Module whalenotice

source code

Autogenerated python functions to serialize/deserialize binary messages.

Generated by: ./aisxmlbinmsg2py.py

Need to then wrap these functions with the outer AIS packet and then convert the whole binary blob to a NMEA string. Those functions are not currently provided in this file.

serialize: python to ais binary deserialize: ais binary to python

The generated code uses translators.py, binary.py, and aisstring.py which should be packaged with the resulting files.


Requires:

Author: xmlbinmsg

Version: 4791

Status: under development

License: Generated code has no license

To Do: FIX: put in a description of the message here with fields and types.

encode(params, validate=False)

source code 

Create a whalenotice binary message payload to pack into an AIS Msg whalenotice.

Fields in params:
  • dac(uint): Designated Area Code (field automatically set to "366")
  • fid(uint): Functional Identifier (field automatically set to "1")
  • efid(uint): extended functional identifier (dac+fid+id defines which message) (field automatically set to "2")
  • timetag_month(uint): Time whale was last recorded month 1..12
  • timetag_day(uint): Time whale was last recorded day of the month 1..31
  • timetag_hour(uint): Time whale was last recorded UTC hours 0..23
  • timetag_min(uint): Time whale was last recorded minutes
  • timetag_sec(uint): Time whale was last recorded seconds
  • stationid(aisstr6): Character identifier of the station. Usually a number.
  • station_longitude(decimal): Location of the sensor taking the water level measurement or position of prediction East West location
  • station_latitude(decimal): Location of the sensor taking the water level measurement or position of prediction North South location
  • whale_longitude(decimal): Where was the whale East West location
  • whale_latitude(decimal): Where was the whale North South location
  • timetoexpire(uint): Seconds until this notice expires
  • radius(uint): Distance of the required exclusion/slow zone
  • heading(uint): Direction the whale is traveling
  • numWhales(uint): Number of whales detected
Parameters:
  • params - Dictionary of field names/values. Throws a ValueError exception if required is missing
  • validate - Set to true to cause checking to occur. Runs slower. FIX: not implemented.
Returns: BitVector
encoded binary message (for binary messages, this needs to be wrapped in a msg 8

Note: The returned bits may not be 6 bit aligned. It is up to you to pad out the bits.

Warning: this will take invalid keys happily and do what???
