基于VB6的PC机与多台单片机通信在锂电池检测化成设备中应用

Application of communication between PC computer and multiple singlechipsused in the control of the chargingand dischargingprocess of lithium batteries

用基于VB6的PC机通过RS485总线与多达16台PIC16F873单片机进行通信,每台PIC16F873通过I2C总线又分别挂接8台PIC16F874,其中每台PIC16F874负责16个锂电池的充放电控制,从而实现利用单台PC机对2048个锂电池的充放电控制和数据管理功能。本文给出了系统的结构原理框图,并阐明了系统的通信协议和程序设计思想。
