Abstract

The invention provides a software remote upgrading method for network terminal devices, for effectively solving the problem of remotely upgrading equipment firmware, greatly reducing equipment maintenance work and accordingly decreasing the maintenance cost. An LwIP protocol stack is transplanted on the devices so as to enable the devices to support TCP / IP protocol communication; the devices always maintain in Socket connection with a far-end server in an operation process; the server manages the connected devices and stores data transmitted by the far-end devices to the server; the server stores an equipment upgrading firmware version for issuing firmware to the devices; and after the devices receive an upgrading instruction, an upgrading step is carried out.

Description

technical field [0001] The invention relates to a method for remotely upgrading software of network terminal equipment, which is mainly applicable to software updating of embedded network equipment, and is particularly suitable for software updating of embedded network equipment in the field of the Internet of Things. Background technique [0002] With the rapid development of information technology, users' demands for products are becoming more and more diverse. How to maintain and upgrade products with a long market is also a problem that manufacturers need to face. At present, most embedded systems do not support software upgrades. After a problem occurs, it can only be solved on site or the product is recalled. The maintenance cost is high, and if the maintenance If it is not timely, it may face the risk of being replaced by customers, and then lose customer resources. [0003] The Chinese patent with the application number 201410406157.4 discloses an online upgrade met...
