Abstract

The application discloses a signal processing method and device. The method comprises the following steps: deploying a Wi-Fi probe in a preset region; collecting a Wi-Fi signal of to-be-detected equipment in the preset region; computing average signal intensity of the Wi-Fi signals of the to-be-detected equipment in the setting period; determining the dynamic threshold, wherein the dynamic threshold is used as the average signal intensity at the preset processing location; and judging whether the target group enters the target place in the preset region according to the dynamic threshold value. Through the signal processing method disclosed by the application, the problem that large error is existent in a judgment result of judging whether the target group enters the target place by usingthe detection data of the unprocessed Wi-Fi probe and the experience threshold in the prior art is solved.

Description

technical field [0001] The present application relates to the communication field, and in particular, to a signal processing method and device. Background technique [0002] Wi-Fi probe technology refers to the technology based on Wi-Fi detection technology to identify smart phones or other Wi-Fi terminals that have turned on Wi-Fi near the wireless access point, without requiring users to access Wi-Fi, Wi-Fi The probe is able to identify the user's information. The data collected by the Wi-Fi probe is mainly the information of the Mac layer, such as the device Mac address, Wi-Fi signal strength, Wi-Fi signal channel, signal frame type, etc. [0003] Wi-Fi probes are often used in the field of passenger flow statistics. According to the principle that the closer the Wi-Fi terminal is to the Wi-Fi probe, the stronger the detected signal strength is. In the prior art, a signal strength threshold is artificially set. Directly compare the detected signal strength with the thre...
