MS-DOS平台下数据远程无线传输功能的设计

Design of Remote Wireless Data Transmission Function Under MS-DOS Platform

目前,在工业仪器仪表领域仍有不少设备使用的是MS-DOS平台。为了使得这些仪器仪表具有数据远程无线传输功能,设计了基于GPRS网络的彩信模块,通过该模块可以使得现有仪器仪表的检测数据实时地上传至远端的数据中心。首先,根据彩信模块的特点及其工作原理设计了硬件电路,然后针对MS-DOS平台下硬件设备操作的特点给出硬件驱动代码,最后给出整个系统的设计流程以及设计完成的图形界面。

At present,many devices in the industrial instrument field still use MSDOS platform.In order to make these instruments have remote wireless data transmission function.MMS module is designed based on GPRS network;this module can make the instruments transmit the testing data to the data center in time.According to the MMS module claracteristics and working principle,the hardware circuit is designed,and then hardware driver code is provided for the MSDOS platform.Fi nally the system design process and the graphical interface are showed.
