A kind of intelligent control method of pumping unit

Abstract

The invention discloses a pumping unit intelligent control method. The method includes the steps that oil well electrical data and mechanical parameters are encapsulated after being subjected to signal processing, wherein the oil well electric data and the mechanical parameters are detected by a pumping unit terminal; field parameters are transmitted to a remote control terminal through a 4G communication network or a 3G communication network at a fixed time; the remote control terminal analyzes the field parameters according to acquired information; when judging that the data are abnormal, the remote control terminal sends signal acquisition video data to the side of a pumping unit to confirm field conditions; when abnormity really occurs in a field, the remote control terminal returns an control instruction to adjust operation of the pumping unit timely. According to the pumping unit intelligent control method, the remote control terminal sends the instruction to drive a field video acquisition unit to carry out video acquisition only when judging that the parameters acquired by the pumping unit terminal exceed a normal threshold value range; video data acquired in real time are used as a verification method for the abnormal parameters; therefore, shut down loss due to the fact that the remote control terminal sends a wrong instruction to the pumping unit because of failure of a sensor unit can be avoided, and transmission flow waste caused by timed video data transmission at ordinary times can be avoided.

Description

technical field [0001] The invention belongs to the technical field of remote control of an oil pumping unit, and in particular relates to an intelligent control method for an oil pumping unit. Background technique [0002] How to carry out real-time and effective remote monitoring of pumping units has always been a key issue in the field of oilfield technology research. A complete oil well remote control system should not only monitor multiple real-time oil well electrical and mechanical parameters, but also need to transmit the video data stream of video monitoring. In the existing technology, parameters and video data are collected continuously, and Send these data to the remote control terminal. However, the video data is usually huge, and the transmission process is relatively slow, and in the normal operation state of the pumping unit, the on-site video data usually does not have too high collection significance, but it consumes a huge amount of traffic during transmi...
