TIMS, or Telecommunication Instructional Modeling System, is an electronic device developed by Emona that is used as a telecommunications trainer in educational settings and universities.[1][2][3]

History[edit]

TIMS was designed at the University of New South Wales by Tim Hooper in 1971. It was developed to run student experiments for electrical engineering communications courses.[4][non-primary source needed] Hooper’s concept was developed into the current TIMS model in the late 1980s.[5][non-primary source needed] In 1986, the TIMS project won a competition organized by Electronics Australia for development work using the Texas Instruments TMS320.[4][non-primary source needed] Emona Instruments also received an award for TIMS at the fifth Secrets of Australian ICT Innovation Competition.[6]

Methodology[edit]

TIMS uses a block diagram-based interface for experiments in the classroom. TIMS can model mathematical equations to simulate electric signals, or it can use block diagrams to simulate telecommunications systems.[5][non-primary source needed][7][non-primary source needed] It uses a different hardware card to represent functions for each block of the diagram.[8]

TIMS consists of a server, a chassis, and boards that can emulate the configurations of a telecommunications system.[9] TIMS uses electronic circuits as modules to simulate the components of analog and digital communications systems.[10][11] TIMS modules can perform different functions such as signal generation, signal processing, signal measurement, and digital signal processing.[7][10]

Variants[edit]

  • TIMS-301, a basic communications training system capable of simulating modulation schemes such as AM, FM, PSK, and others.[12][13][14] The TIMS-301 contains a system unit for fixed modules, which simulate amplification and electronic oscillation, and 12 slots for plug-in modules, which simulate single function building blocks.[15]
  • ETT-101 Biskit, a simpler training system with fixed modules and more limited capabilities, suitable for introductory purposes.[2][15][16]
  • TutorTIMS, a simulation with GUI based on the same modular block diagram as TIMS hardware.[17][18] It contains the same features and modules as the TIMS tutorial system in virtual form.[19] Like the TIMS-301, it can be used to simulate amplitude modulation.[20]
  • netTIMS, developed to meet the requirements of distance learning. NetTIMS is hardware equipment controlled via a browser across LAN or internet. Students can vary control parameters but cannot change connections except scope points for viewing signals.[21]
  • netCIRCUITlabs, a cloud platform that is based on rapid-shaping FPGA technology. It was developed to provide remote access hardware labs in analog & digital electronics introductory courses.[22][23][24]
  • Freewire, used for remote access labs in introductory telecoms/wireless classes.[25]
