Refrigeration
Temperature Controller
Project Description
The Project included the
hardware and software development necessary to upgrade an existing product line.
The project involved redesigning the hardware in such a manner as to give the
product flash programming capability for the sake of field software upgrades,
bank switching for larger program area, increased nonvolatile memory area, increased
I/O, and increased analog to digital conversion inputs.
Skills Required
- The hardware side of
the project was performed in a turnkey manner. The customer provided the specifications
and the schematics of the existing unit and Embedded Systems provided the
services necessary to produce hardware within four months. The skills required
included project management, electrical engineering, schematic capture(ORCAD),
printed circuit design (CALAY CADCAM) and the production engineering necessary
to make a smooth transition into production.
- Because of the different
nature of the software development and the proprietary knowledge involved,
the software was done on-site in the customer's facility. The skills involved
were PL/M programming, assembly language, and software engineers with a good
working knowledge of the hardware.
Services Used
- Turnkey hardware development,
including electrical engineering, CAD, CAM and
production coordination.
- Software development,
programming in PL/M 51 and 8051 assembly language.
Project Size
- Embedded Systems has
provided the customer with a five man team for the past eighteen
months.
Customer
- A local transportation
refrigeration company.
