DETAILED DESCRIPTION

[0022] The embodiments described below are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See Figures 1 to 3 This embodiment provides a solar alarm device, comprising a support column 10, a mounting base 20 disposed at the bottom of the support column 10, a solar energy supply mechanism 30, a warning mechanism, a radar sensor 40, and a controller. Specifically, the solar alarm device provided by this application can be installed by drilling a mounting hole at the mounting location with an impact drill, then aligning the M10 bolt hole 21 on the mounting base 20 with the mounting hole at the mounting location, and then screwing in the M10 bolt. After installation, the solar alarm device converts solar energy into electrical energy through the solar alarm device, providing a continuous power supply for the device. The radar sensor 40 equipped with the device can monitor the surrounding environment in real time. Once an abnormality is detected, it immediately issues a warning in various ways through the warning mechanism, thereby reminding the driver or other traffic participants to pay attention to safety. The controller determines whether to activate the warning mechanism based on a preset logical judgment (which only involves simple logical judgments such as if and elif, which will not be elaborated here), and reminds the driver or other traffic participants to pay attention to safety through various alarm methods.

[0024] See Figure 3Specifically, in this application, the solar energy supply mechanism 30 includes a solar photovoltaic panel 31, a battery pack 32, and a conversion module 33. The solar photovoltaic panel 31 is rotatably mounted on the top of the support column 10. The battery and the conversion module 33 are disposed inside the support column 10. The conversion module 33 includes a solar controller 34, a power conversion unit 35, a power control unit 36, and an output interface 37. The solar photovoltaic panel 31 and the battery pack 32 are respectively connected to the power conversion unit 35 via the solar controller 34, and the power conversion unit 35 is connected to the output interface 37 via the power control unit 36. It should be noted that the solar photovoltaic panel 31 is designed to be rotatable and mounted on the top of the support column 10 so that its angle can be adjusted according to the position of the sun to ensure maximum solar energy reception. When sunlight shines on the solar photovoltaic panel 31, the solar photovoltaic panel 31 converts light energy into DC electrical energy, which first enters the conversion module 33 through the solar controller 34. The solar controller 34 is responsible for monitoring the output voltage and current of the photovoltaic panel to ensure that it operates within a safe and efficient range. At the same time, the solar controller 34 is also responsible for controlling the charging process between the photovoltaic panel and the battery pack 32 to prevent overcharging or over-discharging. The power conversion unit 35 in the conversion module 33 is responsible for performing the necessary conversions on the DC power generated by the solar photovoltaic panel 31 to meet the needs of different devices and loads. The power control unit 36 ​​controls the operating state of the power conversion unit 35 according to the actual needs and current status of the system to ensure stable output of electricity. The conversion module 33 ultimately provides electrical energy to other parts of the entire solar alarm device, such as the warning mechanism, radar sensor 40, and controller, through the output interface 37. The output interface 37 adopts a standardized design, which facilitates connection and communication with other devices or components through wire plugging. At night or on cloudy days, when there is insufficient solar energy, the battery pack 32 will play its role. Battery pack 32 is connected to power conversion unit 35 via solar controller 34. When the power generated by solar photovoltaic panel 31 is insufficient to meet system requirements, battery pack 32 releases its stored energy to provide power to the entire system. In this way, solar energy supply mechanism 30 ensures that the solar alarm system receives a stable and reliable power supply at any time and in any weather conditions, thereby ensuring its normal operation and efficient operation.

[0025] See Figure 1 as well as Figure 2Specifically, the warning mechanism includes a warning light 51, a font display module 52 and a sound source alarm 53. The warning light 51, the font display module 52 and the sound source alarm 53 are all arranged on the outer surface of the support column 10 and are electrically connected to the output interface 37; the radar sensor 40 is arranged on the support column 10 and is electrically connected to the output interface 37; the controller is arranged in the support column 10, and is connected to the solar energy supply mechanism 30, the warning mechanism and the radar sensor 40, for receiving the sensing signal of the radar sensor 40 and controlling the operation of the warning mechanism.

[0026] See Figure 2 It should be noted that the radar sensor 40 has a sensing range set at 1 to 9 meters. Once a person, vehicle, or other moving object enters this detection range, the radar sensor 40 immediately detects the presence of the moving object and quickly transmits this information to the controller. The controller is responsible for receiving and processing the signals from the radar sensor 40. Once the controller receives an intrusion signal (urgently approaching a person, vehicle, etc.) from the sensor, it immediately initiates a pre-set response procedure. First, the controller sends a command to the sound source alarm 53, causing it to broadcast a clear voice alert, warning the intruder that they have entered the warning area. Simultaneously, the controller also sends a command to the warning light 51, causing it to flash to provide a visual warning. At night, when pedestrians cross this dangerous area, the controller activates the illuminated font display module 52, allowing the font on the device to clearly display the warning message, providing additional safety for pedestrians. Font options include "Stop, Look, Confirm, and Pass," "Beware," and "Do Not Pass."

[0027] Preferably, the battery pack 32 is connected to a charging port, which is connected to a municipal power supply. By connecting to a municipal power supply for charging, the battery pack 32 can still provide a stable power supply in the event of insufficient solar energy or continuous rainy weather, thereby improving the reliability of the entire system.

[0028] Preferably, the font display module 52 includes a predetermined number of LED light strips and transparent fonts arranged on the surface of one side of the support column 10, and the LED light strips are fitted on the back of the transparent fonts. It should be noted that transparent fonts are provided on the surface of one side of the support column 10. These fonts are made of highly transparent materials, such as acrylic plates or glass. The design of the transparent fonts allows the light of the LED light strips to pass through the fonts, forming a bright display effect. The LED light strips are fitted on the back of the transparent fonts, ensuring that light can be evenly and directly irradiated onto the transparent fonts, so that the fonts can be clearly seen at night or in dark places. At the same time, the LED light strips are connected to the output interface 37 and the controller through wires. They receive instructions from the controller to work. When a warning message needs to be displayed, the controller will send a signal to the LED light strips to light up and illuminate the transparent fonts.

[0029] To further enhance the visibility and safety of the solar alarm device at night or in low-light conditions, this design incorporates a reflective layer 61 on the other three sides of the support column 10. This layer 61 is made of a highly reflective material, such as reflective film or paint. These materials have excellent reflective properties and can produce strong reflections in dim light, making the device more visible and enhancing the warning effect.

[0030] Preferably, the radar sensor 40 includes a processing unit and a sensing unit. The sensing unit is configured to transmit a millimeter-wave spectrum and receive the reflected millimeter-wave spectrum. The processing unit demodulates the millimeter-wave spectrum and outputs the demodulated millimeter-wave spectrum to the controller. Specifically, due to its short wavelength and high frequency characteristics, the millimeter-wave spectrum can accurately penetrate air and obstacles, effectively detecting moving objects. When a person, vehicle, or other moving object enters the detection range, the sensing unit quickly captures the millimeter-wave spectrum reflected from these objects. The processing unit then receives the reflected spectrum data and, using its built-in existing demodulation technology, extracts the information from the signal and processes it. The controller then receives this processed information. Therefore, the radar sensor 40 not only improves the alarm device's detection accuracy for moving objects, but also ensures the device's stability and reliability in complex environments, providing users with more efficient and reliable security.

[0031] Preferably, a circle of LED light strips 62 is provided in a ring on the top side of the support column 10, and the LED light strips 62 are connected to the solar energy supply mechanism 30. The LED light strips 62 are arranged in a ring to ensure that bright light can be emitted in multiple directions, thereby attracting the attention of surrounding pedestrians and vehicles.

[0032] Preferably, a mounting opening is defined on one side of the support column 10, and a mounting door 63 is provided on the mounting opening. This design allows users or maintenance personnel to access key components within the support column 10, such as the battery pack 32, conversion module 33, or other electronic devices, by simply opening the mounting door 63, without disassembling the entire device. This design significantly improves the maintainability of the device, allowing for faster and more efficient repairs, component replacements, or configuration adjustments.

[0033] Preferably, a photosensitive switch is also provided, and the LED light bar 62 is electrically connected to the photosensitive switch. A photosensitive switch is a device that automatically switches a circuit on and off based on the ambient light intensity. When the ambient light is sufficient, the photosensitive switch senses sufficient light and automatically closes the circuit connected to the LED light bar 62, turning off the LED light bar 62 to save energy and extend its life. In low ambient light conditions, particularly at night or in low-light conditions, the photosensitive switch senses the lack of light and automatically opens the circuit connected to the LED light bar 62, illuminating the LED light bar 62 and providing a continuous warning effect.

[0034] Preferably, a device on / off button is provided on the top of the support column 10, and the device on / off button is connected to the controller. The device on / off button allows the user to easily control the operating status of the entire device. By simply pressing or switching the button, the user can activate or deactivate the alarm device, achieving quick and convenient operation.

[0035] Preferably, the controller is a PLC controller. In this embodiment, the PLC controller (Programmable Logic Controller) has a built-in known program.

[0036] The present invention provides a solar alarm device comprising a solar energy supply mechanism 30, an alarm mechanism, a radar sensor 40, and a controller, achieving functions such as energy conservation and environmental protection, efficient warning, and intelligent control. Specifically, the solar alarm device utilizes a solar photovoltaic panel 31 to convert solar energy into electrical energy, providing continuous power supply for the device, achieving the use of green energy, reducing the cost of use, and being suitable for remote areas or places with unstable power supply; the alarm mechanism can quickly issue an alarm signal when the radar sensor 40 senses an abnormal situation through various means such as a warning light 51, a font display module 52, and a sound source alarm 53, effectively reminding traffic participants to pay attention to safety; at the same time, the controller intelligently receives the signal from the radar sensor 40 and controls the operation of the alarm mechanism according to the signal, thereby improving the automation level and response speed of the device. Therefore, the solar alarm device is not only energy-saving and environmentally friendly, but also has the characteristics of efficient warning and flexible installation, providing a strong guarantee for traffic safety.

[0037] The above disclosures are merely some preferred embodiments of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
