PRS - Airborne Monitoring and Control Systems

Welcome on Airborne Monitoring and Control Systems webpage - A3M38PRS. You will find basic information here necessary for successful fulfillment of all requirements. This subject is taught by people from Laboratory of Aerospace Information Systems that belongs under Department of Measurement (K13138), Faculty of Electrical Engineering, Czech Technical University in Prague.


 

Subject

Target group: Target audience is represented by students who wants to know more about airplanes' board instruments systems used on small, ultra-light (UL), bigger (VLA), and bigger (GA), and a little bit bigger (CS23) machines, that fly in the Earth's atmosphere. The lectures are then extended about information related to spacecraft board instruments systems. Emphasis is placed on display instruments and generally on human-machine interaction.

Concept: The Subject is composed from lectures where students gain information that are used during laboratory exercises later. Exercises are divided into three blocks. First block introduces students into a simulator of an embedded system used for development of glass-cockpit visualization software - it is available for home usage. Students will design and develop one of the systems used onboard of modern airplanes. Next block is a set of measurement tasks, that demonstrates system principles and measurements necessary for successful certification of a new instrument. The subject ends by connection of developed instruments to a flight simulator and usage of developed instruments for guidance of the airplane..

Individual assignments

Students will develop a system representing information flow from a magnitude sensor to a display element. First part of the assignment consists in survey about basic information related to assigned magnitude - that is measured and displayed on the airplane dashboard. The first part is a documentation including following information:

  • Introduction and importance of the assigned magnitude for airplane control
  • Equations used to calculate assigned magnitude and description of all variables. In case your magnitude is not directly based on a physical principle you can place a short description of the measurement system into your presentation - like in case of GPS.
  • Sensors used for measurements of this magnitude, their principles.
  • Answer how are data transferred from sensor to the display instruments - analogue transmissions
  • What data packets carry assigned magnitude (definition according to ARINC429, ARINC629, CanAerospace, ...)
  • What display instruments are generally used: analogue, digital, displays - and try to predict what shape will be used in future.
  • Drawing of its face, scales and control items.
  • Description of control items.
  • Example of installation in an airplane.
  • What shape will be implemented by your team in digital form? Minimum and maximum values.
  • Percentage of participation of each team member - either on presentation preparation, programming or final report - in case of at least two people in the group all team members should participate on presentation.
  • Take care about proper citing of work of others.

The documentation will be presented by the team in the first half of the term during exercises. The presentation will be evaluated according to the level of details - see marks at the end of this page.

Second part of the laboratory exercises consists of development of two programs. First program will allow setting of a value of the assigned magnitude by a suitable control item - slider. The controlled value will be sent to the second program in CANaerospace format in a UDP packet. The second program represents a display instrument.

There are two program stubs prepared for students:

  • Base of a generator and.
  • base of a display instrument - will be presented on the first laboratory exercise.

The CANaerospace data transmission in UDP packets needs translation from CAN to an array that will be send over TCP/IP from Magnitude Generator to Magnitude Instrument. Data packet is defined as follows:

Header - CAN ID Length Data
MSB     LSB                  
[0] [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12]
ID[0] ID[1] ID[2] ID[3] Length DATA[0] DATA[1] DATA[2] DATA[3] DATA[4] DATA[5] DATA[6] DATA[7]

Meaning of single items is as follows:

  • ID - is a CAN ID - see CANaerospace definition.
  • Length - represents length of the DATA array.
  • DATA - carries single data bytes.
