The module was designed as a single-board microprocessor system based on a 32-bit microcontroller with an Arm Cortex core. It is made in SMD technology. Its dimensions and shape allow for installation directly on the engine, under the compressor inlet cover.
As part of the implementation of the assumption of maximum flexibility, mechanisms are introduced to adapt to various electrical requirements of cooperating elements - valves, pump, starter, power source. The extensive menu provides the ability to set parameters and save them in three arbitrary sets apart from the factory one, programmed in the production process.
A large number of available parameters provides full control over each stage of the turbine's operation. The extensive user interface provides current information on the turbine's operating status and all historical data from previous work cycles.
The system has two interfaces for external communication. One of them is used to connect the GSU interface with an LCD display and a small basic information module with LEDs and an acoustic signal. It also has a button to start the fuel pump and open the main valve.
The second interface is used for two-way communication with the Bluetooth module or transmission of measurement data via the RS232 serial port. Bluetooth communication ensures cooperation with an application installed on mobile devices, which is used to modify parameters and read the current operating status of the turbine.
To ensure maximum protection of the turbine engine and all aspects of safety of use, advanced algorithms for controlling operating parameters have been used. This applies to exceedances and failures to complete the set stages. All emergency events are saved in non-volatile memory for later analysis.
For service purposes, dedicated software (optional) is used, which cooperates with the control module via a bidirectional serial transmission interface (photo 1). The collected measurement data, after being displayed in graphical form, provide full information about the operation of the turbine (photo 2).
