Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing.

[0026] In the fields of CNC machine tools, robotics and servo control technology, detection units for position control, speed control or angle control systems are indispensable components. A variety of encoders and resolvers are used to detect the position, speed, and angle signals of different actuators. The invention is a signal processing device with interfaces compatible with various encoders and rotary transformers. The device can process signals from more than one encoder and resolver at the same time. The signal processing device structure compatible with various encoders and resolver interfaces is as follows: figure 1As shown, the signal processing device at least includes a signal input interface module 1, a signal conditioning circuit module 2, an FPGA circuit module 3, and a signal output interface module 4; the signal input interface module 1 includes at least...

Abstract

The invention discloses a signal processing device compatible with multiple kinds of interfaces of encoders and rotary transformers. The signal processing device at least comprises an input interface module, a signal conditioning circuit, an FPGA (Field Programmable Gate Array) circuit module and a signal output interface module, wherein the input interface module, the signal conditioning circuit, the FPGA circuit module and the signal output interface module are sequentially connected. The signal processing device can be compatible with all kinds of traditional incremental encoders, absolute type encoders and rotary transformers in the market. The invention can realize that signals of more than one encoder and rotary transformer can be simultaneously processed and one or more signal processing results are output without replacing the signal processing device of a detection element interface, is suitable for detection and processing of position, speed and angle signals of different types of mechanical movement parts, is convenient for filed debugging of technicians, is convenient for use, is good in practicability, and has better actual application value and market competitiveness.

Description

technical field [0001] The invention relates to the fields of numerically controlled machine tools, robots and servo control technology, and is especially suitable for a compatible interface signal processing device for various encoders and rotary transformers used to detect the position, speed and angle signals of different actuators. Background technique [0002] In the fields of CNC machine tools, robots and servo control technology, the detection unit of the position control, speed control or angle control system is an indispensable part, and the detected position, speed or angle information is used as the feedback signal of the closed-loop control to improve The movement speed, precision and efficiency of the equipment. [0003] At present, the detection unit of the position control, speed control or angle control system on the market mainly uses the following three components: incremental encoder, absolute encoder and resolver. Incremental encoders are small in size, ...
