Examples of the electronic signboard terminal 130

FIG. 2 is a block diagram showing a detailed configuration of a sign board operating terminal 130 according to an embodiment of the present invention.

2, the electric billboard operating terminal 130 according to an exemplary embodiment of the present invention includes an operation state collecting unit 131, a screen information generating unit 132, a contents managing unit 133, a screen managing unit 134, An information display unit 135, a failure determination unit 136, a restoration execution unit 137, an air conditioning system management unit 138, a panel management unit 139, a temperature management unit 140, a power management unit 141, 142).

The operation state collecting unit 131 according to the present invention includes an air conditioning control module 111, a contents control module 112, a screen control module 113, a panel control module 114, And collects fault information and control history information generated in at least one of the communication control module 115, the power control module 117, and the temperature control module 116. [

For example, in the case of the air conditioning control module 111, the operation state collecting unit 131 acquires failure information (physical information, for example, on-off information) from the air conditioning control module 111 that controls the operation of the cooling fan or the air conditioner And collects signal data exchanged between the cooling fan and the air conditioning control module 111 as control history information.

Similarly, the operation state collecting unit 131 according to the present invention includes a content control module 112, a screen control module 113, a panel control module 114, a power control module 117 (For example, on-off information) from the communication control module 115 and the temperature control module 116 as control history information.

For example, it may include color temperature, brightness, and color correction measured from the screen control module 113 where color temperature, brightness, and color correction for the screen is performed, or may include identification information and position information specific to each module.

In this way, the control history information includes all the data exchanged between the object and the control module, for example, the temperature measurement result with time and the speed of the cooling fan or the air conditioner related to the temperature control. Also, Location information, identification information, and the like. Thus, the control history information has a broader meaning than a conventional control signal.

Next, the screen information generating unit 132 according to the present invention recognizes that the fault information is not collected from the operation state collecting unit 131, And generates screen information combining image and character information. The form of the generated screen information is shown in FIGS. 4 and 5. FIG.

Next, the content management unit 133 according to the present invention transmits the screen information generated by the screen information generation unit 132 differently for each content control module 112, and according to the intention of the operator, And transmits the information to the content control module 112.

In the past, such a mechanism has not been provided.

Here, it is preferable to transmit the generated screen information to the content control module 133 every predetermined time (scheduling time) or whenever an operator generates an event (generated by a user's request). By sending the screen information at the scheduling time or event occurrence, diversity of information expression can be given by reflecting the unique characteristics of the LED display board. On the other hand, the screen information transmitted to the content management unit 133 is scattered on the screen of the screen under the control of the content management unit 133. [

Next, the screen management unit 134 according to the present invention detects the color temperature of the screen of the LED display board 110 adjusted by the operator as the normal state is recognized when failure information is not collected in the operation state collector 131, And transmits color information including brightness and color correction to the screen control module 113.

Since a plurality of LED elements are arranged on the screen or have a discharge cell structure, the color information including the color temperature, the brightness, and the color correction may be adjusted so that the screen information displayed on the screen of the LED display panel 110 may be more clearly displayed .

Next, the information display unit 135 according to the present invention plays a role of deriving the location information and the identification information from the control history information together with the fault information when the operation state collector 131 collects the fault information. Thus, the operator responsible for the display board operating terminal 130 can monitor the LED display boards 110 located at different positions even at a long distance.

Next, the failure determining unit 136 determines whether the corresponding control module is a physical failure or a software failure based on the failure information and the control history information collected by the operation state collecting unit 131 . In the case of a physical failure of the LED electric sign board 110, the repair person immediately dispatches the control panel to replace the corresponding control module of the LED sign board 110. However, when it is confirmed as a software failure, the next recovery execution unit 137 is operated.

If the failure determination unit 136 determines that the failure is a software failure, the recovery execution unit 137 generates recovery information for the cause and outputs the recovery information to the LED electronic sign 110 (110) based on the location information and the identification information. To the corresponding control module. Accordingly, the control module of the LED display board 110, which is easily disturbed even at a remote place, can be quickly restored, and the recovery time and cost can be greatly reduced.

Next, the air conditioner management unit 138 according to the present invention controls the air conditioner control unit 111 such that when the speed and the set time of the cooling fan provided in the LED electronic board 111 and the temperature size of the air conditioner are adjusted based on the control history information of the air conditioning control module 111 And transmits the generated air conditioning information to the air conditioning control module 111 of the LED display board 110. The air-conditioning information is not limited to a cooling fan or an air-conditioner, and may contain information related to other types of air-conditioning devices.

Next, the panel management unit 139 according to the present invention adjusts the brightness (brightness), pixel pitch and resolution of the panel provided on the LED electronic board 111 based on the control history information of the panel control module 114 And transmits the generated panel color information to the panel control module 114. At this time, the panel is an adjunct to the LED display panel which exists adjacent to or disposed on the screen of the LED display panel 110 or exists on the other surface to maintain the inherent brightness or resolution so as to be easily recognized by the public.

Next, the temperature management unit 140 according to the present invention generates the adjusted temperature information based on the control history information of the temperature control module 116, and transmits the generated temperature information to the temperature control module 116. The transmitted temperature information is supplied to the inside of the LED electric sign board 110 under the control of the temperature control module 116. As a result, it is possible to safely preserve the LED electric signboard 110, which is affected by the high or low temperature, thereby prolonging the service life.

Next, the power management unit 141 according to the present invention generates the adjusted voltage information based on the control history information of the power control module 117 and transmits the generated voltage information to the power control module 117.
