The working principle of the technical scheme is as follows: firstly, after receiving version difference information fed back by each user terminal, the remote server sorts the user terminals according to the sequence from small to large of the version orders of the difference between the firmware version information of the user terminal and the latest firmware version information, so as to form a version difference data set; each element in the version difference data set is a value corresponding to a version number level of a phase difference between the current firmware version information of the user terminal and the latest firmware version information; and then, according to the numerical value corresponding to the version number of the difference between the current firmware version information and the latest firmware version information of the user terminal, acquiring the upgrade division index of the user terminal through an index acquisition model.
The technical scheme has the effects that: the demarcation standard of the user terminal upgrading batch division is carried out by the mode of setting the user terminal upgrading division index, so that the rationality of the user terminal upgrading batch division and the matching with the actual firmware version condition of the user terminal can be effectively improved. Meanwhile, the batch division efficiency of the user terminal can be effectively improved. On the other hand, after the user terminal upgrading division index is obtained through the formula, the rationality and balance of the number proportion of the first upgrading users and the second upgrading users can be effectively improved, so that the problem that the OTA upgrading efficiency is reduced due to broadband congestion cannot be caused by the number of the terminals upgraded by each user terminal, the upgrading batch of the user terminal can be accurately divided according to the actual information of the firmware version of the user terminal, and the accuracy of judging the OTA upgrading sequence of the user terminal is improved. Meanwhile, the first upgrade users and the second upgrade users are divided according to the values corresponding to the version number levels of the difference between the current firmware version information and the latest firmware version information, the number of the first upgrade users and the second upgrade users can be controlled, and under the condition of improving the rationality and balance of the number proportion of the first upgrade users and the second upgrade users, the user terminal of each batch can carry out quick version upgrade, and the tab improves the OTA upgrade efficiency.
According to one embodiment of the invention, the number of the first batch of upgrading user terminals and the number of the second batch of upgrading users are determined according to the user terminal upgrading division index, and batch upgrading is carried out for the corresponding user terminals, and the method comprises the following steps:
S401, classifying the user terminals of which the values corresponding to the version number levels of the difference between the current firmware version information and the latest firmware version information of the user terminals are smaller than or equal to the user terminal upgrading division index into a first upgrading user list, and arranging the user terminals according to the sequence of the difference between the current firmware version information and the latest firmware version information of the user terminals;
s402, classifying the user terminals with the values corresponding to the version number levels of the difference between the firmware version information of the user terminal and the latest firmware version information being greater than the upgrade division index of the user terminals into a second upgrade user list;
S403, comparing the number of user terminals in the list of the first upgrading users with a preset first upgrading user number threshold, and when the number of user terminals in the list of the first upgrading users is smaller than the first upgrading user number threshold, or the number of user terminals in the list of the first upgrading users exceeds the first upgrading user number threshold and does not exceed a first difference value, directly sending an OTA upgrading packet downloading instruction to each user terminal in the list of the first upgrading user, and allowing each user terminal in the list of the first upgrading user to download the OTA upgrading packet; the first difference value is obtained by the following formula:
Wherein C represents a first difference value; w represents the total number of all user terminals that need to be upgraded; w 1 represents the number of user terminals in the list of the current first upgrade user; w 2 represents the number of user terminals in the current list of the second set of upgrade users; c 0 does not represent a preset first upgrade user quantity threshold; r represents an adjustment coefficient, and the value range of r is 0.47-0.53, preferably 0.49;
S404, when the number of user terminals in the list of the first upgrading users exceeds the threshold value of the number of the first upgrading users by more than a first difference value, determining the number difference H between the number of the user terminals in the list of the first upgrading users and the first difference value, and adjusting the last H user terminals in the list of the first upgrading users to a second upgrading user list, and arranging the user terminals in sequence before all original user names of the second upgrading user list;
S405, when each user terminal in the first upgrading user list receives an OTA upgrading packet downloading instruction, if the OTA upgrading packet is not downloaded in a preset specified time period, the remote server disconnects an OTA upgrading packet downloading link with the user terminal; and placing the user terminal at the tail of a second upgrading user list, adjusting the first h user terminals in the second upgrading user list to a first upgrading user list, sending an OTA upgrading packet downloading instruction, and allowing each user terminal in the first upgrading user list to download the OTA upgrading packet, wherein h is the number of user terminals in the first upgrading user list, which do not download the OTA upgrading packet in a specified time.
The technical scheme has the effects that: when the number of the firmware versions of the user terminals is more, and the difference of the values corresponding to the version number levels of the difference between the current firmware version of the user terminal and the latest firmware version is less, the number of the first upgrade users is more when the first upgrade users and the second upgrade users are classified according to the user terminal upgrade classification index, the rationality and the balance of the number proportion of the first upgrade users and the second upgrade users are reduced, so that the upgrade consumption time of the first upgrade users is increased due to the number more, the OTA upgrade waiting time of the second upgrade users is prolonged, and the OTA upgrade efficiency is further reduced. Therefore, the number of the user terminals of the first upgrading users can be effectively and quickly adjusted under the condition of setting the first upgrading user number threshold value and the first difference value. The number of the adjusted first upgrading users and the second upgrading users is restored to the reasonability and balance of the quantity proportion again, and the high-efficiency OTA upgrading of the first upgrading users and the second upgrading users is ensured. Meanwhile, the first difference value obtained through the formula can be effectively adjusted by combining the actual number of the current first upgrade users and the actual number of the second upgrade users, so that the user number adjustment caused by each OTA firmware upgrade can be highly matched with the total number of the current actual user terminals and the number of the first upgrade users and the second upgrade users, and the accuracy and the rationality of the user terminal number adjustment of the first upgrade users and the second upgrade users are effectively improved.

Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
