The acquisition unit 101 acquires the position information transmitted from the wireless device 21 provided in each cart 20, stores it in the previous position information table 116, and supplies the position information of the cart 20 to the hole specifying unit 102. The acquisition unit 101 may acquire position information via the base station radio 11.

The hole specifying unit 102 specifies the hole where each cart 20 is located. The hole identification unit 102 can identify the hole where each cart 20 is located by comparing the position information acquired from each cart 20 with the hole area information 117. When the position information of each cart indicates the position in the hole area of one of the holes based on the hole area information 117, the hole specifying unit 102 designates this hole as the current hole (where the cart 20 that transmitted the position information is located) Current area). The hole specifying unit 102 specifies a current hole for a specific cart in the cart 20, for example. The hole specifying unit 102 may specify a cart number 1 for a specific cart 20 and sequentially change the cart 20 to specify a current hole. For example, one cart 20 specified by some method such as a user operation may be used. You may identify the current hall. Hereinafter, when each cart 20 is described, the cart number 1 is specified for the specific cart 20, and when the cart 20 is sequentially changed, for example, one cart 20 specified by some method such as a user operation is included.

The timing when the position information of the cart 20 indicates the position in the hall area for the first time can be estimated as the timing when the cart 20 enters the hall. The timing at which the position information of the cart 20 moves from the inside of the hall area to the outside of the hall area can be estimated as the timing at which the cart 20 exits the hall.

The current hole actual play time calculation unit 103 (current area actual movement time calculation unit) calculates the actual play time (area entrance elapsed time) of the hole containing the cart 20. The current hole actual play calculation unit 103 calculates the current hole actual play time from the time table 110 when entering the hole and the current time. The current hole actual play time calculation unit 103 may refer to the identification result of the hole identification unit 102 and the reception time when the base station radio 11 receives the position information.

The expected play time calculation unit 104 (expected movement time calculation unit) calculates the expected play time (expected movement time) required to play (move) the current hole. The predicted play time calculation unit 104 predicts the next hole from the total of the actual play time up to the previous area calculated by the actual play time calculation unit 109 and the standard play time up to the previous area calculated from the standard play time table 113. Calculate play time. The predicted play time calculation unit 104 calculates the predicted play time at the timing when the hole specifying unit 102 specifies the current hole for the first time, that is, the timing when the cart 20 enters the hole. The predicted play time calculation unit 104 inputs the calculated predicted play time into the predicted play time table 114.

The predicted moving distance calculation unit 105 calculates the moving distance of the cart 20 based on the current hole play time table 111, the standard play time table 113, the predicted play time table 114, and the cart road distance table 115. The predicted moving distance calculation unit 105 calls the predicted play time of the current hole specified by the specifying unit 102 and the distance of the cart road from the predicted play time table 114 and the cart road distance table 115, and the moving distance of the cart 20 Is calculated as the expected travel distance.

The predicted position calculation unit 106 calculates the position of the cart 20 as the predicted position. The predicted position calculation unit 106 calculates the predicted position of the cart 20 using the predicted movement distance calculated by the predicted movement distance calculation unit 105.

The expected movement range calculation unit 107 calculates an expected movement range that is a range in which the cart 20 is expected to move. The predicted movement range calculation 107 calculates the predicted movement range using the calculated predicted position, the previous position information table 116, and the hole area information 117.

The actual play time calculating unit 109 calculates the actual play time up to the previous area that is the area where the cart 20 has passed before the current area specified by the hole specifying unit 20. The actual play time calculation unit 109 refers to the actual play time table 112 and calculates the actual play time up to the previous area by summing up the actual play times of each hole up to the previous area recorded so far.

The position information drawing unit 120 draws the positional relationship between the hall and the cart 20 on the monitor 12 as a map. The position information drawing unit 120 draws the positions of the hall and the cart 20 based on the hole area information 117 and the position information of the cart 20 acquired by the acquisition unit 101. For example, the position information drawing unit 120 draws the position of the cart 20 at the position of the cart 20 acquired by the acquisition unit 101 with an arrow directed in the traveling direction.

The predicted movement range drawing unit 121 draws an image in which the outer periphery of the predicted movement range calculated by the predicted movement range calculation unit 107 is surrounded by a solid line at the corresponding position of the map displayed in the position information drawing unit 120.
The course information table 123 stores the moving order of holes in the course 15 (moving order of a plurality of areas) and the exit of the course 15.

The timer 125 measures the time that has elapsed since the acquisition unit 110 acquired the current position information.

The current time acquisition unit 126 acquires the current time. The current time acquisition unit 126 outputs the acquired current time to the current hole actual play calculation unit 103. The current time acquisition unit 126 outputs the acquired current time to the predicted travel distance calculation unit 105. The current time acquisition unit 126 outputs the acquired current time to the time table 110 that has entered the hall.

The predicted position information storage unit 127 stores the predicted position of the cart 20 calculated by the predicted position calculation unit 106 in the previous position information table 116.

The position correction unit 128 refers to the course 15 information table 123, acquires the position of the exit of the course 15, and corrects the position information or the predicted position of the cart 20 stored in the previous position information table 116.

The previous position information table 116, hole area information 117, and course information table 123 are stored. The storage unit 200 includes, for example, various memories and an HDD (Hard Disk Drive). The storage unit 200 stores various data necessary for processing by the processing unit 100 and various data generated or detected by the processing unit 100. The storage unit 200 performs a storage operation and a read operation by the processing of the processing unit 100. The storage unit 200 is not limited to the one built in the cart management apparatus 10 and may be an external storage device connected by a predetermined interface. As an example of the external storage device, there are a USB memory connected to a USB (Universal Serial Bus) terminal, an external HDD device, a memory card connected by a predetermined memory card slot, and the like.

The time table 110 (area entry time table) when entering the hall is a table that stores the time when each cart 20 entered each hall. As shown in FIG. 6, for example, the time table 110 for entering a hole stores a cart number for identifying each cart 20, a hole number for identifying each hole, and a time for entering the hole in association with each other. The time table 110 when entering the hall stores the current time when the hall identifying unit 102 identifies that the cart 20 has entered the hall as the time when entering the hall.

The current hole play time table 111 is a table in which the current hole actual play time of each cart 20 calculated by the current hole actual play time calculation unit 103 is sequentially associated. In the current hole play time table 111, for example, as shown in FIG. 7, the cart number, the hole number, and the current hole actual play time are associated with each other.

The actual play time table 112 (actual movement time table) shows the hole number of each hole with the current play time of the actual hole when the cart 20 leaves the hole as the actual play time (actual movement time) in the hole of the cart 20. Is a table associated with It can be estimated that the actual play time is the same as the time actually required for the player of each cart 20 to play the predetermined hole. For example, as shown in FIG. 8, the actual play time table 112 is collected for each cart number, and the hole number and the actual play time are associated with each other.

The standard play time table 113 is a table that stores the standard play time of each hole, for example, as shown in FIG. In the standard play time table 113, for example, a prescribed number of hits for each hole is stored. The standard play time is a standard time from when the cart enters the hole until it exits, and is set in advance by an administrator of the golf course 15 or the like. The standard play time table is not set in advance. For example, an average value of play times by a plurality of players may be updated as the standard play time.

The predicted play time table 114 (expected travel time table) is a table in which the predicted play time calculated by the predicted play time calculation unit 104 is associated. As shown in FIG. 9, for example, the predicted play time table 114 is collected for each cart number, and the hole number and the predicted play time are associated with each other.

The cart road distance table 115 is a table in which the distances of the cart roads of the holes 16 are associated with each other as shown in FIG. The distance of the cart road is, for example, the total distance of the cart road on which the cart 20 travels from entering the hall to exiting. The distance of the cart road is set in the cart management apparatus 10 by a manager of the golf course 15 in advance, for example.

The previous position information table 116 is a table that associates the cart number of the cart 20, the position information, the position information storage time, and whether or not the position is calculated based on the prediction, as shown in FIG. 10, for example. The position information of the cart 20 is composed of latitude and longitude. Whether or not the position is calculated based on the prediction is shown in FIG. 10 indicating that the position is the predicted position when the predicted position of the cart 20 is calculated and stored as the position information of the cart 20 by the predicted position calculation process described later. The flag is set as shown by “○”. When the acquisition unit 101 acquires the position information via the base station radio 11, “x” indicates whether or not the position is calculated by prediction in FIG. 10. The position information storage time is the time when the acquisition unit 101 acquires the position information of the cart 20 and stores it in the previous position information table 116, or the predicted position of the cart 20 is calculated by the predicted position calculation process. This is the time stored as position information. The position information storage time is stored in “hour”, “minute”, and “second”.

The hole area information 117 is information indicating an area of an arbitrary size set in advance for each hole. The hall area information 117 may be information defined by latitude and longitude, for example. The hole area information 117 is information used to determine entry / exit into the hall. The hole area information 117 is set around the cart path in the hall, for example, as shown in FIG. The cart 20 moves along the cart path. Therefore, by setting the hole area information 117, when the position information of the cart 20 cannot be acquired, the processing unit 100 can determine that the cart 20 exists in the hole area along the cart path.

FIG. 5 is an image diagram of hole area information 117 set around the cart road. The hole area information 117 is, for example, a map of the hole area that is displayed and the block 150 that surrounds the hole area is set by the administrator of the golf course 15 or the like. I remember it.

The operation performed by the processing unit 100 from when the cart 20 enters the course 15 until it exits is a process as shown in FIG. The operation of the processing unit 100 shown in FIG. 11 is executed at a predetermined timing. When the predetermined timing is reached, the processing unit 100 starts the timer 125 (step S201), and determines whether or not the acquisition unit 101 has acquired the position information before the timer 125 times out (step S202). The processing unit 100 determines that the timer 125 has timed out when the predetermined time is counted by the timer 125 in step 202, for example.

When the position information cannot be acquired before the timer 125 times out (step S202: No), the processing unit 100 determines whether the cart 20 is in the hall from the previously acquired position information of the cart 20 in the specifying unit 102. Whether or not is estimated (step S203). For example, the processing unit 100 compares the previous position information table 116 with the hole area information 117 in the specifying unit 102 and enters the hole when the latitude and longitude of the cart 20 whose position is to be calculated is within the hole area. Estimated. When it is estimated that the cart 20 is not in the hall (step S203: No), the processing unit 100 returns to step S202 and determines again whether the position information has been acquired before the timer 125 times out.

When the processing unit 100 estimates that the cart 20 is in the hall (step S203: Yes), the predicted movement range calculation unit 107 calculates a range where the cart 20 is expected to exist as the predicted movement range, The predicted movement range drawing unit 121 draws the predicted movement range (step S204). Details of the “expected movement range calculation / drawing process” performed by the processing unit 100 in step S204 are, for example, processes as shown in FIG.

When the position information can be acquired before the timer 125 times out (step S202: Yes), the processing unit 100 determines whether or not the cart 20 has newly entered the hole this time (step S207).

When the cart 20 newly enters the hole this time (step S207: Yes), the processing unit 100 performs processing when entering the hole (step S209). Details of the “processing when entering the hole” performed by the processing unit 100 in step S209 are, for example, processing as shown in FIG.
After performing the “processing when entering the hall”, the processing unit 100 draws the position of the cart 20 superimposed on the image of the hole using the position information acquired by the acquisition unit 101 (step S211).

When the cart 20 has not newly entered the hole this time (step S207: No), the processing unit 100 determines whether or not the cart 20 has left the hole this time (step S208). When the processing unit 100 leaves the hole this time (step S208: Yes), the processing unit 100 performs “processing when exiting the hole” (step S210). Details of the “processing when exiting the hole” performed by the processing unit 100 in step S210 are, for example, processing as shown in FIG. The processing unit 100 performs “processing when exiting the hall” and then draws the position of the cart 20 on the hole image based on the hole area information 117 and the position information of the cart 20 acquired by the acquisition unit 101. (Step S211). That is, the processing unit 100 draws the position of the cart 20 in the hall.

After the drawing process in step S211 or the predicted movement range calculation / drawing process in step S204, the processing unit 100 determines whether or not the current location of the cart 20 is within the course 15 (step S206). If the processing unit 100 determines that the current location of the cart 20 is within the course 15 (step S206: Yes), the processing unit 100 returns to step S202 and determines again whether the position information has been acquired before the timer 125 times out. When the processing unit 100 determines that the current location of the cart 20 is not within the course 15 (step S206: No), the processing ends.

The processing of steps S201 to S203 and steps S207 and S208 may be executed by the specifying unit 102, for example. For example, the expected movement range calculation unit 107 may execute the process of step S204. For example, the position information drawing unit 120 may execute the process of step S211. The process of step S205 may be executed by the predicted movement range drawing unit 121, for example.

The “processing when entering the hall” performed by the processing unit 100 in step S209 will be described with reference to FIG. When the processing of step S209 is started (that is, when the cart 20 newly enters the hall this time), the processing unit 100 causes the specifying unit 102 to store the time when the cart 20 enters the hall in the time table 110 when entering the hall. Store (step S301).

Next, the processing unit 100 determines in the specifying unit 102 whether the hole containing the cart 20 is the first hole in the course 15 (step S302). The processing unit 100 determines whether or not the hole number of the hole containing the cart 20 is 1 by referring to the hole area information 117 and the course 15 information table 123 in the determination unit 102 in the determination unit 102, for example. The cart 20 normally enters the hall number 1 from the hole. Therefore, when the hole number containing the cart 20 is 1, the specifying unit 102 of the processing unit 100 determines that the hole containing the cart 20 is the first hole in the course 15. The number of halls in which the cart 20 enters is usually 1 but can be changed arbitrarily.

When it is determined that the hole containing the cart 20 is not the first hole in the course 15 (step S302: No), the processing unit 100 uses the actual play time calculation unit 109 to determine the previous hole that has passed so far. The actual play time (actual movement time) is calculated (step S303). In the actual play time calculation unit 109, the processing unit 100 calculates the actual play time up to the previous hole by adding up the actual play time of each hole up to the previous hole. The processing unit 100 calculates the actual play time up to the previous hole by reading the actual play time of each hole up to the previous hole from the actual play time table 112 in the actual play time calculation unit 109 and summing them up.

Next, the processing unit 100 calculates the predicted play time of the current hole (expected travel time required to move the current area) in the predicted play time calculation unit 104 (step S304). The processing unit 100 uses the predicted play time calculation unit 104 to calculate the predicted play time in step S303, the standard play time of the current hole (standard movement time), the standard play time of the previous hole that has passed so far, and step S303. The actual play time (actual movement time) to the previous hole is calculated.

The processing unit 100 uses the predicted play time calculation unit 104 to calculate the predicted play time using, for example, the following equation (1). In equation (1), T _E = (expected play time), T _S = (standard play time), T _R = (actual play time), n = (current hole number).

That is, the processing unit 100 expected play time calculation unit 104, the expected play time T _E of the hole number n, the standard playing time T _S of the Hall n, from the Hall number 1 is a hole passing through before the current hall n calculated by multiplying the total proportion of the real-play time T _R to the sum of the standard playing time T _S for each hole to hole number n-1. Processing unit 100 in the expected play time calculation unit 104, a standard playing time _{T S} of each hole, reads from the standard time table 113.

When it is determined that the hole containing the cart 20 is the first hole in the course 15 (step S302: Yes), the processing unit 100 causes the predicted play time calculation unit 104 to set the predicted play time to the standard play time of the current hole. (Step S306). The predicted play time calculation unit 104 calculates the expected play time using the actual play time and the predicted play time of all the holes passed before the current hole, not the actual play time of the previous hole alone. It is possible to calculate an accurate predicted play time according to 20. Then, when the current hole is the first hole, the predicted play time calculation unit 104 calculates the standard play time of the current hole as the predicted play time because there is no hole that has passed before the current hole, step S304, After calculating the predicted play time in step S306, the processing unit 100 stores the calculated predicted play time in the predicted play time calculation unit 104 in association with the cart number of the cart 20 and the hole number of the current hole in the predicted play time table 114. (Step S305), and the “processing when entering the hall” is terminated.

The “processing when exiting the hole” performed by the processing unit 100 in step S210 will be described with reference to FIG.

When the processing of step S210 is started (that is, when the cart 20 has newly exited the hole this time), the processing unit 100 determines whether the hole from which the cart 20 has exited is the last hole in the course 15 in the specifying unit 102. Is determined (step S401). In step S401, the processing unit 100 uses the identifying unit 102 to determine that the hole number identified using the hole area information 117 before determining that the hole has been exited is the same as the hole number of the last hole set in advance. Determine if there is. In step S401, the processing unit 100 refers to the standard play time table 113 or the cart road distance table 115 and stores the hole number specified using the hole area information 117 before determining that the hole has left the specifying unit 102. It may be determined whether the number is the same as the largest hole number.

When the hole where the cart 20 comes out is not the last hole in the course 15 (step S401: No), the processing unit 100 calculates the actual play time which is the actual play time within the hole of the hole where the cart 20 comes out. Then, it is written in the actual play time table 112 (step S402), and the “processing when exiting the hole” is terminated. In the process of step S402, the processing unit 100 calculates the current hole actual play time at the current hole actual play time calculation unit 103, and the actual play time at the timing when the cart 20 leaves the hole is actually played. It may be stored in the time table 112.
When the hole from which the cart 20 has come is the last hole in the course 15 (step S401: Yes), the “processing when leaving the hole” is ended.

The “expected movement range calculation / drawing process” performed by the processing unit 100 in step S204 will be described with reference to FIG.

When the processing of step S210 is started (that is, when the cart 20 is in the hall), the processing unit 100 is identified by the current hall play time calculation unit 103 that the cart 20 is in step S203. The actual play time of the current hole is calculated (step S501). The current hole play time calculation unit 103 calculates the time elapsed since the cart 20 entered as the actual play time of the current hole (step S501). Next, in the specifying unit 102, the processing unit 100 determines whether the actual play time of the current hole calculated by the current hole play time calculation unit 103 exceeds the expected play time of the current hole (step S502).

When it is determined that the actual play time of the current hole does not exceed the expected play time of the current hole (step S502: No), the processing unit 100 confirms the previous position information recording time in the predicted movement distance calculation unit 105. (Step S503). In step S503, the predicted movement distance calculation unit 195 refers to the previous position information table 116 and confirms the previous position information recording time. Next, the processing unit 100 uses the predicted travel distance calculation unit 105 to calculate the travel distance of the cart 20 from the previous position information recording time confirmed in step S503 as the predicted travel distance (step S504). In step S504, the predicted moving distance calculation unit 105 calculates the predicted moving distance of the cart 20 using the previous position information recording time, the distance of the cart path of the current hole, and the predicted play time of the current hole confirmed in step S503. To do. FIG. 15B and FIG. 16B are diagrams illustrating the result of the processing unit 100 calculating the expected travel distance of the cart 20 as will be described later.

The processing unit 100 calculates the predicted moving distance of the cart 20 from the previous position information recording time in the predicted moving distance calculation unit 105 using, for example, the following equation (2). In equation (2), D _M = (expected travel distance), D _C = (current cart distance of the hall), T _E = (expected play time), ΔT = (elapsed time from previous position information recording time) ).

That is, the processing unit 100 predicted moving distance calculating unit 105, of the cart 20 now the distance D _C cart road holes divided by the expected play time T _E of the current hall of the cart 20, from the position information of the previous The expected moving distance _DM is calculated by multiplying the elapsed time ΔT from the recording time.

In the processing unit 100 is expected movement distance calculating unit 105 acquires the current distance D _C cart path hole of the cart 20 from the distance table 115 of the cart path. In the processing unit 100 is expected movement distance calculating unit 105 obtains the expected play time _{T E} of the current hall of the cart 20 from the expected play time table 114. That is, the expected play time T _E the expected moving distance calculating unit 105 acquires the (step S304 in FIG. 12) the cart 20 is calculated when entering the current hole, the expected play time of the current hole. The processing unit 100 causes the estimated travel distance calculation unit 105 to subtract the previous position information recording time from the current time acquired by the current time acquisition unit 126 by subtracting the elapsed time ΔT from the recording time from the previous position information. The expected travel distance is calculated.

After calculating the predicted moving distance, the processing unit 100 calculates the position of the cart 20 as the predicted position using the predicted moving distance in the predicted position calculating unit 106 (step S505). FIG. 15C and FIG. 16C are views illustrating the processing unit 100 calculating the predicted position of the cart 20 as will be described later. For example, there are the following two methods for calculating the predicted position of the predicted position calculation unit 106.

It can be estimated that the cart 20 exists somewhere on the circumference of a circle centered on the position indicated by the previous position information and having the expected moving distance as a radius. As a first predicted position calculation method, the predicted position calculation unit 106 has a circle centered on the position indicated by the previous position information and the expected moving distance as a radius, and the position indicated by the previous position information in the traveling direction. The position where the extended straight line intersects is calculated as the expected position of the cart 20. The predicted position calculation unit 106 can estimate the traveling direction of the cart 20 by using the previous position information and the previous position information. Further, the predicted position calculation unit 106 can acquire and use the traveling direction included in the GPS data at the same time when the acquisition unit 102 acquires the position information.

In the first predicted position calculation method, when the calculated predicted position of the cart 20 is outside the hole, the predicted position calculation unit 106 may correct the traveling direction until the predicted position of the cart 20 is in the hole. Good. For example, the predicted position calculation unit 106 first shifts the traveling direction to the left by 15 degrees, and determines whether the corrected predicted position of the cart 20 is in the hole. If the predicted position is not in the hole, the predicted position calculation unit 106 shifts the traveling direction to the right by 15 degrees to determine whether the predicted position is in the hole. If it is still not in the hole, the predicted position calculation unit 106 shifts the traveling direction to the left by 30 degrees and determines whether or not the predicted position is in the hole. If it is still not in the hole, the predicted position calculation unit 106 determines whether the predicted position in which the traveling direction is shifted to the right by 30 degrees is in the hole. When the predicted position that has been corrected repeatedly in this way is in the hole, the predicted position calculation unit 106 calculates the corrected predicted position as the predicted position of the cart 20.

As a second predicted position calculation method, position information on the cart path of the cart 20 is set in advance by a user or the like and stored in the hall area information 117. The predicted position calculation unit 106 searches for the cart path that is closest to the position indicated by the previous position information, and calculates the position that has been advanced by the expected movement distance on the cart path as the predicted position of the cart 20.

After calculating the predicted position of the cart 20, the processing unit 100 determines in the predicted position calculation unit 106 whether the predicted position of the cart 20 is out of the hole (step S506). In the first predicted position calculation method, after the above four corrections are repeated, if the predicted position is not in the hole, the predicted position calculation unit 106 determines that the predicted position is outside the hole.

When the predicted position of the cart 20 is outside the hole (step S506: Yes), the processing unit 100 performs an “outside hole discharge process” shown in FIG. 17 described later (step S510). When it is determined that the predicted position of the cart 20 is in the hall (step S506: No), the processing unit 100 causes the predicted movement range calculation unit 107 to calculate the predicted movement range of the cart 20 (step S507). The predicted movement range calculation unit 107 calculates a range including the previous position information of the cart 20 to the predicted position of the cart 20 calculated in step S505 as the predicted movement range. The expected movement range calculation unit 107 manages the position information of the hole as a plurality of blocks, and for example, as illustrated in FIG. 15D, the previous position information, the predicted position, and a straight line connecting the two points. The included block is calculated as the expected movement range. As another method, the predicted movement range calculation unit 107 can also calculate the inside of a circle whose diameter is a line segment connecting the previous position information and the predicted position as the predicted movement range.

When the predicted movement range of the cart 20 is calculated, the processing unit 100 draws the predicted movement range in the predicted movement range drawing unit 121 (step S508). The predicted movement range drawing unit 121 draws a frame surrounding the outer periphery of the predicted movement range, for example, as shown in FIG. After drawing the expected movement range or executing the “outside hole discharge process”, the processing unit 100 updates the previous position information table 116 (step S509), and the “expected movement range calculation / drawing process”. Exit. In the process of step S509, the processing unit 100 updates the previous position information of the cart 20 to the predicted position calculated in step S505 and sets the predicted position flag to ◯. Note that the process in step S509 can be performed any time after the process in step S505 is completed. For example, the process in step S509 may be executed before step S506.

FIG. 16A illustrates a display screen displayed on the monitor 12 by the position information drawing unit 120 and the expected movement range drawing unit 121. The position information drawing unit 120 draws the position of the cart 20 with a black circle in association with the hole area based on the hole area information 117 and the previous position information table 116. The position information drawing unit 120 draws the position of the cart 20 with a black circle instead of an arrow based on the predicted position flag set in the previous position information table 116. The predicted movement range drawing unit 121 draws a frame surrounding the outer periphery of the predicted movement range calculated in step S507.

The “outside hole discharge process” performed by the processing unit 100 in step S510 of FIG. 14 will be described with reference to FIG.

When the process of step S510 is started (that is, when the predicted position is outside the hole), the processing unit 100 starts the “outside hole discharge process”, and the specifying unit 102 determines that the current hole is the last hole of the course 15. It is determined whether or not (step S601). The processing unit 100 determines whether or not the hole number of the hole containing the cart 20 is 9 with reference to, for example, the hole area information 117 and the course information table 123 in the determination of the step S302 in the specifying unit 102. In the cart 20, the hole with the hole number 9 is usually the last hole in the course 15. Therefore, when the hole number containing the cart 20 is 9, the specifying unit 102 of the processing unit 100 determines that the hole containing the cart 20 is the last hole in the course 15. The number of holes for the cart 20 is usually from 9, but it can be changed arbitrarily. When it is determined that the current hole is the last hole of the course 15 (step S601: Yes), the processing unit 100 determines the current position of the cart 20 as the exit of the course 15 in the position correction unit 128 (step S603). ), “Out-hole discharge process” is completed. The position correction unit 128 refers to the course information table 123, acquires the position of the exit of the course 15, and corrects the position information or the predicted position of the cart 20 stored in the previous position information table 116. When it is determined that the current hole is not the last hole of the course 15 (step S601: No), the processing unit 100 determines the current position of the cart 20 as the entrance of the next hole in the position correction unit 128 (step S601). S602), “out-hole discharge processing” is terminated. The position correction unit 128 refers to the course information table 123, acquires the position of the entrance of the next hole of the course 15, and corrects the position information or the predicted position of the cart 20.

As described above, in the embodiment described above, the predicted movement range is calculated not only by calculating the position of the cart 20 based only on the position information acquired from the GPS but also by considering the cart road, the standard play time, and the previous play time. As a result, the cart 20 can be managed more accurately. In addition, since a gyro and a vehicle speed signal are not used, setup to a golf cart is easy. Thereby, the golf course manager can manage the position information non-positioned golf cart by a simple setup, and can quickly and appropriately respond to the emergency situation of the player. In addition, when the movement distance is calculated using the speed data added to the GPS, the error increases when the movement and the stop are repeated like a golf cart, but the cart road, the standard play time, By calculating the expected movement range in consideration of the play time so far, the cart 20 can be managed more accurately. In particular, when a golf cart becomes unable to acquire position information, by predicting the existence range considering not only the previous position information but also the standard play time of the hole, the distance of the cart path, the skill of the player, It becomes possible to predict the position of the golf cart more accurately.

Although the example of the cart 20 that moves in the golf course as a moving body has been described in the above examples, the present embodiment can be applied as long as it moves in the area other than the cart.
