2, the IoT management system includes a plurality of IoT devices 20-1, 20-2, ..., 20-n, a network 22, and an IoT device management device 24. [

The IoT devices 20-1, 20-2, ..., 20-n may be digital signage, smart TV, smart watch, smart CE, drone, and the like. The IoT device may be a WoT (Web of Things) device. In particular, digital signage is a communication tool that can induce marketing, advertising, training effects and customer experience of companies. It is a digital tool that provides not only broadcast programs in public places such as airports, hotels, . Such digital signage can also provide a comprehensive software and management platform for controlling commercial digital information displays. Hereinafter, for convenience of explanation, the description of the present invention will focus on digital signage among IoT devices.

The IoT devices 20-1, 20-2, ..., 20-n transmit the device data to the IoT device management device 24. [ Since the device data includes the status and usage information of the corresponding IoT device, the device data reflects the current status of the IoT device. For example, if the IoT device is a digital signage, the status and usage information may include information about the CPU, fan speed, HDD, temperature, application information of the media player, on / off status of the display connected to the media player, , Screen ratio, and the like. An example of the device data will be described later with reference to Fig.

The IoT devices 20-1, 20-2, ..., 20-n according to the embodiment collect the device data for a preset period of time and transmit the collected device data to the IoT device management device 24 at preset intervals send. The IoT devices 20-1, 20-2, ..., 20-n can provide device screens to the IoT device management device 24 upon request of the IoT device management device 24. [ The IoT devices 20-1, 20-2, ..., 20-n may receive control commands for remote control of the IoT device management device 24. [

The network 22 is a wired / wireless network capable of transmitting and receiving data between the IoT devices 20-1, 20-2, ..., 20-n and the IoT device management device 24. [ For example, the network 22 is an Internet network.

The IoT device management device 24 collects device data from the IoT devices 20-1, 20-2, ..., 20-n, compares the collected device data with predetermined standard data, and detects an abnormal signal. And predicts an error of the IoT device in which an abnormal signal is detected. For example, if the temperature value of the device data of a predetermined IoT device is found and the temperature value falls within the threshold value range of the standard data corresponding to the dangerous level, it is predicted as a dangerous level. The IoT device management device 24 provides a pre-service to the IoT device for which an error is predicted, to take measures before an error occurs for each error management step. The error management step may be a normal, warning, critical, or replacement phase. The warning, danger, and replacement phases correspond to the abnormal phase.

3 is a configuration diagram of an IoT device management apparatus according to an embodiment of the present invention.

3, the IoT device management apparatus includes a communication unit 240, a management unit 242, and a control unit 244. [

The communication unit 240 communicates with the IoT devices to collect device data including status and usage information from each IoT device. The communication unit 240 may transmit a control command for remote control to the IoT device. The communication unit 240 can communicate with the IoT device using a predetermined protocol. According to the protocol, the control unit 244 converts the control signal into a control signal conforming to a predetermined protocol and transmits the control signal to the communication unit 240. Communications involving requests and responses to IoT devices are in the form of messages or packets, which may include error information. The protocol can use DMTP (Device Message Transport Protocol). DMTP is a protocol that can represent a large number of states that can not be expressed by existing Message Queue Telemetry Transport (MQTT), and is a new invention protocol of the present invention. For example, since MQTT provides three levels of QoS, expansion is not easy, and parallel processing is difficult due to limited transmission and reception channels. However, DMTP is scalable to QoS, for example, scalable beyond 4-5 steps. In addition, parallel processing is possible through transmission / reception of a multi-channel message, so it is easy to process large-volume data. Furthermore, MQTT is vulnerable to security, but DMTP has a strong security advantage.

If an error is predicted, the communication unit 240 informs the administrator that an error may occur before the error occurs. For example, it sends the results to the administrator for each error management step so that it can cope with the situation immediately. The notification method can utilize all existing communication means such as E-mail, SMS, and ARS.

The management unit 242 manages possible errors of the IoT devices in stages, compares and analyzes device data collected in real time with preset standard data, detects an abnormal signal, and predicts errors of the IoT devices in which an abnormal signal is detected do. The control unit 244 provides an advance service to the IoT devices whose errors are predicted by the management unit 242, before the error occurs in each error management step.

The data management unit 2420 analyzes the device data collected within a predetermined period of time and extracts standard data having a threshold value for each error management step for each IoT device. The threshold value can be set according to the standards set by the manufacturer of each IoT device or according to the criteria set by the administrator. For example, operating time, operating criteria, etc. are defined according to the manufacturer or manager settings. The threshold value may be a set point having an upper limit line and a lower limit line. By collecting device data for a predetermined period and extracting valid standard data from the collected device data, the threshold value can be flexibly set based on the location or environment where the IoT device is installed. Since the amount of equipment data collected during a preset period is vast, large data analysis is performed so that a large amount of collected data can be processed quickly. At this time, the processing speed can be increased by using a map-reduce distributed processing method.

The error predicting unit 2422 compares the standard data extracted through the data management unit 2420 with the device data collected in real time from the IoT device to determine which error management step the collected device data is included in. At this time, if it is included in the predetermined error management step, the IoT device is predicted to be in the error management step. For example, if the temperature of the IoT device is between 50 and 60 degrees, it is defined as the risk management phase through the standard data. If the temperature of the device data collected in real time is 55 degrees, it is predicted that it is in the risk management stage.

The predicted error information can be provided to the manager. The error information may include an error status screen in the IoT device, an error status statement, a contact point for error status processing, and link information thereof. The error information may include error event information related to a network, a display device, a media player, content, and the like.

Here, the error information may include the identifier information of the IoT device in which the error occurred, the time information about the error occurrence, the corresponding error cause information, the position information of the IoT device, and the contact point information according to the error cause information.

The statistical processing unit 2424 generates and manages statistical information from the analysis result of the data management unit 2420 or the prediction result of the error predicting unit 2422. The administrator can easily grasp the error prediction result through statistical information.

The controller 244 according to one embodiment includes a device controller 2440 and a remote controller 2442. The device control unit 2440 receives the standard data for each IoT device from the management unit 242 and controls the IoT device using the received standard data for each IoT device and the device data collected in real time. And transmits the control result to the management unit 242. The remote control unit 2442 requests the IoT device to remotely share the screen through the communication unit 240, receives the device screen, and remotely controls the IoT device by transmitting a control command to the IoT device.
