Digital decoding communication interface and method based on rs-422 serial interface

Abstract

The invention provides a digital decoding communication interface and method based on a RS-422 serial interface. The interface comprises a RS-422 serial interface module, a filter integer module, a logic control module, a serial-parallel conversion module and a decoding module. The RS-422 serial interface module receives input serial data. The serial data is converted into door-control signals, clock signals and serial data through the filter integer module. The logic control module implements logic control under the control of the door-control signals and the clock signals according to the requirements. The serial-parallel conversion module converts the serial data into parallel data according to the logic control. The decoding module supplies the parallel data to single or multiple decoding units for decoding so as to implement the control. According to the design manner of complete hardware circuits, rapid communication and precision decoding of satellite products are implemented, the serial communication manner is adopted, the circuit logic function is flexible and controllable, design is simple, design cost is saved, and the total satellite resource occupation is reduced.

Description

technical field [0001] The invention relates to the technical field of satellite product communication interfaces, in particular to a pure hardware digital decoding communication interface and method based on an RS-422 serial interface. Background technique [0002] At present, the communication interface of satellite products is a parallel communication method, and a large-scale integrated chip is used for serial-to-parallel conversion and decoding. This method takes up more resources of the whole star and also increases the complexity of the design of the product itself. [0003] With the continuous improvement of the communication complexity between satellite products and the need to minimize the resource occupation of the entire satellite platform, the existing communication interface can no longer meet the demand. [0004] Do not find description or report similar to the present invention at present, also do not collect similar data both at home and abroad. Contents ...
