In embodiments of the present invention, at least some of the various sensors already known for information collection may be used, and the sensors may be classified as analog sensors and digital sensors, respectively. In this case, the analog sensors may be classified into a plurality of analog sensor groups and modulated, respectively, and the digital sensors may also be classified into a plurality of digital sensor groups and modulated respectively. For example, sensors that measure the bio-impedance through connection with a user are modularized into a group or sensors that measure and utilize acceleration are modularized into a group or sensors that collect external environmental information (for example, Sensors measuring the concentration of carbon dioxide, carbon monoxide, nitrogen dioxide, ozone, fine dust, ultrafine dust, etc., or measuring temperature, humidity, etc.) can be modularized into one group.

Modules 324, 326 and 328 for the analog sensor group can each be individually attached to the connection interface 312 and modules 320 and 322 for the digital sensor group can be attached to the integrated interface Sensor integrated interface 3 330 and digital sensor integrated interface 2 332), and may be attached to the connection interface 312 via such an integrated interface. At this time, the modules 320 and 322 for the digital sensor group may be connected to the connection interface 312 in series. For example, if a new module (not shown) for a group of digital sensors is additionally attached, the new module may be connected in series to the connection interface 312 via module 2 322 and module 1 320.

The sensor controller 310 receives sensing information of a plurality of sensors included in the plurality of modules 320, 322, 324, 326, and 328 through the connection interface 312 and processes the sensed information through the connection interface 312, To the external user terminal (340). Here, the user terminal 340 may be a device of a user who manages information about a user and sensed information such as a smart phone. The network interface 314 may be formed inside or outside the sensor unit 300. For example, the network interface 314 may be a wireless communication module 216 formed in the body 210 of the smart smartphone 200 as shown in FIG.

In yet another embodiment, the sensor controller 310 may further include an output unit (e.g., a display) for processing the received sensing information and outputting the sensed information to the outside. Optionally, the output may replace the network interface 314.

The connection interface 312 may transmit signals associated with modules that are desorbed among the plurality of modules 320, 322, 324, 326, and 328 or signals associated with modules that are newly attached to the connection interface 312 to the sensor controller 310 . At this time, the sensor controller can recognize the module to be detached or newly attached using the transmitted signal.

Hereinafter, examples of the process of collecting sensing information from the modules 320 and 322 for the digital sensor group are shown. Here, it is assumed that the modules 320 and 322 are connected in series to the connection interface 312 in the order of module 1 320, module 2 322, and module 3 (not shown).

Table 1 below shows a table in which the identifiers of the modules 320 and 322 and information on the sensor type are stored in association with each other.

Identifier Sensor type ID 1 Sensors A, B, C ID 2 Sensors D and E ID 3 Sensors F, G, H, I

Here, it is assumed that the identifier of module 1 (320) is ID 1, the identifier of module 2 (322) is ID 2, and the identifier of module 3 (not shown) is ID 3. Information about the sensor type may be automatically identified and stored in the table with the identifier when the modules 320 and 322 are connected to the connection interface 312. [ For example, if a new module 6 is connected in series with the connection interface 312 via module 2 322, the new module 6 sends information about its identifier and sensor type to the sensor controller 310, and the sensor controller 310 may store the received identifier and the sensor type in a table in association with each other. Accordingly, the user can detachably connect various kinds of modules without prior knowledge of the sensor or sensor connection.

4 is a flowchart illustrating an operation method of a sensor unit according to an embodiment of the present invention. The operation method of the sensor unit according to the present embodiment can be performed by the sensor unit 300 described in Fig.

In step 410, the sensor unit 300 may manage the information on the sensors included in the plurality of sensor modules in association with the identifiers of the plurality of sensor modules. The plurality of sensor modules may be modularized to include at least one sensor and may be detachably attached to the connection interface included in the sensor unit. At this time, modularization can be modularized by grouping according to various conditions such as kinds and characteristics of sensors. The information and the identifier of the sensor can be managed by the sensor controller included in the sensor unit 300. [

In step 420, the sensor unit 300 may transmit an information request including an identifier to the plurality of sensor modules according to a schedule. At this time, the plurality of sensor modules can determine whether to respond to the information request by comparing the identifier included in the information request with the identifier of the sensor module itself. This information request can be sent to the plurality of sensor modules by the sensor controller and through the connection interface.

For example, the plurality of sensor modules may include a plurality of digital sensor modules connected in series to the connection interface. Each of the plurality of digital sensor modules compares the identifiers included in the information request with the identifiers included in the information request transmitted by the sensor controller and transmits the sensed information to the sensor controller if the identifiers match each other, To the next digital sensor module. The next digital sensor module may also transmit the sensing information by comparing the identifier included in the information request with its own identifier or may transmit the information request to the next digital sensor module. The digital sensor module may include an integrated interface for the included sensor and may communicate with the connection interface via an integrated interface or with the integrated interface of another digital sensor module attached in series.

In addition, the plurality of sensor modules may further include an analog sensor module. While the digital sensor module is detachably attached to the connection interface in series, the analog sensor module can be detached and attached to the connection interface individually.

In step 430, the sensor unit 300 may collect sensing information transmitted through the plurality of sensor modules and the connection interface in response to the information request. As described above, the sensor module specified through the identifier included in the information request among the plurality of sensor modules can transmit the sensing information in response to the information request, and the sensing information can be transmitted to the sensor controller through the connection interface have

In step 440, the sensor unit 300 may transmit information obtained by processing sensed information or sensing information to the user terminal through the network interface included in the sensor unit. In this case, the schedule described in step 420 may be previously set using information on the sensor type of the plurality of sensor modules attached to the connection interface and information on the user input to the user terminal.

The sensor unit 300 may be included in an object mounted on a specific part of the human body. At least one of the auxiliary objects worn with objects or objects may include a conductive material in the area between the electrodes and the user's skin when the sensor includes electrodes that are in electrical contact with the user's skin.

In step 450, the sensor unit 300 may receive a signal associated with the sensor module, which is detached from the connection interface of the plurality of sensor modules, or a signal associated with the sensor module newly attached to the connection interface, through the connection interface.

In step 460, the sensor unit 300 can recognize the sensor module or the newly attached sensor module that is detached using the received signal.
