PDA (Personal Digital Assistant)-based overall speed detecting and data processing method

Abstract

The invention discloses a PDA (Personal Digital Assistant)-based overall speed detecting and data processing method which comprises the steps of: inputting a detection station and stake number data through a PDA; when running vehicles arrive in sight, inputting the license plate numbers and vehicle type data through the PDA; when the running vehicles just arrive at the detection station, recording and displaying the moments when the running vehicles pass through the detection station through the PDA; after the running vehicles pass through the detection state, counting the number of the running vehicles running through the detection station and the sample numbers of a certain vehicle type by the PDA; acquiring data stored in PDAs at a plurality of detection stations by an upper computer and storing the data in an upper computer disc; and analyzing the data by the upper computer to obtain an analysis result and then displaying the analysis result in real time. The method provided by the invention is reasonable in design, convenient for use and operation, high in intellectualization degree, high in data acquiring and processing efficiency, high in data accuracy and strong in practicability, manpower and material resources are saved, and the method is convenient for application and use.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a PDA-based interval vehicle speed detection and data processing method. Background technique [0002] With the rapid development of the economy, automobiles, as an important means of transportation for human beings, are increasing rapidly, which leads to the rapid construction of highways. Highways not only bring great convenience to people's transportation, but also greatly promote the development of the national economy. Knowing the running characteristics of automobiles on the road is the basic content of statistical analysis of traffic transportation, traffic safety evaluation, and traffic flow monitoring. Interval vehicle speed can reflect the operating characteristics of vehicles in the section, and its rapid detection and processing is an important content in the field of transportation research. [0003] In the interval speed detection test of the ex...
