Method and device for acquiring wireless network data

The invention discloses a method and a device for acquiring wireless network data. The method for acquiring the wireless network data is executed by data acquisition equipment associated to an access point AP and comprises steps as follows: a data acquisition command is called; a power-saving announcement message is sent to the AP according to the data acquisition command, so that the data acquisition equipment enters a data acquisition mode; in the data acquisition mode, the data acquisition equipment keeps an associated state with the AP for WIFI scanning, wireless network signals on different channels are obtained, and wireless network data are acquired according to the wireless network signals on different channels. Wireless deployment of the data acquisition equipment is realized, the data acquisition quantity is effectively increased, the system stability is effectively improved, and the deployment cost is saved.
