摘要
基于数字通信系统中差错控制机制的基本理论,针对工业环境中干扰比较严重的情况下,提出了一种混合差错控制系统来保证工业控制网络通信的实时性和可靠性,并对其中主要的差错控制编码方法进行了数学模型研究与软件实现,最后分析了该差错控制机制的性能。实际应用结果表明该混合差错控制系统在保证一定吞吐量的同时能减少信道误码率,有效地提高了工业控制网络的通信能力。
Put forward a sort of Hybrid Error Control System to ensure the real-time and reliable transmission of data in the communication of control network,especially in view of heavy disturbance in industry environment.The math model of coding and realization of software are studied ,including the ability of decoding of the HEC system. The practical application has proved that the HEC system can decrease the bit error rate in transmission and improve the communication ability.
