The Bluetooth-based intelligent water meter program upgrading device according to claim 5, characterized in that: the specific method for checking and analyzing the code returning instruction is as follows: judging whether the code returning instruction is lost or correct: if the code returning instruction is lost or incorrect, triggering a retransmission mechanism, returning to resend the upgrading request instruction, and prompting the user that the upgrading fails when the number of times of triggering the retransmission mechanism exceeds three times; if the code returning instruction is correct, judging the code returning instruction type, wherein the code returning instruction type comprises an upgrading request instruction type, a block upgrading packet instruction type and an upgrading ending instruction type; when the code returning instruction type is the request upgrading instruction type, analyzing an upgrading mark through the code returning entity data, and judging whether the upgrading mark needs to be upgraded or not; if the upgrading mark is that upgrading is not needed, prompting a description of the condition that upgrading cannot be carried out; if the upgrading mark is in need of upgrading, analyzing information of an upgrading packet number, an upgrading packet length and a target version number through the code returning entity data, calculating the total packet number according to the total byte number and the upgrading packet length of a local cache, sending a block upgrading instruction with the upgrading packet number, the upgrading packet length and upgrading packet data to the intelligent water meter, receiving a next code returning instruction, and checking and analyzing the code returning instruction; when the code returning instruction type is a blocked upgrading packet instruction type, analyzing information of an upgrading packet number, an upgrading packet length and a target version number through the code returning entity data, sending a blocked upgrading instruction with the upgrading packet number, the upgrading packet length and upgrading packet data to the intelligent water meter, receiving a next code returning instruction, and verifying and analyzing the code returning instruction; when the code returning instruction type is an upgrading ending instruction type, analyzing an upgrading completion mark through a code returning entity number, and when the upgrading completion mark is upgrading success, prompting that the upgrading is successful by a mobile phone APP and updating a user interface; when the upgrade completion mark is upgrade failure, the mobile phone APP prompts the upgrade failure; and repeating the steps until the number of the upgrade package is the same as the total package number, and finishing the program upgrade when the code returning instruction type is the upgrade ending instruction type.
7. An electronic device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, characterized in that the processor implements the method according to any of claims 1 to 3 when executing the program.
8. A computer-readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out the method according to any one of claims 1 to 3.
