Radio controller for oil gas pipeline control valve

Abstract

It is a kind of oil vapour channel actuated valve wireless circuit controller, which belongs to the wireless controller aduertiser. In allusion to the special running environment and the controlling condition, it is used to apply in the long-range monitored control system. The A / D conversion modular is combined with the PLC modular electric signal. The data station is connected with the PLC modular through the 485-interface module. The switch current source and the function modular are allocated in the data station. The A / D collects the compression force and the temperature signal and switchs with the A / D. the data station transfers the signal to the controlling center and control the valve seat. It is good for the centralized controlling of the oil-gas pipe networks. It can make the analysis of data collected and control reversibly. It has the long-range initiation, which has the functions of lemetering, remote-controlling and alarming automatically.

Description

technical field [0001] The invention belongs to a wireless control device, which is used for remote monitoring of oil and gas pipeline control valves. Background technique [0002] Large-diameter oil and gas pipeline valves are large-scale key basic equipment for long-distance transportation of oil and natural gas. They have multiple functions such as cut-off, opening, distribution, and pressure regulation. In order to ensure the normal operation of equipment, the safe transportation of resources and the safety of personnel, the whole process monitoring of oil and gas pipelines and valves is a long-term and important task. Large-diameter oil and gas pipeline valves are generally installed in the outskirts far from the city, and the natural environment is relatively harsh. Therefore, they are basically unattended and regularly sent to patrol. [0003] The oil and gas pipeline remote monitoring system is a set of data acquisition and valve control system for the valve status ...

AI Technical Summary

Problems solved by technology

[0004] The remote monitoring system can adopt many methods, such as building a private network, pulling a dedicated line, using the general packet radio service GPRS (General Packer Radio Service) or code division multiple access CDMA (Code Division Multiple Access), but these methods have large initial investment, Problems such as high operating costs or poor maintainability
