With reference to figure 3, photoelectric tube VD includes a light emitting diode and a phototriode, light emitting diode send light
Light-reflecting components on signal to rotor 21, the light-reflecting components that phototriode can be received from rotor 21 reflect
Optical signal, phototriode turns under the action of optical signal so that by the first output terminal output pulse signal, and because
Rising edge and the trailing edge ratio of the pulse signal are shallower, then the more pulse signal of standard in order to obtain, in order to processor
Pulse signals are handled, then the edge of pulse signal are become precipitous by the comparator B in Fig. 3, then comparator B is defeated
Go out the pulse signal of standard to processor so that processor can pulse signals handled, rotate a circle so as to obtain motor
Required time and motor rotating frequency.
Light emitting diode passes through current-limiting resistance R1 the first level output ends of connection V1 so that light emitting diode VD shines, light
Quick triode is by current-limiting resistance R2 connection the first level output end V1, so that photoelectric tube VD obtains operating voltage, the
One level output end V1 produces second electrical level output terminal V2, second electrical level output terminal V2 by current-limiting resistance R3 and current-limiting resistance R4
The magnitude of voltage of the second electrical level signal of output is slightly smaller than the magnitude of voltage of the first level signal of the first level output end V1 outputs, light
The magnitude of voltage that the magnitude of voltage for the pulse signal that electricity exports the first output terminal of pipe VD exports if more than second electrical level output terminal V2,
Then comparator B exports low level, conversely, comparator B exports high level, comparator B exports undersuing extremely by output terminal
Processor, while the output terminal of comparator B obtains appropriate magnitude of voltage by pull-up resistor R5 undersuings.Also,
By adjusting current-limiting resistance R3 and current-limiting resistance R4, the big of the second electrical level signal that second electrical level output terminal V2 is exported can be adjusted
It is small, so that the precision of undersuing be adjusted.

Supply voltage needed for die trial block and processing module, for example, above-described first level output end V1 is then power module
Output terminal, it is exemplary, as shown in figure 4, Fig. 4 is the electrical block diagram of power module provided in an embodiment of the present invention.Core
Piece U1 is used to produce the operating voltage suitable for test module by total voltage：First level signal.Total voltage output terminal V_BUS
Whether the first level signal is produced by selecting switch S1 control chips U1, and by the first level output end V1 by the first level
Signal is delivered to test module, and when selecting switch S1 is connected with the input terminal V_IN and Enable Pin EN of chip U1, chip U1 leads to
Cross output terminal V_OUT output the first level to the first level output end V1.Capacitance C1 is used to be filtered total voltage in processing, core
Contain voltage stabilizing pressure unit in piece U1, for producing the first level signal less than total voltage, and pass through capacitance C2 and capacitance C3
Reduce the noise of the first level signal of output.Certainly, the operating voltage of test module and processing module can also be by other
Circuit obtains, and the present embodiment is only illustrated with above-mentioned example.
Processing module is handled except the pulse signal for test module to be exported, and is obtained rotor and is turned over one week
Time and motor speed, optionally, the processing module can be also used for the rotating speed according to corresponding motor, and set
Determine threshold value to be compared, and comparative result is exported and is shown.Specifically, between processing module calculating pulse signal each two square wave
Time interval, and be compared with given threshold, if difference is more than setting difference, illustrate that the motor performance is unqualified, if
Difference then illustrates motor qualification no more than setting difference.For example, if motor rotation 60 in one minute switchs to eligible state, often
Turn time interval should be 16.7ms, if the time interval between the square wave optical signal detected be 16.7ms ±
0.01ms, then it is assumed that performance is qualified, whereas if the time interval between two square waves detected not 16.7ms ±
In the range of 0.01ms, then it is assumed that motor performance is unqualified.
