Problems solved by technology

Although this patent can remotely update files, it does not provide measures for stable transmission of update data, so the update data transmission is unstable and the update failure rate is high
Moreover, this patent is not fully applicable to the remote update of firmware, especially the update of network devices involving multiple device nodes, the workload is heavy and the update time is long

Embodiment 1

[0054] When updates are required, the gateway broadcasts update notifications and firmware update information. The firmware update information includes information such as firmware type, firmware version number, and firmware length. Such as figure 2 As shown, at least one coordinator parses the firmware version number, firmware type and firmware length in the firmware update information after receiving the update notification broadcast by the gateway. The coordinator will determine whether its own firmware version number is lower than the firmware version number in the update notification. If the firmware version number of the coordinator itself is higher than or equal to the firmware version number in the update notification, the current firmware version will be maintained. If the firmware version number of the coordinator itself is lower than the firmware version number in the update notification, the coordinator generates an update request and sends the update request to...

Embodiment 2

[0059] This embodiment is a further improvement on the basis of Embodiment 1.

[0060] The gateway broadcasts firmware update information to at least one coordinator. The coordinator parses information such as firmware version number, firmware type, and firmware length in the firmware update information. The coordinator calculates the total number of frames for updating data based on the firmware length. The coordinator sends an update request to the gateway whose firmware version number is higher than its own version number. The gateway responds to the update request by sending update data frame by frame. The coordinator receives the update data frame by frame and saves it.

[0061] According to a preferred implementation manner, the firmware update information broadcast by the gateway carries a set check value. The set check value includes CRC value. The coordinator parses the set check value in the firmware update information. After the coordinator receives all the up...

Embodiment 3

[0065] The present invention is a further improvement on the basis of Embodiment 2.

[0066] A gateway connects at least one network device. Network devices include coordinators, smart lighting devices, smart home appliances, and smart electronic devices. This embodiment will be described with intelligent lighting equipment.

[0067] The gateway is connected to at least one intelligent lighting device through a wireless network. The smart lighting device receives the broadcast update notification from the gateway. The firmware update information is included in the broadcast update notification. The smart lighting device parses the firmware update information, and reads the firmware update information in the form of a hex file. The smart lighting device reads the firmware update information line by line. Read from index=0, read 4 lines each time, a total of 64 bytes, that is, an index.

[0068] The smart lighting device compares the update version number with its own firm...

Abstract

The invention discloses a remote update method and system. The method comprises the following steps: receiving firmware update information broadcast by a gateway through at least one coordinator; sending an update request for requesting update data to the gateway; receiving the update data taking frames as units transmitted by the gateway in response to the update request; updating firmware based on the received update data; and simultaneously transmitting the update data taking the frames as the units to two non-updated coordinators by updated coordinators, and updating all the coordinators at an update speed being an exponential multiple of 2. According to the method and the system, remote update processes is executed in background, so that normal use of current network equipment is not influenced, and the network equipment can process other data normally in the remote update processes. The remote update processes of the network equipment are independent, so that mutual influences are avoided, and the update efficiency is increased.

Description

technical field [0001] The invention relates to the field of network technology. In particular, it relates to a remote update method and system. Background technique [0002] ZigBee technology is a two-way wireless communication technology with short distance, low complexity, low power consumption, low speed and low cost. ZigBee is a highly reliable wireless data transmission network, similar to CDMA and GSM networks. ZigBee data transmission module is similar to mobile network base station. The communication distance ranges from the standard 75m to hundreds of meters and several kilometers, and supports unlimited expansion. ZigBee is a wireless data transmission network platform composed of up to 65535 wireless data transmission modules. Within the entire network range, each ZigBee network data transmission module can communicate with each other, and the distance between each network node can be from Standard 75m unlimited extension. [0003] ZigBee is a low-power LAN ...
