The invention discloses a crowd remote-sensing monitoring system and a crowd remote-sensing monitoring method based on a mobile phone. The crowd remote-sensing monitoring system comprises a mobile phone signal receiving device (100) used for directionally receiving a mobile phone signal in a monitoring area, and a signal processing device (200) used for calculating the number of people and the distribution positions of people in the monitoring area according to the signal received by the mobile phone signal receiving device (100). According to the crowd remote-sensing monitoring system provided by the invention, the number of people and the distribution positions of people can be calculated based on the hardware coding and signal strength of a mobile phone signal. The calculation method is simple, high in precision, low in cost and easy to implement.
Description
technical field [0001] 本发明涉及通信技术领域,尤其涉及一种基于手机的人群遥感监测系统及方法。 Background technique [0002] 在大量人群聚集的地方,如在集会、游行、大型商场、大型活动等人流密集的区域,监测在这些特定区域的人员数量,对人员监管以及紧急情况下的人员疏散等具有重要意义。此外,在各种灾害(如地震、火灾等)发生后,快速确定灾区人数和分布位置,对灾后救援及其重要。 [0003] 现有技术中,人们也探索了很多方法来解决上述人员监测及定位的问题,如人工监测(计数),图像监测,红外监测等。然而,这些方法使用起来极不方便,技术成本较高,且误差很大。 [0004] 目前,手机已经被社会广泛采用。手机可以发射各类信号,如手机通讯信号、蓝牙信号、WIFI信号和射频信号等。然而,现有技术中,并没有利用手机的这些信号来实现对人员数量和分布位置进行精确监测的技术方案。 Contents of the invention [0005] 本发明实施例所要解决的技术问题在于,针对现有对人员数量和分布位置进行监测的技术方案使用不方便、技术成本高且误差很大的缺陷,提供一种使用方便、成本低且精确度高的基于手机的人群遥感监测系统及方法。 [0006] 本发明就上述技术问题提出以下技术方案: [0007] 本发明提供了一种基于手机的人群遥感监测系统,其特征在于,包括定向接收监测区域内的手机信号的手机信号接收装置、以及根据所述手机信号接收装置所接收的信号计算得到该监测区域的人员数量和分布位置的信号处理装置; [0008] 所述手机信号接收装置包括:用于定向接收手机信号的定向天线、用于接收所述定向天线接收到的信号并将信号解调的信号接收与解调单元、用于读取所述信号接收与解调单元解调后的信号中的硬件编码的信号硬件编码读取单元、以及用于测量所述定向天线所接收到的信号的信号强度的信号强度测量单元; [0009] 所述信号处理装置包括:用于计算在有效时间内的所述硬件编码的数量、并根据所述硬件编码的数量和所述信号强度计算监测区域内的人员数量的人员数量计算模块,用于测量所述定向天线指向发出信号的手机的方位的定向模块,以及用于根据所述信号强度计算所述手机信号接收装置到手机的距离、并根据计算的距离以及所述...
