摘　　要：电力监控系统环境中存在过多噪声因素干扰,导致通信效率和质量低。为此,提出一种基于传输控制协议/网际协议(transmission control protocol/internet protocol,TCP/IP)与关联规则的多线程通信算法。将背景噪声看作电力监控信号的突变现象,查找回应突变函数的信号值,利用谐波分离算法,去除背景噪声。根据不同线程的传输特点,采用TCP/IP协议建立通信程序包,分别设置句柄、终止、挂起以及执行函数,为不同线程的通信数据,匹配不同的通信协议。试验结果证明:对电力监控系统源设备的传输信号多线程通信时,通信信号波频变化最为平稳,在0~2000 s的采样区间内,未出现传输为0现象;对背景噪声去噪后,波形相比原始信号变化明显较为稳定,没有出现过高或过低的幅值变化。所提方法通信信号表达平稳、效率较高,对原始信号的保留效果较好,去噪能力很强。There are too many noise factors in the environment of power monitoring system,resulting in low communication efficiency and quality.Therefore,a multithreading communication algorithm based on transmission control protocol/internet protocol(TCP/IP)and association rules was proposed.The background noise was regarded as the sudden change of power monitoring signal,the signal value in response to the sudden change function was found,and the harmonic separation algorithm was used to remove the background noise.According to the transmission characteristics of different threads,TCP/IP protocol was used to establish communication packages,and handle,terminate,suspend and execute functions were set respectively to match different communication protocols for communication data of different threads.The test results show that the wave frequency variation of the communication signal is the most stable during the multithreading communication of the transmission signal of the source equipment of the power monitoring system.In the sampling interval of 0~2000 s,the transmission is not zero;after denoising the background noise,the waveform changes more stable than the original signal,and there is no too high or too low amplitude change.The communication signal expression of the proposed method is stable,efficient,and has good retention effect on the original signal and strong noise removal ability.
