Description

Disaster warning and information signage by redundant power source and data processing method

The description below relates to electronic devices for disaster warning and information signs.

Recently, with the rapid development of intelligent digital imaging devices based on LCD, LED, etc., digital signage is becoming common, and the demand for digital signage is due to the fact that it is possible to communicate in two-way rather than one-way advertisement media. and the market is showing rapid growth. However, the existing digital signage only displays preset contents and advertisements, and when a disaster occurs, it does not have a function to detect, analyze, and notify the outside. There were problems in that the installation cost was high and power consumption was high. In addition, in the event of a disaster, if the existing communication network and power are cut off, disaster information cannot be provided to the residents of the disaster area.

Accordingly, there is a need for a technology capable of quickly disseminating an emergency or disaster situation to a large number of people using digital signage and preparing for a disaster or accident in the relevant area.

In the event of a disaster, communication is possible even if the communication network is paralyzed, so that it is possible to provide an electronic device that continuously delivers a disaster alert.

An electronic device for a disaster warning and guidance sign includes: a sensing unit configured to detect mode information including a disaster occurrence mode and a daily life mode according to whether a disaster has occurred; a duplication data processing unit duplicating data corresponding to the sensed mode information; and a display unit for displaying disaster data related to the disaster occurrence mode from the duplicated data on a display area whose size is adjusted based on the disaster occurrence mode when the sensed mode information is a disaster occurrence mode.

The sensing unit includes determining whether the electronic device is powered on or communication is connected according to detecting the disaster occurrence mode, and the redundant data processing unit includes general data related to the daily life mode and disaster related to the disaster mode and duplicating data, wherein the display unit outputs, in the case of the daily life mode, image content, fine dust, or weather information for the daily life mode through the entire display area, and in the case of the disaster occurrence mode, the A display area of the electronic device is reduced to a preset size, power is supplied through a battery connected to the electronic device, and disaster data corresponding to the disaster occurrence mode is displayed on the reduced display area, and a warning light connected to the electronic device , it is possible to spread the disaster situation through a speaker and an alarm.

In the disaster occurrence mode, when power to the electronic device is cut off, the redundant processing unit configures a disaster message related to disaster data corresponding to the disaster occurrence mode transmitted remotely using an auxiliary power supply device, and In the occurrence mode, when communication to the electronic device is cut off, a disaster message related to disaster data corresponding to the disaster occurrence mode stored therein may be configured using internal memory power.

The electronic device always charges a battery with energy obtained from an auxiliary power supply to the electronic device as a DC voltage, and when the battery of the electronic device is cut off from power to the electronic device, it is used as an auxiliary power source to manage the battery When battery operation is performed through battery-related overvoltage and overcurrent control and temperature control by the system (Battery Management System), and communication or power to the electronic device is cut off, the solar power charged in the battery using the auxiliary power device An operation for outputting disaster data corresponding to the disaster occurrence mode may be performed based on the energy.

The electronic device further includes a thermal imaging camera, CCTV or sensor, and detects smoke, temperature, and heat around the electronic device using a thermal imaging camera, CCTV or sensor connected to the electronic device in the daily life mode, The auxiliary power supply includes a device for generating renewable energy, and stores solar energy obtained from a solar panel in the daily life mode in the electronic device in a battery, and the display unit detects the disaster occurrence mode if necessary, outputting a disaster message related to the disaster data to a display area whose size is adjusted based on the disaster occurrence mode using solar energy stored in the battery, wherein the solar panel includes the electronic device It is installed within a preset distance and the solar panel is installed in a specific direction, and may be adjustable in a direction including up, down, left, and right.

When external power is cut off due to a disaster, it is possible to reduce the spread of disaster damage by providing a disaster warning to residents living in disaster areas and remote areas without using external power.

In the event of a disaster, disaster alert information can be output on the digital signage and information broadcasts are sent through speakers and warning lights, so that the disaster situation can be quickly communicated to the residents of the disaster area.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings.

FIG. 2 is a diagram for describing a general operation of an electronic device according to an exemplary embodiment.

Referring to FIG. 1 , it is a structure of a general disaster warning system. When a disaster occurs, the public disaster warning delivery system uses the terrestrial communication network. Therefore, it is ineffective when the terrestrial communication network used in the public disaster alert delivery system is paralyzed in the disaster area. In addition, all current disaster warning delivery systems are managed using external power. When the terrestrial communication network is paralyzed or power is cut off due to a disaster, there is no way to deliver a disaster alert to the residents of the disaster area.

Referring to FIG. 2 , the electronic device 100 may provide an emergency electronic display board or an information electronic display board. The electronic device 100 may provide a guide image and a promotional image for each region through an information display board in normal times, and may be converted to a disaster electronic display board in case of a disaster to provide a message such as 'evacuation wind'. In normal times, information such as content, fine dust, and weather can be delivered through the display. In the event of a disaster, disaster alert information can be displayed on the display (electric signboard) and announcements are sent through speakers and warning lights, so that the disaster situation can be quickly communicated to the residents of the disaster area. For example, it is possible to store solar energy without an external power facility and use the stored solar energy as a secondary battery (battery) power to minimize current consumption used in displays, speakers, and warning lights to operate for a long time even in cloudy weather. have.

The electronic device according to an embodiment may provide help to prevent damage to residents of the disaster area from increasing by delivering prompt and continuous action guidelines and evacuation guide information even after a disaster occurs.

The electronic device according to an embodiment may provide such that disaster information can be delivered immediately even in an island or remote area where terrestrial communication service is not smooth.

The electronic device according to an embodiment may first detect a disaster occurrence and transmit disaster information to the control center.

3 is a diagram for describing an operation of a daily life mode in an electronic device according to an exemplary embodiment.

A hardware configuration of the electronic device 100 will be described. The electronic device 100 includes a main controller 301 , an LED controller 302 , a disaster main controller 303 , a disaster LED controller 304 , an LED modem 305 , a battery 306 , a BMS 307 , and solar power. It may include a panel 308 and an LED billboard 309 . In this case, the electronic device 100 may include various hardware components in addition to the above-mentioned hardware components.

The electronic device 100 may operate in a different hardware configuration according to the daily life mode and the disaster occurrence mode. 3 , the daily life mode will be described.

The main controller 301 may manage the schedule and store the displayed image transmitted from the LTE modem 305 . The main controller 301 may adjust an on/off time. The main controller 301 may transmit an image signal to the LED controller 302 .

The LED controller 302 may control image signal transmission, brightness adjustment, color temperature, and the like to the LED signboard (display) 309 .

The disaster LED controller 304 may connect the 6-module data signal to the 6-module by bypassing the LED controller in normal times.

The LED signboard 309 may transmit a signal to match the transmitted signal to the LED module.

For example, in the case of a normal daily life mode, the electronic device 100 may output image content, fine dust, or weather information to the entire display area. At this time, the LED signboard 309 becomes a guide signboard using the entire display area, and may output a guide image or a promotional image for each region in the form of content. In addition, in the daily life mode, information such as fine dust and weather may be transmitted through the LED display 309 .

Referring to FIG. 4 , it is a diagram for explaining the operation of the disaster occurrence mode.

The solar panel 308 may charge the battery during normal times. The solar panel 308 may have overvoltage, overcurrent and temperature control by the BMS 307 in case of a disaster. The photovoltaic panel 308 may apply power when the power is always turned off (automatic power check).

The disaster master controller 303 may store an image displayed in case of a disaster transmitted from the LTE modem 305 . The disaster master controller 303 may adjust the on/off time. The emergency main controller 303 may transmit an image signal to the emergency LED controller 304 .

The disaster LED controller 304 may transmit a 6-module disaster data signal to the LED signboard 309 . Disaster LED controller 304 may generate a speaker and alert alarm.

In the case of a disaster, only 6 modules of the LED signboard 309 can be connected to the solar power source. The LED signboard 309 may transmit the transmitted signal according to the 6 modules.

For example, in preparation for a disaster occurrence mode in the electronic device 100 , the battery may be constantly charged with a DC voltage from the solar panel 308 . In this case, the solar panel 308 may be fixedly installed in a direction that the sun enters well. For example, the position of the solar panel may be automatically or manually adjusted in a preset time unit. In addition, the position of the solar panel may be adjusted in a preset time unit according to the season. In addition, since the solar panel can acquire solar energy only during a preset time when sunlight is present, the solar panel does not operate at times other than the preset time. The battery is used as an auxiliary power source when the main power is cut off, and the battery-related overvoltage and overcurrent control and temperature control are performed by the BMS 307 to perform safe battery operation. In this case, the replacement cycle of the battery (LI-lon 12V/130AH) may be replaced if a problem occurs during charging or checking a plurality of times (eg, 400). It can be used for both constant power (AC power) and regular power operation is a common technique, so it is not described separately.

The disaster main controller 303 has data that can be displayed in the disaster LED controller 304 when the main power is cut off, and transmits it only in a specific color (eg, red) in the display area set in response to the disaster occurrence mode ( low power consumption) can be displayed. In other words, disaster data can be displayed in red for low-power usage. The LED sign 309 may be configured to be lit only in red color within 6 characters (6 modules). In the main controller 301, general images, fine dust, and weather information are normally displayed, and when disaster information is received, the warning light is turned on while displaying the disaster information on the LED display board, and it can be notified through a loudspeaker (speaker). In case of a disaster, power is supplied from the solar battery when the main power is cut off, and the disaster message is displayed on the reduced display area through the LTE modem 305, and the disaster situation can be propagated through a speaker and an alarm. In this case, the reduced display area may mean an area in the middle of the LED signboard 309 .

5 is an example of an electronic device according to an embodiment.

The digital signage 140 is an advertisement using a digital information display (digital 　information 　display, 　DID), and refers to a billboard that can control advertisement contents through a communication network in the control center. It is commonly found in subway stations, bus stops, apartment elevators, banks, and other places with a lot of floating population. For example, there are types of digital signage such as outdoor digital signage installed on an exterior wall of a building or an electronic signboard, and a small indoor digital signage installed on an inner wall of a large shopping mall or made in the form of a billboard.

The electronic device 100 may always charge the battery with energy obtained from the auxiliary power supply to the electronic device as a DC voltage. In this case, energy obtained from the auxiliary power supply may be stored in the battery as much as the capacity of the battery. When the power to the electronic device is cut off, the battery of the electronic device may be used as an auxiliary power source and battery operation may be performed through battery-related overvoltage and overcurrent control and temperature control by a battery management system.

For example, when communication or power to the electronic device is cut off, the electronic device 100 outputs disaster data corresponding to the disaster occurrence mode based on solar energy charged in the battery using the auxiliary power supply device. can be performed. In this case, the auxiliary power supply may include a device for generating renewable energy. In an electronic device, solar energy obtained from a solar panel in a daily life mode may be stored in a battery. The solar panel may be installed within a preset distance from the electronic device, and the solar panel may be installed in a specific direction, and may be adjustable in directions including up, down, left, and right.

When a disaster situation occurs in a specific area (for example, in the vicinity of the electronic device), the electronic device 100 is self-contained without using external power in case of power cut off or communication cut off to the electronic device 100 . As a result, it is possible to deliver a disaster warning (disaster message) to the residents living in the disaster area using the electric energy stored using the solar panel. At the same time, the electronic device 100 not only outputs a disaster alert (disaster message) in the form of text data, but also outputs it as voice data through a speaker, so that residents living in the disaster area can be immediately notified of an emergency situation.

In addition, the electronic device 100 may reduce environmental pollution for energy production by using renewable energy called solar energy. Specifically, when a disaster situation occurs in a specific area, the electronic device 100 reduces the display area of the electronic device 100 and outputs a disaster alert to the reduced display area to spread disaster damage using minimal power. can reduce

CCTV, thermal imaging cameras, sensors, etc. can be additionally connected. For example, a camera may be inserted into the electronic device 100 in the form of a module, and a separate camera may be attached to the outside of the electronic device 100 . In addition, it may be connected in various forms. In this way, additional functions may be added to the electronic device 100 . The electronic device 100 may detect smoke, heat, etc. using a CCTV, a thermal imaging camera, and a sensor in a daily life mode. The electronic device 100 may directly determine whether a disaster situation has occurred in a corresponding area by using a CCTV, a sensor, etc., in addition to an indirect case in which communication to the electronic device 100 is cut off or power is cut off.
