Reference reflecting plate described in positive directive, and using it is described measured in real time as reference substance with reference to reflecting plate the city rail vehicle to be measured and
The distance between described reference reflecting plate；
The CPU is connected with the radar meter and laser range finder respectively, obtains the radar in real time
The travel speed and the city rail vehicle to be measured and the ginseng of tachymeter and the city rail vehicle to be measured of laser range finder measurement
According to the distance between reflecting plate；By setting speed threshold value, calculate and measure the city rail vehicle from specified travel speed to safety
The braking distance of speed, so as to compare the braking ability for evaluating the city rail vehicle.
When carrying out the measurement of city rail vehicle braking ability using device of the present utility model, its step includes：
A, some travel speeds and some safe speeds are set in CPU；
B, the city rail vehicle to be measured is started after the initiating terminal in the test section raises speed to First Speed and braked
System；
C, when the city rail vehicle to be measured reaches the travel speed or safe speed of any setting, phase is read in real time
The corresponding city rail vehicle to be measured is with described with reference to the distance between reflecting plate；
D, calculate and obtain from a certain travel speed to the braking distance of a certain safe speed, by the braking distance and braking away from
Compare from reference point so as to evaluate the braking ability of the city rail vehicle to be measured.
Described some travel speeds can be 100km/h, 80km/h, 60km/h and 40km/h, described some peaces
Full speed degree is 10km/h and 0km/h.
City rail vehicle braking ability measurement apparatus provided by the utility model is ingenious and reasonable, is set by CPU
After several fixed threshold speeds, CPU can gather city rail vehicle in real time and be issued to specified travel speed in on-position
With the positional distance value of vehicle during safe speed, required for calculating city rail vehicle from specified travel speed to safe speed
Braking distance, come contrast evaluation city rail vehicle braking ability.
From the point of view of the city rail traffic route runed of the country, average station spacing is generally between 1-2km, part circuit
Station spacing is larger, and it is flat in 80km/h, up to 100km/h, travelling to reach most of more than 5km, highest running speed of train
Equal speed is generally 35km/h or so.And city rail vehicle is also difference in different velocity bands its braking ability, institute
Several travel speeds between 100km/h to 40km/h are set in CPU with the utility model, with test and appraisal
City rail vehicle is in each travel speed region to the braking distance required for safe speed；Simultaneously because urban rail transit vehicles
The dangerous situation run into is different, and its urgency level and risk avoidance measures grade are different, so the urban rail car when running into dangerous situation
Need the requirement for the safe speed that braking reaches also to be not quite similar within the very first time, thus the utility model set it is some
Individual safe speed value, can be 10km/h or 0km/h, to provide more comprehensively city rail vehicle safety braking performance data, from
And more careful, more scientific evaluation and grasp are reached to the stopping power of city rail vehicle, for more and more flourishing, flouring city rail
Road traffic provides safety guarantee.
