Vehicle-mounted mine car test data acquisition system and electric drive ore machine

Abstract

The invention discloses a vehicle-mounted mine car test data acquisition system and an electric drive ore machine, and belongs to the field of mechanical control. The vehicle-mounted mine car test data acquisition system comprises a voltage sensor 3, a current sensor 4, a voltage acquisition module 5, a current acquisition module 6, a real-time controller 7 and an upper computer 8. The voltage sensor 3 and the current sensor 4 are respectively connected with a tested object 1 and detect voltage signals of the tested object 1 and current signals of the tested object 1 respectively. The voltage acquisition module 5 and the current acquisition module 6 are connected with the voltage sensor 3 and the current sensor 4 respectively. The voltage acquisition module 5, the current acquisition module 6 and the upper computer 8 are connected with the real-time controller 7, and the real-time controller 7 is connected with the electric drive ore machine through a CAN bus and detects machine signals of the electric drive ore machine. According to the technical scheme, data acquisition is conducted by the cooperation of a data acquisition mode of the CAN bus and a data acquisition mode of a special data acquisition device, data acquisition speed and test accuracy is high, and repeatability is good.

Description

technical field [0001] The invention belongs to the field of mechanical equipment manufacturing, and relates to a test data collection system, in particular to a vehicle-mounted mine car test data collection system for electric-driven mining machines. Background technique [0002] In terms of data acquisition of automobiles, signal / data acquisition systems based on CAN bus are more common. In the prior art, some solutions of the data acquisition system based on the CAN bus are used to collect data through the CAN bus. However, these technologies have the following disadvantages in the collection of mine car test data: the signal receiving period is fixed and relatively large, which can be used to collect the signal of the whole vehicle, but cannot collect the signals in the control circuit and the drive circuit. [0003] In terms of signal acquisition, dedicated data acquisition equipment is more commonly used, suitable for high-precision acquisition and mass storage. Some...
