The electric sign 10 is a device that provides information for various purposes in a visual (or audible way, etc.), for example, a VMS (Variable Message Sign) system of Korea Road Corporation, a destination of a railroad or subway. It is applied without limitation to various types such as information devices, airport FIDS (Flight Information Display System), check-in counters, public relations in various government offices, and civil petition information boards.

The local control device 20 is provided corresponding to each electronic sign 10, collects electronic sign operation information on the operation state of the sign 10, and performs self-diagnosis based on the operation information of the sign to determine failure. When it occurs, error information is generated and transmitted, and self-diagnosis and recovery are performed according to the corresponding recovery plan information.

The local control device 20 can be configured in various ways, for example, as shown in FIG. 1, a communication module 21, a state collection module 23, a control module 25, and a local fault. May contain recovery information.

The communication module 21 transmits and receives data to and from the electronic board 10 and the electronic board operation server 30.

The state collection module 23 collects the operation information of the electronic board. The state collection module 23 may include a variety of sensors, for example, a humidity sensor capable of detecting leakage of an electric sign, a current or voltage sensor capable of detecting an electric leakage, etc., each of the electric sign 10 A temperature sensor or the like capable of detecting an overheating condition at a location may be included, and values sensed through these various sensors are stored as operation information of the electric signboard.

The control module 25 determines whether or not there is a failure based on the operation information of the electric signboard, generates the failure information, performs self-diagnosis and restoration according to the restoration plan information, and accordingly the restoration completion information or the restoration impossible. Generate information.

In the control module 25, an appropriate value or an appropriate range for the detailed items of the operation information of each of the display boards is preset, so that the detection result for each detailed item collected by the state collection module 23 is the appropriate value or Whether it is in an appropriate range is checked to determine whether there is a disorder (S211 in FIG. 3).

When the control module 25 is out of an appropriate value or an appropriate range for the one or more detailed items, it determines it as a failure state, generates failure information, and transmits the failure information to the display operation server 30 (S212).

The failure information includes, for example, identification information of the display board 10 on which a failure is determined, the detailed item determined as a failure, or a failure code set therefor, and may additionally include information on the degree of failure.

The control module 25 then performs self-diagnosis and recovery according to the recovery plan information (S213).

The recovery plan information is information including a preset recovery method corresponding to the fault code. For example, a fan is operated for a fault code for a leak, or a power source for a fault code for a short circuit occurs. In the case of a fault code for overheating above an appropriate temperature, information on recovery measures such as turning off the system power supply is included. As for the recovery method, as long as the control module 25 can perform itself in addition to the above-described method, various methods may be applied without limitation.

Here, the recovery plan information is basically the control module 25 can perform self-diagnosis and recovery by receiving the recovery plan information stored in the failure recovery information from the electronic board operation server 30 to be described later, but depending on the setting Diagnosis and recovery may be performed by extracting the recovery plan information from the local failure recovery information stored in the local storage module 27.

The local fault recovery information is fault recovery information limited to a specific display board 10, and is stored in the local storage module 27 of the local control device 20, and identification information, fault code, and It means information including the recovery plan information.

On the other hand, the failure recovery information is for all the signboards 10 managed by the signboard operation server 30, and is stored in the database 31 of the signboard operation server 30, and types (classification) of all signboards 10 And identification information, a fault code, and information including the recovery plan information.

In any case, the local failure recovery information may be transmitted to the electronic board operation server 30 by the control module 25 to be updated and synchronized with the failure recovery information (S215).

Basically, the recovery plan information is extracted and received from the electronic board operation server 30 at the request of the control module 25, but depending on the setting, the control module 25 sends the recovery plan information to the electronic board operation server 30. Before requesting, the local storage module 27 may first extract the recovery plan information corresponding to the corresponding failure code to perform self-diagnosis and recovery.

In the latter case, when determining a failure, the control module 25 first extracts the restoration plan information corresponding to the failure information from the local failure restoration information, performs self-diagnosis and restoration accordingly, and returns the result to the local failure restoration information. The information may be updated, and the updated local error recovery information may be transmitted to the electronic board operation server 30 to update the error recovery information.

On the other hand, when the recovery plan corresponding to the error information requested by the control module 25 does not exist in the error recovery information or the local error recovery information, the display board operation server 30 controls the general recovery plan information. It can be transmitted to the module 25 so that self-diagnosis and recovery can be performed. (See S51 and S52 in Fig. 5)

Here, the general recovery plan information may be determined such that two or more recovery methods are performed in a set order.

The general recovery plan information includes, for example, ① PC power reset, ② fan operation, ③ power cut off due to a short circuit, and ④ system power cut off in case of voltage or current abnormality. Can be done. Here, it goes without saying that the type and order of the recovery plan can be variously changed as necessary.

In this case, the display board operation server 30 is when the recovery is completed according to any one of the recovery methods included in the general recovery plan information in the local control device 20 and the recovery completion information is received (S53 in FIG. 5 ). ), in response to the failure information, the recovery method may be generated as recovery plan information and updated in the failure recovery information (S54 in FIG. 5).

The local storage module 27 receives the updated failure recovery information for the display board 10 from the display board operation server 30 and stores it as local failure recovery information.

When the error information is received from any one of the local control devices 20, the electronic board operation server 30 extracts the recovery plan information corresponding to the error information from the stored error recovery information, and the local control device 20 Transfer to.

The failure recovery information includes the failure information including the failure code assigned according to the failure type and the identification number of the local control device 20 in which the failure has occurred, and the restoration method preset in response to the failure code. Include information.

In this case, when the recovery plan information corresponding to the error information does not exist in the error recovery information, the electronic board operation server 30 extracts pre-stored general recovery plan information as the recovery plan information, as described above. It is transmitted to the local control device 20.

Alternatively, when the restoration is completed according to the restoration plan information, the electronic board operation server 30 receives the restoration completion information generated by the local control device 20 and updates the failure restoration information.

The recovery completion information may be similarly stored in the local storage module 27 by the control module 25.

On the other hand, the electronic board operation server 30, when the recovery is not performed according to the recovery plan information, receives the unrecoverable information generated by the local control device 20 and updates the error recovery information to the alarm unit 33 It can be notified to the server operator through (S313 in FIG. 3).

The alarm unit 33 may be provided in various types, for example, may be provided on a screen provided in the electronic board operation server 30 by a warning alarm method, or may be provided with other visual devices such as a buzzer. , Or, the operator can be recognized through a personal terminal (smart phone or tablet PC) of the set operator.

In this case, the operator may transmit the failure information to the person in charge of recovery, and dispatch it to the site to restore or repair the electronic signage 10.

When the failure of the electronic signage 10 is restored through the above process, the operator or the person in charge of recovery, through the manager terminal (not shown) or the person in charge terminal, based on the received irrecoverable information, the failure information and the corresponding The recovery plan information may be additionally generated and added to the failure recovery information (S314).

The uninterrupted security controller 40 is connected to the display board operation server 30 and each local control device 20, and when a communication failure occurs between the display board operation server 30 and the local control device 20, the uninterrupted mode Switch to, so that failure recovery can be achieved.

Referring to Figure 2, the non-stop security controller 40, when a communication failure occurs, all external access except for each local control device 20 managed by the set manager terminal (not shown) and the electronic board operation server 30 Is blocked, and each local control device 20 transmits and receives the error information and the corresponding local error recovery information to and from each other so that self-diagnosis and recovery are performed.

Specifically, when a communication failure occurs in step S311 of FIG. 3 and the display board operation server 30 cannot manage each local control device 20, the uninterrupted security controller 40 enters the uninterrupted mode (S41 in FIG. 4). To switch, the non-disruptive mode basically blocks all external access except for the manager terminal and each local control device 20, and is activated so that each local control device 20 can perform the server role.

Specifically, the uninterrupted security controller 40 informs each local control device 20 of an abnormality of the signboard operation server 30 when a problem occurs in the display board operation server 30, and each local control device 20 serves as a server. The local control device 20 in which a failure has occurred transmits the failure information to the entire local control device 20 to request the recovery plan information.

Each local control device 20 that has received the error information checks the recovery plan information corresponding to the error information in the local storage module 27, and if any, transmits the recovery plan information to the corresponding It is transmitted to the local control device 20 so that failure recovery can be performed.

Here, the non-stop security controller 40, when communicating with each local control device 20, may check the identification information of each local control device 20 to allow communication between each local control device 20. .

Accordingly, even when an error occurs in the electronic board operation server, each local control device is activated by the uninterrupted security controller to perform the server role, so that the failure recovery operation can be performed without interruption.

On the other hand, the non-stop security controller 40, when the communication between the display board operation server 30 and each local control device 20 is restored, each local control device 20 is controlled by the display board operation server 30 Switching to the server operation mode, each local failure recovery information stored in each local control device 20 can be updated to the failure recovery information (S44 in FIG. 4).
