[0042] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0043] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0044] Figure 1 This is the first flow chart of the network address dynamic configuration method of the present invention. This embodiment proposes a network address dynamic configuration method, the method comprising:

[0045] S1. Calculate the minimum and maximum values ​​of the integers corresponding to all valid addresses in the current network according to the address input to the current network and the number of bits of the subnet mask;

[0046] S2, converting each integer in the integer range formed by the minimum value and the maximum value into the corresponding effective address, and adding all the effective addresses to a preset address list;

[0047] S3. Excluding the connected addresses of the first aircraft in the connected state from the address list according to a preset configuration period, and performing a connection operation of the second aircraft in the unconnected state according to the remaining addresses.

[0048] In this embodiment, the current network is a local area network supporting IPv4 as an example for explanation. First, the 4 bytes of the address input to the current network are parsed and recorded as a, b, c, d, and the number of subnet mask bits corresponding to the above address input to the current network is parsed and recorded as maskBits; then, the integer composed of the 4 bytes of the address input to the current network is calculated, recorded as address, where the calculation formula of address is address = (a<<24)+(b<<16)+(c<<8)+d; finally, the minimum and maximum values ​​of the integers corresponding to all valid addresses in the current network are calculated according to the above integers, where the minimum value is recorded as min and the maximum value is recorded as max.

[0049] In this embodiment, after the minimum value min and the maximum value max are calculated, for all integers i in the integer range [min, max], its 4 bytes are obtained and converted into corresponding IP addresses, and these IP addresses are added to the address list list as valid addresses.

[0050] In this embodiment, after obtaining the address list list, the connected addresses of the aircraft in the connected state are excluded from the address list according to the preset configuration cycle, and the connection operation of the aircraft in the non-connected state is performed according to the remaining addresses, wherein the aircraft in the connected state is recorded as the first aircraft, and the aircraft in the non-connected state is recorded as the second aircraft; further, the aircraft that was once in the connected state and is now in the non-connected state is still regarded as the first aircraft, so that when the aircraft resumes communication with the ground station, it can re-establish the connection.

[0051] The beneficial effects of this embodiment are that the minimum and maximum values ​​of the integers corresponding to all valid addresses in the current network are calculated by inputting the address and subnet mask bits of the current network; each integer in the integer range formed by the minimum value and the maximum value is converted into the corresponding valid address, and all the valid addresses are added to the preset address list; the connected address of the first aircraft in the connected state is excluded from the address list according to the preset configuration cycle, and the connection operation of the second aircraft in the non-connected state is performed according to the remaining address. A convenient, efficient and accurate network address dynamic configuration and access solution for unmanned aerial vehicles is realized, which reduces the manpower and material costs of the configuration link and enhances the flexibility of the access link.

[0052] Figure 2 is a second flow chart of the network address dynamic configuration method of the present invention, based on the above embodiment, the minimum and maximum values ​​of the integers corresponding to all valid addresses in the current network are calculated according to the address input to the current network and the number of bits of the subnet mask, including:

[0053] S11, receiving the address of the current network and the number of bits of the subnet mask input by the user;

[0054] S12. Analyze and obtain the bytes and bits corresponding to the address and the subnet mask bits respectively.

[0055] Optionally, in this embodiment, the parameter "192.168.2.0 / 23" input to the current network is taken as an example for description, wherein the address of the parameter is "192.168.2.0" and the number of subnet mask bits of the parameter is "23".

[0056] Optionally, in this embodiment, the address of the above parameter "192.168.2.0 / 23" is 4 bytes, that is, 32 bits.

[0057] Figure 3 The third flow chart of the network address dynamic configuration method of the present invention is based on the above embodiment, and the minimum and maximum values ​​of the integers corresponding to all valid addresses in the current network are calculated according to the address input to the current network and the number of bits of the subnet mask, and also includes:

[0058] S13, calculating a mask according to the byte and the number of bits;

[0059] S14. Calculate the minimum value and the maximum value according to the integer composed of the bytes and the mask.

[0060] Optionally, in this embodiment, according to the calculation formula address = (a<<24) + (b<<16) + (c<<8) + d, the integer form of the current address is calculated, wherein the symbol "<<" represents a binary left shift, and a left shift of 8 bits is equivalent to multiplying by 2 to the 8th power. At the same time, the above 24, 16, and 8 are the number of bits of 3 bytes, 2 bytes, and 1 byte, respectively. Based on this, the result of the above entire formula is the integer form of this address. Specifically, for example, (192<<24)+(168<<16)+(2<<8)+0=192*224+168*216+2*28+0=3232236032.

[0061] Optionally, in this embodiment, according to the calculation formula mask=0xFFFFFFFFu<<(32-maskBits), a mask is calculated and recorded as mask.

[0062] Optionally, in this embodiment, the minimum value and the maximum value are calculated according to the calculation formulas min=(address&mask)+1, max=(address|~mask)−1 respectively.

[0063] Figure 4 is a fourth flow chart of the network address dynamic configuration method of the present invention, based on the above embodiment, converting each integer in the integer range consisting of the minimum value and the maximum value into the corresponding valid address, and adding all the valid addresses to the preset address list, including:

[0064] S21, obtaining all integers in the integer range formed by the minimum value and the maximum value;

[0065] S22. Convert all the integers into their corresponding effective addresses according to the bytes.

[0066] Optionally, in this embodiment, first, since the address of the IPv4 network has 4 bytes, that is, 32 bits, based on this, the number of host number bits can be obtained by subtracting the number of network number bits (that is, the number of subnet mask bits) maskBits from 32; then, the number of host number bits is left-shifted from 0xFFFFFFFFu (32 bits all 1) to obtain a mask mask with all binary 1s for the network number and all binary 0s for the host number.

[0067] Optionally, in this embodiment, when maskBits=23, mask=111111111111111111111110 000000000 (binary) can be calculated.

[0068] Optionally, in this embodiment, the calculation result of min is that the network number is consistent with the given address, and the host number is binary all 0 plus 1; at the same time, the calculation result of max is that the network number is consistent with the given address, and the host number is binary all 0 minus 1. Based on the above embodiment, if address = 3232236032, which is 11000000 10101000 00000010 00000000, then min = 11000000 101010000000010 00000001 (binary), and max = 1100000010101000 00000011 11111110 (binary).

[0069] Similarly, as described in the above example, min = 11000000 10101000 00000010 00000001 (binary), max = 11000000 10101000 00000011 11111110 (binary), a number in the range 1100000010101000 00000010 00000011 (binary), its 4 bytes converted to decimal are 192, 168, 2, 3, and the corresponding IP address is 192.168.2.3.

[0070] Figure 5 The fifth flow chart of the network address dynamic configuration method of the present invention is based on the above embodiment, wherein the step of excluding the connected address of the first aircraft in the connected state from the address list according to the preset configuration period, and performing the connection operation of the second aircraft in the non-connected state according to the remaining address, comprises:

[0071] S31, excluding the connected addresses in the address list according to the configuration period to obtain the remaining addresses;

[0072] S32. Sending preset detection data packets to the remaining addresses according to a preset detection period.

[0073] Optionally, in this embodiment, at configurable intervals, the addresses in the address list list are continuously pinged, excluding connected addresses, so as to send ping packets with very low resource consumption to the remaining addresses as the detection packets of this embodiment.

[0074] Figure 6 is a sixth flow chart of the network address dynamic configuration method of the present invention, based on the above embodiment, the configuration cycle according to the preset configuration period excludes the connected address of the first aircraft in the connected state in the address list, and performs the connection operation of the second aircraft in the non-connected state according to the remaining address, and also includes:

[0075] S33, when receiving the first reply data corresponding to the detection data packet, sending a heartbeat data packet of a preset communication protocol to the source address of the first reply data through the user datagram protocol;

[0076] S34. When receiving the second reply data corresponding to the communication protocol, determine that the source address is the second aircraft to be connected, and establish a communication link with the second aircraft according to the communication protocol.

[0077] Optionally, in this embodiment, after the aircraft in the local area network receives the ping data packet, it will send a reply as the first reply data of this embodiment.

[0078] Optionally, in this embodiment, after receiving the first reply data, the ground control station sends a heartbeat data packet of the communication protocol set by the ground control station to the source address through UDP (User Datagram Protocol); if the second reply data corresponding to the communication protocol is received, the second aircraft at the source address is determined to be the object to be connected of the ground control station.

[0079] Figure 7 is a seventh flow chart of the method for dynamic configuration of a network address of the present invention. Based on the above embodiment, the method further includes:

[0080] S41. When the connection operation with the second aircraft is successfully completed, use the address of the second aircraft as the connected address;

[0081] S42: When the next configuration cycle is reached, exclude the address of the second aircraft from the remaining addresses.

[0082] Optionally, in this embodiment, the configuration cycle of this embodiment is set according to the current ratio of the number of the first aircraft to the number of the second aircraft and the current processing resource state of the ground control station, for example, to quickly discover newly powered-on aircraft and / or to occupy less computer processing resources.

[0083] Optionally, in this embodiment, when each detection data packet or heartbeat data packet is sent in each configuration cycle, it is checked whether each address is included in the preset connection pool, wherein the connection pool of this embodiment adopts a hash set data structure to improve the checking speed.

[0084] Figure 8 FIG. 8 is an eighth flow chart of the method for dynamic configuration of a network address of the present invention. Based on the above embodiment, the method further includes:

[0085] S51, when the first aircraft switches from a connected state to a non-connected state, sending a heartbeat packet to the connected address corresponding to the first aircraft according to a preset monitoring period;

[0086] S52. When the third reply data corresponding to the heartbeat packet is received within the preset monitoring period, the connection status with the first aircraft is restored; when the third reply data is not received within the monitoring period, the connected address corresponding to the first aircraft is used as the remaining address in the next configuration cycle.

[0087] Optionally, in this embodiment, the time period between when the user turns on the search and when the user turns off the search is used as the monitoring period of this embodiment, and the above-mentioned exclusion, sending and connection operations are continuously and cyclically performed during this period, so as to discover newly started aircraft earlier.

[0088] Optionally, in this embodiment, the connected aircraft object is still maintained in the above address list, based on which, even if the aircraft is disconnected for a short time, the ground control station will continue to try to send a heartbeat data packet to its corresponding aircraft. Therefore, when the aircraft's communication is restored, the aircraft can receive the above data packet and make the above reply in a targeted manner, so that the link can be reestablished.
