Systém prevence průniků využívající Raspberry Pi / Intrusion prevention system based on Raspberry PiHirš, David January 2021 (has links)
The number of discovered vulnerabilities rapidly increases. For example in 2019 there were discovered 20 362 vulnerabilities. The probability of cyber-attacks realization is high. Therefore it is necessary to propose and implement automated and low-cost Intrusion Prevention or Intrusion Detection Systems (IPS/IDS). This implemetation can focus on home use or small corporate networks. The main goal of the system is to detect or mitigate cyber-attack impact as fast as possible. The master's thesis proposes IPS/IDS based on Raspberry Pi that can detect and prevent various cyber-attacks. Contents of this thesis are focus on description of cyber-attacks based on ISO/OSI model's Link and Network layers. Then there is description of IPS/IDS systems and theirs open source representatives. The practical part is focus on experimental workspace, hardware consumption of choosen detection systems, cyber-attacks scenarios and own implementation of detection program. Detection program is based on these chosen systems and puts them together to be easily manageable.

Řídicí jednotka pro třídičku zkumavekBajtek, Tomáš January 2019 (has links)
This thesis examines a development process of a sample tube sorting machine, meant to serve in the university’s scientific workplace. This thesis follows an existing basic motion system. The thesis describes the function of the pneumatic components and their connection to the circuit necessary for carrying and placing the sample tubes. An important part of the thesis deals with designing the connection of a control unit, based on the Arduino and Raspbery Pi platforms. Such connection design consists of connecting the unit to the pneumatical sensors, switches and also the programming of the particular movement functions. Another part covers the ideas of potentional future development of the sorting machine.

Kameraövervakningssystem för fåglar med Raspberry PiMoza Orellana, Alfonso de Jesus January 2022 (has links)
Motivet bakom examensarbetet är att skapa ett kameraövervakningssystem, ämnadför att filma och fotografera fiskgjuseföräldrarna, när de är vid deras avkommor ifiskgjusebon. Inspelningarna och bilderna ska användas för att studera fiskgjuseför-äldrarnas beteende vid deras avkommor. Litteraturstudien visar att fiskgjusen skaparsina bon på höga plattkronade tallar. Dessutom att människors närvaro vid fiskgjuse-bona har en negativ påverkan, då fiskgjuseungar minskar i antal. Likväl har forskareskapat kameraövervakning ämnad för att filma fågelbo. Kameraövervakningssyste-met kommer att medföra att människors närvaro minimeras vid fiskgjuseboet. Nu-förtiden används generellt Raspberry Pi, vilket är en dator byggd på ett litetkretskort. Raspberry Pi kan anslutas med en kamera och lagra inspelningar på SD-minneskortet. Dessutom går det att ansluta diverse sensorer, installera diversemjukvaror och programmeras. Metoden för studien är att skriva koder för att skapa program som göra att Rasp-berry Pi startar inspelningar och tar foton. Dessa program skrivs i Python, biblioteksom Open CV och COCO datablad används. Studien omfattar en konstruktion av ett kameraövervakningssystem, med ett Rasp-berry Pi, högkvalitets kamera, infrarödsensor, ljudsensor och program för att ta fo-ton och starta filmningen. Filmerna sparas på SD-minneskortet. Kameraövervak-ningssystemet strömkälla blir en power bank. Resultatet blev ett program som tar ett foto när sensorerna detektera antingen infra-röd strålning eller ljud eller förändringar i pixlar från kamerabilden. Fotot analyserasav programmet för att se om det är några fåglar på fotot. I programmet går det attställa in hur många fåglar som ska vara med på bilden för att den ska starta inspelningoch spara fotot. Sedan gjordes ett program som hela tiden känner av om det finnsfåglar på kamerabilden. När önskvärda antal fåglar är med på kamerabilden, börjarkameran spela in och tar sedan ett foto. / The motive behind the thesis is to create a camera surveillance system, intended forfilming and photographing the osprey parents, when they are with their offspring, inthe osprey nest. The recordings and pictures will be used to study the osprey par-ents' behavior, nearby their offspring. The literature study shows that ospreys createtheir nests on tall, flat-crowned pines. In addition, the presence of humans near os-prey nests has a negative impact, as osprey chicks decrease in number. Nevertheless,researchers have created camera surveillance intended for filming bird nests. Thecamera surveillance system will minimize human presence at the osprey nest. Now-adays, the Raspberry Pi is used, which is a computer built on a small circuit board.The Raspberry Pi can be connected with a camera and store recordings on the SDmemory card. In addition, it is possible to connect various sensors, install varioussoftware and program. The method of the study is to write codes to create programs that make the Rasp-berry Pi start recording and taking photos. These programs are written in Python,libraries such as Open CV and COCO datasheets are used. The study includes the design of a camera surveillance system, with a Raspberry Pi,a high-quality camera, an infrared sensor, a sound sensor, a program for taking pho-tos and to start filming. The recordings and photos are saved on the SD memorycard. The camera surveillance system is powered by a power bank. The result was a program that takes a photo when the sensors detect either infraredradiation or sound or changes in pixels from the camera image. The photo is ana-lyzed by the program to see if there are any birds in the photo. In the program it ispossible to set how many birds should be in the picture for it to start recording andsave the photo. Then a program was made that continuously detects if there arebirds in the camera image. When the required number of birds is in the camera im-age, the camera starts recording and then takes a photo.

Design of a control and monitoring system to reduce traffic accidents due to drowsiness through image processingEraldo, Bruno, Quispe, Grimaldo, Chavez-Arias, Heyul, Raymundo-Ibanez, Carlos, Dominguez, Francisco 01 November 2019 (has links)
El texto completo de este trabajo no está disponible en el Repositorio Académico UPC por restricciones de la casa editorial donde ha sido publicado. / It is known that 33% of traffic accidents worldwide are caused by drunk driving or drowsiness [1] [2], so a drowsiness level detection system that integrates image processing was developed with the use of Raspberry Pi3 with the OpenCV library; and sensors such as MQ-3 that measures the percentage of alcohol and the S9 sensor that measures the heart rate. In addition, it has an alert system and as an interface for the visualization of the data measured by the sensors a touch screen. With the image processing technique, facial expressions are analyzed, while physiological behaviors such as heart rate and alcohol percentage are measured with the sensors. In image test training you get an accuracy of x in a response time of x seconds. On the other hand, the evaluation of the operation of the sensors in 90% effective. So the method developed is effective and feasible. / Revisión por pares
