Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the use of channel hopping technology for the prior art cannot solve the interference problem between IEEE 802.15.4 networks. In IEEE 802.15.4 Under the interference of the wireless network, the WIA-PA network calculates the time period of the conflict domain between the two networks according to the data period sent by the IEEE 802.15.4 network. The WIA-PA network gateway system manager adjusts the period of data sent by the network device , to avoid working during the IEEE 802.15.4 network collision time period

Embodiment Construction

[0021] In order to make the purpose of the present invention, technical solutions and advantages clearer, the present invention will be described in further detail below in conjunction with accompanying drawing:

[0022] The MAC layer and the physical layer of the WIA-PA protocol are based on the IEEE 802.15.4 standard. Therefore, the data packets of the IEEE 802.15.4 network are identified through the WIA-PA network. Such as figure 1 Shown is a flowchart of a method for coexistence of WIA-PA and IEEE 802.15.4 networks based on beacon frame scheduling. Specifically:

[0023] If WIA-PA network and IEEE 802.15.4 network interfere with each other, perform wireless communication. The gateway device of the WIA-PA network periodically listens to the beacon frame sent by the IEEE 802.15.4 network, and parses the MAC frame header of the IEEE 802.15.4 network beacon frame to determine whether the IEEE 802.15.4 network is working in security mode; if The IEEE 802.15.4 network MAC lay...

Abstract

The invention discloses a coexistence method for a WIA-PA network and an IEEE 802.15.4 network and relates to an industrial wireless sensor network. Gateway equipment in the WIA-PA network learns and acquires the data packet transmission cycle of the IEEE 802.15.4 network by snooping a beacon frame transmitted by an IEEE 802.15.4 interference network; and a WIA-PA network system manager adjusting the scheduling time of the network equipment by redistributing the network resource so as to avoid interference. According to the coexistence method, the spectrum resources of the network can be utilized completely and communication reliability and stability of the WIA-PA network can be improved effectively.

Description

technical field [0001] The invention relates to the technical field of industrial wireless sensor networks, in particular to a coexistence method of a WIA-PA network and an IEEE 802.15.4 network. Background technique [0002] Industrial wireless sensor network has become a hot direction in the field of industrial control, and it is also a new growth point for industrial automation products in the future. At present, the establishment of industrial wireless standards has become the focus of industrial wireless technology competition. In the industrial world, if a wired sensor network is used, the cost is high and it is difficult to implement. The introduction of the industrial wireless sensor network solves the problems of difficult industrial field wiring and high installation and maintenance costs. With its low power consumption and low cost, industrial wireless sensor network has become another development trend in the field of industrial automation. It has become an urg...
