Description

TECHNICAL FIELD [0001] The present invention relates to a method and apparatus for detecting a device operating abnormally as compared with other devices,

The present invention relates to a method and apparatus for detecting a device that operates abnormally as compared to other devices, and more particularly to a method and apparatus for detecting a device that operates abnormally as compared with the same or similar devices used by other users, And more particularly, to a device and a method for predicting an error of a device by notifying a related person, including a manufacturer, a user, or a combination thereof, of a related content.

In recent years, in order to increase added value in all industries, information technology has been applied to each industry. In this trend, home appliance devices used in the home or office are also connected to information and communication technology, Researches and developments have been actively carried out to allow a user to receive necessary information for a device or to control the operation of the device by making it possible to connect to the device.

Particularly, it is a very important research and development direction to connect the information communication technology and the sensor technology to the device, transmit the measured data from the sensor to the user through the communication network, and analyze the measurement data to control the device. The sensor technology is developed in various types and forms to collect information on specific situations of a specific electronic device, and the information collected by each sensor is transmitted to a necessary place through a network including the Internet. At this time, the device including the sensor digitizes the signal detected by the sensor to transmit the information collected from the sensor to the network, and transmits the signal to the network through the communication interface.

On the other hand, household appliances using electricity in the home can cause various errors if they are used for a long time. At this time, if the module contains errors such as SMPS design, power quality, power management, etc., it will increase the power consumption of the device. Currently, not all electronic products have a way to detect this error. The reason for this is that the high power consumption is not a quantitative function error but a qualitative issue for users.

For example, in the case of a smart phone, if the user uses the battery for a short time, the battery itself or the product itself is judged to be malfunctioning and may be requested to be replaced by a service center. However, Even now, there is no way to recognize this.

However, unlike the past, energy consumption and environmental problems should save more resources, so that the cost of power consumption due to such power leakage will increase more than the cost of replacing the product. You can check to ask the service center to replace the product like a cell phone battery, or to let the user know that it is more economical to replace the product.

Prior art documents incorporating information and communication technologies into home appliance devices include the following. Korean Patent Laid-Open Publication No. 2011-0123652 (November 15, 2011) relates to a power monitoring device, which is provided with a power monitoring device connected to the home appliance in an external form and providing a communication function and a power measuring function to the home appliance There is no need to incorporate a power monitoring device in a home appliance, thereby reducing the manufacturing cost of home appliances.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method and apparatus for detecting a device that operates abnormally as compared with other devices according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a network connection diagram for explaining a method for detecting a device operating abnormally as compared with other devices according to an embodiment of the present invention and a concept of the device.

As shown in FIG. 1, the abnormal device sensing apparatus 100 according to the present invention includes a device 20 connected to the Internet and including a home appliance used in a home or an office, a water supply device, an electric heating device, Or an operation pattern including the power consumption, the maximum power, the power consumption, the power consumption time, the tap water consumption, the tap water usage time, the gas consumption amount or the gas usage time of the device 20 built or attached to the device 20 periodically And is connected to the device status measuring device 21 for measuring non-periodically through a gateway 30 connected to the near field communication NFC, Bluetooth, Zigbee or WiFi.

First, the device 20 is a concept that includes home appliances used in the home or office, a water supply device, an electric heating device, or a gas appliance. In the present invention, a household appliance such as a refrigerator, an iron, Although the device is mainstream, the abnormal device sensing device of the present invention can be used in the automobile or aircraft field. The abnormal device sensing apparatus according to the present invention may be used for monitoring an abnormal operation of a corresponding part by collecting operating states of parts for an automobile or an aircraft and comparing the measured value with a reference value.

On the other hand, the device state meter 21 attached to the device 20 measures the average electric power consumption, the maximum electric power, the electric current, the electric power consumption time, the electric power consumption Consumption pattern, and the like, and transmits this information to the abnormal device sensing apparatus 100 connected to the Internet by using NFC, Bluetooth, ZigBee, and Wi-Fi, which are short-range wireless communications.

In the case of household appliances, it is attached to the power module of household appliances, or the measured values of the current, voltage, etc. constituted by separate adapters are converted into digital data, and then transmitted to the abnormal device sensing device through communication means. Of course, water consumption, water pressure, tap water usage time, gas consumption amount or gas usage time are measured and output to the abnormal device sensing device via the network in case of water supply equipment, electric heating equipment or gas equipment respectively.

The device status meter 21 is attached to the device 20, which is a home appliance used in the home or office, to determine an average power consumption, a maximum power, a power consumption pattern, etc. of the device 20, And transmits it to the abnormal device detection apparatus using Wi-Fi, which is communication NFC, Bluetooth, ZigBee or remote wireless communication.

That is, since the abnormal device sensing apparatus 100 is connected to the user terminal 10 or the device 20 through NFC, Bluetooth, Zigbee, Wi-Fi or Ethernet, the communication method will be briefly described below.

NFC is a non-contact type short-range wireless communication module that uses 13.56MHz frequency band as one of RFID tags and transmits data between user terminals at a distance of 10cm. These NFCs are widely used not only for payment but also for travel information transmission, transportation and access control locks for goods information and visitors in supermarkets and everyday shops.

As a feature of NFC, it is possible to operate the terminal with tag embedded in the active mode as an extension concept of existing RFID, so that not only the function as a tag, but also the reader that reads the tag. Tag performs a function of a writer for inputting information, and peer-to-peer communication between the terminal and the terminal is possible. Therefore, in order to connect between the device state meter 21 and the user terminal 10 or the gateway 30 through the NFC, communication can be performed only within a distance of 10 cm.

Another short-range wireless communication function, Bluetooth, is one of the short-range wireless communication standards. It refers to a technical standard for wirelessly connecting and controlling various electronic and information communication devices within a radius of 10 m using 2.45 GHz frequency. Data can be exchanged at high speed by using radio frequency without physical cable for communication between various digital appliances as well as information communication devices such as computers, printers, mobile phones and PDAs in home or office. Therefore, in order to connect between the device status gauge 21 and the user terminal 10 or the gateway 30 using Bluetooth, which is one of the functions for the short-range wireless communication,

ZigBee is a wireless personal area network standard operating at 868 MHz, 902-928 MHz, and 2.4 GHz, and a wireless personal area network is a personal area network in which peripheral access is wirelessly performed. With this ZigBee, data can be exchanged at a maximum speed of 250 Kbps between peripheral devices within a distance of 50 m or less within a wireless personal area network, and is based on the 802.15 standard approved by IEEE-SA Feature. ZigBee also provides high data throughput efficiency in low impact environments. ZigBee is therefore ideally suited to home, business and industrial automation applications where control devices and sensors are used. These peripherals operate at low power, which means that the battery will last longer with a very low duty cycle, typically less than 0.1%. Examples of applications that work well with ZigBee include HVAC, lighting systems, intrusion detection, fire detection, and detection and notification of abnormal events.

In order to connect between the device state meter 21 and the user terminal 10 or the gateway 30 using ZigBee, which is one of the functions for short-range wireless communication, the distance should be within 50m.

Meanwhile, as shown in FIG. 1, it can be seen that the device status measuring device 21 is connected to the gateway 30 using the short-range wireless communication (see (1) in FIG. 1). As shown in the figure, it is possible to communicate between the device state meter 21 and the gateway 30 by using wired / wireless communication such as NFC, Bluetooth, RFID, Zigbee, WiFi, PLC, SUN and 6LoWPAN.

The gateway 30 connected to the device status meter 21 is connected to the Internet 40 through Ethernet or WiFi (see (2) in FIG. 1). Thus, the device 20 including various home appliances according to the present invention, Is connected to the abnormal device sensing apparatus 100 connected to the Internet via the device state meter 21 incorporated or attached thereto (see (3) in FIG. 1). In this situation, the abnormal device detection device stores the device-specific set values and actual measurement values collected in the device in the database 105 connected via Ethernet or Wi-Fi. Accordingly, the abnormal device detection apparatus 100 periodically stores the set value and the measured value for each device in the database, and examines and analyzes whether the measured value exceeds the set value based on the stored set value and the measured value, When it is expected to occur or to occur, it notifies the related persons including the user, the manufacturer, or a combination thereof, of the operation status of the device (see (4) in FIG. 1).

That is, information such as average power consumption, maximum power, and power consumption pattern of each of the devices 20 via the device status measuring device 21 attached to the device 20 is transmitted to the NFC, Bluetooth, Zigbee, etc. And communicates with the gateway 30 using short-range wireless communication. At this time, the gateway 30 can communicate with the user terminal 10 using the Wi-Fi, and accesses the Internet 40 via Wi-Fi and Ethernet. The Internet periodically senses the state of the device 20 by transmitting and receiving information to and from the abnormal device detection device 100 via a wireless Internet or Ethernet using Wi-Fi, and the device 20 may cause an error A message is transmitted through the user terminal 10 to notify the user of the status of the device 20. [

Bluetooth, RFID, Zigbee, WiFi, PLC, SUN, 6LoWPAN, etc. between the device, the gateway, the device and the user terminal, the user terminal and the gateway, the gateway and the Internet, Communication can be performed using the communication.

The user terminal 10 may also be a wired or wireless terminal including a smart phone, a tablet PC, a netbook, a notebook, a PC, or a combination thereof.

Here, 6LoWPAN is a method for applying Internet protocols to small-sized devices and low-power devices with limited processing capability capable of participating in the Internet of Things (IoT), and is an encapsulation method in which IPV6 packets can be transmitted and received through IEEE 802.14.4 Encapsulation and header compression. Thus for use in IP networking for low power wireless communications.

In addition, SUN is standardized by IEEE for communication between final electric consumers and utilities. It covers communication distance from several meters to several tens of kilometers and transmits data at 40kbps ~ 1Mbps data transmission rate in outdoor for low power consumption. . Accordingly, in the present invention, an energy saving system, a wireless remote meter reading system, an in-home display (IHD) system, and a home network system are provided through a configuration in which data is transferred between a home gateway and a wired / wireless Internet, , Remote ground fault detection system, smart grid application of electric vehicle, apartment location based service, disaster prevention monitoring system.

Until now, the abnormal device sensing apparatus 100 has collected the information by measuring the state of each device through the device state meter 21 and analyzed the information to determine whether there is an error in the operation pattern of the corresponding device, The analysis of the process is conceptually explained.

Hereinafter, an abnormal device sensing apparatus according to the present invention will be described in detail.

2 is a block diagram showing the configuration of an apparatus (abnormal device sensing apparatus 100) for detecting a device operating abnormally as compared with other devices according to an embodiment of the present invention.

The abnormal device sensing apparatus 100 includes a communication interface 110, an information collecting unit 120, an abnormal device sensing unit 130, a user interface 140, a controller 150, or a combination thereof.

The communication interface 110 is an interface means for transmitting and receiving communication data between the device status measuring device 21 and the abnormal device sensing apparatus 100. The communication interface 110 transmits data received by the device status measuring device 21 to the information collecting unit 102 ). The information received by the information collecting unit 120 is stored in the database 200 under the control of the control unit 150 and further transmitted to the abnormal device sensing unit 130 through the control unit 150 to detect whether the device is an abnormal device And is notified to the user through the user interface via the control unit 150. [

On the other hand, the information collecting unit 120 receives measurement data on the status of the device from the device status measuring unit 21 through the communication interface 110. The received data is classified into devices and stored in the database 200. The information collected by the information collection unit 120 is transmitted to the abnormal device detection unit 130 through the control unit or to the user via the user interface 140 via the control unit 150. [ The state information of the device 20 which is a normal home appliance used in home, measured by the device state meter 21, is received from the communication interface 110 and the average power consumption of the household appliance 20, And a power consumption pattern and stores the collected information in the database 200 and transmits the information to the abnormal device sensing unit 130 via the control unit 150. [

The abnormal device detection unit 130 detects the abnormal device by analyzing the data received from the information collection unit 120 through the control unit 150, the setting value for each device, the measurement value for each device, or a combination thereof. At this time, the measurement value may be received from the information collection unit 120, or may be extracted from the database. The detected information transmits the status information of the device 20 to the user terminal 10 through the control unit 150 and the user interface 140. Of course, the information detected by the abnormal device detection unit 130 may be displayed on the user terminal directly through the user interface without passing through the control unit.

The user interface 140 interacts with the control unit 150 to output information on the abnormal device to the user terminal 10, outputs information on the status of the device to the user terminal, And provides a user interface capable of performing various controls necessary for operating the sensing device in a user-friendly manner.

In addition, the controller 150 controls the overall operation of the abnormal device sensing apparatus 100, and coordinates the respective interfaces between the user interface and the communication interface to smoothly operate. Also, between the information collecting unit and the abnormal device sensing unit, The user inputs a desired condition or performs control so that the user can output necessary information. In addition, it controls the operation of the information collecting unit to store the device-specific set values and the measured values, or supplies the necessary data to the abnormal device detecting unit 130.

That is, for example, after analyzing and storing the average power consumption, the average maximum power, the average power consumption pattern, and the like of the home appliance device 20, the stored measured value is compared with the reference set value as a reference, It transmits data to the user interface 140 and transmits the power usage state of the home appliance device 20 to the user terminal 10. [

The database 200 for storing device-specific set values / measurement values stores a set value set through the user terminal 10 or each device 20 or an average power consumption, a maximum power, a power consumption pattern, etc. of the devices And receives an input from the outside or internally calculates and stores it, and compares the average of the stored values periodically with the actual capacity to determine whether the device 20 is faulty. Also, it is possible to set a range of an error, perform a registration / cancellation process of the user terminal 10 through the user interface 140, and set a method of notifying a message transmission method, a number of times, and the like.

The abnormal device sensing apparatus having such a structure may be implemented in a user terminal such as a smart phone to operate as an app, but in this case, it is difficult to acquire information about other devices. However, in order to overcome such disadvantages, it is possible to implement such that information of other devices is not required to be stored locally in a large amount by accessing the device-specific setting values or measurement values stored in the database on the Internet.

3 is a diagram illustrating a process of comparing a reference value and a measured value of a device status according to an exemplary embodiment of the present invention.

As shown in FIG. 3, when a table for the reference value and the measured value is maintained in the database and the measured value in real time is compared with the reference value stored in the database and it is expected that the measured value exceeds or exceeds a predetermined ratio, And if it exceeds a certain criterion, the information of the corresponding device is transmitted to the user by a method of shutting off the power.

That is, the abnormal operation of each individual device 20 is detected by periodically comparing the reference value preset for the state of the device 20 with the measured value measuring the state of the device 20 in real time. At this time, the reference value may be set by automatically loading basic information provided by the manufacturer that manufactures the device 20, or may be a set value arbitrarily set by the user, an average of power values consumed by the device 20, The average operating condition measured in the case of the same or similar device used by the user can be used as a reference value. Also, the measurement value refers to data received from the abnormal device sensing apparatus 100 in real time that the device status measuring unit 21 has measured and delivered the current status of the devices 20 through the Internet.

That is, in the case of an air conditioner, a set value such as a target temperature or humidity of the air conditioner is combined with environmental information such as an ambient temperature, and the operation state of the device according to the surrounding environment is detected as a normal operation or an abnormal operation, do. The set value may be directly set by a user, a value set by a manufacturer may be set as a reference value, or an average value of the same or similar products used by other users may be set as a reference value. For example, in the case of a home appliance, it is possible to accurately detect whether there is a problem in the power consumption of the device 20, even if the power consumption such as the power consumption, the maximum power, and the power consumption pattern is periodically checked.

As shown in the figure, if the difference between the reference value and the measurement value is within the error range for each device, the device is recognized as a normal device. On the other hand, if a measurement value deviating from a predetermined error range is detected, Or recognizes that an error has occurred in the device, or recognizes that the device is out of order.

For example, if the actual measured value based on the value provided by the manufacturer for rated current, rated voltage, power consumption, etc. in the actual situation should flow about 1.5 A, but if 2A flows, the average power consumption per unit time is excessively set And this phenomenon is out of the error range, and an alarm informing the user terminal of the device error is transmitted.

4 is a diagram illustrating a process of setting an operation environment of a device according to an embodiment of the present invention and notifying a user terminal of an error content when an error is detected. As shown in the figure, the user sets an environment of the device 20 used by the user and notifies the user terminal 10 of the contents of the error when the error is detected. That is, the air conditioner, which is a home appliance commonly used in the home, will be described as an example.

When the user sets an operation such as a desired temperature and a desired humidity on an air conditioner used in home appliances, the abnormal device sensing device 100 passes through the gateway 30 and the Internet 40 as described above with reference to FIG. 1, And informs the user terminal 10 that the environment information of the air conditioner is input to the user terminal 10 through the Wi-Fi as shown in FIG. 4, primarily. Then, when the air conditioner is operated, the power consumption, the maximum power, the power consumption pattern, and the like are consumed more than the average amount stored in the abnormal device sensing apparatus 100, It is possible to notify the user that there is a problem with the current consumption of the air conditioner.

FIG. 5 is a flowchart illustrating a process procedure of a method for detecting a device operating abnormally as compared with other devices according to an embodiment of the present invention.

As shown in FIG. 5, first, the user sets the environment information and the operation range according to the device as the reference value, sets the reference value using the rated value provided by the manufacturer, A reference value is set by setting an average value as a reference value or by combining them, and storing them in a database to prepare a reference value of an operation range for each device (S110). This process can be performed, for example, in such a way that the abnormal device sensing apparatus 100 obtains an average value directly from the manufacturer of each device 20 without user intervention, It is possible to automatically calculate and set the average value for each step (e.g., start, normal operation, standby state, etc.). It is also possible for the user to separately adjust and set a reference value for judging an error according to the operation range or condition of each device. The set values for each device are stored and managed in the database, and the operation range for determining an error according to the aging of the device can be modified and updated. However, when the power consumption is out of the allowable range, the degree of inefficiency can be calculated and notified to the user in comparison with the optimum operating condition of the device.

Next, the operation state of each device is measured in real time through the device state measuring device 21 provided for each device, and the measured value is collected in the abnormal device sensing apparatus 100 (S120). It is also possible to measure the occurrence of an error in real time by collecting measured values according to a predetermined period or in accordance with an event in real time. However, the measurement value is collected during a certain period, and the difference between the reference value and the measured value is accumulated Therefore, it is preferable to continuously store measured values measured in real time in the database, since the severity of the situation may be judged. If an error is reported to the user and the user takes the appropriate action, it should be recognized as an event and stored and managed separately.

Subsequently, the reference value and the measured value for each device are compared with each other to detect whether the difference is within an error range or not, and the degree of the error is determined according to the difference (S140). That is, in the process of periodically or collecting the measured values of the operation of each device 20 by the abnormal device detection apparatus 100, the device 20 continuously compares the measured values with the reference values, . The degree of error severity is notified according to how far the result of the comparison exceeds the allowable range according to the degree. In addition, the error information reported in this manner manages how the user responds in the future. If the user does not take action continuously, the error becomes more serious. In this case, the abnormal device detection device forcibly measures the device status And instructs the device to stop operating. The history information for this case is of course stored and managed in the database. When the device is managed for a predetermined period, the expected failure in the future of the device can be known in advance according to the mode of the measurement value measured from the device. That is, the abnormal device sensing apparatus according to the present invention predicts a failure of a specific device and performs a preliminary action, thereby preventing a more serious condition due to a failure.

 If an abnormal device is detected, a message (severity, emergency, cutoff, warning, concern, etc.) corresponding to various states is generated and output to the user terminal according to the determination result. For such detected or predicted errors, the abnormal device detection device informs the user of the status of the device through the user terminal using the wired / wireless communication method such as NFC, Bluetooth, ZigBee, WiFi, and Ethernet. For example, if a user sends environment information such as a set value of the electronic product itself and weather and humidity at a specific time, it can be detected that there is a problem in the power consumption of the device even if only the power consumption is measured, . This is because even if the device status measuring device provided in each device is constituted by an extremely simple passive circuit and an A / D converter with only communication means, it is possible to sufficiently grasp the state of the device, which is another feature of the present invention.

In addition, the user can access or monitor the desired information whenever the user is able to access the device regardless of where he / she is using the network. In addition, it is possible to analyze various conditions including the defective device, the aging of the device for a long period of time, the poor environment to use, poor user habits, or a combination thereof. It is also possible to produce the information for use by the manufacturer or related organizations.

Above all, according to the present invention, there is an advantage that a user can be relied on the safety of a device used by himself or herself, and can immediately grasp how energy efficient his or her product is compared to other products.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
