Embodiment Construction

[0035] Embodiment. The network topology of this example is as figure 1 As shown in , the AP node is arranged at the starting position of the transportation pipeline. The AP node has relatively strong control and processing capabilities, and it has three main functions: first, it is used to complete various commands to the network to control each ED node; second, it can realize the aggregation and upload of each ED node data Function; Third, it can realize the connection with other networks (such as Ethernet, GSM network, etc.). The ED nodes are arranged in sequence on the transportation pipeline, and the physical addresses of the nodes are arranged in ascending order, and the address interval of adjacent nodes can be greater than 1, so as to increase or decrease the pipeline monitoring nodes later, compatible with other network topologies, and enhance the maintainability of the network. The ED node can complete two network functions: first, it can be used as a data acquisitio...

Abstract

The invention discloses a wireless sensor network communication protocol method of an automatic cathodic protection data collection system and relates to the technical field of digital information transmission and pipe systems. The wireless sensor network communication protocol method adopts a three-layer protocol structure which comprises a physical radio frequency layer, a network layer and an application layer from bottom to top, wherein the physical radio frequency layer encapsulates data of the bottom layer into a frame structure, and a CSMA-CA carrier monitoring conflict avoidance algorithm is planted into the frame structure; the network layer achieves formation, retrieval and input and output control of data packets in the protocol and interface function transmission and reception by calling a software interface encapsulated by the physical radio frequency layer; the application layer establishes an application program interface function capable of achieving all functions of the application layer by calling a software interface provided by the network layer. By means of the wireless sensor network communication protocol method, communication can be guaranteed greatly, work efficiency of the automatic cathodic protection data collection system is greatly increased, management cost is reduced, and transport security of petroleum pipelines is guaranteed.

Description

technical field [0001] The invention relates to a wireless sensor network communication protocol method for a cathodic protection data automatic collection system, and relates to the technical fields of digital information transmission and pipeline systems. technical background [0002] Since the importance of monitoring the physical environment has never been more prominent than it is today, the Internet of Things has been seen as the next development in environmental monitoring, building monitoring, utilities, industrial control, home, marine and transportation system automation. From the perspective of realizing the function of the Internet of Things, the wireless sensor network (Wireless Sensor Networks, WSN) driven by micro-electromechanical system, system-on-chip, wireless communication and low-power embedded technology has a very good application prospect. Wireless sensor network is a new type of sensor network, which is composed of a large number of micro-sensor node...
