WiFi data collection device based on portable power bank power supply and method thereof

Abstract

The invention provides a WiFi data collection device based on portable power bank power supply and a method thereof. The device comprises a power bank body and a WiFi data collecting device built in the power bank body, wherein the power bank body comprises a USB interface, an RJ45 internet access and a first power transmission connector assembly; the WiFi data collecting device comprises a WiFi data collector and a second power transmission connector assembly; the WiFi data collector comprises a main control module, a 3G / 4G / 5G module, a 2.4G / 5G wireless module, a wired module, a storage module and a GPS positioning module; the 3G / 4G / 5G module, the 2.4G / 5G wireless module, the wired module, the storage module and the GPS positioning module are connected onto the main control module. The method comprises the steps of positioning, packet capturing, storage and data export. The WiFi signals can be scanned along with the movement of people; the handshake packet capture can be performed; the obtained data packet is subjected to processing and analysis and can be used for assisting police law enforcement personnel to improve case solving efficiency and helping the police law enforcementpersonnel to mine and expand clue channels.

Description

technical field [0001] The invention relates to a power bank and its application, in particular to a WiFi data acquisition device and method based on a portable power bank for power supply. Background technique [0002] Charging with a power bank is becoming more and more important in modern people's life. Data show that in 2017, among the global mobile device users, there were about 1 billion charging behaviors every day, and more than 100 million charging behaviors were outside the home office. A power bank is a portable charger that integrates charging and power supply functions. It can directly power or charge mobile electronic devices such as mobile phones, tablets, and cameras through the DC power input interface. Power banks generally use lithium-ion or lithium-polymer batteries as energy storage materials, regulate the voltage through IC chips, and use the USB interface to release the stored power to charge the device through a step-down or step-up circuit. It can ...
