Since it is unknown, the control device 200 queries the controllable function, and the control device provides a list (list) of its controllable items in response to the query. Upon receiving the list of controllable items, the remote controller 100 selects one of the controllable items, sets a control value, and then transmits a control request signal to the control target device 200, and receives the control target. The device 200 changes the requested control value to the requested item and performs a function corresponding to the control item. For example, in the case of a function item to measure, a measurement function is performed according to a control value (measuring period, period, etc.).

Knowing the controllable items of the device to be controlled in advance, the communication procedure is simplified and the amount of communication data is reduced because the remote control of a device from a computer or device does not require a procedure for querying and responding to functions that can be controlled by the device to be controlled. In turn, power consumption will be reduced.

According to Gartner, the number of things using IoT technology by 2009 was 900 million, but by 2020, this number is expected to reach 26 billion. With so many things connected, querying and responding to a controllable item to control the controlled device would be a tremendous load on both the remote control device and the controlled device.

Therefore, the necessity of a technology that does not perform a procedure for querying and responding to a function capable of controlling a device to be controlled has emerged with the emergence of the IoT.

The image recognition unit 150 performs a function of recognizing a product code from a camera function and a captured image. The control unit 120 controls and manages components in the remote control device, reads a registered product code to check a controllable item, selects one of the controllable items, and controls a value of the corresponding item. And transmits a control request signal including a control value to the control target device.

The remote control apparatus 100 first recognizes and registers a product code of a device to be controlled. There are many ways to recognize and register the product code, I) How to receive the product code information through the product code server 300 to communicate with the remote control device to register with the remote control device, II) of the remote control device The user checks the product code attached to the device to be controlled, and registers the product code in advance in the memory unit 140 of the remote control device, III) the camera of the image recognition unit 150 to the control device 200 There is a method of photographing the attached product code, recognizing the product code (serial number) from the photographed image, and registering the product code with the remote controller.

The product code (eg serial number) will contain items that can be controlled for each product. As an example of the product code, one of the devices to be controlled, the ultrasonic device is registered three remotely controllable items and put kiot-iot-001 in the code. The first product code (serial number, S / N) is made up of the product code kiot-iot-001-20151201-001, which is a combination of kiot-iot-001 and other information 20151201-001 that identifies the control item. For example, if the product code is kiot-iot-001-20151201-001, a code identifying the controllable item kiot-iot-001 is included together. In the case of the identification code kiot-iot-001, it means three controllable items related to the measurement in the ultrasonic device, and whether to drive the measurement function with the control value, toggle (ON) or OFF (ON) Set to a specific value (eg, 10 msec or 100 msec units) at intervals of measurement time, and set whether or not a measurement interval limit value (eg, cm units). The controlling device performs the measurement function according to the set control value.

On the other hand, if the product code does not include a remotely controllable item identification code, and in the case of a normal product code, as shown in FIG. Querying and receiving the controllable item list in response thereto. This is a procedure necessary for mutual compatibility with the controlled device in which the product code according to the present invention is not assigned to the controlled device.

When the product code of the device to be controlled is registered, the remote controller 100 checks a list of controllable items using the controllable item identification code included in the product code information using the product code information. The kiot-iot-001, which is a code for identifying the remote controllable item, is included in the product code, so that the remote control apparatus knows which controllable item the control target device includes. As shown in FIG. 6, kiot-iot-001 and kiot-iot-002 are shown as codes for identifying the remotely controllable item, but additionally, increasing the remotely controllable item is obvious to those skilled in the art. It is.

As described above, the controllable item for each product may be received from the product code server or stored in its own memory. However, in the IoT environment, it is expected that there will be hundreds to hundreds of billions of control target devices, which may require a huge amount of storage space. However, in the present invention, since only a plurality of remotely controllable items need to be included in the remote control apparatus, a plurality of control target devices can be controlled with a small memory capacity.

The remote control apparatus 100 reads the product code through the method of recognizing the product code without receiving information on the controllable item from the control target device, and checks the controllable item identification code included in the product code. In addition, the list of remotely controllable items matching the identification code is read from its own memory and displayed on the display screen included in the user interface 130. The remote control apparatus may store a remote control application that displays a list of remotely controllable items on a display screen in its own memory, and then display the list of remotely controllable items on the display screen by running the application. In addition, when displaying a list of specific remote controllable items, a list of items that can be downloaded and installed from a server (not shown) storing a remote control application for each control target device and installed may be displayed on a display screen.

The remote controller 100 selects one or more of the displayed controllable items, sets a control value, and then transmits a control request signal to the control target device 200. Infrared communication may be used to transmit a control request signal between the remote control device and the controlled device, but in addition, zigbee. Bluetooth, WiFi, LTE, etc. may be used as the communication method.

The controlling device 200 receives the control request signal from the remote control apparatus 100, checks the requested item using the received control request signal, and then changes the controllable item to the requested control value, thereby controlling the controlling device. The function of the item is operated according to the control value received at 200.

3, when there are a plurality of devices including the same controllable item (kiot_iot_001) in the product code among the plurality of control target devices 200_1, 200_2, 200_n, as shown in FIG. 6, multicasting or broadcasting The control request signals may be collectively received using a casting protocol to change the control values of the controllable items of the plurality of control target devices according to the control request signals sent by the remote control apparatus 100 at one time.

As shown in FIG. 7, the remote controller may register a product code of a device to be controlled in advance. When the remote control apparatus executes the remote control application, as shown in FIG. 7, the registered control target device list and the controllable item are displayed.

If a remote control application of a remote control device is executed by a user and a menu called Control is selected on the display screen, a device list and a screen for changing device settings are displayed. The initial screen displays the setting screen of kiot-iot-001-20151201-001, which is the first of the registered product codes. Selecting one of the devices registered by the user changes the setting change screen accordingly.
