Digital track gauge (electronic track gauge)

Product Overview

　　The BZ-DGJC series (including four types of electronic gauges: A, B, J, and C) is an innovation in railway track geometry dimension detection. It uses advanced sensing technology and optimized data processing algorithms to measure the level (superelevation) and gauge of the track and switch; Using computer comprehensive processing technology, track severalWhat size should be scientifically managed.

　　two Scope of application

　　Applicable to railway straight lines, curves (including transition curves), and turnouts (single) of various speed levelsHorizontal (superelevation) andTrack gauge inspection.

　　three product structure

　　It consists of four parts: mechanical components, electronic measuring instruments (including ultra-high sensors), displacement sensors, batteries, and chargers. The measuring instrument is installed on the groove of the ruler body, close to the side of the movable measuring head. The height and width of the instrument box are slightly larger than those of the ruler body. The ultra-high sensor is located in the instrument housing, while the displacement sensor is located in the instrumentBottom left side of the box. The battery box is in the middle of the ruler. The external dimensions are 1594 * 30 * 206.

　　four Main functions

　　(1) Measure the level (superelevation) and gauge of the track, and set the starting kilometer mark (0~)After 99999.999 km, continuous measurements can be taken at any interval;

　　(2) Measure the level, gauge, inspection interval, and back protection distance of various types of turnouts, and measure them in both forward and reverse orderThe quantity can be switched, and the new type of switch can be edited;

　　(3) Store detection data, upload it to the management workstation for display in the form of tables and curves, automatically diagnose faults, and remotely query and print data (this function is only applicable to management type measuring tools)Be prepared.

　　five Main Features

　　(1) Applicable to all types of turnouts (including high-speed turnouts);

　　(2) High measurement accuracy: CType is0 Grade accuracy, suitable for operating at speeds not too highAt 350KmLine measurement;AType isLevel 1 accuracy, suitable for line measurement with a running speed not exceeding 250km/h; The J-type has a level 2 accuracy and is suitable for operating at speeds not exceeding 160km/hLine measurement;

　　（3）OLEDChinese character display, menu prompts, clear and intuitive;

　　(4) The calibration process is automatic and fast, with a calibration operation time of ≤ 2Minutes, improve work efficiency, and achieve scientific management;

　　（5) Auxiliary functions: It has the function of assisting in the judgment of small gauge values and setting target values during line maintenance.
