GPRS-based adjusting device for frequency of pumping unit

Abstract

The invention relates to a GPRS-based adjusting device for a frequency of a pumping unit. The GPRS-based adjusting device comprises a single-chip microcomputer control system, a standard signal acquisition module, a pulse signal acquisition module, a switching value input module, a switching value output module, and a data transmission terminal; the standard signal acquisition module and the pulse signal acquisition module are connected with the single-chip microcomputer control system; the switching value input module and the switching value output module are connected with the single-chip microcomputer control system; and the data transmission terminal is connected with the single-chip microcomputer control system. The standard signal acquisition module and the pulse signal acquisition module are installed on a pumping unit. According to the GPRS-based adjusting device provided by the invention, the motion frequency of the reversed well motor is low and the amplitude is small, so that the frequent overturning of a tipping bucket can be avoided and the service lives of the tipping bucket can be prolonged. The host can store data collected each day into a data base; and the terminal displays the data by using a 20*15 Chinese-character liquid crystal display device in a single-screen mode, so that visual and convenient effects can be realized.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a GPRS-based frequency adjustment device for pumping units. Background technique [0002] Pumping unit is a kind of machinery and equipment for oil extraction, commonly known as "kowtow machine", which makes oil out of the well by pressurizing. When the pumping unit is upstroke, the oil pipe elastically shrinks and moves upwards, driving the mechanical unblocking oil extractor to move upwards, hitting the sliding sleeve to generate vibration; at the same time, the forward check valve is closed, and the variable diameter piston assembly blocks the oil when the pumping unit goes down. During the stroke, the tubing elastically elongates and moves downward, driving the mechanical unblocking extractor to move downward, hitting the sliding sleeve to generate vibration; at the same time, the reverse check valve is partially closed, and the variable-diameter piston assembly still block...

AI Technical Summary

Problems solved by technology

[0003] The existing pumping unit adopts manual control of the oil pumping switch frequency, and it still operates at high speed when there is no oil and little oil, which reduces the service life of the pumping unit
