One of the best activities. Therefore, whenever a holiday comes, many relatives, friends, families, or companies will travel together to connect each other's emotions. Due to the advancement of the economy and technology, the accompanying travel is by car, so a group of vehicles is formed under many vehicles.

Usually, when the team starts, in order to avoid some vehicles to lose, or take the wrong route, each car will be equipped with a radio or mobile phone to communicate, or use the satellite navigation system to guide the purpose. Although radios and mobile phones can link the communication between the vehicle and the vehicle, during the driving process, each car must always look at the rearview mirror to see if the car is following up. If the car is not followed by the car. When you are on, you will be notified that the preceding car is parked on the side of the road, waiting for the vehicle that has not been kept up, or notifying the unfollowed vehicle with the wireless walkie-talkie. This mode of following the car is not only troublesome, but also easy to cause traffic accidents. Even after being separated from the vehicle, the satellite navigation system on the vehicle can be used to guide the destination. However, the satellite navigation system currently used by the vehicle can only see its position, cannot see other vehicle positions in the fleet, and itself and How far is the team gap?

In addition, the occurrence of mountain disasters is usually caused by mountain climbers who are unfamiliar with the mountain roads or physical injuries. Once the mountain climber has a mountain disaster, he can't send the location signal for help in the first time. He must wait until the mountain manager finds that the climber has not returned within the specified time, and will notify the rescue unit to rescue. When the rescue unit was rescued, it was impossible to know the location of the mountain climber, and the rescuer had to search and rescue the entire mountain, resulting in a long search and rescue time, which caused the climber to die.

Please refer to the second and third figures, which is a schematic diagram of the use of the communication positioning device and the mobile device connection block and the hand-held mobile positioning device. As shown in the figure: In this creation, a plurality of handheld mobile positioning devices are used for multi-to-many cross communication positioning allocation. After each handheld mobile device is connected, one of the devices is a master 6 and the remaining devices are Slave 7. Therefore, this creation is only described herein with respect to two or three communication positioning devices.

When the first device and the second device enter the search, the search for the auxiliary device data is sent, and the search function of the function processing unit 101 is passed to the scheduling processing unit 19 to control the wireless transmission and reception control unit 12 to perform the transmission and reception of the search function at an appropriate time. When the first device (No. 001) receives the signal of the second device (No. 002), the micro-processing core 11 performs the number value (ID) comparison of the two devices, and the number (ID) of the second device is compared with the number A device is high, so the first device is a slave 7 and the second device is a master 6 (the ID value comparison method is changed to a low ID master according to the system). When the host 6 is ready to receive the slave 7 signal, the host 6 first sends a signal to the slave 7, and the slave 7 replies the signal to the host 6. After receiving the reply signal, the host 6 sends a reply signal to the slave 8 to complete. link.

When the host 6 is not a slot, it jumps to the search and sends a seek device. When the slave 8 is not a slot, it jumps to the device to search for a new device. (When a third device with a number 003 is connected, each device starts the comparison number (ID) through the micro processing core 11, and the highest ID is the master. Therefore, the first device is the slave and the second device is the slave. Machine, the three devices are the host.)

When the host 6 performs the search, the random number generating unit 18 generates a time slot (Slot) in the search channel, and the search function of the function processing unit 101 transmits a search slave 7 signal through the communication interface unit 102 to search for the missing. The slave machine 7 receives the reply signal from the search slave 7 at the host 6, transmits the received signal to the slave 7, and the slave 7 sends a reply signal to the host 6 when receiving the search slave 7 signal of the host 6. Confirm the signal sent by the host 6 to complete the search mode.

When the slave 7 calls the host 6, the search function of the function processing unit 101 is sent to the host 6 by the scheduling processing unit 19 to control the wireless transmission and reception control unit 12 to perform the search function at the appropriate time. The host 6 receives the call host 6 signal of the slave 7, calculates the relative distance and position of the host 6 and the slave 7, and replies the signal to the slave 7, that is, completes the call of the host 6 and the slave 7.

When the host 6 receives the signal strength indicator value is too small, or the data loss in the same period (Slot) is too large, it enters the frequency hopping mode through the frequency hopping unit 16, and is processed by the function processing unit 101. The unit 19 controls the radio transmission and reception control unit 12 to start searching for the transmission period of the host 6 of all channels at an appropriate time to see if there is an available channel, and the available channel is searched for, and is transmitted by the radio transmission receiving control unit 12 and the radio transmission receiving circuit 2. The channel hopping signal informs all of the slaves 7 to perform frequency hopping, and the slave 7 starts hopping.

The host 6 receives the data of the slave 7, and calculates the latitude and longitude values and the received signal strength indicator values. And determining whether the transmit power of the slave 7 needs to be adjusted. If the transmit power of the slave is adjusted, the transmit power adjustment unit 15 sends the adjusted power signal to the slave 7 via the wireless transmit and receive control unit 12 and the wireless transmit and receive circuit 2 to Adjust the transmit power. After the slave 7 receives the transmission power adjustment signal transmitted by the host 6, the slave 7 adjusts the transmission power according to the transmission power of the adjustment slave 7.

When the host 6 makes an emergency call, the emergency processing mode is entered via the function processing unit 101, and all the functions being used are turned off at this time. The scheduling processing unit 19 adjusts the transmission of the emergency call signal according to the remaining power of the battery. When the emergency call mode is turned off, the emergency call mode is completed and all functions are open. In the emergency call of the slave, similarly, all the functions being used are turned off, and the scheduling processing unit 19 adjusts the emergency call signal according to the remaining power of the battery. After the emergency call mode is turned off, the emergency call mode is completed, and all functions are completed. open.

In the normal mode, the host 6 can be turned on by the function processing unit 101 to search for an emergency call signal. When the host 6 is turned on, the search emergency call mode is entered, and if the time slot (Slot) is not in the work mode, it is received on the emergency call channel. If it is determined that an emergency call (Emergency SOS) is received, the latitude and longitude of the sender is locked, and the location of the sender is calculated.

In the normal mode, the host 6 generates a time via the timing unit 17, and the scheduling processing unit 19 is fixedly transmitted to the slave 7 according to the time generated by the timing unit 17, so that the slave 7 knows that the host 6 still exists and the slave 7 and the host are conveniently located. 6 pairs of hours.

If the host 6 and the slave 7 are never paired, the host generates a slot (Slot) in the connected channel by the random number generating unit 18, and the scheduled processing unit according to the generated time slot (Slot) 19 Controlling the wireless transmission and reception control unit 12 to transmit the connection signal at an appropriate time, and receiving it at other time slots (Slots). If the connection reply signal of the slave device 7 is received, the host 6 and the slave unit 7 are paired.

Please refer to the fourth figure, which is a schematic diagram of another use state of the handheld mobile positioning device of the present invention. As shown in the figure: if the two hosts 6, 6' have never been paired, the first host 6 generates a time slot (Slot) in the connected channel by the random number generating unit 18, and sends a link signal according to the generated time slot (Slot). Receiving in other time slots (Slot), if the connection signal of the second host 6' is received, the comparison number (ID) is performed, and if the ID of the first host 6 is relatively high as the host after the comparison, the second host 6' is the vice Machine (The ID value comparison method is changed to the low ID to Master according to the system).

It is determined whether the first host 6 receives the link reply signal of the second host 6', and if it receives the link reply of the second host 6', and transmits the link completion signal to the second host 6'. Similarly, the second host 6' also generates a time slot (Slot) in the connected channel by the random number generating unit 18, and sends a link signal according to the generated time slot (Slot). If the link signal of the first host 6 is received, Comparing the number (ID), the ID of the first host 6 is relatively high as the host, and the second host 6' is the slave, and the second host 6' sends the link reply signal again to complete the pairing.
