And the terminology used herein is for the purpose of illustrating embodiments and is not intended to be limiting of the present invention. The singular forms herein include plural forms unless the context clearly dictates otherwise.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Brief Description of Drawings FIG. 1 is a block diagram of a computer system according to an embodiment of the present invention; FIG. 2 is a block diagram of a computer system according to an embodiment of the present invention; FIG.

Referring to FIG. 1, a golf course lawn care system using a grass cutting machine according to an embodiment of the present invention includes a grass cutting machine 100, a movement inducing line (not shown), a wave separator 200, and a controller 300 Structure can be understood.

The turf cutting machine 100 includes a position tracking unit 110 for receiving a GPS signal and detecting a real time position, a moving unit 120 for moving the turf cutting machine 100, a cutting unit 130 for cutting grass, And a reflector 140 provided on the outer surface.

In this case, it is needless to say that the position tracking unit 110 can use a GPS signal to grasp a real time position, and can use a golf course control system provided by a mobile communication company by paying a predetermined fee.

In addition, the lawnmower 100 includes a photographing unit 150 for photographing the surroundings with a camera provided on at least one surface of the lawnmower 100, and a sensor unit 160 for detecting at least one obstacle present in the surroundings .

Here, the photographing unit 150 photographs the front of the grass cutting machine 100 and transmits the photograph to the controller 300, which will be described later. That is, the manager can check the current state of the lawnmower 100 through the controller 300, and thus can instruct or control the cutting operation according to the situation.

The sensor unit 160 may detect various obstacles by using various sensors such as an ultrasonic sensor, a laser sensor, and an infrared sensor in order to prevent an obstacle from colliding with the grass cutter 100 by sensing an obstacle.

Further, although not particularly shown, it is preferable that a power supply unit that supplies power to the grass cutting machine 100 and a lamp unit that operates at night and emits light are further included.

Next, the movement inducing line (not shown) is separated from the entrance of the cart guide line to the tee box side of the hole, and is guided from the green of the branch guide line and hole leading to the entrance of the grass cutting device 100 to the exit side of the cart guide line, And a lead-inducing line for inducing the departure of the lead wire.

On the other hand, the cart lead wire is a rail rod type in which a rail is laid on the ground and a cart is run on the rail or a magnetic body is buried under the fairway ground surface to form a marker line. And can be installed in a magnetic induction manner for traveling.

The movement guide lines (not shown) are installed in the same manner as the above-described cart guide lines, and are preferably run on the grass cutting machine 100, and are branched from the conventional cart guide lines, The cost of consuming the grass cutting machine 100 for driving the grass cutting machine 100 itself is reduced.

Next, at least one or more ground wave generators 200 are installed in the field so as to irradiate a light wave to the grass cutter 100, to grasp the position of the grass cutter 100 as an optical wave reflected by the reflection unit 140, do.

In this case, the optical wavefront detector 200 observes the distance using a carrier wave between two points to be observed. The phase of a reflected wave reflected after irradiating a light wave such as a visible ray or an infrared ray differs from a phase of the emitted light wave This phase difference can be used to observe the distance as well as the horizontal and vertical tilt.

That is, the distance between the optical wavefront measuring device 200 and the lawnmower 100 is observed using the phase of the reflected wave, and the real-time position and tilt of the lawnmower 100 existing inside the hole And can be confirmed accurately.

It is preferable that the light wavefront detector 200 is installed at the edge of the field in order to accurately grasp the position of the grass cutting machine 100 entering the hole and performing the grass cutting operation.

Finally, the controller 300 controls the operation of the grass cutter 100 according to the position of the grass cutter 100 detected through the position tracking unit 110 and the common rail 200.

Here, the controller 300 may be formed inside the grass cutter 100, and may be installed at a remote place from the field or may be formed as a mobile terminal to facilitate management while the user moves.

As shown in FIG. 2, a golf course lawn care method using a grass cutting machine according to an embodiment of the present invention includes the following steps.

First, in the moving step S10, the grass cutting machine moves to a designated hole along the cart lead wire installed in the field. The hole movement of the grass cutter may be caused by the operation of the manager through the controller or the movement data input by the controller.

Next, in the entry step S20, the grass cutter enters the designated hole along the branched branching line branched from the cart lead.

Next, in the path determination step (S30), the controller determines the movement path of the grass cutter based on the data of the holes inputted.

Specifically, since data related to the terrain of the hole is included in the data of the hole inputted in the above, the route of the grass cutter is determined according to the topography and the course type.

Next, in the cutting step S40, the controller confirms the real-time position of the grass cutter using a position tracker provided in the grass cutter and a light wave locator provided in the field, The grass is cut while moving.

Here, when the grass cutter is required to change directions while it is moving, the controller controls the moving unit to change direction and then move.

Finally, in the step S50, when the grass cutter reaches the green side of the hole during the cutting of the grass, the grass cutter leaves the hole along the joint inducing line.

In addition, in the moving step (S10) to the leaving step (S50), the lawnmower may run by itself while grasping the obstacle to the sensor unit and the photographing unit, or the manager may operate the driving through the controller.

Accordingly, the moving step (S10) to the leaving step (S50) are repeated to perform grass cutting of the entire golf hole.
