HAL

HAL is MAG Laboratory's motion, door, and open status monitor.

Design

HAL is based on the raspberry-pi (one) model B and uses the PI's GPIO pins to interface with the outside world.

There is a hardware design document on Google Drive.

History

2022

HAL GUI updated with better fan controls

• Still not feature-complete

Temperature Network Restart Added (problem report not written)

• Restarts the HAL temperature sensor network when outages or over-current conditions are detected
• MIC2090 chip used. 100mA current on the 5V line.

Grafana Interface Added

• https://jane.maglab:3000/d/-Sc7CXl7z/hal-comprehensive

InfluxDB Logging Started

2021

Internal HAL GUI prototype released (C#, mono)

• 12"_Axial_Ventilation_Fan GUI implemented

Fan (motor) temperature sensor attached

LT3960 differential one-wire implemented.

• using 5V power directly connected to VCC instead of the 3v3 internal LDO
• the termination resistors are set to the 100 ohm impedance of Ethernet rather than the standard 120 ohm CAN termination

Temperature sensor network restart under fault

2020

Sensor network expanded

Internal HAL GUI implemented (python + pyside2)

Web Synoptic View Implemented

HAL synoptic view 2020

HAL internal mounting board added.

HAL hardware 2020

HAL interface & protection board added (See HAL-2 in the Problem Reports)

2017

HAL was created??? ^{[Needs Confirmation]}

Problem Reports

HAL-1 : "Main Door" does not describe the door being monitored

HAL-2 : Haldor Board is not Sufficiently Skookum for Safety

HAL-3 : A synoptic view should be implemented

HAL-4 : An Auto Updating Feature Should be Implemented
