Description
Receiver can parse EGTS binary package and save it in store, which connect as go plugin. Besides repo contains library for parsing EGTS bin data and can be use separately.

README
EGTS receiver
EGTS receiver server realization writen on Go.
Library for implementation EGTS protocol that parsing binary packag based on [GOST R 54619 - 2011](./docs`/gost54619-2011.pdf) and [Order No. 285 of the Ministry of Transport of Russia dated July 31, 2012](./docs/mitransNo285.pdf). Describe fields you can find in these documents.
More information you can read in article (Russian).
Server save all navigation data from EGTS_SR_POS_DATA section. If packet have several records with
EGTS_SR_POS_DATA section, it saves all of them.
Storage for data realized as plugins. Any plugin must have [store] section in configure file.
Plugin interface will be described below.
If configure file has't section for a plugin ([store]), then packet will be print to stdout.
Install
git clone https://github.com/kuznetsovin/egts-protocol
cd egts-protocol/tools && ./build-receiver.sh
Run
./receiver config.toml
config.toml - configure file
Config format
[srv]
host = "127.0.0.1"
port = "6000"
con_live_sec = 10
[log]
level = "DEBUG"
Parameters description:
- host - bind address
- port - bind port
- con_live_sec - if server not received data longer time in the parameter, then the connection is closed.
- log - logging level
Usage only Golang EGTS library
Example for encoding packet:
package main
import (
"github.com/kuznetsovin/egts-protocol/libs/egts"
"log"
)
func main() {
pkg := egts.Package{
ProtocolVersion: 1,
SecurityKeyID: 0,
Prefix: "00",
Route: "0",
EncryptionAlg: "00",
Compression: "0",
Priority: "11",
HeaderLength: 11,
HeaderEncoding: 0,
FrameDataLength: 3,
PacketIdentifier: 137,
PacketType: egts.PtResponsePacket,
HeaderCheckSum: 74,
ServicesFrameData: &egts.PtResponse{
ResponsePacketID: 14357,
ProcessingResult: 0,
},
}
rawPkg, err := pkg.Encode()
if err != nil {
log.Fatal(err)
}
log.Println("Bytes packet: ", rawPkg)
}
Example for decoding packet:
package main
import (
"github.com/kuznetsovin/egts-protocol/libs/egts"
"log"
)
func main() {
pkg := []byte{0x01, 0x00, 0x03, 0x0B, 0x00, 0x03, 0x00, 0x89, 0x00, 0x00, 0x4A, 0x15, 0x38, 0x00, 0x33, 0xE8}
result := egts.Package{}
state, err := result.Decode(pkg)
if err != nil {
log.Fatal(err)
}
log.Println("State: ", state)
log.Println("Package: ", result)
}
Store plugins
That create a new plugin you must implementation Connector interface:
type Connector interface {
// setup store connection
Init(map[string]string) error
// save to store method
Save(interface{ ToBytes() ([]byte, error) }) error
// close connection with store
Close() error
}
All plugins available in store folder.
