Abstract
Description
Technical Field
[0001] This utility model relates to the field of highway safety warning equipment, specifically a remote safety warning device for highway road operations. Background Technology
[0002] Currently, with the development of intelligent driving technology for new energy vehicles not yet fully autonomous, accidents involving vehicles accidentally entering work sites and causing injuries or fatalities are not uncommon, especially when drivers and passengers are completely off-duty on highways. Coupled with various high-risk driving factors such as fatigued driving, long-distance driving at night, and novice drivers, the safety situation at highway work sites is exceptionally severe and complex. Currently, the only measures available are signs, cones, and audible and visual alarms to warn passing vehicles, which are insufficient to address the issue of emergency evacuation for workers in the event of a hazard. Therefore, it is necessary to design a safety warning device that enables targeted, remote transmission of danger signals to workers to alert them to take emergency evasive action, thereby improving the safety of highway work sites. Utility Model Content

The input terminal of the lithium battery is connected to the output charging pin of the charge / discharge management module. The power supply pin of the audio alarm module is connected to the IO pin of the main controller (controlling the audio alarm module to start or stop playing via a level signal). The audio mode selection pin of the audio alarm module is connected to another IO pin of the main controller. The input terminal of the boost circuit is connected to the audio signal output terminal of the audio alarm module. The output terminal of the boost circuit is electrically connected to the voltage of the frequency-converted square wave signal output by the buzzer to enhance the alarm sound of the buzzer.

This effectively improves the safety of road work. Furthermore, the device boasts advantages such as fast signal transmission, targeted person-to-person alerts, minimal susceptibility to external interference, and high portability, making it highly valuable for practical applications.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Please see Figure 1A remote safety warning device for highway road-related operations comprises a wireless remote control transmitter module 12, a wireless receiver module 13, a button circuit 10, an LED warning circuit 11, a main controller 14, a lithium battery 15, a charge / discharge management module 16, an audio alarm module 17, a boost circuit 18, and a buzzer 10. The wireless remote control transmitter module 12 is a Hummingbird-Ling-T5A, and the wireless receiver module 13 is a Micro-R2-433. The wireless remote control transmitter module 12 and the wireless receiver module 13 should be used in pairs, and the wireless receiver module 13 is Micro-R2-433. Pin 2 of circuit 3, the DAT data output, is connected to the IO pin of the main controller 14, which is responsible for collecting and analyzing the received wireless signals. The button circuit 10 is a standard microswitch, with one end connected to the main power supply negative terminal and the other end connected to the IO pin of the main controller 14, responsible for turning the entire device on and off and switching functions. The LED warning circuit 11 consists of a set of red lights and a set of blue lights connected in series, and each connected to one of the two IO pins of the main controller 14, responsible for lighting the lights. The lithium battery 15 provides power to the entire device and is connected to the charging and discharging diode. The output charging pin of the charging module 16 is connected; the charge / discharge management circuit 16, model TC4056A, has both constant current and constant voltage charging models, and can convert a traditional 5V charger to charge a 3.7V lithium battery. Its 5th pin, BAT, should be connected to the positive terminal of the lithium battery; the audio alarm module 17, model S9561, selects the sound type by configuring the high and low levels of the third pin F1 and the seventh pin F2. Connecting the third pin F1 to the main controller 14IO pin and leaving the seventh pin F2 floating allows for the playback of two sounds by controlling the high and low levels of F1 to differentiate between the two. It is divided into emergency and non-emergency situations; its power supply port VDD is connected to the IO of the main controller 14, and the main controller 14 outputs high and low levels to control the sound to be turned on and off. At the same time, its seventh pin audio signal output pin outputs a frequency-converted square wave signal, which requires an external transistor (such as 9013) to drive the speaker; the boost circuit 18 is a three-pin boost inductor, and its input terminal is connected to the seventh pin audio signal output pin of the audio alarm module 17. It is used to amplify the voltage of the frequency-converted square wave signal output by the audio alarm module 17 to improve the alarm sound of the piezoelectric ceramic buzzer 19.
[0020] The following section provides a detailed description of the workflow and status.
[0021] In the entire device, the button circuit serves as the main switch and function toggles. Pressing it once activates the wireless alarm function, typically used during the day.
[0022] Press the second button to simultaneously activate the wireless alarm function and the LED flashing warning function, which is commonly used at night; press the third button to turn off the device.
[0023] For the LED flashing warning function, the controller determines the number of button presses and directly controls the high and low levels of the output pins, alternately controlling the LED warning circuit 11 to flash.
[0024] For the wireless alarm function, the wireless remote control transmitter module 12 has multiple buttons, each representing a different situation, such as the alert signal button and the emergency avoidance signal button. When the lookout presses one of the buttons, the wireless remote control transmitter module 12 will transmit a signal. This signal is received by the receiver module 13 and transmitted to the main controller 14 for parsing and analysis. Once the decoding is successful, the microcontroller controls the output of a high level to activate the audio alarm module 17 and play the corresponding alarm sound. Since the output driving capability of the audio alarm module 17 is limited, the voltage is boosted by the boost circuit 18, ultimately driving the piezoelectric ceramic buzzer 19 to sound the alarm.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
