Embedded-Linux-system-based automatic monitoring device and method for wireless local area network (WLAN)

Abstract

The invention relates to an embedded-Linux-system-based automatic monitoring device and an embedded-Linux-system-based automatic monitoring method for a wireless local area network (WLAN). The device comprises a power management unit, a microprocessor unit, a storage unit, a standby battery unit, a real-time clock unit, a general packet radio service (GPRS) wireless module, a WLAN module, a universal serial bus (USB) interface unit and a serial port unit. The software system structure of the device comprises a bootstrap loader module layer, an embedded Linux system kernel module layer, a driver module layer and an application program module layer. The device and the method have the advantages that: the device automatically finishes various test items, and also finishes alarming indication for overrange wireless network quality parameters of the WLAN; the internal GPRS wireless module of the device reports alarming needs and data to an encryption server platform by a transmission control protocol (TCP) / Internet protocol (IP) and a short message, a server is connected with the Internet, and a client can configure the basic information of the device by a web browser and view test results and alarming items of a certain test site only after being connected with the Internet; and the low-cost automatic monitoring device for the WLAN is provided for the stationing testing of a telecommunication operator.

Description

technical field [0001] The invention relates to a WLAN network test technology in the field of wireless communication test, and mainly relates to a WLAN network automatic monitoring device and method based on an embedded Linux system. Background technique [0002] Wireless Local Area Networks (Wireless Local Area Networks; WLAN) is a very convenient data transmission system, which uses radio frequency (Radio Frequency; RF) technology to replace the local area network formed by the old-fashioned twisted-pair copper wires (Coaxial), making wireless The LAN can use a simple access structure to allow users to achieve the ideal state of "portable information and convenient access to the world". Overview of WLAN topology: WLAN based on IEEE802.11bgn standard allows wireless connection using unlicensed 2.4 or 5.3GHz radio frequency bands in a LAN environment. [0003] GPRS--the abbreviation of General Packet Radio Service (General Packet Radio Service), it is a mobile data service...

Problems solved by technology

The known monitoring method is to use a WLAN special test instrument or run a special test software on a notebook computer with a wireless network card inserted; for various tests such as wireless coverage signal strength test, signal-to-noise ratio test, etc. Run special test software on a laptop with a wireless network card, and perform a coverage level test in the design target coverage area; due to the high price of WLAN-specific test instruments, the laptop with a wireless network card is more random, and there are many human factors , It is easy to cause incorrect test results; these are all manual tests, if the test range is large, it will take a lot of manpower and material resources, which is what the managers do not want to see
