Description

Technical Field

[0001] This invention relates to the field of highway safety warning technology, specifically a segmented flashing warning light system triggered at any point and a dynamic indexing method. Background Technology

[0002] Highways, tunnels, icy roads due to cold weather, rain, fog, and nighttime driving are all scenarios prone to causing vehicle accidents. After an accident occurs, it's difficult for onlookers to immediately warn others, hindering the effective transmission of warning signals. Traditional methods, such as shouting and waving arms, are largely ineffective. Placing warning triangles takes 5-8 minutes, during which time more than a dozen vehicles may have passed. Furthermore, injured occupants in some accidents may be unable to disembark, making it difficult to quickly prevent chain-reaction collisions. In fact, the fatalities in accidents are often not those in the initial collision vehicle, which may only suffer vehicle damage and minor injuries. The real danger lies with speeding vehicles failing to brake in time, relentlessly colliding with parked vehicles and pedestrians, causing serious injuries and fatalities. Numerous chain-reaction accidents occur annually, some involving 30-40 vehicles, resulting in numerous injuries and fatalities and economic losses in the hundreds of millions each year. Without effective emergency prevention measures, subsequent chain-reaction accidents involving even more vehicles and fatalities may occur.

[0003] Existing industrial safety warning light systems offer limited fault warning methods and content. While highly targeted, they only inform personnel in specific areas of any malfunctions. These systems are limited to industrial production quality alarms, equipment malfunction alarms, and building fire safety warnings, and have not yet been applied to highways. The core reason is that current technology fails to address the possibility of triggering warnings at any point during an accident, lacking corresponding infrastructure solutions for arbitrary triggering. Furthermore, there is no clear and effective method to reliably activate the warning lights after a traffic accident, failing to meet the emergency warning needs of highways and providing insufficient safety assurance for vehicles traveling on highways. Therefore, there is an urgent need to develop an arbitrary-point-triggered segmented flashing warning light system and a dynamic indexing method to overcome the shortcomings in current practical applications. Summary of the Invention

[0004] The purpose of this invention is to provide a segmented flashing warning light system triggered at any point and a dynamic indexing method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A segmented flashing warning light system triggered at any point adopts a layered distributed architecture, which includes a central monitoring layer, a core control layer, a regional control layer and a field device layer from top to bottom, with communication connections between each layer; The field equipment layer includes several warning lights and arbitrary point triggering devices installed along the road; The core control layer assigns a unified number to all warning lights according to their physical installation order. It can respond to the trigger signal of the arbitrary point triggering device, index a preset number of adjacent warning lights behind the trigger point, and control the indexed warning lights to flash at different flashing frequencies in segments according to their distance from the trigger point. The core control layer can also process multiple trigger point signals and support reset operations after fault clearance.

[0006] As a further aspect of the present invention: the central monitoring layer includes industrial-grade computing equipment and supporting host computer software, used to realize global status display, alarm management, historical data recording, remote control and parameter setting functions; The parameters include the number of warning lights that illuminate after being triggered and the flashing frequency.

[0007] As a further aspect of the present invention: the core control layer includes a main controller, which is used to run core logic, manage the virtual mapping table of warning lights, and interact with the regional control layer and the central monitoring layer. When the number of warning lights reaches a preset scale, the main controller adopts redundant deployment and achieves seamless switching through a dual-machine hot standby mechanism.

[0008] As a further aspect of the present invention: the regional control layer is a distributed intelligent node, used to receive instructions from the core control layer, control the operation of specific warning lights, and collect the fault status of the warning lights and report it to the core control layer.

[0009] As a further aspect of the present invention: the warning lights in the field device layer are configured with intelligent drivers, the intelligent drivers support status feedback and preset communication protocols, the communication protocols being selected from DALI-2, KNX, DMX512 or RS485Modbus RTU.

[0010] As a further aspect of the present invention: the arbitrary point triggering device includes a trigger baffle and / or a manual trigger switch; The trigger baffle is installed along the roadbed and can be triggered by a vehicle collision; the manual trigger switch is used for quick manual triggering.

[0011] A segmented flashing dynamic indexing method triggered at any point, based on the aforementioned segmented flashing warning light system triggered at any point, includes the following steps: (1) The core control layer assigns a unified number to all warning lights in the system according to their physical installation sequence and establishes a correspondence between the numbers and their physical locations; (2) After any trigger point is triggered, the core control layer responds to the trigger signal and indexes a preset number of adjacent warning lights behind the trigger point; (3) The core control layer controls the indexed warning lights to be segmented according to their distance from the trigger point, and each segment of the warning light flashes at a different flashing frequency; (4) If a new trigger point exists, the core control layer adjusts the index and flashing state of the warning light according to the positional relationship between the new trigger point and the existing warning range; (5) After the fault is cleared, all warning lights are restored to normal status by resetting.

[0012] As a further aspect of the present invention: in step (3), the indexed warning light is divided into at least three segments according to the distance from the trigger point from near to far, and the flashing frequency of each segment decreases sequentially.

[0013] As a further aspect of the present invention: in step (4), if the new trigger point is within the existing warning range, the index range and flashing state of the warning light are updated based on the new trigger point; If the new trigger point is outside the existing warning range, a new warning light index range will be added. The system supports multiple independent warning light groups existing simultaneously.

[0014] As a further aspect of the present invention: in step (5), the reset operation includes remote reset command triggering, on-site manual reset triggering, or automatic reset after a preset timeout period.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The present invention provides a segmented flashing warning light system and dynamic indexing method that can trigger a number of warning lights behind the trigger point to light up and flash immediately when a vehicle accident occurs, by triggering the trigger baffle of the vehicle colliding with the roadbed or by manually triggering the trigger switch (which can be completed in just a few seconds, completely replacing the 5-8 minute operation of placing the warning triangle). This quickly transmits the accident signal to the drivers of vehicles behind. Drivers can visually judge the approximate distance between themselves and the accident site by the flashing frequency of the warning lights, which gradually increases from far to near (2 times / second, 4 times / second, 6 times / second), thereby creating a sense of urgency and consciously controlling the vehicle speed and maintaining a safe distance, giving the driver 3 to 5 seconds of braking reaction time. This system can effectively suppress more vehicles from being involved in accidents, avoid major chain-reaction car crashes, transform the risk of potentially major car crashes into ordinary rear-end collisions, or even directly prevent accidents from occurring, minimize casualties and huge economic losses, and keep the number of vehicles involved in chain-reaction car crashes to no more than 3 as much as possible, thereby reducing the probability of casualties. Meanwhile, the system supports multi-trigger point processing. When a warning light is triggered again within the range where it is already lit, the warning range will be updated with the latest trigger point. If the new trigger point is not within the existing warning range, a new warning segment will be added. This system can adapt to scenarios where multiple accidents occur at the same time or the accident range expands. The system can also be integrated into navigation apps, allowing drivers on the road to know the status of the warning lights in advance, further improving the foresight of the warnings. After the fault is cleared, the warning lights can be restored to normal status through system settings, ensuring the rapid restoration of traffic order on the road. It is suitable for important road sections such as highways, tunnels, overpasses, and areas with frequent accidents and rainy or foggy weather, and can effectively reduce secondary injuries from traffic accidents.

[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] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0020] Please see Figure 1 To address the technical problem that vehicles cannot immediately warn oncoming traffic after an accident in scenarios such as highways, tunnels, icy roads, rainy / foggy weather, and nighttime driving, which can easily lead to major chain-reaction accidents, causing numerous casualties and huge economic losses, this embodiment discloses a segmented flashing warning light system triggered at any point and a dynamic indexing method. Through the combination of hardware architecture deployment and software logic control, it achieves a rapid, accurate, and graded warning effect after an accident, providing drivers of following vehicles with sufficient braking reaction time and effectively suppressing the occurrence of chain-reaction accidents.

[0021] I. System Overall Architecture This system adopts a layered distributed architecture design, consisting of a central monitoring layer, a core control layer, a regional control layer, and a field device layer from top to bottom. Each layer works collaboratively to ensure the stable and efficient operation of the system, as detailed below: (1) Central monitoring layer (SCADA / HMI) This level serves as the global management center of the system, and the hardware consists of a server or industrial computer 2 and a computer monitor 1. The server or industrial computer 2 is a standard rack-mounted device, installed in the cabinet and power distribution box 3 or on the control room console. The computer monitor 1 is connected to the server or industrial computer 2 via VGA / DP / HDMI cables. The cabinet and power distribution box 3 are used to install and protect controllers, switches and other equipment. The industrial computer or server 2 should meet the requirements of industrial-grade environmental adaptability and have the characteristics of electromagnetic interference resistance and wide temperature operating range. The software uses WinCC, Intouch, Ignition, or C# / Python self-developed host computer software. The software must be correctly configured with the communication driver (such as Siemens S7 driver, EtherNet / IP driver, etc.) of the core control layer PLC, and the correct IP address, device model and data tag must be set. For network connection, it is connected to the factory backbone network through an industrial Ethernet switch, and finally connected to the main electrical control cabinet in the cabinet and distribution box 3. The network cable is usually shielded Cat5e or Cat6 cable, and fiber optic cable is required for long distances. Its core functions include global status display, alarm management, historical data recording, remote manual control and parameter setting.

[0022] The host computer software displays the working status of the warning lights 4 across the entire road section in real time (on / off status, flashing frequency, and fault information, etc.), facilitating remote monitoring and intervention by management personnel. Meanwhile, historical data records can be used for accident tracing and system optimization. The parameter setting function supports adjusting parameters such as the number of lights that illuminate and the flashing frequency after the warning lights 4 are triggered according to different road section scenarios (such as tunnels, long downhill slopes, and accident-prone areas), improving the system's adaptability.

[0023] (2) Core control layer (main controller) The hardware uses high-performance PLCs (such as Siemens S7-1500R / H, Beckhoff CX20xx) or industrial PCs with real-time systems, which are installed as core modules on the DIN rails of the main electrical control cabinet in the cabinet and distribution box 3. When the system scale reaches more than 10,000 warning lights 4, redundant PLCs are deployed. The redundant PLCs achieve seamless switching through a dual-machine hot standby mechanism to ensure uninterrupted system operation.

[0024] In terms of network connectivity, the upstream is connected to the control room network through its Ethernet port, and the downstream is connected to the fieldbus to the regional control cabinets through its real-time Ethernet port (such as Profinet or EtherCAT port).

[0025] The core responsibilities of this level include: running core fault diagnosis and cascading logic, managing virtual mapping tables for more than 10,000 warning lights, high-speed data exchange with each area controller, and handling communication with the host computer.

[0026] The high-performance PLC has fast data processing and logic operation capabilities, and can instantly generate instructions such as calculating the index range of warning lights 4 and allocating flashing frequencies after an accident is triggered; the deployment of redundant PLCs avoids system paralysis caused by single point of failure, ensuring the continuity of warning functions in emergency situations, and the management of virtual mapping tables enables precise addressing and status control of a large number of warning lights 4.

[0027] (3) Regional control layer (distributed intelligent nodes) The hardware uses intelligent gateways / slave PLCs that support real-time Ethernet (such as Siemens ET200SPIM155-5PNHF, Beckhoff EK1100+EL series modules, or gateways from brands like Honghu and Beryllium), which are installed on the DIN rails of the field control cabinets; each area controller manages a certain number of warning lights 4, thus decomposing the control tasks of the large-scale warning lights 4. Network topology typically uses a daisy chain configuration to reduce cabling. Terminal resistors are required at both ends of the network. Cables should be laid along cable trays or in conduits and kept away from power cables to prevent interference. A stable 24VDC industrial power supply is required.

[0028] Its functions include receiving instruction packets from the main controller, controlling specific lamps through the lower-level lighting bus protocol, collecting the fault status of the lamps and packaging and reporting it to the main controller.

[0029] The distributed deployment reduces the load on the core control layer, improves the system's response speed and scalability, and facilitates system expansion when subsequent road sections are extended. The fault status collection and reporting function enables real-time monitoring of warning light 4, allowing managers to promptly detect and repair faulty lights, ensuring the normal operation of the system.

[0030] (4) Field equipment layer (lighting fixtures and drivers) Warning light 4 requires a built-in or external intelligent driver. The intelligent driver should have a communication interface compatible with the bus protocol to ensure the accuracy of command reception and status feedback. Physical installation should be carried out according to equipment requirements, using bolts, brackets, etc. to fix it in the designated position.

[0031] In terms of electrical and signal connections, the power cord is connected to the circuit breaker or relay output in the area control cabinet. If the driver supports real-time Ethernet (such as Profinet), it is directly connected as a node on the network. If it does not support it, the dimming / frequency adjustment is controlled by hard-wiring (such as 0-10V, 4-20mA, PWM signal) through the digital / analog output module of the distributed I / O station. At this time, the communication protocol is determined by the protocol between the I / O station and the main PLC.

[0032] Communication protocol options include: Profinet / EtherCAT (high performance, good determinism, suitable for lighting scenarios requiring precise synchronization and high-speed control), EtherNet / IP (good integration with the Rockwell ecosystem), DALI / DMX512 (traditional dedicated lighting protocol, in modern architectures, it is usually connected to the main control network through a gateway (such as a DALI to Profinet gateway) to achieve centralized control). DALI-2 (international standard for lighting control, each driver has an independent short address (64 per bus) and group address, supporting status feedback (including luminaire failure)) can be selected according to actual needs. Alternatively, KNX (building automation standard, suitable for complex integration), DMX512 (stage lighting standard, extremely fast response, requires additional wiring for fault detection) or proprietary bus protocols (such as RS485 Modbus RTU, lowest cost) can be selected.

[0033] The adoption of standardized communication protocols such as DALI-2 ensures interoperability between warning lights 4 and drivers from different brands, reducing system construction and maintenance costs. The configuration of the intelligent driver enables precise control of the on / off state and flashing frequency of the warning lights 4, while the status feedback function provides data support for system fault monitoring, ensuring the reliable implementation of the warning function.

[0034] II. Specific Implementation of the Dynamic Indexing Method The following are the specific steps to implement tiered alerts triggered at any point using software logic control: (1) Warning light number 4 configuration In the PLC of the core control layer, all warning lights 4 connected to the system are uniformly numbered according to the physical installation order, with a numbering range of 0 to 9999 (i.e., 0, 1, 2...10000). The number of warning lights 4 can be flexibly adjusted according to the length of the road section and the requirements, and supports an extended sorting of more than 10,000.

[0035] The unified numbering establishes a correspondence between the virtual address and physical location of warning light 4, providing a foundation for accurate indexing after triggering at any point, and ensuring that the system can quickly locate the trigger point and the range of warning light 4 that needs to be lit.

[0036] (2) Arbitrary point triggering and index range determination Let the warning light 4 at any trigger point be numbered "i". When trigger point i is triggered (the trigger signal comes from the trigger baffle 5 where the vehicle collides with the roadbed or from the manual operation of the trigger switch 6), the system automatically indexes 300 consecutive warning lights 4 with numbers (i-1, i-2, ..., i-300) to light up. The starting position of the index range is calculated using max(0, i-300) to achieve boundary protection, preventing the index number from being less than 0, and ensuring that the index range remains valid when the trigger point is close to the start of the road segment. The number of warning lights 4 that light up can be flexibly set according to the on-site needs such as the vehicle speed and road conditions of the road segment (e.g., adjusted to 200, 400, etc.).

[0037] Upon triggering, 300 (or a custom number) warning lights will illuminate instantly, providing "first-time" warning. Compared to the traditional placement of warning triangles (which takes 5-8 minutes), this significantly shortens the warning response time, giving drivers of vehicles behind valuable braking reaction time and effectively preventing multiple vehicles from entering the accident area in a short period of time.

[0038] (3) Segmented flashing frequency control The 300 warning lights 4 that light up after being triggered are divided into three groups of 100 each, according to their numbers: the first group (numbered i-1 to i-100) closest to the trigger point i has a flashing frequency of 6 times / second; the second group (numbered i-101 to i-200) in the middle has a flashing frequency of 4 times / second; and the third group (numbered i-201 to i-300) furthest from the trigger point i has a flashing frequency of 2 times / second. If the trigger point is close to the start of the road segment and the number of warning lights 4 that light up is less than 300, then the lights are grouped proportionally according to the actual number and the corresponding flashing frequencies are assigned.

[0039] By designing a flashing frequency that decreases from near to far, drivers of vehicles approaching from behind can intuitively judge their distance from the accident site based on the flashing speed of warning light 4. The faster the flashing frequency, the closer they are to the accident site, thus creating a sense of urgency from slow to fast, prompting drivers to actively control their speed and maintain a safe distance, avoiding blind driving that could lead to a secondary collision.

[0040] (4) Multi-trigger point processing logic When a segment of 300 warning lights 4 is already lit, if any one of the warning lights 4 within that range is triggered again (i.e., the new trigger point is within the index range of the currently lit warning lights 4), the system will use the latest trigger point as the new "i" and re-update the lit and flashing states of the subsequent 300 warning lights 4. If the new trigger point is not within the index range of any currently lit warning lights 4, the system will re-index another segment of 300 warning lights 4 to be lit, forming a state where two (or more) segments of warning lights 4 are lit at the same time. The system can support a maximum of 10 independent groups of warning lights 4 existing simultaneously.

[0041] The multi-trigger point processing logic adapts to scenarios where multiple incidents occur simultaneously or the scope of the incident expands, ensuring that each incident receives an accurate warning and avoiding safety hazards caused by insufficient coverage of a single warning, thus further improving the system's adaptability to complex incident scenarios.

[0042] (5) Fault recovery mechanism The system is configured with a global reset signal, Reset_All. After the accident is handled and the fault is cleared, the management personnel can issue a reset command through the central monitoring computer monitor 1, the operating server, or the industrial computer 2, or trigger a reset through a manual reset device on site. After receiving the reset signal, the system clears all active warning light groups, and all warning lights 4 return to their normal off state. At the same time, the system can set an independent timeout for each group of warning lights 4. After the timeout, the warning status of that group will be automatically cleared. The timeout can be set to 30 minutes, 60 minutes, etc., depending on factors such as road traffic flow and accident handling efficiency.

[0043] The fault recovery mechanism ensures that the system can quickly return to normal after the accident is resolved, avoiding the waste of resources or misleading subsequent vehicles caused by the warning light 4 remaining on for a long time. The automatic timeout reset function ensures the rapid restoration of traffic order on the road section when the management personnel fail to manually reset it in time.

[0044] III. System Installation and Layout To ensure the implementation of the arbitrary point triggering function and the intuitiveness of the warning effect, the system's on-site installation layout is as follows: (1) Warning light module Warning lights 4 are installed on the roadbed on both sides of the highway, with a 10-meter installation distance between each warning light 4. The installation height is adjusted according to the condition of the guardrails on both sides of the highway, ranging from 0.4 to 1 meter, to ensure that drivers of vehicles can clearly see the status of the warning lights 4. The main line 7 (power line and communication line) connecting the warning lights 4 needs to be buried inside the roadbed. The laying of the main line 7 must comply with industrial wiring standards and be properly treated for moisture-proof, crush-proof, and corrosion-proof. A wiring port extends from the main line 7 at each fixed position of the warning lights 4 to facilitate the installation and maintenance of the warning lights 4. The power line of the warning lights 4 is connected to the output of the circuit breaker or relay in the area control cabinet. The control signal line is connected according to whether the driver supports real-time Ethernet (if supported, it is directly connected to the network; if not supported, it is controlled by hard-wiring through the digital / analog output module of the distributed IO station).

[0045] (2) Triggering the linkage module A trigger baffle 5 is installed between every two adjacent warning lights 4 (spaced 10 meters apart). The trigger baffle 5 is assembled from two 5-meter-long baffles or four 2.5-meter-long baffles. The trigger baffle 5 is installed using a spring-loaded reset type (the combined spring force is set to about 30 kg) or a partially destructible reset type. The trigger switch 6 is installed at both ends below the trigger baffle 5. The trigger baffle 5 is connected to the system circuit through the trigger switch 6. When a vehicle collides with the trigger baffle 5, causing the trigger baffle 5 to be pressed downward, the corresponding points at both ends of the trigger baffle 5 press the trigger switch 6, activating the warning light 4 triggering process. The width of the trigger baffle 5 is 120-200 mm, and the installation height is about 0.35 meters from the road surface, ensuring that the accident vehicle can quickly and effectively contact the trigger baffle 5 to trigger the trigger switch 6.

[0046] The arrangement of trigger baffles at 10-meter intervals achieves full coverage of the roadbed on both sides of the highway, ensuring that the warning system can be triggered when a vehicle collides at any location. This completely solves the problem of limited trigger points in traditional warning methods and improves the system's trigger reliability.

[0047] (3) System integration and navigation linkage The entire warning light system is integrated into mainstream navigation systems via an app. The app interacts with the central monitoring server to obtain the real-time status information of the warning lights and synchronizes it to the navigation map. Drivers traveling on this section of road can know the status of the warning lights ahead in advance through the navigation app, further improving the foresight of the warnings.

[0048] Example: Taking a vehicle accident on a section of a highway as an example, the workflow and effects of this system are as follows: 1. The vehicle loses control and collides with the trigger baffles 5 on both sides of the roadbed. The trigger baffles 5 squeeze the trigger switch 6, and the warning light 4 number i corresponding to the trigger point is identified by the system. 2. The core control layer PLC instantly calculates the index range, and 300 warning lights 4 numbered i-1 to i-300 immediately light up. Among them, warning lights 4 from i-1 to i-100 flash 6 times / second, warning lights 4 from i-101 to i-200 flash 4 times / second, and warning lights 4 from i-201 to i-300 flash 2 times / second. 3. Drivers of vehicles approaching from behind can quickly judge their distance from the accident site by observing the flashing status of warning light 4. The increasing flashing frequency prompts drivers to slow down quickly and maintain a safe distance to avoid entering the accident area. 4. If the accident leads to a secondary collision, the new collision point will trigger the corresponding trigger baffle 5 and trigger switch 6. The system will update the index range based on the new trigger point to ensure that subsequent vehicles can receive the latest warning information. 5. After the accident is handled, the management personnel issue a reset command through the central monitoring computer monitor 1 to the operating server or industrial computer 2. All warning lights 4 are turned off, the navigation APP updates the warning information synchronously, and traffic on the road section returns to normal.

[0049] Through the above application process, this system achieves a rapid warning response within 10 seconds after an accident occurs. Compared with traditional warning methods, it provides drivers of vehicles behind with 3 to 5 seconds of braking reaction time, which can control the number of vehicles involved in a chain-reaction accident to within 3, and most of them are ordinary rear-end collisions, effectively reducing casualties and economic losses, and achieving the core objective of curbing the occurrence of major chain-reaction accidents.

[0050] It should be noted that, in this invention, although the specification describes the embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
