Abstract

The invention discloses an infrared communication auxiliary steering device which comprises an embedded microprocessor, a serial port expanded chip, an infrared communication module, a vehicle speed sampling/converting circuit, a liquid crystal display circuit and a power source circuit. The infrared communication module continues sending query information while a vehicle normally runs, and speed information is sent once confirmation information from surrounding vehicles is received. Likewise, once query information sent by the surrounding vehicles is received, confirmation information is sent, and speed information sent by the surrounding vehicles is then received. The embedded microprocessor confirms the positions of the surrounding vehicles according to the relative position information of the vehicles, compares the self speed with the speeds of the surrounding vehicles to confirm whether the vehicle is dangerous or not and displays the running conditions of the surrounding vehicles in a graphic mode. The invention effectively overcomes the visual limitation of drivers and helps the drivers to roundly master the running conditions of the surrounding vehicles so as to enhance the driving safety of the drivers.

Description

Infrared communication auxiliary steering device
Technical field
The present invention relates to a kind of vehicle electronics safety device that can help chaufeur in time to understand surrounding vehicles running condition.Belong to high-performing car electronics package technical field.
Background technology
Year rank first in the world surplus the various statistics and studies show that, China's toll on traffic continuous 10, entered the period occurred frequently of road traffic accident.And the immediate cause that causes traffic accident is many-sided, and this is mainly relevant with the quality of traffic participant and road facility condition, vehicle mechanical performance.Simultaneously, along with China's economic development, the market boom, living standards of the people improve constantly, the rapid growth of wagon flow and vehicular drive personnel amount is an inexorable trend.
At present, chaufeur all is the surrounding vehicles running condition that detects by an unaided eye, because driver vision limitation, to not in range of visibility vehicle condition have no way of finding out about it, and vehicle in range of visibility is difficult to judge exactly its running velocity, comprehensive inadequately to the grasp of surrounding vehicles running condition like this, there is potential safety hazard.In harsh environment down train such as greasy weather, rainy day and nights, sighting distance shortening, low visibility, blurred vision, there is bigger potential safety hazard in more difficult observation surrounding vehicles running condition.
The objective of the invention is in order to overcome the driver vision limitation, and a kind of infrared communication that can pass through is provided, in time understand the infrared communication auxiliary steering device of surrounding vehicles running condition, to increase the traffic safety of chaufeur.
Summary of the invention
In order to achieve the above object, the present invention has adopted following technical scheme: a kind of infrared communication auxiliary steering device is provided, comprises embedded microprocessor (1), serial port extended chip (2), serial port extended chip (3), headstock infrared communication module (4), car front left side infrared communication module (5), car left rear side infrared communication module (6), tailstock infrared communication module (7), car forward right side infrared communication module (8), car right lateral side infrared communication module (9), speed of a motor vehicle sampling/change-over circuit (10), liquid crystal display circuit (11) and power circuit (12).In the described infrared communication auxiliary steering device, headstock infrared communication module (4) is installed in the head of vehicle, car front left side infrared communication module (5) is installed in the front left side of vehicle, car left rear side infrared communication module (6) is installed in the left rear side of vehicle, tailstock infrared communication module (7) is installed in the afterbody of vehicle, car forward right side infrared communication module (8) is installed in the forward right side of vehicle, car right lateral side infrared communication module (9) is installed in the right lateral side of vehicle, and 6 infrared communication module are installed on the same horizontal surface.
The present invention can realize infrared communication between the vehicle, all infrared communication module can adopt asynchronous communication means with the surrounding vehicles infrared communication module, transmit the communication information mutually, the communication information comprises vehicle, running velocity and the azimuth information of surrounding vehicles, and azimuth information refers to that the infrared communication module that sends (or acceptance) information is installed in the orientation of vehicle; Embedded microprocessor (1) is determined the position of surrounding vehicles according to the relative azimuth information of vehicle, again according to the sample comparison of self speed of surrounding vehicles speed and speed of a motor vehicle sampling/change-over circuit (10), determine whether vehicle is dangerous, liquid crystal display circuit (11) shows surrounding vehicles running condition with graphics mode; Overcome the driver vision limitation so effectively, help chaufeur more fully to grasp surrounding vehicles running condition, increase the traffic safety of chaufeur.
Description of drawings
Accompanying drawing is the principle schematic of infrared communication auxiliary steering device.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
Embedded microprocessor (1) has the dual serial mouth, and the communication information of transmission transmits cooresponding infrared communication module by serial port extended chip (2) or serial port extended chip (3).
The communication information is divided into status information and velocity information, and wherein status information comprises Query Information, confirmation and static information.Confirmation only contains azimuth information, static information contains stationary vehicle and azimuth information, velocity information contains velocity magnitude and azimuth information, and Query Information contains vehicle and azimuth information, and vehicle is divided into four classes: full size vehicle, medium sized vehicle, dilly and other vehicles.
When vehicle normally moves, speed of a motor vehicle sampling/change-over circuit (10) obtains the instantaneous velocity of vehicle, headstock infrared communication module (4), car front left side infrared communication module (5), car left rear side infrared communication module (6), tailstock infrared communication module (7), car forward right side infrared communication module (8), car right lateral side infrared communication module (9) work alone separately, do not stop paying out and send Query Information, in case receive affirmation information, again transmission speed information from surrounding vehicles; Equally,, just send confirmation, accept the velocity information that surrounding vehicles sends again in case receive the Query Information that surrounding vehicles sends.Embedded microprocessor (1) is determined the position of surrounding vehicles according to the relative azimuth information of vehicle, again according to the comparison of surrounding vehicles speed and self speed, determine whether vehicle is dangerous, liquid crystal display circuit (11) shows surrounding vehicles running condition with graphics mode.
The vehicle et out of order, when stopping on the road, all infrared communication module are not stopped paying out the static information of sending, and remind the vehicle that passes through to take care.
