Cathodic protection data automatic collection system based on wireless sensor network

Abstract

The invention discloses a cathode protection data automatic acquisition system based on a wireless sensor network. The system is based on a radio frequency transceiver CC1110, adopts a time division multiplexing working mode, and mainly comprises a solar power supply module, a power circuit, the radio frequency transceiver CC1110, a down link and an up link, wherein the solar power supply module is connected with a radio frequency single chip processor; the input end of the radio frequency single chip processor is connected with a data acquisition module; the output end of the radio frequency single chip processor is connected with an impedance conversion circuit; the output end and the input end of the impedance conversion circuit are respectively connected with the input end and the output end of the first radio frequency switch; the output end of a first radio frequency switch is connected with the down link; the output end of the down link is connected with a second radio frequency switch; the output end of the second radio frequency switch is connected with a transceiver antenna; the other output end is connected with the up link; the up link is connected with the first radio frequency switch; a switch control output end of the radio frequency single chip processor is connected with the first radio frequency switch and the second radio frequency switch. The automatic acquisition system can implement automatic data acquisition, transmission and timed monitoring.

Description

technical field [0001] The invention relates to an automatic cathodic protection data collection system based on a wireless sensor network, and relates to the technical fields of general anticorrosion of metal materials and pipeline systems. [0002] technical background [0003] Pipeline transportation is one of the five major transportation modes of the national economy, and energy transmission pipelines often have to pass through long and difficult areas to monitor. In order to ensure the safety and reliability of pipeline transportation, establishing a powerful and intelligent monitoring and network management system is the direction of recent pipeline development. [0004] Realistic demand is the driving force for the development of new technologies. In the past two years, the rapid development of Wireless Sensor Network (WSN: Wireless Sensor Network) has greatly expanded the coverage of the current monitoring network. It provides a new idea to solve the existing data c...
