为了在实验室模拟工业场合,研究和解决工业现场检测和控制问题,设计了一种基于AT89C51的单片机综合实验系统.以单片机为核心,通过A/D和D/A转换模块实现模拟量的采集和控制,利用按键控制模块完成系统参数设置,利用液晶和可编程时钟等模块进行采集数据和时间等的显示,通过串行通信模块、RS232和RS485总线实现单片机与计算机的通信,通过仿真机在线编写、调试和修改单片机程序.结果表明系统能够进行多路模拟信号的采集、处理、显示、控制和远距离通信,而且采集数据正确率高、通信实时性强,控制可靠.
In order to research and solve the problem of industrial field detection and control in the laboratory simulation industrial environment, a kind of integrated experimental system based on AT89C51 is designed.Analogical acquisition is realized by A / D and D / A conversion module with the singlechip as the core And control, the use of key control module to complete the system parameter settings, the use of liquid crystal and programmable clock modules such as acquisition data and time display, through the serial communication module, RS232 and RS485 bus to achieve single-chip computer and computer communication through the simulator online The results show that the system can collect, process, display, control and remote communication of multi-channel analog signals, and the data acquisition accuracy is high, the real-time communication is strong, and the control is reliable.
