In conjunction with Fig. 2, Fig. 3, Fig. 4, in an embodiment of the present utility model, as shown in figure 4, driver corresponding interface A
Match with encoder A, in order to identify whether driver correctly connects encoder A, in the company of encoder A and driver interface A
Meet setting marker element A in circuit, in an application examples, using the resistance R1 for 1K for the resistance.Wherein, the interface electricity of driver
The resistance R2 on road is 20K.When control circuit sends 5V_EN signal, the switching off of interface circuit, R1, R2 form series winding electricity
Road.Principle according to series circuit electric resistance partial pressure is it can be deduced that the voltage of the resistance R1 matching with encoder A is U1=5V*
R2/ (R1+R2)=0.23V, if ignoring the load of encoder A, the supply voltage (VCC-GND) of encoder A input is about
0.23V, if considering encoder load, the voltage of VCC-GND should be less than equal to 0.23V.Because encoder is in extremely low power supply electricity
Pressure, inside chip all fails work, externally assumes higher impedance, substantially the intrinsic standoff ratio of R1 and R2 is not impacted.
When on the interface A that encoder A is connected to driver, control circuit sends 5V_EN signal, the switching off of interface circuit, R1,
R2 forms series circuit, and control circuit provides 5V voltage, and driver, by way of A/D samples, is read by testing circuit
The magnitude of voltage of ENCODER_DET, if the result reading is less than or equal to 0.23V, illustrates what this marker element R1 was connected
Encoder A is mated with the interface A of driver, and driver is correctly connected with encoder.The control circuit of driver then controls 5V_
EN signal, opens interface circuit switch.Export 5V power supply to encoder A, enter life's work pattern.
In the same manner, marker element B is set in the connection circuit of encoder B, and such as resistance value is the resistance R3 of 5K.When coding
Device B is connected on the interface A of driver, and the magnitude of voltage recording ENCODER_DET by testing circuit is 1V, more than 0.23V,
Then illustrate that the encoder B and driver interface A that this marker element R3 is connected mismatches, the warning circuit of driver sends warning
Information reminding user, and continue to monitor, stop alarm after driver interface A connects correct encoder, control 5V_EN
Signal, opens the switch of interface circuit, exports 5V power supply to encoder, enters life's work pattern.
It should be noted that in above-described embodiment, the value of resistance R1 and R2 can arbitrarily be arranged, R1 is permissible for each resistance
The encoder of the same model of unique mark, by adjusting the size of R1, can identify different coupling encoders.This practicality
The new marker element being connected to not only by detection in driver, encoder or connection circuit between the two, confirms
Whether the interface of driver is mated with encoder, may recognize that encoder is not connected with or connects insecure mistake, it is former
Reason is as above.
