Description

Technical Field

[0001] The invention belongs to the technical field of wireless communications and relates to a non-safe data distribution method based on a single full network. Background Art

[0002] A single full network is a mobile platform network with a small number of users and single functional requirements. Each network member communication terminal adopts a single send-receive network architecture, which can receive data from other network users while transmitting, greatly improving the network data transmission capacity. Figure 1 shown.

[0003] The network is established as soon as it is turned on, without any routing and network management resource overhead, and real-time interconnection between network members can be achieved. In addition, the single full network has the following two characteristics:

[0004] (1) All members can send messages at the same time.

[0005] (2) At the same time, any member can also receive messages from all other members.

[0006] The communication between two single full networks is achieved by relay members switching between different single full networks in a time-sharing manner.

[0007] The present invention designs a non-safe data distribution method based on a single full network in view of the intercommunication characteristics of two single full networks. This protocol is only one-way transmission and does not have a retransmission function. Summary of the invention

[0008] (I) Purpose of the invention

[0009] The purpose of the present invention is to design a non-safe data distribution method based on a single full network in view of the characteristics of two single full networks intercommunication, so as to realize the function of one-way transmission and no retransmission.

[0010] (II) Technical solution

[0011] In order to solve the above technical problems, the present invention provides a non-secure data distribution method based on a single full network, which adopts a non-secure data distribution protocol for non-secure data distribution. The non-secure data distribution protocol includes a relay message and a start message. The frame formats of the relay message and the start message are different; the start message is sent by the relay member, and other network members start sending relay messages after receiving the start message; the relay message sets a priority, and the relay member sends the relay message according to the priority.

[0012] The relay members and other network members are implemented by a multi-channel wireless communication device installed on a mobile platform.

[0013] The frame format of the relay message includes N bytes, 1 byte is the relay member number, 2 bytes are the destination member number, 3 bytes are the priority, 4 bytes are the data length, 5 to N-1 bytes are data, and N bytes are the checksum.

[0014] In the frame format of the relay message, the relay member number is recorded as Am, and m represents the relay member sequence number; the destination member number is recorded as An, and n represents the destination member sequence number.

[0015] Among them, in the frame format of the relay message, the priority content is 0-255; the data length content is N-5.

[0016] Among them, in the frame format of the relay message, the checksum is the lower 8 bits of the cumulative result of all bytes from 1 to N-1.

[0017] The frame format of the start message includes 4 bytes, and bytes 1 to 4 are all start command words.

[0018] Among them, in a single full network, when relay messages from multiple members are received at the same time, the relay members send the saved relay messages according to the priority.

[0019] Among them, when there are 16 network members, they are recorded as: A1, A2, A3, ..., A16, forming two single full networks, A1~A8 form single full network 1, and the transmission frequency points are set to 1-8 respectively; A9-A16 form single full network 2, and the transmission frequency points are set to 9-17 respectively; set the relay member to A8, the transmission frequency point in single full network 1 is 8, and the transmission frequency point in single full network 2 is 17; relay member A8 sends a start message at the beginning of the single full network 1 moment, and the members of the single full network 1 send relay message 1 after receiving the start message; relay member A8 switches the transmission frequency point to 17 at the beginning of the single full network 2 moment, and sends the saved relay information 1 of the single full network 1 to the members in the single full network 2 after sending the start message, and at the same time receives and saves the message that the single full network 2 needs to send to the single full network 3.

[0020] (III) Beneficial effects

[0021] The non-secure data distribution method based on a single full network provided by the above technical solution consists of two types of messages: relay messages and start messages. Each type of message has a unique frame format; the start message is sent by the relay member, and other network members start sending relay messages after receiving the start message; the relay message sets a priority, and the relay members send the relay message according to the priority; the function of one-way sending only and no retransmission is realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples.

[0025] This embodiment is based on a non-secure data distribution method for a single full network, and adopts a non-secure data distribution protocol for non-secure data distribution. The non-secure data distribution protocol includes a relay message and a start message. The frame formats of the relay message and the start message are different; the start message is sent by the relay member, and other network members start sending relay messages after receiving the start message; the relay message sets a priority, and the relay member sends the relay message according to the priority.

[0026] Among them, relay members and other network members are realized by multi-channel wireless communication devices installed on mobile platforms.

[0027] The frame format of the relay message is as follows:

[0028]

[0029] The checksum is the lower 8 bits of the sum of all bytes from 1 to N-1.

[0030] The frame format of the start message is as follows:

[0031] Byte sequence number name content 1 Start command word A0 2 Start command word A0 3 Start command word A0 4 Start command word A0

[0032] In a single full network, when relay messages from multiple members are received at the same time, the relay members send the saved relay messages according to the priority.

[0033] Taking two single full networks consisting of 16 network members A1, A2, A3, ..., A16 as an example, the steps of the non-secure data distribution method of this embodiment are:

[0034] In the first step, after power-on, A1-A8 form a single full network 1, and the transmission frequency points are set to 1-8 respectively; A9-A16 form a single full network 2, and the transmission frequency points are set to 9-17 respectively. Set the relay member to A8, the transmission frequency point in the single full network 1 is 8, and the transmission frequency point in the single full network 2 is 17.

[0035] The second step is, Figure 2 As shown, relay member A8 sends a start message at the beginning of single full network 1, and members of single full network 1 send relay message 1 after receiving the start message.

[0036] In the third step, relay member A8 switches the transmission frequency to 17 at the beginning of single full network 2 and sends the start message, then sends the saved relay information 1 of single full network 1 to the members in single full network 2, and at the same time receives and saves the message that single full network 2 needs to send to single full network 3.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
