Energy saving system of networked measuring and controlling pumping units

Abstract

A network detecting and controlling system of pumping unit is featured as dynamically collecting pressure and displacement on-site data of pumping unit by transducer then sending said data to on-site controller, using driving controller to make motor of pumping unit regulate speed, measuring parameter of power supply subsystem by relay protective unit to judge out overpressure and overcurrent protection of motor and controller on pumping unit, carrying out remote communication with the second radio communication unit (RCU) in remote monitor and information management system through the first RCU, connecting the second RCU to control center being used to contact with mobilephone through GSM.

Description

technical field [0001] The invention belongs to the technical field of automatic measurement and control and intelligent instrumentation, relates to an integrated automatic measurement and control management system integrating measurement, control and management, and further relates to a network measurement and control energy-saving system for pumping units. Background technique [0002] At present, in the field of automatic control technology of pumping units, the relay protection of pumping units, automatic adjustment of energy-saving strokes, remote monitoring of oil machines, dynamic data collection and management of oil machines, etc., have not yet achieved effective integration of measurement, control and management. change. Basically, it is the traditional operation method of only installing relay protection devices on the pumping unit. Since the pumping unit is located in the field, it is scattered and unmanned. When the pumping unit fails, it...

Problems solved by technology

Basically, it is the traditional operation method of only installing relay protection devices on the pumping unit. Since the pumping unit is located in the field, it is scattered and unmanned. When the pumping unit fails, it cannot be eliminated in time, which will affect the normal operation of the pumping unit. ; especially because the dynamic data of the pumping unit and its oil well cannot be obtained in time, and there is no dynamic intelligent measurement and control equipment, the working efficiency of the pumping unit is low, and the automatic regulation and energy saving of the pumping unit cannot be realized, resulting in a great waste of resources; The pumping unit lacks dynamic data collection, data storage, data analysis, data query, etc., so that it brings more difficulties to management, decision-making and maintenance of the pumping unit
