The failure occurrence detection notification system 11 transmits failure information to at least one warning group of the plurality of warning groups using the communication network 12 when a failure occurs in the automation device 10. 1 includes a warning group A user terminal 13-1, a warning group B user terminal 13-2, and a warning group N user terminal 13-3. Obviously, the number of warning groups may vary depending on user settings. Hereinafter, the failure occurrence detection notification system 11 will be described in detail with reference to FIG. 2.

2 is a block diagram showing the configuration of a failure occurrence detection notification system 11 according to an embodiment of the present invention.

The failure occurrence detection notification system 11 includes a control unit 20, a detection unit 21, a communication unit 22, an output unit 23, a storage unit 24, an input unit 25, and a power supply unit 26. The output unit 23 includes a display unit 23-1 and an audio output unit 23-2, and the input unit 25 includes a key input unit 25-1 and an audio input unit 23-2.

The power supply unit 26 receives a predetermined power from the outside and supplies power to the device constituting the failure occurrence detection / notification system 11 according to the present invention. In general, the power supply unit 26 receives a voltage of AC220V from the outside, and converts the voltage into a voltage of DC 5V through a transformer and a rectifier circuit built therein and supplies it to the failure detection notification system 11.

The input unit 25 includes a keyboard provided with a plurality of character buttons, numeric buttons, special character buttons, shortcut keys, and the like, and a key input unit 25 including a menu key and an enter key configured to perform various menu settings for key input through the keyboard. Contains -1. The input unit 25 also includes a voice input unit 25-2 for selectively inputting an administrator's voice message according to the operation of the key input unit 25-1.

Therefore, the administrator can store various voice messages in the storage unit 24 through the voice input unit 25-2 while manipulating the keyboard, menu key, and enter key of the key input unit 25-1, and various key buttons of the key input unit 25-1. Information about a plurality of warning groups can be stored using.

In addition, the manager may store failure information that may occur in the automation device 10 by operating the input unit 25 in the storage unit 24.

The storage unit 24 stores the measures for the fault information and the fault information that may occur in the automated device 10. In addition, the storage unit 24 stores information on a manner of notifying the failure information generated in the automated device 10. That is, the storage unit 24 stores the output voice message and various announcements according to the type of the failure, and stores information on the warning group to be notified according to the level of the failure. This will be described later.

The sensing unit 21 is connected to a predetermined point of the automation device 10, and detects a failure state of the automation device 10 by comparing the data value of the connected point with a preset reference value. The detection unit 21 detects the automation device 10 in real time, so that a failure can be detected quickly.

The output unit 23 includes a display unit 23-1 for displaying information input to the input unit 25 and information required for display according to a command of the controller 20, and a voice output unit 23-2 for outputting the corresponding information as a voice.

That is, the output unit 23 indicates the operation state when the failure occurrence detection / notification system 11 for the automation device 10 according to the present invention is operated, and inputs information on various phone numbers or failure information through the key input unit 25-1. And a display unit 23-1 for displaying. In addition, the output unit 23 includes a voice output unit 23-2 which outputs a predetermined voice signal such as an alarm or notifies the adjacent manager to the failure state when the failure state of the automation device 10 is detected from the detection unit 21.

The communication unit 22 is configured as a wired or wireless network, and when a detection signal corresponding to a failure state of the automation device 10 is input from the detection unit 21, the communication device 10 is controlled by at least one user terminal group among the plurality of user terminal groups under the control of the control unit 20. Send fault information. Of course, it is obvious that the failure information transmitted to the user terminal group may use a voice message or a text message.

The controller 20 controls the detector 21, the communication unit 22, the output unit 234, the storage unit 24, the input unit 25, and the power supply unit 26. That is, when the controller 20 receives the failure state of the automation device 10 from the detection unit 21, the controller 20 diagnoses the received failure state. If the diagnosis determines that the failure cannot be self-repaired, the difficulty level for the failure condition is determined. The controller 20 transmits the failure information to at least one user terminal group of the plurality of user terminal groups according to the determined difficulty. Hereinafter, detailed operations of the controller 20 will be described with reference to FIGS. 3 to 5.

3 is a diagram illustrating an operation performed by a control unit according to an embodiment of the present invention. Hereinafter, an operation performed by the control unit according to an embodiment of the present invention will be described in detail with reference to FIG. 3.

In step 30, the controller instructs the control unit to detect the automation device in real time. The detector monitors the automation device in real time according to a command of the controller. Of course, you can adjust the monitoring cycle of the automation device according to the user's setting. That is, the sensing unit may monitor the automated device at regular intervals according to a command of the controller. However, as the monitoring cycle of the automation device becomes longer, when a failure occurs in the automation device, the control unit may not diagnose the failure in real time. Therefore, it is preferable that the controller instructs the control unit to sense the control command to monitor the automation device in real time.

In step 31, the controller analyzes the detection-related data received from the detector to determine whether a failure has occurred. If it is determined that a failure has occurred in the automation device, the controller moves to step 32, and if the failure does not occur, moves to step 30 to instruct the detection unit to detect the automation device in real time.

In step 32, the controller generates failure information using the detection-related data. The generated fault information includes the time of the fault, the location of the fault, the cause of the fault, and whether the same fault has occurred before. The controller stores the generated fault information in the storage unit. Table 1 below shows an example of the failure information generated by the control unit.

TABLE 1

In step 33, the controller measures the level of the failure information. That is, the controller analyzes the generated failure information and measures the level of the corresponding failure.

The method for measuring the failure level is stored in the storage unit in advance by the user. For example, the user may be able to measure the failure level according to the location of the failure. That is, the failure level can be set low when the failure location is a belt, and the failure level can be set high when the failure location is a power source. In addition, when the location of the failure is unknown or the cause of the failure is unknown, the failure level can be set high.

In step 34, the controller selects a warning group corresponding to the measured failure level. That is, different warning groups are selected depending on when the failure level is high and when the failure level is low. Table 2 below shows an example of selecting a warning group corresponding to the failure level.

TABLE 2

According to Table 2, the control unit selects the warning group A when the failure level is level 1, and selects the warning group B when the failure level is level 2. In addition, the controller selects the warning group C when the failure level is level 3, and selects the warning group A and the warning group C when the failure level is level 4.

In step 35, the controller notifies the warning information to the terminal of the user included in the selected warning group. The warning information transmitted to the user terminal may include a date and time of failure and a cause of the failure. In general, the warning information may be briefer than the failure information stored in the storage in consideration of the transmission capacity.

Although FIG. 2 illustrates an example of notifying warning information to a warning group selected according to a failure level, it is obvious that the warning information may be notified to a warning group selected according to a failure cause according to a user's setting. That is, the controller may transmit the failure information to the user terminals included in the warning group A when the cause of the failure is a belt, and transmit the failure information to the user terminals included in the warning group B when the cause of the failure is the power. In addition, it is obvious that the failure information transmitted to the user terminal may also vary depending on the cause of the failure.

In addition, the controller may output the failure information using the output unit. That is, the controller may control the voice output unit to output failure information by using a different voice output method according to the failure level. Different voice output methods may include volume, different beep sounds, and the like.

4 is another diagram illustrating an operation performed by a control unit according to an embodiment of the present invention. Hereinafter, an operation performed by the control unit according to an embodiment of the present invention will be described in detail with reference to FIG. 4.

In step 40, the controller instructs the control unit to detect the automation device in real time. The detector monitors the automation device in real time according to a command of the controller. Of course, you can adjust the monitoring cycle of the automation device according to the user's setting.

In step 41, the controller analyzes the detection-related data received from the detector to determine whether a failure has occurred. If it is determined that a failure has occurred in the automation device, the controller moves to step 42, and if the failure does not occur, moves to step 40 to instruct the detection unit to detect the automation device in real time.

In step 42, the controller generates fault information using the detection related data. The generated fault information includes the time of the fault, the location of the fault, the cause of the fault, and whether the same fault has occurred before. The controller stores the generated fault information in the storage unit. Table 3 below shows an example of failure information generated by the controller.

TABLE 3

In step 43, the controller determines whether information corresponding to the generated failure information is stored. According to Table 3, the first failure information does not have corresponding information because the same failure has not occurred before, and the second failure information has stored the corresponding information because the same failure has occurred twice before. The control unit moves to step 48 if the same failure information is stored, and moves to step 44 if the same failure information is not stored.

In step 44, the controller determines whether failure information related to the generated failure information is stored. The controller moves to step 48 if the related failure information is stored, and moves to step 45 if the related stored information is not stored. This is because there is no same fault information as the generated fault information, but it is preferable to notify the person in charge of the corresponding stored information if the related stored information is stored. According to Table 3, the first failure information and the third failure information are related failures because the failure location is the same as that of the belt.

In step 45, the controller measures the level of the failure information. That is, the controller analyzes the generated failure information and measures the level of the corresponding failure.

In step 46, the controller selects a warning group corresponding to the measured failure level. That is, different warning groups are selected depending on when the failure level is high and when the failure level is low.

In step 47, the controller notifies the warning information to the terminal of the user included in the selected warning group. The warning information transmitted to the user terminal may include a date and time of failure and a cause of the failure. In general, the warning information may be briefer than the failure information stored in the storage in consideration of the transmission capacity.

In step 48, the controller notifies the warning information to the warning group corresponding to the stored information. That is, according to Table 3, if the cause of failure is a power supply member, the warning information is notified to the warning group a.

4 illustrates a method of notifying warning information to a warning group according to a generated failure level. However, the control unit determines whether the same failure as the current cause of the failure has occurred before and a repair method for the corresponding failure is stored. If a repair method for the cause of the failure is stored, the controller may repair the currently occurring failure using the stored repair method. In this case, it is obvious that the warning information should be notified to the relevant warning group.

5 is another diagram illustrating an operation performed by a controller according to an embodiment of the present invention. Hereinafter, an operation performed by the control unit according to an embodiment of the present invention will be described in detail with reference to FIG. 5.

In step 50, the controller determines whether the action is completed with respect to the failure. That is, it is determined whether the person in charge completes the action according to the warning information transmitted from FIGS. 3 and 4. The control unit moves to step 51 if it is determined that the action has been completed for the failure, and moves to step 53 if it is determined that the action has not been completed for the failure.

In step 51, the controller determines whether information on an administrator who has responded to the failure is stored. That is, when the same failure occurred as the current cause of the failure, and the person in charge completes the action, information about the manager is stored. If it is determined that the information on the manager is stored, the control unit moves to step 52, and if it is determined that the information on the manager is not stored, the controller moves to step 55.

In step 52, the controller determines whether additional information input is requested from the user, and if the additional information input is requested, the controller stores the additional information requested by the user. Additional information may include the administrator who corrected the actual failure and the corrective action.

In step 55, the controller stores information about the warning group that transmitted the failure information, and moves to step 52.

In step 53, the controller raises the failure level by one if the failure occurred by the previously transmitted warning information. That is, if the previously selected fault level is level 2, the control unit raises the fault level to level 3.

In step 54, the controller notifies the warning information to the terminal of the user included in the selected warning group. The warning information transmitted to the user terminal may include a date and time of failure and a cause of the failure. In general, the warning information may be brief information compared to the failure information stored in the storage in consideration of the transmission capacity.
