Design of a rescue button for emergency calls in cars
Jarabý, Šimon ; Jeřábek, Jan (oponent) ; Dvořák, Jan (vedoucí práce)
This bachelor’s thesis focuses on the design and implementation of a prototype device, which aims to retrofit vehicles manufactured before 2018 with an emergency call sys- tem. The device will operate on similar principles as the eCall service introduced by the European Union. The first part of the work contains a basic acquaintance with the used technologies and procedures in the proposed devices. Since this is a device intended for cars, we perform this retrofit by connecting the device to the OBD-II (On Board Diagnostics) diagnostic connector. For this reason, in the theoretical part we get acquainted with the diagnostic connector OBD-II as well as with the CAN bus, com- munication protocols or the method of accident evaluation. The practical part with the subsequent design of equipment and selection of individual components. We will need to send location and communication from the devices via the 3G network, which is why we choose the Global Positioning System (GPS) and Global System for Mobile Commu- nications (GSM) modules. We will also evaluate the accident using an accelerometer so that we can determine the severity of the accident. The last part of the work describes the practical construction and implemented equipment.
