Challenge, Approach, Outcome

1

Challenge

A modular building control centre for smoke detection and smoke/heat extraction needed firmware for heterogeneous modules — certifiable to ISO 21927-9 and updatable building-wide.

2

Approach

FreeRTOS/C++ firmware per module with custom bootloaders for building-wide updates, RS485 networking, digital I/O for sensors and actuators, and a TouchGFX GUI on STM32F4.

3

Outcome

A configurable, extendable control centre that automatically operates windows and alarms based on sensor input, certified to ISO 21927-9.

Project Description

The project focused on providing a firmware for several modules of control center including a custom bootloader. The modules were fitted with different microcontrollers, including a STM32F4xxx for an embedded GUI (touchgfx).

The center could react to digital inputs and trigger outputs/alarms. The whole unit is extendable and configurable depending on the outfitting of a building.

Windows could be automatically opened and closed, depending on sensory input from the environment.

The project conforms to the ISO 21927-9 standard.
