Abstract
With the development of auto detection
technology, applications of computer control system in
automobile comprehensive performance test has developed
into a new stage. Also the paper elaborates automobile
comprehensive performance testing automatic control
system's designing mentality, system composition, test
process, and the characteristics of the system and function.
INTRODUCTION
Along with the development of modern transportation,
car quantities is increase rapidly, traffic safety of vehicles,
environmental protection, energy conservation and
emission reduction has become a very serious problem.
Automobile comprehensive performance testing is an
important content of implementation of vehicle
management for transportation departments at all levels.
The current domestic examination of the automobile
synthesize function is only based on manual inspection or
half-automatic inspection. So how to realize the fullautomatic
inspection of the automobile synthesize
function, that is quite attentioned by the corporation and
academy who are very paying attention to the
development of automobile inspection equipments at
percent. Making use of modern electronics technique,
computer and its network correspondence techniques, to
develop the completely automatic vehicles overall
performance inspecting line has become one inevitable
trend.
SUMMARY OF SYSTEM
Automobile comprehensive performance test line is the
testing system as a comprehensive use of modern
detection technology, electronic technology, computer
technology for automobile implementation nondismantlement
testing and diagnostic testing. It can
diagnose and test all kinds of vehicle performance
parameter indoors , and detect malfunction status
providing reliable basis for the comprehensive and
accurate evaluation of performance and technique of car's
situation. Automobile comprehensive performance lines
can undertake the test of vehicle performance, reliability
and safety of economy, environmental management etc.
DESIGNING MENTALITY OF THE SYSTEM
In order to succeed in the breakthrough of performance
testing equipment assembly and online method,
distributed computer test system will be applied in
automobile comprehensive performance testing process.
Then we will connect various testing equipments of
respective operation modes and output data by computers,
employing master computer and slave computer, to form a
whole, then realize the concentrated automatic control and
inspection the real-time data acquisition and processing,
with the completion of each stage detection task rapidly,
accurately and automatically[2].
System testing lines includes one master computer and
three slave computer and a zero station machine, each
slave computer is responsible for testing one operating
station, and each operating station has at least two testing
points. The first operating station mainly detects speed,
tail gas and chassis. The second operating station mainly
inspects braking performance by the axle load
measurement platform and brake testboard.The third one
operating station mainly measures engine performance,
side slip, lighting, sound level, chassis dynamometer and
other items.
CONCLUSIONS
The computer control system is the efficient and
modern means for vehicle performance testing. Through
computer networks, it also can accomplish information
resources sharing, hardware resources sharing and
software resource sharing. Furthermore, it has realized the
data exchange and information communication between
check stations and road transportation management
agency, check stations and check stations within the
province. Not only has it strengthened the management
department's supervision to testing service, but also has
improved the self-testing level of check stations.
