Problems solved by technology

[0003] At present, most of the beam pumping units use manual adjustment of the balance of the pumping unit. Some manufacturers use a wired connection to connect the balance weight control device to the controller in the ground control cabinet. Other manufacturers use wireless communication. The way to connect the balance weight control device to the ground control cabinet, currently there are balance weight control devices that provide wireless interfaces on the market, but there is no matching ground control device that together form a complete balance adjustment system

Abstract

The invention belongs to a tail walking beam ground control device which comprises a micro controller, wherein an I2C bus interface of the micro controller is electrically connected with an EEPROM memory; an SPI bus interface of the micro controller is electrically connected with a special three-phase electric energy metering module; I / O ports of the micro controller are respectively and electrically connected with a switching quantity input unit and a switching quantity output unit; two USART serial bus interfaces of the micro controller are respectively and electrically connected with a WIFItransmission module and a ZigBee communication module; and the other two USART serial bus interfaces of the micro controller are respectively and electrically connected with an RS485 bus level conversion module. Two communication modes are provided for connecting a tail walking beam balance block control device so as to form a complete balance degree regulating system. By providing a wireless connection mode, the system fault caused by cable fracture due to reciprocating movement of a sucker rod can be effectively avoided; meanwhile, potential safety accidents caused by electric leakage is avoided; and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the technical field of pumping units, in particular to a ground control device for a tail beam. Background technique [0002] Beam pumping unit is a kind of ground power transmission equipment widely used in oil production. The rotary motion of the power machine is converted into the reciprocating motion of the sucker rod and the oil well pump through the reduction box and the crank connecting rod, so as to realize the oil suction and oil discharge process of the oil well pump. In the production of oilfields, due to the continuous change of reservoir conditions, the beam pumping unit needs to be adjusted frequently to ensure that the load on the pumping unit’s up and down strokes is even, prolonging the service life of the equipment and reducing energy consumption. [0003] At present, most of the beam pumping units use manual adjustment of the balance of the pumping unit. Some manufacturers use a wired connection to connect t...
