Equipment updating method, device and system

Abstract

The invention provides an equipment updating method and device and an equipment updating system. The equipment updating method is applied to a gateway, the gateway records information of target equipment needing to be updated, and when an updating notification message is received, the updating notification message is sent to equipment on an idle network segment in a plurality of network segments; when the response information fed back by the equipment on the idle network segments for the updating notification message is received, according to the response information and the information of the target equipment, non-updated target equipment is determined from each idle network segment with the non-updated target equipment as current to-be-updated equipment; response information fed back by the current to-be-updated equipment is sent to the control equipment; when the device updating information is received, the device updating information is sent to the current to-be-updated device, so that the current to-be-updated device is updated according to the device updating information. According to the invention, the devices on the plurality of idle network segments can be updated in parallel, the time consumed by the updating mode is short, and the utilization rate of the network bandwidth is high.

Description

technical field [0001] The present invention relates to the technical field of equipment updating, in particular to an equipment updating method, device and equipment updating system. Background technique [0002] In some scenarios, multiple devices in multiple network segments need to be updated. For example, multiple ECUs (Electronic Control Units, electronic control units) in different network segments are installed on a car. At some point, it is necessary to Update all or some ECUs. [0003] The current device update method is a serial update method, that is, the next device is updated only after one device is updated, and one device is updated each time. Although the serial update method can implement device update, the serial update method takes a long time and has a low utilization rate of the bus bandwidth. Contents of the invention [0004] In view of this, the present invention provides a device update method, device and system, which are used to solve the prob...
