2 ． Specification
2.1 Protective Capsule Unit: PCU (NDH-317)
(1) Function:
The P
rotective Capsule Unit (PCU)
is not a float-free type but a fixed type. The
PCU
records navigation data, hull data, conversation in the bridge, conversation over VHF
radio, and radar image data to the recording medium in the
PCU
.
When submerged, the
Underwater Acoustic Beacon
with
PCU
, which is battery-powered,
transmits pulsed acoustic signal for capsule searchers.
(2) Performance:
a) Interface:
1) Standard: IEEE802.3 (10Base-T/ 100Base-TX)
2) Protocol: TCP/IP
b) Recording duration and capacity:
1) Duration: 12 hours
2) Capacity: 2.0GB (flash memory)
c) Data Recording Interval:
1) Sensor Data: depends on the input from the sensors (normally 1 second)
2) Audio Data: continuous (1 audio file / minute)
3) Image Data: 1 image per 15 second (Option)
d) Acoustic underwater beacon:
1) Operating frequency: 37.5kHz ±1kHz
2) Operating time: minimum 30 days after submerged in the water
3) Detectable range: 1800m - 3600m
(depends on surrounding environment)
4) Battery life: maximum 5-years
(3) Environmental condition
