在本软件设计中,开发平台采用WindowsNT。为保证系统的实时性和可靠性,充分利用汇编语言实时功能强,而高级语言运算能力强的优点,采用MSVB5.0和8088汇编语言混合编程方式。汇编语言执行速度快,且能有效地控制硬件,因此,采用汇编语言子程序来完成数据采集、通信等工作。利用高级语言来完成上位机的数据处理、显示、打印等工作。

整个软件系统由四部分组成,即网络初始化程序,数据采集程序,数据通信程序,数据处理与管理程序,各子程序采用模块化设计。
3.1 网络初始化程序
网络初始化程序对网络进行初始化,设置网络、网卡(通信适配卡)和采集前端机的工作方式,确定网卡是否允许越限中断,是否允许事件中断,是否自动查询前端,选择网络工作方式:循环或主从方式。给各主机的工作方式:只听或听讲。对闪端采集机的工作模式、采样周期、通道个数等进行设定。
3.2 数据采集程序
数据采集程序用于现场采样,装配在采集站中。生产过程的信号有模拟量和数字量两类。数字量包括开关量和脉冲量二种。开关量有扫描型和中断型之分。对不同的实时检测点设计成相应的数据采集软件,分别完成从相关设备采集相关的数据,进行预处理以组织成供通信软件传送的格式。
3.3 数据通信参数
数据通信程序由数据发送模块和接收模块构成。它实际上是单片机之间的(通信适配卡与采集站都是以单片机为核心构成的)通信。通信适配卡发送上位机对采集站的命令;接收采集站的实时数据,供上位机调用。
