Embodiment Construction

[0079] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are part of the embodiments of the application, not all of them.

[0080] The present application proposes a decoding redundancy system 100. The decoding redundancy system 100 can be used in a motor controller 1, and the motor controller 1 is used to control a motor. Since the angle signal of the rotor of the motor is an important input parameter of the motor controller 1, the sensor 50 is a necessary device for obtaining the angle signal in the motor controller 1, and the sensor 50 needs to use a dedicated decoding chip in order to obtain the angle signal.

[0081] Such as figure 1 As shown, the decoding redundancy system 100 includes a microprocessor 10 , a second conditioning circuit 32 , a fourth conditioning circuit 34 , a multiplexer 40 and a sens...

Abstract

The invention provides a decoding redundancy system which is applied to a motor controller, the decoding redundancy system comprises a microprocessor, a conversion unit and a sensor, and the microprocessor is electrically connected with the sensor through a second conditioning circuit; the microprocessor is used for generating an excitation signal; the sensor is used for receiving the excitation signal generated by the microprocessor and outputting a feedback signal; the conversion unit is used for converting a feedback signal output by the sensor into a digital quantity; and the microprocessor decodes the feedback signal output by the sensor according to the digital quantity converted by the conversion unit. The invention further provides a decoding method which is applied to a decoding redundancy system. The invention further provides a computer readable storage medium. The computer readable storage medium comprises a computer program and a decoding method executed by the computer program in the decoding redundancy system.

Description

technical field [0001] The present application relates to the technical field of software decoding, and in particular to a decoding redundancy system, a decoding method and a computer-readable storage medium. Background technique [0002] In the field of motor control, the angle signal of the rotor of the motor is an important input parameter for motor control. Due to the advantages of low environmental requirements and strong anti-interference ability of the input signal, the sensor has been widely used, especially in the field of new energy transportation. In order to obtain the angle signal of the sensor, it is necessary to use a dedicated hardware chip for decoding. During use, various environmental factors may cause hardware chip damage and failure, affecting the security of the system. Contents of the invention [0003] This application proposes a decoding redundancy system, which is applied to motor controllers. The decoding redundancy system includes a microproce...
