Technical Field
The invention relates to a self-service vending machine technology, in particular to an improved method based on self-service vending system data uploading.
Background
As society develops, self-service vending systems have become popular in cities. In the existing self-service vending system, under the offline condition of the vending machine, transaction data such as vending information generated by the vending machine cannot be uploaded in a network communication mode, and the current solution is that at the end of an operation day, a worker copies and uploads transaction records to vending equipment by using a mobile storage device. Problems that easily arise with this approach are: manual operation is easy to generate errors, and data can be mistakenly and leaked; if the network of the equipment is interrupted within a period of time and then the network connection is recovered, the data within the interruption time is not uploaded in time, and the real-time performance of the data is influenced.

Detailed Description
The technical scheme of the invention is described in detail in the following with reference to the accompanying drawings.
The invention relates to an improved method based on self-service vending system data uploading, a flow chart in the specific implementation process of the improved method is shown in a figure 1, wherein the method comprises the following steps:
step 1, establishing data connection between a self-service vending machine and a target host;
step 2, when the self-service vending machine and the target host machine carry out data transmission, judging the current state of the self-service vending machine, if the self-service vending machine is judged to be in an online state, processing the data transmitted by the self-service vending machine and storing the data as an online data file by the target host machine, and if the self-service vending machine is judged to be in an offline state, storing the data as an offline data file by the self-service vending machine;
step 3, when the self-service vending machine is in an off-line state, if the data connection with the target host is not recovered, the self-service vending machine stores the data as an off-line data file, and if the data connection with the target host is recovered, the step 4 is carried out;
and 4, judging whether the target self-service vending machine has the offline data files or not, if so, classifying the offline data files and transmitting the offline data files to the target host, otherwise, transmitting the real-time online data to the target host.
In the above method, in step 2, when the current state of the self-service vending machine is judged, the method includes: the self-service vending machine sends data to the target host, the target host receives and processes the data and judges whether the processing is successful or not, if the processing is successful, the received data is stored into an online data file and sends a confirmation character to the self-service vending machine, if the processing is failed, the self-service vending machine retries, if the processing is still failed after retrying corresponding times, the self-service vending machine enters an offline state, the target host does not send the confirmation character, and the self-service vending machine stores the data into the offline data file. The number of retries is preferably five, the number of retries is the number of processing failures, each processing failure requires the self-service vending machine to send data to the target host, and the target host receives and processes the data once.
In practical application, the principle of the improved method based on the self-service vending system data uploading can be combined by a data backup method and an automatic data detection uploading method.
The above mentioned data backup method is similar to the TCP timeout retransmission mechanism, and is different from the commonly used backup method. The conventional backup only simply copies the file, only simply adds the file, and places where duplication and conflict are possible exist, so that the reliability and the safety are not particularly high. The backup method mentioned here adopts reliable message data transmission technology, so that the reliability and the safety of the backup file are greatly improved, and the purpose of reliable message transmission is to ensure that the message is transmitted to the other side without loss, repetition and conflict.
The current state of the self-service vending machine needs to be judged during message transmission, and an offline state judgment mechanism needs to be used in the judgment process.
The existing self-service vending system offline determines that once the connection is disconnected, the self-service vending machine will try to establish contact with the central host machine until the connection is reestablished, and data in the process cannot be automatically stored. The existing offline judgment mechanism takes whether data is received as a reference to judge the state online and offline, and does not react immediately after the judgment.
The offline state judgment mechanism adopted by the invention takes whether ACK is received as a reference, and stores the offline data immediately after the judgment. The specific process comprises the steps of firstly sending data to a target host, processing the data by the target host, storing a received data file if the processing is successful, and sending ACK (acknowledgement character); and if the processing fails, retrying, and after the retrying is carried out for five times, entering an offline mode, not sending an ACK (acknowledgement character), and storing the data as an offline data file.
The automatic detection uploading method is to detect the system immediately after the network is recovered, read and detect the off-line data again, and then upload the off-line data to the target host again. The existing data detection uploading method only packs and sends data to a central host, and the data received by the host is not classified and needs to be classified and sorted manually.
Different from the traditional data checking and uploading method, the data are firstly identified and classified by adopting an identification technology in the process, the data packet which receives the ACK is identified as online data, and the data which does not receive the ACK is identified as offline data. When data identification is carried out, semantic definition needs to be carried out on the data, and the data is classified. And then the offline data and the online data are respectively packaged and then uploaded, so that the time for data transmission is greatly saved. When uploading, the host receives the classified data, and then analyzes the two data packets by using an analysis technology according to whether the ACK is received, so that the relevant data collection and statistics are facilitated, and the working efficiency is greatly improved.
Therefore, the data backup method can timely backup the system into an offline file when the system is offline, and the backed-up data has safety and reliability. The automatic data detection and uploading method can classify and upload offline data when connection is recovered. The two methods are combined, so that the full-process autonomous system butt joint of automatic off-line data backup and automatic on-line data classified uploading can be realized, manual intervention is not needed, and the problems of data loss, data incompleteness, low accuracy, incapability of automatic synchronization of data after network recovery and the like in an off-line condition can be solved.
