Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in the figure, the invention comprises the following steps: a. the device transmits data to the Internet of things platform through a southbound interface based on 4G/5G/NBIOT and other networks, and the Internet of things platform receives original data transmitted by the device and transmits the original data to the application system through a northbound interface; b. the application system receives original data and writes the original data into a message queue of the application system; c. analyzing and abnormal processing are carried out on the original data in the message queue through a consumption process, and packet loss information is obtained; d. the application system transmits a retransmission command to the Internet of things platform according to the packet loss information; e. and the Internet of things platform transmits the retransmission command to the appointed equipment. According to the invention, when the application system detects packet loss, the command is automatically issued to the Internet of things platform, the Internet of things platform forwards the command to the designated equipment, and the equipment retransmits the data which is failed to be transmitted after receiving the command, so that the processing time is more accurate, the packet loss processing effect can be enhanced, the accuracy and the integrity of data transmission are ensured, and the data transmission efficiency and quality are improved.
According to the above technical solution, preferably, the raw data includes sensor data, an equipment attribution item ID, an equipment site ID, and an ID of the current communication session.
According to the above technical solution, preferably, step c includes:
(1) and acquiring original data from the message queue, and analyzing a data header and a packet body.
(2) And judging whether data are lost or not. In this step, the consumption process determines whether packet loss exists by combining the current communication session ID in the cache, and the specific determination principle is as follows: and the session IDs are sorted from small to large, the range is 0-65536, the session ID is reset to 0 after exceeding 65536, the session ID is updated once when data is reported each time, and if the difference between the session ID of the data reported next time and the last session ID cached in the system is more than 1, the packet drop is considered to exist. Such as: and if the session ID sequence 1,2,3,5 is determined that the packet with the session ID of 4 is lost, the station information with the session ID of 4 is written into the database, the retransmission process reads the record and then sends a retransmission command to the IOT platform, the IOT platform sends the command to the equipment, and the equipment reports the retransmission data after receiving the command.
(3) And if no data is lost, writing the normal data into the database, namely if no packet loss exists, analyzing the data, writing the data into the database, updating the session ID, and continuously consuming the next piece of data.
(4) And if the data loss exists, performing packet loss marking processing. The packet loss marking processing comprises the following steps: and writing the packet loss data with the retransmission identifier into a database and a cache. After the consumption process judges that the packet is lost, the item ID, the site ID and the session ID of the lost data are written into a retransmission table of the database, and when the data are lost, retransmission identification information is written into the database and the cache, so that after the retransmission is successful, the cache identification is deleted, and the state of the retransmission record inserted into the database is updated.
According to the above technical solution, preferably, step d includes:
(1) and acquiring packet loss data from the database.
(2) And generating a retransmission command according to the packet loss data, and transmitting the retransmission command to the Internet of things platform.
(3) And judging whether the retransmission command is transmitted successfully or not. The method for determining whether the retransmission command is successfully transmitted in this example is as follows: the telecommunication IOT platform is provided with a callback mechanism, and if command retransmission is successful and failed, corresponding callback actions are triggered. If the retransmission command is successfully issued, a retransmission success flag is set, the information with the cache identification in the cache is deleted, and the state of the retransmission record inserted into the database is also updated. And if the retransmission command fails to be issued, deleting the recorded cache information, continuously processing the next lost data, after one iteration cycle, issuing the retransmission command to the data packet which is not successfully retransmitted again, and if the retransmission still fails after N times of attempts, giving up the retransmission.
