UCSS is an integrated system (electronic device and computer-based software) designed as a universal and scalable system for control and security applications. The electronic device is an embedded system consisting of a microprocessor (Rabbit 2000 microprocessor) and a set of separate electronic cards that can be inserted according to the requirements of the application. The electronic unit features various communication capabilities, enabling the building to be monitored and controlled remotely from anywhere, at any time, utilizing current wireless data technologies such as GSM, SMS, and GPRS. In addition to computer networks (Ethernet, Wi-Fi) and the internet (HTTP, FTP). The 3D-Eye system is a network-based computer software with a 3D graphical user interface used to control and monitor smart buildings. Using the 3D interface, the system can monitor and control various building devices, including elevators, escalators, laser detectors, and air conditioning systems. The system also provides various tools and options to display and store videos from the monitoring cameras. In order to test the UCSS system from the early development stages, we designed a building model equivalent to the real operating environment. The model has: Elevator & escalator systems (3 Floors). Automatic doors. Security system with laser and monitoring cameras. Fire alarm system. Lighting system.
