Abstract

The utility model relates to an integrative wireless monitoring indicator belonging toe technical field of mechanical oil production, which is mainly characterized in that a sensor is integrated with a secondary instrument, and the integrative wireless monitoring indicator comprises a radio transmitting module, a USB interface, a 485 interface, a rechargeable cell and a solar battery-board. The integrative sealing structure of the integrative wireless monitoring indicator can adapt complex outdoor environment and only need to be directly arranged on the polish rod of the upper end of a rope hanger, without the need of charging; the integrative wireless monitoring indicator can preserve a large quantity of indicator diagrams, read historical data or measure in real time through the wireless mode, review indicator diagram and detect series network, and create condition for the automatic detection of the oil well.

Description

Integrated wireless monitoring indicator

Technical field

The utility model relates to a kind of detecting instrument in the mechanical oil recovery technical field, relates in particular to the integrated wireless monitoring indicator that the sucker rod pump surface dynamometer card is detected.

Background technology

In the oil field of mechanical oil recovery, sucker-rod pumping well ground polished rod merit figure, or be called the pith that measuring of indicator card is the daily production management of oil well, be analyze, a diagnosis pumpingh well normal key index whether.The production status of pumpingh well is very complicated, and oil well pump is a lot of in the influence factor of underground work, and the merit figure that directly measures downhole pump is very difficult.Want to understand the working condition of pump, only analyze, diagnose at ground survey polished rod merit figure by means of indicator in the down-hole.The present primary instrument generally formed by load, displacement transducer of oil field indicator commonly used and constitute by the secondary meter that data acquisition unit is formed.Displacement transducer in the primary instrument adopts the mode of backguy, by pull out, exhausting line detects the polished rod displacement, spring-mass in its going barrel, pretension size directly influence its measuring accuracy, and adopt cable transmission data between primary instrument and the secondary meter, power supply adopts the mode of charge power supply, not only volume is big, part is many for whole instrument, installation is loaded down with trivial details, and the capacity of data storage is also limited.

Summary of the invention

The purpose of this utility model is at existing indicator above shortcomings, provides that volume is little, the storage data amount is many, helps a kind of integrated wireless monitoring indicator of continuous real-time monitoring.

The purpose of this utility model is achieved through the following technical solutions, a kind of integrated wireless monitoring indicator, comprise the master controller in box body and the box body, and signal conditioning circuit, real time clock circuit and data storage circuit, it is characterized in that intrinsic load sensor on the box body, its transducing signal inserts the input of modulate circuit, the intrinsic emission of box body one side is wireless, the front of box body is provided with solar panel, also is provided with MEMS micromechanics electronic chip and auxiliary circuit thereof, power control circuit, rechargeable battery in the box body; The induced signal of the displacement transducer that MEMS micromechanics electronic chip and auxiliary circuit thereof constitute inserts modulate circuit; The interface module end of master controller is provided with wireless transmit communication module, USB interface and 458 interfaces, and antenna is penetrated in the output sending and receiving of wireless transmit communication module; Rechargeable battery and solar panel provide electric energy for each load, and power control circuit is serially connected in each load power source loop.

The utility model is designed to multiple sensors, power supply and data processing, collection, storage, wireless transmitting system not to have the integrated apparatus of sealing fully of mechanical transmission, no transmission line, solar panel is set, both can be the rechargeable battery charging, and can be each load power supply again; The displacement transducer that adopts MEMS micromechanics electronic chip and auxiliary circuit thereof to constitute can be responded to the variation of polished rod acceleration, thereby determines the change in displacement of polished rod; The wireless transmit communication module is set, realizes the data wireless transmission of oil well indicator card, made things convenient for the diagnosis of data acquisition and oil well; USB interface is set, conveniently gathers, store mass data, realize the function of common flash disk image data; 458 interfaces are set, realize many instrument networkings.The incorporate hermetically-sealed construction of the utility model, can adapt to complicated outdoor environment, only need be directly installed on the polished rod portion of oil well polished rod eye upper end, need not its charging is waited maintenance, can automatically preserve a large amount of indicator cards by setting, when measuring the oil well indicator card if desired, use the PDA palm PC, just can at any time the oil well historical data be read and measure in real time by wireless mode, diagnosis, also the USB flash disk in the box body can be taken out and carry out merit figure playback, the utility model to the oil well networking, detects created condition for realizing the oil well automation owing to adopt the Wireless Networking mode.
