Abstract
An integrated wireless data system and method for controlling and measuring operational data of a pumpjack system, for safety, health monitoring, and pump control is provided. The integrated wireless data system and method may be configured to allow for bi-directional communication with a central station to enable human intervention with pumpjack and to store pump parameters in a database for use in development of predictive maintenance techniques.
Claims13
An integrated wireless data system for measurement of operating characteristics of a pumpjack, comprising:
- a remote unit mounted to the pumpjack having at least one sensor and a remote transceiver and an amplifier and an A/D converter and at least one low impedance switch and a microprocessor and an energy harvesting device for measuring data associated with the operational characteristics of the pumpjack;
- said remote unit including a power storage device connected to and providing power to said remote unit;
- a base unit located in a motor control panel of the pumpjack having a base transceiver and an amplifier and a microprocessor connected to and in communication with a motor controller for controlling a motor of the pumpjack;
- a central station having a central station transceiver and an amplifier which is connected to a PC for the purposes of storing and analyzing the data measured by said remote unit;
- and
- said remote unit and said base unit and said central station wirelessly communicate with one another to exchange the data in real-time bi-directionally.
A method for measuring operating characteristics of a pumpjack under real-world operating conditions, comprising the steps of:
- installing a remote unit on a component of the pumpjack;
- measuring the operational characteristics of the pumpjack using the remote unit;
- wirelessly transmitting the operational characteristics to a base unit located within a motor control panel of the pumpjack;
- converting measured strain measurements to at least one of an orthogonal bending and an axial strain and a torque of the component of the pumpjack;
- and
- compensating the operational characteristics for temperature effects.
A method to configure an integrated wireless data system including a base unit in wireless communication with a remote unit and with a central station to download and analyze data collected by the integrated wireless data system, comprising the steps of:
- collecting data using the remote unit and the base unit of the integrated wireless data system;
- downloading the data from the central station onto a PC;
- and
- storing the data in a database on the PC for historical analysis.
