Description

Technical Field

[0001] The present application relates to the field of motor control technology, and in particular to a signal processing method, device, electronic device and computer-readable storage medium based on a motor controller. Background Art

[0002] The signal processing method of the motor controller is applicable to the situation where the database is changed during the vehicle development process. When the database is changed, the signal interface must be changed.

[0003] However, since the processing logic of each signal interface is different, every time a change is made in the database, it is necessary to rebuild the model or manually modify the previous model before the signal can be processed again. This leads to an increasing error rate, and the program is cumbersome and cannot adapt to high-frequency signal interface changes. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a signal processing method, device, electronic device and computer-readable storage medium based on a motor controller, so that the motor controller can realize automatic processing of signals without changing the signal interface, thereby improving development efficiency.

[0005] In a first aspect, an embodiment of the present application provides a signal processing method based on a motor controller, the method comprising:

[0027] Obtaining a resolution range value of the initial input signal;

[0028] Determining whether the initial input signal is an invalid value signal according to the analytical range value;

[0029] If so, output the invalid flag signal.

[0030] In the above implementation process, the initial input signal is judged according to the resolution range value of the initial input signal. If it is an invalid value signal, an invalid flag signal is output to ensure that the obtained signals are all invalid flag signals, which is convenient for subsequent processing.

At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0057] The specific implementation methods of the present application are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but are not intended to limit the scope of the present application.

[0058] Embodiment 1

[0059] Figure 1 is a flow chart of a signal processing method based on a motor controller provided in an embodiment of the present application, such as Figure 1 As shown, the method includes:

[0060] S1, distinguishing and processing the signal of the motor controller to obtain an initial input signal and an initial output signal;

[0061] S2, generating a data dictionary according to the initial input signal and the initial output signal;

[0062] S3, linking the initial input signal and the initial output signal with the data dictionary to obtain a peripheral input signal and a peripheral output signal;

[0063] S4, analyzing the peripheral input signal to obtain the target input signal;

[0064] S5, converting the peripheral output signal to obtain the target output signal.

[0065] In the above implementation process, the signal of the motor controller is a control signal, and it can be distinguished to obtain an initial input signal and an initial output signal, and then the initial input signal and the initial output signal are processed respectively to obtain a target input signal and a target output signal, so that the signals of the motor controller can be processed reasonably and effectively without changing the signal interface, saving time and improving development efficiency.

[0066] Taking this embodiment as an example, the signal processing method can be implemented by writing an automated script based on Matlab software, and used for automatic modeling software to realize automated signal processing, so that when the motor controller signal changes, an automated method can be used to complete the signal processing, that is, there is no need to change due to interface changes, and it can avoid the error-prone and tedious problems of manual modification, thereby improving development efficiency.

[0067] In one possible implementation, S2 includes:

[0068] Obtaining a signal table according to an initial input signal and an initial output signal;

[0069] Generate a data dictionary from a signal table.

[0070] In the above implementation process, a table and a data dictionary are generated according to the initial input signal and the initial output signal, so that the information of the initial input signal and the initial output signal can be completely recorded to avoid errors.

[0071] The signal table records various information such as the signal type, maximum value, minimum value, etc. of the initial input signal and the initial output signal, which is used to facilitate the search and comparison of the information of the initial input signal and the initial output signal when an abnormality or error occurs.

[0072] In one possible implementation, in S3, the data dictionary records the logical relationship, format and other information necessary for processing the initial output signal and the initial input signal, and the initial input signal and the initial output signal are linked to the data dictionary respectively, that is, the logical relationship, format and other information in the initial input signal and the initial output signal are compared with those in the data dictionary. If they are inconsistent, they need to be changed, and finally the peripheral input signal and the peripheral output signal are obtained. The logical relationship, format and other information of the initial output signal and the initial input signal must be consistent with that in the data dictionary before subsequent parsing or conversion processing can be performed. If the logical relationship, format and other information in the initial output signal and the initial input signal are inconsistent with those in the data dictionary, the target input signal and the target output signal cannot be output.

[0073] In one possible implementation, S4 includes:

[0074] Performing resolution analysis on the initial input signal to obtain a resolution signal;

[0075] Perform invalid value processing on the initial input signal to obtain an invalid flag signal;

[0076] Perform type conversion on the parsing signal and the invalid flag signal to obtain the target input signal.

[0077] In the above implementation process, after the initial input signal is subjected to resolution analysis and invalid value processing, the obtained analysis signal and invalid flag signal are subjected to type conversion processing to obtain the target input signal, so that the type and resolution of the target input signal can be reasonably and effectively processed.

[0078] The process of parsing the initial input signal can be divided into three parts, namely, parsing and replacing the initial input signal, invalid value processing and type conversion. When the initial input signal is input, it will be parsed and replaced, and invalid value processing will be performed in parallel, and then the target input signal will be obtained based on the obtained parsing signal and invalid flag signal.

[0079] In a possible implementation, the step of performing resolution analysis on the initial input signal to obtain a resolution signal includes:

[0080] Determine whether the signal type of the initial input signal is unsigned integer data;

[0081] If so, output the analytical signal;

[0082] If not, the initial input signal is subjected to signal conversion processing to obtain an analytical signal.

[0083] In the above implementation process, the signal type of the initial input signal is determined, and then the initial input signal whose signal type is non-unsigned integer data is converted and processed to obtain a parsed signal, which can correctly parse the initial input signal and ensure the accuracy of the initial input signal.

[0084] Exemplarily, if the signal type of the initial input signals VCU_SignalA and VCU_SignalB is unsigned integer data, they can be directly output as parsed signals; if the signal type of the initial input signal VCU_SignalC is non-unsigned integer data, it is necessary to first perform data type conversion processing, and then multiply the non-unsigned integer data corresponding to VCU_SignalC by the resolution and then add the offset to output, so as to obtain the parsed signal. For example, if there are special requirements for the initial input signal, a substitute value can be used for output, and the substitute value must ensure that the same data type as the initial input signal is maintained, such as the substitute value ic_VCU_SignalBMan_C and the data type of VCU_SignalB must be consistent, for example, non-unsigned integer data, and the data type of its substitute value ic_VCU_SignalCMan_C is set to non-unsigned integer data. Since the input data type is usually unsigned integer, it needs to be converted, that is, converted to non-unsigned integer data, and then multiplied by the resolution plus the offset to obtain the parsed signal.

[0085] In a possible implementation, the step of performing invalid value processing on the initial input signal to obtain an invalid flag signal includes:

[0086] Get the resolution range value of the initial input signal;

[0087] Determine whether the initial input signal is an invalid value signal according to the analytical range value;

[0088] If so, output an invalid flag signal.

[0089] In the above implementation process, the initial input signal is judged according to the resolution range value of the initial input signal. If it is an invalid value signal, an invalid flag signal is output to ensure that the obtained signals are all invalid flag signals, which is convenient for subsequent processing.

[0090] If the resolution range value of the initial input signal exceeds the resolution range, it is determined to be an invalid value and an invalid flag signal is output. Exemplarily, the resolution range value of the initial input signal is compared with the maximum value and the minimum value of the resolution range. If it is greater than the maximum value or less than the minimum value, the invalid flag corresponding to the initial input signal is 1. The maximum value and the minimum value of the resolution range can be calculated by the offset and the resolution of the initial input signal.

[0091] After obtaining the invalid value signal, the signal line of each signal is named, such as VCU_SignalA corresponds to ic_VCU_SignalA_InvalidFlag, and VCU_SignalB corresponds to ic_VCU_SignalB_InvalidFlag.

[0092] In a possible implementation, the step of converting the peripheral output signal to obtain the target output signal includes:

[0093] Get the signal type of the peripheral output signal;

[0094] If the signal type of the peripheral output signal is non-unsigned integer data, the peripheral output signal is converted to obtain a target output signal.

[0095] In the above implementation process, the type of the peripheral output signal is converted according to the signal type, so that the type of the target output signal can be unified, thereby avoiding the inability to output due to different types of target output signals.

[0096] When identifying the peripheral output signal, the same frame message can be classified and processed, and it can be determined whether the signal type is unsigned integer data. If it is unsigned integer data, the target output signal can be directly output after conversion. If it is identified as non-unsigned integer data, the non-unsigned integer data is subtracted from the offset and divided by the resolution to output the target output signal.
