简易微型控制器的开发

Development of simple controller device

微型控制器主要应用于中小型工业设备的控制场所,以单片机为控制芯片,实现简单开关量的逻辑运算、定时及计数功能,并利用VB6.0编制PC机执行程序编辑、编译及下载软件。微型控制器为了达到简化编程的目的,采用易于理解的类PLC指令系统编制执行程序,同时利用PC机中的编译软件对执行程序进行编译,生成二进制程序代码。主控模块通过RS232串行口与PC机进行串行通信,接收PC机编译生成的程序代码,利用单片机芯片的IAP操作模式,将接收到的程序代码下载到程序存储区,实现控制器执行程序的在线编辑、编译和下载功能,使其更便于用在中小型工业设备的控制中。

Simple controller device is mainly used in small and medium industrial equipment control sites.With SCM as the controller chip,simple controller device can realize the simple logic operations,timing and counting functions.Using VB6.0 to edit,compile and download software in PC.In order to simplify programming,the executive program is compiled with the similar PLC commands,and the executive program is translated with compile software to generate binary code.The major control module communicates with the PC by RS232 serial interface to receive the program codes compiled by PC,and with the IAP mode of SCM to download the program codes to the ROM to realize the simple controller device＇s executive program edited,compiled and downloaded online,makes it easier to be used in small and medium industrial equipment control sites.
