Wherein, described control unit 6 accordingly controls described according to the on off operating mode of three Operation switches SW1, SW2, SW3 The flow chart of driving circuit 7 or the switching mechanism 4 can be found in Figure 14:

Execute step S11: the moving head is arranged to default and rests on position of beating the grass.Execute step S12: when detecting When being triggered around wiretap SW2, execute step S13: control unit 6 controls the stand-by motor in position switching mechanism, auxiliary electricity Machine drives the head capsule of grass-mowing machine by gear-rack drive bluff piece, and grass-mowing machine is made to go to winding position.Step S13: key press time Greater than T1S, at this point, execute step S15, control unit 6 can synchronously control driving circuit 7 so that motor reversal is carried out coiling.Step S16: in winding process, if detecting, the duration being triggered around wiretap SW2 is more than T1s, or detects and be more than around wiretap SW2 T2s and be not triggered, execute step S17, motor brake error signal, and execute step S18, then the judgement of control unit 6 should Terminate coiling.When terminating coiling, control unit 6 exports corresponding control signal to the stand-by motor to drive the moving head Return to the position of beating the grass of default.When S16 result is no, the stalling of S139 electric machine winding is executed,.

Step S19 is executed, when detecting that switch SW1 of beating the grass is triggered, executes step S110, the control of control unit 6 is driven Dynamic circuit 7 drives main motor 1 to rotate forward at a high speed, and grass-mowing machine enters state of beating the grass, and rope of beating the grass is cut by main motor driving rotation Operation.It beats the grass under state herein, executes step S113, also further whether detection unwrapping wire switch SW3 is triggered.

It beats the grass under state, executes step S114, judge to be put if unwrapping wire switch SW3 is triggered more than T3s Line.At this point, executing step S115, control unit 6 further controls position switching machine while keeping main motor high speed to rotate forward Stand-by motor in structure, stand-by motor are driven the head capsule of grass-mowing machine by gear-rack drive bluff piece, grass-mowing machine are made to go to unwrapping wire Position.At this point, control unit 6 remains driving of the driving circuit 7 to main motor, and head capsule 212 by rack-and-pinion actuation with Spool 211 is detached from, and generates speed difference between 211 acceptor's motor driven of spool and head capsule 212, and rope of beating the grass as a result, is loosened, and is realized Unwrapping wire.At the end of unwrapping wire, step S116 is executed, control unit 6 exports corresponding control signal to the stand-by motor to drive The moving head returns to the position of beating the grass of default.

In above-mentioned rate-determining steps, time interval T1, T2, T3 be used to avoid Operation switch false triggering, avoid opening because of operation It closes false triggering and switches grass-mowing machine mistakenly between winding pattern, unwrapping wire mode, mode of beating the grass.

Under this control method, coiling and beat the grass, unwrapping wire function cannot be realized simultaneously: coiling and beaten if pressed simultaneously Switch grass, motor can be out of service, and system reports an error；If pressing coiling and unwrapping wire switch simultaneously, there is no by switch of beating the grass Words, machine can carry out coiling function, can't realize unwrapping wire function, and any functional conflict will not occur.This is because Unwrapping wire function just can be effective only under the mode beaten the grass at a high speed, is only that will not generate speed by unwrapping wire switch not by switch of beating the grass It is poor and unwrapping wire to spend.

Also, motor can carry out (T2s-T1s) in coiling and stop coiling afterwards, at this time position switching mechanism drive moving head from For winding position back to beating the grass position, the purpose done so has a two o'clock: first, in moving head can coiling limited length, in this way It will not be in excessive line to moving head；Second, revolving speed is very low when brushless motor reversed coiling, using the control for being similar to sine wave Mode processed can further protect motor, prevent from damaging there are shutting down after the coiling time of certain surplus.

Further, after step S111 is performed, switch SW1 of beating the grass unclamps, and executes step S112, motor brake position Switching device control moving head returns to position of beating the grass.

In another embodiment of the present disclosure, the mechanical structure of the grass-mowing machine is similar with a upper embodiment, and difference only exists In referring to Figure 13, the main motor 1 in the present embodiment selects brush motor to realize, and substitutes upper one in fact by wire length detection device Apply automatic control of the Operation switch SW3 realization to unwrapping wire in example.
