Method for upgrading door lock firmware, upgrading system, intelligent gateway and storage medium

Abstract

The invention relates to a door lock firmware upgrade method, an upgrade system, an intelligent gateway and a storage medium. The upgrade method receives heartbeat information sent by the door lock, and judges the door lock according to the firmware version information in the heartbeat information and the version information of the preset firmware upgrade Whether firmware upgrade is required, when it is judged that the door lock needs firmware upgrade, query the preset upgrade database to obtain the upgrade status information of the door lock, when the upgrade status information is non-upgrade status, write the firmware version information into the preset upgrade database and set the upgrade status information to the download upgrade status. When the upgrade status information is the download upgrade status, query the preset upgrade database to obtain the delivery progress location information of the preset upgrade firmware, and upgrade from the preset location according to the delivery progress location information. The firmware obtains the delivery task data block corresponding to the delivery progress position and delivers it, and updates the delivery progress position information according to the feedback information of the door lock, which improves the upgrade efficiency.

Description

technical field [0001] The invention relates to the field of access control, in particular to a method for upgrading door lock firmware, an upgrading system, an intelligent gateway and a storage medium. Background technique [0002] The door lock upgrade method generally adopts the disassembly method, such as the special interface upgrade of the main control chip and the ISP (In-System Programmability, in-system programmable) upgrade. Among them, the special interface of the main control chip needs a special Flash burning tool, and the program to be upgraded Import it into the burning tool, and then burn it into the main control chip through the special upgrade interface of the door lock. For the ISP upgrade, it needs to be written by the software of the host computer and through the serial port of the door lock under the guidance of the preset upgrade program. To the main control chip, in short, the traditional upgrade method requires an upgrade tool to be physically connec...

[0002] The door lock upgrade method generally adopts the disassembly method, such as the special interface upgrade of the main control chip and the ISP (In-System Programmability, in-system programmable) upgrade. Among them, the special interface of the main control chip needs a special Flash burning tool, and the program to be upgraded Import it into the burning tool, and then burn it into the main control chip through the special upgrade interface of the door lock. For the ISP upgrade, it needs to be written by the software of the host computer and through the serial port of the door lock under the guidance of the preset upgrade program. To the main control chip, in short, the traditional upgrade method requires the physical connection between the upgrade tool and the main control chip, which is cumbersome and inconvenient to operate.

[0003] Therefore, the current door locks are upgraded by OTA (Over the Air Technology). However, in the Sub-1G Internet of Things LAN, the bandwidth resources of Sub-1G are tight. In the same LAN, the same gateway may Corresponding to multiple door locks, when one of the door locks is upgraded and the upgrade data packet is transmitted between the gateway, it will occupy the above-mentioned Sub-1G bandwidth resources for a long time, which often affects the connection between other door locks and the above-mentioned gateway. normal communication
