As shown in fig. 2, fig. 2 is a flowchart illustrating a firmware upgrading method according to a first embodiment of the present invention.
While a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different than presented herein.
In each embodiment of the firmware upgrading method, the scheme of the embodiment of the invention mainly relates to a household appliance and a server.
Referring to fig. 2, in a first embodiment of a firmware upgrade method according to the present invention, the firmware upgrade method is applied to an appliance, and the firmware upgrade method includes:
step S110, sending the distribution network information of the household appliances to a server;
in this embodiment, the home appliance establishes a network connection with the server through the built-in WIFI module. Therefore, the household appliance downloads the firmware upgrading package from the server, and the firmware of the household appliance is upgraded, so that the firmware of the household appliance is upgraded.
Specifically, in one embodiment, the home appliance detects that: after the query instruction generated by the server paired with the household appliance, the household appliance queries the distribution network information stored on Flash (Flash, solid-state memory and animation editor), and sends the distribution network information stored on the Flash of the household appliance to the server so as to provide a firmware upgrade package generated by the server based on the distribution network information.
In one embodiment, the household appliance sends the distribution network information of the household appliance to a server paired with the household appliance at regular time. After the server detects the new firmware to be upgraded, the server acquires the equipment identification number of the household appliance to be upgraded, and the server acquires the distribution network information sent by the household appliance corresponding to the equipment identification number.
The query instruction refers to an instruction which is generated by the server and used for querying the distribution network information of the household appliance before the firmware upgrade package is sent to the household appliance. The distribution network information refers to information necessary for establishing network connection between the household appliance and the server.
Further, step S110 includes:
detecting whether an inquiry instruction generated by a server paired with the household appliance is received;
and if the inquiry command is detected, sending the distribution network information of the household appliance to the server.
After detecting the new firmware to be upgraded, the server acquires the equipment code of the household appliance to be upgraded; the device code of the household appliance can be input into the server by a person or acquired by the server from a third party. And the server searches the equipment identification number corresponding to the equipment code from the server according to the equipment code. And the server sends a query instruction for querying the distribution network information of the household appliance to the corresponding household appliance according to the equipment identification number. Household appliance detection: whether an inquiry command generated by a server paired with the household appliance is received.
After the household appliance detects the query instruction generated by the server, the household appliance queries the distribution network information stored on the Flash, and sends the distribution network information stored on the household appliance Flash to the server so as to enable the server to generate a firmware upgrading package based on the distribution network information.
And if the household appliance does not detect the query instruction generated by the server, continuing to wait for the query instruction sent by the server.
Step S120, acquiring a firmware upgrading packet generated by the server based on the distribution network information;
after receiving the distribution network information sent by the household appliance, the server packs the distribution network information of the household appliance, the equipment identification number of the household appliance and the new firmware to be upgraded to form a firmware upgrade package; and returning the firmware upgrade package to the household appliance according to the equipment identification number of the household appliance. The household appliance acquisition server generates a firmware upgrade package based on the distribution network information.
The firmware upgrading package is formed by the server packaging the distribution network information of the household appliances, the equipment identification numbers of the household appliances and the new firmware to be upgraded based on the distribution network information sent by the household appliances.
Step S130, the firmware upgrade of the household appliance is completed according to the firmware upgrade package, and the network connection between the household appliance and the server is established according to the distribution network information in the firmware upgrade package.
And after the firmware upgrading packet is returned to the household appliance, the server sends an upgrading instruction to the household appliance. After receiving an upgrading instruction sent by a server, the household appliance obtains new firmware from a firmware upgrading package fed back by the server; and the firmware upgrade of the household appliance is completed according to the new firmware. After the firmware of the household appliance is upgraded, the household appliance sets a starting sector zone bit so as to restart and run a new firmware. After the new firmware is started, the household appliances read the distribution network information and the equipment identification codes of the household appliances from the firmware upgrading package fed back by the server, and establish network connection with the server according to the read distribution network information and the equipment identification codes. Here, the home appliance establishes a network connection with the server, and the home appliance refers to a terminal after firmware upgrade is completed.
The new firmware refers to firmware for upgrading firmware of the household appliance.
In this embodiment, the server sends the query instruction to the home appliance, and the home appliance sends the distribution network information of the home appliance to the server after receiving the query instruction from the server; the server packages a new firmware to be upgraded and the distribution network information into a firmware upgrading package according to the distribution network information sent by the household appliance and sends the firmware upgrading package to the household appliance; the household appliance upgrades the firmware according to the firmware upgrade package, and after the firmware is upgraded, the distribution network information of the household appliance is acquired from the firmware upgrade package and is connected with the server through a network. After the firmware of the household appliance is upgraded, the household appliance can directly acquire the distribution network information of the household appliance and establish network connection with the server, so that the manual distribution network process is not needed. The problem that the network distribution of the household appliances needs to be manually and again manually carried out due to the fact that the household appliances cannot determine the network distribution information of the household appliances after the firmware is upgraded because the framework of the old firmware adopted in the household appliances is different from the framework of the new firmware and the household appliances cannot automatically establish network connection with the server is solved.
Further, referring to fig. 3, fig. 3 is a schematic flowchart illustrating a detailed process of step S130 in a second embodiment of the firmware upgrading method according to the present invention, and the firmware upgrading packet includes the distribution network information, the device identification number of the household appliance, and a new firmware to be upgraded, based on the first embodiment of the firmware upgrading method according to the present invention;
the step S130 includes:
step S131, acquiring the new firmware from the firmware upgrade package, and completing the firmware upgrade of the household appliance according to the new firmware;
and the household appliance acquires new firmware for upgrading the firmware of the household appliance from the firmware upgrading package fed back by the server. The architecture of the old firmware adopted in the household appliance is different from that of the new firmware, so that the household appliance writes the new firmware into a new sector of the household appliance to finish the firmware upgrade of the household appliance.
Step S132, restarting the firmware of the household appliance, and acquiring the equipment identification number and the distribution network information of the household appliance from the firmware upgrade package;
because the old device identification number stored in the household appliance is different from the new device identification number re-allocated to the household appliance by the server, if the household appliance adopts the old device identification number to establish connection with the server, the household appliance and the server still cannot perform normal network connection. Therefore, when the server returns the firmware upgrade package to the household appliance, the server reallocates the new equipment identification number of the household appliance, the distribution network information of the household appliance and the new firmware to be packaged together to form the firmware upgrade package, and then the firmware upgrade package is returned to the household appliance, so that the household appliance can acquire the new equipment identification number and establish connection with the server.
And after the household appliance writes the new firmware into the new sector of the household appliance, setting a starting sector zone bit to start the new firmware of the household appliance. And after the new firmware of the household appliance is restarted, the household appliance acquires the equipment identification number newly distributed to the household appliance by the server and the distribution network information of the household appliance from the firmware upgrading packet fed back by the server.
And step S133, connecting the household appliance to the server according to the equipment identification number and the distribution network information.
The household appliance sends a connection request to the server based on the equipment identification number of the household appliance and the distribution network information of the household appliance. And after receiving the connection request of the household appliances, the server establishes network connection with the household appliances according to the equipment identification number of the household appliances and the distribution network information of the household appliances. Therefore, the whole firmware upgrading process of the household appliance is completed, and the household appliance is automatically connected with the server after the firmware upgrading is completed.
In this embodiment, the household appliance obtains the distribution network information of the household appliance from the firmware upgrade package fed back by the server, and establishes network connection with the server according to the distribution network information of the household appliance. Therefore, the situation that the household appliances cannot acquire the distribution network information of the household appliances and cannot be connected with the server is avoided. The household appliance obtains the equipment identification number re-allocated to the household appliance by the server from the firmware upgrading packet fed back by the server, and establishes network connection with the server according to the equipment identification number re-allocated to the household appliance by the server, so that the household appliance is prevented from adopting an old equipment identification number stored by the household appliance.
Further, based on the second embodiment, a third embodiment of the firmware upgrading method according to the present invention is provided, and after step S110, the method further includes:
and acquiring a check code generated by the server based on the distribution network information.
In this embodiment, in order to avoid that the home appliance cannot completely receive the firmware upgrade package sent by the server, after receiving the distribution network information sent by the home appliance, the server packages the distribution network information of the home appliance, the device identification number of the home appliance, and the new firmware to be upgraded to form the firmware upgrade package, and generates the check code of the firmware upgrade package, for example, generates the CRC code when the firmware upgrade package is packaged. And then, the server returns the firmware upgrade package and the check code to the household appliance according to the equipment identification number of the household appliance. The household appliance acquisition server generates a firmware upgrade package and a check code based on the distribution network information.
The check code is a verification code, such as a CRC code, for verifying whether the firmware upgrade package received by the home appliance is accurate.
Further, step S131 includes:
step A1, after detecting the upgrade order sent by the server, according to the check code, detecting whether the firmware upgrade package is complete;
and after the firmware upgrading packet and the check code are returned to the household appliance, the server sends an upgrading instruction to the household appliance. And after detecting the upgrading instruction sent by the server, the household appliance checks whether the received check code is correct or not. If the home appliance checks that the check code is incorrect, the home appliance is proved to receive the incomplete firmware upgrade package; if the home appliance checks that the check code is correct, the home appliance is proved to receive the complete firmware upgrading package, and the firmware can be further upgraded.
Step A2, if the firmware upgrade package is detected to be complete, acquiring the new firmware from the firmware upgrade package;
and if the household appliance detects that the firmware upgrade package received by the household appliance is complete, the household appliance obtains new firmware for upgrading the firmware of the household appliance from the firmware upgrade package fed back by the server.
And if the household appliance detects that the firmware upgrade package received by the household appliance is incomplete, the household appliance deletes the firmware upgrade package downloaded from the server and sends a download error instruction to the server. And after receiving the error downloading instruction sent by the household appliance, the server pushes new firmware next time based on the error downloading instruction sent by the household appliance.
And A3, finishing the firmware upgrade of the household appliance according to the new firmware.
Specifically, since the architecture of the old firmware adopted in the home appliance is different from the architecture of the new firmware, the home appliance writes the new firmware into the new sector of the home appliance to complete the firmware upgrade of the home appliance. Wherein the new firmware writes a new sector different from the sector where the old firmware is located.
In this embodiment, the home appliance generates the check code according to the server, checks whether the firmware upgrade package acquired from the server is complete, and after confirming that the firmware upgrade package acquired from the server is complete, the home appliance acquires new firmware from the firmware upgrade package to complete firmware upgrade, thereby ensuring that the home appliance can complete the firmware upgrade process; the firmware upgrading method and the firmware upgrading device avoid the failure of firmware upgrading of the household appliances caused by the fact that the household appliances cannot finish firmware upgrading according to the firmware upgrading package due to the fact that the firmware upgrading package obtained by the household appliances from the server is incomplete.
Further, based on the third embodiment, a fourth embodiment of the firmware upgrading method of the present invention is provided, where the step of detecting whether the firmware upgrade package is complete further includes:
step B1, if the firmware upgrade package is detected to be incomplete, deleting the acquired firmware upgrade package, and sending a download error instruction to the server;
if the household appliance detects that the household appliance receives the incomplete firmware upgrading packet, the household appliance deletes the firmware upgrading packet downloaded from the server and sends a downloading error instruction to the server, so that the server determines the reason for failure of firmware upgrading of the household appliance according to the downloading error instruction, and the server pushes the firmware to the household appliance again according to the reason for failure of firmware upgrading.
And if the household appliance detects that the firmware upgrade package received by the household appliance is complete, the household appliance obtains new firmware for upgrading the firmware of the household appliance from the firmware upgrade package fed back by the server.
And step B2, the query instruction generated by the server based on the download error instruction is obtained again.
And after receiving the downloading error instruction sent by the household appliance, the server judges whether to push the new firmware or not based on the downloading error instruction sent by the household appliance. And when the new firmware pushing is determined, the server sends the query instruction to the household appliances again so as to query the distribution network information of the household appliances. And realizing the steps of upgrading the firmware of the household appliance. When the home appliance detects the query command again, the above step S10 is returned to and continuously performed to perform the steps of firmware upgrade of the home appliance.
For example, the household appliance detects the firmware upgrade package through the CRC code, deletes the downloaded firmware upgrade package when detecting that the CRC code is incorrect, and sends a download error instruction to the server according to the detection result of the CRC code. The home appliance waits for the polling command next sent by the server, and when the home appliance again detects the polling command, returns to and continues to execute the above step S10.
In this embodiment, the home appliance generates a check code according to the server, checks whether the firmware upgrade package acquired from the server is complete, and when detecting that the firmware upgrade package acquired from the server is incomplete, the home appliance deletes the acquired firmware upgrade package, thereby avoiding that a useless file occupies a memory of the home appliance; meanwhile, the household appliance sends the error downloading instruction to the server, and the server further pushes new firmware to the household appliance according to the error downloading instruction sent by the household appliance so as to upgrade the firmware of the household appliance. Therefore, the server can accurately push the new firmware according to the information fed back by the household appliance, and the household appliance can accurately finish the firmware upgrading process.
Further, referring to fig. 4, fig. 4 is a flowchart illustrating a fifth embodiment of a firmware upgrading method according to the present invention, where in the fifth embodiment of the firmware upgrading method according to the present invention, the firmware upgrading method is applied to a server, and the firmware upgrading method includes:
step S210, after detecting the new firmware to be upgraded, acquiring the equipment identification number of the household appliance;
in this embodiment, the home appliance establishes a network connection with the server through the built-in WIFI module. Therefore, the household appliance downloads the firmware upgrading package from the server, and the firmware of the household appliance is upgraded, so that the firmware of the household appliance is upgraded.
The device identification number refers to a device ID number assigned to the household appliance by the server, and the household appliance establishes network connection with the server based on the device identification number.
After detecting the new firmware to be upgraded, the server acquires the equipment code of the household appliance to be upgraded; the device code of the household appliance can be input into the server by a person or acquired by the server from a third party.
And the server searches the equipment identification number corresponding to the equipment code from the server according to the equipment code.
