Hole position update apparatus, hole position update system and hole cutter

A hole cutter comprising:

• an excavator for excavating ground;
• a GPS circuit for detecting a GPS position;
• a mobile communication circuit for providing access to a server through a mobile communication network;
• and
• the mobile communication circuit includes a control circuit for transmitting the GPS position to the server in response to a wakeup signal generated by at least one button or sensor,
• wherein the control circuit compares map information including position information on a golf course and the GPS position, and determines whether the hole cutter is disposed in a green of the golf course, and
• wherein the control circuit sets a data update period of the GPS circuit to be a first period when the hole cutter is not disposed in the green of the golf course, and sets the data update period of the GPS circuit to be a second period that is different from the first period when the hole cutter is disposed in the green of the golf course.

A hole location updating system comprising:

• a hole location updating device;
• and
• a server,
• wherein the hole location updating device includes
• a hole cutter combiner for providing a combination to a hole cutter,
• a GPS circuit for detecting a global positioning system (GPS) position on the hole location updating device,
• a mobile communication circuit for providing access to the server through a mobile communication network, and
• a control circuit for transmitting the GPS position to the server by use of the mobile communication circuit in response to a wakeup signal, and
• the server compares a stored hole location and the GPS position received from the hole location updating device and determines whether to update the stored hole location with the GPS position,
• wherein the control circuit compares map information including position information on a golf course and the GPS position, and determines whether the hole location updating device is disposed in a green of the golf course, and
• wherein the control circuit sets a data update period of the GPS circuit to be a first period when the hole location updating device is not disposed in the green of the golf course, and sets the data update period of the GPS circuit to be a second period that is different from the first period when the hole location updating device is disposed in the green of the golf course.

A hole location updating device including a hole cutter combiner providing a combination to a hole cutter, comprising:

• a GPS circuit for detecting a GPS position on the hole location updating device;
• a mobile communication circuit for providing access to a server through a mobile communication network;
• and
• a control circuit for comparing a stored hole location and the GPS position detected by the GPS circuit to determine whether a hole location update is needed in response to a wakeup signal, and transmitting the GPS position to a server when the hole location update is determined to be needed,
• wherein the control circuit compares map information including position information on a golf course and the GPS position to determine whether the hole location updating device is disposed in a green of the golf course, and
• wherein the control circuit sets a data update period of the GPS circuit to be a first period when the hole location updating device is not disposed in the green of the golf course, and sets the data update period of the GPS circuit to be a second period that is different from the first period when the hole location updating device is disposed in the green of the golf course.
