Embodiment

[0063] According to the above design scheme, realize an experimental demonstration system as an embodiment, its hardware circuit diagram is as follows figure 2 shown.

[0064] In this embodiment, the main control module selects the GD32407V-START single-chip microcomputer. After the system initializes the serial port and the interrupt configuration, it starts the DMA of the serial port UART2 (referred to as the GPS serial port) connected to the GPS for receiving GPS datagrams.

[0065] In this embodiment, the millimeter-wave radar module uses AWR1843BOOST, and AWR1843BOOST provides two sets of 20-pin connectors for connecting external devices. Not only can TTL serial port, SPI, RS232 and other methods communicate with external devices, but also use the The provided 5V and 3.3V outputs provide power for external devices. The internal development is mainly based on the mmwave sdk provided by TI. The control command is issued by the external controller (External Processor / Cont...

Abstract

The invention discloses a roadbed automatic driving auxiliary detection system and a control method thereof. The system comprises a millimeter-wave radar module, a main control module, a communication module, a GPS module, a cloud server and a vehicle-mounted terminal, the main control module is connected with the millimeter-wave radar module and the GPS module and controls the millimeter-wave radar module and the GPS module to work; and radar detection data and GPS data are acquired, repackaged and sent to a cloud server through the communication module. According to an existing millimeter wave radar principle, a DBCAN clustering algorithm and an extended Kalman filtering algorithm, movement conditions of vehicles and pedestrians on a road are monitored in real time, and positions and movement information of the vehicles and the pedestrians around a region where a driver and an automatic driving system are located can be provided for the driver and the automatic driving system, so that blind areas existing in observation are reduced, the timeliness of information transmission in a high-speed driving scene is guaranteed, safe driving is facilitated, and therefore traffic travel is more efficient, convenient and safe.

Description

technical field [0001] The invention relates to the traffic monitoring field, and relates to a subgrade automatic driving auxiliary detection system and a control method thereof. Background technique [0002] The real-time monitoring and dispatching control of traffic conditions is an effective measure to prevent most traffic accidents from the root cause. Nowadays, intelligent traffic monitoring system based on traffic infrastructure has become an effective solution. The intelligent traffic detection system can monitor the position and speed of vehicles on the road in real time, count the number of vehicles in the section, and provide corresponding position information. Millimeter-wave radar has the characteristics of being able to measure distances and speeds of multiple objects and being free from interference from weather and lighting environmental factors, which makes it an emerging technology in the field of automobile and traffic monitoring. [0003] V2X (Vehicle to...
