Abstract

The present invention relates to a system for monitoring dynamic weighing of vehicles, speed of vehicles on lanes, applied to the monitoring of road traffic variables, traffic control, maintenance and infrastructure, diagnosis of traffic problems, on toll roads and in the application of fines in irregular traffic situations, through the technology of optical fiber, with punctual and quasi-distributed sensors, that allow for quick response, to be encapsulated, to ease the process of installation and/or to protect the sensing optical fiber, to employ specific materials, they can be assembled in advanced configurations of optical networks and with the advantages of having a lower cost and prolonged shelf-life when compared to the other technologies; the sensors can be multiplexed, have high spatial resolution across the pavement, and manufacturing technology is simple and inexpensive and transferable due to associated costs.

Abstract

The present invention relates to the technical field of systems for measurement of weight load and other physical variables in vehicles and/or containers, comprising a system of sensing and monitoring of their conditions, instantaneous or not. Consists of an external data collection subsystem (SSI) with module with sensing network (1), signal transduction module (2) and connection module (3); of a data processing and reading subsystem (SSII) with energizing module (4); reading and data acquisition module (5); processing and memory module (6); and data transmission subsystem (SSIII) with data communication module (7). The system has advantages, does not present false sensor measurements, that allow wide multiplexing, no electricity, high signal and there is no electromagnetic interference, they are robust, do not suffer corrosion and do not fail due to vibration and mechanical impacts.
