in step S1001, the internet of things device enters a promiscuous mode, and monitors a data packet received by the fixed port P1;
in step S1002, the mobile phone APP sends a data packet containing the ssid and password to the fixed port P1;
in step S1003, the router forwards the data packet sent by the mobile phone APP to the internet of things device;
in step S1004, a fixed port P1 of the internet of things device receives the data packet, and connects to the router according to the ssid and password in the data packet;
in step S1005, the mobile phone APP monitors a data packet received by the fixed port P2;

in step S1008, when the fixed port P2 of the mobile phone APP receives the distribution network success broadcast packet, the distribution network succeeds.
However, the SmartConfig distribution network technology is prone to a phenomenon that the distribution network fails all the time, because a port (i.e., the fixed port P2 in fig. 1) through which the terminal receives the distribution network successful broadcast packet is single and is dead, and when the single receiving port is occupied, the terminal cannot receive the distribution network successful broadcast packet. For example, in fig. 1, when the terminal is a mobile APP, the fixed port P2 of the terminal that receives the distribution network successful broadcast packet is occupied by the system or another application, and once the fixed port P2 is occupied, even if the internet of things device sends the distribution network successful broadcast packet to the mobile APP for many times, the mobile APP still cannot receive the distribution network, which results in that the distribution network always fails. Therefore, the existing SmartConfig network distribution technology has the phenomenon that a port is occupied and the network distribution is unsuccessful, has high delay, low success rate and lack of high efficiency and timeliness, and brings inconvenience to users. In conclusion, how to prevent the ports from being occupied and improve the success rate of the distribution network in the process of the distribution network is a problem to be solved urgently.
Fig. 2 is a schematic flow chart of a network distribution method applied to an internet of things device according to an embodiment of the present invention, which includes steps S101 to S102, where:
in step S101, the internet of things device enters a promiscuous mode to monitor a broadcast packet received by the first port of the internet of things device, where the terminal sends a plurality of broadcast packets to the first port of the internet of things device via the router, and each broadcast packet includes different port offsets. Therefore, the Internet of things equipment is effectively networked by monitoring the broadcast packet received by the fixed first port.
In step S102, the internet of things device is connected to the router according to the broadcast packet received by the first port, and sends a distribution network success broadcast packet to the terminal through the router according to the port offset therein, where the terminal sets a plurality of offset ports according to the port offset, and when at least one offset port receives the distribution network success broadcast packet, the distribution network succeeds. Therefore, the terminal is provided with the plurality of random offset ports, the internet of things equipment sends the distribution network success broadcast packet to the plurality of offset ports, the phenomenon that the distribution network fails due to the fact that a single port is occupied is prevented, and the terminal can timely and effectively receive the distribution network success packet.
The distribution network mode all adopts a UDP (User Datagram Protocol) broadcast Protocol. The UDP broadcast protocol needs to know port numbers of opposite parties, the first port is a port of an internet of things device, the second port is a port of a terminal, and the two ports are ports determined by an engineer in a development stage. The Internet of things equipment and the terminal monitor the first port and the second port respectively, and data packets transmitted by the opposite side and forwarded by the router can be obtained. Because the port of the Internet of things equipment is not occupied and the port of the terminal is very easy to be occupied, the invention establishes a plurality of random offset ports so as to receive the successful broadcast packet of the distribution network and prevent the phenomenon that the successful broadcast packet of the distribution network cannot be received because the fixed second port is occupied.
The broadcasting packet is a data packet comprising an ssid and a password, and when the internet of things equipment receives the broadcasting packet through the first port, the internet of things equipment is connected with the router according to the ssid and the password, so that effective distribution network connection is guaranteed.
According to the method, the terminal is used for sending a plurality of broadcast packets containing the port offset to the Internet of things equipment, a plurality of random offset ports are established according to the port offset, and when the Internet of things equipment receives and analyzes the port offset in the broadcast packets, the distribution network success broadcast packets can be sent to the plurality of random offset ports of the terminal according to the port offset. In conclusion, the invention establishes an effective random port mechanism by using the port offset, sets a plurality of random offset ports to receive the successful packet of the distribution network through the port offset, prevents the phenomenon of distribution network failure caused by the occupation of a single port, ensures the high efficiency and the success rate of the distribution network, and is convenient for users to use.
Referring to fig. 3, fig. 3 is a schematic flow chart illustrating a process of sending a distribution network success packet according to an embodiment of the present invention, where step S102 includes steps S1021 to S1023, where:
in step S1021, when the internet of things device monitors a plurality of broadcast packets received by the first port, a port offset corresponding to each broadcast packet is analyzed. Therefore, the Internet of things equipment effectively sends the distribution network success packet according to the port offset.
In the development process, a byte with a fixed position is added in a broadcast packet protocol, the byte is the port offset, and when the internet of things equipment receives a broadcast packet, the corresponding port offset can be directly obtained from a data stream according to the fixed position of the data stream.
In step S1022, the internet of things device determines, according to the port offset corresponding to each broadcast packet, an offset port corresponding to each broadcast packet. Therefore, the Internet of things equipment determines the corresponding offset port according to the port offset, and accordingly sends the distribution network success broadcast packet to the plurality of random offset ports.
In step S1023, the internet of things device sends a distribution network success broadcast packet to each offset port via the router. Therefore, the internet of things equipment sends distribution network success broadcast packets to the offset ports according to the analysis result, and the distribution network success probability is effectively increased.
Optionally, in the step of determining, by the internet of things device, an offset port corresponding to each broadcast packet according to the port offset, the method includes: and the Internet of things equipment respectively adds the port number of a preset second port to the port offset corresponding to each broadcast packet to determine the offset port corresponding to each broadcast packet, wherein the second port is a designated port locked by the terminal. Therefore, the second port is a designated port locked by the terminal, so that a plurality of random offset ports can be effectively established according to the second port and random port offset, the probability of receiving successful packets of the distribution network is increased, and the success rate of the distribution network is effectively improved.
Optionally, the second port is a port used by the terminal in the original SmartConfig technology to listen to a distribution network successfully broadcast packet, and the port offset is a self-increasing or random number. Different offset is added on the basis of the port number of the original second port, so that a plurality of temporary random ports are derived, the difference and the randomness of the offset ports established corresponding to each broadcast packet are ensured, and the success rate of the distribution network is effectively improved. For example, if the port number of the second port is 10101010 and the port offset of a broadcast packet is 1, the port number of the offset port of the broadcast packet is determined by adding the corresponding port offset to the port number of the second port, which is 10101011.
To illustrate with a specific numerical example, when a terminal sends three broadcast packets to a first port: the method comprises a first broadcast packet, a second broadcast packet and a third broadcast packet, wherein a first port offset contained in the first broadcast packet is portOffset _1, a second port offset contained in the second broadcast packet is portOffset _2, a third port offset contained in the third broadcast packet is portOffset _3, the port offsets are different from each other, a second port of a terminal is P2, and the determination process of the corresponding offset ports is as follows:
a first offset port corresponding to the first broadcast packet is P4, the first offset port P4 is a random port determined by adding the port number of the second port P2 to the offset portOffset _1 of the first port, and at this time, the port number of the first offset port P4 is (port number of P2 + portOffset _ 1);
the second offset port corresponding to the second broadcast packet is P5, the second offset port P5 is a random port determined by adding the port number of the second port P2 to the second port offset portOffset _2, and at this time, the port number of the second offset port P5 is (port number + portOffset _2 of P2);
the third offset port corresponding to the third broadcast packet is P6, and the third offset port P6 is a random port determined by adding the third port offset portOffset _3 to the port number of the second port P2, where the port number of the third offset port P6 is (port number of P2 + portOffset _ 3).
Wherein the first port offset portOffset _1 、 The second port offset portOffset _2 and the third port offset portOffset _3 are random quantities in the corresponding broadcast packet, and may be different numbers added by itself or different numbers randomly. Therefore, the first offset port P4 corresponding to the first broadcast packet, and the second broadcast packetThe corresponding second offset port P5 and the third offset port P6 corresponding to the third broadcast packet are different from each other, so that randomness and difference of port offset are effectively utilized, and a plurality of random offset ports are established. When the internet of things equipment sends a distribution network success broadcast packet to a plurality of random offset ports, as long as one random offset port of a first offset port P4 corresponding to a first broadcast packet, a second offset port P5 corresponding to a second broadcast packet and a third offset port P6 corresponding to a third broadcast packet is received, the distribution network can be considered to be successful, and the phenomenon that the distribution network fails due to the fact that a second port P2 is occupied is avoided.
According to the distribution network method applied to the Internet of things of the Internet of things equipment, the plurality of ports are arranged through the offset to receive the successful distribution network packet, the phenomenon that the distribution network fails due to the fact that a single port is occupied is prevented, and the high efficiency and the success rate of the distribution network are guaranteed.

Therefore, the terminal sends the broadcast packet, and the Internet of things equipment effectively performs networking by monitoring the broadcast packet received by the fixed first port.
