The refrigerator production line includes a conveying device for conveying an assembled refrigerator; a scanning device for scanning and confirming an identification code of the assembled refrigerator and an address code of a communication module in the assembled refrigerator; and a local server for saving the identification code of the assembled refrigerator and the address code of the communication module and further acquiring, in response to a firmware upgrade request, a firmware upgrading package for the assembled refrigerator that corresponds to the identification code. After the assembled refrigerator is powered on, the communication module receives the firmware upgrade package, and a control module upgrades a public version software program according to the firmware upgrade package. ## Claims ### Claim 1 A refrigerator production line, comprising: a conveying device, configured to convey an assembled refrigerator, wherein the assembled refrigerator is assembled with a communication module and a control module, and the control module is stored with a public version software program; a scanning device, configured to scan and confirm an identification code of the assembled refrigerator and an address code of the communication module, wherein the scanning device is triggered when the assembled refrigerator is conveyed to a scanning region; and a local server, configured to store the identification code of the assembled refrigerator and the address code of the communication module, wherein the local server is further configured to acquire, in response to a firmware upgrade request, a firmware upgrade package, corresponding to the identification code, for the assembled refrigerator, wherein after the assembled refrigerator is powered on, the communication module receives the firmware upgrade package, and the control module upgrades the public version software program according to the firmware upgrade package. ### Claim 2 (depends on 1) The refrigerator production line according to claim 1, wherein the communication module is configured to report the address code to the local server, receive the identification code determined by the local server according to the address code, and provide the identification code to the control module. ### Claim 3 (depends on 1) The refrigerator production line according to claim 1, further comprising a firmware server, wherein the firmware server is configured to send the latest firmware upgrade package for the assembled refrigerator to the local server. ### Claim 4 (depends on 1) The refrigerator production line according to claim 1, further comprising a commodity detecting device, wherein the commodity detecting device is configured to detect a refrigeration performance and a power of the assembled refrigerator, wherein the commodity detecting device is triggered when the assembled refrigerator is conveyed to a commodity detecting region. ### Claim 5 (depends on 1) The refrigerator production line according to claim 1, wherein a conveying mode of the conveying device includes a plate type, a chain type, a drum type, or combinations thereof. ### Claim 6 (depends on 1) The refrigerator production line according to claim 1, further comprising a power supply device is-installed on the conveying device, wherein the power supply device moves synchronously along with the conveying device. ### Claim 7 A software upgrade method for a refrigerator in a production line, comprising: conveying an assembled refrigerator, wherein the assembled refrigerator is assembled with a communication module and a control module, wherein the control module is stored with a public version software program; scanning an identification code of the assembled refrigerator and an address code of the communication module after confirming the assembled refrigerator is conveyed to a scanning region; storing the identification code of the assembled refrigerator and the address code of the communication module in a corresponding manner; acquiring, in response to a firmware upgrade request, a firmware upgrade package corresponding to the identification code, for the assembled refrigerator; and upgrading the public version software program according to the firmware upgrade package after the assembled refrigerator is powered on. ### Claim 8 (depends on 7) The software upgrade method according to claim 7, further comprising: receiving the identification code of the assembled refrigerator corresponding to an address code of the communication module; providing the identification code to the control module; parsing the identification code to acquire a machine model of a complete machine of the assembled refrigerator; and sending the firmware upgrade request according to the machine model of the complete machine. ### Claim 9 (depends on 7) The software upgrade method according to claim 7, further comprising: confirming that the assembled refrigerator is conveyed to a commodity detecting region, and detecting a refrigeration performance and a power of the assembled refrigerator. ### Claim 10 (depends on 7) A non-transitory computer-readable storage medium having stored therein a computer program that, when executed by a processor, implements a software upgrade method for a refrigerator in a production line according to claim 7. ### Claim 11 (depends on 1) The refrigerator production line according to claim 1, wherein the control module is configured to parses the identification code to acquire a machine model of a complete machine of the assembled refrigerator, and send the firmware upgrade request according to the machine model of the complete machine.
