a signal requesting a search for the moving sensor 220b to another sensor 220a installed in advance to enable wireless communication. The other sensor 220a can transmit a signal to confirm whether wireless communication with the sensor 220b is possible, as shown in FIG. 6 (b).
The other sensor 220a may transmit a signal to the hub 200 indicating that wireless communication between the sensor 220a and the sensor 220b is possible when a response signal is received from the sensor 220b.
In this case, the hub 200 may route to perform wireless communication with the sensor 220b via the other sensor 220a.
If the hub 220 determines that another sensor 220a capable of wireless communication with the sensor 220b is determined, the hub 200 inquires (confirms, confirms, confirms, Request) information to the mobile terminal 100. In this case, the information 610b may be displayed on the touch screen 151 of the mobile terminal, as shown in FIG. 6 (b). When a user control command to connect the sensor 220b via the other sensor 220a is applied to the touch screen, the control unit 180 of the mobile terminal 100 transmits the control signal to the hub 200 (Signal) to connect the sensor 220b to the hub 200 via the wireless communication unit 220a. The hub 200 may be connected to the sensor 220b in a wireless communication manner via the other sensor 220a based on the control command.
When the hub 220 is connected to the hub 200 via the other sensor 220a by the routing, the hub 200 transmits information related to the connection state via the other sensor 220a to the router 210 (or a communication module) to the mobile terminal 100.
6 (c), the sensor 220b is connected to the touch screen 151 of the mobile terminal 100 via the other sensor 220a by the routing, (Or information related to the connection status from the hub) is connected to the hub 200 via the second sensor 220a so that the first screen information 600 is connected to the hub 200, And can be displayed. At this time, the touch screen 151 (or at least a part of the first screen information 600) may be displayed with information 610c related to the other sensor 220a via the routing.
5, when the installation is completed in the state that the connection state (that is, the state in which the sensor 220b is connected to the hub 200 via the other sensor) does not satisfy the predetermined condition (or, When the installation completion signal is received from the mobile terminal), the hub 200 can update the routing table.
An example of a routing table is shown in FIG.
The routing table may mean a table including information indicating whether wireless communication between the hub and the sensor and between the plurality of sensors is possible in the system constituting the object Internet according to the present invention. The routing table may be stored in a memory of the hub 200.
As shown in FIG. 7, if the sensors A and B are capable of wireless communication with each other, '1' may be displayed in the routing table. If the sensor B and the sensor C can not communicate with each other, '0' may be displayed in the routing table.
As shown in FIG. 6, when the hub 200 performs routing before installation, the hub 200 may refer to the routing table to route the sensor being installed.
The hub 200 associated with the present invention may update the routing table at least twice. For example, when the hub 200 is connected so as to allow wireless communication with a specific sensor within a predetermined distance, information related to the specific sensor can be updated to the routing table.
As shown in FIG. 6, when the routing is performed before the completion of the installation, the hub 200 connects the routing table to the specific sensor when the specific sensor is connected by way of routing to enable wireless communication via another sensor, can do. If the routing is not performed until the installation of the specific sensor is completed, the secondary update may be omitted.
In addition, the hub 200 may control the specific sensor to search for other sensors capable of wireless communication with the specific sensor when the installation of the specific sensor is completed. When information related to the detected sensor is received from the specific sensor (or from another sensor retrieved from the specific sensor), the hub 200 transmits the routing table to the third You can update it.
The hub 200 updates the routing table for the system constituting the object Internet every time the sensor is installed so that if the wireless communication connection between the hub and the specific sensor becomes unstable, can do. With this configuration, the present invention can provide a control method that can heal a communication error in case of a communication error that may occur.
As described above, according to the present invention, the present invention firstly wirelessly connects sensors and hubs at close distances. Then, the present invention moves the sensor wirelessly connected to the hub and displays the communication state according to the movement of the sensor, that is, the connection state between the sensor and the hub, on the mobile terminal in real time. Therefore, the present invention can provide a user interface that can smoothly communicate with the hub and the sensor while moving to a place where the hub and the sensor are to be connected while moving the hub in a connected state.
In addition, in the related art, when the sensor is first installed at a desired position, the wireless connection between the hub and the sensor is attempted, and if the connection is not smooth, the sensor needs to be moved, resulting in a long installation time and inconvenience. However, the present invention is capable of wirelessly connecting the hub and sensor at a distance that is close to the hub and sensor (in other words, at a distance that the wireless connection is smooth), and moving the sensor wirelessly. Thus, the present invention can minimize the installation time and significantly reduce the communication error rate.
The present invention also relates to a method and apparatus for transmitting screen information indicating that communication is not smooth or screen information capable of performing routing when the communication is not smooth during the movement of the sensor while the hub and the sensor are connected so as to enable wireless connection, And output it to the terminal. Therefore, the present invention guides the user that the communication between the sensor and the hub is not smooth at the corresponding position before completing the installation of the sensor, and the user moves the sensor to a place where communication with the hub is smooth according to the guide The installation time can be minimized, the communication error rate can be reduced, and the reinstallation cost can be reduced.
The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
