用电信息采集系统中多源异构通信协议设计

Design of multi-source heterogeneous communication protocol in electricity utilization information acquisition system

数据采集终端中上下行数据通信遵循的通信协议不同,导致主站接收数据与电能表采集数据的质量不同,也无法保证产品的复用性。现有的面向对象协议对终端不同功能模块数据统一通信的支持还不完善,导致终端的数据采集耗时较长。因此需要设计一种支持多源异构数据的通信协议,保证终端的各功能模块能够快速、统一的进行数据通信,有效提高数据采集效率。对现有的面向对象通信DLT698.45协议进行扩展,在各个功能模块中增加了相应的属性和方法,实现对不同功能模块中多源异构数据通信的支持。实验测试中使用多源异构通信协议的终端在功能和性能上明显优于面向对象通信协议,将多源异构协议应用到终端产品中可以增强终端的各项功能支持,同时显著提高数据采集效率。

The up and down data communication of the data acquisition terminal follows different communication protocols.As a result,the quality of the data received by the main station is different from that of the data collected by electric energy meter,and the reusability of the product cannot be ensured. The current object-oriented protocol cannot well support the unified communication of data from various modules of the terminal,which results in more time for data acquisition of the terminal.Therefore,it is necessary to design a communication protocol supporting multi-source heterogeneous data to ensure all the modules of the terminal can communicate quickly and uniformly,so as to improve the efficiency of data acquisition effectively.The current object-oriented communication protocol DLT698.45 is extended. The corresponding properties and methods are added in all functional modules to realize the support of multi-source heterogeneous data communication. In the test experiment,the terminal using multi-source heterogeneous communication protocol has an obvious function and performance advantage in comparison with the one using object-oriented communication protocol. Applying the multi-source heterogeneous protocol to terminal products can enhance the function support of the terminal and significantly improve the data acquisition efficiency.
