Oil derrick stress measurement and data acquisition system based on wireless sensor network

Abstract

The invention relates to an oil derrick stress measurement and data acquisition system based on a wireless sensor network, which comprises a vibrating string extensometer-detected marine oil derrick stress-strain subsystem, a marine oil derrick stress-strain field data transmission subsystem based on the wireless sensor network and a marine oil derrick capacity assessment subsystem based on a configuration technology and a Matlab computation program. In the system, an industrial computer is connected with a wireless sensor network gateway through an industrial concentrator, marine oil derrick stress-strain field data is converted into digital signals by wireless sensor network nodes, and then, the industrial computer reads data at each node in the wireless sensor network by using the Modbus TCP / IP communication protocol and an address distinguishing technology so as to realize the acquisition and transmission of the oil drilling derrick stress-strain field data. The system has the advantages of low cost and high stability, and is applicable to a derrick capacity detection and evaluation system in ocean severe environment.

Description

technical field [0001] The invention relates to an oil derrick stress measurement and data acquisition system, in particular to a derrick and rod member stress measurement and derrick bearing capacity measurement and data acquisition system for ocean drilling derrick static load test. Background technique [0002] With the development of offshore oil drilling and production projects in deep water and ultra-deep water, tower derricks with large bearing capacity, good stability and strong drilling depth have taken an absolute advantage in contemporary offshore oil drilling. In order to adapt to the harsh offshore weather environment and complex and changeable working conditions, the offshore oil drilling platform adopts a modular design that is convenient for rapid hoisting and connection at sea. transported to the oil production site. During the process of disassembly, transportation and erection, the derrick will inevitably appear or have different degrees of damage and def...
