control "hardware in the ring" simulation diagnosis system (hereinafter
referred to as "diagnostic system"), is based on a "hardware in the
ring" simulation environment, for traffic signal control effect
monitoring, evaluation and diagnosis system. The
diagnostic system uses computer simulation to enrich the traffic
simulation test environment, with a variety of diagnostic parameters and
indicators as the core, providing online and offline diagnostic
results. The diagnostic system includes diagnostic and diagnostic analysis software. The
diagnostic device is 100 * 100 * 100 with a 7-inch touch screen
portable device, connecting the signal control machine and the computer.
(1) "bridge": connecting
the signal and the computer, real-time bi-directional transmission
detector information and timing information, so that the signal and the
simulation environment to form a closed loop, continuous operation;
monitoring: real-time monitoring of the intersection of running and
online diagnosis, the user through the display to see the intersection
of real-time detector usage and signal timing information, online
observation of diagnostic trends;
(3) record: record the intersection of running data for offline diagnosis. Diagnostic analysis software for PC-side off-line further diagnostic analysis tool.
The main function：
calculation: the use of diagnostic equipment recorded at the
intersection of running data, calculate the indicators;
<2> diagnostic information detailed, diverse inquiries: single-index multi-object, single-object multi-indicators
Diagnostic report is automatically generated: report to different users
in different forms, such as annual reports, monthly reports and daily
newspapers. Our diagnostic system as the signal
control machine "top", the existing intelligent control system to
upgrade, to achieve the transformation of the existing system without
the signal and do not interfere with the traffic conditions, the signal
control system for diagnostic evaluation , Given the "medical report" to guide further operational decisions.
(1) "Hardware in the
ring": based on "hardware in the ring" simulation, to provide a variety
of test scenarios, flexible, low cost and efficient evaluation, can also
be used before the signal into the use of test evaluation.
4 categories, 24 diagnostic parameters or indicators: diagnostic index
system is perfect, rich indicators, new perspective, from the operation
process, efficiency and safety and other aspects to reflect the quality
of signal control.
(3) Online & Offline:
Diagnostic and Diagnostic Analysis Software for online and offline,
real-time and historical, easy and detailed query, diagnostics and
(4) diagnostic report: report
automatically generated by different types, the content of the focus and
professional differences, from the general masses to professionals, for
all types of people.
control equipment manufacturers, research institutions and traffic
control departments, as a traffic management and control algorithm
(2) student lab, as a communication professional teaching demonstration tool.
