Remote monitoring device for early warning of pumping unit failure

Abstract

The invention discloses a fault early warning and remote monitoring device for an oil pumping unit and relates to a monitoring device. The fault early warning and remote monitoring device is composed of a rotary sensor, an electric current sensor, a voltage sensor and a monitoring terminal. The rotary sensor is installed in the position, under a crank device of the oil pumping unit, of a base of the oil pumping unit. The electric current sensor and the voltage sensor are installed on three-phase power lines inside a power distribution box of the oil pumping unit. The monitoring terminal is arranged on a rack of the oil pumping unit and comprises a machine shell, a display screen installed on the machine shell, an ARM processor, a CAN transceiver and a power source, wherein the ARM processor, the CAN transceiver and the power source are installed in the machine shell. The ARM processor is connected with the CAN transceiver, the display screen and a power circuit. The CAN transceiver is in circuit connection with the electric sensor, the voltage sensor, the rotary sensor and a plurality of expansion interfaces through a physical bus. According to the fault early warning and remote monitoring device for the oil pumping unit, a bus mode is adopted, the reliability is high, the functions of the device can be expanded as required based on the bus, and the operation condition of the oil pumping unit can be remotely monitored.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a remote monitoring device for failure early warning of an oil pumping unit. Background technique [0002] With the continuous development of the petroleum industry, there are more and more facilities such as oil wells, drilling platforms, and oil production plants. However, in order to ensure safe production, managers need to conduct regular well inspections. This not only takes time and effort in management and maintenance, but also increases labor costs and Due to the labor intensity of workers and the use of manual inspections, if the workers are slack or negligent, they cannot accurately grasp the working status of each well, and cannot detect failures in pumping units and motors in time, and cannot effectively monitor, prevent and control them. With the increase in the number of oil wells, this model is no longer suitable for production needs. Contents of the invention [0003] The...

[0002] With the continuous development of the petroleum industry, there are more and more facilities such as oil wells, drilling platforms, and oil production plants. However, in order to ensure safe production, managers need to conduct regular well inspections. This not only takes time and effort in management and maintenance, but also increases labor costs and The labor intensity of the workers, and the use of manual inspections, if the workers are slack or negligent, it is impossible to accurately grasp the working status of each well, and the failures of the pumping units and motors cannot be discovered in time, and effective monitoring, prevention and control cannot be achieved.
