Embodiment Construction

[0019] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] like figure 1 As shown, a motor sensor data acquisition unit, the motor sensor data acquisition unit includes a single-chip microcomputer and a temperature acquisition module connected thereto, an ADC acquisition module, a 485 bus driver module and a storage module;

[0021] The ADC acquisition module collects the three-phase current and voltage of a single motor;

[0022] The temperature acquisition module collects the temperature of a single motor;

[0023] The ADC acquisition module also collects vibration signals on both sides of the shaft of a single machine;

[0024] After the signal is collected from a single motor, it is filtered and screened and uploaded at a certain frequency.

[0025] The motor sensor data acquisition unit uses an embedded 32-bit single-chip microcomputer as the core to collect vibration signa...

Abstract

The invention discloses a motor sensor data acquisition unit and method, and the unit comprises a single-chip microcomputer, and a temperature acquisition module, an ADC acquisition module, a 485 busdrive module and a storage module connected to the single-chip microcomputer, wherein the single-chip microcomputer starts a DSP unit, processes the temperature, voltage and current signals collected,removes periodic and sudden interference noise by a filtering algorithm, and identifies the characteristic fault of the motor by a mechanism model algorithm. When a known type is detected, the single-chip microcomputer accelerates the sampling and more accurately identifies fault information. The comprehensive collection of signals about vibration, current and temperature of the motor can determine at the acquisition end that an edge computing has been carried out, without waiting for the network host to issue a command to the bottom to execute. In the field environment where the network bandwidth is not too high, the need for data upload to the network can be reduced to improve the real-time performance of the network. The network can also be prevented from interfering with the scene tocause production accidents when the network is abnormal.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a motor sensor data acquisition unit and a data acquisition method. Background technique [0002] In the current industrial sites, the vibration, current, and temperature of the motor are rarely collected together. In some sites, only the current and temperature are collected for monitoring analysis, but they do not conduct predictive analysis on the equipment, and can only estimate Periods of equipment failure are responsible for maintenance. This will waste manpower and material resources to periodically overhaul the equipment, which is not conducive to the improvement of production efficiency. Contents of the invention [0003] In order to solve the technical problems in the background technology, the present invention provides a motor sensor data acquisition unit and a data acquisition method. The comprehensive acquisition of the vibration, current, and temperature s...
