Problems solved by technology

Due to the untimely perception of packet loss, a large number of retransmitted data packets will be caused, which will affect the overall performance
The full response mode of asynchronous transmission can only handle the packet loss of business data packets. If the single-bit response information packet is lost, the sender cannot confirm the packet receipt of the sensing receiver.

Embodiment 1

[0037] Embodiment 1: A data sending and receiving method applied in a power one-way transmission system, such as figure 1 As shown, it includes: the sending end sends data packets to the receiving end in sequence, and at the same time receives the first response signal from the receiving end sequentially for each data packet that can be received correctly. If the first response signal from the receiving end is received, it means that the receiving end has indeed received the data packet. package case.

[0038] The receiving end receives the data packets sent from the receiving end in order, and sends the first response signal to the sending end for each data packet that can be received correctly in turn, so that the sending end confirms that the receiving end has received the data packet and is ready to recycle. Memory.

[0039] like figure 1 As shown, the sending end sends a data packet to the receiving end, and when the first data packet is successfully received, the rece...

Embodiment 2

[0042] Embodiment 2: as figure 2 As shown, on the basis of Embodiment 1, the sending end sends data packets to the receiving end, and if the receiving end finds discontinuous data packets for the first time, it discards the subsequent discontinuous data packets and sends a second discontinuous data packet to the sending end. Acknowledgment signal, so that the sending unit resends the data packet from the data packet that has never received the first acknowledgment signal, and the receiving end starts to receive again from the first discontinuous data packet. In this embodiment, the second response signal is 0x00. After the sending end receives the 0x00 signal sent by the sending end, it starts to resend the data packet from the first discontinuous data packet found by the receiving end. At this time, if the receiving end will receive repeated data, the receiving end will reply 0xff to the repeated data, so that the first response signal (0xff) received by the sending end is ...

Embodiment 3

[0044] Embodiment 3: as image 3 , on the basis of Embodiment 1, after the sending end sends a data packet to the receiving end every time, if the receiving end receives the data packet correctly, it sends the first response signal (adopting 0xff in this embodiment) to the sending end. If the sending end sends the second data packet to the receiving end, the data packet is lost, and the receiving end does not return 0xff to the sending end.

[0045] After sending all data packets, the number of first response signals received by the sending end is not equal to the number of data packets sent, and the sending end checks the buffer within the number of times set by the timer (this embodiment sets 2 times) If there is data and the first response signal is not received during the period, the data packet that has not received the first response signal is resent, and the first response signal sent by the receiving end indicating that the data packet is received correctly is received...

Abstract

The invention discloses a data receiving and transmitting method and device applied to an electric power one-way transmission system, and the method comprises the steps: enabling a transmitting end to receive a first response signal which is transmitted from a receiving end for each data packet capable of being correctly received, and representing that the receiving end really receives the data packet, wherein the number of the first response signals received by the sending end is the number of the data packets received by the receiving end. The sending end can confirm and perceive the packet receiving condition of the receiving end according to the number of the received first response signals, so that the problem of unreliability of asynchronous transmission is solved under the condition of ensuring high performance of asynchronous transmission.

Description

technical field [0001] The invention relates to a data sending and receiving method applied in a power one-way transmission system, and belongs to the technical field of data transmission, in particular to the technical field of power system data transmission. Background technique [0002] The current one-way power transmission system has the following constraints: [0003] 1. Only UDP protocol is allowed to pass. [0004] 2. The file can be sent from the sender to the receiver arbitrarily (a file may contain several data packets), and the receiver can only send one byte of 0x00 or 0xff (single-bit information) to respond. [0005] 3. The number of single-bit information in response cannot exceed the number of data packets. [0006] Due to the above limitations, it is more difficult to ensure the reliability and high performance of data transmission than ordinary systems. [0007] At present, the common transmission methods in the power one-way transmission system are as...
