针对某型船载测控系统中遥控设备存在遥控小环比对误码故障,在分析遥控小环接收解调机理基础上,通过模拟仿真和试验研究,建立了遥控副载波收发相位延迟与数据解调间的关系模型,提出了解决遥控小环设备误码问题的设计方案。试验结果表明,该方案对于解决船载测控系统中遥控小环比对误码问题是有效的、可靠的,降低了遥控指令小环比对错误的虚、漏概率,确保了遥控指令发送状态信息的实时监视。
Aiming at the error code error of the remote control small ring in the remote control equipment of a shipborne measurement and control system, based on the analysis of the receiving demodulation mechanism of the remote control small loop, the phase delay and data demodulation of the remote subcarrier receiving and sending are established through the simulation and experimental research. The model of the relationship between the proposed remote small ring device error code design. The experimental results show that this scheme is effective and reliable for solving the problem of bit error ratio of remote control small loop in shipboard measurement and control system, and reduces the false and miss probability of remote control command small loop misalignment and ensures the real-time Surveillance.
