FIG. 1 is a block diagram illustrating an exercise device according to the present invention, and FIG. 2 is a plan view illustrating an exercise device according to the present invention. Referring to FIG. 1, the apparatus for practicing the embedded processor of the Android operating system of the present invention has a structure in which the Android tablet board 110 and the peripheral board 120 are mounted on the main board 100, and the Android tablet board 110 The USB expansion control board 200 is connected.

The Android tablet board 110 has an embedded processor 112 and the embedded processor 112 has an Android OS. As shown in FIG. 2, on the Android tablet board 110, a display means 114 is installed. Preferably, the display means 114 is an LCD (Liquid Crystal Display) or an AMOLED (Active Matrix Organic Light Emitting Diode) supporting a GUI (Graphic User Interface). For example, the display means 114 is a 10.1-inch LCD equipped with a touch panel, and supports TUI (Touch User Interface) like a commercial Android device.

The embedded processor 112 is a processor similar to a processor mounted on a commercial Android device such as a smart phone or a tablet PC, for example, Samsung's Exynos 4412 Cortex-A9 Quad. It is possible to construct the same app environment as that of the actual tablet PC by using the embedded processor 112 and to read the detection signal from the sensor unit 140 of the peripheral board 120 or to control the driving of the actuator unit 150 Can be controlled. These operations can be confirmed by the user through the display means 114. [

The peripheral device board 120 includes a programmable logic controller 130, a sensor unit 140, an actuator unit 150, and a power supply unit 160 for supplying power to each component. The programmable logic controller 130 may route the program separately from the embedded processor 112 of the Android tablet board 110 and may read the detection signal of the sensor unit 140 or output the detection signal of the actuator unit 150 .

The sensor unit 140 includes a gyro sensor 141, an acceleration sensor 142, a geomagnetic sensor 143, a GPS module 144, a switch 145, and a keypad 146, as shown in FIG. do. These sensors are basically installed in an ordinary Android device and are provided in a general embedded processor practicing apparatus.

In the Android tablet board 110, through the display means 114,

The actuator unit 150 includes an LCD 151 for text display, an organic light emitting diode (OLED) 152, a light emitting diode (LED) 7 segment 154, a dot matrix 155, .

The sensor unit 140 transmits a sensing signal to the programmable logic controller 130. The programmable logic controller 130 periodically stores the sensing signal read by the sensor unit 140. And displays the sensing signal through the LCD 151 or the OLED 152. For example, the posture, orientation, motion recognition result, and the like of the training apparatus may be displayed.

In parallel with this, the sensor unit 140 transmits a sensing signal to the embedded processor 112 of the Android tablet board 110, and the sensing result is displayed through the display unit 114. Accordingly, the user can practice the results of the exercises performed by the programmable logic controller 130 with respect to the Android device, and learn various hardware controls and driver creation in the Android environment.

Herein, the embedded system of the present invention can be practiced in various application environments by providing the USB expansion control board 200, and it is also possible that the USB expansion control board 200 is provided with the Android tablet board 110 ) Is recognized as a USB device, so that the contents practiced can be directly applied to a commercial Android device so as to be confirmed.

The USB expansion control board 200 is connected to the USB connector of the connection port 170 and comprises a USB host controller 210, a microprocessor 220 and an extension module connection unit 130 as shown in FIG.

Since the USB host controller 210 recognizes the connected device as a USB slave device, the USB host controller 210 recognizes the Android tablet board 110 as a USB device. And the embedded processor 112 mounted on the Android tablet board 110 supports the Android Open Accessory (AOA) protocol as in a commercial Android device. Accordingly, the USB expansion control board 200 can easily communicate with the application programs of the embedded processor 112 according to the AOA protocol.

FIG. 3 shows an example of an extension module 240 connected to the extension module connection unit 230. 3, an accessory development kit (ADK) relay module 241, an ADK temperature sensor module 242, an ADK joystick module 243, an ADK composite motor module 244, ADK power A development kit such as various sensors or actuators such as a driver module 245, an ADK color LED module 246, etc. may be connected. These development kits are development kits for accessories for Android devices.

For example, when the ADK temperature sensor module 242 is connected to the expansion module connection unit 230, the microprocessor 220 periodically reads the detection signal of the ADK temperature sensor module 242. The microprocessor 220 transmits the sensed value read by the USB host controller 210 to the Android tablet board 110, which is a USB device recognized by the USB host controller 210. The Android tablet board 110 executes an application program for displaying the temperature value and displays the temperature value detected by the ADK temperature sensor module 242 through the display means 114. [

The important point is that if the USB expansion control board 200 is detached from the main board 100 and connected to a commercial Android device after the practice is completed, the same practice can be performed in an app environment on a commercial Android device.

4 shows an example of a user application using the USB expansion control board 200. In FIG. For example, after the ADK compound motor module 244 is connected to the extension module connection unit 230 to practice motor driving, the driving result can be applied to the commercial Android device 300. In this case, the user can exercise the remote control of the wireless mobile robot 400 in the Wi-Fi environment by using the commercial Android device 300 such as a tablet PC.

As described above, the embedded practice apparatus of the Android operating system of the present invention is advantageous in that a creative capstone design can be designed using various ADKs and application modules.

In other words, all of the above embodiments should be interpreted by way of example and not by way of limitation. Therefore, the scope of protection of the present invention should be determined in accordance with the appended claims rather than the above-described embodiments, and should be construed as falling within the scope of the present invention when the constituent elements defined in the appended claims are replaced by equivalents.
