Description

Technical Field

[0001] This invention relates to a photovoltaic self-powered smart construction warning cone system. Background Technology

[0002] In scenarios such as road construction, traffic accident handling, and temporary traffic control, traffic cones (also known as road cones or traffic cones) are the most commonly used warning and isolation facilities. Existing ordinary traffic cones mainly rely on reflective film pasted on their surface for passive reflection, and at night or in rainy or foggy weather, they rely on the reflection of vehicle headlights to serve as a warning. However, this traditional solution has the following prominent technical drawbacks: First, the warning capabilities at night and in inclement weather are severely inadequate: In rainy or foggy weather, on curves, at the top of hills, and other areas with poor visibility, drivers often only notice the reflections of the cones when they are very close, leaving extremely little reaction time. Statistics show that approximately 35% of traffic accidents in construction zones are directly related to the warning cones being discovered too late.

[0003] Secondly, traffic cones cannot actively trigger alarms after being hit: When traffic cones are knocked down, run over, or displaced by vehicles, on-site construction workers often cannot be notified immediately. Following vehicles can then enter the unmarked danger zone, easily leading to secondary or even chain-reaction rear-end collisions. Existing traffic cones completely lack any active sensing or communication capabilities.

[0004] Third, construction information cannot be synchronized to navigation maps in real time: information such as the start and end locations of construction areas and road occupancy needs to be manually reported to traffic management departments or map platforms, resulting in significant delays. Drivers may see information from hours or even days ago on navigation software, posing a high risk of being misled.

[0005] Fourth, the reliance on manual inspection and counting results in low management efficiency: after construction is completed, the cones need to be manually collected one by one, the quantity needs to be counted, and the damage needs to be checked, which is time-consuming and labor-intensive; the cones are often lost or left on site, causing property damage and safety hazards.

[0006] Fifth, if electronic warning lights are added, there is a power supply bottleneck: a few high-end cones have tried to add battery-powered LED warning lights, but the batteries need to be replaced frequently (usually every 3-7 days), and the maintenance cost is extremely high in remote construction scenarios; the drag cable solution is not suitable for temporary and highly mobile construction scenarios.

[0007] Therefore, there is an urgent need for an intelligent construction warning cone system that is self-powered, provides active warnings, triggers collision alarms, and is linked to the cloud. Summary of the Invention

[0008] To address the aforementioned problems in existing technologies, this invention provides a photovoltaic self-powered smart construction warning cone system, which solves the problems of weak warning capabilities, lack of alarm when hit, lack of information linkage, low management efficiency, and difficulty in power supply of existing construction warning cones.

The active warning module is used to emit multi-mode light and sound warning signals, including a high-brightness LED light strip surrounding the upper part of the middle cone of the cone body, and a buzzer / voice unit embedded in the lower part of the middle cone of the cone body. The communication and linkage module is integrated and installed inside the sealed and waterproof base at the bottom of the cone body. It is used to complete equipment data transmission, linkage control between cones, and information interaction with third-party platforms. The controller module is integrated and installed inside the sealed and waterproof base at the bottom of the cone body. It is used to receive data from each module, run the event judgment algorithm, control the active warning module to perform corresponding actions, and coordinate the communication and linkage module to report data and send linkage commands. The remote management and operation platform is used to realize remote control and operation management of the cone throughout its entire lifecycle.

[0010] Preferably, the photovoltaic power supply module specifically includes: a flexible photovoltaic thin-film module, an energy storage unit, and an energy management circuit, wherein, Flexible photovoltaic thin-film modules, using weather-resistant flexible copper indium gallium selenide or perovskite photovoltaic materials, are used to convert light energy into electrical energy; The energy storage unit uses a wide-temperature lithium iron phosphate battery or a hybrid supercapacitor, which is electrically connected to a flexible photovoltaic thin-film module to store electrical energy. The energy management circuit, used to connect the flexible photovoltaic thin-film module and the energy storage unit, includes an MPPT maximum power point tracking charge controller, an overcharge and over-discharge protection circuit, and a low-power sleep / wake-up management circuit.

[0011] Preferably, the multi-source sensing module specifically includes: an attitude detection unit, a localization unit, and an environment sensing unit; wherein, The attitude detection unit integrates a tilt sensor and a three-axis accelerometer to detect changes in the tilt angle and acceleration of the cone in real time. It has a built-in MCU that runs an impact detection algorithm and incorporates gyroscope data fusion. When the change in synthetic acceleration exceeds a preset threshold and the impact duration is greater than 50ms, it is determined to be an impact event; If the tilt angle remains greater than 45° for more than 2 seconds, it is considered a tipping event; The positioning unit integrates a GPS / BeiDou dual-mode positioning chip to obtain the real-time location information of the cones; The environmental sensing unit integrates an ambient light sensor and a temperature and humidity sensor to determine day / night cycles and monitor the operating environment of the equipment.

[0012] Preferably, the active warning module specifically includes: a high-brightness LED light strip, a buzzer / voice unit, and a warning mode adaptive unit, wherein, The high-brightness LED light strip uses high-brightness red / yellow LEDs to achieve 360° high visibility warning with no blind spots through multi-mode active light emission; Buzzer / voice unit, integrating a small waterproof speaker, is used to automatically play preset voice warnings when an abnormal approach of a vehicle is detected; The warning mode adaptive unit is used to automatically adjust the warning mode according to time, weather, and event level. The warning mode includes, but is not limited to, a default slow flashing yellow light at night, and an automatic switch to fast red flashing light with maximum brightness after being hit.

[0013] Preferably, in the buzzer / voice unit, a vehicle's abnormal approach is detected by radar or vibration characteristics, triggering a high-frequency flashing and voice warning in advance.

[0014] Preferably, the communication and linkage module specifically includes: a wide-area communication unit, a self-organizing network communication unit, and a cloud platform linkage interface, wherein, The wide-area communication unit integrates a 4G Cat.1 or NB-IoT communication module for regularly reporting device heartbeat and location data in outdoor scenarios without Wi-Fi, and immediately wakes up to report when an event is triggered. The self-organizing network communication unit integrates a LoRa or Bluetooth Mesh chip, which is used to broadcast linkage instructions to other cones within a range of 50-200 meters after a collision event is detected by the cone, thus creating a chain warning effect; The cloud platform linkage interface is used to connect with third-party platforms and automatically push information such as the location of the construction section, the lanes occupied, and the estimated duration of the occupancy.

The historical trajectory playback unit is used to query the position movement trajectory of a specific cone within any time period; The multi-level alarm push unit supports multiple alarm methods, including SMS, APP push, and Webhook, and allows setting different recipients based on the alarm level.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a high-brightness LED light strip with 360° multi-mode active illumination and a buzzer for voice warning, enabling drivers to detect construction areas from 300 meters away. This solves the technical defect of traditional reflective cones that "passively rely on light reflection." Furthermore, through an adaptive warning mode unit, the warning mode automatically switches according to day / night, weather, and event level (such as slow flashing yellow light at night and fast red flashing after a collision), significantly improving the warning effect in poor visibility areas such as rain, fog, and curves. This invention enables interlocking warnings between traffic cones. After an accident occurs, traffic cones within a 50-200 meter radius simultaneously trigger emergency warnings, allowing subsequent vehicles to be aware of the danger an average of 2 kilometers in advance. The invention also uses radar / vibration features to identify abnormal vehicle approach and triggers high-frequency flashing and voice warnings in advance, thus shortening the warning response time for dangerous behaviors such as fatigued driving and speeding. This invention enables proactive alarms for abnormal states such as impact, tipping, low battery, and unauthorized movement, avoiding the risk of omissions during manual inspections.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1 As shown, a photovoltaic self-powered smart construction warning cone system includes: a cone body 1, a photovoltaic power supply module 2, a multi-source sensing module 3, an active warning module 4, a communication and linkage module 5, a controller module 6, and a remote management and operation and maintenance platform 7.

[0020] The cone body 1 is made of a highly elastic polymer material and includes a top conical surface, a middle conical body, and a bottom sealed waterproof base.

[0021] The photovoltaic power supply module 2 is used to provide a continuous and stable power supply for the entire system module. It includes a flexible photovoltaic thin film component 21 that is attached to the top conical surface and the bottom sealed waterproof base surface of the cone body 1, an energy storage unit 22 installed inside the bottom sealed waterproof base of the cone body, and an energy management circuit 23 that connects the flexible photovoltaic thin film component 21 and the energy storage unit 22.

[0022] like Figure 2 As shown, the photovoltaic power supply module 2 specifically includes: a flexible photovoltaic thin-film module 21, an energy storage unit 22, and an energy management circuit 23, wherein, The flexible photovoltaic thin-film module 21 uses weather-resistant flexible copper indium gallium selenide or perovskite photovoltaic materials, which can adapt to the shape of a conical curved surface and can still generate electricity under low light conditions (cloudy days, dawn, dusk) to convert light energy into electrical energy. The surface of the flexible photovoltaic thin-film module 21 is covered with a scratch-resistant and self-cleaning coating to adapt to harsh outdoor environments. The energy storage unit 22 uses a wide-temperature lithium iron phosphate battery or a hybrid supercapacitor, with an operating temperature range of -30℃ to 70℃ and a capacity of 2000mAh to 5000mAh, which can meet the battery life requirements for more than 5 consecutive days of cloudy and rainy weather. It is electrically connected to the flexible photovoltaic thin film module for storing electrical energy. Energy management circuit 23, used to connect the flexible photovoltaic thin-film module and the energy storage unit, includes an MPPT maximum power point tracking charge controller, an overcharge and over-discharge protection circuit, and a low-power sleep / wake-up management circuit; wherein, The MPPT (Maximum Power Point Tracking) charging controller is used to monitor the output voltage and current of flexible photovoltaic thin-film modules in real time and dynamically adjust the load impedance to ensure that the photovoltaic modules always operate at the maximum power point with the highest power generation efficiency. The overcharge and over-discharge protection circuit is used to monitor the battery voltage, current, and temperature parameters of the energy storage unit in real time. When the battery voltage exceeds the preset overcharge threshold (e.g., 3.65V / cell) or falls below the over-discharge threshold (e.g., 2.8V / cell), the charging or discharging circuit is automatically cut off. It also has a temperature protection function, which is triggered when the battery temperature is higher than 60℃ or lower than -20℃, effectively preventing battery damage and extending the service life of the energy storage unit. The low-power sleep / wake-up management circuit is used to automatically cut off the power supply to non-essential modules (such as the active warning module 4 and the communication and linkage module 5) when the system is under low load or during periods of no light, so that the system enters a low-power sleep state (total power consumption ≤10μA); when a signal of light restoration, vibration trigger, or timed wake-up is detected, the system is quickly started to enter the working mode, ensuring both battery life and emergency response speed.

[0023] That is, after the flexible photovoltaic thin film module 21 converts light energy into electrical energy, the charging efficiency is optimized by the MPPT charging controller of the energy management circuit 23 and stored in the energy storage unit 22; the electrical energy output by the energy storage unit 22 provides stable power to all power-consuming modules of the system after passing through the over-charge and over-discharge protection circuit; the low-power sleep wake-up management circuit controls the energy storage unit 23 to enter sleep state during non-working periods to reduce power consumption.

[0024] The multi-source sensing module 3 is integrated and installed in the inner cavity of the cone body 1 in the middle section. It is used to collect the cone tilt angle, acceleration, and real-time position information in real time, and to complete the day and night judgment and equipment working environment monitoring.

[0025] like Figure 3 As shown, the multi-source sensing module 3 specifically includes: an attitude detection unit 31, a localization unit 32, and an environment sensing unit 33; wherein, The attitude detection unit 31 integrates a tilt sensor and a three-axis accelerometer to detect changes in the tilt angle and acceleration of the cone in real time. It has a built-in MCU that runs an impact detection algorithm and incorporates gyroscope data fusion. When the change in synthetic acceleration exceeds a preset threshold and the impact duration is greater than 50ms, it is determined to be an impact event; If the tilt angle remains greater than 45° for more than 2 seconds, it is considered a tipping event; Positioning unit 32 integrates a GPS / BeiDou dual-mode positioning chip to obtain the real-time location information of the cone, supports AGPS assisted positioning, cold start positioning time <30 seconds, hot start <2 seconds, and positioning accuracy better than 2 meters; The environmental sensing unit 33 integrates an ambient light sensor and a temperature and humidity sensor for determining day and night conditions and monitoring the operating environment of the equipment.

[0026] That is, the data collected by the tilt sensor, triaxial accelerometer and gyroscope of the attitude detection unit 31 are fused and calculated by the built-in MCU to achieve accurate identification of impact / tipping events; the position and environmental data collected by the positioning unit 32 and the environmental perception unit 33, together with the processing results of the attitude detection unit 31, are transmitted to the controller module 6 through the data bus.

[0027] The active warning module 4 is used to emit multi-mode light and sound warning signals, including a high-brightness LED light strip 41 surrounding the upper part of the middle cone of the cone body 1, and a buzzer / voice unit 42 embedded in the lower part of the middle cone of the cone body 1.

[0028] like Figure 4 As shown, the active warning module 4 specifically includes: a high-brightness LED light strip 41, a buzzer / voice unit 42, and a warning mode adaptive unit 43, wherein, The high-brightness LED light strip 41 uses high-brightness red / yellow LEDs to achieve 360° high visibility warning with no blind spots through multi-mode active light emission. The buzzer / voice unit 42 integrates a small waterproof speaker to automatically play a preset voice warning when an abnormal approach of a vehicle is detected. The abnormal approach of a vehicle is detected by radar or vibration characteristics, and high-frequency flashing and voice warning are triggered in advance. The warning mode adaptive unit 43 is used to automatically adjust the warning mode according to time (day / night), weather (obtained via network), and event level (whether it has been hit). The warning mode includes, but is not limited to, a default slow flashing yellow light at night, and an automatic switch to fast red flashing light with maximum brightness after being hit.

[0029] That is, the warning mode adaptive unit 43 receives the instructions from the controller module 6 and the environmental data from the multi-source perception module 3, and automatically adjusts the light emission mode (color, flashing frequency, brightness) of the high-brightness LED light strip 41; the buzzer / voice unit 42 identifies abnormal vehicle approach through radar or vibration sensor, triggers high-frequency flashing and voice warning, and feeds back the warning information to the controller module 6.

[0030] The communication and linkage module 5 is integrated and installed inside the bottom sealed waterproof base of the cone body 1. It is used to complete equipment data transmission, inter-cone linkage control and information interaction with third-party platforms.

[0031] like Figure 5 As shown, the communication and linkage module 5 specifically includes: a wide-area communication unit 51, a self-organizing network communication unit 52, and a cloud platform linkage interface 53, wherein, Wide area communication unit 51 integrates 4G Cat.1 or NB-IoT communication module, used for regular reporting of device heartbeat and location data in outdoor scenarios without Wi-Fi, and immediately wakes up to report when an event is triggered; The self-organizing network communication unit 52 integrates a LoRa or Bluetooth Mesh chip to broadcast a linkage command to other cones within a 50-200 meter range after a cone detects a collision event, thus creating a chain reaction warning effect. Specifically, when a cone detects a collision event, it broadcasts a linkage command to other cones within a 50-200 meter range via the self-organizing network. Upon receiving the command, adjacent cones immediately upgrade their warning mode to "emergency mode" (fast red flashing + double brightness), thus creating a chain reaction warning effect. The cloud platform linkage interface 53 is used to connect with third-party platforms (such as Gaode Map's "Smart Cone" and Baidu Map's "Eagle Eye") to automatically push information on the location of the construction section, the lanes occupied, and the estimated duration of the occupancy.

[0032] Specifically, the wide area communication unit 51 is responsible for routine data interaction with the remote management and operation and maintenance platform 7 (reporting heartbeat and location data on a regular basis) and emergency reporting after an event is triggered; the self-organizing network communication unit 52 broadcasts linkage instructions to surrounding cones after detecting a collision event; the cloud platform linkage interface 53 realizes data docking with the third-party navigation platform and pushes construction information; all three units interact with the controller module 6 through the data communication interface.

[0033] The controller module 6 is integrated and installed inside the sealed and waterproof base at the bottom of the cone body 1. It is used to receive data from each module, run the event judgment algorithm, control the active warning module 4 to perform corresponding actions, and coordinate the communication and linkage module 5 to report data and send linkage commands.

[0034] The remote management and operation platform 7 is used to realize remote control and operation management of the cone throughout its entire life cycle.

[0035] like Figure 6 As shown, the remote management and maintenance platform 7 specifically includes: a web-based / APP-based facility group management unit 71, a real-time status dashboard unit 72, a historical trajectory playback unit 73, and a multi-level alarm push unit 74. The web / APP-based facility group management unit 71 is used by construction personnel to create facility groups (such as "G2 Expressway K108+300 to K108+800, occupying the first lane") and define the construction scope, and automatically number all cones within the deployment scope and generate electronic fences. The real-time status dashboard unit 72 is used to display the real-time position, battery percentage, attitude status (upright / tilted), communication status, and last reporting time of each cone. The historical trajectory playback unit 73 is used to query the position movement trajectory of a specific cone within any time period. The multi-level alarm push unit 74 supports multiple alarm methods, including SMS, APP push, and Webhook, and allows setting different recipients according to the alarm level.

[0036] That is, the construction scope and cone number information created by the facility group management unit 71 on the web page / APP are synchronized to the real-time status dashboard unit 72 and the historical trajectory playback unit 73; the real-time status dashboard unit 72 displays the real-time operation data of each cone; the historical trajectory playback unit 73 queries the position movement trajectory of the cone; the multi-level alarm push unit 74 pushes alarm information to different recipients according to the alarm level; all units interact with the communication and linkage module 5 through the network interface.

[0037] Workflow of the photovoltaic self-powered smart construction warning cone system: Step S1, System initialization and startup Cone placement: Construction workers place cones in the construction area. The pressure sensor at the bottom of cone body 1 detects the pressure change and triggers the system to start. Automatic start-up: Energy storage unit 22 supplies power to multi-source sensing module 3, communication and linkage module 5, and controller module 6 through energy management circuit; Hardware self-test: The controller module 6 sequentially detects the working status of the photovoltaic power supply module 2, multi-source sensing module 3, active warning module 4, and communication and linkage module 5. If a fault is found, it will be reported to the remote management and operation and maintenance platform 7 through the communication and linkage module 5. Network registration: Wide area communication unit 51 searches for and connects to the operator's network, registers the device ID, and establishes a communication link with the remote management and maintenance platform 7; Time synchronization: Standard time is obtained through positioning unit 32 to synchronize the internal clock of the system; Entering normal mode: The system initialization is complete, and the active warning module 4 enters the default warning mode (such as a constant red light during the day and a slow flashing yellow light at night).

[0038] Step S2, Normal Operation Phase Photovoltaic charging: The flexible photovoltaic thin film module 21 converts light energy into electrical energy, optimizes the charging efficiency through the MPPT charging controller of the energy management circuit 23, and stores it in the energy storage unit 22; the overcharge and over-discharge protection circuit monitors the status of the energy storage unit 22 in real time, and automatically cuts off the charging or discharging circuit when the battery voltage exceeds the overcharge threshold or falls below the over-discharge threshold. Data collection: The attitude detection unit 31 collects the tilt angle, acceleration, and gyroscope data of the cone in real time, and performs fusion calculations through the built-in MCU; Positioning unit 32 collects the real-time position information of the cone every 5 minutes; The environmental sensing unit 33 collects ambient light intensity, temperature, and humidity data in real time; Status determination: Controller module 6 runs an event determination algorithm to determine whether the cone is in a normal state based on the collected data; Data reporting: Wide area communication unit 51 reports device heartbeat, location, power, attitude, and environmental data to remote management and maintenance platform 7 every 30 minutes; Mode adjustment: The warning mode adaptive unit 43 automatically adjusts the light emission mode of the high-brightness LED strip 41 according to the ambient light intensity (such as constant light during the day and slow flashing at night), and adjusts the charging and discharging strategy of the energy storage unit 22 according to the temperature data.

[0039] Step S3, Event Trigger Response Event detection: When the change in synthetic acceleration exceeds a preset threshold and the impact duration is greater than 50ms, it is determined to be an impact event; If the tilt angle remains greater than 45° for more than 2 seconds, it is considered a tipping event; When radar or vibration sensors detect an abnormally close vehicle, it is considered a warning event; Local alert: Controller module 6 immediately controls active alert module 4 to switch to emergency alert mode (such as red flashing, continuous buzzer alarm, and voice message "Construction ahead, please give way"). Data reporting: Wide area communication unit 51 is immediately woken up and reports the event type, occurrence time, cone position, and status data to remote management and operation and maintenance platform 7; Cone linkage: The self-organizing network communication unit 52 broadcasts linkage instructions to other cones within a range of 50-200 meters, and the surrounding cones simultaneously switch to emergency warning mode; Platform Alarms: After receiving event data, the remote management and maintenance platform 7 sends SMS, APP push or Webhook alarms to construction personnel and project management personnel through the multi-level alarm push unit; Incident Handling: After receiving the alarm, the construction personnel went to the site to handle the incident. After the incident was handled, the cone status was reset through the remote management and maintenance platform 7, and the system returned to normal operation.

[0040] Step S4, Remote Operation and Maintenance Management Facility Group Management: Construction personnel can create facility groups and define the construction scope through the facility group management unit 71 on the web / APP. The system will automatically number all cones within the deployment area and generate an electronic fence. Real-time monitoring: The real-time status dashboard unit 72 displays the real-time position, battery percentage, attitude status, communication status, and last reporting time of each cone. Track query: The historical track playback unit 73 can be used to query the position movement trajectory of a specific cone within any time period; Alarm Handling: After receiving alarm information, administrators can view the event details through the remote management and maintenance platform 7 and arrange personnel to handle it; Firmware upgrade: The remote management and maintenance platform 7 can push firmware upgrade packages to the cone. After receiving the upgrade package, the controller module 6 automatically completes the system upgrade and maintains the normal operation of the warning function during the upgrade process.

A photovoltaic self-powered intelligent construction warning cone system according to claim 1, characterized in that, The remote management and maintenance platform specifically includes: a web-based / APP-based facility group management unit, a real-time status dashboard unit, a historical trajectory playback unit, and a multi-level alarm push unit. The web-based / app-based facility group management unit is used by construction personnel to create facility groups and define the construction scope, and automatically number all cones within the deployment area and generate electronic fences. The real-time status dashboard unit is used to display the real-time position, battery percentage, attitude status, communication status, and last reporting time of each cone. The historical trajectory playback unit is used to query the position movement trajectory of a specific cone within any time period; The multi-level alarm push unit supports multiple alarm methods, including SMS, APP push, and Webhook, and allows setting different recipients based on the alarm level.
