DESCRIPTION OF THE PREFERRED EMBODIMENTS Golf cart operation management device of the present invention
A first embodiment in which a weak radio wave is first used in the device will be described with reference to FIG. Although the layout of the golf course is shown in this figure, the number of holes is shown as five for convenience of explanation. However, the present invention is not limited to five holes, but may be nine holes, eighteen holes, or more holes. As shown in this figure, the administration building and the plurality of repeaters R1 to R18 are one.
The second, third, fourth, and fifth holes are provided around the respective holes so as to surround the respective holes. This management building and multiple repeaters R1
R18 to R18 are provided with a transceiver for transmitting and receiving a weak radio wave, respectively. The management building → repeater R1 → repeater R2
→ Repeater R3 → Repeater R4 .... → Repeater R1
A loop-shaped wireless communication network is configured so that information can be transmitted in the order of 7 → repeater R18 → management building.

That is, each of the repeaters R1 to R
18 is wirelessly connected in a relay manner to transfer information, during which the repeaters R1 to R18 receive information from the golf cart acquired, generate information to be transferred based on the received information, and The receiver of the management building receives the position information and the like of the golf cart. This allows the management building to grasp the current position of the golf cart playing in each hole. In this wireless communication network, information is packetized and transmitted.
First, the management building packetizes information to be transmitted to the player playing in each hall in a predetermined format, attaches the identification code ID1 of the repeater R1 to the packet header, and transmits the packet from the weak radio wave transmitter of the management building. . In this case, the player is specified by specifying the golf cart carrying the golf bag of the player.

The management building and the repeaters R1 to R18
Has a unique identification code ID that does not overlap
0 to ID18, and the management building has a recognition code I
D0 is assigned, and the management building transmits the packet from the transmitter of the weak radio wave by attaching the identification code ID1 assigned to the repeater R1 to which information is to be transmitted to the packet header.
The service range of the weak radio wave transmitted from the management building is limited, but the repeater R1 is arranged within the service range.

The packet having the identification code ID1 of the repeater R1 in the packet header transmitted as a weak radio wave is the identification code ID of the repeater R that has received the packet.
Only the repeater R1 to which 1 is assigned receives the received packet. The repeater R1 decodes the received packet and outputs the golf carts K1 to K5.
If there is information to be transmitted to golf carts K1-K
5 so as to transmit information to each golf cart K1 to K5.
IDK1 that is uniquely assigned to each
To IDK5, and the information is transmitted from the transmitter / receiver of the weak radio wave.

In order to confirm the current position of each of the golf carts K1 to K5, the repeater R1 is operated by the golf cart K1.
To K5. This information transmission request is transmitted to the repeater R of the golf carts K1 to K5.
Only the golf cart K located in the service range of No. 1 receives the information, and any one of the golf carts K that has received the information transmission request has its own identification code IDK1 to notify the management building of its current location. The information to which any one of IDK5 is added is transmitted from the mounted weak radio wave transmitter. When the repeater R having received the information determines that the golf cart K which has sent the current position is closest to the repeater R, a comparison processing result of this information and the electric field strength of the received signal is transmitted from the management building. The packet is added to the packet and transmitted to the next repeater R.

Further, the information transmitted from the repeater R to the golf cart K is received, and the information is transmitted to the golf cart K.
If the DK is attached, the information is decoded and the information content is displayed on the equipped display. The player receives the information from the management building by looking at the contents displayed on the display. Note that the golf carts K1 to K5 move through the holes as they play, and the reply of the current position information transmitted from the golf carts K1 to K5 is transmitted by weak radio waves. Only the repeater R can receive a reply from the golf carts K1 to K5. In addition, a plurality of repeaters R may receive this reply. In this case, the repeater R that receives the reply is determined by the magnitude of the electric field strength as described later. This is for determining the current position of the returned golf carts K1 to K5 as the installation position of the received repeater R.

Here, the repeater R1 is a golf cart K1.
If no reply is received from any of ~ K5
The packet transmitted from the management building is transmitted from a built-in weak radio wave transmitter with the identification code ID2 of the repeater R2 added to the packet header. As described above, the repeater R2 receives and takes in the packet in which the identification code ID2 of the repeater R2 transmitted by the weak radio wave is added to the packet header. Then, the same processing as that of the repeater R1 is performed, the identification code ID3 of the repeater R3 is reattached to the packet header, and transmitted from the transmitter of the weak radio wave built in the repeater R2.

The packet transmitted from the repeater R2 is received and captured by the repeater R3, and the same processing as described above is performed. However, the repeater R3 is arranged around the fourth hole. Since the golf cart K1 is moving in the fourth hole and is within the service range, the golf cart K1 receives the information transmitted from the management building by the repeater R3. If this information is transmitted to the golf cart K1 with the identification code IDK1 of the golf cart K1, information from the management building is displayed on the display of the golf cart K1. Also, an information transmission / transmission request is made from the repeater R3 to the golf cart K1, and the golf cart K1 transmits the reply from the mounted weak radio wave transmitter. When the repeater R3 recognizes the radio wave from the golf cart K1, the repeater R3 adds the position information of the golf cart K1 to the packet transmitted between the repeaters, and further adds the information of the electric field strength of the received radio wave. Is sent.

Similarly, an information transmission request is again made from the repeater R4 to the golf cart K1, and the repeater R4
Performs the same processing as the repeater R3. Where repeater R
The position information of the golf cart and the electric field intensity information of the radio wave are already added to the packet received from the packet No. 3. The repeater R4 compares this electric field intensity information with the electric field intensity information received by itself. When the own strength is high, the packet rewrites the position information and the electric field strength information in the packet and transmits the packet to the repeater R5. At this time, it goes without saying that the identification code ID5 of the repeater R5 is added to the packet header. The information indicating the current position of the golf cart K1 is obtained by adding the identification code ID4 of the repeater R4 to the transmission information from the golf cart K1. This is because the position of the repeater R is fixed in advance, and the current position of the golf cart K can be known by specifying the repeater R. In this way, the packet transmitted from the management building is transmitted in a relay manner to each of the repeaters R1 to R18, during which the current position information of the golf carts K1 to K5 acquired by each of the repeaters R1 to R18 is added to the packet. Will be.

In the case shown, the repeater R10 shows the current position information of the golf cart K3 playing in the fifth hole, the repeater R12 shows the current position information of the golf cart K2 playing in the third hole, and the repeater R14. The current position information of the golf cart K4 playing in the second hole, the golf cart K playing in the first hole by the repeater R18.
5 current position information, each repeater R10, R1
2, R14 and R18 add this information to the packet and transfer the packet to the next repeater R. This allows
The management building that has received the packet from the repeater R18 can know the current positions of all playing golf carts K1 to K5 by decoding the packet, and can manage the operation of the golf carts K1 to K5.

The management building and each of the repeaters R1 to R1
8 returns an ACK indicating that the packet has been normally received to the management building or any of the repeaters R1 to R18 when the packet intended for itself is normally received. If the packet could not be received normally, an NCK indicating that the packet could not be normally received is returned to the transmitting management building or each of the repeaters R1 to R18. As a result, the reliability of the looped wireless communication network is improved.

Next, FIG. 2 is a block diagram showing a schematic configuration of the transceiver 1 built in each repeater R. In this figure, the control processing circuit 3 receives a packet with its own identification code ID as described above, creates an ACK signal when the packet is normally received, and generates an NCK signal when the packet is not normally received. When a signal is created, and next there is information to be transmitted to the golf cart in the packet, transmission information for the information is created and an information transmission request signal for requesting the golf cart is created. Next, a packet to be transmitted to the next repeater R is created. Further, the wireless transceiver 2 receives the packet transmitted from the management building or another repeater R, and receives a reply to the information transmission request signal transmitted from the golf cart K and sends it to the control processing circuit 3. Then, it receives various signals from the control processing circuit 3 and transmits a weak radio wave via the antenna 5.

Since the transmission power of the repeater R is small, the power supply 4 using local energy can be used. For example, this power supply can be a solar cell. Next, FIG. 3 is a block diagram showing a schematic configuration of the transceiver 10 mounted on the golf cart K. In this figure, the control processing circuit 13 receives and decodes the information provided with its own identification code IDK as described above, and displays the information content on the input / output device 14 such as an input / display device. When the information transmission request signal is received from the repeater R,
When a reply signal is created and information to be transmitted to the management building is input from the input / output device 14, a signal corresponding to the information is created. The wireless transceiver 12 receives the information transmitted from the repeater R and sends it to the control processing circuit 13. Then, upon receiving various signals from the control processing circuit 13,
A weak radio wave is transmitted via the antenna 11.

The power source of the transceiver 10 is as follows.
Generally, since the golf cart K is loaded with a cart power source 15 such as a battery for causing the golf cart K to run on its own, the cart power source 15 is used.

Next, FIG. 4 schematically shows a loop-shaped wireless communication network using weak radio waves described in the description of FIG. In this figure, the management building 21 and the repeater R1
(22) to the repeater R4 (25) form a loop-shaped wireless communication network. That is, management ridge 21 → repeater R1 → repeater R2 → repeater R3 → repeater R4 →
A wireless communication network is configured by being connected wirelessly in the order of the management building 21. However, in this case, the number of repeaters is four.

The golf cart 26 is located near the repeater R1, and an information transmission transmission request is transmitted from the repeater R1 to the golf cart 26, and information is transmitted to the repeater R1 as a reply. Also, repeater R
The golf cart 27 is located in the vicinity of No. 3, and an information transmission transmission request is transmitted from the repeater R3 to the golf cart 27, and information is transmitted from the golf cart 27 to the repeater R3 in response to the request. These golf carts 2
The information transmitted from each of the golf carts 6 and 27 is transmitted to the management building 21 through a loop-shaped wireless communication network, and the management building 21 transmits the current position of each golf cart and information from each golf cart or information to each golf cart. Can be managed. It should be noted that the exchange of information between the management building 21 and the repeaters 22 to 25 is performed by packets as described above.

Next, FIG. 5 schematically shows a case where an information transmission signal in response to an information transmission transmission request transmitted from a golf cart is received by a plurality of repeaters. This drawing shows a case where the golf cart 26 transmits information in response to an information transmission request from the repeater R1, and this information transmission signal is received by the repeaters R1, R2, and R3. In this case, the repeater R
It is assumed that the reception electric field strength of the repeater R2 is medium, and the reception electric field strength of the repeater R3 is low. In general, it is assumed that the stronger the received electric field intensity is, the closer the position is. Therefore, in this case, it is determined that the golf cart 26 is located closest to the repeater R1 (22), and the repeater R1 receives the information transmission signal. I do.

More specifically, only the repeater R1 that has made an information transmission request to the golf cart 26
6 receives the response signal transmitted from the receiver 6 and recognizes the radio wave, adds the position information of the golf cart to the packet transmitted between the repeaters, and further adds the electric field strength information of the received radio wave to the packet. Is sent. Then, the next repeater R2 receiving the packet similarly issues an information transmission request to the golf cart 26, and performs the same processing as the previous repeater R1. Where the previous repeater R
The golf cart 26 already exists in the packet received from
The repeater R2 compares the information on the electric field strength with the information on the electric field strength received by the repeater R2. Is rewritten, and the packet is transmitted to the next repeater R3. In the case shown in the figure, the above processing is not performed because the electric field intensity of the repeater R1 is higher, and the data of the packet is transferred to the next repeater as it is.

Another device is a golf cart 2.
6 to receive radio waves from multiple repeaters,
The received electric field strength information may be held, and the comparison process may be performed when a packet is transferred between repeaters. In addition, as the current position information of the golf cart,
In the case of the repeater R1, the recognition code I of the golf cart 26
By adding the identification code ID of the repeater R1 to the DK, the current position information of the golf cart 26 is created, and the packet is transmitted to the next repeater R2.

FIG. 6 shows an example of the format of a packet for transferring information between the management building and the repeater.
As shown in this figure, the packet is composed of three areas, the first area D1 is a preamble area composed of dummy bits for synchronizing pits and characters, and the second area D2 is a golf cart to be described later. The third area D3 is an error detection code (CRC) area for detecting an error in data, which is a data area including information to be transmitted, current position information of the golf cart, and the like.

FIG. 7 shows an example of a detailed format of the data area which is the second area D2. As shown in this figure, the data area consists of five areas, and the first area D1 is the ID of the repeater to be received.
The second area D2 is a status data area including control flags and the like required in the communication network, and the third area D3
Is a data area transmitted from the management building to the golf cart, and it is natural that the data can be transmitted individually to the golf cart, but the data can be broadcast to all golf carts. The fourth area D4 is an area in which data received from the golf cart and sent to the management building while the packet is being relayed by the repeater is incorporated. The fifth area D5 is a data area in which the position information from the cart and the received electric field intensity information are sent to the management and the like. When transferred between repeaters, the electric field intensity received by each repeater is compared, and This data is updated as information.

In the above-described golf cart operation management device of the present invention, the service area is as small as several tens of meters because the repeater transmits weak radio waves. Therefore, it was necessary to provide many repeaters. Then, another different communication system form of the golf cart operation management device of the present invention which can reduce the number of repeaters will be described with reference to FIG. In this golf cart operation management device,
Instead of a repeater having a weak radio wave transmitting / receiving device, the repeater is provided with a specific low power transmitting / receiving device having a weak radio wave receiving unit. Specified low power radio wave service
The service area is several hundred meters.

FIG. 8 shows the layout of a golf course, but the number of holes is shown as five for convenience of explanation. However, the present invention is not limited to 5 holes, but 9 holes.
Holes, 18 holes, or more. As shown in this figure, the administration building and a plurality of repeaters R1 to R11 are located near the teeing ground and green of the first, second, third, fourth, and fifth holes. It is arranged. However, in the case of a long hole such as the fourth hole, it may be provided in the middle of the fairway. Further, when the green and the teeing ground of the next hole are close to each other, it is not necessary to dispose the tee near the teeing ground.

This management building and a plurality of repeaters R1 to R1
Each of R11 is provided with a reception unit for a weak radio wave and a specific low-power transmitting / receiving device. The management building → repeater R1 → repeater R2 → repeater R3 → repeater R4.
A loop-shaped wireless communication network is configured so that information can be transmitted in the order of → repeater R10 → repeater R11 → management building. In other words, each repeater R1 to R1
1 is connected in a relay manner by wireless of a specific low power to exchange information, and in the meantime, each repeater R1 to R11 receives information from a golf cart acquired by receiving a weak radio wave,
Information to be passed is generated based on the received information, so that the receiver in the management building finally receives the position information of the golf cart and the like. This allows the management building to grasp the current position of the golf cart playing in each hole. In this wireless communication network, information is packetized and transmitted.

The management building and the repeaters R1 to R11
Has a unique identification code ID that does not overlap
0 to ID11 are given.
D0 is allocated, and the management building transmits a packet from a transceiver with specific low power by attaching an identification code ID1 allocated to the repeater R1 to which information is to be transmitted to a packet header. Note that the service range of the specific low-power radio wave transmitted from the management building is a limited range of several hundred meters, but the repeater R1 is disposed within the service range.

Then, a packet having the identification code ID1 of the repeater R1 in the packet header transmitted from the management building is transmitted only to the specific low-power transceiver of the repeater R1 to which the identification code ID1 is assigned among the repeaters R that received the packet. It will take in the received packets. Each of the golf carts K1 to K5 has its own identification code IDK1 to I5 so that any one of the repeaters R can recognize the current position.
The packetized information with DK5 is intermittently transmitted from a mounted weak radio wave transmitter at a specific cycle different for each golf cart K. The service area of the weak radio wave is about several tens of meters, and when the golf cart K moves and the repeater R is located in the service area, the repeater R can receive the weak radio wave. Therefore, when the golf carts K1 to K5 move around the teeing ground and the green of each hole, the repeater R provided there can receive. The repeater R, which has received the information transmitted by the golf cart K, adds the position information of the golf cart K to the packet transmitted from the management building to the next repeater R.
To the relay.

The golf carts K1 to K5 move through the holes as they play, and the golf carts K1 to K5
, A weak radio wave is transmitted at a specific cycle, but a plurality of repeaters R may receive a weak radio wave transmitted from one golf cart K depending on the arrangement position of the repeater R. In this case, the management building that finally receives the position information determines which hole is located in consideration of the starting order of the golf cart K and the layout of the course. Here, the repeater R1 is a golf cart K1 to K
If no weak radio wave is received from any of the above, the repeater R is added to the packet header of the packet transmitted from the management building.
By simply re-attaching the identification code ID2 of No. 2, it is transmitted from the built-in specific low-power transceiver.

As described above, the repeater R2 receives and takes in the packet transmitted by radio waves of a specific low power with the identification code ID2 of the repeater R2 added to the packet header. Then, when the weak radio wave is not received from any of the golf carts K1 to K5 similarly to the repeater R1, the same processing as described above is performed. That is, the identification code ID3 of the repeater R3 is re-attached to the packet header, and transmitted from the specific low-power transceiver incorporated in the repeater R2.

The packet transmitted from the repeater R2 is received and captured by the repeater R3, and the same processing as described above is performed. However, the repeater R3 is arranged in the middle of the fairway of the fourth hole. In this case, as shown in the figure, the golf cart K1 is moving on the fourth hole, and the repeater R3 is located within the service range.
The repeater R3 receives the weak radio wave transmitted intermittently by the golf cart K1. Based on the information transmitted by the weak radio wave, the repeater R3 adds the generated position information of the golf cart K1 to the packet transmitted between the repeaters. The ID4 of the repeater R4 is reattached to the packet header of this packet, and the packet is transmitted from the built-in specific low power transmitting / receiving device.

This packet is similarly transmitted to the repeater R4
Received and captured by Repeater R4 is Repeater R
3 is performed, but the position information of the golf cart K1 is already added to the packet received from the repeater R3. In this case, the repeater R4 is the golf cart K
Receive the weak radio wave transmitted from the
The same processing as in step 2 is performed. That is, the packet is transmitted from the built-in specific low power transceiver only by re-attaching the identification code ID5 of the repeater R5 to the packet header of the packet. The repeater R5 is arranged in the vicinity of the green of the third hole. In this case, since the golf cart K2 is moving on the green of the third hole as shown in the figure, the golf cart K2 is intermittent at a specific cycle. Is received by the repeater R5. The repeater R5 performs the same processing as the repeater R3, and adds the position information of the golf cart to the packet transmitted between the repeaters. The ID6 of the repeater R6 is reattached to the packet header of this packet, and transmitted from the built-in specific low power transmitting / receiving device.

Since the golf cart K is not located around the repeater R6 and does not receive the weak radio wave transmitted from the golf cart K, the repeater R7 is added to the packet header of the packet to which the position information of the golf carts K1 and K2 is added. ID
7 is re-attached and transmitted from the built-in specific low power transmitting / receiving device. This packet is received and received by the repeater R7. In this case, the repeater R7 is disposed near the teeing ground of the fifth hole, and in this case, the golf cart K3 is moving on the teeing ground of the fifth hole as shown.
Therefore, the repeater R7 receives a weak radio wave that the golf cart K3 is intermittently transmitting at a specific cycle. Based on the information transmitted by the weak radio wave, the repeater R7 adds the generated position information of the golf cart K3 to the packet transmitted between the repeaters. The ID of the repeater R8 is reattached to the packet header of this packet, and the packet is transmitted from the built-in specific low power transmitting / receiving device.

This packet is received and fetched by the repeater R8. In this case, the repeater R8 is disposed in the vicinity of the teeing ground of the second hole, but since the teeing ground of the second hole and the teeing ground of the third hole are close to each other, the repeater R8 has a length of five.
The weak radio wave transmitted by the golf cart K3 moving on the teeing ground of the number-th hole is received.
The repeater R8 adds the generated position information of the golf cart K3 to the packet transmitted between the repeaters.
The ID of repeater R9 is included in the packet header of this packet.
9 is re-attached and transmitted from the built-in specific low-power transmitting / receiving apparatus.

The information indicating the current position of the golf cart K is the identification code I of the repeater R that has received the weak radio wave.
This is performed by further adding D to the ID number of the golf cart K. This is because the position of the repeater R is fixed in advance, and the golf cart K
Because you can know the current location. By performing the above processing in the repeaters R1 to R11, the packet transmitted from the management building is transmitted in a relay manner to each of the repeaters R1 to R11, and during that time, each of the repeaters R1 to R11 is transmitted.
, The current position information of the golf carts K1 to K5 acquired is added to the packet.

In the case shown, the repeater R3 stores the current position information of the golf cart K1 playing in the fourth hole,
Golf cart K with repeater R5 playing in hole 3
2 and the repeater R7 presents the current position information of the golf cart K3 playing in the fifth hole.
10 acquires the current position information of the golf cart K4 playing in the second hole, and the repeater R11 acquires the current position information of the golf cart K5 playing in the first hole, and the respective repeaters R3, R5, R7, R10, R11. Adds this information to the packet and transfers the packet to the next repeater R in a relay manner. Accordingly, the management building that has received the packet from the repeater R11 can know the current positions of all playing golf carts K1 to K5 by decoding the packet, and perform operation management of the golf carts K1 to K5. Can be.

The management building and each of the repeaters R1 to R1
1 normally returns an ACK indicating that the packet has been normally received to the management building or any of the repeaters R1 to R11 when the packet destined for itself is normally received. If the packet has not been received normally, an NCK indicating that the packet has not been normally received is returned to the management building or any of the repeaters R1 to R11. As a result, the reliability of the looped wireless communication network is improved. As described above, in the second embodiment of the present invention, each of the repeaters R1 to R11 is provided with the transmission / reception device of a specific low power, so that the reach of the radio wave transmitted from each of the repeaters R1 to R11 is increased. Therefore, the number of repeaters can be reduced.

Next, FIG. 9 is a block diagram showing a schematic configuration of the transceiver 30 built in each repeater R.
