Description

A kind of mountainous area highway actual road test ECT signal detection system Data processing method
The application is divisional application, the application number of original application：2015101995952, the applying date：2015-04-24, invention Patent name：A kind of data processing method of mountainous area highway actual road test signal detection system.
Technical field
The present invention relates to data acquisition process technical field, more particularly to a kind of mountainous area highway actual road test starts The data processing method of machine coolant temperature signal detection system.
Background technology
With economic development in an all-round way at full speed, the expressway construction of China achieves achievement well.China's geography ring Border is extremely enriched, and in order to accelerate the traffic route of connection different zones, China has built many mountainous area highways.Mountain area is high Fast highway road environment is complicated, Frequent Accidents, and the scientific research personnel of China will often do some actual road tests, gather related data, Ground road data research highway safety evaluation, speed feature, the adaptive cruise based on road alignment etc. is carried out In studying carefully, often experiment is acquired to signals such as speed, acceleration, the vehicle lateral accelerations of road vehicle traveling, with To signal of the vehicle in the travel corresponding to road alignment pile No., i.e., it is to be understood that vehicle correspondence pile No. in road alignment Every bit signal.Coherent signal of the vehicle at a certain pile No. position of road alignment is specified to have very important significance.
Current existing actual road test acquisition mode can collect associated vehicle signal and the warp corresponding to the signal Degree, latitude and elevation, but be difficult for the positional informations such as the longitude corresponding to the coherent signal of collection, latitude to correspond to road alignment Pile No. on, not display road pile No. this project in its data output project.After prior art is gathered data, enter Row artificial treatment, is corresponded in the linear pile No. of related roads using positional information manual modes such as the longitudes and latitude for gathering, Not only the degree of accuracy is not high for such mode, and the efficiency of data processing is very low, while when mountainous area highway tunnel is gathered Due to the loss of gps signal, it is impossible to obtain the position signallings such as longitude and latitude in tunnel, the missing of data acquisition will be caused, after giving Phase research brings greatly puzzlement.Generally speaking, the actual road test ECT signal that prior art is gathered, It is that the signal just gathered using longitude and latitude information is mapped, it is rarely seen that correspondence is carried out with road pile No. information.
Mountainous area highway differs markedly from Expressway in Plain, with some outstanding features, the drop of its height Very big, such as the highway in Xi'an to Hanzhong, its elevation drop has reached more than 1,000 meters.It is larger for this class elevation drop Mountainous area highway, we generally only need to know the elevation of certain point on road, just can easily obtain elevation institute right The road pile No. answered.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the invention provides a kind of mountainous area highway actual road test engine The data processing method of coolant temperature signal detection system, the method from elevation and road pile No. can corresponding relation, A pair of the actual road test ECT signal data that will conveniently can be gathered and road pile No. data 1 Should get up, while the present invention can be solved in collection mountainous area highway tunnel inner road test engine cooling liquid temperature well During degree signal, because when later data is processed caused by the missing of gps signal, there is discontinuity in data.The present invention Reasonable in design, using easy to operate, intelligence degree is high, and data acquisition and treatment effeciency are high, and data accuracy is high, saves manpower Material resources, it is practical, it is easy to promote the use of.
