Description

Driver drowsy alarm logging device

Technical field

The utility model belongs to a kind of vehicle driving safety device, and concrete is to be used to be installed in the vehicle cab, by monitoring driving person's situation and the related data of driving nictation, comes to the driver with corresponding warning, to guarantee the device of traffic safety.

Background technology

The driving of automobile and various vehicles is a kind of work that is very easy to occur accident, and occuring frequently of various traffic hazards causes a lot of materials and the loss of spirit for litigant and society.So how to improve the security of vehicle, how to prevent driver's driving accident, be numerous Railway Car Plant man, vehicle supervision department and each extensive concern of society and do one's utmost the problem that idea solves.Occurring aspect the outfit of the manufacturing and designing of vehicle, various safety features much about improving the technology of traffic safety.These technology all are about the performance of improving car, brake control, aspect such as crashproof mostly, about less with the caution aspect of driver's monitoring.And in real life, because driver tired driving, drive when intoxicated and the driving accident that causes is very many, and this accident often causes very serious consequence.Therefore, a kind of driving condition and mental status that can monitoring driving person be proposed, in time find driver's the improper state of mind, in time warn, in time correct and stop driver's dangerous driving state, prevent trouble before it happens, the generation that tries to forestall traffic accidents obviously is very necessary and important.

The utility model content

The purpose of this utility model is at the problems referred to above, a kind of driver drowsy alarm logging device is proposed, this device is provided with camera, driving situation sensors, data processing module and displayed record parts, by in time obtaining and analyze the signal data of driver and driving situation, discovery in time may cause the dangerous situation of driving, and timely alerting drivers, make it to take measures in advance, with the generation that tries to forestall traffic accidents.This device control is flexible, and the automaticity height has stronger practicality.

The purpose of this utility model is achieved through the following technical solutions: a kind of driver drowsy alarm logging device, mainly comprise: vision signal parts, driving status signals parts, Signal Processing Element and video/audio output block, it is characterized in that: described vision signal parts mainly are made up of camera and rate signals control infrared light supply, and they are placed in the position of pilothouse facing to driver's head; Described driving status signals parts mainly are made up of the driving situation sensors group that vehicle speed sensor, car turning sensor and brake sensor etc. are formed, and they are arranged on the region of interest of car; Signal Processing Element mainly is made up of upper signal processing module, DSP data processing module, scrambler, clock module, vision signal A/D chip, vision signal D/A chip, storer, sound signal storer, sound signal D/A chip; Also have LCD and audio amplifier in addition; The signal of described driving situation sensors group sends described upper signal processing module to through described scrambler, and clock module is connected with upper signal processing module, and the clock signal that provides of whole device is provided; The output signal of this upper signal processor is connected with the inlet of DSP data processing module; The vision signal that described camera and infrared light supply produce sends the DSP data processing module to through vision signal A/D module, sends LCD through DSP data processing module processed video signal to through vision signal D/A module; The Audio Alert signal of described sound signal storer sends described loudspeaker to through sound signal D/A module after the DSP data processor extracts; Described storer is connected with the DSP data processing module, and the information with the driver is sailed in the storage driving.

After camera and infrared light supply obtain driver's head image signal, give DSP data processing module through analog to digital conversion, the DSP data processing module is by the execution analysis process software, draw driver's situation nictation, image after will handling is on the one hand issued display and is shown, judge its sleepy situation according to driver's situation nictation on the other hand, taking out the corresponding warning sound signal in the audio memory gives loudspeaker and sounds, with alerting drivers, and the driving situation is stored in the storer simultaneously notes.

The utility model is owing to adopted the structure of utilizing rate signals control infrared light supply and camera to obtain vision signal, and more weak infrared ray is done light source, is not subjected to the influence of external environment condition light, so signal stabilization is reliable; Owing in the DSP data processing module, be provided with the expert system of Flame Image Process, can analyze the situation of being obtained and the information of driving situation nictation comparatively exactly, in time find driver's sleepy situation, and propose caution to the driver; The utility model novel structure, stable performance is the very strong monitoring driving person of a kind of practicality, effectively prevents the device of traffic hazard.
