DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a blind is detected by a detector.
Figure shows a form that displays a danger of driving prohibited in a hall
This will be described with reference to FIG.

FIG . 1 shows a layout of a golf course.
However, for convenience of explanation, the number of holes is shown as 5 holes.
ing. However, the present invention is not limited to five holes.
9 holes, 18 holes or more
It can be. From the 1st hole to the 5th hole,
Golf carts K1-K5 are playing the hole.
You. As shown in this figure, the 4th hole is the left dogleg
It is a blind hole. Around the 4th hole
A detector D1 and a detector D2 are provided on the sides, and the detection is performed.
The output unit D1 is a slave unit, and the detector D2 is a master unit.

Golf carts K1 to K1 playing each hole
K5 is provided with a communication device for transmitting ID number information indicating its own cart number.
D number information is being transmitted. When the golf cart K1 playing the fourth hole approaches the detector D2, the detector D2 transmits an ID transmitted from the golf cart K1 at a constant period.
The number information will be received. Then, when the detector D2 receives the ID number information transmitted from the golf cart K1 at a constant period, the driving prohibition is displayed on the display 6 attached to the detector D2. This display is performed, for example, by turning on a red display.

The display 6 is installed at a position where it can be easily recognized from the teeing ground of the fourth hole. Therefore, even if the following party has reached the teeing ground, the display of the display 6 is blue. It will wait for a tee shot until it switches. Thereby, danger due to driving of the golf ball can be prevented in advance. Then, as the golf cart K1 proceeds through the fourth hole as the play progresses and passes through the detector D1, the detector D1 receives ID number information transmitted from the golf cart K1 at regular intervals, Golf cart K1
Is detected, the ID number information of the golf cart K1 is transmitted to the detector D2 of the parent machine.

The detector D2 receives this and checks whether or not another golf cart exists between the detector D1 and the detector D2. If there is no golf cart, the display of the display 6 is displayed. Make changes and leave tee shot permission to subsequent parties. The display is changed by, for example, turning on a red to blue indicator. Thus, safe play can be quickly performed even in a blind hole. Note that the detector D1 measures the electric field strength of the radio wave of the ID number information transmitted from the golf cart K1 at a constant cycle, and the golf cart K1 passes when the differential value of the electric field strength changes from positive to negative. Is to be detected.

FIG. 2 shows a block diagram of a communication device provided in the detector D1 and the detector D2. The detector D1, which is a slave unit, includes a receiver for receiving radio waves transmitted from the golf cart as shown in the figure, and a wireless transceiver 2 for transmitting the ID number of the golf cart that has passed the detector D2. And an antenna 5 for transmitting and receiving radio waves. The signal received by the wireless transceiver 2 is transmitted to the control processing circuit 3
The received ID number information is stored in a register or the like, and a detection process is performed to determine whether the golf cart has passed. Then, when the passage is detected, the wireless transceiver 2 transmits the ID number information stored in the register to the detector D2.

The detector D1 does not include the display 6. Furthermore, when the golf cart is provided with a communication device for weak radio waves, the receiver in the wireless transceiver 2 is a weak radio wave receiver, and the transmitter is a specific low power transmitter. When the golf cart is provided with a communication device for specific low power, the transceiver 2 is used as the specific low power transceiver 2. Furthermore, since the power consumption of the detector D1 is small,
The power source for operating the detector D1 can be local energy 4 such as a solar cell, and there is no need to wire a power line to the detector D1.

A detector D2, which is a parent device, includes a receiver for receiving radio waves transmitted from a golf cart as shown in the figure,
A wireless transceiver 2 including a receiver for receiving a radio wave transmitted from the detector D1 and an antenna 5 for receiving a radio wave are provided. That is, the wireless transceiver 2 does not need to include a transmitter. The signal from the golf cart received by the wireless transceiver 2 is sent to the control processing circuit 3,
The received ID number information is stored in a register or the like. The received signal from the detector D1 is also transmitted to the control processing circuit 3.
Is matched with the stored golf cart ID number information, and when matched, the display of the display 6 is changed to a display permitting a tee shot.

When the golf cart is provided with a communication device for a weak radio wave, the receivers in the radio transceiver 2 are a weak radio wave receiver and a specific low power receiver, and the golf cart has a specific low power receiver. In the case where a power communication device is provided, the wireless transceiver 2 is configured only with a receiver having a specific low power. Furthermore, since the power consumption of the detector D2 is small, the power source for operating the detector D2 can be local energy 4 such as a solar cell, and it is not necessary to provide a power supply line for the detector D2.

Next, a block diagram of a golf cart communication device provided in the golf cart is shown in FIG. As shown, the golf cart communication device includes a transmitter for transmitting ID number information, a radio transceiver 12 including a receiver, and an antenna 11 for transmitting and receiving radio waves. input/
Display Cart ID No. The unit 14 has its own cart number, IDNo. (ID number) and a display unit for displaying received information. The control processing circuit 13 performs processing such that transmission processing of the stored own ID number information is performed at a fixed cycle, and the ID number information is transmitted at a fixed cycle via the wireless transceiver 12 and the antenna 11. .

It is not always necessary to provide a receiver in the radio transceiver 12, and the radio transceiver 12 only needs to have a transmitter capable of transmitting an ID number at least at a constant period. Further, this transmitter may be either a weak radio wave transmitter or a specific low power transmitter. However, when the specific low power transmitter is used, the service area is several hundred meters, so that the golf cart is located anywhere in the blind hole. Detector D can detect it. Therefore, if the specific low power transmitter is provided, the golf cart can be applied to a system that runs freely on a fairway. In this case, even if the radio wave transmitted from the golf cart playing another hole is received by the detector D,
Since it can be recognized from the D number information that the golf cart is another golf cart, no malfunction occurs. Furthermore, as a power source for operating the communication device, a cart power source 15 such as a battery loaded on the golf cart is used.

Next, FIG. 4 shows an example of a data format for a golf cart to transmit ID number information at a constant period. This data format includes three areas, a first area D1 is a status data area of cart information including control flags and the like required for communication, and a second area D2 is a golf cart cart. No.
The third area D3 is an error detection code (CRC) area for detecting data errors.

FIG. 5 shows an example of a data format for transmitting ID number information from the detector D1 to the detector D2. As shown in this figure, the data area is composed of four areas, the first area D1 is a packet header area to which the ID number of the master unit (detector D2) to be received is attached, and the second area D1 is D2 is a status data area including control flags and the like required for communication, and a third area D3 is a data area for golf cart position information and includes golf cart ID number information. The fourth area D4 is an error detection code (CRC) area for detecting a data error.

Next, FIG. 6 shows a case in which a danger display of driving prohibition is performed in a blind hole using a detector. Although only one detector D is installed in this figure, a description of a configuration that is not different from the case of FIG. 1 will be omitted. A detector D and a display 6 are provided side by side at predetermined positions of the fourth hole, which is a blind hole. The display 6 is installed at a position visible from the teeing ground of the fourth hole. When the golf cart is present in the area indicated by the dashed circle around the detector D,
A display indicating that driving is prohibited is made on the display 6.

Whether or not the golf cart exists in the area shown by the dashed circle is determined by measuring the electric field strength of the radio wave received by the detector D. That is, 4
As shown in the drawing, the golf cart K1 is playing at the number hole, but when the detector D receives ID number information, which is the cart number information of the golf cart transmitted from the golf cart K1 at regular intervals, the detector D measures the electric field intensity, and when the electric field intensity is equal to or more than the predetermined value, determines that the golf cart is present in the area indicated by the dashed circle and displays a driving prohibition on the display 6. . Then, the electric field intensity of the radio wave transmitted from the golf cart K1 increases as the distance approaches, and the electric field intensity decreases when passing through the detector D.
Then, when the detector D detects that the electric field is lowered and becomes equal to or lower than the predetermined electric field intensity, the display of the display 6 is changed to notify the permission of the tee shot.

The detector D in the second embodiment
The communication device provided in the golf cart and the communication device provided in the golf cart have substantially the same configuration as that shown in FIG. 2 or FIG. 3, but are both communication devices having a specific low power. And
The detector D only needs to be provided with the specific low-power receiver, and the golf cart need only have at least the specific low-power transmitter. In this case, since the specific low power transmitter is provided in the golf cart, the golf cart can be applied to a system in which the golf cart travels freely on the fairway. In addition, even if the detector D receives a radio wave transmitted from a golf cart playing another hole, it can recognize that the golf cart is another golf cart from the ID number information. Does not malfunction. Furthermore, the data format of the data transmitted by the golf cart is as shown in FIG.

Next, when the repeater of the present invention is used,
Description of embodiments of the golf course ancillary equipment will be described with reference to FIG but Oite in this case the detection of the current position of the golf cart, and can be displayed prohibition implantation in blind holes. FIG. 7 shows the layout of the golf course, but for convenience of explanation, the number of holes is shown as 5 holes. 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 management building M and the plurality of repeaters R2 to R12 are in the first hole, the second hole,
Holes 3, 4, and 5 are located near the teeing ground and green of each hole. 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 them near the teeing ground. The fourth hole is a blind hole.

This management building M and a plurality of repeaters R2
To R12 are provided with specific low-power transmitting / receiving devices, respectively, in the order of management building M → repeater R2 → repeater R3 → repeater R4 → repeater R5... → repeater R11 → repeater R12 → management building M. A loop-shaped wireless communication network is configured to transmit information. That is, each repeater R2 to R12 is connected in a relay manner from the management building M by wireless of specific low power to exchange information, and during that time, each repeater R2 to R12 receives a radio wave of specific low power to obtain golf. Receive information from the cart,
Information to be passed is generated based on the received information, so that the receiver of the management building M finally receives the position information and the like of the golf cart. This allows the management building M to grasp the current position of the golf cart playing in each hole.

Further, using the communication network, the management building M transmits the operation order information of the golf cart on that day to each of the repeaters R2 to R2.
Notifying R12. This operation order information is notified by an ID number which is a cart number. In this case, if one party is composed of four bags of golf carts,
One cart number may be used, but two cart numbers are required for one party in the case of a two-bag golf cart, and four cart numbers are required in a one-bag golf cart. One cart number will be needed for one party. In the case where the golf cart is composed of a two-bag golf cart and a one-bag golf cart, three cart numbers are required for one party. Therefore, in order to notify all the cart numbers constituting one party, a party separation code is added to the end of the one party cart number.

To describe this with a specific example, in the case of a four-cart golf cart, the operation order of the golf carts is cart number 3, cart number 6, cart number 1, cart number 9, and cart number 2. When, for example, the operation order information notified from the management building M is
"03H, 00H, 06H, 00H, 01H, 00H,
09H, 00H, 02H, 00H ". The code “00H” in these codes is a party separation code. Further, when the golf club is composed of one bag of a golf cart, the cart numbers of a set of parties are cart number 9, cart number 3, cart number 7, and cart number 1.
The number of carts for the two parties is cart number 2, cart number 8, and cart number 22.
When the cart numbers of the three parties are four, that is, the cart number 13, the cart number 1, the cart number 6, and the cart number 15, the operation order information notified from the management building M is “09H, 03H, 07H, 11H,
00H, 02H, 08H, 22H, 00H, 13H, 0
1H, 06H, 15H, 00H ". The code “00H” in these codes is similarly a party separation code.

In this wireless communication network, information such as the operation order information is packetized and transmitted to each of the repeaters R2 to R12 by the wireless communication network.
Each of the repeaters R2 to R12 transmits the operation order information received from the next-stage repeater and each golf cart being played. In this case, the management building M and the repeaters R2 to R12 are given unique identification codes ID0 to ID11 which are not duplicated, and the management building M is assigned the recognition code ID0, Is attached to the packet header with the identification code ID1 assigned to the repeater R2 to which the packet is transmitted, and a packet composed of information such as operation order information is transmitted from the transceiver having the specified low power. Note that the service range of the specific low-power radio wave transmitted from the management building M is a limited range of several hundred meters, but the repeater R2 is disposed within the service range.

The packet having the identification code ID1 of the repeater R2 in the packet header transmitted from the management building M is the identification code ID1 of the repeater R that has received the packet.
Only the specified low power transceiver of the repeater R2 to which is assigned the received packet is fetched. Then, each golf cart K1 to K5 playing each hole
Receives the operation order information transmitted from the repeaters R2 to R12 so as to know the ID number of the golf cart of the preceding party from the operation order. In addition, the golf carts K1 to K5 receive packetized information with their own identification codes IDK1 to IDK5 in response to an inquiry made by the repeater at regular intervals in order to make the repeater R recognize the current position. Is sent back from the specific low power transmitter mounted.

The service area of the radio wave of the specified low power is about several hundred meters, and when the golf cart K moves and the repeater R is located in the service area, the repeater R moves from the golf cart K to the service area. The transmitted specific low-power radio wave can be received. The repeater R that 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 M, and transmits the packet to the next repeater R in a relay manner.

Note that the golf carts K1 to K5 move through the holes as they play, and when the golf cart K1 is playing at the fourth hole, which is a blind hole, as shown in FIG. Golf cart K1 in response to inquiries made at regular intervals from repeater R4
Is received by the repeater R4. At this time, the radio wave transmitted by the golf cart K1 is received by the subsequent golf cart, and the current position of the preceding golf cart is known from the electric field intensity of the radio wave. The operation order information is notified to each golf cart K from the repeater R as described above, and the operation order information is compared with the received golf cart ID number information to constitute a preceding party. The golf cart K of the succeeding party detects all current positions of the golf cart.

In the illustrated case, the golf cart is a four-bag golf cart, so that one party is one golf cart. However, in the case of a one-bag golf cart, up to four golf carts are used. When one party is composed of four golf carts, for example, the golf cart K of the succeeding party is formed.
Performs detection of all four golf carts. Then, when it is determined that the positions of all golf carts constituting the preceding party are separated by a safe distance, the subsequent golf cart displays a tee shot permission display on the display provided. Do. At this time, the player may also be notified by sound. In this case, the driving prohibition is displayed on all the golf carts of the following party until all the golf carts constituting the preceding party are separated from the golf cart of the following party by a safe distance.

Note that the cart number of the golf cart of the preceding party can be known from the operation order information already notified from the repeater R. In addition, the fact that all golf carts that make up the preceding party are separated from the golf cart of the following party by a safe distance means that the golf cart of the following party reduces the electric field strength of radio waves transmitted from the preceding party. It is determined by measuring. Furthermore, the golf cart K is a repeater R
, The position information of the preceding golf cart K may be obtained. When a plurality of repeaters receive radio waves transmitted from one golf cart, it is determined that the golf cart is located near the repeater that has received the radio waves having the highest electric field intensity. In this case, the exchange of information between the repeaters is performed using the above-mentioned loop-shaped wireless communication network.

Next, when the repeater of the present invention is used,
An outline of an embodiment of another golf course incidental facility will be described with reference to FIG. This embodiment is characterized in that the communication device provided in the golf cart is a communication device for weak radio waves,
The difference is that the repeater is further provided with a receiver for a weak radio wave, and the blind hole is provided with the display device 6, and the other configuration is the same. Just do next.

This management building M and a plurality of repeaters R2
To R12 are provided with specific low-power transmitting / receiving devices, respectively, in the order of management building M → repeater R2 → repeater R3 → repeater R4 → repeater R5. A loop-shaped wireless communication network is configured to transmit information. That is, the repeaters R2 to R12 are connected in a relay manner from the management building M by wireless of specific low power to exchange information, and in the meantime, each repeater R2 to R12 receives a weak radio wave to obtain information from the golf cart. The information is received, and information to be transferred is generated based on the received information, so that the receiver of the management building M finally receives the position information and the like of the golf cart. This allows the management building M to grasp the current position of the golf cart playing in each hole.

Further, using the communication network, the management building M transmits the operation order information of the golf cart on that day to each of the repeaters R2 to R2.
Notifying R12. This operation order information is notified by an ID number which is a cart number. In this case, if one party is composed of four bags of golf carts,
There is one cart number, but if it is composed of two bags of golf carts, one party is composed of two cart numbers, and if it is composed of only one bag of golf carts, four parties are used. One party is constituted by the cart number. In the case where the golf cart is composed of a two-bag golf cart and a one-bag golf cart, one party is composed of three cart numbers. Therefore, in order to notify all the cart numbers constituting one party, a party separation code is added to the end of the one party cart number as described above.

The packet having the identification code ID1 of the repeater R2 in the packet header transmitted from the management building M is the identification code ID1 of the repeater R that has received the packet.
Only the specified low power transceiver of the repeater R2 to which is assigned the received packet is fetched. Then, each golf cart K1 to K5 playing each hole
Transmits the ID number information of its own cart number by a weak radio wave at regular intervals. The repeater R that has received the weak radio wave determines that the golf cart is located near the repeater R. Thereby, the golf carts K1 to K
5 allows any of the repeaters R to recognize the current position.

In this case, the service area of the radio wave of the specific low power is about several hundred meters, but the service area of the weak radio wave is several tens of meters. Therefore, the golf cart K moves and the repeater R moves to the service area. Is located, the repeater R can receive the weak radio wave transmitted from the golf cart K. The repeater R that 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 M, and transmits the packet to the next repeater R in a relay manner.

Note that the golf carts K1 to K5 move through the holes as they play, and when the golf cart K1 is playing in the fourth hole, which is a blind hole, as shown in FIG. ID number IDK at which repeater R4 is transmitted from golf cart K1 at regular intervals
Assume that 1 has been received. At this time, the repeater R4 determines that the golf cart K1 is in the vicinity, and displays a driving prohibition on the display 6. The subsequent party looks at the display on the display 6 and waits for a tee shot. Then, when the repeater R4 stops receiving the radio wave transmitted from the golf cart R1, the repeater R4 displays the tee shot permission on the display 6.

The repeater R4 detects whether or not radio waves transmitted from all golf carts constituting one party can be received. In the illustrated case, the repeater R4 is a four-bag golf cart. It monitors the radio waves of one golf cart. In the case of a one-bag golf cart, the preceding party is constituted by a plurality of golf carts of up to four. For example, when one party is constituted by four golf carts, all of the four golf carts are arranged. Monitoring of radio wave transmitted from golf cart repeater R4
Do. Then, when the radio waves transmitted from all the golf carts constituting one party are no longer received, the repeater R4 displays a tee shot permission on the display 6 attached thereto.

The cart number of the golf cart constituting one party can be known from the operation order information already notified from the management building M. By the way, when a plurality of repeaters receive radio waves transmitted from one golf cart, it is determined that the golf cart K is located near the repeater R which has received the radio waves having the highest electric field intensity. In this case, the exchange of information between the repeaters R is performed using the above-described loop-shaped wireless communication network.

[0053] In addition, golf cart for communication machine definitive in another embodiment of the present invention is provided with a transmitter of weak radio waves. Therefore, the wireless transceiver 12 is composed of at least a weak radio wave transmitter. In this case, a specific low power receiver may be provided, and information notified from the management building M via the repeater R may be received. The display unit 25 does not need to be particularly provided, but when provided, may display information notified from the management building M.

Next, FIG. 11 schematically shows a loop-shaped radio communication network in the third embodiment shown in FIG.
In this figure, the management building M (31) and the repeater R2
(32) to the repeater R5 (35) form a loop-shaped wireless communication network. That is, management building M (31) →
Repeater R2 (32) → Repeater R3 (33) → Repeater R4 (34) → Repeater R5 (35) → Management building M (3
A wireless communication network is formed by connecting in the order of 1) by radio waves of specific low power. However, this case shows a case where the number of repeaters is four.

For example, the golf cart 37 is located near the repeater R2, and an information transmission / transmission request is sent from the repeater R2 to the golf cart 37, and the ID number information of the golf cart 37 is returned in response to the request.
Has been sent to. In addition, the golf cart 38 is located near the repeater R4, and an information transmission / transmission request is transmitted from the repeater R4 to the golf cart 38.
The D number information is sent to the repeater R4. The ID number information sent from the golf carts 37 and 38 is transmitted to the management building 31 via a loop-shaped wireless communication network, and the management building 31 displays the current position of each golf cart, information from each golf cart, or each of the golf carts. Information to the golf cart can be managed.

Next, FIG. 12 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 figure shows a case where the golf cart 37 transmits information in response to an information transmission request from the repeater R2, and this information transmission signal is received by the repeater R2, the repeater R3, and the repeater R4. In this case, the received electric field strength of the radio wave received by the
Assume that the received electric field strength of the radio wave received by the receiver 3 is medium and the reception intensity of the radio wave received by the repeater R4 is weaker.
In general, it is assumed that the stronger the received electric field strength, the closer the position is. Therefore, in this case, it is determined that the golf cart 37 is located closest to the repeater R2 (32),
2 receives the information transmission signal.

More specifically, when the repeater R2, which has made an information transmission request to the golf cart 37, receives the response signal transmitted from the golf cart 37 and recognizes the radio wave, when the repeater R2 recognizes the radio wave, the packet is transmitted between the repeaters. Then, the packet is transmitted with the information on the position of the golf cart added thereto and the information on the electric field strength of the received radio wave. Then, the next repeater R3 receiving the packet similarly makes an information transmission request to the golf cart 37, and performs the same processing as the previous repeater R2. Where the previous repeater R
The golf cart 37 already exists in the packet received from
The repeater R3 compares the information on the electric field strength with the information on the electric field strength received by the repeater R3. Is rewritten, and the packet is transmitted to the next repeater R4. In the case shown in the figure, the above processing is not performed because the electric field strength of the repeater R2 is higher, and the data of the packet is transferred to the next repeater as it is.

As another method, the golf cart 3
7 to receive the 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 R2, the recognition code I of the golf cart 37
By adding the identification code ID1 of the repeater R2 to the DK, the current position information of the golf cart 37 is created, and the packet is transmitted to the next repeater R3. Further, the above-described processing is performed on the golf cart 38. In this case, if the golf cart 37 is the golf cart of the preceding party and the golf cart 38 is the golf cart of the subsequent party, the golf cart 3
8 measures the electric field strength of the radio wave transmitted by the golf cart 37. Then, the distance of the golf cart 38 is detected from the electric field strength as described above.

Next, FIG. 13 shows a data format of transmission / reception of the golf cart K. As shown in this figure,
The data format is composed of three areas, a first area D1 is a status data area of cart information such as control flags required in a communication network, and a second area D2 stores a cart number at the time of transmission. When receiving, it is a cart operation order information data area. The third area D3 is an error detection code (CRC) area for detecting a data error.

FIG. 14 shows an example of the data format between the repeaters R. As shown in this figure, the data area is composed of six areas, the first area D1 is a packet header area with the ID number of the repeater to be received, and the second area D2 is necessary for the communication network. The third area D3 is a data area transmitted from the management building to the golf cart, and can be transmitted individually to the golf cart. The data can also be broadcast to golf carts. The fourth area D4 is an area in which data to be sent to the management building M received from the golf cart K while the packet is being relayed by the repeater is incorporated. The fifth area D5 is a data area to which cart position information, electric field strength information, and cart operation order data are sent. Further, the sixth area D6 is an error detection code (CRC) area for detecting data errors.

Further, when the weak radio wave transmitted by the golf cart K is received from the weak radio wave antenna 43 provided only in the fourth embodiment, the weak radio wave receiving unit 44 demodulates the weak radio wave and sends it to the CPU 45. This demodulated data is written into the RAM 41.

Further, when the specific low power radio wave transmitted from the golf cart is received from the repeater R, the management building M, or the third embodiment only from the specific low power antenna 46, the specific low power transmitting / receiving section 47 Receives this, demodulates it and sends it to the CPU 45. The CPU 45 reads the repeater number set by the repeater number setting switch 48, compares the read repeater number with the ID number in the packet demodulated by the specific low power transmitting / receiving unit 47, and determines whether the packet is received by the repeater. If the repeater number and the ID number do not match and it is determined that the packet is not a packet received by the repeater, the packet is discarded, the repeater number and the ID number match, and it is determined that the packet is received by the repeater. The CPU 45 performs a process of transmitting the packet to the next repeater R.

That is, the demodulated packet is added to the RAM
The position information obtained by adding the repeater number of the repeater is added to the information from the golf cart K written in 41, the ID number of the next repeater R is re-attached to the packet header, and the packet is transmitted to the specific low power transmitting / receiving unit 47.
