The invention relates to the technical field of electric power communication, and specifically relates to transmission and reception method for an electric power terminal to change the length of a data frame and an apparatus. The transmission method for the electric power terminal to change the length of the data frame comprises the following steps: the error rate of present communication of the electric power terminal is detected; when the error rate exceeds a threshold value, fame length adjusting is carried out on a to-be-transmitted data frame according to a predetermined frame length adjusting strategy; and the adjusted data frame which has been subjected to the data length adjusting is transmitted according to an original communication protocol of the electric power terminal. Through the apparatus and the method of the above embodiment, the frame length of the data transmitted by the electric power terminal can be automatically adjusted to raise the reliability of the electric power terminal communication.
Description
technical field [0001] The invention relates to the technical field of electric power communication, in particular to a method and device for transmitting and receiving variable data frame lengths of electric power terminals. Background technique [0002] There are two ways of communication, parallel communication and serial communication. In multi-computer systems and modern measurement and control systems, information exchange mostly adopts serial communication (such as Image 6 Shown is a schematic structural diagram of serial communication in the prior art). [0003] Asynchronous communication is transmitted in units of characters (frames), and the gap (time interval) between characters is arbitrary, but the bits in each character are transmitted at a fixed time, that is, there is no gap between characters. There must be an integer multiple of the "bit interval", but the distance between bits in the same character is an integer multiple of the "bit interval". [0004] ...
