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
