Parsed, obtained the analysis mode of the message.
As prior art is present when message format changes, personnel are needed to participate in otherwise causing nothing
Method carries out the problem of correct parsing to message.
The present invention provides a solution, when making message format change, can be automatically according to current
Message format switches analysis mode, it is not necessary to the participation of personnel, and avoids because message format occurs
Change and cause the problem of message interior packet parsing failure for a period of time.
With reference to Fig. 1, it is message parsing method first embodiment of the present invention, the message parsing method includes：
Step S101, when received between synchronizer send message when, according to current message type mark
The corresponding analysis mode in note position is parsed to the message；
This embodiment scheme is mainly used in TOD message formats, is also not necessarily limited to certainly other reports for needing parsing
Literary form, the present embodiment are illustrated with TOD message formats.
First, packet parsing system is opened, and packet parsing system is communicated with time synchronism equipment, starts to connect
Receive the message from time synchronism equipment.
When the message that the time synchronism equipment sends is received, deposit in reading current message type mark position
The analysis mode of storage, parses to the message according to the analysis mode, the type of message labelling
Position correspondence at least one packet parsing mode.
By taking TOD messages as an example, comprise the following steps that：
First, packet parsing system is opened, to the communication before packet parsing system and time synchronism equipment
Interface is monitored, when the interface is to data, the packet parsing system start receive from
The message of time synchronism equipment；
Then, when received between synchronizer send message when, according to current message type mark position
Corresponding analysis mode is parsed to the message.
Wherein, for TOD messages, 1PPS (1Pulse Per Second, pulse per second (PPS))+TOD messages
Form is the more commonly used, and 1PPS+TOD is the time synchronized interface of short-distance transmission, carries gps time,
Leapsecond (leap second) information and UTC (Universal Time Coordinated, Coordinated Universal Time(UTC))
There are multiple format time, 1PPS+TOD interfaces：GPS general NMEA (National Marine
Electronics Association, National Marine Electronics association) form, DCLS (Data Collection
And Location System, data collection and position system) form, China Mobile's precise synchronization
1PPS+TOD forms and Chinese Beidou satellite navigation system form etc..Generally, a kind of packet parsing mode
A kind of message format of correspondence, i.e., a kind of analysis mode parse a kind of message of message format, if message format
It is not corresponding with analysis mode, then cause packet parsing to fail.
When synchronizer sends message, the possible message for sending different-format, and the message of different-format
Different analysis modes are needed to be parsed, therefore, after message format switches, if the message after switching
Form cannot be matched with current analysis mode, then cause parsing failure.
Step S102, during the packet parsing, detects whether the packet parsing is overtime；
