The groundwork process of the digital intelligent winch panel in the utility model is as follows:

Two meter wheels rotations about on the cable of the going into the well drive depth-logger measuring appliance, revolution and rotating speed can be represented the following dark and speed of cable, with left and right sides meter wheel coaxial about two photoelectric encoders, convert corner to a, b two phase electricity pulse train, through IC25, IC22-1, IC22-4 carries out sending into counter IC3 after the frequency transformation, the signal of IC22-4 is used for redundancy ratio than usefulness, the signal of IC22-1 is used for the usefulness of dark counting down, the signal of IC22-1 also directly is sent to CPU and carries out computing, try to achieve speed, the degree of depth, send demonstration etc., the signal of photoelectric encoder also carries out phase-detection through IC24-2 and produces the lifting marking signal, this signal one tunnel is used to export to external instrument, and the usefulness of confession internal judgment liftings such as IC14 is sent on another road.IC14 periodically detects two tunnel signal-count values among the IC3, and whether judge between cable and the some meter wheels has skidding and eliminate it.

Because in use inevitable the generation gradually of cable amount wheel external diameter worn and torn, corresponding relation between the corner of the line length of cable and meter wheel is changed, produce measure error, when this error surpasses the technology permissible value, conventional method promptly will be changed or carries out size restoration meter wheel, in order to make meter wheel overproof or because foozle still can remain on measure error in the permissible value after overproof, the utility model has been introduced the error compensation function in wearing and tearing.What be implemented as follows: calculate 0.1 meter of every error of meter after learning measure error by certain mode, positive and negative with this meter number and error by manually sending into instrument from keyboard, after the IC14 computing, on the one hand from the degree of depth counting that shows with its correction, IC14 exports one road signal and handles the back by the compensating signal of IC19-4 output through error correction to the signal synthesis of IC19-4 and photoelectric encoder on the other hand, this compensating signal one tunnel is through IC23-1, the biphase signaling that becomes 1024 pulse/rice after IC23-2 handles is supplied with SL91 II digital logging recorder, another road is through IC19, IC18, IC20 etc. are processed into the biphase signaling of 400 pulse/rice and supply with the use of SL91 I digital logging recorder, IC14 judges whether super dark hypervelocity and whether arrives well head according to depth value, start sound and light alarm, after the degree of depth surpasses a certain value, closing relay J502 stops paying out motivation when cable cuts off J501 5 meters the time more than well head.

The amplifier of the adjustable multiplication factor that the signal that will be installed on the sky of well head or the tension pick-up on the lower sheave in the utility model is formed through IC13 amplifies back one tunnel and arrives IC7, another road is to IC12, in IC7, this signal is carried out digital translation, send into to send after IC14 carries out calculation process through IC6 and show and judge that whether tension force is above giving the data of putting, determine whether disconnecting J501 and stop paying out motivation, and produce sound and light alarm; Signal with IC13 output in IC7 carries out exporting tension signal for outside use after the scale operation filtering, IC14 makes tension increment table ZLB deflection with the indication tension increment after sending IC5 to simulate conversion the tension force variable, can return zero by manually-operated, the self-zeroing of also can delaying time after the increment list outrange.When tension pick-up is loaded on top sheave, cable is 0 ° to the wrap angle of pulley, the wrap angle of cable is relevant with the position of winch in the time of on being installed on lower sheave, in 85 °～140 °, because the signal of tension pick-up is the function of cable stretch and 0 jiao, so need send into 0 value by the IC14 computing, the utility model has been abandoned and traditional has been selected 0 jiao method with band switch, directly sends into keyboard.

In order to guarantee the reliably working of IC14, formed the sequential monitoring device by IC17.When IC14 normally moves, issue a signal to IC17, when by IC17 IC14 is resetted to recover its operate as normal when unusual appears in this signal through IC4c end.

Because having a power failure suddenly, AC power still can make instrument keep data for guaranteeing at work, formed power sense circuit by IC16, when having a power failure, produce signal INTO and make it enter the power down process program, keep data to quit work to IC14 by IC26, IC11-3.This moment, data memory was by battery BT power supply, and minimal power consumption, BT are rechargeable battery, at ordinary times by the V1 charging, can go into dc battery jar power supply between the 15-24V by the external power supply termination when exchanging when having a power failure also, and instrument is normally worked on.

Digital intelligent winch panel in the utility model provides the communication function of the sound equipment between instrument cab and the winch, when with communication termination power ground, but loudspeaker Y S sounding, YS is also as the usefulness of other warning of instrument, the audio signal of YS is that the output signal frequency division by IC7 obtains, and IC14 is by its alarm sound of c end control of IC4.

Low energy-consumption electronic device and scheme have all been adopted in the circuit devcie of the digital intelligent winch panel in the utility model and design, and power supply power consumption can improve the functional reliability of instrument less than 5W.

The on-the-spot environment for use of the utility model is more abominable, and waterproof and dampproof preferably performance must be arranged, and advanced film face-plate has been adopted in the instrument front portion for this reason, and is corrosion-resistant, anti-aging, attractive in appearance, good leak tightness.Touch button and be loaded on below the film, make it hermetically sealed, all fill bonding surface with silicone grease during installations such as the socket on the operation panel, gauge outfit, switch, the structure week of whole casing has thickly been considered waterproof problem.

Winch is on-the-spot when using, and extraneous light is stronger, and is big with common light-emitting diode display power consumption, brightness is low, is difficult to meet the demands.And LCD display price height, need external light source and poor performance at low temperatures night again, adopt fluorescence display, brightness height, power consumptive province, and added Filter and light shield in the above, and on circuit, added single parameter Presentation Function again, it is only scanned show a few bit data, further improve brightness, satisfied on-the-spot instructions for use.
