Optical fiber serial data communication method

Abstract

The embodiment of the invention provides an optical fiber serial data communication method. The method comprises the following steps: adding a standard sending clock signal in a data frame, wherein the standard sending clock signal comprises high level signal and / or low-level signal with preset amount, and a data receiving determines a sampling clock cycle according to the received standard sending clock signal when receiving the data frame, thereby generating a corresponding sampling clock signal; and sampling the data part of the data frame by using the sampling clock signal so as to acquirea corresponding data packet in the data frame. Since the data frame contains the standard sending clock signal, the data receiving end can self-adaptively generate the corresponding sampling clock signal according to the standard sending clock signal to realize the receiving of the data frame whether the data sending end sends the data frame in any communication rate; the data sending end can flexibly adjust the communication rate of the data frame, and the data receiving end can self-adaptively receive the data frames in different communication rates.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and more specifically, to a method for optical fiber serial data communication. Background technique [0002] With the continuous deepening of the intelligentization process of power electronic systems, the interconnection and intercommunication between multiple devices is gradually strengthening, and there is a great demand for cost-effective data communication methods. Considering the strong electromagnetic interference environment inside power electronic equipment and reducing the complexity of interconnection lines as much as possible, the industry generally uses optical fiber communication to achieve reliable data transmission between devices. Combined with the constant switching frequency control mode adopted by the power electronic system, the data communication between devices also needs to be transmitted at a constant switching frequency, that is, the data...

Problems solved by technology

In the current data communication method, the data receiving end receives the data frame with a pre-agreed sampling clock signal. The pre-agreed sampling clock signal has a specific sampling clock cycle. When it is larger, the data receiving end cannot complete the correct reception of the data frame
