High speed 1553B bus communication system error correction method

Abstract

The invention, which belongs to an error correction method, especially relates to a high speed 1553B bus communication system error correction method. A waveform of a Manchester coding signal transmitted on a 1553B communication system cable generates distortion because a speed is increased and there is an error in the system communication. By using the error correction method of the invention, the above problems can be solved. In the method, the signal is successively processed by a signal high-speed sampling module, an error detection module, an error compensation module, an error storage module and an error correction module. The signal high-speed sampling module comprises: a high speed sampling clock and a counter. The error detection module is used to determine a counting signal output by the signal high-speed sampling module. The error correction module carries out error correction processing to the received signal according to an error value stored in the error storage module. The high speed 1553B bus communication system error correction method provided in the invention is easy to be realized. Costs are low and an effect is obvious. A bottleneck of the1553B high speed bus communication whose speed is more than 10Mbit / s can be broken through.

Description

technical field [0001] The invention belongs to an error correction method, in particular to an error correction method for a high-speed 1553B bus communication system. Background technique [0002] MIL-STD-1553B is a military bus standard introduced by the US military in the 1970s to realize the integration of aircraft electronic systems. Because of its good openness and adaptability, it has been widely used in the aerospace industry. Foreign satellites, major transportation rockets, and domestic satellites and spaceships also generally use this bus as a channel for data transmission and sharing. However, with the development of weapons and equipment in our country and the improvement of weapons manufacturing capacity, the speed of the original 1553B bus for ammunition is far from meeting the requirements of the development of weapons and equipment. For this reason, it is necessary to be compatible with the original protocol and the original bus cable, such as figure 1 S...
