Problems solved by technology

Many domestic and foreign cases of drivers falling asleep with their eyes open fully exposed the non-universal nature of the PERCLOS drowsiness monitoring solution; The frequency of Lane Departure false alarms greatly reduces the early warning effect of the scheme; the driver's physiological parameter measurement method faces technical difficulties such as parameter scheme selection
However, the existing driving fatigue intervention programs are generally physical methods, unable to intervene from the fatigue mechanism level and the post-intervention effect is severely limited

Abstract

The invention provides a portable driving fatigue monitoring and intervention device. The device comprises a driver wearing module provided with an EEG+MI fatigue monitoring unit and a tDCS+ physicalwarning fatigue intervention unit and a vehicle module formed by a non-invasive BCI central control unit and a vehicle power supply, and the driver wearing module is wirelessly connected with the vehicle module through a wireless energy supply module of the driver wearing module. The monitoring and intervention steps include: 1) connecting a device; 2) obtaining and storing a driver EEG signal; 3)forming a composite signal of driving fatigue monitoring; 4) transmitting a corresponding instruction to the tDCS+ physical warning fatigue intervention unit by a determination result; and 5) starting operation of the tDCS+ physical warning fatigue intervention unit when the driver fatigue state is determined to be reached or a preset fatigue level threshold is exceeded. Hidden risks of fatigue driving of drivers can be eliminated, drivers can calmly avoid risks, and the generation probability of traffic accidents caused by fatigue can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of driving monitoring, and specifically relates to a portable driving fatigue monitoring and intervention device and a method thereof, which can monitor the driver's EEG state in real time, and perform transcranial direct current stimulation to effectively intervene in driving fatigue when fatigue driving is found, and can effectively treat the driver. Effectively avoid the risk of fatigue driving, Background technique [0002] According to the "2019-2025 China Traffic Accident Site Investigation and Rescue Equipment Industry Market Special Research and Investment Strategy Research Report" statistics, in 2017, there were 139,412 automobile traffic accidents nationwide, with 46,817 deaths; 139,180 injuries and direct property losses 1039.78 million yuan. Taking the traffic accident statistics of the Huaian section of the Beijing-Shanghai Expressway in 2016 as a sample, there were 787 traffic accidents throug...
