Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described. Obviously, described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Embodiment 1
As shown in Figure 1, present embodiment discloses a kind of vending machine shipment motor control assembly, including the shipment motor 20 being electrically connected with power supply 10, sample resistance 30 it has been arranged in series between power supply 10 and motor 20, it is provided with the current detection circuit for detecting electric current at the two ends of sample resistance 30, between power supply 10 and motor 20, is additionally provided with the control circuit for being turned on and off motor 20.
The concrete two ends at sample resistance 30 are connected with discharge circuit 41, and the outfan at discharge circuit 41 is electrically connected with A/D change-over circuit 42 and single-chip microcomputer 43 successively. Discharge circuit 41, A/D change-over circuit 42 and single-chip microcomputer 43 form current detection circuit. Being arranged in series motor drive ic 44 between power supply 10 and motor 20, the control end of motor drive ic 44 and single-chip microcomputer 43 are electrically connected, motor drive ic 44 and single-chip microcomputer 43 composition control circuit.
The current value size that Current amplifier to the single-chip microcomputer 43 at sample resistance 30 place can be detected by discharge circuit 41, and by A/D change-over circuit, current value is converted to the data suitable in single-chip microcomputer 43, single-chip microcomputer 43 receives the current value of discharge circuit 41 transmission, and compares with the current value set. Through comparing, if be detected that electric current is greatly beyond the electric current of the normal operation set, illustrate that motor rotation is abnormal, now single-chip microcomputer 43 controls motor drive ic 44, and motor drive ic 44 closes motor, reaches the effect of protection motor, instruction beamed back by single-chip microcomputer 43 simultaneously, the main frame shipment failure of announcement;If be detected that electric current less than the electric current of normal operation set or is not detected by electric current, illustrating that motor 20 is abnormal, motor does not work, and now instruction beamed back by single-chip microcomputer 43, and the main frame shipment of announcement is unsuccessfully.
