DARREN'S PROJECT PRESENTATION8051 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
1. Construction of the Development System as a test-bench unit
8051 Dev. Board & PSU LCD & PSU Optical sensor & PSU
2. Installation & test of a rudimentary unit Integrated system with only one PSU for the
core unit
3. Further development to follow
