The information exchange system is based data exchange agreement to realize point, and exchange between asynchronous communication & data. 信息交换系统是基于数据交换协议(DEA)实现节点、中心之间的异步通信和数据交换的。
Research on the communication module, the types and bulk of data exchanging between modules, and then design a simple and practical data exchange agreement. 研究了模块间通讯的模型、数据交换类型和数据量,由此设计出简单、实用的数据交换协议(DEA)。
A good data exchange agreement not only better realizes data exchange system, to improve exchange efficient, reliability, safety, application system inserting, but also to be advantageous to development and escalation of data exchange system. 一个良好的数据交换协议(DEA)不但有利于数据交换系统的实现,有利于提高数据交换的效率、可靠性、安全性,有利于应用系统的接入,还有利于数据交换系统的扩展和升级。
The data exchange agreement of control board is defined in this paper, for an example, to realize the configuration interface with the table of configuration. 在软件层次上实现现场组态接口系统,本文对控制板的交换数据协议进行定义,并举例说明了上位主机建立组态表来实现可组态的接口。
There are three communication agreements designed here, which including the data exchange agreement between the principal CPU and the subordinate CPU, the agreement between the general control CPU and the touchscreen, the agreement between the principal machine and the sub-machine. 设计了三套通讯协议,包括下位机子站中主从CPU通过数据缓冲模块进行数据交换的通讯协议;主控CPU与触摸屏的通讯协议;
