Abstract

The invention discloses a dynamic railway scale high-speed data acquisition device and a method, so as to solve problems that the device needs to be highly configured as dynamic data are unreliably measured. The device comprises a measurement terminal device arranged in a measurement field and a control device arranged in a control room, wherein the measurement terminal device comprises a weighing platform arranged below two bearing rails, a sensor module and a support; and the control device comprises a rack, a power supply module, a weighing module, a serial port communication module, a CPU module and a metering module. The invention also discloses a dynamic railway scale data acquisition method based on a PLC program and a dynamic railway scale weighing method. The problems that an ISA interface card needs to be arranged in a computer, and an industrial computer needs to be used can be solved, assembly requirements on the computer are reduced, self improvements according to needs can be carried out, the device does not depend on a weighing machine factory, the application cost is reduced, the use is flexible, universality is strong, and programming is convenient.

Description

technical field [0001] The invention relates to the technical field of data acquisition systems, in particular to a method for high-speed data acquisition of a dynamic track scale. Background technique [0002] In the field of weighing, dynamic rail scales are generally composed of load cells, weighing tables, data acquisition instruments and computer systems. [0003] As an important part of the dynamic rail scale, the data acquisition instrument completes the amplification, filtering, analog-to-digital conversion and high-speed output of the weighing signal. Its sampling speed, accuracy, and anti-interference performance directly determine the measurement of the dynamic rail scale. performance. After the data acquisition instrument completes the data conversion, it needs to communicate with the computer, and the computer completes the data collection and processing, and issues the measurement results. [0004] The data acquisition instruments of weighing instrument manuf...
