Overall System Architecture Diagram: A visual representation of the central alarm system's components and their interactions, illustrating how hardware modules connect and communicate within the system.
Components of the Central Alarm System: The main hardware modules that comprise the system, including the central controller, detection devices, display units, and output modules.
Hardware Modules and Their Interactions: The physical units such as the STM32 microcontroller, UART/RS485 interface, EEPROM, LCD/OLED display, buzzer/relais, and detectors, along with the communication pathways (e.g., bus RS485) that enable data exchange and control signals among them.
Detector_t structure: A data structure representing each detector, containing fields such as address, type, state, description, zone, zone ID, last seen tick, alarm timestamp, last value, and enabled status. It encapsulates all necessary information for detector management and operation.
1. How does the overall system architecture influence the system's effectiveness in detecting alarms?
2. How can the detector configuration table be effectively used during system operation to update detector parameters?
3. During detector initialization, how does the system restore previously saved detector configurations from persistent storage?
