Pavement Management System with Real time Microprocessor‐Based Computation
This article is the second part of a two‐part article concerned with observing cracks on the pavement surface with very specialized microcomputer equipment mounted in a van type vehicle moving at road speeds. As one would imagine, the computing speed required to do the job is very high. In fact, to adequately handle this particular application, three camera systems, each with its own Motorola 68020 microprocessor, are required to work in parallel as the 12‐foot lane width is observed. In the first part of this article, an overview of the following technical requirements was presented [5]: 1) sensor data rate requirements, 2) hardware and software approaches, 3) pavement rating procedures, 4) system block diagram, and 5) real‐time computer algorithms.This article will extend and update previous pavement monitoring concepts while looking at the microprocessor requirements of moving a huge amount of processed data through the system. In addition, a host microprocessor (a Motorola 68010) will be responsible for system housekeeping and formatting all of the processed data for future use. Some introductory comments about the pavement monitoring system appear again for continuity.
