Subsea Microcontroller Board
Overview
The Subsea Microcontroller Board, illustrated in
Error! Reference source not
found.
, controls all subsea system activity for Neptune 3000 and 5000
models. Depending upon the CPT model it is being used on different areas of
its functionality will be active. The Subsea Microcontroller Board performs the
following functions:
1.
Communication to/from Host PC via Telemetry board
2.
Cone data acquisition (RS485 or analogue)
3.
Motor Control via RS485 or discrete signals
4.
Inverter Pod status/control (Inverter Pod Voltage, Current,
Temperature, Humidity, and Control)
5.
Penetration distance monitoring from Encoder
6.
Cone position from Cone Up Sensor
7.
Onboard temperature and humidity sensing
8.
Onboard Frame Tilt Sensing or external Frame Tilt monitoring
9.
Hydrostatic Pressure monitoring (if pressure sensor fitted)
10.
10m and 100m Altimeter monitoring
Circuit Description
The circuit forms a full single board controller system. The board is supplied
with +12VDC for the main board supply and also +/-15VDC for all the
analogue cone circuits. The program code for the Subsea Microcontroller is
stored in onboard Flash memory and it is possible to reprogram the memory
in-system. Calibration data for the Frame Tilt sensors is stored in the EEPROM
memory.
