Description

WiFi MAC address remote acquisition system based on LoRa

Technical Field

The utility model relates to a MAC address acquisition field, in particular to wiFi MAC address remote acquisition system based on loRa.

Background

WiFi technology is a very popular wireless communication technology, and the wireless frequency band used by the technology is the ISM band (the unlicensed and paid frequency band defined by the international communications union). In the mobile phones and intelligent terminals of the present day, WiFi modules have become standard, and each WiFi module is assigned a globally unique MAC address, which can be used to identify a device. Mac (media Access Control address) to be translated into a media Access Control address. The MAC address is 48 bits in length, 6 bytes, and is typically represented by 12 16-ary numbers, with an or separation between each two numbers, such as: FF is FF, and FF is FF. The wireless signals of WiFi communication are transmitted in the air, data packets transmitted in the air can be monitored through corresponding hardware and software tools, MAC addresses of intelligent equipment such as a mobile phone can be obtained after the data packets are analyzed, and the wireless signals can be used in the application fields of information security, passenger flow statistics, market hotspot area analysis, attendance checking and the like.

The data transmission after the MAC address is collected in the prior art has the following defects: after the MAC address data is collected, the MAC address data is transmitted to a close-range upper computer generally through Bluetooth or WiFi, or is transmitted to a back-end server through an operator network; the prior art can not meet the requirement when server-free transfer is required or data transmission at a longer distance is required in an area without an operator network.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

At the occasion that does not have operator signal coverage (like remote mountain area) or require higher to data real-time (data do not pass through the server transfer), if need carry out remote transmission with data, the utility model discloses a this kind of remote, low-power consumption transmission technology of loRa. LoRa is a low-power-consumption wide area network protocol developed by Semtech corporation, and can perform data transmission at a longer distance under very low power consumption, wherein the transmission distance can reach 2 to 5 kilometers in towns, and can reach more than 10 kilometers in suburbs. LoRa works in license-free frequency bands including 433MHz, 868 MHz, 915 MHz, 923 MHz and the like. The transmission rate of data is several tens to several hundreds of Kbps, and the lower the transmission rate, the longer the transmission distance.

In order to solve the problem of above-mentioned remote transmission, the utility model discloses introduce the loRa technique, through combining loRa module and wiFi module, solved the remote transmission problem after gathering wiFi MAC address data.

The utility model discloses an aspect provides a wiFi MAC address remote acquisition system based on loRa, include: the system comprises an acquisition end and a receiving end;

the collection end includes: the wireless fidelity (WiFi) acquisition module is used for acquiring a nearby WiFi Media Access Control (MAC) address, an LoRa transmission module used for broadcasting acquired WiFi MAC address data through an LoRa protocol, a battery used for supplying power to an acquisition end and an external antenna of the acquisition end, the WiFi acquisition module is respectively connected with the LoRa transmission module and the battery, and the LoRa transmission module is connected with the external antenna of the acquisition end;

the receiving end includes: the USB device comprises an LoRa receiving module, a USB serial port conversion module and a receiving end external antenna, wherein the LoRa receiving module is used for receiving broadcast data transmitted by the LoRa transmitting module, the USB serial port conversion module is used for converting a receiving end into a USB device, and the receiving end external antenna is connected with the LoRa receiving module.

The utility model discloses a work flow as follows: the WiFi acquisition module can acquire WiFi MAC address data within a range of about 100 meters of the radius nearby after being switched to a monitoring mode, and after the data are acquired, the data are removed from repetition and compressed, and necessary information is reserved, so that the data can be rapidly transmitted at a low speed. And after the data are processed, the data are sent out in a broadcasting mode by using an LoRa module. The receiving end equipment collects the broadcast data of the sending end through the LoRa module, then the USB-to-serial port module enables the receiving end hardware to be used as a USB device and a mobile phone end to communicate, the data are transmitted to an android mobile phone through a USB line, and the data are processed and displayed through software installed at the mobile phone end.

In the technical scheme, the utility model discloses combine wiFi collection module and loRa module together, solved in not having operator signal cover or to the higher occasion of data real-time requirement MAC address data acquisition and remote transmission's problem.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
