Abstract

The invention relates to a universal portable remote high-power steering gear voltage and current measurement and calibration device, which comprises a power supply module, a bus communication module, a remote distance / peak current judgment module, a voltage and current range gating module, a signal conditioning / acquiring / converting / outputting module, and a principal computer test system interface module. The device has a small size and a complete range of interfaces, can be easily carried and used in all test sites, is suitable for measuring and calibrating the current and voltage of a remote to-be-tested steering gear with high peak current and rated voltage, is provided with a multi-gear measurement output range, is equipped with a variety of interface equipment, and is of high universality.

Description

technical field [0001] The invention relates to the technical field of steering gear voltage and current measurement and calibration, in particular to a universal portable remote high-power steering gear voltage and current measurement and calibration device. Background technique [0002] During the inspection process of the steering gear test, while performing the necessary test steps such as zero position, step, non-sensitive area, nonlinear area, frequency sweep, and running-in, it is also necessary to measure and feed back the voltage from the motor bus in real time, The current signal is used for system status monitoring (such as overvoltage protection, undervoltage protection, overcurrent protection, etc.). [0003] In the common steering gear test system, the test software and the steering gear model are often in one-to-one correspondence. In the face of steering gear test systems of different models and different powers, there is a lack of a generalized measurement ...
