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
Grafana Interface Added
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 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.
2020
Sensor network expanded
- ShopB
- Motion
- Temp
- Outdoor Temp
- ConfRm
- Motion
- Temp
- ElecRm
- Motion
- Temp
Internal HAL GUI implemented (python + pyside2)
Web Synoptic View Implemented
HAL internal mounting board added.
HAL interface & protection board added (See HAL-2 in the Problem Reports)
2017
HAL was created??? [Needs Confirmation]
Maintenance Notes
HAL Enclosure
Written 2023-10-04. The new HAL enclosure with the screen requires the entire raspberry pi be removed before maintenance. This is because of a design oversight and may be resolved by the time another internal electronics mounting board is developed.
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
