An information collection system, comprising: a gateway and a data platform; The gateway is used to collect the wifi packets sent by the terminal and/or the wifi packets sent by the gateway itself; extract the address field from each wifi packet, and determine the corresponding wifi packet according to the address field. type data; according to the type data corresponding to the multiple wifi packets, perform statistics on the multiple wifi packets to obtain different types of statistical data; send terminal information to the data platform, where the terminal information includes different types of statistical data; the data platform for receiving the terminal information; The terminal information further includes an address field, and the statistical data of different categories includes the amount of downlink data and the amount of uplink data; The data platform is also used to query the terminal identification corresponding to SA and TA from the database, and determine whether the inquired terminal identification is consistent with the pre-acquired terminal identification; When they are consistent, it is determined that the terminal is connected to the gateway; the rate of downlink data is calculated according to the amount of downlink data, the collection period and the average length of the downlink data; the rate of uplink data is calculated according to the amount of uplink data, the collection period and the average length of the uplink data. 8. The information collection system according to claim 7, wherein the terminal information further comprises a gateway device identification; The data platform is further configured to parse out the gateway device identification from the terminal information, and query the gateway location information corresponding to the gateway device identification from the database according to the gateway device identification.
