step S107: acquiring the times of unsuccessful uploading of the transaction data which is not uploaded;
step S108: judging whether the number of times of unsuccessful uploading is equal to one;
step S109: when the number of unsuccessful uploads is equal to one, after t1 (e.g., 3 minutes), the transaction data packet and the data upload code are sent to the cloud server, and this time, the transaction data packet and the data upload code are uploaded for the second time. After the transaction data packet and the uploading code are not uploaded successfully for the first time, the transaction data packet and the uploading code are uploaded to the cloud server again; after step S108, continuing to execute step S105, namely, continuing to determine whether the first verification code sent by the cloud server is received, and after receiving the first verification code sent by the cloud server, continuing to execute step S106, namely, marking the transaction data which is not uploaded as uploaded data; that is to say, the transaction data that is not uploaded is uploaded twice and then successfully uploaded to the cloud server.

step S1011: when the number of unsuccessful uploads is equal to two, the transaction data packet and the data upload code are uploaded to the cloud server after t2 (for example, 5 minutes), which is the third time of uploading the transaction data packet and the data upload code. After the transaction data packet and the uploading code are not uploaded successfully for the first time and the second time, the transaction data packet and the uploading code are uploaded to the cloud server again; after step S1011, continuing to execute step S105, namely, continuing to determine whether the first verification code sent by the cloud server is received, and after receiving the first verification code sent by the cloud server, continuing to execute step S106, namely, marking the transaction data which is not uploaded as uploaded data; that is to say, the transaction data that is not uploaded is uploaded three times and then successfully uploaded to the cloud server. When the first verification code sent by the cloud server is not received, namely the transaction data packet is uploaded for the third time and the uploading code is not successfully uploaded to the cloud server, the following steps are executed:

step S1012: when the number of times of unsuccessful uploading is not equal to two, judging whether the number of times of unsuccessful uploading is equal to three or not;
step S1013: when the number of unsuccessful uploads is equal to three, the transaction data packet and the data upload code are uploaded to the cloud server after t3 (for example, 30 minutes), which is the fourth time of uploading the transaction data packet and the data upload code. After the transaction data packet and the uploading code are not uploaded successfully for the first time, the second time and the third time, the transaction data packet and the uploading code are uploaded to the cloud server again; after step S1013, continuing to execute step S105, namely, continuing to determine whether the first verification code sent by the cloud server is received, and after receiving the first verification code sent by the cloud server, continuing to execute step S106, namely, marking the transaction data which is not uploaded as uploaded data; that is, the transaction data that is not uploaded is uploaded to the cloud server successfully after being uploaded four times. When the first verification code sent by the cloud server is not received, namely the transaction data packet is uploaded for the fourth time and the uploading code is not successfully uploaded to the cloud server, the following steps are executed:
step S107: acquiring the times of unsuccessful uploading of the transaction data which is not uploaded;
step S108: judging whether the number of times of unsuccessful uploading is equal to one;

According to the embodiment of the invention, when the transaction data which is not uploaded for the first time is not successfully uploaded, the transaction data which is not uploaded is carried out for multiple times, so that all the transaction data of the electronic scale can be further ensured to be uploaded to the cloud server, and the probability of data loss or loss is reduced.
Preferably, the time t1 is less than the time t2, the time t2 is much less than the time t3, there is a time interval between each upload of transaction data that is not uploaded, and a buffer time is given to the electronic scale and the cloud service end, so that the probability of successful upload is increased.
As is well known, for a merchant using an electronic scale, transaction data of each day is countless, and if all transaction data of an electronic scale are stored in a storage system of the electronic scale, the pressure of the storage system is increased and the operation speed of the electronic scale is reduced, so in an embodiment of the present invention, as shown in fig. 3, no matter how many times the transaction data that is not uploaded passes, the transaction data that is not uploaded is successfully uploaded to a cloud server, and after the transaction data that is not uploaded is marked as uploaded data in step S106, the method for intelligently transmitting electronic scales based on the internet of things further includes:
step S1015: acquiring data uploading time of the uploaded data, namely data uploading time T1 marked as the uploaded data;
step S1016: determining whether a second time interval between the data uploading time T1 and the current time T2 is greater than or equal to a second preset time interval (e.g., the second preset time interval is 1 hour); and
step S1017: and deleting the uploaded data when a second time interval | T2-T1| of the data uploading time and the current time is greater than or equal to a second preset time interval, such as | T2-T1| > 30 days.
When the second time interval | T2-T1| of the data uploading time and the current time is smaller than a second preset time interval, for example, | T2-T1| > 30 days, the transaction data which are not uploaded are not processed, the transaction data are returned to be recorded and stored, and the uploaded data are further accumulated.
The second predetermined time interval may be designed according to actual transaction conditions, for example, when the daily transaction amount is small, the second predetermined time interval may be designed to be 30 days or even longer. When the daily transaction amount is large, the second preset time interval may be designed to be 10 days or even shorter.
According to the embodiment of the invention, by clearing the transaction data uploaded to the cloud server, the storage pressure of the electronic scale is reduced and the running speed of the electronic scale is increased on the premise of not losing the transaction data.
In practical application of the electronic scale, the transaction data that is not uploaded is uploaded to the cloud server, and in order to reduce the number of uploading times, in an embodiment of the present invention, the transaction data may be stored first, and the transaction data that is not uploaded is uploaded to the cloud server only when the transaction data meets a certain condition, that is, as shown in fig. 4, step S102 further includes:
step S1021: acquiring the quantity of the transaction data which are not uploaded, namely the quantity of the transaction data which are not uploaded and currently stored in the electronic scale, for example, the currently stored transaction data which are not uploaded in the electronic scale are 10 pens;
step S1022: judging whether the quantity of the transaction data which is not uploaded is more than one;
