Embodiment Construction

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] The present invention provides a method for realizing roaming among different networks by a WIA-PA network node. The invention groups the frequency points of the ISM2.4G frequency band, different groups of networks broadcast on the agreed and different time slots, and the node recognizes the existence of the new network by receiving the broadcast. And through the current network and other identified network broadcast signal strength changes, decide whether to join other networks, network switching. The roaming of WIA-PA dynamic nodes between different networks is realized.

[0034] A method for implementing roaming by a WIA-PA network node includes further division of ISM2.4G frequency band usage rules, and operations to be performed by a node implementing roaming.

[0035] There are 16 available channels (numbered 11-26) in the ISM2.4G...

Abstract

The invention relates to a WIA-PA node network roaming method, which comprises the following steps of: dividing a WIA-PA network into a plurality of modes, and dividing each mode by using a channel; when the node accesses the network, monitoring the broadcast frame on the broadcast channel in each mode in sequence; when the broadcast frame is monitored in a certain mode, the network in the mode is added; after the nodes access the network, communication is carried out in the channels distributed in the network, and the change of broadcast signal strength in each superframe of the current network is recorded; and when the broadcast signal intensity average value of a certain other network is greater than the broadcast signal intensity average value of the current network, taking the other network as a new network. According to the method, frequency points of an ISM 2.4 G frequency band are grouped, different groups of networks send broadcasts in agreed different time slots, and nodes identify the existence of a new network by receiving the broadcasts. And whether other networks are added or not is determined according to the change of the broadcast signal intensity of the current network and the identified other networks, and network switching is carried out. The roaming of the WIA-PA dynamic node among different networks is realized.

Description

technical field [0001] The invention belongs to the application field of industrial wireless network technology WIA-PA, in particular to a method for realizing roaming between different networks by a WIA-PA network node. Background technique [0002] WIA-PA industrial wireless network technology is widely used in industrial production scenarios such as oil fields because of its low delay, flexible deployment, and strong anti-multipath interference capabilities. . The current WIA-PA network node needs to configure the channel information of the network in advance before joining the network. If the node needs to move dynamically and enter the coverage area of ​​other networks, network information needs to be configured outside the network, and the node can only access the network after performing the network access process. Switching the network in this way is a cumbersome operation, and the node will be disconnected from the network for a period of time, resulting in data i...
