Problems solved by technology

However, the above method has many defects
One is that the judgment is too simple and does not take into account the personal characteristics of the driver
The second is that the judgment method is also through conventional detection of eye opening and closing, heart rate and other parameters, and it is difficult to really play a role when the driver intentionally avoids supervision.
The third is that only a simple warning is carried out, which cannot really play a role in improving driving safety.

Embodiment 1

[0026] This embodiment provides a safe driving method, please refer to the appendix figure 1 , the system can monitor the driver's driving status online in real time around the clock, and immediately implement graded alarms and processing when the driver's vision deviation, lack of energy, fatigue, distraction and other phenomena are detected. The specific processing flow is as follows.

[0027] S1 trains the driver on the fatigue state and obtains a personalized fatigue judgment threshold.

[0028] Since the driving state of the driver is closely related to the assessment results, it may happen that the driver deliberately violates the physiological laws in order to avoid the assessment. For example, in the prior art, only by detecting the frequency of eye opening and closing to determine whether the driver is driving fatigued, in order to avoid detection, the train driver may forcefully hold his eyes without blinking in a sleepy state, but his head may not be under control ...

Embodiment 2

[0049] This embodiment provides a train safety driving system, including a training unit, an acquisition unit, an analysis unit, a distraction judgment unit, and an auxiliary driving unit.

[0050] Training unit: Train the driver on fatigue state to obtain a personalized fatigue judgment threshold.

[0051] Since the driving state of the driver is closely related to the assessment results, it may happen that the driver deliberately violates the physiological laws in order to avoid the assessment. For example, in the prior art, only by detecting the frequency of eye opening and closing to determine whether the driver is driving fatigued, in order to avoid detection, the train driver may forcefully hold his eyes without blinking in a sleepy state, but his head may not be under control at this time. up and down movement. In order to more accurately judge the fatigue state of the driver, it is necessary to carry out the training of the fatigue state. And because the physiologica...

Abstract

The invention discloses a train safe driving method and system, and the method comprises the steps: carrying out the fatigue state training of a driver, and obtaining a personalized fatigue judgment threshold value; obtaining the driving habit of the driver on the fixed route in advance; collecting a face video of the driver in real time in the driving process, and analyzing the collected video image by using a video analysis technology; acquiring current driving data of the driver, comparing the current driving data with driving habits of the driver, and if the deviation degree between the current driving data and the driving habits reaches a preset deviation threshold value, judging that the driver is in a distracted state. And performing corresponding auxiliary driving operation according to a comparison result of the video image analysis result and the driving data. The driver state can be recognized in real time, and driving safety is guaranteed.

Description

technical field [0001] The invention relates to the field of safe operation of trains, in particular to a method and system for safe driving. Background technique [0002] Railway is the main artery of my country's national economy and plays a pivotal role in national economic construction. The rapid development of science and technology has continuously promoted the improvement and progress of my country's railway modernization level. However, the traditional railway transportation system still faces many new problems, and one of the most prominent problems is driving safety. [0003] The ride status of the locomotive driver is directly related to the driving safety. Due to various reasons such as physical discomfort, fatigue driving, intermittent lookout, night driving, etc., individual locomotive drivers may experience irregularities such as inattention, poor working condition, and even dozing off during the ride-hailing process. If the locomotive driver fails to detec...
