‘Global-Technologies’, is a system
engineering company that develops
measurement systems for different industries
to support a wide range of applications.
You have been asked as an engineer in the
‘Global- Technologies’ company, to design
and develop a measurement system that is
able to demonstrate the operation of crane
‘Load Moment Indicator’ (LMI) system using
sensors model. The measurement system
includes the measurement of crane boom
length, boom angle, load, outrigger position,
and driver cabinet temperature.
Provide a detailed, professional report for
your director that contains the following:
1- A review of different LMI systems used
in cranes industry including their main
2- A design of a typical LMI system that incorporates the measurement of crane
parameters including boom length, boom angle, load, outriggers position, and
temperature. The system design should include DAQ/ microcontroller and any
other required elements for a typical LMI system.
3- A measurement software program (LabVIEW/ C++) that can be used to provide
the following parameters, log the measurement data, and give warning alarms
when limits of the following parameters are exceeded.
➢ Boom length
➢ Outriggers position
➢ Driver cabinet temperature
4- Experimental results and critical analysis that evaluate two sensors of the LMI
system using the NI DAQ/ Microcontroller and NI LabVIEW/ C++ software.
5- An evaluation of signal conditioning elements that are required to measure the
load using strain gauges.
6- Proposal for the next phases of development to include the following:
A. Using of a low-cost controller instead of the current one
B. Other methods of data transmissions; wireless or wired data transmission,
and use of the internet of things
