[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0037] The core technology of the intelligent roof halo warning system disclosed in this invention is to use sensors such as laser radar and cameras to monitor and identify the vehicle's surrounding environment in real time, and use communication technology to connect with other electronic equipment in the vehicle to realize information transmission and interaction.
[0038] The following is combined with Figure 1-3 The present invention is described.
[0039] See attached Figure 1 and 2 An intelligent roof halo warning system includes a lower body 9 fixed to the roof and a lifting base 8. The lower body 9 is in the shape of a ring. The front camera module 5, the front laser radar 4 and the light sensor 11 are installed on the side of the lower body 9 facing the front of the vehicle; the rear camera module 13 and the rear laser radar 12 are installed on the side of the lower body 9 facing the rear of the vehicle. The lifting base 8 is arranged on the inner periphery of the lower body 9, and the lower body 9 is equipped with an MCU processing module 14, a power module 15 and a communication module 16. The top of the lifting base 8 is fixedly installed with an upper shell 1, and the upper shell 1 is coaxially arranged with the lower body 9.
[0040] The front laser radar 4 and rear laser radar 12 use a scanning laser radar with a scanning angle range of 180 degrees. The front laser radar 4 and rear laser radar 12 form a 360-degree omnidirectional scanning laser system with a maximum detection range of 200 meters.
[0041] The camera used by the front camera module 5 and the rear camera module 13 is a dedicated image sensor that can obtain image information around the vehicle and perform data analysis according to needs after deep learning.
[0042] See attached Figure 1 and 2 The outer circumference of the upper shell 1 is mounted with a warning light module 10. Several warning light modules 10 are arranged circumferentially around the axis of the upper shell 1. A visual sensor module 2 is installed on the outer circumference of the upper shell 1, facing the front of the vehicle. A light display module 17 is installed near the top of the upper shell 1. An environmental sensor module 6 is installed on the top of the upper shell 1. The light display module 17 includes a left LED synchronous light strip 3 and a right LED synchronous light strip 7. The left LED synchronous light strip 3 is located on the left side of the upper shell 1, and the right LED synchronous light strip 3 is located on the right side of the upper shell 1.
[0043] Among them, the left LED synchronous light strip 3 and the right LED synchronous light strip 7 constitute the halo warning system of this technical solution, and the halo warning system is synchronized with the status of the vehicle's brake and turn lights.
[0044] The environmental sensor module 6 is a device that converts physical quantities such as temperature, humidity, gas concentration, and light intensity of the measured object into electrical signals through electromagnetic induction. It can transmit the position and status information of the measured object to the host computer through wireless transmission, and realize real-time monitoring of the environment and early warning of various dangerous conditions through the light display module 1.
[0045] The present invention discloses an intelligent roof halo warning method, which specifically includes:
[0046] 1. When a vehicle is in motion, if the rear vehicle has poor or obstructed vision, it cannot sense changes in the vehicle's driving status through the vehicle's braking or steering, and cannot make timely and effective judgments on traffic conditions. The halo warning system synchronizes with the vehicle's brake and turn signal status to provide high-level driving signals to the rear vehicle, thus avoiding traffic accidents.
[0047] 2. If it is inconvenient for the occupants to get out of the vehicle, the system will automatically identify the surrounding environment and issue a warning signal. For example, in an outdoor camping scenario, the system can identify wild animals and other people or objects that may pose a danger, and then the system can issue a danger warning signal to the occupants;
[0048] 3. When people move around the vehicle, the system will issue an early warning within a certain range around the vehicle. The system uses sensing devices such as cameras and radars to identify potential danger signals and transmit them to the vehicle, causing the vehicle to sound the horn and the roof halo to flash synchronously to remind people to return to the vehicle.
[0049] The present invention discloses an intelligent roof halo warning system, which specifically includes two modes:
[0050] S1: When the vehicle is driving, the system is in driving mode;
[0051] In driving mode, the upper shell 1 is located inside the lower body 9, and sensor modules such as the front camera module 5 and the front laser radar 4, the rear camera module 13 and the rear laser radar 12 scan the surrounding environment.
[0052] In driving mode, the present invention synchronizes the flashing of the halo warning system's lights with the status of the vehicle's brake and turn lights. The vehicle's brake and turn light signals are transmitted to the LIN bus, and then the roof halo control module is used to receive and parse these signals to control the halo warning system of this technical solution to flash accordingly, ensuring real-time synchronization of the light flashing with the vehicle's light status and providing accurate driving information.
[0053] See attached Figure 3 , complete the following steps to connect to the vehicle LIN bus:
[0054] S101, LIN bus interface module
[0055] The LIN bus interface module is installed on the roof of the vehicle and is used to receive vehicle data such as the vehicle's braking and steering status, and transmit this vehicle data to the LIN bus;
[0056] S102, roof halo control module
[0057] The roof halo control module is installed on the roof and is used to receive vehicle signals such as brake and steering status transmitted by the LIN bus. The roof halo control module is connected to the LIN bus;
[0058] S103, Signal Analysis and Processing
[0059] After receiving vehicle signals such as the braking and steering status transmitted by the LIN bus, the roof halo control module analyzes and processes the signals and controls the lighting status of the roof halo warning system based on the vehicle signals such as the braking and steering status.
[0060] S104, light flashing control
[0061] According to the vehicle's brake and turn signals, the LED lights in the roof halo warning system are controlled to flash accordingly to simulate the status of the vehicle's brake and turn signals;
[0062] S105, Real-time Synchronization
[0063] Ensure that the halo warning system is synchronized with the status of the vehicle's brakes and turn signals to provide accurate driving information to the following vehicles.
[0064] S2: When the vehicle is turned off, the system is in sentry mode;
[0065] In sentry mode, the lifting base 8 drives the upper shell 1 to rise, and the upper shell 1 exceeds the top of the lower body 9, and sensors such as the visual sensor module 2, the environmental sensor module 6 and the light sensor 11 scan the surrounding environment.
[0066] In sentry mode, the technology uses sensors such as lidar and cameras to scan and identify the environment around the vehicle, analyze and identify potential danger signals in the vehicle's surroundings, and assess the degree of danger of the vehicle's surroundings; the identified data is then transmitted to other relevant electronic equipment in the vehicle for processing and analysis, and the different degrees of danger of the vehicle's surroundings are displayed through the different colors of the smart roof halo.
[0067] The intelligent roof halo warning system disclosed in this invention includes the following key technologies:
[0068] 1. Sensor technology
[0069] The system needs to be equipped with sensors such as lidar, cameras, and environmental sensors to monitor the vehicle's surroundings in real time, including obstacles, road conditions, and pedestrians. These sensors provide high-precision data, providing a reliable foundation for the system's early warning function.
[0070] 2. Data processing and analysis
[0071] The system processes and analyzes data in real time, identifying potential danger signals and assessing their severity. This requires the use of technologies such as machine learning and artificial intelligence to perform pattern recognition and feature extraction on large amounts of data, enabling intelligent perception and analysis of the environment.
[0072] 3. Communication technology
[0073] The system has good communication capabilities and can transmit and interact with other related electronic devices in the vehicle through wireless communication technologies such as Wi-Fi, Bluetooth, 4G / 5G, etc., to ensure the real-time and stability of the system;
[0074] 4. Early warning and display technology
[0075] The system has early warning and display functions, providing timely feedback to users outside the vehicle of identified danger signals. This can be achieved through LED lights installed on the roof, using different colored light rings to indicate different levels of danger, thereby increasing the user's perception and alertness of dangerous situations.
[0076] 5. Intelligent control technology
[0077] The system has intelligent control functions and automatically triggers corresponding early warning measures based on the identified danger signals, such as vehicle horns and flashing lights. This technical solution requires the design of corresponding control algorithms and logic to realize the intelligence and automation of the system.
