Multimode network road tester based on ARM (Advanced RISC Machines) Cortex-A8 processor

Abstract

The invention relates to a multimode network road tester based on an ARM (Advanced RISC Machines) Cortex-A8 processor. The multimode network road tester comprises a tester external interface unit, a large-capacity lithium battery, a power supply management unit, an ARM Cortex-A8+DPS (Data Processing Station) dual-processor + memory unit, a PCIe-x1 extension unit, a multimode network testing module, a dual-path WLAN (Wireless Local Area Network) module, a GPS (Global Positioning System) module and a motion sensor. The multimode network road tester provided by the invention has the advantages that the multimode network road tester based on the ARM (Advanced RISC Machines) Cortex-A8 processor is integrated with multimode network test and internally provided with the motion sensor, so that geographic location information of a tester is convenient to provide under the condition of switching an outdoor test into an indoor test; a multipath wireless network test module supports hot plug, so that it is convenient for road testing personnel to just carry out simple treatment without a shutdown operation when a test module is necessary to replace; and the multimode network road tester has the characteristics of small size, low power consumption, direct human-machine interface, convenience for operation, and capabilities of largely relieving burden of road testing personnel and realizing continuous test under the situation without a standby battery.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a multi-standard network drive tester based on an ARM Cortex-A8 processor which is used for mobile communication network coverage and wireless network quality testing and does not generate any harmful interference to other communication systems. Background technique [0002] The drive test is to test the downlink signal of the wireless network, that is, the air interface of the wireless network. It is mainly used to obtain the following data: signal strength of the serving cell, voice quality, signal strength and quality of adjacent cells, handover and access signal Order process, cell identification code, area identification code, geographical location information of the mobile phone, call management, mobile management, etc. Its function mainly lies in the evaluation of wireless network quality and the optimization of wireless network. [0003] At present, the ev...

AI Technical Summary

Problems solved by technology

This method uses many components. Due to the bumps of the vehicle, each component is prone to poor contact, which will cause data failure and reduce the accuracy of the test.

In order to solve some problems in the first method, another test equipment appeared, that is, the second method, integrated wireless network drive test equipment, which fixes the computer and power supply device used for drive test in a closed In the chassis, GPS and multiple test terminals are fixed on the outer surface of the chassis and connected to the computer through the interface. This can only solve the problems of data failure and inconvenient use caused by too many components and cables.

There are still problems of large size and power consumption

There is another way, that is, the third way, the vehicle-mounted terminal of the drive test system. In order to facilitate the plugging and unplugging of the test terminal, it supports the plugging and unplugging of various business modules. It only solves the plugging and unplugging of various business modules. There are still various application inconveniences, such as: the volume and power consumption of the device are still too large to meet the requirements of today's portable mobile, there are many problems in the above three methods, the battery life of the notebook computer is short, The working time is less than 3 hours when the vehicle power supply is not used; it is heavy and heavy, and it is inconvenient to move; multi-network tests need to be replaced with different test mobile phones or test terminals, which is not convenient for hot swapping, etc.
