Mountain area highway road test signal detection system

Abstract

The invention discloses a mountain area highway road test signal detection system, and the system comprises a road test signal collector, a counter, a GPS receiver, and a vehicle-mounted industrial control computer. The road test signal collector, the counter and the GPS receiver are respectively in wired or wireless connection with the vehicle-mounted industrial control computer through a data communication line or a wireless communication network. The road test signal collector is used for collecting various needed road test signals, and the road test signal collector can collect one or more types of signals, and can be configured according to the needs. The counter is used for counting the number of groups of signals collected by the road test signal collector, and facilitates the subsequent calculation. The GPS receiver is used for receiving elevation data. The interior of the vehicle-mounted industrial control computer is provided with a data analysis processing module in an integrated manner. The system is high in data processing efficiency, effectively reduces the personal errors, is high in accuracy of obtained data, and saves the manpower and human resources.

Description

[0001] This application is a divisional application, the application number of the original application: 2015101995952, the application date: 2015-04-24, the name of the invention patent: a data processing method for a mountainous expressway road test signal detection system. technical field [0002] The invention relates to the technical field of data acquisition and processing, in particular to a road test signal detection system for expressways in mountainous areas. Background technique [0003] With the rapid and comprehensive development of the economy, my country's expressway construction has made great achievements. my country's geographical environment is extremely rich. In order to speed up the traffic roads connecting different regions, many mountainous expressways have been built in our country. The road environment of mountainous highways is complex and accidents occur frequently. Chinese researchers often do some road tests to collect relevant data. In the res...

Problems solved by technology

[0004] At present, the existing road test collection methods can collect relevant vehicle signals and the corresponding longitude, latitude and elevation of the signals, but it is difficult to correspond the longitude, latitude and other position information corresponding to the collected relevant signals to the chainage of the road alignment However, the item of road stake number is not displayed in the data output item

The existing technology is to manually process the data after collecting the data, and use the collected position information such as longitude and latitude to manually map it to the relevant road alignment stake number. This method is not only not accurate, but also has a high efficiency of data processing. At the same time, due to the loss of GPS signals when collecting highway tunnels in mountainous areas, the location signals such as latitude and longitude in the tunnel cannot be obtained, which will lead to the lack of data collection and bring great troubles to later research.

Generally speaking, the road test signals collected by the prior art all use the longitude and latitude information to correspond the collected signals, and it is rare to use the road stake number information for correspondence
