The present invention also provides a kind of communication means, for communicating by letter between optical fiber temperature-measurement main frame and temperature-sensitive data general-purpose server, comprises the following steps:
Step S100, temperature-sensitive data general-purpose server receives the request of data of optical fiber temperature-measurement main frame, and receiving data packets also deposits the end of storing chained list in;
Step S200, reads article one data message in storage chained list, and data message is carried out to verification;
Step S300, the message that verification is passed through is resolved and is stored;
Step S400, temperature-sensitive data general-purpose server sends reply data message to optical fiber temperature-measurement main frame.
In step S100, after system starts, when communication module 101 is received the request of data of optical fiber temperature-measurement main frame, temperature-sensitive data general-purpose server 100 receives the data message of optical fiber temperature-measurement main frame, in storage chained list end, inserts a new data message of storage.
Further, in described step S200, correlation function in calling data correction verification module 103, carries out verification according to default agreement to data message, as heading, tail tag knowledge, length, check digit etc., if verification is unsuccessful, represent that message is invalid, should abandon and not deal with, directly delete the data message of working as pre-treatment in storage chained list, and send verification failure reply data message to optical fiber temperature-measurement main frame, then continue to process next message data in storage chained list.Further, when optical fiber temperature-measurement main frame is received verification failure message, can do data re-transmitting and process.If verification succeeds, carries out dissection process to data message.
In described step S300, the related resolution function parsing of calling in parsing module 104 obtains data storage node fruit, and the type of message that parsing module 104 obtains according to parsing (temperature data, partition information etc.) leaves in respectively in subclass corresponding in result class.Memory module 105, according to type of message, is called respectively corresponding data loading sub-interface the data after resolving is saved in database.
Preferably, in described step S300, the method that message is resolved is: according to the type of message in default message format, if 0AH resolves to temperature data message; If 1AH, resolves to temperature warning data message; If 1BH, resolves to event of failure data message; If 2AH, resolves to facility information configuration data message; If 2BH, resolves to channel information configuration data message; If 2CH, resolves to partition information configuration data message; When if current data message is temperature alarming data message or event of failure data message, temperature-sensitive data general-purpose server sends a warning message.
Further, in described step S400, after the complete data message of temperature-sensitive data general-purpose server process, to optical fiber temperature-measurement main frame, send reply data message, and delete data and store current data message of finishing dealing with in chained list, temperature-sensitive data general-purpose server is followed next data message in deal with data storage chained list simultaneously, and just the end of now data storage chained list deposits again a new data message in.Result in described reply data message comprises that 00H-claim frame all processes that failure, 01H-claim frame are all processed successfully, the section processes success of 02H-claim frame or the invalid claim frame of FFH-.
In above-described communication process, when accessing or connect the database in temperature-sensitive data general-purpose server, by house dog 106, can realize the mechanism of reconnecting, as: during the current request of data of receiving optical fiber temperature-measurement main frame, when if database house dog thread is dormancy shape or halted state, attempt whether can connecting database, if success is exited; If failure, log-on data storehouse house dog reconnects thread, allows it enter operating state.When reaching the reconnecting after interval time of setting, automatically attempt connection data storehouse, if success stops thread and finishes.
The above technical scheme, adopt the temperature-sensitive data general-purpose server of default communication protocol, can with arbitrary optical fiber temperature-measurement main-machine communication in industry, and ambient systems can be realized the access of optical fiber temperature-measurement data and warning information are received by this server, thereby efficiently solves the problem that cost is high, efficiency is low and difficult in maintenance because developer component interface or intermediate server cause again.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
