11.4.6 Standard Format Description

The following is an EBNF syntax of a new record format that we have

developed that we believe is more digestible than the pseudo-SQL syntax that

is in the original protocol:

outputRec = recordHeader { “,” fieldName “,” fieldType “,” fieldValue } “\r\n”.

recordHeader = stationName “,” tableName “,” timeStamp “,” recNo.

FieldName = string.

FieldType = (“TIMESTAMP” | decimalType | “FLOAT” | “INTEGER” | varCharType ).

FieldValue = string.

StationName = string.

TableName = string.

TimeStamp = “\”“ year “–” month “–” day “ “ hour “:” minute “:” second “\”“.

RecNo = “\”“ digit {digit} “\”“.

Year = 4(digit).

Month = 2(digit). ; 0 < month <= 12

day = 2(digit). ; 0 < day <= 31

hour = 2(digit). ; 0 <= hour < 60

minute = 2(digit). ; 0 <= minute < 60

second = 2(digit) [“.”] {digit}. ; 0.0 <= second < 60.0

string = “\”“ {ascii_character} “\”“.

DecimalType = “DECIMAL(“ digit [digit] “,” digit [digit] “)”.

VarCharType = “VARCHAR(“ digit {digit} “)”.

Within a string, quotation marks and back slash characters will be quoted with

a backslash character.

The sample record from the original protocol would have the following format

under this new syntax:

“Lgr”,”Sec15”,”1993-12-08 15:02:00”,”123456”,”Battery_V”,”FLOAT”,

“13.5”,”Temp”,”FLOAT”,”72.123” CRLF

The acknowledgment message is the same as for the RTMS format. The

acknowledgment for the above record would be:

Lgr,Sec15,123456

11-21

1 2 ... 444 445 446 447 448 449 450 451 452 453 454 ... 579 580
