Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model positioning device circuit diagram.
Embodiment
In conjunction with the accompanying drawings the utility model is further described:
As Fig. 1, shown in Figure 2, on spool 2 tops of stretching out valve body 1 driving mechanism that is made of retarder 10 and stepping motor 7 is installed, the cup-shaped grating 8 of opening towards valve body 1 is installed on the spool 2 between valve body 1 and the driving mechanism 3, on described valve body 1, be separately installed with the transmitting terminal 6,6 ' and receiving terminal 6,6 ' of two photoelectric sensors corresponding to cup-shaped grating 8 inside and outside both sides.Cup-shaped grating 8 is slightly larger than the spacing of two photoelectric sensors corresponding to a raster width of multiport valve reference point locations, and all the other raster widths equate with the spacing of two photoelectric sensors, also with the grid of cup-shaped grating 8 between spacing equate.Be carved with 360 grids on the described cup-shaped grating 8, the running accuracy of spool 2 is 1 degree, and when the grid number of cup-shaped grating 8 was 720, then the running accuracy of spool 2 became 0.5 degree.Precision according to actual needs, the grid number can be done corresponding variation.
During work, the cup-shaped grating 8 that is fixed on the spool 2 rotates synchronously with spool 2, make two optoelectronic switch outputs and the corresponding pulse signal of spool 2 rotating speeds, because cup-shaped grating 8 is slightly larger than the spacing of two optoelectronic switches corresponding to the raster width of automatic multiport valve reference point locations, when spool 2 turns to reference point, two optoelectronic switch outputs are all high level, signal is sent to the position probing be made up of engineering machine or single-chip microcomputer and position control 4 as with reference to the point location signal, because the spacing of two optoelectronic switches equates with all the other raster widths of cup-shaped grating 8, also with the grid of cup-shaped grating between spacing equate, therefore spool 2 turns to non-reference point locations, it is 90 ° that the pulse of two optoelectronic switch outputs differs, through exporting behind special-purpose 11 pairs of two-way pulses of phase discriminator chip phase demodulation, turn to corresponding one tunnel level signal to export position probing and position control to spool 2 as the direction identification signal, another road dashes as the meter rapid pulse, by position probing and position control 4 accumulated counts.Simultaneously spool 2 desired location in the middle of position probing and position control 4 the rotation control instruction that the operator is sent are converted into the strokes per minute of corresponding meter rapid pulse, and this result and photoelectric sensor meter rapid pulse compared towards the signal accumulated value, calculate the location compensating parameter, calculation of parameter goes out stepper motor 9 rotation directions and the corner of spool 2 location compensating movements thus, and make corresponding compensation by position probing and position control 4 output control signal corresponding with drive stepping motor 9 and rotate, thereby spool 2 can accurately be located in operation process.In addition, position probing and position control 4 can whether normal parameter monitors automatic multiport valve as stepper motor 9 output torques according to the fast pulsation rate of the meter of photoelectric sensor, in case the moment of torsion abnormal conditions occur, position probing and position control 4 can send warning message.Position probing and position control 4 also can be according to after sending the motor rotation control signal, if after certain time-delay, two photoelectric sensors still do not have photoimpact output, and the equipment that then is considered as produces hard fault and sends alarm signal.
