- Abstract
- The thesis focuses on the evaluation and testing of FLEXNET, an Unattended Ground Sensor (UGS) system developed by Bertin Exensor. The primary purpose of FLEXNET is to monitor large areas without requiring extensive resources in the form of personnel actively monitoring and maintaining the system on site.
In the development of comprehensive systems it can often be challenging to carry out full-scale tests of the entire system within the confines of a company's own premises. Currently for more extensive tests the company has been forced to set up the entire system in the field. This has proven to be very resource-intensive, and the parameters of the environment can vary from day to day. Therefore, this thesis, in consultation with the...

In the development of comprehensive systems it can often be challenging to carry out full-scale tests of the entire system within the confines of a company's own premises. Currently for more extensive tests the company has been forced to set up the entire system in the field. This has proven to be very resource-intensive, and the parameters of the environment can vary from day to day. Therefore, this thesis, in consultation with the company, explores and implements the possibility of testing a complete system using a Raspberry Pi and Python to simulate an operational environment for the system inside the office. The goal of the thesis is to develop a reliable and comprehensive test rig that makes it easier for employees to continuously test their products without having to leave the office.
The development process was carried out in several stages. Initially, the thesis workers explored methods for physically connecting to the devices. Subsequently, sensor data was generated for the sensors to evaluate whether it resulted in an adequate alarm signal. Finally, several sensors were fed data simultaneously to analyze the overall system's interactions. The results from the thesis indicate that it is possible to use a Raspberry Pi to simulate an operational environment for the system within the office setting. Additionally, it provides and scores valuable information about the system's performance using statistical modeling. (Less) - Abstract (Swedish)
- Examensarbetet fokuserar på utvärdering samt testning av FLEXNET, ett Unattended Ground Sensor (UGS) system utvecklat av Bertin Exensor. FLEXNET:s grund-läggande syfte är att övervaka stora områden utan att kräva omfattande resurser i form av personal som aktivt övervakar och underhåller systemet på plats.
Vid utvecklandet av större system kan det ofta vara besvärligt att utföra fullskaliga tester av hela systemet i företagets egna lokaler. I dagsläget har företaget vid mer omfattande test, tvingats rigga upp hela systemet ute i fält. Detta har visat sig vara mycket resurskrävande samt att omgivningens parametrar kan variera från dag till dag. Därför undersöker och implementerar detta examensarbete i samråd med företaget, möjligheten...

I dagsläget har företaget vid mer omfattande test, tvingats rigga upp hela systemet ute i fält. Detta har visat sig vara mycket resurskrävande samt att omgivningens parametrar kan variera från dag till dag. Därför undersöker och implementerar detta examensarbete i samråd med företaget, möjligheten att testa ett komplett system med hjälp av en Raspberry Pi och Python för att simulera en utomhusmiljö för systemet i företagets lokaler. Målet med examensarbetet är att utveckla en pålitlig och omfattande testrigg som underlättar för de anställda att fortlöpande testa sina produkter utan att behöva lämna kontoret.
Utvecklingsprocessen genomfördes i flera etapper. Inledningsvis utforskade examensarbetarna metoder för att fysiskt ansluta till enheterna. Därefter genereras sensordata till sensorerna för att utvärdera om det resulterar i en adekvat larmsignal. Slutligen skickades data till flera sensorer simultant för att analysera det övergripande systemets interaktioner. Resultaten från examensarbetet indikerar att det är möjligt att använda en Raspberry Pi för att simulera en utomhusmiljö för systemet inom kontorsmiljön. Dessutom erhålls värdefull information om systemets prestanda med hjälp av statistisk modellering. (Less)
