Plumbing – Valves

Solenoid Valves




12 DC 0.25A
Operating Range 0 – 40 psi
Normally Closed
Air Relief Valves


Removes air from line
Need to be oriented at an apex

Circuitry





Parallel Port
PAL Chip
Darlington Circuit
Next State Logic
Java-based Hardware Drivers
Circuitry – Parallel Port

Parallel Port Pin out



Line Control (Bits 0 – 4 )
Solenoid Control (Bits 5,6)
System Pause (Bit 7)
Circuitry – PAL Chip




System calls for 64 solenoid valves to
be controlled by 7 bits.
PAL chips allow for full selection
programming
Global reset can be include in PAL
PAL also can fake internal clock
Circuitry – Darlington Circuit


Solenoid valves require more voltage
and current than normal TTL
Darlington circuit – consists of pair of
BJT transistors


Able to drive large load
5V TTL compatible

Database System




Database Manager – PostgreSQL
Scheme - UML Diagram
Database Drivers (JDBD and Custom)
Add/Delete/Modify as Triggers
Database – PostgreSQL

PostgreSQL - Database Manager




Freely Available
Cross-Platform Capable
Object-Oriented Database
PGAdmin – Database Utility


Graphically manage database
Shell provided to execute SQL queries
Database – UML Diagram
FK – Foreign Key
PK – Primary Key
Bold – Required
Database – JDBC Driver

JDBC – Java driver package



Library of function calls specific to the
database manager (PostgreSQL)
These function calls allow for connections,
queries, and updates to the database
Required in the CLASSPATH
Database – Custom Drivers

Custom Java-based Database Drivers

Database Controller



Drink Controller


Establishes connection to database
Queries the database
Retrieves and stores data that involve drinks
including their recipes and ingredients
Cabinet Controller

Retrieves and stores data that is involve with the
physical components (Bottles used, Quantity, etc)
Database - Triggers

Triggers




SQL code sequences
Stored within the Database Manager
Executed locally to the Database Manager
Possible Trigger Implementation


Adding/Deleting/Updating data where
constraints exist
Example – Adding an ingredient for a drink
Software - GUI
