Description

Technical Field

[0001] The invention belongs to the technical field of motor protection, and in particular relates to a debugging method for a motor debugging protection device. Background Art

[0002] In applications where high-current power motors are used, the motors themselves are of great value, so their operating environment and status require real-time monitoring and protection. Detection of phase sequence errors, phase failure, three-phase imbalance, overheating, etc. requires monitoring of the motor's operating environment and status to prevent the motor from burning out. When debugging or upgrading the motor main control circuit board in the traditional way, it is usually necessary to manually set and input parameters. When the debugging parameters are inappropriate, the debugging fails, and the memory needs to be removed from the main control board, and the memory needs to be replaced or the main control board needs to be directly replaced. Traditional debugging and upgrading methods do not meet the fast-paced production requirements of automated equipment. Summary of the invention

[0003] In view of the above technical problems, the present invention proposes a debugging method for a motor debugging protection device, the device comprising a main control circuit board, a sampling circuit connected to the main control circuit board, a first storage module arranged on the main control circuit board; and a second storage module for storing spare calibration parameters;

[0004] The first sampling circuit samples from a standard current source, and the second sampling circuit samples from a motor power output terminal; the current and voltage signals collected by the sampling circuits are filtered and amplified and then output to the first storage module for storage;

[0005] The main control circuit board carries: a control module and a calibration module, the calibration module communicates with the debugging interface of the control module, and the calibration module communicates with the first storage module;

[0006] When the motor debugging program is started, the calibration module obtains standard current source data to perform an oscilloscope test step; the calibration module calls the calibration parameters of the first storage module and performs a calibration step on the motor.

[0007] The technical solution of the present invention can effectively solve the problem of debugging the motor operating state parameters based on a standard voltage source without replacing the circuit board, thereby protecting the motor from working under a safe and stable power supply.

[0012] The first sampling circuit samples from a standard current source, and the second sampling circuit samples from a motor power output terminal; the current and voltage signals collected by the sampling circuits are filtered and amplified and then output to the first storage module for storage;

[0013] The main control circuit board carries: a control module and a calibration module, the calibration module communicates with the debugging interface of the control module, and the calibration module communicates with the first storage module;

[0014] When the motor debugging program is started, the calibration module obtains standard current source data to perform an oscilloscope test step; the calibration module calls the calibration parameters of the first storage module and performs a calibration step on the motor.

[0015] The current and voltage signals collected by the first or second sampling circuit include three-phase voltage waveform data and three-phase current waveform data in time sequence, and the calibration parameters include inertia ratio, automatic gain parameters, and driver parameters.

[0016] In some solutions, the control module is provided with a selection module; if the calibration procedure fails, the selection module is activated to call the backup calibration parameters from the second storage module to calibrate the motor.

[0017] In some solutions, a data channel is provided between the first storage module and the second storage module, and the second storage module communicates with the calibration module indirectly by transferring data to the first storage module.

[0018] In some embodiments, the calibration step specifically includes: Figure 2 The following steps:

[0019] S1 sets motor parameters using the calibration parameters;

[0020] S2 obtains the standard source signal, compares the standard power supply signal with the voltage and current signal of the motor power output terminal, calculates the difference and inputs the difference into the control module;

[0021] S3, the controller adjusts the motor parameters and controls the difference through an automatic parameter adjustment algorithm, and outputs calibrated voltage and current values ​​and motor parameters;

The method includes the following steps: inputting the updated calibration parameters into the second storage module, and synchronously transmitting them to the first storage module through the data channel.

[0032] The technical effect of this invention is described below by a specific embodiment.

[0033] Example 1

[0034] During the debugging of the prototype, the voltage sampling was inaccurate. When the standard source outputted 380V line voltage, the screen displayed Uab, Ubc, and Uca were 464.9V, 413.9V, and 441.5V respectively. The screen voltage of the old main control board was normal, and the screen displayed Uab, Ubc, and Uca were 383.6V, 383.4V, and 383.5V respectively.

[0035] Remove the second E2ROM chip on the old board, output the voltage with the standard source, and power on again. The screen displayed voltage is consistent with that of the new board. After installing the removed second E2ROM chip on the new board and communicating with the controller, the screen displayed voltage is normal, all at 383.5V.
