摘　　要：为了在不同的国产化中央处理器(CPU)上应用Modbus/TCP协议,需设计并实现跨平台协议库函数。根据Modbus应用协议规格说明书,在不依赖操作系统调用的前提下,对Modbus/TCP协议需支持的十大功能码进行跨平台库函数开发。库函数可被通讯应用层根据自身需求用于Modbus/TCP协议客户端和服务器端的设计和开发。经过在国产化CPU和嵌入式平台上进行二次开发,开发者调用本研究中的库函数能有效实现通过Modbus/TCP协议对反应堆冷却剂系统的稳压器压力水位及棒控棒位系统的功率调节进行数据采集。In order to apply Modbus/TCP protocol in different localized CPUs,it is necessary to design and realize cross-platform protocol library functions.According to the specification of Modbus application protocol,the cross-platform library functions of the ten function codes that Modbus/TCP protocol needs to support are developed without relying on operating system calls.The library functions can be used by the communication application layer for the design and development of Modbus/TCP protocol client and server according to its own needs.After secondary development on localized CPU and embedded platform,by calling the library function in this study,the developer can effectively collect the data of the pressurizer pressure and water level of the reactor coolant system and the power regulation of the rod control system through the Modbus/TCP protocol.
