Automatic identification and unified protocol device of serial encoder

Abstract

The invention discloses a serial encoder automatic identification and protocol unification device, and belongs to the field of servo motor control. The serial encoder automatic identification and protocol unification device comprises a protocol scheduling control module, multiple serial encoder protocol interfaces and a general interface conversion module. The protocol scheduling control module is respectively connected with the multiple serial encoder protocol interfaces for communication. All the serial encoder protocol interfaces can be scheduled by the protocol scheduling control module respectively. The protocol scheduling control module is connected in parallel with a serial encoder interface. The multiple serial encoder protocol interfaces are connected with the general interface conversion module for communication. The type of an encoder can be automatically identified by adopting a servo driver so that the servo driver is enabled to be matched with the corresponding serial encoder in rapid, real-time and high-efficiency manners, control efficiency of the servo motor is greatly enhanced and waste of resources is avoided; and software developers only require to know one set of parallel access interface protocols rather than protocols of a wide range of various serial encoders to perform software protocol simulation work so that the burden of development is reduced.

Description

technical field [0001] The invention relates to an identification device for an encoder, specifically an automatic identification and unified protocol device for a serial encoder, which belongs to the field of servo motor control. Background technique [0002] At present, in the servo motor control process, different types of servo drivers are used according to the motors of different types of serial encoders, so as to adapt to the analysis of various protocols of different encoders. This causes servo driver manufacturers and customers to know the encoder model of the motor before using the servo driver and the manufacturer's motor, and then set the encoder model of the corresponding motor on the servo driver before using the servo driver and the motor as a whole. , to identify the use. What's more, the same servo drive needs to be programmed with different software programs for motors corresponding to different types of encoders. That is: the same physical structure, but ...

Problems solved by technology

However, in the actual use process, even though programmable logic devices such as FPGA / CPLD help realize some interface conversions, due to differences in the protocols of encoder manufacturers, the access interfaces with processors such as CPU / DSP are still different in the end. Therefore, both software developers and hardware FPGA / CPLD developers must firmly grasp the protocols of various encoders in order to "cooperate" in their work.

[0004] The above deficiencies bring a lot of inconvenience to servo motor control, reduce control efficiency, increase the burden on developers and cause unnecessary waste of resources
