Description: 本系统以单片机为核心，通过步进电机实现运动轨迹控制。系统由电机驱动器、黑白线检测、人机交互以及单片机控制器四个部分组成。系统中使用了两个单片机，一片为W78E58B，通过精确算法实现对步进电机的直接控制；另一片为AT89C51，用于语音播放，两单片机之间通过485通信建立联系。此外，看门狗DS1232的应用，提高了单片机控制系统的抗干扰能力。-The system to single-chip microcomputer as the core, through the stepper motor to achieve trajectory control. System consists of motor drives, black and white line detection, human-computer interaction as well as four single-chip controller parts. System using two single-chip, one for W78E58B, through accurate algorithm to realize the direct control of stepper motor another piece for the AT89C51, for voice playback, two single-chip 485 communication between the networking. In addition, the DS1232 watchdog applications, improve the single-chip control system anti-interference ability.

Description: Modbus协议最初由Modicon公司开发出来，在1979年末该公司成为施耐德自动化(Schneider Automation)部门的一部分，现在Modbus已经是工业领域全球最流行的协议。此协议支持传统的RS-232、RS-422、RS-485和以太网设备。许多工业设备，包括PLC，DCS，智能仪表等都在使用Modbus协议作为他们之间的通讯标准。有了它，不同厂商生产的控制设备可以连成工业网络，进行集中监控。-Modicon Modbus protocol originally developed by the out at the end of 1979 it became the Schneider Automation (Schneider Automation) department as part of Modbus is now the world' s most popular industrial protocol. The protocol supports a traditional RS-232, RS-422, RS-485 and Ethernet devices. Many industrial equipment, including PLC, DCS, intelligent instruments and so on using the Modbus protocol as standard for communication between them. With it, different manufacturers of industrial control equipment can be connected into the network, centralized control.
