2 is a schematic diagram illustrating an apparatus for measuring green information according to embodiments.

Since the manager needs to manage the growth status of the turf on the green located in each golf course, it is necessary to accurately determine the condition of the soil in which the turf is planted. However, in order to measure the condition of the soil planted in the golf course, the manager must directly inspect the large area of the golf course and measure the condition of the soil using a soil property measuring device. Alternatively, it was necessary to indirectly check the condition of the soil inside the golf course by installing a soil property measuring device on the outside of the golf course that does not interfere with the golf game.

In order to solve such a problem, that is, in order to provide an administrator with accurate soil current state information in the golf course, a device capable of detecting the state of the soil at various locations without interfering with the game while being installed directly in the golf course You can think of a way to implement it.

However, since the hole cup is located on the green in the golf course, there is an environmental restriction that it is difficult to supply power at all times. When power is supplied by a battery under such environmental restrictions, if the battery must be frequently replaced in a hall or a device located near the hall, there is a problem that the practicality of the battery is reduced.

In order to solve this problem, that is, to provide information about the condition of the green to the manager and the location of the hole to the golfer, it is possible to think of a way to implement a device that can detect the location at or near the hole. . That is, as shown in FIG. 2 , the hole cutter used by the green keeper to dig a hole eventually excavates the ground of the green and comes into contact with the soil of the green, and indicates the position of the current hole. A green information measuring device 10 capable of detecting may be considered.

Therefore, the function of detecting the GPS position of the green information measuring device 10 needs to be turned on for as long as possible even under power management.

In some embodiments of the present invention, the green information measuring apparatus 10 may further include a charging circuit 170 . For example, when the battery 160 of the green information measuring device 10 is implemented as a rechargeable battery, for example, a secondary battery, the charging circuit 170 may charge the battery 160 .

On the other hand, in some embodiments of the present invention, when the battery 160 of the green information measuring device 10 is implemented as a non-rechargeable battery, for example, a primary battery, the green information measuring device 10 is a charging circuit 170 can be omitted.

The interface unit 180 serves as a passage with various types of external devices connected to the green information measuring device 10 . The interface unit 180 may include at least one of an external charger port, a wired/wireless data port, and a memory card port. In response to the connection of the external device to the interface unit 180 , the green information measuring apparatus 10 may perform appropriate control related to the connected external device.

The controller 190 controls the overall operation of the green information measuring apparatus 10 . The controller 190 may be implemented as a processing circuit such as a microprocessor, a central processing unit (CPU), or an application processor (AP), but the scope of the present invention is not limited thereto. The controller 190 may execute software or a program that implements the function of the green information measuring device 10 .

The controller 190 operates in the power cut-off mode by default, but escapes from the power cut-off mode in response to the wake-up signal, updates the current green information and the hole location, and then enters the power cut-off mode again. When the controller 190 escapes from the power cut mode in response to the wakeup signal and updates the current green information and the hall location, the controller 190 responds to the wakeup signal by the temperature sensor 121, the humidity sensor ( 122), the EC sensor 123, the position acquisition sensor 125, and the wireless communication unit 110 to supply power, and the temperature of the soil from the temperature sensor 121, the humidity sensor 122, and the EC sensor 123, respectively. , humidity, and electrical conductivity, receives GPS location data for the hole from the location acquisition sensor 125, and uses the wireless communication unit 110 to obtain soil temperature, humidity, and electrical conductivity data and GPS location data It may include transmitting to the server 20 . After transmitting the soil temperature, humidity, and electrical conductivity data and GPS location data to the server 20 , the controller 190 may enter a power-off mode.

In this specification, "power cut-off mode" means a state in which power supply to most components of the green information measuring device 10 is cut off. In other words, when the green information measuring device 10 enters the power-off mode, power supply to all components except for the circuit (wake-up signal detection circuit) that must always operate in order to detect the "wake-up signal" is turned off. can be blocked

In some embodiments of the present invention, the “wake-up signal” refers to a signal for escaping the green information measuring device 10 that has entered the power-off mode from the power-off mode.

In some embodiments of the present invention, the wakeup signal may be a signal generated from a sensor input generated by the motion detection sensor 124 . For example, in some embodiments of the present invention, the green information measuring device 10 may include one or more motion detection sensors 124 . While the green keeper digs a hole in a specific position with the hole cutter, for example, when the rotational motion of the hole cutter is detected by the gyro sensor, the green information measuring device 10 detects the current green information and the hole position, and uses the obtained information. It may be transmitted to the server 20 through the network 50 .

In this specification, the "wake-up mode" refers to an operation mode in which the green information measuring device 10 escapes from the power cut-off mode. In the wake-up mode, power supply to all components of the green information measuring device 10 does not need to be guaranteed, and even in the wake-up mode, power supply is provided to only some components as needed, and to some other components. The power supply can be cut off.

In particular, the control unit 190 may control the power supply unit 150 to supply or cut off power to at least one of the control unit 190 itself, the wireless communication unit 110 , and the sensing unit 120 . The control unit 190 may include a wake-up signal detection circuit that should always operate in order to detect the above-described wake-up signal, and when operating in a power-off mode, the control unit 190 excluding the wake-up signal detection circuit itself, wireless Power supply to the communication unit 110 and the sensing unit 120 may be cut off.

The controller 190 may calculate the salinity of the soil using the measured electrical conductivity, humidity, and temperature. Since the electrical conductivity of the soil has a close relationship with the moisture of the soil, the controller 190 corrects the electrical conductivity (EC) measurement value, which is highly dependent on temperature and soil moisture, with respect to temperature and soil moisture, so that more reliable electrical conductivity can be calculated and used to calculate salinity. In addition to this, the controller 190 may mutually correct each of the measured measurement items using related measurement items.

Next, an operation method of the apparatus for measuring green information will be described with reference to FIGS. 8 to 11 .

8 to 11 are flowcharts for explaining a method of operating an apparatus for measuring green information according to embodiments.

Referring to FIG. 10 , the control unit 190 detects a user input through the user input unit 140 ( S100 ). For example, the controller 190 may detect a button signal generated by the green keeper pressing one or more buttons of the green information measuring device 10 as a wake-up signal in order to notify that the position of the hole has been changed. Detection of such a signal may be implemented using, for example, a known interrupt detection method, but the scope of the present invention is not limited thereto.

As a result of the determination, when the user's input is detected (S110, 'Yes'), the control unit 190 controls the power supply unit 150 to supply power to the sensing unit 120 in response to the wakeup signal ( S110).

Specifically, the controller 190 enters the wake-up mode in response to the wake-up signal and starts operation, and then supplies power to the temperature sensor 121 , the humidity sensor 122 , and the EC sensor 123 . . The temperature sensor 121 , the humidity sensor 122 , and the EC sensor 123 may sense soil information such as soil temperature, humidity, and electrical conductivity. At this time, the controller 190 may receive the soil temperature, humidity, and electrical conductivity data from the temperature sensor 121 , the humidity sensor 122 , and the EC sensor 123 .

Also, the controller 190 may supply power to the position acquisition sensor 125 . The location acquisition sensor 125 may sense GPS location data corresponding to the current location. At this time, the controller 190 may receive the current GPS location data from the location acquisition sensor 125 .

The control unit 190 supplies power to the wireless communication unit 110 (S130), and transmits at least one data of soil temperature, humidity, and electrical conductivity data, salinity data, pH data, and GPS location data to the server 20 to (S140). After the transmission, the control unit 190 enters the power cut-off mode again, and the method may proceed to step S100 .

The server 20 may determine whether to update the pre-stored hole location with the received GPS location by comparing the pre-stored hole location with the GPS location received from the green information measuring device 10 . Here, when it is determined that the hole location update is necessary, it may mean a case where the difference between the distance between the pre-stored location data and the GPS location data is equal to or greater than a predetermined distance. For example, it may be determined that the hole location update is necessary only when the distance difference between the stored location data and the GPS location data has a distance difference of several meters or more, such as 1 m or more or 2 m or more. Of course, such a criterion is merely exemplary, and policies and algorithms for determining whether hole location updates are necessary according to specific implementation purposes may be variously changed.

Furthermore, when receiving a plurality of GPS locations from the green information measuring device 10 , the server 20 may select a GPS location determined to be valid data among the plurality of GPS locations. For example, while the green keeper moves a hole located at a first point on the green to a second point, GPS location measurements may be performed at least two times. First, in the case of excavating the second point, if the green keeper rotates the hole cutter left and right for excavation, the gyro sensor detects the rotation motion, and thus GPS measurement can be made. In the case of filling a spot, if the green keeper also rotates the hole cutter left and right to fill the soil, the gyro sensor detects the rotation motion, so that GPS measurement can be made accordingly. According to a predetermined policy and algorithm in consideration of the reception timing of the GPS location data provided from the green information measuring device 10, only the GPS location data firstly received from the green information measuring device 10 is valid, and the second received The used GPS location data may be implemented to determine that it is not valid.

Then, the server 20, the server 20, when the GPS location received from the green information measuring device 10 has a difference over a predetermined range from the pre-stored hole location in the server 20, or green information If it corresponds to the valid GPS location data received from the measuring device 10 and has a difference beyond a predetermined range from the hole location pre-stored in the server 20, the pre-stored hole location is updated to the GPS location, for example, moving Through at least one of the communication device 30 and the golf distance measuring device 40, the updated hole position may be guided to the golfer.

According to this embodiment, the green information measuring device 10 supplies power to the wireless communication unit 110 only when transmitting the measured data to the server 20, and after the server 20 transmission is completed, the wireless communication unit ( 110) while performing power management in a manner that cuts off the power to the sensing unit 120 by supplying power for a sufficient time, the green information measuring device 10 minimizes the power consumption and accurately locates the hole for the golfer can be made available to

However, in some embodiments of the present invention, the power supply policy for the wireless communication unit 110 is not limited to the method described in this embodiment, and if necessary, the power supply method for the wireless communication unit 110 is variously can be changed.

Referring to FIG. 9 , the controller 190 detects a motion detection sensor input ( S200 ). For example, detecting the motion detection sensor input herein may be detecting a sensor signal generated according to the rotational motion of the hole cutter while the green keeper digs a hole. The detection of the sensor signal may be implemented using, for example, a known interrupt detection method, but the scope of the present invention is not limited thereto.

As a result of the determination, when the motion detection sensor input is detected (S210, 'Yes'), the control unit 190 controls the power supply unit 150 to supply power to the position acquisition sensor 125 in response to the wakeup signal. supply (S210). The location acquisition sensor 125 may sense GPS location data corresponding to the current location. At this time, the controller 190 may receive the current GPS location data from the location acquisition sensor 125 .

The controller 190 detects whether the motion detection sensor input has ended (S212). For example, here, detecting that the motion detection sensor input is terminated may include detecting that the input of the sensor signal generated according to the rotational motion of the hole cutter while the green keeper is digging a hole is stopped.

Specifically, when the exercise by the motion sensor is finished, the control unit 190 supplies power to the temperature sensor 121 , the humidity sensor 122 , and the EC sensor 123 ( S220 ). The temperature sensor 121 , the humidity sensor 122 , and the EC sensor 123 may sense soil information such as soil temperature, humidity, and electrical conductivity. At this time, the controller 190 may receive the soil temperature, humidity, and electrical conductivity data from the temperature sensor 121 , the humidity sensor 122 , and the EC sensor 123 .

That is, while the green keeper is excavating the ground with the hole cutter, the measured values by the temperature sensor 121 , the humidity sensor 122 , and the EC sensor 123 may be inaccurate, so the green keeper cuts the ground with the hole cutter. When the excavation is completed, the temperature sensor 121 , the humidity sensor 122 , and the EC sensor 123 may be operated to measure the condition of the soil according to the depth from the ground.

Since step S212 is not essential, the controller 190 may supply power to the temperature sensor 121 , the humidity sensor 122 , and the EC sensor 123 in response to the wake-up signal. In this case, the temperature sensor 121 , the humidity sensor 122 , and the EC sensor 123 may continuously measure the state of the soil.

The control unit 190 supplies power to the wireless communication unit 110 (S230), and transmits at least one data of soil temperature, humidity, and electrical conductivity data, salinity data, pH data, GPS location data, and the server 20 to (S240). After the transmission, the control unit 190 enters the power-off mode again, and the method may proceed to step S200.

Referring to FIG. 10 , the controller 190 drives the position acquisition sensor 125 in the first operation mode ( S300 ). Here, the first operation mode refers to an operation mode of the position acquisition sensor 125 set such that the data update period of the position acquisition sensor 125 is the first period.

The controller 190 determines whether the green information measuring device 10 is located on the green of the golf course by using the GPS location provided by the location acquisition sensor 125 ( S310 ). The controller 190 may determine whether the green information measuring device 10 is located on the green of the golf course by comparing the map information stored in the memory 130 with the GPS location.

When it is determined that the green information measuring device 10 is located on the green of the golf course (S320, 'Yes'), the control unit 190 drives the position acquisition sensor 125 in the second operation mode (S320). . Here, the second operation mode refers to an operation mode of the position acquisition sensor 125 in which the data update period of the position acquisition sensor 125 is set to be a second period shorter than the first period.

While the position acquisition sensor 125 is driven in the second operation mode, the control unit 190 detects a button input or a motion detection sensor input (S330), and additionally, the control unit 190 controls the motion detection sensor by the motion detection sensor Whether or not the input is terminated may be detected ( S332 ).

When a user input is detected, when a motion detection sensor input is detected, or when it is detected whether the motion detection sensor input is terminated after the motion detection sensor input is detected (S340, 'Yes'), the controller 190 controls the temperature sensor ( 121 ), the humidity sensor 122 , and the EC sensor 123 are driven by supplying power (S340), and power is supplied to the wireless communication unit 110 (S350), and soil temperature, humidity, and electrical conductivity Data, salinity data, pH data, GPS location data, and transmits at least one data to the server 20 (S360). Since the detailed content thereof has been described above with reference to FIGS. 8 and 9 , a description of the overlapping content will be omitted.

When it is determined that the green information measuring device 10 is not located on the green of the golf course (S310, 'No'), the method is to drive the position acquisition sensor 125 in the first operation mode (S30) can proceed step by step.

According to the present embodiment, by performing precise power management on the position acquisition sensor 125 , the green information measuring apparatus 10 can provide the golfer with an accurate hole position while further minimizing the power consumption thereof.

Referring to FIG. 11 , the control unit 190 drives the position acquisition sensor 125 ( S400 ). The controller 190 may acquire the current location of the green information measuring apparatus 10 from the location acquisition sensor 125 . Considering the situation in which the green keeper changes the position of the hole on the current green and then moves to the green of another course within a relatively short time to change the position of the hole, the controller 190 controls the The position acquisition sensor 125 may be driven to be turned on all the time or most of the time, but the scope of the present invention is not limited thereto.

For example, it may be determined that the green information and the hole location update are necessary only when the distance difference between the stored location data and the GPS location data has a distance difference of several meters or more, such as 1 m or more or 2 m or more. Of course, these criteria are merely exemplary, and policies and algorithms for determining whether green information and hole location updates are necessary according to specific implementation purposes may be variously changed.

When the pre-stored hall position and the current position match (S420, 'No'), the method may proceed to waiting (S400) for user input and/or motion detection sensor input again.

Here, the case where the pre-stored hole position and the current position match may mean a case where the difference between the stored position data and the GPS position data is less than a predetermined distance. For example, when the distance difference between the stored location data and the GPS location data is less than 1 m, it may be determined that the green information and the hole location update are unnecessary. Of course, such a standard is merely exemplary, and policies and algorithms for determining whether green information and hole location updates are unnecessary may be variously changed according to specific implementation purposes.
