Method and system for remote encryption control of oil pumping unit

Abstract

The invention discloses two remote encryption control methods for a pumping unit and a control system thereof. Signal processing is respectively carried out on oil well electric data, mechanical parameters, and video data and then encryption processing is carried out on the processed data and parameters, wherein the oil well electric data, the mechanical parameters, and the video data are detected by a pumping unit terminal; the processed information is transmitted to a server by a 4G communication network or a 3G communication network; and after the obtained information is analyzed by the server, control data are returned to a pumping unit side so as to realize secure and reliable remote controlling of the pumping unit. According to the first kind of remote encryption control method for the pumping unit, when data transmission is carried out, encryption processing is carried out in advance and deciphering operation is carried out at a server terminal to read the data; and the whole data transmission process is secure and reliable and data leakage is prevented. According to the second kind of remote encryption control method for the pumping unit, before data are stored, encryption processing is carried out on the data, so that the stored data can not be read randomly at the pumping unit terminal and the deciphering operation is only carried out by a corresponding deciphering module at the server terminal. Therefore, security of data transmission is ensured; and filed enclosing of data acquisition can be realized and filed data leakage of the pumping unit can be prevented, so that the security is high.

Description

technical field [0001] The invention belongs to the field of remote control technology and encryption technology of an oil pumping unit, and in particular relates to two remote encryption control methods and systems for an oil pumping unit. Background technique [0002] Mastering the energy consumption of various equipment is an important part of strengthening the management of energy consumption. The pumping unit is an important production equipment in the oil field, and it is also a large energy consumer. It is the focus of oil field production management and energy saving and emission reduction. According to the statistics of the China Petroleum Industry Association, the number of pumping units in China is 100,000, and the annual increase is 5,000; the total capacity of the pumping unit motor is 3500MW, the annual power consumption exceeds 10 billion KWh, and the efficiency is 20-30%, which is the domestic average. It is 25.96%, and the foreign average is 30.05%, so the ...

Problems solved by technology

[0003] Due to the remote location of the pumping unit, the operating status of the pumping unit must be monitored through a remote monitoring system. During monitoring, a large amount of data must be transmitted back to the remote server, and the security of data transmission is usually not guaranteed. Sometimes data records must be left on the pumping unit side. Since the pumping unit is sometimes unsupervised, the data on the pumping unit side is also in an open state, which is extremely unsafe
