GoTrackery

• 🔭 I’m currently working on ...
• 👯 I’m looking to collaborate on ...

GoTrackery provides a server for obtaining geo-location from GPS trackers of their various protocols. The extracted geo-location data is converted into a single format and allows subscribers to process them in a single way. GoTrackery is CLI application made with Cobra.

GoTrackery has next features:

• Decode various telematic protocols;
• Handling various implementations of protocols (some vendors has not accurate implementation);
• Converting decoded data to unified data structure;
• Passing unified data structure to event subscrivers to support use for any purpose (i.e. saving into database, send message into message broker, calculate geofence events);
• Providing simple interfaces to implement new protocols.

Now implemented:

• Universal TCP server for tcp protocols;
• Universal TCP data replayer;
• Storing data into postgres example db;
• WialonsIPS protocol (partially - not all message types, no encoder);
• EGTS protocol (partially - not all message types);

How to

Build

Use make command to build executable:

• Linux: make linux
• Windows: make win
• MacOs Intel: make mac

Run

Use go run ./ --help to get info about flags and features.

• Run server with wialonips protocol: go run ./ tcp -p wialonips -a <address:port>
• Run player with previously recorded data. See how to do it here.

Store data

For now implemented only posgtresql storage.

• Run make db-up POSTGRES=<connection string> to create tables and stored proc in target postgre database;
• Create yaml config:

logging:
  level: debug
  console: true
tcp:
  address: :5000
  proto: egts
  socket-reuse-port: true
consumers:
  sample-db:
    uri:  <postgre connection string>

• Run server go run ./ tcp --config <path to config file>

Docker

It is possible to use prebuild docker image.

Also you can find docker-compose.yml example in examples folder to run along with Consul.

The Future

Shorterm Roadmap

• open telemetry (for server)
• replace generic message with protobuf message
• add mqtt event consumer with protobuf message
• protocol - wialon retranslator
• protocol - h02

Future plans for the implementation of other protocols see https://github.com/gotrackery/protocol

Midterm Roadmap

• move database store to mqtt subscriber
• more protocols (udp, mqtt, http)
• implement encoders (wialon ips)
• retranslators as mqtt subscriber

Longterm Roadmap

• Frontend
• Retranslator filter and subscribers
• Geofences https://github.com/peterstace/simplefeatures
• Event notificator
