基于GPRS的煤炭产量监控系统数据传输可靠性设计

Reliability design of coal production monitoring and control system data transmission based on GPRS

比较分析传输层的TCP与UDP协议的传输效率与系统需求,对于本系统来说,采用UDP协议比较好,同时应用层采用用户自定义协议,在数据传输中采用"数据中加入序号字节"以及"应答确认"等机制,可以很好地保证数据传输的可靠性。

Compared the transmission layer protocol UDP with TCP in the transport efficiency and system requirement, for the single chip system, UDP is preferred in our system, meanwhile, the user-defined protocol in application layer is proposed, by adding the number byte in data frame and adopting the scheme of response to assure the reliability in data .transmission.
