What are the common software problems and solutions for series excitation motor motor stator automatic slotting paper machine?
First, the software program logic error
(A) fault phenomenon
Slot paper insertion process disorder
The order of slot paper insertion does not conform to the preset, for example, slot paper should be inserted into adjacent stator slots sequentially, but there may be some slots skipped or the same slot inserted repeatedly, resulting in uneven distribution of stator slot paper and affecting motor performance.
Uncoordinated equipment movement
There is a problem with the coordination between the slot transfer and insertion motions. For example, the insertion action starts before the slot paper has completely stopped transmission, or the transmission mechanism does not respond to subsequent commands in a timely manner after the insertion is completed, resulting in a reduction in the operating efficiency of the equipment, and may even damage the slot paper or equipment components.
(ii) Cause analysis
Programming errors
In the process of software development, the actions performed by the device may not meet expectations due to errors in code writing, such as errors in conditional judgment statements and chaotic loop logic.
Compatibility problem after software update
When the software is updated, there may be incompatibility between the new program code and the old device hardware or other related software modules. For example, the updated software changes the way the sensor signals are read, and the response time of the hardware sensor is not adjusted accordingly, which can cause confusion in the program logic.
(iii) Solution
Program code checking and correction
Through software debugging tools, the control program is checked step by step. Breakpoints can be set to observe the variable values and execution paths of the program at key steps to find out the location of logical errors. For example, check the code segment that controls the slot paper insertion order to see if there is a conditional judgment error that causes the insertion order to be disordered.
Based on the results of the inspection, the erroneous code is corrected. After the code is corrected, conduct adequate testing, including simulation of various normal and abnormal operating scenarios, to ensure that the program logic is correct and that the equipment is able to perform slot paper insertion operations in accordance with the expected process.
Compatibility testing and adjustment
Perform full compatibility testing before software updates. In the test environment, run the updated software and the original hardware equipment and other related software at the same time to check whether there is any incompatibility.
If incompatibility problems are found, make adjustments to the software. This may involve modifying the software interface, adjusting the way data are read and processed, etc., to ensure that the software works in harmony with the hardware and other software. For example, if the updated software on the sensor signal reading speed becomes faster, the appropriate adjustment of the hardware sensor filtering parameters, so that the signal can better match the requirements of the software.
Second, the software parameter setting error
(A) fault phenomenon
Slot paper insertion depth or position inaccuracy
Due to the slot paper insertion depth or position related software parameters are set incorrectly, resulting in the slot paper insertion depth is too shallow or too deep, or the insertion position deviates from the center of the stator slot, affecting the quality of the motor.
Abnormal transfer speed
Improper setting of software parameters for slot paper transfer speed may make the transfer speed too fast or too slow. Too fast will lead to inaccurate positioning of the slot paper, while too slow will reduce the efficiency of the equipment.
(ii) Cause analysis
Parameter input error
Operators in the equipment commissioning or parameter adjustment process, may accidentally enter the wrong value. For example, the slot paper insertion depth parameter is set to a value beyond the reasonable range, or the transfer speed parameter is set too high or too low.
Parameter unit mismatch
In the software, different parameters may have different unit settings. If the operator does not pay attention to the unit when setting the parameters, it may lead to the actual setting of the parameters does not match with the expected. For example, mistakenly setting the unit of slot paper insertion depth from millimeters to centimeters will make the insertion depth much higher than expected.
(iii) Solution
Parameter checking and correction
First, carefully check the parameter settings in the software related to slot paper insertion depth, position and transfer speed. You can refer to the device's operating manual to determine the correct parameter range and default values.
Based on the checking results, correct the wrong parameters to the correct values. After correcting the parameters, perform a device test to observe whether the depth, position and transfer speed of slot paper insertion return to normal.
Unit Unification and Tip Setting
In the software interface, the unit of each parameter is clearly defined, and the unit conversion function is provided (if necessary). For example, next to the slot paper insertion depth parameter displays the unit as “mm”, and when the operator enters a value that does not meet the unit specification, the software pops up a prompt box to remind the operator to pay attention to the unit setting.
Limit the setting of important parameters, such as setting the upper and lower limits of the parameters, to prevent the operator from inputting values beyond the reasonable range. At the same time, the default parameter values are provided as a reference to facilitate the operator to set the parameters correctly.
III. Software Operation Stability Problems
(I) Failure phenomenon
Software crash or crash
During the operation of the equipment, the software suddenly stops working, the interface is unresponsive, and the equipment stops running. This may cause the ongoing slot paper insertion operation to be interrupted, affecting productivity, and may damage the stator and slot paper that have not finished processing.
Slowdown in operation
The response time of the software operation becomes longer, e.g. when the operator clicks an operation button, it takes longer for the machine to perform the corresponding action. This reduces the efficiency of the equipment and may affect the real-time control performance of the equipment.
(ii) Cause analysis
Memory leakage or excessive resource utilization
If there is a memory leakage problem during the operation of the software, it will cause the system memory to be occupied continuously, exhausting the memory resources behind and crashing the software. In addition, the software may process too many tasks or data at the same time, resulting in excessive resource utilization such as CPU and slower running speed.
Software conflict or virus infection
Other software installed on the device may conflict with the slot machine control software, such as when the two software compete for system resources or have conflicting access to the same hardware devices. In addition, computer viruses may infect the control software and disrupt its normal operation.
(iii) Solutions
Optimize software code and resource management
Examine the software code to find the parts that may cause memory leakage. For example, check the code for dynamic memory allocation and release to ensure that the memory is properly freed. Professional memory inspection tools can be used to help find and solve memory leaks.
Optimize the software's resource management and allocate CPU, memory and other resources reasonably. For example, for some non-critical background tasks, you can lower their priority or set them to be executed at regular intervals to avoid them competing for resources with critical device control tasks.
Software Conflict Detection and Virus Checking
When software conflicts are suspected, close other software installed on the device one by one and observe the operation of the control software. In this way, identify other software that conflicts with the control software, and consider uninstalling the conflicting software or contacting the software vendor to resolve the conflict.
Install reliable antivirus software on the device, and regularly check the device for viruses. If virus infection is found, use the antivirus software to clear the virus and repair or reinstall the software to ensure the stability of the software.
