Research on Sucker Rod Displacement Measuring Technology Based on Double Integral of Acceleration

Abstract:

In allusion to the disadvantages of sucker rod displacement measuring technologies at present, we introduce an inertial measuring technology in which the design of acceleration measuring system, the design of IIR digital filter and double integral algorithm play significant roles. Through combination of hardware and software, the embedded measuring system was developed to measure the acceleration, process data and realize the serial communication. In our practical work, some chips were used in this system, eg 1221L-002, ADS1259, MSP430F1611, MAX202, etc. The test results showed that the accuracy of the measuring system reached to 5%, which met the request for oilfield.
