[0003] The present invention can be utilized for waste management, protection of public facilities, and smart environment monitoring. Background Technology

[0004] Most existing weather sensing technologies have relied on providing data by measuring temperature and rainfall individually. However, this approach has the disadvantage of making real-time response difficult and preventing immediate reactions to environmental changes. Furthermore, existing systems lack the ability to intuitively visualize data, making it difficult for users to understand immediately.

[0005] In particular, in waste collection and storage systems, the problem of waste contamination due to rainfall can occur, and to prevent this, cumbersome measures such as manually closing lids or covering them with plastic are required. However, these methods are difficult to apply in real time and require additional labor.

[0006] Therefore, a system is required that comprehensively analyzes temperature and rainfall data to display the status in real-time via LEDs, and automatically activates a rain barrier to protect waste when rainfall occurs. Additionally, it is necessary to enhance visual feedback and enable rapid response by utilizing LED indicators to intuitively provide users with environmental conditions. Through such a system, the efficiency of waste management can be improved, and environmental pollution caused by rainfall can be prevented.

[0007] In this regard, examining conventional technology, a 'multi-purpose performance facility' is disclosed in Korean Registered Patent No. 10-0970007 and a 'blower having a rainwater inflow prevention function utilizing a rain sensor' is disclosed in Korean Registered Patent No. 10-1862055, but these fail to solve the aforementioned problems.

[0011] Upon detection of rainfall, the rain barrier installed on the top of the roll-off box is automatically activated immediately to prevent waste from being contaminated by rainwater.

[0012] The LED indicator is linked with the rain detection function to allow users to intuitively understand the environmental conditions.

[0013] It enables remote monitoring of environmental conditions through IoT (Internet of Things) functionality, allowing users to check the operation status of the barrier in real time and control it remotely.

[0014] It adjusts the opening and closing speed of the barrier according to the rainfall detection intensity and provides an automatic locking function if rainfall is detected for a certain period of time.

[0015] The stability of the system is ensured by adding a wind speed sensor capable of detecting wind intensity, thereby restricting the opening and closing of the barrier during strong winds.

Specific details for implementing the invention

[0033] Specific details regarding the problem to be solved, the means for solving the problem, and the effects of the invention as described above are included in the embodiments and drawings to be described below. The advantages and features of the present invention, and the methods for achieving them, will become clear by referring to the embodiments described in detail below in conjunction with the accompanying drawings.

[0035] The present invention provides an LED display and rain barrier operation system linked with a temperature and rainfall detection sensor, which analyzes real-time environmental data using a temperature and rainfall detection sensor, visually displays the results using an LED, and includes a rain barrier that operates automatically when rainfall is detected.

[0036] In addition, the LED display and rain barrier operation system linked with the temperature and rainfall detection sensors of the present invention can be applied to roll-off containers, modified container boxes, concrete boxes, or steel boxes used for storing waste, but is not limited thereto. Furthermore, according to the technical configuration of the present invention described above, it can be applied to devices that require protection from rainfall or can be opened for ventilation depending on whether rainfall is detected.

[0037] To this end, the present invention includes an arm roll box (100), a microcontroller (not shown), a control box (200), and an LED display module (300).

[0039] It will be obvious that the above roll-off box (100) is configured as a box that has a receiving space inside to collect waste and is connected to a roll-off truck on one side for transport.

[0041] The above microcontroller is configured to be embedded inside the control box (200) and to be linked with an IoT module to transmit and receive environmental data.

[0042] It is configured to analyze sensor data in real time, control the LED display module (300) and the rain barrier (410) below, and support remote monitoring through IoT functions.

[0043] As an example, the microcontroller may be configured as an 8-bit AVR (Alf and Vegard's RISC processor). The 8-bit configuration has a simple structure and limited performance in complex mathematical operations due to the characteristic that the word length is limited to 8 bits.

[0044] In addition, AVRs have very strong electrical characteristics, so the current limit that their pins can supply or receive is higher compared to other microcontrollers.

[0045] In addition, simple arithmetic operations can be performed on temperature and rainfall measurements, and the blocking drive module (400) and LED display module (300) can be triggered accordingly. For example, among 8-bit microcontrollers, a PIC (Peripheral Interface Controller) may be configured, and if additional computational functions are required, among 16-bit microcontrollers, a PIC 24 (Peripheral Interface Controller 24) or a dsPIC (Digital Signal Interface Controller), which is a DSP (Digital Signal Processor) version of a PIC, may be configured, and among 32-bit microcontrollers, an AVR 32 (Atmel AVR 32-bit), a PIC 32 (Peripheral Interface Controller 32), or an ARM Cortex-M series (Advanced RISC Machines Cortex-M series), may be configured, but is not limited thereto and may be configured with various microcontrollers.

[0047] The above control box (200) is placed on one side of the above roll-off box (100).

[0048] The above control box (200) serves as a case and is intended to protect the electronic components embedded inside from the external environment.

[0049] In an example, the control box (200) is configured to include a temperature sensing sensor (not shown), a rain sensing sensor (not shown), a power supply (not shown), and the microcontroller in an internal receiving space.

[0050] The temperature sensing sensor is configured to be positioned through one side of the control box (200) and to be able to measure the temperature.

[0051] The above temperature sensing sensor measures the temperature, transmits data to the microcontroller, and changes the LED color according to the temperature.

[0052] As an example, it may be configured as a digital temperature sensor. For instance, it may be configured as a thermistor temperature sensor, a thermocouple temperature sensor, a resistance temperature sensor, a semiconductor temperature sensor, or a bimetal thermometer, but is not limited thereto and may be configured as various temperature sensing sensors.

[0053] The above rain detection sensor is configured to be positioned through one side of the control box (200) and to detect rain.

[0054] The above rain detection sensor detects whether rain is occurring, transmits a signal to the microcontroller, and triggers an LED warning and the operation of a rain barrier (410) when rain occurs.

[0055] As an example, it may be configured as a resistive rainfall detection sensor. For instance, it may be configured as a capacitive rainfall detection sensor, an optical rainfall detection sensor, an ultrasonic rainfall detection sensor, or a radar rainfall detection sensor, but is not limited thereto and may be configured as various rainfall detection sensors.

[0056] The above power supply unit is configured to be placed inside the control box (200) to drive the entire system.

[0057] As an example, it may be composed of a secondary battery. For instance, it may be composed of a fuel cell, but is not limited thereto and may be composed of various power supply devices.

[0058] The above control box (200) may be configured to further include a wind speed detection sensor (not shown).

[0059] The above wind speed detection sensor is configured to be positioned through one side of the control box (200) and to be able to measure wind speed.

[0060] The above wind speed detection sensor measures the wind speed and transmits data to the microcontroller, and triggers the following locking part (not shown) according to the wind speed.

[0061] In an example, when a wind speed of 1 m / s is measured, the microcontroller issues a command to make the following lock unnecessary to operate, and when a wind speed of 10 m / s is measured, the microcontroller issues a command to operate the following lock. Additionally, after the following lock is operated, if the wind speed is measured to be 5 m / s or less, the microcontroller issues a command to unlock the following lock. The wind speed detection range is not limited to 5 m / s or 10 m / s, but can be varied as the user changes the detection range.

[0063] The above LED display module (300) serves to visually display temperature and rainfall conditions, and is configured so that environmental conditions can be intuitively checked through LED colors.

[0064] Specifically, the LED display module (300) is configured to display LED colors such as red, green, or blue in the RGB series, so that an operator can visually confirm them. Additionally, it is configured to display orange, yellow, etc. through a color combination of red, green, and blue in the RGB series.

[0065] In an example, blue indicates stability, green indicates caution, and red indicates danger. When the LED indicator module (300) appears in blue, the operator can check this and detect that the current state is stable. When it appears in green, the operator can check this and confirm that the current state requires caution, and when it appears in red, the operator can check this and confirm that the current state is dangerous.

[0066] The above LED display module (300) provides immediate notification by blinking the LED or changing the color when rain is detected.

[0067] As an example, it may be composed of an LED single-color display module, and may be composed of, for example, an LED multi-color display module, an LED character display module, an LED graphic display module or an LED strip module, but is not limited thereto and may be composed of various LED display modules (300).

[0069] The above barrier drive module (400) is configured to be positioned on one side of the above roll-off box (100).

[0070] The above barrier drive module (400) is configured to include a rain barrier (410), a drive unit (420), and a locking unit (not shown).

[0071] The above rain barrier (410) is positioned on the top of the roll-off box (100) and is configured in the form of a cover that can open and close the top of the roll-off box (100).

[0072] In an example, the above roll-off box (100) may be composed of a cover unit, etc., that covers the above roll-off box (100). For example, it may be composed of a metal plate, a plastic plate, a roof tarp, a tent, etc. The above roll-off box (100) may be operated to cover the top of the above roll-off box (100) from left to right, from right to left, from front to rear, and from rear to front, but is not limited thereto and may be composed of various cover shapes and covering methods.

[0074] The above driving unit (420) is connected to the above rainwater barrier (410) and is configured to be positioned on one side of the above roll box (100) to drive the above rainwater barrier (410).

[0075] More specifically, it includes an actuator that automatically opens and closes the barrier upon detection of rainfall, and is configured to adjust the opening and closing speed according to the rainfall intensity.

[0076] The above drive unit (420) may be configured as a pneumatic drive unit as an example. For instance, it may be configured as a hydraulic drive unit, a DC motor, a servo motor, a stepping motor, a solenoid unit, or a gear and link combination unit, but is not limited thereto and may be configured as various drive modules.

[0077] The above locking part is configured to be positioned on one side of the above roll box (100) and to be able to lock or unlock the barrier drive module (400) according to the measured threshold value of the wind speed detection sensor.

[0078] In an example, the actuator of the barrier drive module (400) may be configured to be in contact with or separated from the barrier drive module (400) so as to be locked or unlocked. For example, it may be configured to be locked and unlocked in a ring type, a hook type, or a pinch type, but is not limited thereto and may be configured in any form that can fix the following barrier (410).

[0080] The configuration, excluding the above roll box (100) and power supply, is controlled by the microcontroller.

[0081] This is so that the above-mentioned roll-off box (100) performs the role of a box, the above-mentioned power supply device is configured to supply power to the entire system, and the remaining system excluding this is intended to operate the opening and closing of the LED display module (300) and the rain barrier (410) in conjunction with the result value measured from the external environment.

[0083] Meanwhile, among the expressions for rainfall defined in the present invention, examples of light rain, heavy rain, normal rain, and very heavy rain are shown in Table 1 below, and the definitions, descriptions, and quantitative values ​​thereof are based on data specified in the Korea Meteorological Administration.

[0084] Types of precipitation light rain Usually rain heavy rain very heavy rain standard Less than 3mm / h Less than 3~15mm / h Less than 15~30mm / h 30mm / h or more 1mm If you get rained on for an hour without an umbrella, your clothes will get slightly wet. 10mm The degree to which your clothes get soaked if you stand in the rain for an hour without an umbrella 30mm It is difficult to block the rain with an umbrella.

[0085] In addition, the range of wind speeds defined in the present invention is exemplified in Table 2 below, and the definition, explanation, and quantitative values ​​thereof are measured within the range of standards notified by the Korea Meteorological Administration.

[0086] Types of wind speed standard Slightly strong wind Wind speed less than 4~9 m / s strong winds Wind speed less than 9–14 m / s very strong winds If wind speed is expected to reach or exceed special alert levels

[0087] Hereinafter, the operation steps of an LED display and rain barrier operating system linked with a temperature and rain detection sensor according to the present invention will be described.

[0088] The LED display and rain barrier operation system linked with temperature and rain detection sensors according to the present invention comprises an information collection step (S100), an information judgment step (S200), and a module driving step (S300).

[0089] The above information collection step (S100) is a step that includes a temperature measurement step (S110) and a rainfall detection step (S120).

[0090] The above temperature measurement step (S110) is a step of measuring the temperature and transmitting the measured value to a microcontroller.

[0091] The temperature range measures from -10℃ to 50℃. Since the typical living environment temperature in most parts of the world ranges from -10℃ to 50℃, this represents the widest range for the universality of the temperature measurement sensor.

[0092] In the example, the temperature can be measured in three ranges: 10°C or lower, 11°C to 30°C, and 31°C or higher. However, the range is not limited to this and can be varied to various ranges, such as 5°C or lower, 6°C to 25°C, and 26°C or higher.

[0093] The above rainfall detection step (S120) is a step of measuring rainfall amount and transmitting the measured value to a microcontroller.

[0094] The above rainfall detection step (S120) measures within the range of 0 mm / h to 50 mm / h. This is to ensure that the rainfall amount notified by the meteorological agency is measured in mm per hour and within the notified range.

[0095] The above information collection step (S100) may further include a wind speed measurement step (S130).

[0096] The above wind speed measurement step (S130) is a step of measuring the wind speed and transmitting the measured value to a microcontroller.

[0097] The above wind speed measurement step (S130) measures in the range of 0 m / s to 30 m / s. This is to ensure that the wind speed announced by the meteorological agency is measured in units of meters per second and measured within the announced range.

[0099] The above information judgment step (S200) is configured to include a judgment step (S210) in which the microcontroller synthesizes the received information to determine the environmental state.

[0100] Specifically, the judgment step (S210) is a step of determining the current weather condition by combining the value measured in the temperature measurement step (S110) and the value measured in the rainfall detection step (S120).

[0101] Through the above judgment step (S210), it is determined whether precipitation is currently detected or not, and if precipitation is not detected, it is determined what the current temperature is.

[0102] The above information judgment step (S200) may further include a notification step (S220) and an information provision step (S230).

[0103] The above notification step (S220) is a step of providing a notification to the user when rainfall is detected.

[0104] The above notification step (S220) is a step of providing a notification when the user-specified range is reached, because the microcontroller is linked with IoT.

[0105] As an example, when rainfall is detected, a notification may be provided to the user's terminal. For instance, a notification may be provided to the user when the temperature is measured to be 3℃ or lower, but is not limited thereto, and the range of the notification may vary.

[0106] The above information provision step (S230) is a step of providing information so that the user can detect the LED status and whether the rain shield (410) is operating in real time through a mobile application or web interface.

[0107] The above information provision step (S230) is intended to allow the user to determine the display status of the LED display module (300) and whether the rain barrier (410) is operating in real time, even when the user is not present at the site.

[0108] This is intended to perform repairs or maintenance on malfunctions or non-operation caused by failures of the present invention, and to allow the user to monitor the on-site situation in real time.

[0110] The above module driving step (S300) is configured to include a display step (310) and an opening / closing step (S320).

[0111] The above display step (S310) is a step in which the microcontroller transmits the determined information to the LED display module (300) to change and display the LED color.

[0112] This is a step in which the LED color changes according to the rainfall detection intensity, and the LED blinks when the rainfall detection signal exceeds a specific threshold, allowing the user to immediately recognize it.

[0113] As an example, when the rainfall detection intensity is 1.5 mm / h or higher, the orange LED may blink every 2 seconds, and when it is 20 mm / h or higher, the red LED may blink every 1 second. However, this is not limited to this, and the settings may vary, such as when the rainfall detection intensity is 1.0 mm / h or higher, the orange LED may blink every 2 seconds.

[0115] The above opening / closing step (S320) is a step in which the microcontroller transmits the determined information to the barrier driving module (400) to selectively open / close the rain barrier (410).

[0116] When rain is detected, if rain continues for a certain period of time, the rain barrier (410) automatically locks after covering the roll-off box (100). Additionally, when rain detection stops and a certain period of time elapses, the rain barrier (410) returns to its original state.

[0117] This is to prevent contamination of the inside of the roll-off box (100) by rain, and to automatically open and close the rain barrier (410) even when the user is not present at the site, and to protect the roll-off box (100) through the rain barrier (410) until the rain stops.

[0118] Additionally, the opening / closing step (S320) may further include an automatic locking step (S330) in which the opening / closing of the barrier is restricted when the wind speed through the wind speed measurement step (S130) exceeds a specific threshold, and the barrier is switched to an automatic locking mode when there is a risk of damage to the barrier due to strong winds.

[0119] This is to protect the control box (200), etc., connected to the barrier drive module (400) through the above automatic locking step (S330), and to protect the waste stored inside the roll-off box (100).

[0120] Specifically, the structure of the rain barrier (410) has a shape with a very large surface area compared to its volume, so it is greatly affected by wind, and as a result, tearing, damage, or bending may occur due to strong winds. This is because it can cause failure by worsening the connection structure and lifespan between parts.

[0121] Additionally, the above opening / closing step (S310) may further include a manual opening / closing step (S311) in which a user manually opens / closes the barrier in real time.

[0122] The above manual opening / closing step (S311) is a step provided to allow the rain barrier (410) to be opened / closed manually when the opening / closing of the rain barrier (410) is restricted due to a malfunction or non-operation caused by a breakdown.

[0123] The above display step (S320) is a step in which the microcontroller transmits the determined information to the LED display module (300) to change and display the LED color.

[0124] The above display step (S320) is a step in which the LED color changes according to the rainfall detection intensity, and when the rainfall detection signal exceeds a specific threshold, the LED blinks so that the user can immediately recognize it.

[0125] As an example, when the rainfall detection intensity is 1.5 mm / h or higher, the orange LED may blink every 2 seconds, and when it is 20 mm / h or higher, the red LED may blink every 1 second. However, this is not limited to this, and the settings may vary, such as when the rainfall detection intensity is 1.0 mm / h or higher, the orange LED may blink every 2 seconds.

[0127] Hereinafter, a method for linking the LED display module (300) and the rain detection function of the present invention is described. In the present invention, the LED display module (300) and the rain detection function are controlled in real time through a microcontroller, and the LED color and flashing pattern are adjusted according to whether rainfall is detected.

[0128] Specifically, the method of linking the LED display module (300) and the rain detection function of the present invention is operated by linking through the connection configuration of the rain detection sensor and the microcontroller, the LED operation configuration according to whether rain is detected, the linkage configuration of the LED display module (300) and the rain blocking screen (410), and the system response speed configuration.

[0130] First, we will explain the connection configuration between the rain detection sensor and the microcontroller.

[0131] The rain detection sensor provides analog or digital output and recognizes rain when the rain detection value exceeds a specific threshold. Additionally, the microcontroller continuously reads the sensor values ​​to perform rain detection.

[0132] At this time, the threshold value can be optionally set as a reference value. For example, if the threshold value is set to 100, it is recognized as raining when it exceeds 100, and if the threshold value is set to 300, it is recognized as raining when it exceeds 300.

[0134] Next, the LED operation configuration based on rainfall detection is explained.

[0135] In detail, the LED color and lighting or flashing operation when rain is not detected, and the LED color and lighting or flashing operation when rain is detected, are explained through the following examples.

[0136] If rain is not detected, the LED lights up according to the temperature condition.

[0137] When the temperature is 10℃ or lower, a blue LED lights up; when the temperature is 11~30℃, a green LED lights up; and when the temperature is 31℃ or higher, a red LED lights up.

[0138] When rainfall is detected, it can be classified as light rain, moderate rain, or heavy rain.

[0139] When light rain is detected, the LED flashes orange to indicate that rain is falling. In this case, if the rain detection sensor detects rainfall of 1.5 mm or more, the LED flashes at 2-second intervals.

[0140] Normally, when rain is detected, the LED flashes yellow to indicate interest in the rain. In this case, if the rain detection sensor detects a rainfall amount of 3 mm or more, the LED flashes at 2-second intervals and activates the rain barrier (410), and if it detects a rainfall amount of 5 mm or more, the LED flashes at 2-second intervals and secures the closed rain barrier (410).

[0141] When heavy rain is detected, the LED flashes red to indicate the rainfall status as a warning. At this time, if the rainfall detection sensor is between 15mm / h and 20mm / h, the LED remains fixed in red, and if it exceeds 20mm / h, the LED flashes rapidly at 1-second intervals.

[0143] Next, the interconnected configuration of the LED and the rain shield (410) will be described.

[0144] If rainfall detection persists for more than 3mm, the microcontroller sends a command to close the rain barrier (410).

[0145] During this process, the LED changes to a yellow flashing state to indicate that the rain barrier (410) is in operation due to rain. When the barrier is completely closed, the LED remains in a fixed yellow state.

[0146] When the rainfall detection value decreases for 10 minutes after the rain stops, the barrier opens automatically and the LED returns to a color reflecting the original temperature state.

[0148] Next, the system response speed configuration is described.

[0149] The LED color changes within 1 second after rain is detected.

[0150] If rainfall of 3 mm or more is detected, the rain barrier (410) is closed within 3 seconds.

[0151] The barrier opens 10 minutes after the rain stops.

[0152] Through this method, LED indicators and rain detection functions are integrated to provide real-time visual warnings to users and, if necessary, automatically activate barriers to protect waste or facilities.

[0154] The following examples are presented to aid in understanding the LED indicator and rain detection functions of the present invention. However, the following examples are provided merely to facilitate a better understanding of the present invention and do not limit the present invention to the following examples.

[0156] I. Example. Experiment on Interlocking of LED Indicator and Rain Detection Function

[0157] In this embodiment, the operation of a system linked with a rain detection sensor and an LED display module (300) in an actual environment was measured.

[0158] 1) Experimental Conditions and Environment

[0159] (1) The test site is an open outdoor testbed.

[0160] (2) The temperature fluctuates between 5℃ and 35℃, and the sensor used is a DHT22 temperature sensor.

[0161] (3) The LED display method is the red, green, and blue of the RGB LED.

[0162] (4) The rain detection sensor is an analog output type.

[0163] (5) Rainfall detection is determined as rainfall when the sensor value is 500 or higher, and rainfall is measured based on the analog value of the rainfall detection sensor with a rainfall amount of 0mm to 10mm / h.

[0165] 2) Experimental Procedure

[0166] (1) The LED color is adjusted to indicate the environmental condition at the initial temperature state. At this time, a blue LED is lit for temperatures below 10℃, a green LED is lit for temperatures between 11℃ and 30℃, and a red LED is lit for temperatures above 31℃.

[0167] (2) When the rain detection sensor detects a value of 500 or more, the LED blinks to indicate that rain has occurred.

[0168] (3) When the rainfall is 1.5 mm or more, the orange LED flashes at 2-second intervals, and when the rainfall is 20 mm or more, the red LED flashes at 1-second intervals to indicate that the rainfall severity is high, and when the rainfall detection is 3 mm or more and lasts for 10 seconds, the rain barrier (410) is automatically closed.

[0169] (4) After the rain stops, the barrier opens automatically after 10 minutes, and the LED returns to a color that reflects the original temperature state.

[0171] 3) Experimental Results

[0172] The experimental results according to this embodiment are shown in Table 3 below.

[0173] Rainfall (mm / h) Rainfall sensor value LED color change Whether the rain barrier (210) is operating Reaction time 0 <500 Maintain temperature-based LED Barrier not operating - 1.5 500~600 Orange LED blinking (2-second cycle) Barrier not operating - 3 600~700 Yellow LED flashing Barrier operation starts 3 seconds 5 700~800 Yellow LED continuously flashing (2-second cycle) Complete closure of the barrier 5 seconds 15 800~900 Red LED flashing Complete closure of the barrier 5 seconds 20 >900 Red LED flashing rapidly (1-second cycle) Complete closure of the barrier 5 seconds 0 (Recovery) <500 Temperature-based LED return Open barrier after 10 minutes 10 minutes

[0174] 4) Conclusion

[0175] As a result of the experiment, when the rainfall detection sensor value was less than 500 and the temperature was 10℃ or lower, the blue LED lit up; when the temperature was 11~30℃, the green LED lit up; and when the temperature was 31℃ or higher, the red LED lit up.

[0176] When the rainfall detection sensor value is 500 or higher, the LED color changes, and as the rainfall increases, the blinking cycle becomes shorter.

[0177] If rainfall exceeded 3mm, the barrier automatically activated to protect the waste.

[0178] At this time, the yellow LED blinked, allowing the user to visually confirm that the barrier had started operating.

[0179] In addition, it was confirmed that the barrier automatically opens and the LED color returns to normal after a certain period of time has elapsed since the rain stopped.

[0180] In other words, within the range where rainfall was not detected, the corresponding RGB LEDs lit up according to the temperature criteria, and when rainfall was detected, the corresponding RGB LEDs blinked according to the amount of rainfall detected.

[0181] In addition, it was visually confirmed that the orange LED blinked when the rainfall sensor value was 500 or higher, and the barrier operated at the same time as the LED changed color to yellow and blinked when the rainfall sensor value was 600 or higher.

[0182] Subsequently, it was confirmed that when the rainfall sensor value was 700 or higher, the yellow LED continued to blink at a 2-second interval, when the rainfall sensor value was 800 or higher, the LED changed color to red, and when the rainfall sensor value was 900 or higher, the red LED blinked rapidly at a 1-second interval.

[0183] Finally, it was confirmed that after a certain period of time, when the rainfall sensor value was again 500 or lower, the barrier was opened and the LED changed color based on the temperature and lit up.

[0185] Hereinafter, Examples 2 to 4 are presented to aid in understanding the LED display and rain barrier operation system linked with temperature and rainfall detection sensors according to the present invention. However, the following examples are provided only to facilitate a better understanding of the present invention, and the present invention is not limited to the following examples.

[0195] 2. Example 3

[0196] An LED display and rain barrier operation system linked with temperature and rainfall detection sensors according to the present invention has been applied to an industrial site. When large quantities of waste are stored exposed at factories and industrial sites, this system can be applied to prevent contamination caused by rainfall.

[0201] (4) Block activation time: Automatic closure was implemented when rainfall intensity exceeded 3 mm / h.

[0203] 3. Example 4

[0204] An LED display and rain barrier operation system linked with temperature and rainfall detection sensors according to the present invention has been applied to an industrial site. When this system is applied to agricultural storage facilities and crop protection facilities, rainfall and temperature conditions can be monitored, and the protective barrier can be automatically opened and closed. For example, the system is configured so that when a sensor installed inside a vinyl greenhouse detects rain, the protective barrier is automatically closed to protect the crops. The LED indicator can serve to immediately notify agricultural workers of the current environmental conditions.

[0205] 1) Experimental Conditions and Results

[0206] (1) Temperature range and LED display: Blue LED lit up at 10℃ or lower, green LED lit up at 11℃ to 30℃, and red LED lit up at 31℃ or higher.

[0207] (2) Rainfall detection criteria: When rainfall of 1 mm or more is detected, the LED flashes orange.

[0208] (3) Shield activation speed: The shield was closed within 3 seconds after the shield activation signal was detected.

[0210] Experimental results: Examples 2 to 4 are the results of applying an LED display and rain barrier operating system linked with a temperature and rainfall detection sensor according to the present invention in the field. Compared to Example 1, the LED display module (300) displays a different color depending on whether rainfall is detected, and when rainfall is detected, the barrier operates according to the amount of rainfall detected, and the barrier is locked based on a threshold value of a specific amount of rainfall and wind speed to protect the system.

[0211] That is, based on the experimental results of the open outdoor testbed through Example 1, the experimental results of field application through Examples 2 to 4 were found to be the same.

[0212] Through these results, it was confirmed that the LED display and rain barrier operation system linked with the temperature and rainfall detection sensors of the present invention detects environmental conditions in real time, provides intuitive visual information through the LED display, and effectively performs barrier operation in response to rainfall.

[0214] The technology of the present invention detects changes in the surrounding environment of the roll-off box (100) in real time through the configuration of a temperature sensing sensor, a rainfall sensing sensor, and a wind speed sensing sensor, and controls the LED display module (300) and the barrier driving module (400) through the microcontroller according to the detected value.

[0215] Through the LED display module (300), changes in the environment can be intuitively identified at a location where the user's gaze falls, such as by changing the LED color or flashing. In the event of rain detection, the barrier driving module (400) can be operated in an automated manner to reduce the burden on manpower, and in the event of strong winds, the opening and closing of the barrier can be restricted to increase the durability and stability of the device.

[0216] In addition, by integrating with IoT functions, users can remotely monitor and control the operating status of the barrier in real time, thereby maximizing user convenience.
