Problems solved by technology

[0009] However, because this method uses unicast to transmit data, it needs to establish a connection with each device and send the upgrade data separately, and the utilization rate of network resources is low.
And because this method is to upgrade each device one by one, when a large number of devices need to be upgraded, the upgrade cycle will be long
[0010] Moreover, this method uses the method of directly overwriting the original data with the upgraded data to upgrade the device. When a network failure or device abnormality occurs, the upgrade may fail and cannot be recovered. Engineers need to go to the site to re-upgrade or restore the system through the serial port.

Embodiment Construction

[0033] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail:

[0034] An upgrade data sending device of the present invention such as figure 2 As shown, it includes a multicast group management unit 21, an upgrade management unit 22 and a version information storage unit 23; wherein the upgrade management unit 22 is connected to the multicast group management unit 21 and the version information storage unit 23 respectively.

[0035] The multicast group management unit 21 is configured to generate a multicast group and send upgrade data to the multicast group. The upgrade management unit 22 is used for selecting the equipment to be upgraded, grouping the equipment to be upgraded, and distributing a multicast group for each group of equipment to be upgraded; and sending the multicast address of the corresponding multicast group to the equipment to be upgraded, and sending the equipment to ...

Abstract

This invention discloses one method to update imbed device remote batch, which comprises the following steps: sending the update data into device to be updated through set broadcast type; the device to be updated keeps pre-data for updating by use of update data. This invention also discloses one imbed update data send device one imbed device to update multiple devices with short circle.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for remote batch upgrading of embedded devices. Background technique [0002] At present, the upgrade of remote embedded devices is mainly for engineers to go to the device site, send control commands through the computer serial port, and transmit the upgrade data through the Ethernet port, and upgrade the devices one by one. With the increasingly widespread application of embedded devices, the number of embedded devices continues to increase, and the places where they are distributed are becoming more and more complex. Therefore, it is becoming more and more difficult to upgrade the devices, and this upgrade method has been difficult to meet the demand. [0003] In order to solve the above problems, the remote login method is now used to upgrade the embedded device, which realizes the remote upgrade of the embedded device without the need for en...
