The step developed with Global Urbanization, urban rail transit vehicles become increasingly in daily life
Popularization, the resident of present large- and-medium size cities is possible to daily all can be using city rail vehicle as the vehicles, while city rail vehicle
The pressure of extreme portions urban transportation is carried, especially daily period on and off duty, its unit carrying capacity is even more surprising.We
Enjoy city rail vehicle to we bring it is convenient while, the problem of also facing the security of city rail traffic, this is just
It is required that we are made more perfect in the security performance detection of city rail vehicle.
In many security performances of city rail vehicle, the performance detection of vehicle braking force is undoubtedly an important ring.
Because can this directly influence the city rail vehicle quickly run and controlled when running into dangerous situation within the very first time in safe condition
Under.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of more reasonable more accurate city rail vehicle braking ability
Measurement apparatus and method, can quickly, intuitively quantify one city rail vehicle braking ability of weighbridge amount.
In order to solve this technical problem, the technical solution adopted by the present invention is as follows：
A kind of city rail vehicle braking ability measurement apparatus, is installed on city rail vehicle to be measured and test is interval, including radar is surveyed
Fast instrument, laser range finder, CPU and with reference to reflecting plate；
Described radar meter is fixedly installed in described city rail vehicle bottom to be measured, using roadbed ground as testing the speed
Object of reference, measures the travel speed of the city rail vehicle to be measured in real time；
It is described to be fixedly installed on reference to reflecting plate along the remote of the test interval orbit of the city rail vehicle travel direction to be measured
Rectify front；The laser range finder is fixedly installed on the headstock front end of the city rail vehicle to be measured, and test the speed laser during its work
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, and the radar is obtained in real time
Tachymeter and the travel speed and the city rail vehicle to be measured of the city rail vehicle to be measured of laser range finder measurement and the ginseng
According to the distance between reflecting plate；By setting speed threshold value, the measurement city rail vehicle is calculated from specified travel speed to safety
The braking distance of speed, so as to compare the braking ability for evaluating the city rail vehicle.
Simultaneously city rail vehicle braking ability measurement is carried out the invention provides the device described in a kind of utilization claim 1
Method, its step includes：
A, some travel speeds and some safe speeds are set in CPU；
B, the initiating terminal by the city rail vehicle to be measured in the test interval raise speed to First Speed and start braking
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 to evaluate the braking ability of the city rail vehicle to be measured from reference point.
More preferably, described some travel speeds are 100km/h, 80km/h, 60km/h and 40km/h, and described is some
Safe speed is 10km/h and 0km/h.
The city rail vehicle braking ability measurement apparatus that the present invention is provided is ingenious and reasonable, if being set by CPU
After dry threshold speed, CPU can gather city rail vehicle in real time and be issued to specified travel speed and peace in on-position
The positional distance value of vehicle when full speed is spent, so as to calculate system of the city rail vehicle required for from specified travel speed to safe speed
Dynamic distance, to contrast the braking ability for evaluating city rail vehicle.
From the point of view of the city rail traffic route that the country has been runed, average station spacing is universal between 1-2km, part circuit
Station spacing is larger, reaches more than 5km, most of highest running speed of train in 80km/h, up to 100km/h, travelling is flat
Equal speed is generally 35km/h or so.And city rail vehicle is also difference, institute in different velocity bands its braking ability
Several travel speeds between 100km/h to 40km/h are set in CPU with the present invention, with urban rail of testing and assessing
Vehicle is in each travel speed region to the braking distance required for safe speed；Simultaneously because urban rail transit vehicles are met
The dangerous situation arrived is different, and its urgency level and risk avoidance measures grade are different, so city rail vehicle exists when running into dangerous situation
The requirement for braking the safe speed reached is needed also to be not quite similar in the very first time, so the present invention sets several safety speed
Angle value, can be 10km/h or 0km/h, to provide more comprehensively city rail vehicle safety braking performance data, so as to urban rail
More careful, more scientific evaluation and grasp that the stopping power of vehicle reaches, is that more and more flourishing, flouring urban track traffic is carried
For safety guarantee.
