Optical-fiber sensing type railroad track scale and its data processing method

Abstract

This invention relates to a railroad track scale of a fiber sensing type including: a spandrel girder unit, a data collection unit, a weighing data process unit and a data transmission unit, in which, the spandrel girder unit is the on-line used rail of railway, said data collection unit includes: a fiber sensor and a fiber modem instrument, said fiber sensor is set on said rail to get the light wave signal, said fiber modem instrument is connected with the fiber sensor to convert the light wave signals to the strain signal of the rail, said weighing data process unit is connected with the data collection unit to convert the strain signal to weight and the data transmission unit is used for transmitting data.

Description

technical field [0001] The present invention relates to a metering device, in particular to a rail weighing device and its data processing which use optical fiber sensing technology to weigh goods transported by trains in stations, freight yards, ports, and industrial and mining enterprises. method. Background technique [0002] Rail scale equipment is divided into two forms: broken rail and continuous rail. The broken rail type track scale needs to be cut off on the continuous rail, which limits the speed of the train passing, and the installation period is long and the engineering cost is high. The non-stop track scale does not need to cut off the rails, which increases the speed of the train when it is overbalanced, and the engineering time and cost are greatly reduced compared with the broken track scale. At present, the continuous track track scale has been widely used. [0003] Usually, the continuous rail track scale needs to use pressure and shear sensors to form a...

Problems solved by technology

[0003] Usually, the continuous rail track scale needs to use pressure and shear sensors to form a measurement system. The shear sensor is generally installed in the waist of the rail, which seriously affects the strength of the rail and has an impact on the safety of the train. Moreover, there is usually a high-voltage power grid near the railway. It is easy to form an electromagnetic field, which brings great interference to the measurement results of the resistance strain sensor, and a signal lightning protection device is required to ensure the safety of the measuring element;
