Embodiment Construction

[0028] Such as figure 1 As shown, the data processing system of the present invention mainly completes functions such as data collection, processing, alarm, and data transmission, and it can be worn in various forms, such as wristbands, anklets, and armbands.

[0029] The data transmission module communicates with smart devices, vehicle systems and control platforms.

[0030] The application scenario of the present invention is to monitor the physical status of the driver during the driving operation in a sitting posture. For this reason, it is necessary to clearly determine that the driver is in the driving state before triggering data analysis and warning actions.

[0031] There are various ways that can be used to determine the driver's driving state. Because the user object of the present invention is a driver, its driving operation is a controlled behavior. Before and after the driving operation, the cloud platform system can automatically (or manually) set the driver ...

Abstract

The invention discloses a method for safely monitoring signs under a driving state of a driver and a data processing system. Normal sign data in the N times of normal driving processes of the driver are collected; a sign model is constructed through the above normal sign data, and the probability density of each data point in the sign model is calculated; the data points with the probability density smaller than the threshold value are judged as abnormal points, the rest of data points are judged as normal points, the space formed by all the abnormal points is the driver feature state abnormalspace, and the space formed by all the normal points is the driver sign state normal space; whether newly-collected driver sign data are in the driver feature state abnormal space or not is judged, and if yes, it is judged that the sign state of the driver is abnormal; and otherwise, the sign state of the driver is normal. According to the method, the driving state of the driver can be monitoredonline in real time, alarm information can be sent out when the state of the driver is abnormal, dangerous driving is avoided, and driving safety is improved.

Description

technical field [0001] The invention relates to the field of sign data analysis, in particular to a sign safety monitoring method and a sign data processing system in a driver's driving state. Background technique [0002] Driving fatigue refers to the phenomenon that the driver's physiological function and psychological function are out of balance after driving continuously for a long time, and the driving skill declines objectively. The driver's sleep quality is poor or insufficient, and he is prone to fatigue after driving for a long time. Driving fatigue can affect various aspects such as driver's attention, feeling, consciousness, thinking, judgment, will, decision and motion. When the driver is in severe fatigue, he will often operate subconsciously or experience a short-term sleep phenomenon, and in severe cases, he will lose the ability to control the vehicle. Drunk driving (drunk driving) refers to the traffic violation behavior of driving a motor vehicle under th...
