the temperature detector 1 is connected with a temperature acquisition card of the singlechip 2.
The single chip microcomputer sends the events to the management server in a mode that the single chip microcomputer independently encapsulates each event into an information message and then sends the information message to the management server;
the single chip microcomputer comprises a transmission program and a control program;
here:
the transfer program is used for transferring the information message to the management server;
the control program is used for adding a transmission guide sign in the information message if the transmission program does not obtain the response message of the management server to the information message within a set time length, wherein the transmission guide sign is used for indicating the transmission mode of the information message;
the transfer program is also used for performing re-transfer on the information message by means of the transfer guide mark additionally arranged in the control program.
Here, the set time length can be determined by a tolerance threshold of a longest time length from when the single chip microcomputer first transmits the information message to the management server until the single chip microcomputer obtains a response message that the management server transmits the information message to the single chip microcomputer. The tolerance threshold value is the time which can be reached after the longest time length from the first time when the single chip microcomputer transmits the information message to the management server until the single chip microcomputer obtains the response message which is transmitted by the management server to the single chip microcomputer and obtains the information message is added with 5 seconds. The final time of the set duration is below that time.
The manipulation program can be used to:
determining that the information message is not required to be retransmitted by means of a tolerance threshold value of the longest duration from the time when the single chip microcomputer transmits the information message to the management server for the first time until the single chip microcomputer obtains a response message which is transmitted by the management server to the single chip microcomputer and obtains the information message:

The number of times in the number mark of the number of times of transmission can be used for transmitting the information message again by using another mode;
the performing retransmission of the information packet by the number of times in the number of times transmitted flag may further include:
if the number of times of transmission is one, selecting an information link to transmit the information message again;
if the number of times of transmission is more than one, the information message is transmitted again on a plurality of information links.
The method for information message transmission can further comprise:
determining that the information message is not required to be retransmitted by means of a tolerance threshold value of the longest duration from the time when the single chip microcomputer transmits the information message to the management server for the first time until the single chip microcomputer obtains a response message which is transmitted by the management server to the single chip microcomputer and obtains the information message:
if the final time of the time length required by the advance estimation for transmitting the information message to the management server again is lower than the tolerance threshold value of the longest time length, a transmission guide mark is additionally arranged in the information message;
selecting a corresponding information link which can transmit the information message to the management server again and has the estimated time required in advance and the final time lower than the tolerance threshold value of the longest time to perform retransmission by means of the tolerance threshold value of the longest time;
and if the final time of the time length required by the advance estimation for retransmitting the information message to the management server is not lower than the tolerance threshold value of the longest time length, the task of retransmitting the information message is not executed any more.
The structure of the single chip microcomputer for sending the information message to the management server is divided into three stages: an encapsulation stage, a transport stage, and a link stage, where,
and (3) packaging stage: independently encapsulating each event into an information message;
a transmission stage: the management server identifies the information message obtained by the singlechip, namely transmits a response message to the singlechip; the single chip microcomputer executes sequencing on the transmitted information messages in a serial number marking mode, starts timing when transmitting the information messages and executes retransmission on the information messages when the information messages need to be retransmitted;
and (3) link level: one or several information links are selected to transmit the information message delivered by the transmission stage to the management server.
During the transmission of the information message, if the single chip microcomputer transmits the information message to the management server through an information link for the first time and does not obtain the response message of the management server to the information message within the set time length for the first time, the transmission level of the single chip microcomputer adds a transmission guide mark for indicating the transmission mode of the information message in the information message and transmits the transmission guide mark to the link level; after obtaining the transfer guide mark, the link level can perform re-transfer on the information packet by means of the transfer guide mark.
It is also possible to integrate the encapsulation stage with the delivery stage, only to ensure that the link stage can obtain information messages, whether they need to be delivered again.
Here, the tolerance threshold is set to be K, which is the time that can be reached after the longest time that the single chip microcomputer transmits the information message to the management server for the first time until the single chip microcomputer obtains a response message that the management server transmits the information message to the single chip microcomputer and 5 seconds later, and the final time that the single chip microcomputer transmits the information message to the management server for the first time until the single chip microcomputer obtains the longest time that the single chip microcomputer obtains the response message that the management server transmits the information message to the single chip microcomputer is L, where K is greater than L, then retransmission is performed on the information message when the time of waiting for the response message is greater than L, and thus the retransmission time is limited between 0 and the value obtained by subtracting L from K, so as to ensure that the information message obtained by the management server is still fast and efficient after retransmission.
Thus, the performance of fast, efficient and correct message transmission can be obtained when occasional message loss and blocking occurs in a short period of time on an information link.
And the single chip microcomputer has little benefit in the aspect of utilizing the efficiency of the information links compared with the performance of improving the correctness of transmission by only transmitting the information message through one information link and combining a plurality of information links.
Also, in contrast to the way in which test messages for testing the information link are transmitted between the single-chip and the management server when packaged as an information message, the single-chip has better adaptability in this way (no test messages have to be used between the single-chip and the management server).
The invention has the beneficial effects that:
and executing retransmission of the information message by means of a mode of activating the singlechip, and if the transmission program does not obtain a response message of the management server to the information message within a set time length, executing retransmission of the information message by adding a transmission guide mark for indicating the transmission mode of the information message in the information message transmitted to the management server. Thus, when the sporadic information message of a short period of time is lost and blocked on an information link, the information link for information message transmission can be quickly changed by the transmission guide mark, so that the message transmission can be fast, efficient and correct.
