本发明涉及数据处理技术领域,提出了一种多源公路设施数据信号优化收集处理方法,包括:采集若干车流量数据及噪声数据与温度数据;根据实际采样时刻与理论采样时刻,获取每个车流量数据的第一时间偏差度及每个噪声数据的第二时间偏差度;根据相邻采样时刻的车流量数据及噪声数据,得到每个车流量数据的差异程度;根据差异程度、第一时间偏差度、第二时间偏差度及温度数据,获取每个车流量数据的异常程度;根据车流量数据的异常程度筛选发生异常的车流量数据并重新获取,实现多源公路设施数据信号的优化收集处理。本发明旨在解决公路车流量数据探测过程中受温度及噪声影响导致探测结果不准确的问题。

    The invention relates to the technical field of data processing, and provides a multi-source highway facility data signal optimization collection processing method, which comprises the following steps: collecting a plurality of traffic flow data, noise data and temperature data; acquiring a first time deviation degree of each traffic flow data and a second time deviation degree of each noise data according to the actual sampling time and the theoretical sampling time; according to the traffic flow data and the noise data at the adjacent sampling moments, the difference degree of each piece of traffic flow data is obtained; according to the difference degree, the first time deviation degree, the second time deviation degree and the temperature data, obtaining the abnormal degree of each piece of traffic flow data; and screening the abnormal traffic flow data according to the abnormal degree of the traffic flow data, and obtaining the abnormal traffic flow data again, thereby realizing optimized collection processing of the multi-source highway facility data signals. The invention aims to solve the problem that the detection result is inaccurate due to the influence of temperature and noise in the road traffic flow data detection process.
