Electronic Design
Pi Micros has been designing computer based systems and interfaces for over 40 years. Out experience in design and circuit board layout, prototyping and testing allows us to make anything to solve any data gathering / processing / acquisition or industrial control problem.
We started designing micro processor systems in 1978 using
the 2650 processor from Signetics. Since then we have designed hardware and
embedded firmware for a variety of micros from AVR, TI, NEC, Mitsubishi,
Intel, Zilog, Motorola, ARM & SGS Thompson.
This is all done locally in Sydney with all local knowledge and experience. We can consult with you in your office or site and work with you directly to solve your problems. Some examples ...
Industrial Modules:
Pi Micros has developed a suite of application independent, networkable modules which can be distributed throughout an industrial site (or machine) performing functions such as temperature measurement, analogue input / output, isolated input and relay output. The control module (CM) contains an LCD, keypad and RS232 interface.
These were used in ..
Environmental Test Chamber
This project for the National Standards Commission of Australia, is a climate controlled room controlled by Pi Micros' modules which in turn receive the climatic targets from a PC. The firmware developed by us must continually monitor temperature & humidity, controlling the power level of the air heaters, humidifier and the operation of the refrigeration unit. A LCD and keypad for diagnostics & servicing is also used.
Freezers for Allied Refrigeration and Engineering:
A range of single and double stage freezers developed by Allied are controlled by the same modules. The firmware controls the compressor, fans & pump while monitoring temperature and other status information to bring the unit to the specified temperature or through the required freezing cycle. Commands are received through a keypad and status is displayed on an LCD.
Other designs include ...
Current Loop Interface:
This interface module, developed for Caltex Australia, was required to allow a Yokogawa controller to collect data from Caltex's legacy tank farm.
DLU32: Data Logger:
Working as a USB interface module for a laptop, Pi Micros developed this logging system for the elevator industry to keep track of landing call waiting times and allow diagnosis of complex lift controller faults. The unit includes 32 industrial voltage, bi-polar, optically isolated inputs and a USB port for connection to the laptop which is used for storage, setup and input state display. The 32 inputs are arranged in a matrix to minimize the amount of harware required. See DLU32.
