Darren's Project Presentation 8051 Controlled Speedo For a Trolley On An Inclined Ramp
Background: Technology Being Replaced • Outgoing technology includes: • Bulky DC Power Supply • Optical Sensor • Portable Digital Scope • Pen, Paper & Calculator
Background: Spec provided. • Design Spec. provided by ANECTO Ltd. • Simple device set-up • User friendly display module • Idiot-proof operation • Easily verified output (by operator if possible) • Clear & concise documentation
Operator Time Optimization • Replacement device will eliminate slow & unreliable operator calculations • Faster test set-up • Errors will be avoided • Reduced cost to the paying customer
Main Technologies Employed • 8051 Microcontroller • SX-461 Opto-switch • LCD Display • Capable of independent operation • System to be expanded to relay it’s readings to PC • Serial or USB? • Reliability Issues? • Connectivity?
8051 Development Board • 62 Kbytes On-Chip Flash/EE Program Memory • Sufficient for reasonably large source code • Built in Interrupt based timer • Can be configured for 16-bit operation • On-board Serial communications
PC Based User Interface • System to receive data from core test unit • Data from various tests to be stored & easily accessed • Statistical analysis to be carried out on acquired data • PC Interface to transmit calibration data back to the core test unit
Research & Implementation Goals • Re-acquaint myself with the 8051 • Implement & test all basic functions required • Much of the code design is completed • Construct a standalone, fully enclosed unit ready for initial use & testing (ASAP) • Testing of Serial/USB functionality thereafter • Finally, a PC based application will be constructed
Goals (Monthly) • November • Installation of the basic unit for parallel operation with existing system • December • Functional system in place & verified • January • PC based application to be complete & in testing • Febuary • System complete & write-up underway
Review Schedule • Reviews may be at any point you wish • Weekly e-mail will detail progress • Full review after each major milestone
Contingency for Change of Plan • There will be several months available for tidying up the code & hardware towards the end of the project • If a deadline is overshot the time will have to be made up ahead of the next one
Initial Strategy • Construction of the Development System as a test-bench unit • 8051 Dev. Board & PSU • LCD & PSU • Optical sensor & PSU • Installation & test of a rudimentary unit • Integrated system with only one PSU for the core unit • Further development to follow
