Description
Technical field
The present invention relates to the technical field that rotation becomes decoding chip data processing, a kind of specially read in real time becomes with monitoring rotation
The method of decoding chip data.
Background technique
Rotor-position is the key input parameter of motor control.Used in new energy vehicles motor generally use rotary transformer (with
Call " rotation becomes " in the following text) obtain rotor-position.Rotary transformer needs that decoding chip is cooperated to use.What decoding chip became to generate rotation
Pumping signal, the feedback signal that parsing rotation becomes calculate angle and speed that rotation becomes, and communicate with main control chip and upload data,
However to become decoding chip data transmission longer to the MCU time for existing rotation, and then the motor control algorithms occupied time is longer,
So that the bad dynamic performance of motor control.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of method for reading and monitoring in real time rotation and become decoding chip data,
Data, the monitoring rotation change decoding chip failure that rotation becomes in decoding chip are continuously read using the ability of CPLD parallel data processing,
And it is uploaded to MCU by the data that decoding chip is read are become from rotation, location information is obtained in real time, is reduced shared by motor control algorithms
Time improves the dynamic property of motor control.
A kind of method that real-time reading becomes decoding chip data with monitoring rotation, it is characterised in that: it includes MCU, CPLD, rotation
Become decoding chip, is provided with communication module 1, data memory module, communication module 2 and control module, the rotation in the CPLD
Becoming decoding chip includes data transmission terminal, fault pin, and the communication module 1 is connected to the MCU, and the communication module 1 is used
In the communication of CPLD and MCU, the communication module 2 connects the data transmission terminal that the rotation becomes decoding chip, the communication module 2
Become the communication of decoding chip with rotation for CPLD, the data memory module difference transmitted in both directions connects the communication module 1, leads to
Believe module 2, the Data Concurrent of the data memory module caching communication module 2 is sent to communication module 1, the data memory module
The data of caching include angle, speed and the fault code indications that rotation becomes, and the control module is responsible for the data-flow-control inside CPLD
System and scheduling, the fault pin that the rotation becomes decoding chip send Reflector to the control module.
It is further characterized by:
When normal work, the communication module 2 periodically becomes decoding chip with rotation and is communicated, and reads rotation varied angle, speed
Degree, and by data buffer storage to data memory module；When breaking down, rotation becomes decoding chip and sends Reflector by fault pin
To CPLD, communication module 2 reads rotation and becomes decoding chip error code, and by data buffer storage to data memory module；
The communication of the communication module 1 and MCU uses acknowledgement mechanism, the request of data of the CPLD response MCU.
After applying the present invention, rotation is continuously read by CPLD and becomes position and speed data in decoding chip, and according to need
It asks and is uploaded to MCU, improve the rapidity that data update；CPLD real-time monitoring rotation simultaneously becomes the fault-signal of decoding chip to guarantee
The precision and accuracy of position and speed data, this method shortens the time that location information obtains, and (i.e. acquisition position is believed in real time
Breath), it is possible to reduce the motor control algorithms occupied time, improve the dynamic property of motor control.
