Recording Control Unit

The host computer is applied the fanless embedded CPU from Advantech, Taiwan, data acquisition modules with internationally recognized digital format (IEC 61162 or NMEA 0183), audio process module, video data processing module, Ethernet management module and power supply management module

Alarm Unit includes

Communication process, LCD, buzzer, audio and visual alarm confirmation, which are fully accordance with the IEC performance standard for alarm and indicator

Protective Data Capsule (PDC)

The PDC can update the data acquired from the recording control unit continuously and save the last 12 hours data automatically as well as expand its memory to 24h, 48h

Microphone

Adapt the omni direction FET Electret type; the microphones are connected to the S-VDR recording control unit through the preamplifier in a balanced transmitting way. The S-VDR software can send out the testing signal as well.

Power Supply Unit

Adapt the power isolated transformer and UPS power supply and supply to the recording control unit which is satisfied the requirement of recording separately the sounds in the bridge at least 2 hours

Gyro Compass & Speed Log Interface (Optional)

The analog signals of the gyro compass or the pulse signals of the speed log can be converted into the standard IEC61162 data format.

Replay Device (Optional)

Re-play the data saved in the final recording medium

Voyage Data Collection: collect the voyage status and data, record these data into the final recording medium in the protective data capsule via 14 isolated RS422 COMs.

Audio Data Collection: the audio recording of every position in and outer bridge can be realized by 1-9 microphones. Meanwhile, record the audio signals in the devices such as 1-3 VHF, commanding telephone. The responding range of the audio frequency is 150Hz - 6000Hz.

Image Data Collection: optional with radar interface, collect the unicolor and multicolor radar images and record. Resolution: 640×350 - 1280×1024, refresh rate: 60Hz - 85Hz, collecting time: 15s

Data Storage: all collected data can be saved in both final recording medium and backup recording medium, which both should be provided with certain self-protection to prevent any delete or tamper on the recorded data.

Self-inspection: when the system starts running, the self-inspection starts up automatically and sends out a status indication showing if the system runs correctly. System will alarm for any abnormality.

Replay: replay the data stored in the final recording medium by the replay device. The data stored in the final recording medium and the backup recording medium can be downloaded via the internet COM and replayed by the replay device.
