Description

Technical Field

[0001] This utility model belongs to the field of warning and prompting devices, specifically, it relates to an automatic audible and visual early warning and prompting device for dangerous sections of highways. Background Technology

[0002] Modern highways often have numerous dangerous sections due to inherent factors such as terrain and topography, including sharp bends, steep slopes, sections near cliffs, water, and tunnels. These sections are prone to traffic accidents due to limited visibility or complex road conditions. To reduce safety risks, various warning signs are usually installed during highway construction. However, these signs are passive warnings and cannot effectively eliminate the safety hazards posed by dangerous road sections in a timely manner.

[0003] To further improve driving safety, some highway management departments have installed audible and visual warning devices on top of existing signs to proactively alert drivers to dangerous road sections. However, existing audible and visual warning devices still have the following shortcomings: First, these devices generally only issue warnings when a vehicle enters a dangerous section, lacking early warning capabilities, often resulting in drivers not reacting in time and failing to take effective measures. Second, most existing devices are either always on or always off, failing to automatically control operation based on the presence of vehicles on the road, causing them to continue working even when no vehicles are passing, which not only consumes a lot of energy but may also cause light pollution and noise pollution.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies and provide an automatic audible and visual early warning device for dangerous road sections. This device is designed to improve road safety, particularly for dangerous road sections with limited visibility or complex conditions, such as sharp bends, steep slopes, sections near cliffs, water, and tunnels. It provides early warnings to inform drivers that the road ahead is dangerous, giving them sufficient time to react and take effective measures, thereby reducing the occurrence of traffic accidents.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An automatic audible and visual early warning device for dangerous sections of highways includes: an audible and visual warning unit, a front-end sensor, and an audible and visual alarm host. The audible and visual alarm host includes a power supply module, a signal receiving module, a signal processing module, and a signal output module.

[0008] A front sensor is set in front of the dangerous road section to detect vehicles entering. The signal processing module receives the detection signal and performs logical judgment. When it is determined that a vehicle has entered the detection range, a control signal is output.

[0009] The output of the front sensor is connected to a data cable, which is electrically connected to the signal interface of the signal receiving module.

[0010] Signal connections between the signal receiving module and the signal processing module; signal connections between the signal processing module and the signal output module;

[0011] The output terminal of the power module is electrically connected to a first power line and is electrically connected to the power interface of the front sensor through the first power line.

[0012] When a vehicle enters the monitoring range of the front sensor, the main unit of the audible and visual alarm activates the audible and visual prompt unit to issue a warning; if no vehicle is detected passing through after a preset time, the main unit of the audible and visual alarm automatically enters sleep mode.

[0013] Optional, the audio-visual cue unit includes:

[0014] A flashlight, with a second power cable connected to its power interface, electrically connected to the signal output module, emits a flashing warning light when the control signal is received; a horn, with an audio cable connected to its interface, electrically connected to the signal output module, emits an audible or voice prompt when the control signal is received.

[0028] The system includes an audible and visual prompt unit, a front sensor 1, and an audible and visual alarm host 6. The audible and visual alarm host 6 includes a power supply module, a signal receiving module, a signal processing module, and a signal output module.

[0029] The front sensor 1 is set in front of the dangerous road section to detect vehicles entering. The signal processing module receives the detection signal and performs logical judgment. When it is determined that a vehicle has entered the detection range, a control signal is output. The power module also supplies power to the signal receiving module, the signal processing module, and the signal output module.

[0030] The output end of the front sensor 1 is connected to a data line 3, and the data line 3 is electrically connected to the signal interface of the signal receiving module. The signal processing module is a CPU chip in the prior art.

[0031] Signal connections between the signal receiving module and the signal processing module; signal connections between the signal processing module and the signal output module;

[0032] The output terminal of the power module is electrically connected to the first power line 2 and is electrically connected to the power interface of the front sensor 1 through the first power line 2; the power module can be powered by external AC power or solar photovoltaic power.

[0033] When a vehicle enters the monitoring range of the front sensor 1, the audible and visual alarm host 6 activates the audible and visual prompt unit to issue a warning; when no vehicle is detected passing through after a preset time, the audible and visual alarm host 6 automatically enters sleep mode.

[0034] In this embodiment, the audio-visual prompt unit includes:

[0035] A flashlight 4 has a power interface connected to a second power line 7, which is electrically connected to the signal output module. Upon receiving the control signal, the flashlight emits a flashing warning light. A warning horn 5 has an audio line 8 connected to it, which is electrically connected to the signal output module. Upon receiving the control signal, the horn emits an audible or voice prompt. This dual warning system of light and sound provides drivers with intuitive information in various environments, improving the warning effect and reliability. Simultaneously, the audible and visual warning unit is electrically connected to the signal output module, ensuring the stability of the control signal transmission and enabling rapid response, thus enhancing the practicality and safety of the device.

[0036] In this embodiment, the front sensor 1 is a photoelectric sensor.

[0037] In this embodiment, the distance between the installation location of the front sensor 1 and the dangerous road section is 100 to 200 meters. This distance setting fully considers the driver's reaction time and the vehicle's braking distance, ensuring that the driver has sufficient time to take measures such as deceleration, braking, or avoidance after receiving the warning, thereby effectively reducing the accident rate of dangerous road sections.

[0038] In this embodiment, the flashlight 4 uses a dual-color LED energy-saving light source.

[0039] Working Principle: When a vehicle enters a dangerous section of the highway approximately 100-200 meters before its arrival, a photoelectric sensor installed outside the highway guardrail detects the vehicle signal and outputs it to the main unit of the audible and visual warning device. Upon receiving the signal, the main unit immediately activates the audible and visual warning unit, causing the LED warning light on the top of the main unit to flash and simultaneously activating the voice prompt function. The voice prompt content can be pre-recorded and stored in the main unit according to the specific scenario. The device remains operational while vehicles continuously pass by; if no vehicle is detected for more than 2 minutes, the main unit automatically enters sleep mode. During sleep mode, energy consumption is effectively reduced, and light pollution and noise interference are avoided. When the next vehicle enters the sensor's detection range, the main unit is awakened again and the audible and visual warning unit is activated, and this cycle repeats continuously.
