Project Overview

The goal of this project is to create a new embedded controller system for plastic recycling and manufacturing equipment. The current system can be view on the injection machine located here

The current plastic electrical system contains two MYPIN TA temperature controllers that use PID and PWM to drive SSRs connected to heating elements monitored by K thermocouples. The system also has a time-controlled relay that is used drive and hold a pneumatic piston for a set time duration.

The new embedded controller system should replace the two MYPINS and the time-controlled relay with a single embedded microcontroller system (e.g. Beagle Bone Black, Raspberry Pi). The system should work stand alone and connect to Wifi. This includes a user interface that replicates the ability to set temperatures/times, view current state, and operate the device. When connected to the internet, the embedded controller should act as an IOT endpoint with connections to the cloud via services like AWS IOT core. Messaging services, like MQTT, to the cloud will allow for data collection, future data analytics, and remote device monitoring /control.
