The development of microprocessor-based digital devices of monitoring and control

The authors develop a digital device for the protection of movable property. The device is GSM-GPS alarm designed to guard bicycle, scooter and car. The installed GPS-GSM modules allow for tracking location of movable property and to exercise control signaling at any time. Device is based on SMS commands and calls that are sent from a mobile phone. The unit can store up to 10 mobile numbers of users. In order to safely control the device, its software provides protection against SMS attacks coming from Internet resources. In modern conditions, remote monitoring is often carried out via the Internet connection. The device will consist of two parts: the visible part that is installed on the frame of the vehicle, and the hidden part installed in the steering column or the steering wheel handle. Developed security devices are necessary to ensure uninterrupted supply during the performance of its functions. In addition, its visible part must be resistant to impact from the outside. Advantage of the developed device is the low price and the possibility of expanding the functionality. The developed device will be in demand, as a modern society needs to have immediate control over the objects of ownership.
