Abstract
The utility model discloses an automatic digital signal detector for times of stroke of a petroleum pumping unit. A Hall proximity switch (3) of the detector is mounted on one side surface of a connecting rod (5) of the pumping unit; a magnet (2) is mounted in a position in a crank (6) of the pumping unit, which is opposite to the Hall proximity switch (3); signals of the Hall proximity switch (3) are connected into a data processing module (4); data transmission is conducted between the data processing module (4) and a control center (8) through a wireless network (7); a detection result is transmitted by the data processing module (4) to the control center (8) through the wireless network (7); and belt tightness degree of a transmission belt of the pumping unit is calculated by the control center (8) according to detected times of stroke in unit time, so as to judge whether the pumping unit works normally or not. The automatic digital signal detector has the advantages that detection data are accurate and reliable, manual operation is not needed and the safety is high.
Description
Technical field
The utility model relates to a kind of petroleum extractor jig frequency signal supervisory instrument, particularly relates to the automatic digital signal detection appearance of a kind of petroleum extractor jig frequency.
Background technology
At present the oil field understand and grasp oil well whether the mode of operate as normal be to adopt the on-the-spot patrol of manual regular, check with the mode of range estimation whether oil well shuts down.The oil field that has also adopts the relevant parameter of artificial in-site measurement oil well to understand this mode of working condition of oil well.Adopt the defective of artificial patrol and artificial in-site measurement associated arguments to be: (one) poor reliability.Chief reason is that the source of information is not necessarily reliable, and human factor is too many, whether judges that in rotation whether an oil well is also in oil pumping such as the crossbeam of only seeing pumping unit of well.(2) real-time is poor.Owing to the manual regular patrol can't be consistent with the actual moment of breaking down, the slow excessively phenomenon of information that the oil well that therefore total existence obtains breaks down, the most serious delay can reach a patrol cycle.If increase oil field workman and patrol personnel's patrol number of times, then can increase the labour cost in oil field.(3) there is unsafe factor.Because of oil pumper all works in the field, and be irregular distribution, oil field workman and patrol personnel go to the scene check and the road measured in all have certain unsafe factor.Detection method is at present: the testing staff hands meter reading instrument, is stuck on the pumping-unit motor live wire, reads the meter reading instrument data presented.Detecting the petroleum extractor jig frequency with the method, to have the people be the inaccuracy of the measurement result that causes, and there is electric shock in the testing staff, collides unsafe factor such as oil pumper crossbeam in testing process simultaneously.
The petroleum collection industry petroleum extractor jig frequency number of measuring commonly used calculates the elasticity of oil pumper driving belt, if the jig frequency number can not accurately be measured, then can not obtain the result of calculation of belt elasticity accurately.Therefore, adopt the automatic digital signal detection appearance of a kind of petroleum extractor jig frequency to have stronger application demand.
Summary of the invention
In order to overcome the above-mentioned deficiency that prior art exists, the utility model provides a kind of petroleum extractor jig frequency automatic digital signal detection appearance.This utility model can accurately be measured the jig frequency number of times of petroleum extractor in real time, need not manually-operated, and it is reliable, safe to detect data.
The utility model solves the technical scheme that its technical problem adopted: the automatic digital signal detection appearance of a kind of petroleum extractor jig frequency; Comprise magnet, proximity Hall switch, data processing module and control centre; Said proximity Hall switch is installed in oil pumper connecting rod side; Magnet is installed in position relative with proximity Hall switch on the oil pumping machine crank; The signal of proximity Hall switch inserts data processing module, carries out transfer of data through wireless network between data processing module and the control centre, and data processing module is sent to control centre with testing result through wireless network (7); The unit interval jig frequency number that control centre obtains according to detection calculates the belt elasticity of oil pumper driving-belt, thereby judges whether operate as normal of oil pumper.
Said data processing module is made up of signaling conversion circuit, counter and wireless transport module; The induced voltage signal that is sent to data processing module converts the digital quantity pulse signal into through change-over circuit; Accomplish counting by counter again, send to control centre after wireless network transmission module will record petroleum extractor jig frequency number.
The beneficial effect of the utility model is: use this device detect petroleum extractor jig frequency signal promptly and accurately, need not manually-operated, safe.

The specific embodiment
Embodiment
Fig. 1 is the automatic digital signal detection appearance of the disclosed a kind of petroleum extractor jig frequency of the utility model; Comprise petroleum extractor 1, magnet 2, proximity Hall switch 3, data processing module 4 and control centre 8; Proximity Hall switch 3 is installed in the side of oil pumper connecting rod 5; Magnet 2 is installed on the oil pumping machine crank 6; The position of the magnet 2 on the oil pumping machine crank 6 is corresponding with the position of oil pumper connecting rod 5 side proximity Hall switchs 3, and the signal of proximity Hall switch 3 inserts data processing module 4, carries out transfer of data through wireless network 7 between data processing module 4 and the control centre 8.Said data processing module 4 is made up of signaling conversion circuit, counter and wireless transport module; The induced voltage signal that is sent to data processing module 4 converts the digital quantity pulse signal into through change-over circuit; Accomplish counting by counter again, send to control centre 8 after wireless network 7 transport modules will record petroleum extractor jig frequency number.
When oil pumping machine crank 6 rotates to the relative position of magnet 2 and proximity Hall switch 3; The magnetic field that magnet 2 produces makes the Hall element of proximity Hall switch 3 produce an induced voltage; Induced voltage signal is sent to data processing module 4; Become the digital quantity pulse signal through amplification, filtering, level shifting circuit after changing successively, and accomplish once counting by counter.A moving week of crank 6 revolutions is accomplished once counting; Data processing module 4 is sent to control centre 8 with testing result through wireless network 7; The belt elasticity of oil pumper driving-belt is calculated by control centre 8 according to the unit interval jig frequency number that detects; Thereby judge whether operate as normal of oil pumper, and then assign the on-site maintenance personnel that oil pumper is safeguarded and keep in repair.
