Abstract

The application discloses a signal processing method and device. Deploying a Wi-Fi probe in a preset area, the method includes: collecting a Wi-Fi signal of a device to be detected in the preset area; calculating an average signal of the Wi-Fi signal of the device to be detected within a set period Intensity; determining a dynamic threshold, wherein the dynamic threshold is used as the average signal strength of a preset processing location; and judging whether the target group enters a target place within a preset area according to the dynamic threshold. The present application solves the problem in the prior art that there is a large error in the judgment result of using the unprocessed Wi-Fi probe detection data and the empirical threshold to judge whether the target group enters the target place.

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...
