Software upgrading method and system for upper computer

Abstract

The invention discloses a software upgrading method and system for an upper computer. The software upgrading method comprises following steps: S1, a wireless module logs in a server at set intervals; S2, the wireless module detects whether the software upgrade package is upgraded, and if yes, the step S3 is executed; S3, the wireless module downloads the upgraded software upgrade package from the server; S4, the wireless module sends an upgrading instruction to the upper computer; S5, an upgrading marker bit is set by the upper computer; S6, the upper computer judges whether the upgrading marker bit is detected in a restart process, and if yes, a step S7 is executed; S7, the upper computer reads data of the software upgrade package segmentally from the wireless module and writes the read data into a program storage area until all data is written into the program storage area. Compared with the prior art, the method has the advantages that the data of the software upgrade package is read segmentally from the wireless module and written into the program storage area, so that the software upgrading of the upper computer can be realized under the condition of limited storage space, and the cost is saved.

Description

technical field [0001] The invention relates to the field of software upgrades, in particular to a software upgrade method and system for a host computer. Background technique [0002] At present, in the wireless devices designed and operated in the field of M2M (Machine to Machine, communication between machines) and the Internet of Things, the architecture combining the upper computer and the wireless module is basically adopted, and the wireless module provides the wireless link. , the upper computer realizes the application logic. Because the operating environment of wireless devices is usually more diverse and complex, when problems are found during use or there are changes in requirements, it is more difficult to upgrade the device software at this time, which requires high capital and labor costs. [0003] As for the wireless module, remote upgrade can be carried out through FOTA (Firmware Over-The-Air, software upgrade over the air for mobile terminals). But in som...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the defect that the upper computer with limited storage space in the prior art needs to be sent back to the manufacturer or sent to the site to upgrade the software, or the storage space needs to be expanded, resulting in an increase in cost. Software upgrade method and system for upper computer with low reliability and high reliability
