Description
Technical field
The utility model belongs to step-by-step counting field of instrumentation technology, particularly relates to a kind of signal conversion and driver module of counter.
Background technology
At present, the known counter of using the power supply of two-wire system square-wave pulse signal and showing the pulse number of counting with digital wheel, its drive part can adopt electromagnet.When measured pulse signal is connected, electric current flows through electromagnet coil to produce magnetic field, and electromagnetic actuation drives ratchet, and ratchet streaks a tooth on ratchet, and now, metal spring is also pulled and in energy storage state.When pulse signal disappears, electromagnet coil power-off, magnetic field disappears, and electromagnet discharges, and metal spring resets, and drives ratchet, and ratchet promotes ratchet and rotates a tooth, and digital wheel just records next number.When passing to N pulse signal, said process just carries out N time repeatedly, and digital wheel just records N number.
Such device needs metal spring must have enough power when location and driving ratchet, and guarantee reliable operation, also needs electromagnet to have enough large electromagnetic attraction to go to overcome the power of metal spring on the other hand like this, and this is conflict.As reliable in guaranteed counter works, power consumption will be large relatively, cause electromagnet heating, and by flexible member location, shock resistance be not high.
As shown in Figure 1, the drive part of above-mentioned counter also can adopt single-phase permanent formula stepping motor (below referred to as " stepping motor ").The advantages such as it is little that stepping motor has volume, low in energy consumption, and shock resistance is good, its shortcoming is that stepping motor rotor magnetic pole is a pair of utmost point, on 360 ° of circumference, magnetizes into a N utmost point, a S utmost point.In cold situation, the position that rotor stops is random, and the position of magnetic pole of rotor is random (as shown in Fig. 1 (a), (b), the magnetic pole of rotor can be the left side N utmost point, and the right S utmost point can be also the left side S utmost point, the right N utmost point).Suppose that rotor original position is as shown in Fig. 1 (a), when first pulse comes then, the magnetic pole same polarity that the magnetic pole of rotor and pulse signal produce by stator coil (as Fig. 1 (c)), rotor rotation 180 degree arrive as the position of Fig. 1 (d), and if the home position of rotor is as shown in Fig. 1 (b), when first pulse comes then, the magnetic pole reversed polarity that the magnetic pole of rotor and pulse signal produce by stator coil, rotor is motionless, to second negative pulse, come, rotor ability turnback, as shown in Fig. 1 (e), (f).
In these cases, a corresponding input pulse, rotor only rotates 180 °.No matter timer or counter, when driving with stepping motor, just all exist after first pulse input, and likely the stepping motor first step is not walked.Concerning timer, if error requirements is not tight, actual use is unaffected, but will cause loss of data concerning counter.
