摘要

本文研究了多轴3D FDM打印机等中低端机电系统的同步和无噪声信息交换问题。指出了阻碍ModBus、CAN等常用工业技术和协议使用的问题。提出了一种基于通用微控制器中已知标准接口的方法，以使其在机电系统中成功应用。以STM32F303单片机的I2C接口为例，提出了一种通过引入带纠错码的抗扰性来改进现有接口的方法，并建立了多播和仲裁机制。此外，还考虑了驱动P82B96提供光隔离的机制。

Problems of synchronous and noise immune transmission of information in intelligent mechatronic systems

This paper considers the problem of synchronous and noise free information exchange in the low-end and mid-end mechatronic systems such as multi-axis 3D FDM printers. Problems which prevents the usage of common industrial technologies and protocols such as ModBus, CAN etc. are stated. Approach based on the usage of known standard interfaces present in general-purpose microcontrollers for their successful application in mechatronic systems is proposed. As an example, a method based on modification of existing STM32F303 MCU's I2C interface by introducing additional noise immunity with corrective codes, as well as creating mechanisms for multicasting and arbitration is proposed. In addition, the mechanism for providing optical isolation with drivers P82B96 is considered.
