Initialize the initialization before being broadly divided into system reset initialization and starting self study.Reset initialization is being only
System generation just can perform when restarting, and will not restart easily in system properly functioning period.When system reset initializes,
The variable of the successful communication interface of record last time communication defined in internal memory is zeroed out.Initializing before self study is often
Secondary all can perform once when carrying out self study, and system properly functioning period can according to archives situation perform repeatedly stipulations from
Study.Initialization before self study, mainly resets some timer variable, and the last communication of internal memory record is the most logical
Communication interface variable keeps constant.When the most only carrying out stipulations self study after system reboot first on record defined in internal memory one
The variate-value of the successful communication interface of secondary communication can be just zero, and when the most again carrying out self study, this variate-value can keep last
Secondary value is constant.
Step 2, communication interface select
2-1, judge that the last time of the internal memory record successful communication interface that communicates is whether effective, i.e. whether judge communication interface
Communication interface code name to transducer；If effectively, then prioritizing selection communicated successful communication interface as souning out communication in advance last time
Interface；If invalid, then the communication interface that one priority of selection is the highest is as souning out communication interface in advance；If being successfully selected prerun
The effective communication interface visiting communication then enters step 3；Choose the pre-effective communication interface souning out communication if unsuccessful, produce
Sound out unsuccessfully alarm and enter step 6；
In step one, communication interfaces all to transducer carry out connecing by 1 to N number consecutively, i.e. communication according to data value size
Mouth code name, the later stage is all to directly select data value size as corresponding communication interface when selecting.
Owing to reset initialization only just can perform when system produces and restarts, the most only enter first after system reboot
The situation that variate-value is zero of the last successful communication interface that communicates of the record defined in internal memory is just there will be during row self study,
As long as carrying out learning success mistake during self study in the case of remaining, this variate-value would not be zero.If this value is zero, then it is assumed that should
Communication interface is invalid, carries out communication interface selection according to judgment criterion time invalid.

Order from small to large selects；If there is not the communication the same with the priority of last exploration communication failure communication interface
Interface, then select the communication interface of the next priority of last time exploration communication failure communication interface priority to sound out as pre-
Communication interface, if the communication interface of next priority has multiple, enters also according to communication interface code name order from small to large
Row selects；If being successfully selected the pre-effective communication interface souning out communication, enter step 3；Pre-exploration is chosen if unsuccessful
The effective communication interface of communication then produces sounds out unsuccessfully alarm entrance step 6；
Step 3, framing, transmission
According to souning out communication interface determined by step 2 in advance, send data communication；
Step 4, receipts frame, parsing
According to souning out communication interface determined by step 2 in advance, the due-in frame such as carry out, if receiving within the waiting time of regulation
Frame success, then it is assumed that current pre-communication interface of souning out is soundd out successfully, the last time successful communication of communication recorded in internal memory connects
Mouth changes to currently be soundd out the successful communication interface of communication, enters step 5；If not receiving frame within the waiting time of regulation to become
Merit, then it is assumed that Current communications interface is soundd out unsuccessfully, enters the 2-2 of step 2；
Step 5, archives update
For communication successful water, air and heat table, table meter address and the corresponding communication interface of this table are deposited in parameter
Storage area carries out unifying storage；Later stage interface convertor carries out standard when carrying out and periodically checking meter according to stored communication interface
Really, communicate efficiently.
Step 6, return result
If this step is to be entered by step 5, then it is assumed that currently by the table end communication interface of communication the match is successful, return
Pass flag；If this step is to be entered by step 2, then it is assumed that current water/gas/hotlist communication interface learns unsuccessfully, returns coupling
Fail flag.
The specifically chosen principle of communication interface is as follows:
(1) when carrying out communication interface and selecting, the last successful communication interface that communicates can be paid the utmost attention to, the most often communicate
Success the most once, will record this time in internal memory and communicate successful communication interface；
(2) if the last time of internal memory record communicates, successful communication interface is invalid, or the last time used communicates successfully
Communication interface carry out failure when communication interface is soundd out, then lead to according to the priority of each communication interface in communication interface storehouse
Communication interface selects, sounds out；
(3) if during the corresponding multiple communication interface of selected priority, then according to communication interface code name order from small to large
Select a pre-exploration communication interface.
