Description
Technical field
The present invention relates to a kind of high precision oil pumper wireless indicator and load-position diagram measuring method thereof.
Background technology
Oil pumper wireless indicator in the market as shown in Figure 1, by acceleration transducer 1 ', pressure type load transducer 2 ', collection of simulant signal module 3 ', digital signal main control module 4 ' and wireless signal transceiver module 5 ' form, the specific implementation flow process is: after being received outside upper layer device requirement and measured the order of load-position diagram of oil pumper one-period by wireless signal transceiver module 5 ', pass to digital signal main control module 4 ', digital signal main control module 4 ' controls acceleration transducer 1 ' and pressure type load transducer 2 ' is opened, measure one-period (cycle is to calculate gained according to the motor speed of oil pumper), the simulating signal of both output passes to digital signal main control module 4 ' after being processed by collection of simulant signal module 3 ', in the measurement in whole cycle, digital signal main control module 4 ' is no less than preservation load and the acceleration information group of 200 points, then according to twice integration of accekeration, obtain the shift value of initial each savepoint, and need by the oil pumper cam curve, the numerical value such as lever arm ratio, revise out the correct shift value of each savepoint, finally by wireless signal transceiver module 5 ', send to outside upper layer device.
Such wireless indicator diagram measuring method has adopted the pressure type load transducer on the one hand, and its load measurement precision and long-time stability are greatly affected; Adopted on the other hand twice integration of acceleration transducer to ask the method for displacement, the displacement measurement precision is also very low, this be because: one, oil pumper, in the course of work that moves up and down, has the interference such as vibration, lateral rotation substantially, causes measured accekeration itself that very large error is just arranged; Two, due to the problem that is disturbed of acceleration analysis, the analog or digital filtering of being compelled to do on electrical design is processed, must cause institute's measuring acceleration value to have phase place to lag behind and amplitude attenuation, just can't synchronize with the load data retention time, this has brought error very large on the overall performance for the load-position diagram finally drawn out; Three, move up and down speed when slower when oil pumper, the changing value of acceleration is also very little, causes signal to noise ratio (S/N ratio) greatly to reduce and can't correct measurement.
