Test tool for motor controller

Abstract

The invention relates to a test tool for a motor controller. The test tool comprises upper computer configuration software, a main control board, an oscilloscope, a signal switching board, a probe board and a power supply unit, wherein the power supply unit comprises a high-voltage programmable power supply and a plurality of low-voltage direct-current power supplies; the main control board controls the signal switching board through a CAN bus to realize connection between the oscilloscope and the probe board; the oscilloscope and the high-voltage programmable power supply are controlled through a TCP / IP protocol; and the communication test of the motor controller is realized through a communication line. According to the invention, signal detection and communication function detection of various motor controllers can be realized through configuration of the upper computer, rapid automatic detection can be realized by separating from the upper computer during production line detection, and the test tool has the advantages of strong expansibility, good compatibility and stable control.

Description

technical field [0001] The invention belongs to the field of motor control, and in particular relates to a test tool for a motor controller. Background technique [0002] The motor controller is an integrated circuit that controls the motor to work according to the set direction, speed, angle and response time by actively working. At present, the motor controller designed and put into production has complex structure and various functions, and it is very likely to produce inferior products in the production process of the factory. Therefore, it is essential to carry out tooling inspection for newly produced motor controllers before they are put into use. [0003] At present, there is no complete, strict and multifunctional automatic detection device for mass-produced motor controllers. Most of the existing detection devices measure the voltage value of the measured signal through AD acquisition. This detection method usually only detects the voltage amplitude and the detec...

AI Technical Summary

Problems solved by technology

This detection method usually only detects the voltage amplitude and the detection result is inaccurate, and it is difficult to detect time-related signal items such as frequency and period.

At the same time, the existing detection devices also have problems such as the inability to detect the communication function of the controller and the inability to separate from the upper computer detection.
