In step 51, the processing unit 33 of the server 3 receives at least one of the object information from the receiving end 1 via the communication unit 31 at a current time, according to the at least one object at the current time. Information, and at least one of the previous object information (that is, the previous object information stored last time in the storage unit 32) corresponding to the at least one item information, and determining whether there is at least one item information to be confirmed, The location information of each of the to-be-identified object information at the current time is different from the previous location information in the previous object information corresponding thereto. When the processing unit 33 of the server 3 determines that the at least one object information to be confirmed exists, the process proceeds to step 52; when the processing unit 33 of the server 3 determines that the at least one object information to be confirmed does not exist, the process proceeds. Step 55.

In step 52, the processing unit 33 of the server 3 determines whether a status flag corresponding to the object identification information of each item information to be confirmed is the first predetermined value. When the processing unit 33 of the server 3 determines that the status flags corresponding to the object identification information of each item information to be confirmed are not all of the first predetermined value, the process proceeds to step 53; when the processing of the server 3 is performed When the unit 33 determines that the status flag corresponding to the object identification information of each item information to be confirmed is the first predetermined value, the process proceeds to step 55.

When the processing unit 33 of the server 3 determines that the location information corresponding to the object information to be confirmed that the status flag is not the first predetermined value is not located in the bicycle return position, the flow proceeds to step 54; When the processing unit 33 of the server 3 determines that the location information corresponding to the object information to be confirmed that the status flag is not the first predetermined value is located in the bicycle return position, the flow proceeds to step 55.

In step 54, the processing unit 33 of the server 3 outputs an abnormality message indicating that the location information corresponding to the current time is not located in the bicycle returning position, and stores the at least one object of the current time. Information is sent to the storage unit 32.

In step 55, the processing unit 33 of the server 3 stores the at least one item information of the current time to the storage unit 32.

For example, suppose the public bicycle supplier has three bicycles to rent, the object identification data of the bicycles are A001, A002 and A003, respectively, and the coordinate position of the bicycle return position is (0, 0). The senders 2 are simultaneously activated at 8:00:00, while the bicycles numbered A001 and A002 are rented out at 8:15:50, and the bicycle numbered A001 is returned at 8:16:30. Then, the transmitting end 2 of the bicycles are mounted at the transmitting time and the coordinate position of the bicycles as shown in the following Table 1. The transmitting end 2 corresponding to the bicycle numbered A001 is hereinafter referred to as the first transmitting end 2. The transmitting end 2 corresponding to the bicycle numbered A002 is referred to as the second transmitting end 2, and the transmitting end 2 corresponding to the bicycle numbered A003 is referred to as the third transmitting end 2 so as to distinguish the transmitting ends 2. Table 1

After the sending end 2 and the third transmitting end 2 respectively send the object information sent by 8:00:01, 8:00:02, 8:00:03, the receiving end 1 transmits the object information via the communication network 4. Up to the server 3, when the server 3 receives the object information from the receiving end 1 via the communication unit 31 at a current time, for example, 8:00:04, storing the object information to the storage unit. 32. Then, the receiving end 1 receives the first transmitting end 2, the second transmitting end 2, and the third transmitting end 2 via different long-distance wireless networks at 8:15:01, 8:15:02 respectively. After the object information sent by 8:15:03, the receiving end 1 transmits the object information to the server 3 via the communication network 4, and when the server 3 is at a current time, for example, 8:15:04 After the communication unit 31 receives the object information from the receiving end 1, the server 3 compares the object information corresponding to the object information and the previously stored previous object information according to the object information at the current time ( That is, the previous object information stored at around 8:00:04, to determine whether there is at least one item information to be confirmed. Since the bicycles are not rented, the location of the bicycles is not changed. Therefore, the server 3 determines that the at least one object information to be confirmed does not exist, and stores the objects received at the current time. Information is sent to the storage unit 32.

Then, the bicycles numbered A001 and A002 are rented out at 8:15:50 at the same time. At this time, the first transmitting end 2 and the second transmitting end 2 are switched to be at different sending times (for example, 8:16:01). , 8:16:02 and 8:16:21, 8:16:22) and according to the second cycle (8:16:01 after the transmission is separated by 20 seconds, 8:16:02 after the transmission is separated by 20 Second) periodically transmits the corresponding object information to the receiving end 1, and the third transmitting end 2 is still periodically transmitted in the first period (15 minutes after the 8:15:03 transmission) Corresponding object information is sent to the receiving end 1. The receiving end 1 receives the object information sent by the first transmitting end 2 and the second transmitting end 2 at 8:16:01 and 8:16:02 respectively through different long-distance wireless networks, and the receiving end 1 receives the information of the object transmitted by the first transmitting end 2 and the second transmitting end 2 respectively at 8:16:01 and 8:16:02. The terminal 1 transmits the object information to the server 3 via the communication network 4, and the server 3 receives the objects from the receiving terminal 1 via the communication unit 31 at a current time, such as 8:16:04. After the information, the server 3 according to the object information at the current time, and the previous object information corresponding to the object information and previously stored (that is, the previous object information stored around 8:15:04) ), determining whether there is at least one piece of information to be confirmed. The coordinate position corresponding to the current time position information corresponding to the object identification information A001 is (1, 0), and the coordinate position corresponding to the previous position information in the previous object information is (0, 0), and corresponds to The coordinate position corresponding to the position information of the current time of the object identification information A002 is (0, 1), and the coordinate position corresponding to the previous position information in the previous object information is (0, 0), so the servo end 3: It is determined that there are two pieces of information to be confirmed, and then the server 3 determines whether a status flag corresponding to the object identification information of each item information to be confirmed is the first predetermined value. Since the bicycles numbered A001 and A002 are rented out at 8:15:50 at the same time, the servo terminal 3 receives a bicycle related to the numbers A001 and A002 at 8:15:50 and contains the identification information of the objects (also That is, after the rental request of A001 and A002), the flag value of the status flag corresponding to the object identification information (ie, A001, A002) is updated to the first predetermined value. Therefore, the server 3 determines that the status flag corresponding to the object identification information (ie, A001, A002) of each item information to be confirmed is the first predetermined value, and stores the object information of the current time. To the storage unit 32. Similarly, the receiving end 1 receives the object information sent by the first transmitting end 2 and the second transmitting end 2 at 8:16:21 and 8:16:22 respectively via different long-distance wireless networks. The receiving end 1 transmits the object information to the server 3 via the communication network 4, and the server 3 receives the slave terminal 1 via the communication unit 31 at a current time, such as 8:16:24. After the object information, the server 3 stores the previous object information corresponding to the object information and stored in the previous information according to the object information at the current time (ie, stored at around 8:16:04). The previous object information) determines whether there is at least one item information to be confirmed. The coordinate position corresponding to the current time position information corresponding to the object identification information A001 is (1, 1), and the coordinate position corresponding to the previous position information in the previous object information is (1, 0), and corresponds to The coordinate position corresponding to the position information of the current time of the object identification information A002 is (0, 2), and the coordinate position corresponding to the previous position information in the previous object information is (0, 1), so the servo end 3: It is determined that there are two pieces of information to be confirmed, and then the server 3 determines whether a status flag corresponding to the object identification information of each item information to be confirmed is the first predetermined value. When the server 3 determines that the status flag corresponding to the object identification information (ie, A001, A002) of each item information to be confirmed is the first predetermined value, the server 3 stores the current time. The object information is sent to the storage unit 32.

Then, the bicycle numbered A001 is rented back at 8:16:30. At this time, the first transmitting end 2 switches back to its corresponding transmission time (eg, 8:30:01) and according to the first period. (The transmission after 8:30:01 is separated by 15 minutes) periodically sends the corresponding object information to the receiving end 1, and the second transmitting end 2 remains in the second period (8:16:22) The transmission is periodically sent for 20 seconds to periodically transmit the corresponding object information to the receiving end 1. The process of the second transmitting end 2 transmitting its object information to the receiving end 1 is substantially similar to the foregoing process, and therefore will not be described again. The following shows directly that the receiving end 1 receives the first transmitting end 2, the second transmitting end 2, and the third transmitting end 2 via 8:30:01 and 8:30 respectively via different long-range wireless networks: 02, 8:30:03 after the object information sent by the process, the receiving end 1 receives the first transmitting end 2, the second transmitting end 2 and the third transmitting end 2 respectively at 8:30:01 After the object information sent by 8:30:02 and 8:30:03, the information of the object is transmitted to the server 3 via the communication network 4, when the server 3 is at a current time, for example, 8:30: After receiving the information of the object from the receiving end 1 via the communication unit 31, the server 3 compares the object information corresponding to the object information and the previously stored previous object according to the object information at the current time. Information (that is, the previous object information stored at 8:16:24 corresponding to the first sender 2, the previous object information stored at 8:29:44 corresponding to the second sender 2, and At 8:15:04, the previous object information corresponding to the third transmitting end 2 is stored, and it is determined whether there is at least one piece of information to be confirmed. Since the coordinate position corresponding to the current time position information corresponding to the object identification information A001 is (0, 0), the coordinate position corresponding to the previous position information in the previous object information is (1, 1), and the number is The bicycle of A002 has not been returned yet. It is assumed that the position information corresponding to the position information of the current time of the object identification information A002 is (10, 8) and the coordinate position corresponding to the previous position information in the previous object information is (10, 7). Therefore, the server 3 determines that there are two pieces of information to be confirmed, and then the server 3 determines whether a status flag corresponding to the object identification information of each item information to be confirmed is the first predetermined value. Since the bicycle numbered A001 is returned at 8:16:30, the server 3 receives a return request for the bicycle associated with the number A001 at 8:16:30 and contains the object identification information (ie, A001). Then, the flag value of the status flag corresponding to the object identification information (ie, A001) is updated to the second predetermined value. Therefore, the server 3 determines that the status flags corresponding to the object identification information (ie, A001, A002) of each object information to be confirmed are not all of the first predetermined value, and therefore, the server 3 then determines the corresponding Whether the state flag is not the first predetermined value of the object information to be confirmed, and the location information at the current time is located at the bicycle return position. Since the coordinate position corresponding to the position information of the current time corresponding to the object identification information A001 is (0, 0) is located at the bicycle return position, the server 3 determines that the corresponding status flag is not the first reservation. The position information of the current item to be confirmed is located at the bicycle return position, and stores the at least one item information of the current time to the storage unit 32.

In summary, the data transmission system of the present invention periodically transmits the corresponding communication module 22 by one of the first period and one of the second periods shorter than the first period. Sending the corresponding object information to the receiving end 1 via the corresponding long-distance wireless network, wherein each item information includes the location information, the power information, the speed information, the motor information, and the air quality information, thereby The bicycle can be managed and maintained according to the information stored in the server 3, for example, the supplier of the public bicycle can determine whether the bicycle needs to be charged by using the power information in the information of the object, without At the moment, the rental of the bicycle is checked one by one. In addition, the position information corresponding to the current time is determined by the server 3 to be different from the previous position information and not located at the bicycle return position, and the corresponding status flag is When the information of the object to be confirmed is not the first predetermined value, the server 3 outputs a position indicating that the location information corresponding to the current time is not located at the bicycle returning position. An abnormal message of the object information is confirmed to remind the supplier of the public bicycle that the bicycle is stolen, so that the object of the present invention can be achieved.
