Method for remotely upgrading mobile machinery controller

Abstract

The invention relates to a method for remotely upgrading a mobile machinery controller, which comprises the following steps: communication connection with a mobile machinery terminal is established through a remote server, and an upgrading command is issused; an auxiliary processor in the mobile mechanical terminal downloads the upgrade data packet to the local according to the path and the encryption mode contained in the upgrade command; an auxiliary processor in the mobile mechanical terminal verifies the upgrade data packet, and after the upgrade data packet passes the verification, original data of a main processor in the mobile mechanical terminal is backed up; an auxiliary processor in the mobile mechanical terminal erases data in a memory in a main processor in the mobile mechanical terminal, and then writes the upgrade data packet into the memory in the main processor in the mobile mechanical terminal; an auxiliary processor in the mobile mechanical terminal controls a main processor in the mobile mechanical terminal to carry out software upgrading; in the upgrading process, the remote server can carry out monitoring, and the original data of the main processor in the mobile mechanical terminal can be recovered after upgrading is unsuccessful. According to the method, reliable remote upgrading of the mobile mechanical controller can be realized.

Description

technical field [0001] The invention belongs to the technical field of controller upgrading, and in particular relates to a method for remotely upgrading a mobile mechanical controller. Background technique [0002] Mobile machinery is used in a harsh environment and is mostly used in remote areas. During the use of mobile machinery, there will be problems due to software defects or lack of functions, which will cause greater losses. When this happens, it is generally necessary to modify the software program, which requires service personnel to arrive at the scene in time for service. However, because mobile machinery is used in various occasions, and most of them are located in remote areas, it will cause many problems such as long service cycle, wide distribution of required service points, and large consumption of human resources. In order to solve the above problems, it is urgent to solve the dilemma of software upgrading. Contents of the invention [0003] Aiming a...
