Railway overload and unbalanced load rail weighbridge multipath data acquisition system with diagnosis function

Abstract

The invention discloses a railway overload and unbalanced load rail weighbridge multipath data acquisition system with a diagnosis function. The system comprises a self-checking unit, at least one data acquisition unit, a DSP unit, a backboard unit, a storage unit and a sensor. The backboard unit is provided with a clock module and is in communication connection with the data acquisition unit, theDPS unit and the sensor; and the self-checking unit is respectively connected with the sensor, the data acquisition unit and the storage unit. The clock module is used for a clock source of at leastone data acquisition unit. According to the invention, with the self-checking unit, the reliability and safety of system operation are improved; because of the clock module at the backboard unit, thesynchronism of the plurality of data acquisition units during operation is ensured and the accuracy of data acquisition is enhanced; and with a wireless communication module, data remote monitoring can be carried out rapidly and effectively and the safety coefficient of system operation is improved.

Description

technical field [0001] The invention relates to the technical field of railway transportation, in particular to a multi-channel data acquisition system for railway ultra-eccentric load track scales with a diagnostic function. Background technique [0002] The over-eccentric load rail scale plays an important role in railway freight transport. In the entire over-eccentric load rail scale system, the data acquisition system collects sensor data and performs signal processing and data analysis. [0003] At present, over-eccentric load and track scale systems, especially over-eccentric load systems, are generally unattended and lack the ability to remotely control their operating status; when multi-channel data collection often occurs out of synchronization; at the same time, equipment maintenance and maintenance It is also very necessary to know the quality of the sensors in the system and the status logs of the acquisition system operation, but the acquisition systems generall...
