[0002] When a car breaks down on the road and cannot move, the hazard warning lights should be kept on, and warning signs should be set up in the direction of oncoming vehicles to expand the warning distance.

[0058] The following is combined with Figure 1-4 This application is described in further detail.

[0059] In one embodiment, if Figure 1 As shown, the present application discloses a portable fast-charging ejection warning roadblock method, which specifically includes the following steps:

[0060] S10: collecting vehicle status data in real time, and automatically triggering a chemical reaction start instruction of the metal container when an emergency event is detected;

[0061] S20: When a chemical reaction start instruction is received, the rupture of the diaphragm in the metal container is activated, the solid reactants and the liquid reactants are mixed, and a chemical reaction occurs to generate gas;

[0062] S30: Inflate a warning triangle based on the generated gas;

[0063] S40: Based on the key environmental data obtained in real time and combined with the preset environment-ejection parameter database, the corresponding adjustment ejection parameters are matched and the inflated warning sign is launched to the target deployment position behind the vehicle.

[0064] In this embodiment, the rapid deployment of warning signs is achieved through intelligent perception and automated control. First, the system collects vehicle status data in real time, accurately identifies emergency events, and automatically triggers the chemical reaction instructions of the metal container. Subsequently, the solid and liquid reactants in the metal container are mixed and quickly generate gas. Finally, based on the real-time environmental data, the preset ejection parameter library is matched and the ejection parameters are dynamically adjusted so that the inflated warning sign is accurately ejected to the target position behind the vehicle. This method significantly reduces the risk of manual operation through full-chain automated control, and the inflation and ejection processes are synergistically optimized to ensure the rapid deployment of warning signs under complex road conditions, effectively improving the safety and timeliness of road emergency response.

[0065] Figure 2 , step S10 includes:

[0066] S101: Modeling standard vehicle state data to generate a vehicle state model;

[0067] S102: Collect vehicle status data of the target vehicle in real time, and extract abnormal features of the vehicle status data based on preset extraction rules:

[0068] S103: The vehicle status data includes dynamic parameters and mechanical parameters;

[0069] S104: The preset extraction rules include mutation rules, association rules, persistence rules, and coupling rules;

[0070] S105: Based on the mutation rule: extracting the instantaneous pressure drop feature from the tire pressure value of the mechanical parameter;

[0071] S106: Based on association rules: extracting steering mismatch features from the steering wheel angle of the dynamic parameter and the yaw angular velocity of the mechanical parameter;

[0072] S107: Based on the persistence rule: extracting the temperature rise out of control feature from the engine compartment temperature of the mechanical parameter;

[0073] S108: Based on the coupling rule: extracting collision-related features from the vehicle speed drop of the dynamic parameter and the airbag triggering state of the mechanical parameter.

[0074] In this embodiment, after constructing a vehicle state model, dynamic and mechanical parameters are collected in real time, and abnormal features are extracted using four types of rules: mutation rules capture instantaneous tire pressure anomalies (such as signs of a blowout); association rules analyze the compatibility of steering operation with vehicle body dynamics (such as the risk of loss of control); continuous rules monitor continuous increases in engine temperature (such as the risk of spontaneous combustion); and coupling rules correlate sudden drops in vehicle speed with the status of safety devices (such as collision determination). This multi-rule collaborative mechanism transcends the limitations of single-threshold alarms, significantly improving the coverage and accuracy of event recognition and reducing the risk of misjudgment.

[0075] Figure 3 , step S10 further includes:

[0076] SB1: Input the abnormal features into the vehicle state model, perform emergency event judgment on the abnormal features based on preset emergency event rules, and output the judgment result;

[0077] SB2: The preset emergency event rules include collision determination rules, tire blowout determination rules, spontaneous combustion determination rules, and loss of control determination rules;

[0078] SB3: The emergency events include collision, tire blowout, spontaneous combustion, and steering loss of control;

[0079] SB4: The collision determination rule: when the instantaneous pressure drop characteristic exceeds a first preset threshold and the collision-related characteristic exceeds a second preset threshold, it is determined to be a collision event;

[0080] SB5: The tire blowout determination rule: when the instantaneous pressure drop characteristic exceeds a second preset threshold, it is determined to be a tire blowout event;

[0081] SB6: The spontaneous combustion determination rule: when the temperature rise out of control characteristic exceeds a fourth preset threshold, it is determined to be a spontaneous combustion event;

[0082] SB7: The out-of-control determination rule: when the steering mismatch characteristic exceeds a sixth preset threshold, it is determined to be a steering out-of-control event;

[0083] SB8: When the judgment result is any emergency event, the chemical reaction start instruction of the metal container is triggered.

[0084] In this embodiment, abnormal features are input into a pre-set emergency event rule base for identification: a collision event requires both a sudden drop in tire pressure and airbag activation; a tire blowout event is triggered solely by a sudden drop in tire pressure; a spontaneous combustion event relies on a sustained temperature increase; and a loss of control event is determined by a steering mismatch. The hierarchical design of the rule base enables refined event classification, ensuring that subsequent processes are triggered only when the feature combination meets the pre-set logic, avoiding ineffective responses.

[0085] Step S20 includes:

[0086] S201: When the diaphragm in the metal container ruptures, start real-time monitoring of the gas generation and flow rate;

[0087] S202: When the generated amount reaches a preset pressure threshold and the flow rate is maintained stably for a preset time period, the inflation is determined to be complete.

[0088] In this embodiment, after the metal container's diaphragm ruptures, the system monitors gas generation and flow stability in real time: A pressure threshold is determined to ensure that inflation intensity meets the specified level (e.g., ≥20 kPa); and flow stability is maintained to verify that the reaction process is controllable (e.g., fluctuations <5%). This dual verification mechanism ensures both efficient and safe inflation, preventing deployment failures caused by gas leaks or insufficient pressure.

[0089] Step S40 includes:

[0090] S401: Real-time collection of key environmental data, including road slope and curvature, wind speed and direction, vehicle current speed, and the position of the target deployment area relative to the vehicle;

[0091] S402: Based on a preset matching algorithm, the key environment data is matched with a preset environment template library to match the preset environment template with the highest similarity;

[0092] S403: Input the preset environment template into the preset environment-ejection parameter database to match the corresponding adjustment ejection parameters;

[0093] S404: The adjustment of ejection parameters includes ejection angle, air pressure intensity and spring compression;

[0094] S405: Based on the corresponding adjusted ejection parameters, the inflated warning sign is launched to the target deployment position behind the vehicle.

[0095] In this embodiment, ejection parameters are dynamically matched based on environmental data: an environmental template library stores ejection parameter combinations for typical scenarios (e.g., curves, strong winds, and ramps); a matching algorithm quickly locks in the optimal parameters through similarity calculations (e.g., cosine similarity > 90%); and ejection execution combines multiple factors such as angle, air pressure, and spring compression to achieve a precise landing point within a range of 50-200 meters. This design enables stable deployment of warning signs even in complex road conditions, with strong adaptability and high energy efficiency.

[0096] The steps after S40 include:

[0097] SH1: When the warning sign touches the ground, a shape transformation instruction is sent to the warning sign based on the real-time collected landing impact force data and road material detection results;

[0098] SH2: When receiving the form conversion command, trigger the bottom support frame to unfold and fix the module.

[0099] In this embodiment, intelligent fixation is activated after the warning sign touches the ground: an electric actuator deploys the tripod, enhancing its anti-tip capability. The fixation module, for example, uses barbed spikes and quick-release glue to create a "mechanical and chemical" anchoring mechanism on asphalt or gravel surfaces. On metal guardrails, an electromagnetic adsorption module dynamically adjusts the adsorption force. On icy and snowy roads, heating melts the ice, allowing the glue to penetrate and adhere. This module ensures the warning sign's rapid stability in diverse environments, significantly improving wind resistance and visibility.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
