Abstract

The present invention provides a high-reliability serial transmission processing method which is suitable for the programmable hardware and the device, which includes a receiving port, a receiving control module and a controlled receiving module, the receiving control module scans the prescribed number n of the receiving port in each receiving period and defines the interval between each scanning as one scanning period; judging whether the value of current receiving port has changed after the completion of each scanning; and the receiving module receives one bit information from the receiving port when the triggering signal of the receiving control module is received. The invention can settle the problem of wrongly receiving caused by the disaccording of the crystal vibration between the receiving and transmitting equipment; can settle the problem of wave distortion at the receiving end caused by the transmission medium and the transmission circuit and increases the reliability of the communication.

Description

technical field

[0001] The present invention relates to the field of transmission between two devices through a medium such as an optical fiber, etc., with a method of serial communication. The phase shift caused by the influence of the waveform distortion caused by the communication medium reduces the communication reception processing method that requires the communication transceiver circuit. Background technique

[0002] The serial communication technology has been widely used in the industrial field because of its simple equipment and convenient implementation. A branch of its field, optical communication, is especially suitable for use in places with strong electromagnetic interference because of its strong anti-interference and long transmission distance. However, there are two problems in the existing serial communication technology: the first problem is that the sending and receiving equipment uses different clock crystal oscillators, and the phase shift of the rec...
