IntelliJ base project related to Minecraft Lab of 221_SIn & 231_SIn course

## Purpose
|
|
|
|
|
This project is made during the 4th semester of study in Industrial Systems at the University of Engineering in Sion,
|
|
|
|
|
Wallis, Switzerland. It is used to learn the basics of DevOps, Database, web development and modbus communication.
|
|
|
|
|
This project is made by a group of 2 students. This project was made during 7 weeks and cut into 6 parts.
|
|
|
|
|
The goal of this project is to interface a Minecraft mod. This mod is a simulation of a micro-gri. Our goal is to
|
|
|
|
|
read electrical value from the Minecraft world and save it in database, display it on a web page and finally send
|
|
|
|
|
regulation value to the Minecraft world for keep the micro-gri stable.
|
|
|
|
|
To reach this goal, we have to use a modbus communication between the Minecraft world and our program.
|
|
|
|
|
The program is divided into 6 parts:
|
|
|
|
|
|
|
|
|
|
### Core part
|
|
|
|
|
The core part is the main part of the project. It is the part that will be used to communicate with the other parts.
|
|
|
|
|
In Core, we have the management of DataPoints. A DataPoint is a virtual copy of a Minecraft input or output. In Core,
|
|
|
|
|
we have a static Map of DataPoints. The key of the map is the name of the DataPoint and the value is the DataPoint
|
|
|
|
|
itself. The DataPoint class is an abstract class. It has 2 subclasses, FloatDataPoint and BooleanDataPoint.
|
|
|
|
|
|
|
|
|
|
### Database part
|
|
|
|
|
The database part is the part that will be used to store the DataPoints. All DataPoints are send with a http POST
|
|
|
|
|
request to the database. The database use in this project is InfluxDB. InfluxDB is a time series database. We use
|
|
|
|
|
after Grafana to display the data. Database part can also erase all the data in the database.
|
|
|
|
|
The time management is also on this class. The goal of this class is to convert the time from the Minecraft server
|
|
|
|
|
to the real time. We start to send data to the database only when the Minecraft server is started.
|
|
|
|
|
|
|
|
|
|
### Web part
|
|
|
|
|
The web part is the part that will be used to display the data from the database. We already have a web page that is
|
|
|
|
|
given by teacher. We use a websocket to interface with web page. With this web page we can read Minecraft data and
|
|
|
|
|
set some regulation value. We also add a switch to start or stop the smart part.
|
|
|
|
|
|
|
|
|
|
### Modbus part
|
|
|
|
|
The modbus part is the part that will be used to communicate with the Minecraft world. We use the modbus TCP
|
|
|
|
|
communication. We use the library modbus4j.
|
|
|
|
|
|
|
|
|
|
### Field part
|
|
|
|
|
The field part is the part that will be used to connect modbus part to the core part. We read a csv file to know all
|
|
|
|
|
the modbus address and the name of the DataPoint. With this file, we can link DataPoint to minecraft input or output.
|
|
|
|
|
|
|
|
|
|
### Smart part
|
|
|
|
|
The smart part is the part that will be used to send regulation value to the Minecraft world. We make a very simple
|
|
|
|
|
regulation just for keep the grid alive during the time of the simulation. We stop our program when the Minecraft
|
|
|
|
|
simulation send a score. This score is how many production we have made with the factory during the simulation. So
|
|
|
|
|
the goal is to maximize this score. We didn't have time to make a better regulation.
|
|
|
|
|
|
|
|
|
|
## How to use
|
|
|
|
|
To use this project you can just download the last release and run the JAR file with some arguments.
|
|
|
|
|
The arguments are:
