Description

A kind of wireless oil well indicator

Affiliated technical field

The present invention relates to a kind of surveying instrument, the indicator that especially a kind of oil well is used.

Technical background

Measure indicator diagram of pumping well and be analyze, diagnosis rod-pumped well normal a kind of effective means whether, also be a pith of well on the beam daily management mission.The load of being born on the different displacement place sucker rods when indicator periodically moves up and down by detecting sucker rod reflects the working condition of oil well.The backguy method is generally adopted in the measurement of displacement at present in the indicator, and signal adopts cable transmission, and the lead-in wire of instrument moves with polished rod.This measuring method principle is simple, and precision is higher, and shortcoming is that volume is big, and mechanical part is many, processed complex, the on-the-spot inconvenience of using.

Summary of the invention

The objective of the invention is to avoid the deficiencies in the prior art and utilize the device of acceleration transducer Displacement Measurement demonstration measurement oil well load-position diagram.

The technical solution adopted in the present invention is: a kind of wireless oil well indicator, comprise acceleration transducer, power module DSP single-chip microcomputer, wireless communication module, display, PC, power module is connected with the DSP single-chip microcomputer with acceleration transducer, acceleration transducer is connected with the DSP single-chip microcomputer is unidirectional, the DSP single-chip microcomputer is connected with wireless communication module is unidirectional, display is connected with the DSP single-chip microcomputer is two-way, and wireless communication module is connected with PC is unidirectional, and the DSP single-chip microcomputer is provided with serial port.

Acceleration transducer comprises cell sensor, self-checking circuit, integrator, amplification filtering circuit, temperature-compensation circuit, steering logic and eeprom circuit, oscillator, clock generator, cell sensor is connected with eeprom circuit with steering logic by self-checking circuit, integrator is connected with eeprom circuit with steering logic with oscillator by clock generator, temperature-compensation circuit is connected with eeprom circuit with steering logic respectively with the amplification filtering circuit, and the interface of steering logic and eeprom circuit is connected with the DSP single-chip microcomputer.

Compared with prior art, advantage of the present invention is to measure accurately, and convenient the use is safe and reliable, not only can be used for the measurement of other cyclical movement relative displacement, can also measure the speed of motion simultaneously.
