[0099] That is, in this alternative embodiment, the natural disaster monitoring sensor is used to monitor natural disaster information in real time (i.e., the occurrence information of natural disasters), and send the natural disaster information to the natural disaster early warning device through communication methods such as satellite communication, Ethernet, or mobile cellular network;

[0100] After the natural disaster early warning device performs identity verification according to the identity information corresponding to the natural disaster monitoring sensor, when it determines that the identity information corresponding to the natural disaster monitoring sensor is legal, it determines that natural disaster early warning information can be issued, and transmits it to the early warning information transmission device within the disaster affected area through methods such as satellite communication, wired Ethernet, and cellular mobile communication.

[0121] Table 4

[0122]

[0123]

[0124] In an alternative embodiment, the target terminal is used to display the natural disaster warning information through a Human Machine Interface (HMI).

The specific content of this natural disaster update information is basically the same as the content included in Table 1.

[0144] After the early warning information transmission device updates the natural disaster early warning information and the disaster shelter information according to the disaster update information, it broadcasts them to the target terminal.

[0145] In an optional embodiment, the early warning information transmission device is further configured to obtain information indicating the end of a natural disaster, and broadcast the disaster early warning cancellation information within the communication coverage of the early warning information transmission device.

[0146] That is, in this optional embodiment, after the natural disaster ends, it is also necessary to broadcast the disaster early warning cancellation information to the target terminal to inform that the natural disaster has ended.

[0147] In an optional embodiment, the target terminal is configured to determine whether the target terminal has left the predicted impact range of the natural disaster according to the natural disaster early warning information and the current position of the target terminal, and display through the HMI whether the target terminal has left the predicted impact range of the natural disaster.

[0148] In this optional embodiment, the target terminal determines whether it has left the disaster impact range based on its own position and the predicted impact range of the natural disaster indicated by the natural disaster early warning information, and notifies the user that it has left the disaster range through a corresponding interface and method.

[0150] The RSU is assigned a unique ID, the installation position parameters are measured and calibrated, and are entered into the natural disaster early warning device;

[0151] The disaster monitoring sensor is assigned a unique ID, the installation position parameters are measured and calibrated. If it is a sensor directly connected to the RSU device, the position parameter information and the ID number information are entered into the RSU device (the same sensor can be connected to multiple RSU devices). If it is a sensor connected to the natural disaster early warning device, the position parameter information and the ID number information are entered into the natural disaster early warning device;

[0154] The natural disaster early warning device collects and maintains information on disaster emergency shelters;

[0155] The natural disaster early warning device receives information intelligence and generates disaster early warning information. The generation methods include:

[0156] (1) The natural disaster early warning device receives the data reported by the disaster monitoring sensors, determines whether a natural disaster has occurred, and generates a natural disaster early warning message;

[0157] (2) The natural disaster early warning device receives the disaster information forwarded by existing natural disaster early warning systems such as the earthquake early warning monitoring system, the meteorological disaster early warning monitoring system, and the fire early warning monitoring system, and generates a natural disaster early warning message;

[0158] (3) Some RSU devices are directly connected to disaster monitoring sensors. After detecting disaster information, the RSU will report the disaster information to the natural disaster early warning device and generate a natural disaster early warning message;

[0159] (4) For the disaster information obtained through other channels, the natural disaster early warning device can generate a natural disaster early warning message after verification and authorization by the administrator;

[0160] After the natural disaster early warning device generates a natural disaster early warning message, it will generate an emergency shelter information according to the disaster type and the saved emergency shelter data;

[0161] The natural disaster early warning device sends the natural disaster early warning message and the shelter information to the RSUs within the affected range according to the scope of the disaster impact. The sending methods include satellite communication, cellular network communication, Internet, dedicated Ethernet, etc.;

The information input methods include satellite communication, cellular network communication, Internet, dedicated Ethernet, etc.;

[0163] After receiving the natural disaster early warning message and the shelter information sent by the natural disaster early warning device, the RSU calculates and generates a target shelter;

[0164] For the RSU devices directly connected to disaster monitoring sensors, they can generate natural disaster early warning messages by themselves. They can broadcast the locally generated natural disaster early warning messages through C-V2X, and at the same time, they will also report and send the natural disaster early warning messages to the natural disaster early warning device. The sending methods include satellite communication, cellular network communication, Internet, dedicated Ethernet, etc.;

[0165] The RSU periodically broadcasts the natural disaster early warning message and the shelter information through C-V2X. Since the RSU is fixedly deployed, only the vehicles / pedestrians / non-motor vehicles driving into the area covered by the RSU deployment will receive the natural disaster early warning message and the shelter information, realizing the accurate sending of messages;

[0166] After the drone or helicopter supporting C-V2X communication reaches the target area, it calculates and generates evacuation instruction information for the current flight area based on the pre-input disaster warning information and evacuation shelter information.

[0167] The unmanned aerial vehicle supporting C-V2X communication broadcasts local natural disaster warning information and evacuation shelter information externally through C-V2X within the flight area. The unmanned aerial vehicle maintains an appropriate flight speed and altitude to ensure the coverage effect of C-V2X messages in the target area.

[0168] After receiving the local natural disaster warning information, the vehicle OBU processes the information in combination with its own location information, generates warning prompt information and warning indication images on the in-vehicle HMI, and simultaneously plays the prompt information through voice. The prompt information can include recommended driving behaviors and driving directions, such as accelerating through or stopping immediately, etc. At the same time, a help button is provided on the HMI interface.

[0169] After receiving the local natural disaster warning message, the P-UE processes the information in combination with its own location information. If there is an in-vehicle HMI, it generates warning prompt information and warning indication images, and simultaneously plays the prompt information through voice. At the same time, a physical help button can be provided. After receiving the warning prompt information, the vehicle occupants can choose whether to seek help according to their own and vehicle conditions. After selecting the help function, the OBU will send a rescue request to the RSU / drone.

[0170] After receiving the local natural disaster warning information, the mobile phone supporting C-V2X processes the information in combination with its own location information, generates warning prompt information and warning indication images on the mobile phone interface, and simultaneously plays the prompt information through voice. The prompt information can include recommended risk avoidance behaviors, and at the same time, a help button is provided on the mobile phone interface.

[0171] After triggering the help function, the vehicle OBU / P-UE / mobile phone will send a help message externally through C-V2X.

[0172] After receiving the help message, the RSU / drone stores the rescue information itself, provides data support for the post-disaster rescue work, facilitates the rescue personnel to understand the vehicle information that needs to be rescued, and after processing the information, it will send the terminal help message to the natural disaster warning device. The sending methods include satellite communication, cellular network communication, Internet, dedicated Ethernet, etc.

[0173] After receiving the help message, the natural disaster warning device notifies the emergency contact of the terminal status according to the disaster status emergency contact pre-registered by the terminal.

[0174] When the vehicle OBU / P-UE / mobile phone is in a normal state, it will periodically send out mobile location information. When it is in a disaster warning state after receiving a disaster warning message, the RSU / unmanned aerial vehicle should record the vehicles passing through its coverage area to provide data support for post-disaster rescue work and facilitate rescue personnel to understand the vehicle information that needs to be rescued.

[0175] After receiving a rescue request, the RSU stores the rescue information itself to provide data support for post-disaster rescue work and facilitate rescue personnel to understand the vehicle information that needs to be rescued. At the same time, it reports this information to the disaster warning information center through satellite communication, cellular network communication, the Internet, dedicated Ethernet, etc.

[0176] After the disaster disappears or has ended, the disaster warning information center or the RSU can send out a warning cancellation message (the message type is also a natural disaster warning information). After receiving it, the vehicle OBU / P-UE / mobile phone OBU notifies the user to display the warning cancellation message through the corresponding vehicle HMI interface and method.

[0177] After the disaster intensity changes, if it affects the classification of the disaster hazard area level, the natural disaster warning device needs to send out a warning update message (the message type is also a natural disaster warning information). After receiving it, the RSU / unmanned aerial vehicle calculates the information, generates updated local disaster warning information and evacuation shelter information, broadcasts the local disaster warning message and evacuation instructions information externally through C-V2X. After receiving it, the vehicle OBU / P-UE / mobile phone notifies the user that the warning information has been updated and displays the warning update message on the vehicle HMI interface, makes new prompts for the passengers and drivers according to the change of the hazard level, and continues to provide a help button on the HMI interface.

[0178] For some natural disasters with mature response plans, if there are evacuation shelters nearby, for vehicles with autonomous driving capabilities, after receiving the local natural disaster warning message and evacuation shelter information warning message, they can automatically match the evacuation shelter and automatically drive to the evacuation shelter.

[0179] After the vehicle OBU / P-UE / mobile phone and other terminals drive out of the disaster area, the terminal determines that it has left the disaster-affected area and notifies the user that it has left the natural disaster-affected area through the corresponding interface and method, and displays a prompt of leaving the disaster-affected area on the HMI interface.

[0180] The present invention can send disaster warning information to moving vehicles and display it in real time on the in-vehicle HMI. Compared with traditional media such as televisions and radios, it has the characteristics of low propagation delay and accurate and direct information. Relying on the fixed coverage range of the RSU in C-V2X technology, accurate warning information transmission can be achieved, and disaster warning information is only sent to vehicles within the geographical range affected by the disaster. It does not rely on 4G / 5G networks and has a large coverage range. C-V2X technology can achieve information transmission under all-weather and all-weather conditions, realizing all-weather disaster warning information transmission; it can be docked with the vehicle's autopilot system to transmit disaster warning information and disaster avoidance driving information to the autopilot system, supporting the autopilot system to make decisions on disaster avoidance driving plans; it can send disaster warning information to bicycles, electric vehicles, and pedestrians; and unmanned aerial vehicles can be used to broadcast and send disaster warning information to areas and sections without cellular mobile network coverage.
