Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Such as figure 1As shown, a structural schematic diagram of the steering wheel in the driver stress discrimination system of the present invention is given. The two photoelectric pulse sensors shown are arranged on both sides of the steering wheel 1, and their structures and detection principles are the same. Each photoelectric pulse sensor is composed of a light source 4 and a photosensitive element 5. Both sides of the steering wheel are provided with a first notch 2 and a second notch 3. The light source 4 is located in the first notch 2, and the photosensitive element 5 is located in the second notch 3. Among them, the first notch 2 is adjacent to the second notch 3, so that the light emitted by the light source 4 is absorbed and reflected by the finger, and then irradiates on the photosensitive element 5, so as to realize the detection of th...

Abstract

The invention discloses a system for distinguishing the stress of a driver based on electrocardiosignals and geographic information, which is characterized by comprising a photoelectric pulse sensor and a circuit part, and a micro controller is connected with a vehicle sensor and a GPRS or Beidou navigation system; whether the current driving state is secure is evaluated according to electrocardiogram information, vehicle operating state and traffic environment information acquired by the micro controller, and when the current driving state is insecure, an alarm is made; and the distinguishing method comprises the following steps: a) determining signal input; b) acquiring electrocardiosignals; c) calculating a RR interval; d) calculating the powers of high and low frequency bands; e) determining whether mutation occurs in the RR interval; f) determining whether the powers of high and low frequency bands exceed a threshold; g) acquiring traffic environment information; and h) making a voice alarm. According to the system and method disclosed by the invention, by using the combination of acquired electrocardiosignals and physiological indexes, the stress of the driver is distinguished, so that the driving safety status can be scientifically evaluated and forecasted, therefore, the system and method disclosed by the invention have remarkable beneficial effects, and are convenient for popularization and application.

Description

technical field [0001] The present invention relates to a driver stress discrimination system and method based on electrocardiographic signals and geographical information, and more specifically, relates to a system and method for evaluating whether a driver is A stress discrimination system and method capable of continuing safe driving. Background technique [0002] Because the traffic environment in our country is very complicated, the driver cannot completely avoid the occurrence of emergencies while driving. The high stress state of physiology, psychology and behavior shown by the driver in this sudden, unexpected danger and emergency situation, such as rapid heartbeat, unconscious knee jerk reflex, spinal reflex and other physiological reactions; 1. Psychological reactions of fear; behavioral reactions such as narrow cognition of complex traffic environments, prolonged information processing time, and misjudgment. This state has a great influence on driving behaviour....
