摘要
针对传统无线传真实时方案开发周期长、难度大的问题,提出一种基于存储转发的通用无线传真接口方案.选用带有并行EPI接口的LM3S9B6和CY62157EV30作为处理器和存储器,将传真数据存储起来,这样就实现了传真机与处理器之间通信和无线模块与处理器之间通信过程的分离.同时在深入研究T.30、T.4的基础上,在此硬件设计实现了通用的、可靠地传真通信软件.通过对实际系统的运行结果分析,能有效地缩短无线传真的开发周期和降低开发难度.
To address the lengthy cycle and difficulties in developing traditional wireless fax re- al-time scheme, we propose a storage-and-forwarding-based general wireless fax interface scheme. LM3S9B6 and CY62157EV30 with parallel EPI interface are used as the processor and memory to store fax data. Thus, the communication separation between the fax machine and the processor, and the wireless module and the processor is realized. Meanwhile, based on the study of T. 30 and T. 4, the hardware design and implementation leads to the application of a universal and reliable fax communication software. An analysis of the system running shows that the scheme is effective in shortening the wireless fax development cycle and reducing the difficulties.
