Abstract

The invention discloses a remote upgrade method and a device based on main and auxiliary equipment. The method includes that main equipment receives first upgrade commands issued from a remote upgrade center and sends the first demand file upgrade commands; the main equipment stores a first upgrade file into a first temporary file; whether the main equipment verifies the first upgrade file successfully is judged, if the main equipment verifies the first upgrade file successfully, a first message successfully receiving the first upgrade file is sent to the remote upgrade center, if not, a second message unsuccessfully receiving the first upgrade file is sent to the remote upgrade center, and the step is finished after the second message is received; and the remote upgrade center receives the first message, whether upgrade is judged, if the upgrade is performed, a second affirmation upgrade message is sent to the main equipment, upgrade operations of the main and auxiliary equipment are performed respectively, if not, a negation upgrade message is sent to the main equipment, the first upgrade message is deleted, and the step is finished. According to the remote upgrade method and the device based on main and auxiliary equipment, the problem that equipment is inconvenient to maintain is solved, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of embedded devices, in particular to a remote upgrade method and device based on master-slave devices. Background technique [0002] In the application field of embedded devices, due to the continuous change of customer needs, it is necessary to update the program written in the embedded device. In addition, in order to solve the defects of the embedded software, the program is also required to have self-upgrading ability, through remote upgrade function, the latest and most stable program can be downloaded to the remote terminal device through the network, which is convenient for maintenance and saves a lot of cost. [0003] The current embedded devices based on the master-slave mode either do not support the remote upgrade function; or need to connect to the device through a serial port, network, FTP, etc. to perform the upgrade operation. This will inevitably require maintenance personnel to go to the site, conne...
